What we store
When you create a character we store your game data, like your captain's name, ships, crew, gold, cargo and log book, in a database hosted on Google Firebase. You don't need to give us your real name, email address or phone number.
Cookies
We use one cookie to remember your player ID so you stay signed in. If you sign in with a passkey, we store the public part of the passkey and use a short-lived cookie during sign-in. We don't use advertising or tracking cookies.
Analytics
We use Vercel Web Analytics and Speed Insights to count anonymous page visits and measure how fast the game loads. They don't use cookies and don't identify you personally.
Sharing
We don't sell or share your data with anyone. It's only processed by the services the game runs on, which are Vercel and Google Firebase.
Children
The game is set in the 17th century and includes references to alcohol and tobacco. It doesn't knowingly collect personal information from anyone, including children.
Deleting your data
No personal information is asked for when you register, so your character can't be linked to you. You can stop playing at any time. If you want your character deleted, open an issue on GitHub and we'll remove it.
Changes
We may update this page now and then. The date at the top shows when it last changed.
