FAQ

What does PumpSync do?

PumpSync syncs Tandem Source pump data to Apple Health at the user's request, including insulin and carbohydrate samples when supported by the current sync flow.

Do I need PumpSync Hosted?

No. PumpSync supports a hosted subscription path and a self-hosted path where you point the app at a backend you operate.

Where are Tandem credentials stored?

The app stores Tandem credentials in Keychain with device-only accessibility. Credentials are sent to the backend only during an active HTTPS sync request.

Does PumpSync keep my Tandem health data on the backend?

No. The backend does not persist Tandem credentials, Tandem tokens, raw Tandem events, or normalized Tandem samples.

How do I remove data?

See the data deletion page for Tandem credential removal, Apple Health access revocation, hosted metadata deletion, and self-hosted deletion guidance.

Is PumpSync medical advice?

No. PumpSync is not a medical device and does not provide medical advice, diagnosis, treatment, or dosing recommendations.
