Effective 14 October 2026
This policy explains what data the Us Two mobile app (package app.ustwo.couples, “the App”) collects,
why, where it is stored and how to delete it.
The App is operated by the Us Two developer. Contact for any privacy question: ustwohelp@mail.ru.
| Data | Purpose | Who can see it |
|---|---|---|
| Email and password (the password is stored only as a hash by Google Firebase Authentication) | Sign-in, password reset | Only you |
| Name, gender, avatar colour, birthday (optional), “together since” date | Profile, Together counter, birthday and anniversary reminders | You and your partner |
| Chat messages: text, photos, stickers, reactions, drawings | Communication within the couple | You and your partner |
| Status updates (“Working”, “Relaxing”, …) | Showing your status to your partner and in widgets | You and your partner |
| Planner entries: tasks, events, notes, reminders, completion marks | Shared and private calendar | Shared entries: both of you; private entries: only you |
| Health data (only if you turn on cycle tracking): period dates, cycle settings, symptoms, mood, notes, intimacy and protection method, pill intake and pack settings | Cycle calendar, estimates, pill reminders | Only you. Your partner sees only a short summary limited to the items you explicitly enable under “What my partner sees” (all off by default) |
| Device push token | Delivering notifications about new messages, drawings and statuses | Nobody (technical data) |
The App does not collect location, contacts or advertising IDs, contains no ads, analytics or trackers, and does not sell or share data with third parties for marketing.
We process data based on the consent you give at sign-up and to provide the App’s features under the Terms of use. Health data is processed only after you enable cycle tracking yourself and only to provide those features. You can withdraw consent at any time by deleting your account (section 7).
Data is stored with Google Firebase (Google LLC): Firebase
Authentication, Cloud Firestore, Cloud Storage, Cloud Functions and Firebase Cloud Messaging, on servers in the United
States (nam5 / us-central1). Google acts as our data processor.
Data is encrypted in transit (TLS) and at rest by Google. The App is not end-to-end encrypted: the Firebase project administrator could technically access the data, but we do not look at it except when you ask us for help or when the law requires it.
Your partner gets access only after both of you link accounts with an invitation code. Server security rules prevent your partner from reading your private entries or detailed cycle data. You can unlink at any time: Profile → “Unlink partner”.
Data is kept while your account exists. When you delete your account, data is removed from our servers immediately; residual copies in Google’s systems are purged automatically within 30 days.
The App is intended for people aged 18 and over. We do not knowingly collect data from children.
Period and fertile-window predictions are estimates only. They are not medical advice and must not be used as contraception.
We may update this policy. The new version is published on this page; we will notify you in the App about significant changes.
