Privacy Policy

Last updated: February 6, 2026

Overview

Undulate ("we", "our", "the app") is a breathing exercise app built with your privacy as a core principle. We do not collect, store, or transmit any personal data to external servers.

Data We Collect

We collect no personal data. Specifically:

No account creation required
No email addresses collected
No analytics or tracking SDKs
No advertising identifiers
No cookies or web beacons

Data Stored on Your Device

The app stores the following data locally on your device only:

Breathing session history - duration, mode, and cycles completed (stored in Core Data)
User preferences - haptic/sound settings, selected goal, reminder time (stored in UserDefaults)
Purchase status - whether you have unlocked premium (managed by Apple's StoreKit)

This data never leaves your device and is not accessible to us or any third party.

In-App Purchases

Premium features are purchased through Apple's App Store. All payment processing is handled entirely by Apple. We do not receive or store any payment information.

Third-Party Services

Undulate does not integrate any third-party analytics, advertising, or tracking services. The only external service used is Apple's StoreKit for in-app purchase verification.

Children's Privacy

Undulate does not knowingly collect information from children under 13. The app is suitable for all ages and requires no personal information to use.
