No. Grouping, face detection, quality scoring and compression all run on your phone. Our servers hold none of your photos.

The one exception is when you order a printed product — the photos you chose for that order are uploaded to make it, and deleted within 90 days of dispatch.

No. Face detection only judges whether faces are sharp and eyes are open, so we can pick the better shot from a group of similar ones. We build no face templates, never match people across photos, and none of it leaves your device.

Pibook’s job is to look through your whole library — finding the similar, the duplicated, the blurry. With limited access it only sees the handful you picked by hand, which makes the organising and the statistics meaningless.

You can still grant limited access and the app will work; it just cannot help as much.

Yes, at any time — the switch is in Profile → Preferences. After that the app sends no analytics events at all.

Sign in to the store with the same Apple ID or Google account, then tap Restore Purchases on the Premium screen.

If you had signed in to a Pibook account, signing in again also brings your entitlement back automatically.

iPhone/iPad: Settings → your name → Subscriptions → Pibook → Cancel.

Android: Google Play → Profile → Payments & subscriptions → Subscriptions → Pibook → Cancel.

Premium continues until the period you already paid for ends. Deleting your account in the app does not cancel the subscription — it must be done in the places above.

In-app payments are collected by Apple or Google; we never receive them and cannot refund them. Apple: reportaproblem.apple.com. Android: request it from your Google Play order history.

If a defect in the app caused the problem, write to us first — we will help explain it to the store and compensate you where we can.

Check your connection, then tap Restore Purchases on the Premium screen. That resolves most cases.

If it still does not appear, email us your purchase date and platform and we will look it up and activate it manually.

Pibook holds no copy of your photos, so we cannot recover it directly. Your operating system usually still has it:

iPhone: Photos → Albums → Recently Deleted (kept 30 days).
Android: Google Photos → Library → Trash (kept 30 or 60 days).

We recommend confirming you have a reliable cloud backup before an organising session.

Progress lives on your phone. If you sign in and enable cloud backup you can restore it on a new device — we recognise the same photo by its fingerprint (a one-way hash of capture time and file characteristics), because system photo identifiers are completely different on a new phone.

If a photo lives in iCloud rather than on the device, the app has to ask the system to fetch it first, and that depends on your connection. The app also slows itself down when the phone gets warm, so it never gets in the way of what you are doing.

Profile → Account → Delete Account, or submit a request from this page, which explains exactly what is deleted, what is retained and how long it takes.
