FantomApp: practical tools to maintain control over your data
The CNIL supports 10- to 15-year-olds with FantomApp, an app to help teenagers protect themselves on social media.
Young people themselves were the inspiration for the creation of FantomApp, which was designed to meet the specific requirements they have expressed with regard to the protection of their personal data.
FantomApp is about:
- tools and tutorials to help you protect your accounts and “clean up” your online presence
- advice and content to help you if you encounter any problems
- a free and secure application that does not collect any data (except for the IP address, which is necessary for the application to function, and the type of device used).
FantomApp is available free of charge from App Store and Google Play and directly from its web version: fantomapp.org

You can blur and pixelate your profile picture to remain anonymous on social media.
