Delete your account and data

How to delete your HanFlow PDF account and the data attached to it.

1. Delete it inside the app

Open the app and go to Settings → Account → Delete account. It is done as soon as you confirm.

2. Request it by email

From the address you signed up with, email info@qmscience.net with the subject "Account deletion request". We complete it and reply within 5 business days.

What is deleted

Your password and your sign-in tokens (sessions). After deletion you can no longer sign in with that account.

What is kept, and why

Purchase and licence records are kept for 5 years as required by consumer-protection law. Deleting them would make refunds and re-issuing impossible. A single line holding your sign-up email address remains, only as a marker so that a deleted account cannot be revived. Device registration (activation) records are kept for the same reason.

What about your documents

The app does not send your documents to a server — all work happens on your device. There is one exception: “Send to my device” in the PC edition. If you use it, that document is held on our server under a 6-digit code for up to 24 hours and is then deleted automatically.
