Private Contacts: Offline Book

Your address book is one of the most sensitive things on your phone. Private Contacts keeps it that way: an offline contacts book that asks for NO permissions, NEVER touches the network, and stores everything in the app's own private folder. No account, no sign-up, no cloud, no tracking.

🛡️ ZERO PERMISSIONS — REALLY ZERO
Open your system settings and check: this app declares no permissions at all. Not contacts, not storage, not camera, not internet. Nothing to grant, nothing to leak. Every feature that would normally need a permission is instead handed to the system apps you already trust.

📵 NO NETWORK, EVER
The app has no way to reach the internet. Your data cannot be uploaded, synced or "backed up to us" — because there is no us. Everything lives on your device, in a private directory other apps can't read.

🔄 BACKUP YOU CONTROL
The one exception is Android's own Auto Backup: if you leave it enabled, the system may copy the app's files to your personal Google account — handled entirely by Android, never by us. When encryption is on, only the encrypted blob is ever backed up, and you can turn Auto Backup off in your device settings. You can also export a manual copy anytime.

🔐 OPTIONAL PIN ENCRYPTION
Turn on encryption with a single switch and protect the whole book with a PIN:
• AES-256-GCM encryption with an Argon2id key derived from your PIN
• Built to resist forensic extraction — chip-off, custom recovery, adb backup, cloud backup
• Without the PIN, even a full image of your storage is unreadable
• No secret backdoor, no cloud reset: your PIN is the only key. If you lose it, the data is gone — and that's the point.

🕵️ MADE FOR PRIVACY-CONSCIOUS PEOPLE
• No ads, no analytics, no trackers, no telemetry
• No advertising ID, no fingerprinting
• Optional screen-capture protection blocks screen recording and the recent-apps preview of your data
• Everything works fully offline, in airplane mode, forever

👤 A REAL CONTACTS APP
• Names, organization, multiple phones, emails and addresses
• Birthdays, website, free-form notes
• Custom labels — plain text OR emoji — on any phone, email or address
• Avatars: pick a photo, choose an emoji, or fall back to a clean monogram
• Photos are added through the system photo picker or camera — again, without granting the app anything

📞 ONE-TAP ACTIONS (WITHOUT PERMISSIONS)
Call, text, email, open a website or drop an address on the map — each action hands off to the right system app, so the permission stays with that app, never with us. Long-press any field to copy it.

🔎 FAST SEARCH & SORT
• Search across every field at once — name, organization, phones, emails, addresses, website, notes, even birthdays
• Sort by first name, last name, full birthday, or the next upcoming birthday

📤 EXPORT & IMPORT — YOUR DATA IS YOURS
Full control over your own data, in open formats:
• JSON, or JSON + photos in a ZIP — lossless backup and device-to-device transfer
• vCard 3.0 and 4.0 archives — compatible with Google Contacts, iOS and Outlook
• CSV table for spreadsheets
• Self-contained HTML with live search and a cards/table view — opens offline in any browser
Import back from JSON, ZIP or vCard, with replace / add / merge options. No lock-in, ever.

🎨 CLEAN & MODERN
• Light and dark themes, or follow the system
• Optional phone-number formatting for display only — stored numbers stay exactly as you typed them
• Add a contact to your system contacts, or pull one in, entirely through system dialogs

🚫 WHAT WE DELIBERATELY LEFT OUT
No cloud sync, no social features, no call history, no widgets, no analytics. Less surface, less risk, more privacy.

Private Contacts is for anyone who believes their address book should belong to them and no one else. Install it and keep your contacts truly private.
