ContactSafe is a private address book of its own. It sits beside your phone's contacts rather than inside them, and everything you add stays on your device. WHAT YOU CAN ATTACH TO A CONTACT • Notes — write them, print them, or share them straight from the app • Files — photos, videos, audio, PDFs, scanned documents, anything • Folders — arrange a person's files, and give a folder its own cover image • Websites — save a link and reopen it any time • Locations — several named addresses per person (Home, Office, Summer house), each shown on a map • Projects — visits, calls and deadlines, with the people involved and the place pinned PROJECTS Give a project a start and an end, add the people involved, pin the addresses you collected from Maps, and keep its own notes and files with it. A reminder arrives an hour before it begins. Finished projects are archived rather than deleted. PRIVATE BY DEFAULT • No account, no cloud, no sync — there is nothing to sign up for • Nothing you add here appears in your phone's contacts app, and nothing is synced anywhere • No analytics and no third-party trackers • Works fully offline. Only the map previews and address lookup use the network LOCKED • Passcode and Face ID / Touch ID, with auto-lock after a delay you choose FIND ANYTHING • One search across contacts, files, notes and projects at once • Phone numbers are matched by their digits, so it finds the number however you type it • Projects can be found by their address or description, not only by name BRINGING YOUR DATA IN • Read people in from your phone's address book — nothing is written back • Move everything across from the previous ContactSafe app, on the device, files included YOURS TO KEEP • Back up everything — contacts, files, notes and projects — as a single file you keep yourself • Restore it on any iPhone • Export any contact as a vCard FIFTEEN LANGUAGES English, German, Spanish, French, Italian, Dutch, Polish, Czech, Greek, Russian, Ukrainian, Croatian, Serbian, Swedish and Mongolian.
