PLO Privacy Policy
Last updated: October 27, 2026
The short version
- No sign-up needed. Google sign-in is optional.
- Your periods, symptoms and notes are stored on your phone.
- We never sell your data, and we never share reproductive-health data with advertisers.
- You can export or delete everything at any time in Settings.
What PLO stores on your phone
Period dates, flow, spotting, symptoms, symptom strength, private notes, the typical cycle and period lengths you choose to enter, and your app settings. This stays in PLO's private storage on your device. There is no PLO server that receives it.
Partner sharing (optional)
Only if you turn on partner sharing, PLO stores a small summary that you choose on Google Firebase (Cloud Firestore): the name you give your partner, whether you are on your period and which day, your approximate cycle phase, your estimated next period and fertile window, and, if you allow it, the names of today's symptoms. Private notes and your full history are never uploaded. PLO uses an anonymous Firebase ID for this, with no email or name. Only partners who enter your invite code can read your summary. Turning sharing off deletes the summary and all partner connections from the server.
Google sign-in (optional)
You can sign in with Google in Settings so your partner link carries over to a new phone. If you do, Firebase Authentication receives your Google account email address and name. Your cycle data is not uploaded because you signed in. You can sign out at any time.
Advertising
The free version shows Google AdMob banner ads on two screens. Ad requests contain none of your cycle, symptom or note data, are set to non-personalized, and PLO does not use the advertising ID. Like any ad, Google receives standard device and app information needed to show and count the ad. In regions where it's required, PLO asks for your consent through Google's consent form, and you can change your choice in Settings. You can remove ads with a one-time purchase.
Purchases
The one-time "Remove ads" purchase is handled by Google Play. PLO only checks with Google Play whether you own it; we never see your payment details.
Backups
If Google backup is turned on for your phone, Android may include PLO's data in your device backup, but only when that backup is end-to-end encrypted with your screen lock. You can also export a backup file yourself. Exported files contain your data, so store and share them carefully.
Reminders
Reminders are optional and are scheduled on your phone. Your lock screen only shows "You have a reminder".
Deleting your data
Settings › Delete all data erases everything PLO stores on your phone and removes any partner sharing from the server. Uninstalling PLO also removes the data on your phone.
Health information
PLO is for personal tracking only. Its estimates, including fertile window and ovulation, are calendar-based and are not medical advice, a diagnosis, or a method of birth control.
Children
PLO is not directed at children under 13.
Changes
If this policy changes, we will update this page and the date above.
