Words to know
Legal words from the lines above, in plain English.
- human review
- Company staff or contractors may read your messages or content, usually to check for rule breaking. For example, a flagged private chat with an AI can be read by a person at the company.
- as is
- You get the service in whatever state it is in, with no promise that it works or will keep working. For example, if the app deletes your photos by mistake, it is not promising to fix that or pay you back.
- warranty
- A promise that a product will work as described; most apps say they make no such promise at all. For example, if a paid feature never works on your phone, a no-warranty clause says that is your problem.
- 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.
- 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.
- cookies
- Small files a website saves on your device so it can recognise you and remember what you did. For example, a cookie keeps you logged in and can also tell an ad company which sites you visited.
