Delete your data

Last updated: 6 October 2026

FastDoc QES has no user account and stores no data with us. All of the app's data is on your device. Here is what is stored and how to delete it.

What the app stores

Encrypted in the device's protected storage (iOS Keychain or Android Keystore):

Your CAN
Your handwritten drawing for the stamp, if you created one
The name, title, profession and certificate from your eHBA

In the app's storage:

the signing log (time, document checksum, certificate serial number, result) and a copy of your signing certificate
settings: trial signature counter, subscription status, time you accepted the terms, chosen output folder

Your PIN is never stored. Signed PDFs are in the folder you chose; they belong to you and are not deleted by the app.

Deleting in the app

Under "Mein Profil" (My profile) you can remove these items individually at any time:

"Gespeicherte CAN löschen" (delete stored CAN)
"Gespeicherte Zeichnung entfernen" (remove stored drawing)
"Ordner entfernen" (remove the output folder for signed PDFs)

Deleting all data

Android

Open Settings › Apps › FastDoc QES › Storage and tap "Clear data", or uninstall the app. This removes all the data listed above.

iPhone and iPad

First delete the stored CAN and drawing in the app under "Mein Profil".
Then touch and hold the FastDoc QES icon on the Home Screen, tap "Remove App", then "Delete App".

When the app is deleted, iOS removes the signing log, the certificate copy and the settings. However, iOS keeps Keychain entries even after an app is deleted, and the app reuses them if you install it again. That is why you should delete the CAN and drawing in the app first. The name, title, profession and certificate from your eHBA cannot currently be deleted in the app. They never leave your device and are removed when you reset the device (Settings › General › Transfer or Reset iPhone › Erase All Content and Settings).

Device backups

If you use iCloud Backup or Google backup, app data may be contained in older backups. You manage these in the settings of your device or your Apple or Google account.

Subscription

Deleting the app does not cancel a subscription. Cancel it in your store's subscription settings. Purchase records are kept by Apple or Google; their deletion is governed by the respective store's privacy policy.

Data held by us

We only hold data you sent us yourself, such as support emails. You can ask us to delete it at any time at [email protected]. We reply within one month.

Attrian account (coming soon)

The announced practice connection will require an Attrian account. Once it is available, this page will explain how to delete the account and its data in the app and by email.
