Seca Contacts

Seca Contacts is the address book of the Seca suite: Contacts, Phone and Messages, three apps sharing one Material 3 Expressive design, built for privacy. They run on any phone with Android 12 or newer, with or without Google, and are at their best on GrapheneOS. In English and French. Your contacts stay on your phone

• No Internet permission: the app cannot send anything anywhere.
• Contacts stay in Android's own address book, where DAVx⁵ or any sync of your choice can reach them.
• Works with GrapheneOS Contact Scopes.

• Coloured profiles (Family, Work…), whose colour carries over to Seca Phone and Seca Messages.
• Favourites, instant search, fast scrolling by letter.
• Duplicates found by name or number, merged without losing anything.
• Your own card, shared as a QR code.

• vCard import and export.
• Password-encrypted backup.
• App lock, and a hidden preview in recent apps.
• Wallpaper colours or Seca palettes, dark theme.

Sixth beta, for F-Droid again: the build patches itself where their scanner needs it, installs Rust the way their servers expect, and pins the same NDK as theirs so their APK and this one come out identical. Nothing changes on the phone.
