About

LockContacts

Features
Read full description

LockContacts is a private contact manager with its own app-only address book, separate from iOS Contacts. Contacts saved in LockContacts are not written to your iPhone address book, so apps that read iOS Contacts cannot see them. Use it for people you want to keep organized without mixing them into your system contacts. What you can do: - Add contacts manually, copy selected entries from iOS Contacts, or import CSV, XLSX, DOCX, PDF, and VCF files - Match file columns so names, phone numbers, emails, companies, and groups go into the right fields - Scan business cards with the camera and save names, phone numbers, and emails - Put one person in multiple groups with nested tags such as #Work/Dev - Pin important people and find anyone quickly - Keep notes and meeting notes with attendees, date, location, and formatted text - Add meetings to iPhone Calendar or export them as .ics files - Get birthday reminders, call, text, email, and open addresses in a map app - Merge duplicate contacts - Lock the app with Face ID or Touch ID after 30 seconds in the background - Turn on iCloud Sync when you want your contacts and meetings in your own iCloud account - Export your data as vCard or CSV LockContacts supports 9 languages: English, Korean, Japanese, Simplified Chinese, Traditional Chinese, German, Spanish, Italian, and Turkish. Free and LockContacts Pro: Use every feature for free with up to 5 contacts and ads. LockContacts Pro is a monthly or annual subscription for unlimited contacts and no ads. The annual plan includes a 2-week free trial. You can cancel your subscription at any time. No sign-up is required. Your data stays on your device, and in your own iCloud account only if you turn on iCloud Sync.
