Posy is a privacy-first period tracker designed with your privacy as the top priority. Your health and cycle data never leaves your device. However, Posy displays ads powered by Google AdMob, which may collect certain non-health data as described below.
We do NOT collect, store, or transmit any of your personal health data. All cycle data, logs, and settings are stored locally on your device only. We have no servers, and we cannot access your information.
Posy uses Google AdMob to display advertisements. AdMob may collect the following data to serve and measure ads:
If you deny tracking consent in the ATT prompt, AdMob will serve non-personalized ads and will not access your IDFA.
Google's data collection is governed by the Google Privacy Policy.
On iOS, Posy will ask for your permission before allowing any cross-app tracking via Apple's App Tracking Transparency framework. You can change this permission at any time in Settings → Privacy & Security → Tracking.
We do not share your health or personal data with any third party. Google AdMob operates independently under its own privacy policy and only has access to the advertising-related data described above.
Your health data is fully under your control — you can export or delete it at any time from the app settings. To opt out of personalized ads, deny tracking in the ATT prompt or update your choice in iOS Settings.
If we make changes to this privacy policy, we will update the "Last updated" date above.
