WhatsApp vs Slack

For U.S. and Canada users, most disputes must be resolved through individual arbitration unless you mail an opt-out within 30 days. This sharply limits going to court or joining class actions.

Even if message content is not ordinarily stored, WhatsApp collects broad activity, device, connection, IP, cookies, and estimated location data. This can reveal patterns about who you interact with, when, and how often.

WhatsApp shares data with Meta companies not just for security and infrastructure, but also to improve products and ad experiences across Meta services. That expands use of your data beyond core messaging.

Messages sent to businesses may be accessible to the business and its service providers, which can include Meta. Those conversations may be stored, read, or otherwise processed under the business's own privacy practices.

WhatsApp says it does not normally keep your messages once delivered. Undelivered messages are kept encrypted for up to 30 days, which is comparatively privacy-protective for message content.

If WhatsApp harms you, its total liability is generally capped at $100 or what you paid in the last 12 months. For a free service, that usually means very little practical compensation.

WhatsApp says it may modify, suspend, or terminate access at any time, including for risk, harm, or long inactivity. That gives the company broad discretion to remove features or disable accounts.

You can request account information and port your data through an in-app feature. This gives users a practical way to inspect and move some of their information.

WhatsApp provides an in-app account deletion tool and explains that deletion removes account info, profile photo, group memberships, and message history from WhatsApp. It also warns that others may still keep copies.

WhatsApp can update its terms and treats continued use as acceptance after notice of material changes. If you disagree, your main remedy is to stop using the service and delete your account.

Outside specific limits for undelivered messages, WhatsApp keeps information as long as needed for service, legal, security, or enforcement reasons on a case-by-case basis. That leaves retention periods open-ended for many data types.

WhatsApp is not a substitute for phone emergency services and will not connect you to police, fire, or hospitals. Users should not rely on the app in emergencies.

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.
