In the app: open the Account screen and choose "Delete account". This removes the account, its e-mail sign-in, its shopping lists, favorites and price alerts. The device is detached from the account and keeps working anonymously; the one-time login codes for your e-mail are deleted too.
By e-mail: write to connect@shkelik.com from the address you signed in with and ask to delete your account. We will delete it within 30 days.
Not signed in? Without an account your lists, favorites and search history are only on your phone: delete the app to remove them. The server keeps only a random device ID; to have it deleted, write to connect@shkelik.com.
Retention. Technical logs are kept for a limited time for security and are not linked to your account.
