Privacy policy
Last updated 1 November 2026

- What you press stays in your browser. It's never stored or sent anywhere.
- Google shows ads here and uses cookies for them, subject to your choices where consent is required.

Your keys, clicks and other inputs
The test shows your inputs on the page and nothing more. Keys, shortcuts, clicks, scrolling, mouse movement, touch, gamepad buttons and pasted content are not saved, sent to us or shared with anyone. The list clears each time you start a test. Analytics do not record how many inputs you made.
Ads from Google AdSense
Google, through Google Ireland Limited in the EEA, UK and Switzerland, shows ads on this site. Google and its ad partners may use cookies and similar technologies to show and measure ads, limit how often you see them and prevent fraud. They may use your IP address, device and browser details, the pages you visit and your approximate location. If you agree, they may also personalize ads based on your interests and precise location data.
In the EEA, UK and Switzerland, a Google consent message asks for your choice first. The legal basis is your consent (GDPR Article 6(1)(a)), and some ad partners may rely on legitimate interests (Article 6(1)(f)), which you can object to in the same message. Saying no doesn't stop you using the test.
You can also manage personalized ads in Google's My Ad Center, delete cookies in your browser and read how Google uses data from sites that use its services. The list of ad partners is available from the consent message.
Analytics from PostHog
We use PostHog to see how the site is used and how ads perform. It runs in cookieless mode, so it stores nothing on your device, and recording of clicks and sessions is turned off. Data goes through an address we set up for PostHog, blueberry.tomapli.cz, to its EU cloud service.
PostHog receives:
- Pages viewed and when you leave them, and the address you came from
- When a test starts and finishes, and how long it lasted
- Whether the ad script loaded, and whether each ad slot was filled
- Your browser, operating system, device type, screen size and language
- Your IP address, used to estimate your approximate location and, with your browser details, to build an anonymous visitor ID that changes daily
The legal basis is our legitimate interest in understanding and improving the site and its ad income (GDPR Article 6(1)(f)). You can object at any time by emailing us. We keep this data for up to 2 years.
Hosting by Cloudflare
Cloudflare delivers and protects this site. To do that it processes technical request data such as your IP address, the page requested, and your browser details. The legal basis is our legitimate interest in running a secure site (GDPR Article 6(1)(f)). Cloudflare keeps these logs for a limited time under its privacy policy.
Who receives your data
- Google and, where you allow it, its ad partners
- PostHog, Inc.
- Cloudflare, Inc.
We don't sell your data. Some of these companies are based in the United States or use providers outside the EEA, so data may be transferred there. These transfers rely on the EU-US Data Privacy Framework where the company is certified, or on the European Commission's standard contractual clauses.
We don't make decisions about you that have legal or similarly significant effects by automated means. Ad personalization, where you allow it, involves profiling by Google and its partners.
Your rights
Under the GDPR you can ask us for access to your data and for it to be corrected, deleted, restricted or transferred, and you can object to processing based on legitimate interests. Where processing is based on consent, you can withdraw it at any time, without affecting what happened before. To use these rights, email privacy@catchallinputs.com. Because we don't ask who you are, we may be unable to link analytics data to you.
You can complain to a data protection authority. In the Czech Republic that is the Office for Personal Data Protection (ÚOOÚ).
You don't have to provide any data to us, and the site has no accounts. Blocking cookies or ads won't stop the test from working. This site isn't aimed at children under 15.
