SleepCalculator is a sleep optimization app for iOS that helps users calculate the best time to go to bed or wake up based on natural sleep cycles.
This privacy policy applies to the iOS main app itself, its embedded frameworks, and any official app extensions or examples provided. It does not apply to personal data or input that users manually add.
In short, the SleepCalculator app does not collect any personal data from you.
Your input (such as selected wake-up times or bedtime preferences) is processed locally on your device. We do not store, transmit, or access any of your personal or usage data.
Please be confident in using our service — your information stays entirely on your device. We do not track you, and we do not collect analytics or share any data.
Cookies are small files often used to store anonymous information in web browsers. SleepCalculator does not use cookies or any similar tracking technologies.
We may update our Privacy Policy from time to time. You are advised to check this page periodically for updates. Any changes will be posted here and will take effect immediately upon posting.
