Privacy policy

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.

Sponsor slots are sold directly and approved by hand. They are labelled SPONSORED. To avoid showing you the same sponsor too often, your browser keeps a small local count in localStorage. That count never leaves your browser and carries no identifier, so it cannot be used to profile you.

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.

Separately from cookies, we use localStorage for one thing: counting how often a sponsor slot has been shown to this browser today. It stays on your device and is never sent to us.

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.
