Effective 2026-08-25
Tanzory turns a public Ethereum wallet address into a shareable rank card, using public on-chain data. This page explains what data we collect when you use it, why, and how long we keep it.
The wallet address you scan. This is public blockchain data — anyone can look up any wallet's transaction history without our help. Scanning is free and unlimited; there's no payment, signature, or identity involved. We fetch and store on-chain statistics about the address (transaction count, gas spent, token holdings, NFT activity, active spending approvals) via Moralis, a third-party wallet-data provider.
Promoted leaderboard messages. The only paid feature is promoting a message on the "Most Promoted" leaderboard. If you do this, we store the message text you write, the amount paid, how many days it runs, and (if you used one) a referral code. We do not store which wallet paid — payment itself is handled by NOWPayments, a third-party crypto payment processor; we never directly receive or hold your funds.
IP address, briefly. Requests are checked against a short-lived, in-memory rate limit to slow down abuse. This isn't written to a database or kept after the check.
What we don't store: we don't use tracking cookies, we don't run analytics scripts, we don't collect your name or email, and there is no account system — nothing ties a scan or a promoted message back to a person.
Today: indefinitely. Scans, and promoted messages (even after they expire off the visible leaderboard), stay in the database with no automated deletion process and no self-service way to request removal. Contact us (see below) and we will handle a removal request manually until a proper deletion flow exists.
We use a small number of third-party services to run Tanzory, each of which processes data as part of providing their service to us:
Each of these providers has its own privacy policy and may log requests (e.g. IP addresses) as part of normal infrastructure operation, independent of this app.
Depending on where you're located, you may have rights to access, correct, or request deletion of data associated with your address. Contact us to make a request — see below. (We are still finalizing the formal process for this; reach out and we'll handle it directly in the meantime.)
Any material changes to this policy will be reflected here with an updated date.
