account deletion
Delete your Markerra account
You can delete your Markerra account directly in the app or request deletion by email if you no longer have the app or cannot sign in.

The data controller is Przemysław Wiśniewski Digital, a sole proprietorship registered in CEIDG, NIP: 5243019522, REGON: 529876286, address: ul. Turmoncka 22/1103, 03-254 Warsaw, Poland.
The fastest path is deleting the account in the app, because the process is automated and tied to the logged-in user. If you do not have access to the app, you can send an account deletion request by email.
What will be deleted
Account deletion removes the Markerra app account and Markerra app data linked to the user: route progress, scan attempts, rewards, and analytics events, except data that we must keep for a limited time for security, complaint handling, or accountability. This operation cannot be undone.
If a deployment issues reward codes, we may keep a minimal pseudonymous reward claim until the end of the deployment retention period. It does not contain the plain email address, but it lets us prevent multiple code redemptions through deleting and recreating an account.
Aggregated or anonymised data that cannot be linked to the user may remain in deployment reports and summaries.
Delete the account in the app
- Open the Markerra app.
- Go to the account screen.
- Select “Delete account”.
- Confirm deletion. The app will return to the login screen when the operation is complete.
Delete the account without the app
If you no longer have the app or cannot sign in, send an account deletion request to: [email protected].
- If possible, send the message from the email address used to sign in to Markerra.
- Use the subject “Markerra account deletion”.
- Include whether the account used Google or Apple sign-in and the deployment name, if you remember it.
Before deleting the account, we may ask for additional confirmation so we do not delete the wrong account.
Deletion timing
In-app account deletion is performed after the logged-in user confirms the action. Email requests are handled after we confirm that they refer to the correct account. If the in-app operation fails because of a temporary technical issue, refresh the app data or use the email request path. We complete requests without undue delay and generally no later than one month after receiving a verified request. For complex cases, this period may be extended by two additional months; we will inform the user within the first month and explain the reason for the extension.
