New ‘push-to-delete’ feature allowing users to securely delete sent messages from both a sender’s and recipient’s devices.

Encrypted messaging app SafeSwiss claims to have done away with email attachments being sent to the wrong person, with its new ‘push-to-delete’ feature allowing users to securely delete sent messages (along with pictures, documents and videos) from both a sender’s and recipient’s devices.

The new push-to-delete functionality has been rolled out in the latest update of the SafeSwiss secure messaging app for iOS and Android.

Along with deleting files across both devices, users can also opt to delete the message or file on their device, allowing the recipient to continue viewing the message. The new delete functionality is in addition to the existing timed delete feature.

The SafeSwiss platform’s robust security and privacy is based on ephemeral messaging using end-to-end (E2E) 256K elliptic curve cryptography encryption, meaning messages can only be decrypted by the sender’s or recipient’s devices in both one-to-one and group communications.

Other new features rolled out as part of the update include the ability to lock and unlock your account without PIN directly from home screen, as well as a new dropdown media management box, which shows a date-stamped list of all media files sent to a recipient.

The primary servers used by SafeSwiss are in Zurich, Switzerland, which has some of the world's strictest privacy protections. This means the service is beyond the legal reach of backdoor decryption demands of the Australian government.

To further protect users’ privacy, SafeSwiss does not require users to hand over personal details such as email addresses, phone numbers or even have a SIM card in order to set up an account.

SafeSwiss also supports secure peer-to-peer (P2P) voice calls and group voice conference calls, along with many other features including file transfers.
