With Contacts Backup, you can easily back up the Address Book on your device without the need for any servers or synchronization.
With Contacts Backup, you can back up all contacts in your address book with a single tap and send this backup file with the .vcf extension of vCard format to yourself as a mail message. Later, if your address book is completely or partially deleted, you can restore your contacts by opening the backup file you have sent yourself with the Mail application on the Phone.
You do not need to apply to return your guide. All you need is a Mail application and a backup file with a VCF extension that is stored in your mail account.
Our application does not send your directory to any server, so it is 100% safe.
