Telegram vs Microsoft Teams

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.

U.S. residents must use informal resolution and then binding individual arbitration, with a class action waiver. That limits the ability to sue in court or join a class action, though small claims remains available.

You keep ownership, but grant Microsoft worldwide, royalty-free rights to copy, retain, transmit, reformat, display, and distribute your content as needed for the service and improvement. If you share content broadly, others may also reuse it widely without compensation.

Microsoft says it collects account data, device and usage data, location, contacts, content, communications, and data from affiliates, partners, brokers, and public sources. That is a broad data footprint for a messaging service.

If Teams is provided by an employer or school, that organization can manage settings and access account data, diagnostics, files, and communications. Users on work or school accounts should assume their organization may have significant visibility and control.

Microsoft says you can access exportable data through the privacy dashboard or product interface, and that this data can help you switch providers. That is a meaningful portability feature if you want to leave Teams or back up your information.

If you close your account or cancel the service, Microsoft says it will delete or disassociate associated data and content, subject to legal retention obligations. That gives users a clear exit path, though they should back up anything they want to keep.

Subscription payments continue until you cancel, and Microsoft says you must cancel before the next billing date to avoid being charged again. This creates a real risk of ongoing charges if you miss the cancellation deadline.

Microsoft can change the terms at any time, and continued use after the effective date counts as acceptance. That means users need to monitor updates or risk being bound by new rules automatically.

The privacy policy says you can request access, deletion, correction, restriction, objection, portability, and consent withdrawal. These are strong baseline privacy rights, even if some access is limited by law or product design.

Microsoft says it does not use email, human chat, calls, voicemail, documents, photos, or other personal files to target ads. For a messaging product, that is an important limitation on ad profiling of message content.
