Privacy policy
Sentinel works with public blockchain data and keeps very little about the people who use it. This page lists exactly what the hosted service stores and why.
What we do not collect
- No accounts, names, emails or passwords
- No private keys or seed phrases, ever
- No cookies, no analytics or tracking scripts, nothing kept in your browser
What is stored
| Data | Why | How long |
|---|---|---|
| Decision log: wallet address, a short summary of the request, the decision and its reasons | So owners can see why a wallet said no. Public through /api/journal. | Kept |
| IP address with a request counter | Rate limiting, 30 requests per minute | Up to 24 hours |
| Telegram chat id linked to a guarded wallet | To send approvals, blocks and freeze alerts | Until you send /stop |
| Freeze state of a guarded wallet | The kill-switch must hold until the owner unfreezes | Until unfrozen |
| Token scan results | Cache, so repeated scans are fast | Reused for 60 seconds |
| Daily call counts per endpoint, without IPs or wallets | To see load and errors | Kept |
The hosting provider also keeps short-lived request logs, which include IP addresses, for operating and debugging the service.
Services that receive data
To answer a request Sentinel sends token addresses, wallet addresses and transactions to:
- Helius, the Solana RPC provider, for on-chain data and simulations
- Jupiter, for quotes, swap routes and prices
- DexScreener, for market data
- Telegram, for bot messages you opted into
- The token's own metadata links, for example IPFS gateways
The service runs on Vercel and stores data in a Neon Postgres database. The website loads fonts from Google Fonts, which receives your IP address.
Blockchain data is public
Everything Sentinel analyses is already public on Solana. Transactions you sign and send become public and permanent on-chain, independently of Sentinel.
Your choices
- Send
/stopto the bot to unlink your chat. - Run Sentinel yourself from the open-source code if you do not want to use the hosted service at all.
- To ask about or remove data tied to your wallet, open an issue on GitHub.
Changes
If what we store changes, this page changes with it, and the date at the top is updated.
