Privacy Policy
Last updated: 24 September 2026
OneBlock is a non-custodial app. It has no accounts and never asks who you are. This policy explains the little information that is involved when you use it.
1. The short version
- No account, name, email or identity check.
- No tracking cookies and no analytics.
- We never see your private keys or hold your funds.
- Your wallet address and on-chain activity are public on the blockchain, by the nature of blockchains.
2. Your wallet
When you connect a wallet, it shares your public address with the app in your browser so it can show balances and prepare transactions. Your private keys and seed phrase never leave your wallet.
3. On-chain data
Launching or trading creates public blockchain transactions: wallet addresses, amounts, the coin's name, ticker and image, and timestamps. This data is public and permanent. Nobody, including OneBlock, can edit or delete it.
4. Server logs
Our web server records standard request logs (IP address, time, requested page, browser type) for security and to keep the site running. They are kept only as long as needed for those purposes and are not used to build profiles.
5. Browser storage
The app stores a few settings in your browser: your selected network, a launch you have reserved but not finished (including the secret needed to finish it), and that you have seen the storage notice. They stay on your device. See the Cookie Policy.
6. Services your browser talks to
To work, the app connects from your browser to: the public RPC endpoints of Robinhood Chain and Arc, which read the blockchain and receive your signed transactions; Coinbase's public price endpoint, to show values in US dollars; and your wallet software. These services receive technical data such as your IP address under their own privacy policies. Fonts are served from our own server.
7. We don't sell data
We do not sell or share personal information for advertising.
8. Your choices and rights
You can clear the app's browser storage at any time, disconnect your wallet or stop using the app. Depending on where you live, you may have rights to access, correct or erase personal data we hold. We hold very little, and on-chain data cannot be erased by anyone.
9. Children
The Service is not meant for anyone under 18, and we do not knowingly collect data from children.
10. Changes
We may update this policy. Changes are shown by the "Last updated" date above.
