Cookie Policy
Last updated: 24 September 2026
OneBlock sets no tracking cookies and runs no analytics. The app only keeps a few settings in your browser's local storage so it works as you expect.
1. What we store
| Key | Purpose | Kept |
|---|---|---|
| ob_chain | The network you selected | Until you clear it |
| ob_pending:* | A launch you reserved but haven't finished, including the secret needed to finish it | Until the launch completes or the reservation expires |
| ob_cookie_consent | That you have seen the storage notice | Until you clear it |
None of these contain your identity, keys or funds. Your wallet extension manages its own connection state.
2. Managing it
You can delete these entries at any time by clearing this site's data in your browser settings. If you clear an unfinished launch, you can't finish it; you can start a new one.
3. Third parties
Your wallet, RPC providers and block explorers may use their own storage when you interact with them, under their own policies.
4. Changes
We may update this policy. Changes are shown by the "Last updated" date above.
