Open the paywall and tap “Already bought — restore”, using the same store account you purchased with. If that does not work, check that you are signed into the right account (Apple ID or Google account) and restart the app. If it persists, send us the receipt and we will fix it manually.

No. The purchase is lifetime and tied to your store account: install Couplift on the new device, sign in with the same account and use “Already bought — restore”.

Note: your access is restored, but your content (diagnosis, diary, progress) is not — it never left the old device. Redoing the diagnosis takes a few minutes.

No. Apple and Google are independent stores and a purchase in one is not recognised by the other. If this happened inside the 7-day window, write to us before buying again.

Within the first 7 days, write to {{EMAIL_CONTATO}} with your receipt — the guarantee is full and has no fine print. In practice the refund is operated by the store:

• App Store: at reportaproblem.apple.com, with your Apple ID.
• Google Play: Play Store → Payments and subscriptions → Budget and history → the order → “Request a refund”.

If the store declines within our guarantee window, we sort it out with you directly.

No and no. It is a one-time payment with no renewal. There is nothing to cancel later — which is exactly why there is no “manage subscription” screen.

We cannot. There is no account and no server holding your content: everything is stored in your device’s own storage. The Privacy Policy spells out exactly what does leave the device (essentially: the purchase receipt).

Uninstalling the app erases all local data. To start over without uninstalling, useSettings → Delete my data. Step-by-step instructions are on the Data deletion page.

Only with unlocked access to your phone — the app has no passcode of its own in this version. Keep a screen lock on. If you do not feel safe writing on that device, do not write: read the section below.

It works. The program was designed so one person can start alone: most steps are about what you do, not about convincing anyone. There is no “couple account” and no partner invitation.

One step a day, sized to fit a normal day — usually between five and fifteen minutes. Cycles run about ten days and include rest days on purpose: consistency beats intensity.

Publicly available literature on relationships. Every factual claim the app makes is cited with work and year in the text itself — the central figure comes from the longitudinal follow-up of newlyweds published by John Gottman and Joan DeClaire in “The Relationship Cure” (2001).

Couplift follows your system language, with English and Portuguese available. You can pin the language in Settings, inside the app.

Check, in this order:

• that Couplift has notification permission in your system settings;
• that a reminder time is set in the app’s Settings;
• that Android battery optimisation is not suspending the app (on some manufacturers you have to mark Couplift as “unrestricted”);
• that a Focus mode (iOS) is not silencing the notification.

Close and reopen it — progress is saved at every step, so nothing is lost. If it keeps happening, send us what you were doing when it happened, your device model and the app version.
