Staying safe in Hydrogen Line

How to block, report and keep your details private, what happens when you report, and where to get help. There's a section for parents and guardians too.

Six things to know

Keep your details private

Never share your real name, address, school, phone number or photos with players you don't know in real life.

The game won't let anyone post phone numbers, email addresses, links or social media usernames.

Block anyone

Block stops a player messaging you, sending you friend requests, trade offers or invites, and hides their alliance chat from you. They aren't told.

Under 18? You choose who messages you

Friends, your alliance and players you've written to can message you. Anyone else sends a chat request: you see who it's from, and choose whether to read it.

Report it

Use Report on a message, a chat line, a profile, a planet's name or an alliance, or open Moderators in the game.

The player isn't told about your report, or who sent it.

You choose your alliance

Nobody can put you into an alliance or its chat. You join by choosing to, by applying, or by accepting an invite, and you can leave whenever you like.

Know the warning signs

If someone asks how old you are, where you live, for photos, to keep a secret, or to talk on another app, stop replying, block them and report it.

Tell a parent or an adult you trust. Nobody from Hydrogen Line will ever ask for your password.
