Your data

Taxinger reads public records and your own uploads. It never holds anything that can move your money.

Read-only, always

Only public addresses. No keys, no seed phrases, no exchange API keys: an exchange comes in as the statement you download yourself. Signing a message to prove an address is yours moves nothing and approves nothing.

There is nothing in Taxinger that could spend from a wallet: no key to sign with, and no approval of yours to use.

Signing in

An email link, a signature from your wallet, or Telegram, whichever you prefer, and several of them can belong to one account. Passkeys are the second factor on top, with recovery codes behind them, and a passkey is required where an account reads somebody else's tax data.

Sessions are server-side and can be ended; nothing about your sign-in lives in a token in your browser that we cannot revoke.

What is held

The chain data itself is public and is held once for everybody who watches an address, not per person. What is yours is the link between you and the addresses you watch, your uploaded statements and their rows, your answers and notes, and the years computed from all of it.

Your language and your tax country are settings on your account. There is no profiling and no advertising: visits are counted without storing anything in your browser (the cookie notice says exactly how), and no model is ever asked what your transactions were. The one exception is the layout of an exchange's statement, read once per exchange from its column names and a few examples with the values masked.

What is held about you, for how long, and on what legal basis is set out in the Privacy Policy, with the cookies in the cookie notice.

Deleting it

You can delete the account, and it is yours alone to delete, not your accountant's. What goes with it is everything that was about you; the public chain records stay, as they are nobody's personal data and belong to no account.

One case cannot be honoured on request: while a subscription bought inside the iOS app is live, the account cannot be deleted, because Apple gives a seller no way to cancel it for you. Cancel it in your Apple account first, and the deletion goes through.
