Document: https://controllertestonline.com/tools.md # ControllerTest — tests and site guide Canonical page: https://controllertestonline.com/ Language: English Last updated: 2026-10-08 Free online controller tester for buttons, sticks, drift, polling rate, triggers, vibration and reports. ControllerTest is an independent browser-based controller diagnostic website. It is not affiliated with Microsoft, Sony, Nintendo, Valve or controller manufacturers. ## Testing workflow 1. **Connect and wake:** Connect by USB, Bluetooth or adapter, then press any controller button so the browser can expose the Gamepad API device. 2. **Press, move and sample:** Press every button, pull both triggers, rotate both sticks, then collect drift, circularity and polling samples in the same browser session. 3. **Review and export:** Review the health score, failing metrics and export options for resale checks, repair notes or support tickets. ## Controller Tester Online & Gamepad Health Check Page: https://controllertestonline.com/ Source last updated: 2026-07-22 Use this free gamepad tester to run a full controller health check in your browser. Test buttons, analog sticks, triggers, stick drift, deadzone, polling stability, vibration support and exportable report data. ControllerTest reads the Gamepad API locally. It can reliably show input state, stick center offset, trigger values and browser-exposed haptics. Polling rate is estimated from browser timestamps, so use it for setup comparisons rather than hardware-lab certification. ## Stick Drift Test Online Page: https://controllertestonline.com/stick-drift-test/ Source last updated: 2026-07-22 Keep your hands off both analog sticks and run an 8-second rest sample. The drift test reports left and right center offset, drift severity, sample confidence and a recommended game deadzone. The tool measures analog stick distance from the center while the controller is idle. A small offset is normal. A large or unstable offset means the game may receive movement even when you are not touching the stick. ControllerTest does not repair drift. It gives a repeatable browser-based reading and a deadzone suggestion that can help you decide whether to adjust settings, clean the stick, or replace the module. ## Controller Polling Rate Test Page: https://controllertestonline.com/controller-polling-rate-test/ Source last updated: 2026-06-25 Move a stick for 8 to 10 seconds to estimate browser-visible gamepad Hz, input interval, jitter, sample count and stability. Use the same browser and PC to compare USB, Bluetooth and 2.4G controller modes. ControllerTest samples the browser Gamepad API and converts visible timestamp or input-change deltas into average Hz, peak Hz, interval, jitter and stability. The result is a browser-layer estimate, not a raw USB analyzer capture. Browser scheduling, display refresh, drivers, Bluetooth stacks and USB power management can all change the number you see. ## Controller Deadzone Test Page: https://controllertestonline.com/deadzone-test/ Source last updated: 2026-07-22 Run an 8-second rest sample to calculate a practical game deadzone. Use the recommendation, safety margin and threshold circle to hide stick center noise without masking real movement. A good deadzone is slightly larger than the controller's idle stick offset. Too low and drift causes unwanted movement. Too high and aim or steering feels sluggish near center. Run the stick drift sample first. ControllerTest adds a small safety margin to the largest observed center offset and reports that as a practical starting point for game settings. ## Controller Circularity Test Page: https://controllertestonline.com/circularity-test/ Source last updated: 2026-06-25 Choose a stick, start the circularity pass and rotate smoothly around the full outer gate. The tool visualizes trace shape, coverage, circularity error, sample count and whether the stick reaches full range evenly. Circularity testing focuses on the stick's outer travel. A controller can pass a center drift check but still have flat spots, weak diagonals or limited range near the physical gate. ControllerTest reads browser-visible Gamepad API axes during a timed rotation. Use the result to compare left and right sticks, tune outer-deadzone style settings and decide whether cleaning, calibration or repair is worth checking. ## Controller Vibration Test Page: https://controllertestonline.com/vibration-test/ Source last updated: 2026-09-23 Connect a controller, press any button, then run a short vibration test. Check weak and strong rumble and learn what the result means. Vibration depends on browser, operating system, controller model, connection mode and driver behavior. A controller can rumble in native games while still not exposing a compatible haptic actuator to the browser. ControllerTest checks browser-exposed haptic capability and sends short pulses through the Gamepad API path when available. It does not measure physical motor force, vibration latency or DualSense adaptive trigger resistance. ## Xbox Controller Tester Page: https://controllertestonline.com/xbox-controller-test/ Source last updated: 2026-06-25 Test Xbox Series, Xbox One, Xbox Elite and Xbox-style PC controllers. Check A/B/X/Y, bumpers, triggers, sticks, D-pad, vibration support and export a health report. Most Xbox controllers expose a standard browser mapping: