“We claim no ownership rights in your User Content. You hereby grant to us a perpetual, irrevocable, nonexclusive, royalty-free, sublicensable, fully paid, worldwide license to create derivative works from, access, reproduce, distribute, process, publish, display, perform, adapt,…”
Despite claiming no ownership, Descript takes an extremely broad, perpetual, irrevocable, sublicensable license over all user content including name and likeness, across all current and future media channels, with no compensation.
“ 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…”
“We claim no ownership rights in your User Content. You hereby grant to us a perpetual, irrevocable, nonexclusive, royalty-free, sublicensable, fully paid, worldwide license to create derivative works from, access, reproduce, distribute, process, publish, display, perform, adapt,…”
Descript disclaims ownership of user content but takes back a sweeping perpetual, irrevocable license to outputs/edited content. The scope of 'improve the Descript Service' is broad and could encompass model training.
“ Information we receive when you choose to link any third-party platforms to your account, such as when you sign into your account through Google or Apple (“ Third Party Platform Information ”) or when you voluntarily link one or more of your health and wellness applications (suc…”
“You hereby grant to us a perpetual, irrevocable, nonexclusive, royalty-free, sublicensable, fully paid, worldwide license to create derivative works from, access, reproduce, distribute, process, publish, display, perform, adapt, modify, analyze, and otherwise use the User Content…”
The license to 'analyze' and 'improve the Descript Service' could encompass AI model training on user content. There is no explicit opt-out mechanism referenced in the visible text.
“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.
“Additional content libraries (the “Additional Libraries”) are not subject to this license, may not be available for commercial use without a license, and may require that you obtain model clearance.”
Additional Libraries outside Storyblocks may require separate commercial licenses and model clearances, creating potential legal exposure for users who assume all platform content is commercially usable.
“ 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…”
“Personalize and improve the Descript Service and for research and development purposes including training our artificial intelligence models;”
User data (including uploaded content) may be used to train AI models. An opt-out exists for Projects specifically, but this broad statement covers other collected information without a clear opt-out.
“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.
“ Scope of License. The license granted to you is limited to a non-transferable license to use the Mac App on any iPhone, iPod touch or iPad that you own or control as permitted by the Usage Rules set forth in the Apple App Store Terms of Service.”
“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.
