What you can do: - Search by name or phone number - Select several contacts and delete them with one confirmation - Restore deleted contacts from History within 30 days - Find duplicate contacts and merge them: the most complete contact is kept and the copies move to History, so you can undo a merge - Use light or dark mode Free and Premium: - Free: delete up to 5 contacts at a time, with ads - Premium (optional one-time purchase, no subscription): no ads, unlimited delete in one go, History with 30-day recycle bin and duplicate merge - If you bought Premium in an earlier version, it is still yours - You can restore a previous purchase from the app Privacy: your contacts never leave your device.

Where required, the app asks for your consent first, and you can decline personalised ads. iOS 18: if you give the app limited access to contacts, ContactsDelete works with the contacts you choose, and you can change the selection in Settings.