A, B, X, Y, LB, RB, LT, RT, menu, view, sticks and D-pad. If the controller does not appear, connect by USB first, press a button, then retry Bluetooth or the Xbox wireless adapter. ## PS5 Controller Test Page: https://controllertestonline.com/ps5-controller-test/ Source last updated: 2026-09-23 Connect your DualSense to test PS5 button input, stick drift and L2/R2 trigger travel. Follow the checks below to understand what each browser reading means. The browser can read standard Gamepad API input when the DualSense is exposed by the operating system. Adaptive trigger resistance is not normally controllable through the standard browser API. Use USB for the most consistent first test. ## Switch Controller Test Page: https://controllertestonline.com/switch-controller-test/ Source last updated: 2026-06-25 Test Switch Pro Controller and Joy-Con input in the browser. Check stick drift, circularity and button mapping before deciding whether a controller needs recalibration or repair. Switch controllers can expose different browser mappings depending on OS, Bluetooth stack and driver. Joy-Con drift is commonly a center-offset issue, so the stick drift sample and deadzone guidance are the most important checks on this page. ## Controller Input Test Page: https://controllertestonline.com/controller-input-test/ Source last updated: 2026-07-22 Use the live input test to inspect button presses, trigger values and analog axes. This is the fastest way to confirm whether the browser sees your game controller correctly. Each button should light up once when pressed and turn off cleanly when released. Analog axes should return near 0.00 at rest and move smoothly toward -1.00 or 1.00 at full travel. If a button never changes, a trigger does not reach full range, or an axis jumps while idle, run the drift and deadzone tests before deciding whether the controller needs service. ## Gamepad Tester Online Page: https://controllertestonline.com/gamepad-tester-online/ Source last updated: 2026-07-22 Open the browser gamepad tester, press any button to connect, then check live buttons, analog sticks, trigger values, drift, deadzone and vibration support. The tester reads the Gamepad API locally and turns browser-visible input into a practical controller health check for PC and console-style gamepads. Use it before buying a used gamepad, after changing drivers, or when a game does not seem to read buttons, sticks or triggers correctly. ## Joystick Tester Online Page: https://controllertestonline.com/joystick-tester/ Source last updated: 2026-06-25 Use this joystick tester to watch analog stick axes live, check whether the stick returns to center, and confirm the outer gate reaches full range. A healthy analog stick should rest near the center, move smoothly across the axis range, and return without large jumps or stuck values. If the stick rests off-center, run the drift and deadzone tests. If it does not reach the outer edge evenly, use circularity to inspect gate travel. ## Controller Latency Test Page: https://controllertestonline.com/controller-latency-test/ Source last updated: 2026-06-25 Use browser-visible polling and input updates to compare controller latency symptoms across USB, Bluetooth and 2.4G setups on the same system. A web page cannot measure end-to-end display latency like a hardware rig. It can still show update stability, dropped input patterns and polling differences between connection modes. For useful comparisons, test the same controller in the same browser, close heavy apps and repeat the sample after switching between USB, Bluetooth and adapters. ## Gamepad Mapping Test Page: https://controllertestonline.com/gamepad-mapping-test/ Source last updated: 2026-06-25 Use the mapping test to see which browser button index, axis and trigger value changes when you press each control on the gamepad. Browsers, operating systems and drivers can expose the same controller with different button labels or axis order, especially for Switch, generic and specialty controllers. The mapping page helps you document what the browser sees before changing game settings, emulator bindings or repair notes. ## Switch Joy-Con Drift Test Page: https://controllertestonline.com/switch-joy-con-drift-test/ Source last updated: 2026-06-25 Connect a Joy-Con or Switch Pro controller, leave the stick untouched, and measure center offset before checking deadzone and circularity. Joy-Con drift often appears as a center offset: the stick reports movement even while untouched. The browser can show that offset when the controller is exposed through the Gamepad API. Use the result as a condition check, not a repair claim. Severe drift usually needs cleaning, calibration in system tools, warranty service or stick module replacement. ## PS Controller Calibration Guide Page: https://controllertestonline.com/ps-controller-calibration/ Source last updated: 2026-06-25 Use browser diagnostics to check whether a PlayStation controller shows drift, trigger range issues or deadzone symptoms before changing game settings. ControllerTest cannot write firmware settings or recalibrate a PlayStation controller. It can show browser-visible stick center, axis movement, trigger travel and vibration capability. Use those readings to decide whether to adjust in-game deadzone, try USB, clean the stick, run platform tools or seek repair. ## Reports and data Reports, JSON, CSV and share cards are generated on the user's device.

