Privacy
Last updated 27 September 2026
The short version (for kids)
- We keep your email, your username and the worlds you make, so your account works and your worlds are saved.
- Your email is only for checking it's you and helping you get back in. Other players never see it.
- Only friends can message you, and only after you both say yes. Messages are checked for things like phone numbers and addresses.
- When you talk, your voice goes straight to your friends. We don't record it. If you're under 13, there's no voice chat. You can use Words instead, which turns what you say into text on your own computer.
- If you're under 13, we ask for a grown-up's email, not yours, and your account starts working once they say yes.
- No ads. We don't sell anything about you, and we don't track you around the internet.
- You or a grown-up can delete your account and everything in it at any time.
Who we are
Worlds is run by Danny Bradley, Texas, United States. Questions, or requests about your data or your child's data: dannybradley@protonmail.com.
Children
Worlds is made for children and families. Everyone who signs up is asked the month and year they were born. If a child is under 13:
- We ask for a parent's or guardian's email, never the child's own. We email the parent to explain Worlds and what their child can do, and the account only works once the parent opens the link in that email.
- No voice chat. The child can talk in "Words" mode instead. Their speech is turned into text on their own computer (no audio leaves it), and each whole sentence is checked before anyone else sees it.
- Messages and chat go only to friends added with a private friend code. Anything that looks like an email address, link, phone number or street address is removed before it is shown to anyone.
Parents can ask to see, change or delete everything we keep about their child, and can stop us keeping more, by deleting the account (Your account → Delete my account) or by emailing us. We only collect what we need to run the game. A child never has to give more to take part.
What we keep, and why
| What | Why | Who can see it |
|---|---|---|
| Email address (for an under-13, the parent's) | To check the account is real (for an under-13, to tell the parent and get their go-ahead), and to send a link if the password is forgotten. Nothing else: no newsletters. | Nobody but us |
| Birth month and year (never the day) | To know whether the player is under 13, which changes what the account can do | Nobody but us |
| Username and player name | So friends can recognise you | Other players, and anyone who sees a game you publish |
| Password | To sign in. Stored only as a scrambled hash: we cannot read it. | Nobody |
| Friend code | So a friend can add you (on the website you can't be added by name). You can change it any time. | Whoever you give it to |
| Friends, friend requests, blocks | So only friends can message and invite you | You, and the friend involved |
| Messages between friends | So you can read them. A message containing an email, link, phone number, address or blocked word is refused and never stored. | You and that friend |
| Your worlds, character and lobby | So they are saved online and there on any computer | You. Friends see what your planets look like, not what's inside them. |
| Games you publish, with stars and plays | So other people can find and play them | Everyone on Worlds |
| Reports | If a player reports someone: who, about whom, and one of a few fixed reasons (no free text) | Us |
| Explorer level | Shown to your friends | Your friends and your party |
What we don't keep
- Voice. Voice chat goes directly between the players in a party or world. When a direct connection isn't possible it passes through our own relay server, which forwards it and records nothing.
- "Words" mode. Speech is turned into text on your own computer. Only the text is sent, it is checked the same way as messages, and it is shown and then gone. It is not stored.
- Webcam. If you turn on the camera to move your character, the video stays on your computer. Only the movement of your character is sent to the people with you, and it is not stored.
- Tracking. No advertising, no analytics services, no tracking pixels, no selling or sharing of data for marketing.
Cookies and your browser
We use one cookie, to keep you signed in. Your browser also stores your settings and the world you are working on. None of this is used for tracking.
Who else handles it
These companies handle data on our behalf, only to run Worlds:
- Vultr hosts our server in the United States (New York).
- Resend sends the sign-up and password emails, so it receives your email address and that email.
- Anthropic, only if the building helper "Spark" is switched on: what you type to Spark is sent to Anthropic's AI to build your game. It is not used to train their models.
- If our server doesn't have the webcam files, your browser downloads them from jsDelivr and Google. That download is only files; no pictures or video are sent.
How long we keep it
Everything is kept until you delete it or delete your account. Invites run out after 10 minutes. When you delete your account (Your account → Delete my account), your account, player, worlds, published games, friends, messages, invites, reports and level are deleted straight away. Copies in our server's backups are replaced over time and are gone within [BACKUP PERIOD, e.g. 30 days].
Keeping it safe
The site uses HTTPS only. Passwords are hashed, and sign-in and email links are stored only as hashes. Guessing is rate-limited. Only friends can message or invite each other. On the website a party or world lets in only the people invited to it.
Your rights
You or your parent can see, correct or delete what we keep, or ask us to stop. Most of it you can do yourself in the game. For anything else, email dannybradley@protonmail.com and we will answer within 30 days. Depending on where you live (the UK or EU, or California, for example) you may also complain to your data protection authority.
Changes
If we change this policy, we'll update the date at the top. For a big change we'll tell you in the game, and ask parents again where the law requires it.
