How we protect your privacy
Private by design, not by promise
End-to-end encryption
Messages, photos, calls and video calls are encrypted on your phone with MLS, an open standard (RFC 9420).
We do not keep your conversations
The server only holds encrypted data until it is delivered, with an expiry date. It can never read it.
No ads, no trackers
We do not sell data, there is no advertising and this site uses no third-party analytics.
Made for families
In Kids the guardian approves every contact. Nobody can write to a child without their permission.

Frequently asked questions
What people ask us most
Are the apps free?
The apps are a free download. SO Chat Free gives you one-to-one text messages and voice calls, end-to-end encrypted. Photos, videos, documents, voice notes, video calls and groups come with Plus or a higher plan, activated with a code.
How do I pay?
By bank transfer. You choose the plan, leave your e-mail, see the transfer details with an order number and upload the receipt (photo or PDF).
When does my code arrive?
We confirm each payment by hand during business hours and the code is e-mailed to you right then. An order that is not paid within 5 days expires on its own.
Can you read my messages?
No. They are encrypted on your device and only the recipient can decrypt them. Neither we nor a company's administrator can read them.
Do I need to give my phone number?
No. Your account is created with a name and an @alias. We do not ask for your e-mail to use the app either: only to send you a code if you buy.
How does the yearly plan work?
It lasts 12 months and costs 10. It starts when you redeem the code, and you have 90 days to redeem it.
What happens when my plan ends?
Your account goes back to Free (text messages and voice calls). Nothing is deleted from your devices.
Is there an iPhone app?
Not yet available for download: the iPhone app is being tested and will come first through Apple's TestFlight and then to the App Store.
And on the computer?
The Windows, Mac and Linux app is a free download and is activated with a Familia or Kids plan (to supervise your children) or a Business plan (administration and meetings).