Results describe input exposed by the browser and the local operating system, driver and connection. They do not certify hardware health, repair success, raw USB electrical polling or end-to-end button-to-photon latency. The health score is a diagnostic summary, not a manufacturer certificate. ## General questions ### Why does the page say press any button to connect? Browsers usually hide gamepads until the user physically interacts with the controller. Press any controller button after connecting the device. ### What does the controller health score mean? It is a practical browser diagnostic summary based on visible input, drift, trigger range, circularity, polling stability and vibration capability. Use it as triage, then open the related specialized test for any weak area. ### Can this controller test fix stick drift? No. It measures drift and recommends a deadzone for games. Severe drift usually requires cleaning, stick module replacement or warranty service. ### How is controller polling rate measured? The tool estimates update rate from Gamepad timestamps and visible input changes. It is a browser-layer estimate, not a USB analyzer reading. ### Does it support PS5 adaptive triggers? The standard browser Gamepad API can read trigger travel when exposed, but it does not provide normal control over DualSense adaptive trigger resistance. ### Is my controller data uploaded? No. The test runs locally in the browser. Reports, CSV, JSON and share cards are generated on your device. ### Should I use the homepage or a specialized test page? Start with the homepage for a full controller health check. Use the drift, deadzone, polling, circularity or vibration page when you need a deeper explanation of one specific result. ### Which browsers work best for controller testing? Chrome and Edge usually expose the broadest Gamepad API behavior on Windows. Firefox also works for input testing, while vibration and mappings can vary by controller and operating system. ## Stick Drift Test Online Page: https://controllertestonline.com/stick-drift-test/ Source last updated: 2026-07-22 Keep your hands off both analog sticks and run an 8-second rest sample. The drift test reports left and right center offset, drift severity, sample confidence and a recommended game deadzone. The tool measures analog stick distance from the center while the controller is idle. A small offset is normal. A large or unstable offset means the game may receive movement even when you are not touching the stick. ControllerTest does not repair drift. It gives a repeatable browser-based reading and a deadzone suggestion that can help you decide whether to adjust settings, clean the stick, or replace the module. ### Can this stick drift test fix my controller? No. It measures center offset and suggests a practical game deadzone. Physical drift usually needs cleaning, calibration software, warranty service or stick replacement. ### What is a good stick drift value? Under 0.04 is usually minimal center noise. Values from 0.04 to 0.08 are borderline, and 0.08 or higher is likely to be visible in some games. ### Should I touch the sticks during the drift sample? No. Keep both sticks untouched for the full sample. Any movement during the sample makes the result look worse than the controller's true idle behavior. ### How is the recommended deadzone calculated? The tool looks at the largest left or right stick offset seen during the sample, adds a 0.02 safety margin, and keeps the suggestion inside a practical 0.04 to 0.30 range. ### Which stick matters more? It depends on the game. Right-stick drift usually affects camera or aim, while left-stick drift can move a character or menu selection without input. ### Why is a small drift value normal? Analog sticks rarely rest at a perfect zero. A tiny offset or jitter is normal and is exactly why most games include a deadzone setting. ### Why does my game feel different from the browser reading? Games can apply their own deadzone, sensitivity curve, platform calibration or Steam Input profile. Use the browser result as a raw condition check, then tune the game separately. ### Do Hall Effect or TMR sticks completely prevent drift? They reduce common wear paths by using magnetic sensing, but centering springs, firmware calibration, dirt, adapters and mapping layers can still affect the idle reading. ## Controller Deadzone Test Page: https://controllertestonline.com/deadzone-test/ Source last updated: 2026-07-22 Run an 8-second rest sample to calculate a practical game deadzone. Use the recommendation, safety margin and threshold circle to hide stick center noise without masking real movement. A good deadzone is slightly larger than the controller's idle stick offset. Too low and drift causes unwanted movement. Too high and aim or steering feels sluggish near center. Run the stick drift sample first. ControllerTest adds a small safety margin to the largest observed center offset and reports that as a practical starting point for game settings. ### What deadzone should I use? Start slightly above the largest idle stick offset reported by the sample. Then test in game and lower it until unwanted movement just stops. ### Is a zero deadzone better? Only if the stick centers extremely well. A zero deadzone often exposes normal analog noise as camera