Purpose
PumpSync syncs your pump data to Apple Health when you request a sync and, after initial setup, automatically checks for any pump data not yet synced when the app opens and during iOS background refresh opportunities. It aims to keep Apple Health less than four hours behind, but iOS may delay background work. PumpSync is intended for personal data portability and recordkeeping.
Not medical advice
PumpSync is not a medical device. PumpSync does not provide medical advice, diagnosis, treatment, or dosing recommendations.
PumpSync output may be incomplete, delayed, duplicated, or inaccurate. Users are responsible for verifying health data and making medical decisions with qualified healthcare professionals.
User responsibilities
Users are responsible for:
- using PumpSync only with accounts and devices they are authorized to access;
- keeping App Store, Tandem, device, and self-hosted backend credentials secure;
- reviewing Apple Health data for accuracy after sync;
- complying with Tandem, Apple, and other applicable third-party terms;
- stopping use of PumpSync if it behaves unexpectedly or appears to produce inaccurate data.
Tandem Source access
PumpSync is not affiliated with, endorsed by, or sponsored by Tandem Diabetes Care. Tandem Source availability, authentication, rate limits, and data formats may change without notice. PumpSync may stop working if Tandem changes its services or terms.
Apple Health
PumpSync writes data to Apple Health only after the user grants permission. Apple Health permissions and stored Health records are managed through Apple; see Apple Support: view and delete Health data.
Account and data deletion
Users may remove Tandem credentials in the app. Users may request deletion of subscription and installation metadata stored by the PumpSync-hosted backend using the account and data deletion instructions.
Acceptable use
Users may not use PumpSync to access another person's data without authorization, interfere with PumpSync services, bypass rate limits, reverse engineer service protections, or use PumpSync for unlawful purposes.
Availability
PumpSync may be unavailable, delayed, or discontinued. Beta and TestFlight builds may be reset or changed without notice.
Limitation of liability
To the maximum extent permitted by law, PumpSync is provided as-is and without warranties. PumpSync's developer is not liable for indirect, incidental, consequential, special, exemplary, or punitive damages, or for medical, health, data loss, service interruption, or third-party service issues arising from use of PumpSync.
Some jurisdictions do not allow certain warranty exclusions or liability limitations, so some terms may not apply.
Changes
These terms may be updated as PumpSync changes. Continued use after an update means the user accepts the updated terms.
