No. Every bit of analysis — finding duplicates, detecting blur, recognizing screenshots and documents — runs on your iPhone using Apple's on-device Vision framework. Lumavault has no servers and no accounts. Your photos never leave your device.

Yes. Open the Photos app, go to Albums → Recently Deleted, find the photo, and choose Recover. iOS keeps deleted photos there for 30 days before removing them permanently.

That's usually Recently Deleted still holding the files — they don't free up space until they leave that album. You can empty it manually in Photos → Albums → Recently Deleted → Select → Delete All. If you use iCloud Photos, it can also take a while for the change to propagate and for your device to reclaim the space.

To find duplicates and near-identical shots, it has to compare photos against each other across your whole library. Limited access would let it scan only the handful of photos you picked, which defeats the point. The access is used solely for on-device analysis — see our privacy policy. You can change or revoke it any time in Settings → Privacy & Security → Photos.

Lumavault scans incrementally — it starts with your most recent ~500 photos so you can begin cleaning right away, then keeps working through the rest of the library. On a very large library the full pass can take several minutes, because your phone is analyzing every image locally rather than offloading the work to a server. Keeping Lumavault in the foreground and your iPhone plugged in speeds it up considerably.

Blur detection and “best of a burst” suggestions are judgment calls, so Lumavault only ever suggests — you decide. Just swipe to keep it. For blurry photos you can also adjust the sensitivity threshold in the app if it's flagging more than you'd like.

Compression saves a smaller copy of a large video first, and then you decide what happens to the original. It's a trade-off: you get the storage back, at some cost to quality. If a video is irreplaceable, keep the original rather than compressing.

Open Lumavault, go to Settings inside the app, and tap Restore Purchases. Pro is tied to your Apple Account and works on every device signed in to it. Make sure both devices use the same Apple Account.

No. Pro is a single one-time purchase with no renewal and nothing to cancel.
