Privacy

Last updated 2 October 2026.

What is collected

Your email address, a display name, and whatever you put in: tanks, rooms, what lives in them, and your logs. Nothing else is gathered about you.

Why

To run your account and show you your own data. Your email is used to confirm the account and to reset your password. Nothing is sent to you that you did not ask for.

Who else sees it

Nobody, unless you publish a tank yourself, which is off by default and reversible. Your private notes are never on a public page. Your data is not sold, shared, or used to train anything.

Where it lives

On a single server in Germany, run by Hetzner. Email is sent through Resend. There is no analytics or advertising code on this site, and no cookies beyond the two that keep you signed in.

Your data is yours

You can download everything at any time from settings, as one file. You can delete your account from the same page, which removes it and everything in it for good.
