Delete your data

Last updated: November 9, 2026

This English version is provided for convenience. In case of any discrepancy, the German version (Daten löschen) prevails.

This page explains which data is created when you use Kartenscan and how you can delete it. The Kartenscan app is developed by MARCODES GmbH.

Is there an account?

Kartenscan works without signing in. On first start, the app creates an anonymous device account without an email address so that your collection, lists and notifications can be stored. Optionally, you can sign in with your email address or your Google account, for example to back up your collection or use it on several devices.

Delete your account

There are three ways. Each deletes your account immediately and permanently, there is no recycle bin and no waiting period:

  1. In the app: "Profile", then "Delete account". This also works for a device account without sign-in.
  2. Here on this page with a code we send to the email address of your account:

The form needs JavaScript. Without JavaScript, delete your account in the app or by email (see below).

Code sent to

The code is valid for 15 minutes. No email? Please also check your spam folder.

Done

If the app is still installed, it creates a new, empty device account the next time it starts.

  1. By email to contact@kartenscan.com from the email address of your account. We usually delete within a few days, at the latest within one month, and confirm the deletion.

Request deletion by email

A device account without sign-in has no email address. You delete it in the app or by uninstalling the app. On our server, a device account that is no longer used is deleted automatically after 365 days without use.

What is deleted

  • profile, email address, linked Google account, age information and, if applicable, parental consent,
  • collection, wishlist, watchlist, saved searches,
  • notifications, notification settings and push tokens of your devices, signed-in devices and sessions,
  • in the Kartenbörse: your profile, your listings including photos, your ratings and blocks.

What remains, without any link to you

  • Kartenbörse chats: Conversations remain for the people you talked to. The content of your messages is removed and shown as "deleted", your pseudonym appears as "deleted user".
  • Reported sales: If you reported a sale price, the price remains as an anonymous data point in the price statistics. The link to your account and any proof link are removed.
  • Clicks on offer links: remain counted for settling accounts with the partner programmes, the link to your account and your installation is removed.
  • Reports you submitted in the Kartenbörse remain for ongoing reviews without any link to your account.
  • Data we have to keep for legal reasons, for example to investigate a reported violation of the law.

Data on your device

Settings and cached data of the app are stored on your device. To delete them:

  1. Open the Android settings, then "Apps" and "Kartenscan".
  2. Choose "Storage" and tap "Clear data".

Alternatively, uninstall the app. This removes all local data. An account with sign-in remains on the server until you delete it.

Other data on our server

  • Card photos: images you scan for identification are not stored after identification. There is nothing to delete.
  • Server log files with IP address and time are deleted automatically after 14 days.
  • Emails and beta waitlist: if you wrote to us or joined the beta waitlist, we delete your email address and messages on request, except for data we have to keep for legal reasons.

Download your data

Before deleting, you can download all data of your account as a file in the app under "Profile" and "My data" (Art. 15 and 20 GDPR).
