Privacy

Short version: this site collects almost nothing, and what it does collect stays here.

No accounts, no tracking

You can use every part of this site without signing up or logging in. There are no advertising networks, no third-party analytics scripts, no social media pixels and no cookies set by this site. Your streak and score live only in your browser's memory for the current visit and are never sent anywhere.

The waitlist email

If you join the premium waitlist, I store the email address you enter and the page you entered it on. That is the whole record. I will use it to send one launch announcement. I will not sell it, share it, or add it to any other list, and any waitlist email will include a way to be removed. To be removed sooner, write to [email protected].

Hosting

The site is served by Cloudflare, which, like any host, sees requests at the network level (IP address, requested page) and applies its own privacy policy. I do not run analytics on top of that and I do not see individual visitors.

Email you send me

If you email a correction or question, I keep the thread so I can reply and fix things. Nothing more is done with it.

Changes
