Signal vs Messenger
Side-by-side comparison of the Terms of Service and Privacy Policy of Signal and Messenger.
Signal offers unusually strong privacy commitments and minimal data practices compared with many messaging services, including explicit no-sale language and end-to-end encryption. Its downsides are mostly standard legal-risk protections for the company: liability limits, California forum selection, unilateral policy changes, account termination discretion, and required phone-number registration.
Signal’s legal terms are notably privacy-forward for a messaging service: it says it does not sell or monetize personal data, uses end-to-end encryption, and stores limited account and technical information. The tradeoffs are standard but important: required phone-number signup, international data transfers, broad service disclaimers, a $100 liability cap, California-only dispute venue, unilateral updates, and the ability to suspend or terminate access at any time.
Points of interest
-
positive ●●●●● termsNo data selling
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.
-
positive ●●●●● privacyEnd-to-end encrypted content
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.
-
negative ●●●●○ termsLiability capped at $100
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.
-
positive ●●●●○ privacyMinimal server-side data
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.
-
negative ●●●○○ termsPhone number required
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.
-
negative ●●●○○ termsCalifornia courts only
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.
-
negative ●●●○○ termsUnilateral changes and termination
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.
-
positive ●●●○○ termsYou keep ownership
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.
-
negative ●●○○○ privacyContact hashing uploads
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.
-
negative ●●○○○ termsInternational data transfers
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.
-
negative ●●○○○ termsNo emergency calling
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.
-
positive ●●○○○ privacyIn-app privacy controls
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.
Documents
Meta offers useful rights such as access, deletion, portability, change notices, and consumer court access in your home country. But those benefits are outweighed by extensive data collection, cross-product profiling, partner data flows, broad sharing, advertising use, and long deletion/backup retention timelines.
Messenger is governed by Meta’s broad platform terms and privacy policy. The legal posture is mixed: users get meaningful privacy rights, notice before major policy changes, and can generally sue as consumers in local courts, but Meta collects extensive cross-product and partner data, uses it for ad personalization, shares widely within Meta and with partners, and may retain deleted data for extended periods.
Points of interest
-
negative ●●●●● privacyExtensive data collection
Meta collects a very wide range of data, including activity, contacts, device identifiers, purchases, location, cookies, and partner data, even in some cases without an account. This enables deep profiling beyond simple messaging functionality.
-
negative ●●●●● termsAds use your data
If you use the free ad-supported version, Meta uses your information to personalize and measure ads on and off Meta products. This means your behavior and inferred interests help drive advertising decisions.
-
negative ●●●●○ privacyCross-product profiling
Meta may combine information across Meta products, and some cross-product use happens even without opting into Accounts Center. This can expand tracking and profiling across services.
-
negative ●●●●○ privacyBroad third-party sharing
Your information may be shared with other Meta companies, service providers, partners, law enforcement, and others for business, safety, and legal purposes. This broad sharing increases the number of entities handling your data.
-
negative ●●●●○ termsBroad content license
You keep ownership of your content, but grant Meta a worldwide, royalty-free, transferable, sublicensable license to use and modify it for service operation. This is broader than many users expect when sharing content.
-
positive ●●●●○ termsConsumer court access
Consumer disputes can generally be brought in the courts of your home country under local law. This is much more user-friendly than mandatory arbitration or foreign-exclusive court clauses for consumers.
-
positive ●●●●○ privacyPrivacy rights available
Meta says users have rights to access, correct, download, port, object to some processing, withdraw consent, and request deletion, subject to applicable law. These are meaningful privacy controls, especially for users covered by GDPR-style laws.
-
negative ●●●○○ privacyDeletion can take months
Deleting content or your account is not immediate: removal can take up to 90 days, plus up to another 90 days for backups, and some data may be kept longer. In practice, your information may remain in Meta systems for months.
-
negative ●●●○○ privacyPublic content spreads widely
Content you make public can be seen, reshared, downloaded, and indexed off Meta products, including by search engines and third parties. Once public, practical control over that content is limited.
-
positive ●●●○○ termsNo sale of identifiers
Meta states it does not sell personal information and does not share direct identifiers like name or email with advertisers without specific permission. That does not eliminate ad profiling, but it is still a meaningful limit.
-
negative ●●○○○ termsMeta can change terms
Meta can update the terms with 30 days' notice, and continued use counts as acceptance. Users who disagree generally must stop using the service.
-
positive ●●○○○ privacyAdvance policy notice
Meta promises notice before material privacy policy changes and at least 30 days' notice for most terms changes. This gives users some time to review changes and decide whether to continue.
