Privacy: your contacts never leave your device. ContactsDelete does not upload, store on a server or share your address book. The free version shows ads from Google AdMob. 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.
Language: the app follows your phone language and is available in 11 languages: English, Turkish, German, Spanish, Portuguese, Japanese, French, Arabic, Ukrainian, Russian and Hindi.