or movement drift. ### Does deadzone repair stick drift? No. Deadzone hides small unwanted input in software. It does not clean, recalibrate or replace the physical stick module. ### Why does a high deadzone feel bad? A high deadzone ignores more movement near center, so small aiming, steering or menu inputs may feel delayed or less precise. ### Should left and right sticks use different deadzones? Use separate values when a game supports them and one stick measures worse than the other. Right-stick camera control often needs a tighter setting than left-stick movement. ### Why does my game not match the browser recommendation? Games use different slider scales, response curves, platform calibration and sometimes separate inner and outer deadzones. Treat the browser value as a starting point. ### What is inner versus outer deadzone? Inner deadzone ignores movement near center. Outer deadzone controls when the game treats the stick as fully tilted. This page focuses on inner deadzone. ### When should I repair instead of raising deadzone? If the recommended value is repeatedly above 20%, or the controller still moves after a high setting, inspect calibration, cleaning, warranty service or stick replacement. ## Controller Circularity Test Page: https://controllertestonline.com/circularity-test/ Source last updated: 2026-06-25 Choose a stick, start the circularity pass and rotate smoothly around the full outer gate. The tool visualizes trace shape, coverage, circularity error, sample count and whether the stick reaches full range evenly. Circularity testing focuses on the stick's outer travel. A controller can pass a center drift check but still have flat spots, weak diagonals or limited range near the physical gate. ControllerTest reads browser-visible Gamepad API axes during a timed rotation. Use the result to compare left and right sticks, tune outer-deadzone style settings and decide whether cleaning, calibration or repair is worth checking. ### What is controller circularity? Controller circularity describes how evenly an analog stick reaches the outer gate in every direction while you rotate it around the edge. ### What is a good circularity error? In the current test, under 7% error with over 85% coverage is treated as a pass. Under 13% error with over 75% coverage is borderline. ### Why does my trace look square or diamond-shaped? A square or diamond trace can come from snapping between directions, limited diagonal travel, remapping software, calibration issues or worn stick hardware. ### Why is my coverage low? Low coverage usually means the stick did not reach the outer edge, the wrong stick was selected, the movement was incomplete, or the browser mapping is limiting the axis range. ### Is circularity the same as stick drift? No. Stick drift measures center offset while the stick is untouched. Circularity measures outer travel while you intentionally rotate the stick at full range. ### Can deadzone fix poor circularity? Inner deadzone can hide center noise, but it does not repair poor outer-gate travel. Some games offer outer deadzone or response curves that can compensate for mild range issues. ### Should I test both sticks? Yes. Left and right sticks wear differently, and the stick used for camera aim, steering or aiming may need a cleaner trace than the movement stick. ### Why do browser results differ from games? Browsers read mapped Gamepad API axes. Games may use native drivers, their own calibration, response curves, deadzones and platform-specific controller profiles. ## Controller Polling Rate Test Page: https://controllertestonline.com/controller-polling-rate-test/ Source last updated: 2026-06-25 Move a stick for 8 to 10 seconds to estimate browser-visible gamepad Hz, input interval, jitter, sample count and stability. Use the same browser and PC to compare USB, Bluetooth and 2.4G controller modes. ControllerTest samples the browser Gamepad API and converts visible timestamp or input-change deltas into average Hz, peak Hz, interval, jitter and stability. The result is a browser-layer estimate, not a raw USB analyzer capture. Browser scheduling, display refresh, drivers, Bluetooth stacks and USB power management can all change the number you see. ### Is this controller polling rate test accurate? It is accurate for browser-visible updates, not for raw USB electrical polling. Use it to compare setups on the same computer and browser, not as a lab certificate. ### Why should I rotate a stick during the test? Many controllers are event-driven and report less often when nothing changes. Continuous stick movement keeps input changing so the browser can observe update frequency. ### Is 125 Hz Bluetooth normal? Yes. Many Bluetooth HID paths show around 125 Hz or variable readings in browsers. USB or a quality 2.4G receiver often reports higher and more stable values. ### Why does my 1000 Hz or 8000 Hz controller show a lower browser result? The page measures browser-visible Gamepad API updates, not the raw USB bus. High-Hz controllers can appear lower when the browser, driver, operating system, USB hub or power profile does not expose every hardware report to JavaScript. ### Are the benchmark rows live community submissions? Not yet. The table uses source-linked reference values from real controller models and reviews. Treat them as sanity ranges until a verified submission system is