Privacy policy

PeakNits website (peaknits.net), including the Display Test, and the PeakNits Chrome extension · Last updated: 8 November 2026

In short: PeakNits does not collect, store or send any personal data. All audio analysis, rendering and test results stay on your device. The website counts visits in aggregate, without cookies, and only if you allow it (see Statistics).

Audio

• PeakNits analyzes audio only to draw the visualization. Audio is processed in real time in your browser (Web Audio API) and is never recorded, stored or transmitted anywhere.
• The extension captures the audio of a tab only after you click the PeakNits toolbar icon on that tab (tabCapture permission). Chrome shows a capture indicator on the tab while this is active. Capturing stops when you close the visualizer, close the tab or click the icon on another tab.
• The website can use your microphone, an audio input or a shared tab only after you choose that source and grant permission in the browser. You can revoke these permissions at any time in your browser settings.

Tab information

When you click the toolbar icon, the extension reads the title of that tab only to show it as the current source inside the visualizer. It is not stored or sent anywhere.

Settings

Your visual settings (mode, palette, line width and similar) and the last used audio source type are saved in your browser's local storage on your device, so they are there next time. They never leave your device. You can clear them with “Reset to defaults” in the app or by clearing site data in your browser.

The Display Test saves your last report – one for the full test and one for each single test, such as the dead pixel test – (your answers, the results and the detected display details such as resolution, refresh rate, HDR state and browser) and the optional values you enter (such as the Windows SDR brightness slider or a colorimeter reading) in your browser's local storage, so you can open the report again later. Display detection and the PDF report are made on your device; nothing is sent to PeakNits. Clearing site data in your browser removes them.

Statistics

To know how many people use PeakNits and which pages they open, the website can use Cloudflare Web Analytics – only if you allow it. On your first visit a small prompt asks you; until you click “Allow”, the statistics script is not loaded at all. If you allow it, it counts page views in aggregate – the page, the referring site, the country, the browser and device type, and how fast the page loaded – without cookies, without storing anything on your device and without identifiers that follow you between visits or sites. PeakNits sees only totals, never individual visitors. Your choice is saved in your browser's local storage. Statistics are never collected in the visualizer or in the Chrome extension.

No tracking

• No advertising, no cookies, no accounts, and no analytics other than the optional cookieless statistics above.
• The extension contains all of its code and does not load remote code.
• The website is served by Cloudflare. Like any web host, Cloudflare processes technical request data (such as IP addresses) to deliver and protect the site. PeakNits only looks at aggregate totals derived from it (such as the number of requests per day and per country) and does not use it for any other purpose.

Changes

If this policy changes, the updated version will be published on this page with a new date.
