Perplexity can change these terms at any time, and if you keep using the service after being notified, the company treats that as your agreement to the new terms.

This clause means that material changes to user rights, data use, or other terms can take effect quickly, and continued use is treated as acceptance without requiring an explicit affirmative consent step.
The agreement authorizes Perplexity to amend terms unilaterally, with notice delivered by email, in-service notification, or date update, and treats continued service use as binding acceptance of amended terms. Users who do not monitor for term change notifications may be bound by materially revised terms without realizing the terms have changed.

"We reserve the right to modify these Terms at any time. If we make changes, we will provide notice of such changes, such as by sending an email notification, providing notice through the Services or updating the 'Last Updated' date at the top of these Terms. Unless we say otherwise in our notice, the amended Terms will be effective immediately, and your continued use of our Services after we provide such notice will confirm your acceptance of the changes.— Excerpt from Perplexity AI's Perplexity Terms of Service
(1) REGULATORY LANDSCAPE: In the EU, unilateral modification clauses in consumer contracts may be subject to the Unfair Contract Terms Directive, which requires modification rights to be clearly justified and may require active consent for material changes rather than acceptance by continued use. UK consumer protection law imposes similar constraints. The FTC has authority over deceptive practices, including cases where consumers are not meaningfully informed of material changes to data use or dispute resolution terms. (2) GOVERNANCE EXPOSURE: Medium. The primary risk is that material changes to data use, arbitration scope, or liability terms take effect without users having meaningfully reviewed and consented to those changes. For enterprise agreements, this creates contract management risk if key terms are altered during the contract lifecycle. (3) JURISDICTION FLAGS: EU/EEA and UK jurisdictions impose heightened requirements on modification clauses in consumer contracts, potentially requiring affirmative consent for changes that affect consumer rights. California's consumer protection framework may also impose constraints on the scope of implied consent through continued use. (4) CONTRACT AND VENDOR IMPLICATIONS: Enterprise customers should include a contractual right to notice and review periods for material term changes in any negotiated agreement with Perplexity. Procurement teams should establish a monitoring process to track published changes to Perplexity's Terms of Service. Standard-form click-through acceptance of modification via continued use may not satisfy procurement policy requirements for enterprise software. (5) COMPLIANCE CONSIDERATIONS: Legal teams should set up monitoring alerts for changes to Perplexity's Terms of Service, particularly for provisions affecting data use, arbitration, and liability. Where material changes occur, a fresh assessment of whether the updated terms are compatible with organizational policies and applicable regulatory obligations should be conducted.
