Privacy
Last updated August 2026
- We never ask for your private key or seed phrase. There is nothing for us to leak.
- Connecting a wallet is optional — scanning works without it.
- The only personal data we hold is an email, and only if you give us one.
- We do not sell your data or track you across other sites.
What we read
Public blockchain data, for the address you paste. That is the same information anyone can see on a block explorer — we just read a lot of chains at once and put it in one place.
What we store
- Wallet addresses you paste. Public identifiers, kept so a re-scan is fast.
- Your email, only if you give one. To group your wallets into an account, send your login link, and deliver report links and gift codes. Occasionally a reminder that you have wallets to check — every one has an unsubscribe link.
- Payment confirmations. We read the public transaction to confirm it and keep the reference so your unlock stays unlocked. No card details exist to store.
- Basic technical data. Standard request info like an IP, for rate limiting and keeping the service up. Not used to profile you.
What we never do
Ask for or store private keys or seed phrases. Sell your data. Move your funds. Follow you around other websites.
How long we keep it
Saved reports last a rolling window — roughly 90 days from last use for account reports, and less for anonymous ones — then they are reclaimed. Delete a wallet from your account and its reports go with it.
Your choices
Scan without ever giving an email. Delete any wallet from your account. Unsubscribe from emails in one click. Or email hi@fffonchain.com and we will delete your wallets and their reports, and stop contacting you. Ask us to erase your record entirely and we will do that too — a person handles it, so allow a few days.
Questions
Email hi@fffonchain.com. The rules for using the service are in the terms.
