Synthesia can change these terms at any time by posting updates on its website, and if you keep using the service after changes take effect, you are considered to have agreed to the new terms.
This analysis describes what Synthesia'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
This clause establishes the mechanism and timeline by which the Service Provider may alter contractual obligations. The provision creates a system where acceptance occurs through inaction rather than affirmative consent, making the update process operationally efficient for the Service Provider while placing the burden of monitoring changes on users.
Interpretive note: The adequacy of website posting alone as legally effective notice for material contract changes may vary by jurisdiction and the nature of the change, particularly for EU and UK customers.
Continued use of Synthesia after a terms update constitutes acceptance of new terms, so customers should monitor for updates to the agreement and assess whether changes affect their compliance obligations or commercial relationship before continuing use.

"Synthesia may update or modify this Agreement at any time by providing notice to you, including by posting the updated Agreement on its website. Your continued use of the Services after the effective date of any changes constitutes your acceptance of the updated Agreement. If you do not agree to the updated Agreement, you must stop using the Services.— Excerpt from Synthesia's Synthesia Terms of Service
REGULATORY LANDSCAPE: The unilateral amendment clause interacts with contract law requirements in the UK and EU regarding notice and consent to material contract changes. Under EU consumer contract law and in some commercial contexts, unilateral amendment clauses must meet minimum notice standards. GDPR also requires that changes to data processing terms be communicated to controllers with adequate notice. The adequacy of 'posting on website' as notice may be disputed in certain jurisdictions. GOVERNANCE EXPOSURE: Medium. Enterprise customers with complex compliance dependencies on specific terms (data processing, liability caps, acceptable use restrictions) may face operational disruption if material terms change without adequate notice or opportunity to exit. The absence of a minimum notice period before changes take effect is a standard but significant gap in the terms. JURISDICTION FLAGS: EU commercial law may require more than website posting as effective notice for material contract changes, particularly where the change affects data processing or core service terms. UK contract law similarly requires consideration and adequate notice for enforceable unilateral variations. Enterprise customers should negotiate for email notification and a minimum notice period (typically 30 days) for material changes. CONTRACT AND VENDOR IMPLICATIONS: Procurement teams should negotiate for written (email) notification of material terms changes and a defined window to exit the agreement without penalty if changes are not acceptable. Legal teams should establish a monitoring process for terms updates, particularly regarding the Acceptable Use Policy and Data Processing Agreement. COMPLIANCE CONSIDERATIONS: Compliance teams should establish a process to receive and review Synthesia terms update notifications, and should assess whether any posted changes require updates to internal policies, consent mechanisms, or DPA documentation. A record of accepted terms versions should be maintained for audit purposes.
