SIMSme is the secure messenger of Deutsche Post. SIMSme protects your data from access by hackers and third parties. The messenger offers state-of-the-art features and is free and ad-free at the same time. We use a true end-to-end encryption with servers only in Germany. The service is GDPR compliant and protects your privacy.

Messages are encrypted on the sender's device and can only be decrypted on the recipient's device. The private keys never leave your smartphone. Not even we can read your messages!

We at Deutsche Post do not collect your data, do not evaluate it or sell it. We will not show you any advertisements in the future. SIMSme for private customers is and remains free. The service is financed by the company's enhanced SIMSme Business version.

The SIMSme servers are only located in Germany. Of course, this also means that your data will be treated according to German privacy policy! In addition, the service is GDPR-compliant.

SIMSme protects your privacy and offers everything you expect from a messenger - and more:

- Send text and voice messages
- Share videos, pictures and locations
- Send files of any format (pdf, mp3, doc, zip etc.)
- Confidential information can be sent as self-destructive messages
- To remind someone, you can send delayed messages
- Create groups of up to 100 participants
- Chats can be muted individually
- Verify the identity of contacts by scanning the QR code
- With the SIMSme-ID, you can communicate anonymously
- You can see when the chat partner is online (optional)
- Messages can be sent with push preview (optional)

With SIMSme you can have your sent messages automatically destroyed so that the recipient can only view them for a limited time.

Contacts can be verified by scanning a QR code. This verification shows which contacts you've actually made and protects the user from possible man-in-the-middle attacks.

Pure crap...uninstalled

Difficult to send voice messages. Who the hell thought to put the icon of send close to delete?

Works great

Took a while to understand the little nuances but afterwards, works perfectly as advertised. You have to invite contacts to join the secure network, but the benefits of undecipherable, encrypted communication far outweigh the effort. Like most German products: TOP GRADE !

Insecure behavior

I downloaded and installed this app. Wish I had not. I had not yet initiated any conversations, nor even launched the app when two weeks later I received a “Secure message” alert in iOS8.3 from within the app SIMSme …. What?? Who could possibly know I even have the app on my device? The answer: Only Apple and apparently the developer. I have removed this app and recommend you do not trust it either.
