Privacy Policy

The short version

Blockchains.Click doesn't ask for your name, email, or a password. You sign in by signing a message with your Solana or EVM wallet — we store the public wallet address that produces, not any identifying information tied to it. This page explains exactly what is collected, why, and who else sees it.

What we collect

• Wallet addresses. Your Solana public key (used for sign-in) and, if you use one, an EVM address you've pasted or connected as a destination. Both are public on-chain data, not secrets.
• Swap and purchase records. Quotes, transaction status, and amounts for swaps and NFT purchases you make through the app — needed to actually deliver what you paid for and to credit points.
• Points and referral data. Your points balance, referral code, and which wallet referred which.
• A session cookie. An HttpOnly cookie holding a signed token that proves you own the wallet you signed in with — it doesn't contain a password or private key (this app never sees your private key or seed phrase, full stop).
• Basic analytics. Google Analytics (GA4) and Vercel Analytics — standard page-view/traffic data, not tied to a wallet address.

What we don't collect

No name, email, phone number, government ID, or KYC documentation. No private keys or seed phrases — every transaction is signed in your own wallet, never by us. We don't sell personal data, because we don't have the kind of personal data that gets sold.

Who else sees it

Executing a swap or purchase means the relevant amounts and destination address necessarily pass through the engine that executes it:

• Jupiter and Relay for Solana/EVM swaps and NFT purchases — both non-custodial; they never hold your funds, only route a wallet-signed transaction.
• ChangeNOW for Bitcoin and Sui swaps specifically — a real, separate exchange. Unlike Jupiter/Relay, this leg is custodial: your deposit briefly sits with ChangeNOW before it delivers the destination asset. See how a ChangeNOW-routed swap works for the full mechanics.
• Supabase hosts the database (wallet addresses, swap/points records) and issues the session token. Vercel hosts the app itself and its own analytics.

None of this data is sold to third parties. It exists to make the app function and to credit points correctly.

On-chain data

Every transaction you sign is public and permanent on its own blockchain, independent of anything this app stores — that's true of any wallet-based app, not specific to us, and it means on-chain history can't be deleted even if you ask us to delete your off-chain account data.

Your choices

You can stop using the app at any time — nothing persists beyond your wallet address and transaction history in our database. Reach out via @blocksdotclick if you want your off-chain account record (points/referral data, not on-chain history) deleted.