added. ### Can a web page measure real input lag? A web page can estimate update interval and browser-visible stability. It cannot measure the full chain from button press to game engine response to display output. ### Do I need 1000 Hz for games? Not always. A stable 250 Hz reading can already feel responsive for many games. Competitive shooters and fighting games may benefit from higher and more consistent update rates. ## Controller Latency Test Page: https://controllertestonline.com/controller-latency-test/ Source last updated: 2026-06-25 Use browser-visible polling and input updates to compare controller latency symptoms across USB, Bluetooth and 2.4G setups on the same system. A web page cannot measure end-to-end display latency like a hardware rig. It can still show update stability, dropped input patterns and polling differences between connection modes. For useful comparisons, test the same controller in the same browser, close heavy apps and repeat the sample after switching between USB, Bluetooth and adapters. ## Controller Vibration Test Page: https://controllertestonline.com/vibration-test/ Source last updated: 2026-09-23 Connect a controller, press any button, then run a short vibration test. Check weak and strong rumble and learn what the result means. Vibration depends on browser, operating system, controller model, connection mode and driver behavior. A controller can rumble in native games while still not exposing a compatible haptic actuator to the browser. ControllerTest checks browser-exposed haptic capability and sends short pulses through the Gamepad API path when available. It does not measure physical motor force, vibration latency or DualSense adaptive trigger resistance. ### How do I test my controller vibration online? Connect the controller by USB, press a physical button, then click Run quick vibration test above. If the browser accepts the short pulse, confirm whether you feel it. If you do not, compare another browser, connection mode and a game before assuming a hardware fault. ### Why does vibration show unsupported? The browser may not expose a compatible haptic actuator for this controller, OS, driver or connection mode. The controller can still rumble in native games. ### Does unsupported mean my controller motor is broken? No. Unsupported means this browser path cannot access a compatible haptic actuator. Compare USB, another browser, vendor software and a native game before assuming hardware failure. ### Why does my game vibrate but this page does not? Games can use native driver, console or platform APIs that expose rumble differently from the browser Gamepad API. ### Which browser works best for controller vibration? Chrome and Edge are usually the best first baseline for browser gamepad haptics, but support still depends on the controller, operating system and connection mode. ### Can this test DualSense adaptive triggers? No. The standard browser Gamepad API can read many inputs but does not provide normal control over DualSense adaptive trigger resistance. ### Can this measure real vibration strength? No. The page sends browser-exposed pulse values and lets you feel the result. It cannot measure physical motor force, vibration frequency or haptic latency. ### Will a short vibration test damage the controller? Normal short pulses should not damage a controller. Avoid long full-power loops if you are diagnosing an already faulty device. ### Why do weak and strong motors feel different? Many controllers use separate low-frequency and high-frequency rumble channels. One feels heavier, while the other feels sharper or lighter. ## PS Controller Calibration Guide Page: https://controllertestonline.com/ps-controller-calibration/ Source last updated: 2026-06-25 Use browser diagnostics to check whether a PlayStation controller shows drift, trigger range issues or deadzone symptoms before changing game settings. ControllerTest cannot write firmware settings or recalibrate a PlayStation controller. It can show browser-visible stick center, axis movement, trigger travel and vibration capability. Use those readings to decide whether to adjust in-game deadzone, try USB, clean the stick, run platform tools or seek repair. ## Interpreting reference data Controller reference tables on the HTML pages include source links and context. Manufacturer specifications and review figures are references, not measurements collected from the user's controller. Verify model, firmware, connection and platform against the linked source. For changing product specifications, use current manufacturer documentation. ## API references - [MDN Gamepad API](https://developer.mozilla.org/en-US/docs/Web/API/Gamepad_API) - [MDN vibrationActuator](https://developer.mozilla.org/en-US/docs/Web/API/Gamepad/vibrationActuator) ## Related guides - [tools.md](https://controllertestonline.com/tools.md) - [compatibility.md](https://controllertestonline.com/compatibility.md) - [pricing.md](https://controllertestonline.com/pricing.md) - [privacy.md](https://controllertestonline.com/privacy.md) - [Document index](https://controllertestonline.com/llms.txt) - [Complete guide](https://controllertestonline.com/llms-full.txt) --- Document: https://controllertestonline.com/compatibility.md # ControllerTest — compatibility and troubleshooting Canonical page: https://controllertestonline.com/support/ Language: English