Microsoft Teams vs Slack

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.

Slack collects account details, logs, device information, approximate location, cookies, imported contacts, third-party integration data, and audio/video metadata. That gives Slack a fairly detailed picture of how you and your device use the service.

Owners and administrators may be able to access, modify, or restrict access to information, including profile details and workspace activity logs. In a workplace account, your employer may therefore have substantial visibility into your use of Slack.

If a workspace enables third-party services, Slack may receive and share information with those providers, and those services run under their own policies. Users should assume integrated apps can expand where their data goes.

Slack keeps non-customer personal data as long as necessary for support, legal compliance, disputes, and business purposes, including after account deactivation. That means some data can persist well after you stop using the service.

Slack transfers personal data outside your country, including to the United States and other countries. While it cites safeguards like Standard Contractual Clauses, cross-border transfers still increase jurisdictional exposure.

Slack says users may request access, correction, and deletion of personal information, and can use account settings tools where available. For workspace-controlled data, though, you may need to contact the customer/administrator.

California users get CCPA/CPRA rights, including deletion, disclosure, and opting out of certain ad-related sharing. Slack also recognizes Global Privacy Control for cookie-based sharing signals.

Slack uses personal data to send marketing emails and other promotional communications. You can control some of these messages, but marketing is still an express use of the service data.

If you use Slack through an employer or other customer, that organization controls workspace settings and Customer Data. Practically, this means your message and file access rights may depend more on your workspace admin than on Slack itself.

The terms expressly say the Slack Terms are a binding agreement. This is standard, but it means use of the service is legally governed by incorporated agreements you should read carefully.
