“ 5.1 The Service is made available on a limited access basis, and no ownership rights are conveyed to you. Notwithstanding anything to the contrary in these Terms, we and our licensors have and retain all right, title, and interest, including all intellectual property rights, in…”
“ Sign up and log-in to your account may be done with your email address or by means of some social logins. Any terms and conditions in relation to the email service or social login that you use are from theirs and they have nothing to do with our terms and conditions. ”
“ 15. “AI Application” means a software capability built by the user through the Service provided by Dify, incorporating artificial intelligence, machine learning, or similar technologies.”
“To provide our Services (such as storing your content in our cloud and sharing the content in the Community Content Hub, as well as maintaining, operating, exploiting or advertising the Hub and any other products or services offered by us, our licensors, partners or related compa…”
Although users retain ownership, the license granted is perpetual, irrevocable, sublicensable, worldwide, and covers derivative works, marketing exploitation, and sharing with third parties and APIs — extremely broad.
“Operate, maintain and improve our internal operations, systems, Sites, and Products”
The policy does not explicitly address whether user content is used for AI/ML model training. 'Improve Products' could encompass training use, but this is not confirmed or denied.
“Operating and improving Voicemod Products, so that they can work as designed and can maintain the ever-improving nature of our technology, for example, to prevent or address malware or illegal content, or to develop them to offer you better quality sounds or voices, better adapt…”
User content may be used to improve and develop Voicemod's technology, which includes AI/ML models, as part of the broad perpetual license grant. This effectively permits training use.
“ 2.1.1 LangGenius (and its Affiliates, as applicable) will make the Services available to you, including those described in the applicable Services Terms 2.1.2 You may use your Dify.AI Account and the Service only (i) for lawful purposes; and (ii) in accordance with these Terms…”
“you expressly authorise Voicemod, on a non-exclusive basis, free of charge, worldwide and without time limitation, to use your comments, feedback and/or testimonials for any purpose (including commercial), including any photograph, image, text and/or video forming part thereof, i…”
Users grant Voicemod a perpetual, worldwide, free-of-charge license to use their testimonials, feedback, images, and likeness for any commercial purpose without limitation.
“We use this information to reshare content created through the use of the Service. The processing is necessary for our legitimate interests (to develop our service and inform our marketing strategy).”
Information from social network interactions can be reshared by LangGenius for marketing strategy purposes under a 'legitimate interests' basis without explicit user consent.
“You also acknowledge and agree that User Content, once uploaded to the Community Content Hub, may be downloaded by other users to create more content and that, accordingly, even if you subsequently delete any content, it may continue to be used by those users who downloaded it du…”
Deletion of content does not guarantee removal; content downloaded by other users may continue to circulate indefinitely. Combined with the perpetual irrevocable license, effective deletion is practically impossible.
“Dify is free for students and educators.”
No terms or conditions are specified for the student/educator free tier—it is unclear whether it matches the Sandbox tier, has separate restrictions, or requires verification. Users cannot assess their rights or obligations from this statement alone.
“ 3. We may also provide technical support for the use of Voicemod Products and/or Voicemod Content, with limitations, especially in the cases of discontinued Products and old versions of our Products, Services and/or Technology. ”
