Lull: Sleep Aid & Fan ("App", "we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains our data practices when you use the App. By using the App, you consent to our collection and use of information as described here.
Lull does not collect, store, or transmit:
The App includes third-party services that may collect data:
When ads are displayed in the free version of the App, Google may collect:
This data is used to show you more relevant ads and measure ad performance. You can opt out of personalized advertising in your device's privacy settings, and you can disable personalized ads by purchasing the "Remove Ads" or "Pro" product.
For details on Google's data practices, see Google's Privacy Policy.
The App stores the following locally on your device:
All of this data stays on your device and is never transmitted to our servers.
The App periodically fetches an updated list of fan sounds from our servers. This fetch includes no personal data—only a request for the catalog manifest file. The servers log which IP addresses fetch the catalog (standard web server logs), but these are not tied to you personally.
We do not sell, rent, or share your personal information with third parties for marketing purposes. The only data shared is with Google AdMob for advertising (IDFA and app usage only, if you granted tracking permission). All other data is kept local to your device.
Data stored on your device persists until you delete the App. Web server logs (standard HTTP logs from catalog fetches) are retained for standard periods (typically 7–30 days depending on server configuration) and are not tied to any personal identifier.
We employ reasonable security measures to protect data transmitted over the network (HTTPS for catalog fetches). However, no method of transmission or storage is 100% secure. We cannot guarantee absolute security of any data transmitted over the internet.
Depending on your jurisdiction, you may have the right to:
Since we collect very little data and do not maintain user accounts, most of this is managed through your device settings or by contacting us directly.
The App is not directed to children under 13 (or the equivalent age in your jurisdiction). We do not knowingly collect data from children under 13. If we learn we have collected data from a child under 13, we will delete it promptly.
When you first use the App, iOS will ask for permission to track your activity across other apps and websites. This permission controls whether your IDFA is shared with Google AdMob for personalized advertising. You can change this setting at any time in Settings → Privacy → Tracking.
If you are a California resident, you have the right to know what personal information is collected, used, shared, or sold. Since Lull does not sell data and collects minimal personal information, your main rights center on:
We may update this Privacy Policy at any time. Changes are effective immediately upon posting. Your continued use of the App means you accept the updated policy.
If you have questions about this Privacy Policy, how we handle your data, or to exercise your privacy rights, contact us at davit.ghushchyan@gmail.com, or visit our Support page.

We aim to respond to privacy inquiries within 30 days. Given the minimal data collection in this App, most inquiries can be resolved quickly.
