Period Calendar Period Tracker

"To support and maintain Our Service, We may involve Google to provide You with personalized ads. Google may collect certain Personal Data (online identifier and ip address) for advertising, analytics, and fraud prevention purposes."

The app shares user data (online identifiers and IP addresses) with Google AdMob for personalized advertising, analytics, and fraud prevention, even though the policy claims not to collect personal data itself.

"However, when You use the Service, third-party advertising companies may display interest-based advertising (also called online behavioral advertising) using information collected about your online activities over time across multiple websites, Applications, and other online Service sites."

Third-party advertising companies embedded in the app track user activity across multiple websites, apps, and online services over time to build behavioral advertising profiles.

"If You want to send feedback to Us to improve your using experience, We may collect your usage data, like theme type, App Version, system version, screen size, language, country, app language, Device, notification access, time zone, network, apple watch connection, account, and whether you subscribed, removed the ads."

When sending feedback, the app collects a broad range of device and usage data including notification access status, network info, and connected device details, which goes beyond what's needed for a calendar/period tracker.

"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. We will let You know via a prominent notice on Our Service prior to the change becoming effective and update the "Last Updated" date at the top of this Privacy Policy. Changes to this Privacy Policy are effective when they are posted on this page."

The company can change the privacy policy at any time, and changes take effect immediately upon posting. While they promise a prominent notice, continued use constitutes acceptance with no opt-in required.
