Ever Wondered Why STIX...

Doesn't Support Phone Calls?

STIX prioritizes secure and reliable communication, which is why phone calls are not supported. Calls over the Tor network—integral to STIX's privacy and anonymity — are technically challenging and impractical due to several inherent limitations. We are actively working on a solution and we will provide it until Q3 2025.

Isn't Available on iOS?

The iOS platform poses significant challenges for Tor-based messaging apps like STIX due to restrictions in Apple’s ecosystem and technical requirements specific to the Tor network.
