Photo Legacy: the fastest way to scan old photo albums and digitize them. Old family albums hold generations of memories. Scanning them print by print used to take a weekend. With Photo Legacy you open the album, point the camera at one page and tap once. On-device AI finds every photo on that page, crops each one and straightens it. A whole album takes one shot per page. KEY FEATURES - Whole-page detection: one shot per album page, every photo found automatically - Smart cropping: edges detected, album backing and plastic sleeve trimmed, skew corrected - Manual touch-up: drag corners, resize, or draw a missing box, all on the phone - One-tap enhance: four color styles (Original, Natural, Warm, Vivid) to revive faded prints - Save to your photo library in one tap - Share to LINE, WhatsApp or Messages, with an optional small "Scanned with Photo Legacy" line under the photo (off in Settings if you prefer) - ROC and Gregorian dates side by side, for families in Taiwan and Hong Kong PRIVACY FIRST, FULLY OFFLINE - Photos stay on your device by default; nothing is uploaded to any cloud automatically - Detection, cropping and enhancement all run on the device, no network needed - No sign-up, no account, no ads SUPPORTER EDITION (one-time purchase, not a subscription) Scanning, organizing, editing, saving and sharing are free. If you want to support an independent developer, a single purchase unlocks: - Album backup file: export a whole album as one file and import it on your next phone (importing is always free) - Album Book PDF: lay an album out as a printable, shareable photo book with captions and dates - Full-resolution export: save a whole album to your photo library at original quality, with date and caption written into each photo Purchases are kept by the App Store and can be restored on devices signed in with the same Apple Account. BUILT FOR - Adult children digitizing their parents' albums - Family historians and genealogy researchers - Older relatives who want to pass prints on to family far away - Anyone who wants family photos scanned without handing them to a cloud YOUR PHOTOS STAY YOURS Nothing is sent to a server by default. The optional "Help improve AI" setting is opt-in and uploads album-page images only, to improve photo detection; pages are kept for up to 12 months, a few for up to 3 years. Turn it off any time, or write to us to have your data deleted. Grandparents' albums, childhood years, weddings and reunions: scan them one page at a time and pass them on.
