Frequently asked questions

Quick answers about privacy, Pro, vault, team, tickets, and transfer.

What is ContactHub?
ContactHub is a local-first relationship hub for professionals: smart contacts, catch-up reminders, multi-contact tasks, business card studio, private vault, offline team workspace, and offline event tickets — on iOS and Android.
Is my data uploaded to your servers?
No. Contact lists and notes are stored on your device by default. We don’t run a ContactHub cloud that silently syncs your address book. When you share packages (transfer, backup, team, tickets), you choose where they go (AirDrop, Files, email, etc.).
Is the database encrypted with SQLCipher?
No. ContactHub uses sandbox SQLite protected by the OS. The private vault is a biometric / passcode UI gate. Passphrase backups use real AES-256-GCM encryption. See the Privacy Policy for details.
What’s free vs Pro?
Free includes limited contacts (50), catch-ups (5), tasks (3), vault contacts (3), and a small event trial (1 event · 10 tickets). Pro unlocks unlimited book, team, events, vault, encrypted backup, scanner event mode, AI note assist, and studio export. See Pricing.
How do I move contacts to a new phone?
Use Transfer contacts (.chbook): Share now or Save file on the old device, then Import on the new device inside ContactHub. This preserves tags, notes, timeline, vault flags, catch-ups, and tasks.
How does the private vault work?
Mark contacts as vault. They stay hidden until you unlock with Face ID, fingerprint, or device passcode. ContactHub does not open the vault without authentication. Set a device lock screen for best results.
Do offline event tickets need internet?
No. Tickets are HMAC-signed on device. Share QR codes, scan at the door offline, and use multi-host / check-in packages to collaborate without a backend.
How do team workspaces work?
Pro users create a team and share an invite QR. Teammates scan to join. Shared tags match contacts by phone. Publish updates via QR or file. Unlimited seats on Pro.
How do I restore a purchase?
Open ContactHub Pro in the app and tap Restore. Use the same Apple ID or Google Play account that bought the subscription or unlock.
Can I cancel Pro?
Yes. Cancel anytime in App Store or Google Play subscription settings. Access continues until the end of the paid period; restore then reflects the active state.
Which platforms are supported?
iOS and Android. Some features differ (for example, deep SMS inbox is limited by platform policy; messaging can open the system SMS app).
