Words to know
Legal words from the lines above, in plain English.
- device identifiers
- Codes that single out your phone or computer, used to recognise you across apps and sites. For example, the advertising ID on your phone lets two unrelated apps know they are seeing the same person.
- personal data
- Any information that is about you or can be linked to you, from your name to your phone's ID. For example, your email, your IP address and the list of apps on your phone are all personal data.
- third parties
- Any company or person other than you and the app, such as advertisers, partners or analytics firms. For example, an analytics company that receives a record of every screen you tap is a third party.
- sell or share
- Under California law, selling means passing your data to others for money or other value; sharing means passing it on for targeted ads. For example, letting an ad network use your browsing history in return for ad space counts as a sale.
- CCPA
- California's privacy law, which gives residents the right to see, delete and stop the sale of their data. For example, a Californian can ask the app to stop selling their data and it must comply.
- retention
- How long a company keeps your data before deleting it. For example, a policy might keep your messages for 30 days after you delete them, or for as long as it likes.
- perpetual
- Lasting forever, with no end date. For example, a perpetual licence means the company can keep using your video years after you leave.
- irrevocable
- Cannot be taken back or cancelled once given, even if you change your mind or delete your account. For example, an irrevocable licence to your photos means you cannot withdraw it later.
- royalty-free
- The company can use your content without ever paying you for it. For example, your photo can appear in the app's ads and you get nothing.
- sublicensable
- The company can pass its rights over your content on to other companies without asking you. For example, an app can let an advertiser or a partner reuse your video under the licence you gave.
- indemnify
- You promise to pay the company's legal costs and losses if your use of the service gets it sued. For example, if you post a song you do not own and the label sues the app, you owe the app's lawyer bills.
- affiliates
- Other companies owned by or connected to the same parent company. For example, if you use one app, its sister apps under the same owner may also get your data.

What does the app collect beyond what it needs to work?
They collect account details and your study content plus device IDs, IP, usage, mouse movements, session replay, and data from ad partners and other third parties.
Does it record your voice, face or body, and what happens to that?
They collect audio files you create or upload as content, and California notices list audio recordings as sensory data they keep with providers. They do not describe voice as a biometric with special opt-in.
Are your chats and uploads used to train AI models, and is that off by default?
Not stated in the documents.

Are you profiled or tracked for advertising?
Third-party ad companies collect data on the service, and Quizlet may turn email or phone into ad IDs used across other platforms.

They say some ad targeting may be a CCPA “sale” or “share,” and you can opt out via Privacy/Cookie Choices or email.
What rights do they take over what you type and what the AI makes?
Posting content gives Quizlet a worldwide, perpetual, irrevocable, royalty-free license with the right to sublicense.
How long do they keep your data after you delete it, and can you delete it in the app?
You can delete your account in Settings, but they keep data while the account is active for business and legal reasons, keep support records indefinitely, and may keep de-identified data forever.
Does it build a lasting memory or profile of you, and can you see, edit or turn it off?
They create and update profiles and audience segments for ads and analytics, without describing user controls to view or turn that off.
Do they commit to basic security, and have they leaked data?
They say they use reasonable industry-standard measures but do not promise the internet is fully safe. No audit or leak history is described.

The service is aimed at 13+, with a restricted Child Account, parental email and consent, and a PRIVO COPPA safe-harbor certification.

The privacy policy is dated, but terms may change without notice, and continued use means you accept privacy changes.

If something goes wrong, who pays?
The service is as-is, liability is capped at what you paid in the prior 12 months, and you must indemnify Quizlet for claims from your use.
