Privacy Policy

Millu — a relationship & connection app for couples. Last updated 20 June 2026.

Millu is built privacy-first. Your couple's data is visible only to you and your paired partner. This policy explains what we collect, why, and the control you have over it.

What we collect

• Account: your email address (for sign-in) and a display name you choose.
• Profile: optional avatar and birthday, and your app preferences.
• Your activity in the app: daily question answers, mood check-ins, love notes, connection-task responses, diary entries, optional period tracking, and your streak / league progress. This is content you create, shared only within your couple.
• Device push token: if you enable notifications, to deliver them.
• Subscription status: if you purchase Premium (handled by the app store + RevenueCat).

How we use it

• To provide the app's features and sync them between you and your partner.
• To send notifications you've opted into.
• To verify your subscription entitlement.

We do not sell your data, and we do not use it for advertising.

Who can see your data

• You and your paired partner — your shared couple data, enforced by database row-level security.
• Service providers we use to run the app: Supabase (database, authentication, storage), our push provider, and RevenueCat (subscriptions). They process data on our behalf, not for their own use.

Data retention & deletion

We keep your data while your account is active. You can permanently delete your account and all associated data at any time — in the app (Profile → Delete account) or by request. See how to delete your account.

Deletion is immediate and permanent; we do not retain a copy. Routine encrypted infrastructure backups, if any, age out within 30 days and are never restored to an active account.

Children

Millu is intended for adults and is not directed at children under 13.

Changes

If this policy changes materially, we'll update this page and the "last updated" date above.
