Chat with your friends securely and secretly by self-encrypted communication.
Easy to use messenger tool that use encryption/decryption techniques to only send coded messages free via the web.
You chose the encryption key, stored double-encrypted on your device, using a Password potentially stored nowhere and that only you know.
Send the messages encoded, and decoded by a PasCode only you and your friend, the recipient, knows.
We don't have these PasCode's so we can't see any details of your messages or who they are for, and we don't want to because we are not planning to scan your data so we can give you better ads.
We recommend that PasCodes used for messages between friends/groups are communicated only verbally face to face, are ones only you know and are not sent by any electronic means of communication.
How to send a message:
- You and your friend downloads ChatS from Google Play
- You set it up by filling in a Display Name (used by your friends as Contact Name) and Password (used to encode what is stored on your device) and press Register Now
- You select Contacts, then Create Contact and enter your friends Display Name as the contact Display Name and a mutually agreed PasCode. Your friend does the same entering your Display Name and the same mutually agreed PasCode in his/her contacts.
- You select Sent Messages and Create Message, write your message subject and text as you would a normal email/sms, select your friend as the recipient (by long clicking/pressing on his/her name in the Out list to move it to the In list). Press Encrypt and then Send. ChatS will encrypt the message and send it to the MoonC.mobi server.
- Your friend selects his/hers Received Messages, presses Refresh and his/her ChatS will check MoonC.mobi for new messages, download the message from you, decrypt it and when selected display the original text.
There is Contact Group option for multi way conversations
The decrypted message will only be visible on yours and your friends device and the PasCode to decrypt it will never leave your devices.
ChatS use a new encryption technique specifically developed for this app and do not depend on standards neither regarding formulas nor keys.
If you don't like ad's there is a paid no ad version called ChatSy available.
ChatS is adjustable to the following languages by pressing the button marked EN:
English, Norwegian, Danish, Swedish, German, French, Italian, Spanish, Portuguese, Dutch, Chinese, Polish, Russian, Japanese, Hindu and Arabic.
