Signal can change these terms at any time, and simply continuing to use the app counts as your agreement to the new terms.
This analysis describes what Signal's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability and practical outcomes may vary by jurisdiction, enforcement context, and individual circumstances. Read our methodology
Signal is not required to notify you directly when terms change; updating the 'Last Modified' date is the only specified notice mechanism, meaning material changes could take effect without you being explicitly informed.
Interpretive note: GDPR and EU consumer protection law may require more affirmative notice mechanisms than a 'Last Modified' date update; enforceability of deemed-acceptance by continued use varies by jurisdiction.
Signal can modify its terms without direct notice to users; continued use of the app following any update constitutes acceptance of the new terms, which means users who do not regularly check the terms page may unknowingly agree to changed conditions.