Last updated: 2026-10-08 Compatibility depends on the actual controller, connection, operating system, browser and driver. A device appearing here is not a guarantee that every input or haptic feature is supported. ## Compatibility notes ### Xbox / XInput controllers Browser result: Usually standard mapping Best first test is USB on Chrome, Edge or Firefox. ### DualSense / DualShock Browser result: Input support varies by OS Adaptive trigger resistance is not controlled by the standard browser Gamepad API. ### Switch Pro / Joy-Con Browser result: Mapping can vary Use the live input grid to confirm actual browser button labels. ### Vibration / haptics Browser result: Capability-detected Games may rumble even when the browser cannot expose a compatible actuator. ### Polling rate Browser result: Browser estimate Useful for comparisons, not a USB analyzer or hardware certification reading. Use this page when a controller does not appear, mappings look wrong, vibration is unavailable or a diagnostic result needs interpretation. ## Connection checklist Most browser controller problems start before the test data arrives. Work through the simple checks first, then rerun the live input test. - Connect the controller by USB for the first test, then compare Bluetooth or 2.4G later. - Press any controller button after loading the page to wake the browser Gamepad API. - Close games or launchers that may hold exclusive controller access. - Try Chrome, Edge and Firefox if one browser does not expose the device correctly. - Disconnect and reconnect the controller if the page still shows stale input. ## Interpreting common results A small stick center offset is normal. The important question is whether the offset is large enough to move a game character or camera when the stick is untouched. If a trigger never reaches the full range, test slowly several times. If the value remains capped, the issue may be hardware wear, driver mapping or platform-specific behavior. - Use stick drift for center noise. - Use circularity for outer-gate travel. - Use polling rate only for same-browser comparisons. - Use vibration results as capability detection, not proof that the controller motor is broken. ## Contact support Email support@controllertestonline.com with the controller model, operating system, browser name and version, connection mode and a copied health report.

This policy explains what the site does and does not collect. ## Local controller diagnostics The controller test reads Gamepad API input in your browser. Button states, stick values, trigger values, drift samples, circularity paths, reports, JSON, CSV and share cards are generated on your device. The v1 site does not create user accounts and does not intentionally upload controller diagnostic data to a server. ## Operational data Like most websites, hosting infrastructure may process basic request data such as IP address, URL, user agent, referrer and timestamps for security, debugging and delivery. ControllerTest uses Google Analytics 4 to understand aggregate page usage, language mix, browser classes, referrers and navigation patterns. GA4 is not used to upload controller diagnostic readings, exported reports or share-card data. ## Cookies and third parties The diagnostic tool does not require cookies to run. Google Analytics 4 may use cookies or similar storage for measurement. ControllerTest uses Google AdSense to display ads. Google and other third-party vendors may use cookies to serve ads based on a user's previous visits to this site or other websites. Users can manage or opt out of personalized advertising through Google Ads Settings at https://adssettings.google.com/. When a completed stick drift test finds high drift, the result can show Amazon links to Hall effect replacement sticks and controllers. As an Amazon Associate, ControllerTest earns from qualifying purchases. These links appear only after a test result, no diagnostic readings are sent to Amazon, and Amazon applies its own privacy policy and cookies after you click. External links, browser extensions, manufacturer software and third-party sites are governed by their own privacy policies. ## Contact and updates For privacy questions, contact support@controllertestonline.com. This policy may be updated when product features, hosting, analytics or advertising integrations change. The updated date on this page will reflect material revisions. ## AI assistant links Opening a footer AI link passes a preset public website question to the selected third-party service. The link does not include controller readings, reports, device identifiers or account data. Copying the prompt writes that same public question to the clipboard. If the user later pastes a diagnostic report into an AI service, that service's privacy terms apply. Footer interaction events record the selected guide or AI provider and website language in the existing analytics service, without controller diagnostic values or prompt text. ## Related guides - [tools.md](https://controllertestonline.com/tools.md) - [methodology.md](https://controllertestonline.com/methodology.md) - [compatibility.md](https://controllertestonline.com/compatibility.md) - [pricing.md](https://controllertestonline.com/pricing.md) - [Document index](https://controllertestonline.com/llms.txt) - [Complete guide](https://controllertestonline.com/llms-full.txt)
