Privacy Policy
Last Updated: April 17, 2026
At Sleep Effect, we are committed to protecting your privacy. This policy explains how we handle your information when you use our mobile application.
1. Information We Collect
Sleep Effect does not collect, store, or share any personally identifiable information (PII). We do not require an account, email address, or phone number to use the app.
2. Anonymous Usage Data
We use Firebase Analytics to help us understand how users interact with the app. This data is strictly anonymous and aggregated. We track events such as:
- Which sound tracks are started/stopped.
- When a custom mix is saved.
- How often the sleep timer is used.
This information helps us improve the app and prioritize new feature development. It cannot be used to identify you personally.
3. Crash Reporting
We use Firebase Crashlytics to receive anonymous technical reports if the app crashes. This includes device model, OS version, and the technical logs at the time of the crash. This is used solely for fixing bugs and improving stability.
4. Children's Privacy
Our app does not target or knowingly collect data from children under the age of 13. Since we do not collect any personal data, we fulfill the requirements of COPPA and GDPR regarding children's privacy.
5. Data Security
Because we do not collect personal data, there is no risk of your identity being compromised through our app. Any anonymous data collected via Firebase is subject to Google's world-class security standards.
6. Changes to This Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date.
