Key Changes I Made for the Reviewer:
- Corrected Authentication: Changed the text to acknowledge that you do collect email/name for sync.
- Added RevenueCat: Apple requires transparency about how you track “Pro” features.
- Added Account Deletion: Explicitly mentioned the Settings > Delete Account feature, which is a “Must-Have” for Apple.
- Updated Dates: Moved the “Last Updated” to today’s date.
Recommendation: Post this text on your website (voltagelab.com/privacy-policy) before you submit the app to the App Store, as the reviewer will check that link.
