Privacy Policy

Lull · Last updated: July 3, 2026

Lull is built with your privacy at its core. This policy explains exactly what the app does — and does not — do with your information.

Data We Collect

None. Lull does not collect, transmit, sell, or share any personal data. We have no servers, no accounts, and no analytics or advertising trackers. Everything you do in Lull stays on your device.

Data Stored on Your Device

Your name, sleep sessions, sound preferences, and check-ins are saved locally on your device only. You can erase all of it at any time from Settings → Clear All Data.

Apple Health

If you choose to connect Apple Health, Lull requests permission to:

• Read your sleep analysis data, so it can show your real sleep insights (time asleep, awakenings, efficiency, and quality) inside the app.
• Write the sleep sessions you track with Lull back to Apple Health.

This data is processed entirely on your device and is never sent anywhere. Lull never uses Health data for advertising or shares it with third parties. You can revoke access anytime in the Apple Health app.

Children's Privacy

Lull does not collect data from anyone, including children.

Changes to This Policy

If this policy changes, the updated version will be posted on this page.
