The short version
The tests on this site run inside your browser. Your camera picture, microphone sound, key presses, mouse movement, files, location and sensor readings are processed on your device and are never sent to this site or anyone else. There are no accounts, no analytics and no ads.
Data the tests use
When a test asks for your camera, microphone, location, Bluetooth, USB, serial, MIDI or file access, your browser asks you first, and you can say no. The test uses the data in the open tab only. Recordings and photos are kept in your browser's memory until you download them or close the tab. Files you choose for a storage speed test are written, read and then deleted on your own drive.
Data stored on your device
Some tests remember small preferences in your browser's local storage, such as the last camera you chose, a volume level or your best score. This stays on your device. You can clear it at any time in your browser's settings under site data. The site sets no cookies for visitors. The only cookie it uses is a sign-in cookie for the site's own admin area, which visitors never receive.
Hosting
This site is served through Cloudflare, which handles technical data such as IP addresses and browser details to deliver pages and to protect the site from attacks. Cloudflare may set a short-lived security cookie to tell people from bots. See the Cloudflare privacy policy for how Cloudflare handles that data.
Contact form
If you send a message, your name, email address and message are stored so it can be answered, together with the country your connection comes from and your browser's name and version, which help when a test does not work on your device. To stop spam, a one-way scrambled form of your IP address is kept for up to an hour to count how many messages it has sent; the address itself is not stored. Messages are not shared or sold, and they are deleted once they are no longer needed. You can ask to see or delete your message through the contact form.
Advertising
There are no ads on this site at the moment. If ads are added later, this policy will be updated before they appear and will name the ad networks used. With Google AdSense, for example, third party vendors including Google use cookies to serve ads based on a visitor's previous visits to this and other websites, and anyone can opt out of personalized advertising in Google Ads Settings or opt out of some other vendors' cookies at aboutads.info. Visitors in the UK, the European Economic Area and Switzerland would be asked for their consent before any advertising cookies are set.
Your rights
You can ask to see the message you sent, have it corrected or have it deleted. If you are in the UK or the European Economic Area, you also have the right to complain to your data protection authority, such as the Information Commissioner's Office in the UK. Messages are kept on the basis of a legitimate interest in answering them.
Children
This site is not directed at children under 13 and does not knowingly collect personal information from them.
Changes
If this policy changes, the date at the top of this page changes too.
