Words to know
Legal words from the lines above, in plain English.
- 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.
- targeted advertising
- Ads chosen for you based on what you have done across other apps and websites, not just this one. For example, you look at shoes in one app and see shoe ads in a totally different app the next day.
- consent
- Your clear agreement to something, given by an action like ticking a box or tapping Accept. For example, a pop-up asking if the app may use your location is asking for consent.
- opt out
- Something is on by default and stays on until you find the setting and turn it off. For example, your chats may be used for training unless you go into settings and switch it off.
- worldwide license
- You let the company use your content anywhere on earth, usually for free and for as long as it likes. For example, a video you post can be shown in ads in any country without asking you again.
- 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.
- 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.
- limitation of liability
- A cap on what the company will ever pay you if something goes wrong, often only what you paid in the last year. For example, if a leak of your data costs you thousands, the most you may get back is a month's subscription fee.
- service providers
- Outside companies that handle your data on the app's instructions, such as a cloud host or an email sender. For example, the company that stores the app's files in the cloud sees your data but only does what the app tells it.
- 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.
