GROW Fitness App – Privacy Policy
Effective Date: May 8, 2025
Thank you for choosing GROW ("GROW", "we", "our", or "us"). Your privacy is important to us. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use the GROW iOS and watchOS applications, related services, and any other software or tools we provide (collectively, the "App").

We are not required to appoint a Data Protection Officer because, as a micro‑entity, we do not process health data on a large scale. Should this change, we will update this Policy accordingly.
2. Scope of This Policy
This Policy applies to all users of the App worldwide. Because we are established in the European Union, the EU General Data Protection Regulation (GDPR) governs our processing of personal data. Users outside the EU may have additional rights under local laws.
