Privacy policy
Updated 2026-07-14
We keep data collection small on purpose. Here is exactly what we take, what we never touch, and who processes it.
What we collect
Wallet addresses you scan or monitor. These are public on-chain data.
Your email, if you sign in by email or turn on alerts.
Your Google account id and email, only if you choose Google sign-in.
Your Telegram chat id, only if you connect Telegram for alerts.
Payment records (plan, amount, transaction hash) for paid tiers.
What we never collect
We never ask for your seed phrase or private key. A scan is read-only and needs no signature and no wallet connection.
We do not use advertising or tracking cookies. We do not build ad profiles, and we do not sell or rent your data.
Cookies we set
rad_session keeps you logged in (essential). rad_oauth holds the Google sign-in step and is short lived (functional). NEXT_LOCALE remembers your language (functional).
All of them are functional or essential. Because we set no non-essential cookies, there is no consent banner to click through.
Third parties that process data
Alchemy and public chain RPCs receive the address being queried to return on-chain data. Resend delivers login and alert emails. Google handles optional sign-in. Telegram delivers optional alerts.
Each provider has its own policy. We share with them only what the feature needs to work.
Retention and your rights
We keep account data while your account is active. You can ask us to access, correct, export or delete your data at any time.
To make a request, contact [email protected]. Radarium is not intended for anyone under 18.
