Postcard Keeper turns the shoebox under your bed into a beautiful, private collection that lives quietly in your iCloud. Snap the front and back of every postcard, tag it with the contact who sent or received it, and Postcard Keeper organizes everything for you. Postmarks become pins on a world map. Your address book grows with the people you exchange mail with. Statistics let you see how far your collection has traveled. KEY FEATURES • Built-in scanner — capture the front and back of each postcard with corner-by-corner cropping and automatic perspective correction. • Private by default — every postcard, contact, and note lives in your own iCloud account. We never see your data. • Searchable backs — Postcard Keeper reads the handwritten and printed text on the back of each postcard using on-device text recognition, so a search for "Lisbon" finds the postcard whose note mentions Lisbon. • A world map of your postmarks — every received postcard with a postmark becomes a pin you can explore. • Address book built in — track names, postal addresses, Reddit usernames, and Postcrossing usernames. Import directly from your phone's Contacts. • Tags and filters — organize by year, country, sent vs. received, or any tag you choose. • Shareable gallery — opt in to a public iCloud link that shares only the fronts of the postcards you choose. Back images, notes, and contact info always stay private. • Stats and history — see how many postcards you've collected, how many countries they've come from, and who you've exchanged the most with. • Export to PDF — generate a printable album of your entire collection in one tap. PLANS Postcard Keeper is free for up to 25 postcards. Two optional subscriptions unlock larger collections: • Plus — $0.99/month, up to 200 postcards • Unlimited — $1.99/month, no limit Subscriptions auto-renew monthly via your Apple ID and can be canceled anytime in iOS Settings.
