Data Deletion
Last updated: April 2026
Before You Delete — Download a Copy
Deletion is permanent. If you want to keep a portable copy of your data — events, streams, attachments, audit log, and more — use the self-service download tool first: Download All My Data.
The tool produces a series of ZIP files in an open, machine-readable format you can keep, archive, or forward to another service.
How to Delete Your Account
If you wish to delete your Health Data Safe account and all associated data, send a deletion request by email to:
Please include the username or email address associated with your account. We will process your request within 7 business days and confirm by email once complete.
Selective Data Management
You can also selectively delete or modify most of the data stored on HDS directly from the web application, the iOS app, or the Android app, without deleting your entire account. This includes individual health entries, diary records, connections, and data streams.
What Data Is Deleted
When your account is deleted, the following data is permanently removed:
- Your user profile (username, email, display name, avatar)
- All health data stored in your account (events, measurements, diary entries)
- All data streams and their structure
- All app connections and access permissions
- Push notification device tokens
What Data May Be Retained
- Backup copies, data in backup storage may persist for up to 30 days after deletion, after which it is permanently purged.
- Data shared with third parties, if you previously shared data with a healthcare professional or other user, their copy of the shared data is not affected by your account deletion. You should contact them directly to request removal.
- Anonymized analytics, aggregated, non-identifiable usage metrics (e.g., feature usage counts) are not deleted, as they cannot be linked back to your account.
Our Commitment

In the event of the Foundation’s dissolution, all personal data must be destroyed — after giving users and authorized researchers the opportunity to download it — or migrated to a service offering similar guarantees.
