Privacy
A short version of this policy: your calculator inputs never leave your browser. Here's the rest of it.
What we don't collect
Every calculation on TinyTests runs in your browser. When you enter an income or run the reaction-time test, that number is never uploaded or sent to a server — we have no way to see it. There are no accounts, no sign-ups, and no forms that submit your data anywhere.
Hosting
The site is served by Cloudflare Pages. Like any host, Cloudflare may process standard request logs — things like IP address and user agent — as part of delivering the pages to you. We don't separately collect or store this.
Analytics
We use Cloudflare Web Analytics to see how many people visit the site. It's cookieless, doesn't fingerprint you, and doesn't track you across other sites — it just counts page views in aggregate.
Advertising
TinyTests doesn't run ads today. If we introduce advertising, it would be through Google AdSense, which uses cookies — including from third-party vendors — to serve and measure ads. You'd be able to read more and adjust your settings at Google's ads policy page and Ad Settings. We'll update this page if that changes.

Questions about this policy or the site can go through the GitHub repository.
