Ursa Ledger
Privacy Policy
This is a plain-language starting draft and has not been reviewed by a lawyer.
Last updated November 13, 2026, Eastern Time.
This policy explains what information Ursa Ledger collects, what is public, and how you can ask questions or request deletion. It covers the Ursa Ledger hub and the games and classroom pages linked from it.
What we collect
If you play without creating an account, we generally do not ask for your name or email. A game may still use a public testnet wallet address, and if you choose to save a score or a picture, a memo with your nickname and score can be written to the public XRP Ledger testnet.
If you create a Star Cub account, we collect the email you use to sign in. We may also keep the nickname, scores and votes you choose to save, and the public testnet wallet addresses and memos connected to that play.
If you join the optional email list for The Den, Kit collects the email address you submit for that list.
What is public
Nicknames, scores and on-ledger memos can be shown on public leaderboards and in public testnet explorers. Data written to the XRP Ledger, including testnet, is public and permanent. Anyone can read it. Do not put personal details in a nickname or a memo.
What we never collect
We never collect birth date, birth time or birth place in Ursa Ledger or its games. We never ask for a wallet seed or secret. We never collect payment cards, bank details or other payment information in Ursa Ledger.
Processors
We use a few services to run the site:
- Supabase, for Star Cub login and related data.
- Kit, for the optional email list.
- here.now, to host the sites. Like most hosts, it may process technical data such as IP addresses in order to serve the pages.
Those services have their own privacy policies. We use them to operate Ursa Ledger, not to sell your information.
Cookies and localStorage
We use localStorage in your browser to remember that you accepted the legal notice, and sometimes to keep game settings or a session. If you sign in or join the optional email list, Supabase or Kit may set cookies needed for that login or form. We do not use advertising cookies, and we do not sell your personal information.
Deletion requests
You can ask us to delete your Star Cub account and the off-ledger data we keep by emailing hello@astrobear589.com. We will do what we can. Data already written to the XRP Ledger cannot be deleted, because a public ledger does not allow that. We can still remove or hide the same information from our own sites where we control the display.
Children under 13 are not allowed
Ursa Ledger is not directed at children under 13. You must be 13 or older to use it. If you are a parent or guardian and think a child under 13 has given us personal information, please email us and we will delete the off-ledger information we can delete.
California, EU and UK rights
If you are in California, you may have the right to know what personal information we have collected, to ask us to correct it, and to ask us to delete the off-ledger information we can delete. We do not sell personal information or share it for cross-context behavioral advertising.
If you are in the European Union or the United Kingdom, you may also have the right to access a copy of your personal data, ask us to correct it, ask us to delete or restrict certain off-ledger processing, object to certain processing, and lodge a complaint with a data protection authority. Some of these rights do not apply to information that already lives on a public ledger, because we cannot change or erase that record.
To use any of these rights, email hello@astrobear589.com. We may need to confirm it is you before we fulfill a request.
