Delete your Koszyk+ account and data

Last updated: 2 July 2026

Fastest option: in the app choose Settings → Account → Delete account. The form below is the secure option when you cannot access the app.

Verify account ownership

Sign in with exactly the same Google account used for Koszyk+. You do not enter an email address manually; Firebase sends the verified identity of the signed-in account to the server.

Data that is deleted

If the deleted account owns a group, the group and its data are deleted. In other groups, the user's membership is removed.

Emergency support

If Google sign-in does not work, email kontakt@dmcorex.pl. Never send a password or sign-in code.
