On the same page, Telegram also lists one of its two tenets of internet privacy as “protecting your personal data from third parties, such as marketers, advertisers, etc.” That puts it in stark contrast to a myriad of services from Facebook, Google, Amazon, and others. Plus, if you’re using the “secret chats” feature, you’re getting the same level of end-to-end encryption. On top of this, users can’t forward or screenshot messages in secret chats, and messages can be programmed to self-destruct. Deleting a message also deletes it for everyone on the service, and users have the option to delete not just their own messages, but other users’ messages, too. It’s also worth mentioning that all chats are encrypted, even if not end-to-end encrypted.
