I had never heard of the third app they suggest as a replacement (Teleguard), which is apparently also a Swiss product. Looking at their Privacy Policy[1], they make a suspiciously claim to not log anything. Not even payment information (whatever that means). Which makes me wonder how they combat fraud, spam and fake accounts. And, ultimately, the product being closed-source I guess you will just have to trust their claims.. just like WhatsApp and Telegram that Swisscom advises against for that same reason.[2] [1] https://teleguard.com/en/privacy https://teleguard.com/en/privacy [2] Actually, some parts of Telegram’s code is open source. Although it’s only the clients so the point about trust stands.
