Welcome to Sleep Calculator, a free Android app developed by Zaheer Afzal. At Sleep Calculator, your privacy and trust are incredibly important to us. This Privacy Policy outlines the information we collect, how we use it, and the measures we take to ensure your privacy while using our app.
Introduction
Sleep Calculator is designed to help you calculate ideal bedtimes and wake-up times based on your sleep cycles. Our goal is to provide you with a helpful, easy-to-use tool for improving your sleep routine. Rest assured, we are committed to protecting your privacy while you use the app.
Information We Collect
When you use the Sleep Calculator app, we want to assure you that we do not collect any personal or sensitive data directly. The app operates offline and does not require any user accounts or login information.
Permissions We Request
Although Sleep Calculator does not collect personal data, it may request permission to access certain features of your device. These permissions include:
-
Storage Access: This allows the app to save user preferences and settings (like time format).
-
Internet Access: To display links to external websites (such as the Wikipedia page about sleep cycles) and to serve ads via Google AdMob.
AdMob Data Collection (Google Ad Services)
Sleep Calculator uses Google AdMob to display advertisements. AdMob may collect certain non-personal information to provide relevant ads and improve ad performance. This may include:
- Advertising ID: A unique, user-resettable identifier used for personalized advertising (you can opt out in your device settings).
- Device Information: Non-identifiable data such as device model, operating system, and general location (country-level).
- Ad Interaction Data: Information about how you interact with ads (e.g., clicks, impressions).
For more details, please review Google’s Privacy Policy.
How We Use Your Data
Since no personal information is collected by the app itself, we do not store or share your data with third parties. Sleep Calculator functions offline and operates solely based on the inputs you provide (such as your desired wake-up time or bedtime).
AdMob uses collected data to:
- Display relevant ads based on general interests.
- Measure ad performance and prevent fraud.
Third-Party Services
While Sleep Calculator does not integrate third-party services for functionality, the app may contain links to external websites, such as educational resources related to sleep. Additionally, Google AdMob serves ads and may collect data as described above.

Advertising
Sleep Calculator is a free app supported by ads via Google AdMob. These ads help us keep the app free while maintaining a respectful user experience. You may see:
- Non-personalized ads: Based on general factors like app content.
- Personalized ads: If enabled via your device’s Advertising ID (you can opt out anytime in settings).
Data Retention and Security
Since the app doesn’t collect any personal information, there is no data retention on our end. We do not store your wake-up time or other details. The app operates purely on-device with no external data processing.
AdMob retains anonymized ad-related data as per Google’s policies.
How We Protect Your Information
Although Sleep Calculator does not handle sensitive data, we take all reasonable steps to ensure that the app is secure and operates without errors. Since no personal information is collected directly, the risk of data misuse or unauthorized access is minimal.
Children’s Privacy
Sleep Calculator is not designed for children under the age of 13, and we do not knowingly collect any information from children. AdMob complies with Google’s policies regarding child-directed content and does not serve personalized ads to users under 16.
