“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.
“**7.2** Subject to your Consumer Law Rights, the Generated Content is provided “as is” without warranties of any kind, either expressed or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, title or non-infringement. We disclaim…”

By default, user content is used for model training. Opt-out requires a paid subscription and use of the private generation mode — free-tier users have no opt-out.
“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.
“- our [privacy policy](https://leonardo.ai/privacy-policy) and our [data processing addendum](https://leonardo.ai/data-processing-addendum) (on our website) which each set out how we handle the Personal Data of our users and commercial customers (as applicable);”
“ 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…”
“**10.5** You must only disclose Personal Data to us if you have the right to do so (such as having the individual’s express consent).”
“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.
“With a paid subscription, you have control over who can see your generated Content. When you use private mode, your generated Content cannot be accessed or used by other users. If private mode is turned off, your Content is considered public and can be accessed and used by other…”
Free-tier users have no privacy controls: all generated content is public by default, indexed by search engines, and accessible to other users. This is a significant tier-based privacy disparity.
“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…”
