Sem's is a secure SMS-style messenger app providing you with privacy when communicating at last. No matter whether you’re just chatting with your friends or whether you are a doctor, lawyer, tax adviser, journalist, someone whose profession is built on trust and privacy, you can communicate to your partners with no fear of being tapped, now. The use of Sem's is FREE of charge.
How it works
Sem’s encrypts your messages (and documents, the Pro Edition) in a way that it can only be decrypted on the recipient’s device. We cannot read your messages, nor can anyone else.
With Sem’s you are identified by your phone number, very much like text messaging (SMS). You have to provide us with your phone number (see “Privacy”) when running Sem’s for the first time. Our server sends a text message (SMS) to your phone in order to verify your phone number. This message is captured by Sem’s. You can use Sem’s only if you provide us with your correct international phone number. Sem’s requires an internet connection to operate. Assuming you’re on a flat mobile internet contract or using WiFi, no costs occur when using Sem’s. Hence, it’s an inexpensive alternative to text messaging, too.
For registration, internet access as well as phone service (for reception of one SMS) are required. For sending and receiving messages, merely internet access is required.
All editions, including the free Community Edition, are FREE from advertising, as we think that ads massively spoil the user experience. If you like our service and want it to be continued, we kindly ask you to upgrade to the Pro Edition.
Privacy & App Permissions
Privacy is what Sem’s is all about, so we care a lot about yours. Sem’s NEVER transfers any private data, such as address book data, account information, passwords, images, files, videos, etc. from your device to our servers nor aggregate any information in the device. The content of a Sem’s message itself cannot be decrypted by us, but ONLY by the recipient. Let us explain why the app requires certain permissions:
Well, Sem’s uses the internet to send and receive messages.
