Lullsky is a weather and sleep-sound app for iPhone. Your privacy matters. This policy explains what the app does with your information.
If you allow location, or search for a city, Lullsky sends coordinates or place names to Open-Meteo to fetch the forecast and air quality. We do not sell this data.
If you connect Apple Health, Lullsky reads last night’s sleep analysis on your device to show it on the Sleep tab. Sleep data stays on your iPhone. Lullsky does not write sleep data to Health.
Lullsky Plus subscription status is verified with Apple through StoreKit. We do not operate our own user accounts. Payment is handled entirely by Apple.
Lullsky uses Google Firebase (Analytics and Crashlytics) for stability and aggregate usage—such as installs, sessions, and crash stacks. There is no account, so this data is not tied to a login. It is not used for ads or cross-app tracking. Your city list, Health sleep, and sleep/sky audio stay on your iPhone and are not uploaded via Firebase. Processing follows the Google / Firebase privacy policy.
Lullsky is not directed at children under 13. We do not knowingly collect personal information from children.
We may update this policy. The “Last updated” date at the top will change when we do.
