Messaging
Messaging apps — WhatsApp, Telegram, Signal, Discord — promise privacy in marketing and varying levels of it in the legal text. Compare what's encrypted end-to-end versus what's just encrypted in transit, how metadata (who you talked to, when, for how long) is retained, and the law-enforcement request policies. Group chats, backups, and integrations with third-party bots often carry weaker guarantees than the headline DM experience.
