“ Your input and output, such as questions, prompts and other content that you input, upload or submit to the Services, and the output that you create, and any collections or pages that you generate using the Services (“ Service Interaction Information ”). Service Interaction Info…”
“ Except as expressly provided in this Agreement, including our Trademark and Brand Usage Policy, or otherwise permitted by law, no Prezi Content may be used, copied, reproduced, communicated to the public, modified, republished, uploaded, posted, publicly displayed, publicly perf…”

“ While you may be able to create Private User Content during the Trial Period, Prezi reserves the right to designate such Private User Content as Public User Content after the conclusion of the Trial Period if you do not convert your free trial into a paid Prezi account.”
“In addition to the specific uses described above, we may use most of the above information to provide you with and improve the Services (including our AI models) and to maintain our business relationship, including by enhancing the safety and security of our Services (e.g., troub…”
User data — which includes 'most' categories described above (including Service Interaction Information, i.e., prompts and outputs) — may be used to improve AI models. No opt-out mechanism is described here.
“Re-useable Public User Content. If your content is designated as Public User Content, you may choose to “allow re-use” of that content (in the case of videos that are designated Public User Content, you are required to allow re-use). We may share your reusable Public User Content…”
Public User Content (and for videos, mandatorily so) may be shared with third-party AI partners for training and commercial AI R&D. Users on free/public accounts have very limited ability to opt out of this use.
“ If we become aware that we have unknowingly collected information about a child under 13 years of age or the relevant minimum age in your jurisdiction, we will make commercially reasonable efforts to delete such information. If you are the parent or guardian of a child under the…”
“ Without Prezi’s express written permission, sell access to the Services or sell advertising, sponsorships or promotions placed on or within the Services or any User Content.”
“To the extent the laws in your jurisdiction do not recognize the legal basis of legitimate interest or another legal basis specified above for a particular purpose, you consent to the processing of your personal information for that purpose through using the Services.”
Perplexity uses mere use of the Services as implied consent for processing where 'legitimate interests' is not recognized as a valid legal basis. This is a broad fallback consent mechanism that may not be valid under GDPR or other strict privacy regimes.
“ This license ends one year after you delete your Private User Content or your account is closed (either by you or by us), except (i) to the extent that your Private User Content has been shared with others and they have not deleted it, (ii) that if you are a habitual resident of…”
“This Privacy Policy does not cover the use of the Perplexity API or Enterprise Pro, where we act solely as a processor, and which are governed by the applicable Terms and Conditions, including the Data Processing Addendum incorporated therein, that you agree to when signing up fo…”
API and Enterprise Pro users have different (and potentially stronger) data-processor protections under a DPA, whereas free/Pro/Max users are governed by this policy which permits broader use of their data.
“Prezi Public (free) Accounts. If you have a Prezi Public (free) account, all of the User Content you create, including all of the information within your presentations, your videos, your other content, and your username will be available to anyone who has access to the internet (…”
Free account users have all content made public by default with no general right to privacy; only users with 'specific licenses' may create private content. This represents a significant tier-based risk difference.
