The license grant over user inputs is irrevocable, worldwide, royalty-free, and sublicensable—meaning Cohere retains these rights even if the user terminates their account. The scope is extremely broad.
“By submitting Content or any other material to Quizlet for inclusion on the Service or for any other purpose, for example posting a flashcard set, answering a survey or sending Quizlet an email, you grant Quizlet a world-wide, perpetual, irrevocable, royalty-free license (with ri…”
Users grant a perpetual, irrevocable, royalty-free, sublicensable license over all submitted content — including inputs like flashcard sets and emails — with no compensation and covering all existing and future media. This is an extremely broad rights grab.
“ The Cohere Solution and all materials provided by us hereunder are made available or licensed and not “sold” to you. ”
“14. **Trademarks.** Quizlet, Quizlet.com, Quizlet Ads, the Quizlet mark and logo, and all other trademarks, service marks, graphics and logos used in connection with Quizlet, or the Service are trademarks or registered trademarks of Quizlet or Quizlet's licensors. Other trademark…”

Cohere uses Trial and Research user inputs and outputs for model training/improvement under 'legitimate interests' rather than consent, giving users limited ability to object. Paid/Enterprise users may have different treatment but this is not clarified here.
“you grant Quizlet a world-wide, perpetual, irrevocable, royalty-free license (with right to sublicense through multiple tiers) to use, copy, reproduce, process, adapt, modify, publish, transmit, publicly display, publicly perform and distribute such Content or material in any and…”
The broad license to 'process' and 'adapt' submitted content, combined with the 'additional uses' catch-all and sublicensing rights to partners, is broad enough to encompass AI/ML training use. No explicit opt-out is provided.
“you further represent and warrant to and covenant with Cohere that you will not (and will not attempt to) directly or indirectly: disable, overly burden, impair, or otherwise interfere with servers or networks connected to the Cohere Solution (e.g., a denial of service att…”
Commercial exploitation of the Cohere Solution itself is prohibited without prior written permission, which significantly restricts resale, white-labelling, or embedding scenarios.
“ 4. **Restrictions**: You may not use Premium Content for any commercial purpose. This means you can’t sell it, use it for advertising or marketing purposes, or use it in any other way in connection with a business or profit making activity. You may not post or otherwise make…”
“The use of cookies for this purpose may be considered a “sale” or “sharing” under California privacy law.”
Platform acknowledges its advertising cookie practices may constitute a 'sale' or 'sharing' of personal data under CCPA/CPRA.
“We retain records of support tickets and other communications between Quizlet and our users, for example support emails, survey responses, feedback submissions, or comments on our blogs or other posts, indefinitely in order to better manage our support processes, maintain accurat…”
Support communications are retained indefinitely AND Quizlet reserves the right to publish them publicly; users submitting support requests may not be aware their communications could be published.
“EXCEPT FOR ANY SPECIFIC WARRANTIES OR CONDITIONS PROVIDED IN AN APPLICABLE SUBSCRIPTION AGREEMENT OR AS OTHERWISE REQUIRED BY APPLICABLE LAW”
Warranty and other protections may differ for users with a separate Subscription Agreement (typically paid/enterprise tiers), but the specific differences are not disclosed in this document.
“01. **Eligibility.** Use of the Service is void where prohibited. The Service is intended for users over the age of 13, but is open to all ages. For children age 13 or younger (or other age of consent where required by local law), Quizlet offers a restricted feature set and websi…”
