Telegram vs Signal

Telegram says it does not use personal data for ad targeting. Sponsored messages in public channels are contextual rather than based on user profiling.

Secret chats are end-to-end encrypted and Telegram says it cannot read them. It also says it does not store secret chats as readable server-side content.

Normal cloud chats, media, and files are stored on Telegram’s servers so they sync across devices. That is convenient, but it means standard chats do not get the same privacy model as secret chats.

Using bots, mini apps, business chatbots, translation, voice-to-text, and payments can send data to independent third parties. In some cases bots may access messages in chats assigned to them.

Telegram Premium renews automatically until canceled, and deleting your account or app does not stop billing. Early cancellation generally does not give a partial refund or credit.

Users can delete their account and cloud data, and Telegram recognizes access, correction, deletion, objection, restriction, and portability rights under applicable law.

Telegram may collect IP address, device/app usage, and username-history metadata for security and abuse prevention, and can keep it for up to 12 months.

Your chosen screen name, username, and profile photos are always public. That makes discovery easier, but reduces default privacy around account identity.

Telegram reserves the right to update its terms and privacy policy later. Privacy-policy changes take effect when posted, though Telegram says important changes will be notified in-app.

Telegram can temporarily or permanently ban accounts for violations, and says it will not compensate users for lost Premium benefits. Reported cloud-chat messages may also be reviewed by moderators.

Telegram says its web service uses only operational cookies and not cookies for profiling or advertising. This is a meaningful privacy-positive compared with many web services.

Telegram says it may disclose IP address and phone number only under valid criminal-authority orders and will include such disclosures in a quarterly transparency report.

Signal explicitly says it does not sell, rent, or monetize your personal data or content. That is a strong privacy commitment compared with many ad-supported services.

Signal says it cannot access the contents of your messages or calls because they are end-to-end encrypted. In practice, this sharply limits what the company can read or disclose about your communications.

If Signal harms you, its total contractual liability is capped at $100 to the extent allowed by law, and many categories of damages are excluded. This significantly limits practical remedies.

The policy says message history stays on your devices and that server-side technical data is limited to what is necessary to operate the service. This reduces the amount of personal information retained centrally.

You must sign up with a phone number and accept verification texts or calls. That creates an identity link many privacy-conscious users may prefer to avoid.

Disputes must be brought in specified California courts under California law. This can make it harder or costlier for non-California or international users to pursue claims.

Signal can update its terms and privacy policy, with continued use treated as acceptance, and it may suspend or terminate access at any time for any reason. Users have limited leverage if terms worsen or access is cut off.

Signal states that you own the information you submit through the service. Notably, the terms do not describe a broad content license letting Signal exploit user content.

If you use contact discovery, Signal may hash address-book data and send it to its servers to find other users. This is optional and privacy-protective by design, but still involves sharing derived contact data.

Signal says encrypted information and metadata may be transferred to the United States and other countries where it or its providers operate. Users outside those countries may face different legal protections.

Signal is not a substitute for emergency services. Relying on it in a crisis could be dangerous because it does not connect to police, fire, hospitals, or similar services.

Users can manage personal information and enable extra protections like a Registration Lock PIN in the app settings. This is a useful transparency and account-security feature.
