3018 is an iPhone application developed by Association e-Enfance. It serves as the national helpline for victims of online harassment and violence. With this app, users can reach out to professionals via chat or phone, who listen without judgment and provide support to stop the abuse.

One of the key features of 3018 is the ability to keep a record of harassment incidents and store evidence securely in a digital safe. Users can submit these proofs to 3018 when they feel ready, allowing the professionals to take appropriate action. The app ensures the security of the stored data and can even have harmful content removed within an hour.

To help users identify if they are being harassed, 3018 offers a "Am I being harassed?" quiz. This quiz educates users about the different forms of harassment and encourages them not to minimize their experiences and to seek help rather than face it alone.

In addition, the app provides notifications to keep users informed about new ways to protect themselves on social media platforms. It also offers advice sheets to help users understand their rights and learn how to respond in such situations.

3018 is a free utility and tools app available on the iPhone platform. It aims to provide a safe space for victims of online harassment and violence, offering support, resources, and guidance to help them navigate through these challenging experiences.
