LGTM. counts what players do so we can make the game better: which buttons get pressed, how far people get, where they stop. That data is anonymous. Your browser gets a random id; we do not store your IP address, user agent, cookies or anything that points to you. If your browser sends Do Not Track or Global Privacy Control, nothing is recorded.
If you save your game with an email, we keep that address and your save. We use the address to send the save link and, only if you ticked the box, one email when the next chapter ships. Every email has a link to unsubscribe or delete your save and address.
Emails are sent through Resend. The app and its database run on Heroku.
