Account and Data Deletion

PumpSync stores minimal hosted subscription and installation metadata and does not persist Tandem credentials, Tandem tokens, raw Tandem events, or normalized Tandem samples on the backend.

Effective date

June 18, 2026

Delete Tandem credentials from the device

In the PumpSync app:

  1. Open Settings.
  2. Open the Tandem section.
  3. Delete the saved Tandem credentials.

Deleting Tandem credentials prevents future syncs until credentials are added again.

Revoke Apple Health access

On your device:

  1. Open Settings.
  2. Open Health.
  3. Open Data Access & Devices.
  4. Select PumpSync.
  5. Disable PumpSync access or remove PumpSync data as desired.

Samples already written to Apple Health are controlled by Apple Health. Deleting PumpSync does not automatically delete samples already written to Apple Health.

Delete PumpSync Hosted metadata

The preferred way to request deletion is from the PumpSync app:

  1. Open PumpSync.
  2. Open Settings.
  3. Open Data Handling.
  4. Tap Delete Data Request.
  5. Send the prefilled email.

The app includes the PumpSync installation ID needed to locate hosted metadata associated with that app install.

If you cannot send the request from the app, email support@ericslutz.dev with the subject DELETION REQUEST - PumpSync Support.

Include your PumpSync installation ID. To find it in the app, open Settings, then Developer, then copy the Installation ID.

Do not include Tandem passwords, Tandem tokens, screenshots containing health data, or other sensitive medical details in the request.

Deletion covers PumpSync hosted server-side metadata associated with the subscription or installation, subject to records PumpSync must retain for security, fraud prevention, legal compliance, billing, dispute handling, or service integrity.

Self-hosted users

Self-hosted users control their own backend data and should delete data directly from their self-hosted storage account or database.

Nonprod and TestFlight data

For nonprod and TestFlight builds, PumpSync may reset backend data during testing. Testers can request deletion using the same support path above.
