Who Called?

Who Called is a private, offline-first contact organizer for the people, phone numbers, messages, and unknown callers you want to remember.

Keep a separate private contact list without adding records to Android Contacts. Search names, numbers, email addresses, social profiles, and notes while your records remain encrypted on your device.

Private Contacts

• Save names, companies, and multiple phone numbers
• Add email addresses, social links, birth dates, and notes
• Save up to three named anniversaries for each contact
• Mark favourite or hidden contacts
• Identify numbers that use WhatsApp
• Search by contact details or partial phone number
• Move contacts to Trash and restore them within 30 days

Optional Call History

On supported and policy-eligible Android builds, choose whether to display
recent phone call history after granting permission. Availability can vary by
distribution channel and Android permission eligibility.

• Review incoming, outgoing, missed, rejected, blocked, and voicemail entries
• See call time and duration where available
• Match calls with your private contacts and number tags
• Save an unknown caller as a private contact
• Tag an unknown number for future reference

Call history is displayed temporarily and is not saved in the app database or backup.

Quick Communication

• Open the phone dialer with a number ready for confirmation
• Start a WhatsApp or WhatsApp Business chat without first saving a contact
• Open the SMS composer with optional draft text
• Format international numbers using a selectable default country

Who Called never silently places a call or sends a message.

Saved Messages and Number Tags

Save important text you manually enter, paste, or share to the app. Organize
messages by title, sender, category, and favourites. The app can detect useful
OTP or reference codes within text you choose to save. Highlight or bold
selected text after saving, and use confirmed actions for detected phone
numbers and web links.

Attach temporary tags and notes to unknown phone numbers without creating complete contacts.

Keepsakes and Reminders

• Review birthdays and anniversaries for today, this week, this month, past month, next month, and upcoming dates
• Use a calendar view to track events with their contacts
• Optionally schedule one yearly Android reminder at approximately 6:00 AM
• Manage enabled reminders from the Alert Directory
• Disable one reminder or all reminders for a contact at any time

Notification permission is requested only when you enable a reminder. Web
builds do not display birthday or anniversary notifications.

Backup and Portability

• Create a complete encrypted .contactvault backup
• Protect backups with a separate passphrase
• Restore contacts, saved messages, number tags, and settings
• Import contacts from CSV or vCard files
• Export readable CSV or vCard contact files

Privacy and Security

Who Called encrypts application records locally with AES-256-GCM. It has no account, advertisements, analytics, trackers, or developer cloud.

Set an optional application PIN, use biometric unlock on supported Android devices, and enable screenshot protection where available.

Who Called does not read Android Contacts, your SMS inbox, notification content, or call audio. Your private organizer stays under your control.
