How Telegram Protects Data (and Where Users Need to Be Vigilant):
Encryption: Telegram uses strong encryption. “Secret Chats” are end-to-end encrypted (E2EE), meaning only the sender and receiver can read messages. “Cloud Chats” (standard chats, groups, channels) are encrypted in transit and at rest on Telegram’s servers, with encryption keys distributed across different jurisdictions. This makes it difficult for Telegram itself or third parties to directly access your data.
Minimal Data Collection: Telegram collects minimal data necessary for service function.
No Data Selling for Ads: As stated, Telegram does not sell user data for advertising. Their ads are context-based, not user-profile based.
Privacy Controls: Users have robust privacy settings (e.g., controlling who sees their phone number, who can add them to groups).
