Data, Retention & Integrity

What we keep

  • One sign-in cookie, in your browser: your wallet address and your token balance. It lasts up to 7 days, or until you sign out.
  • Our host keeps short-lived technical logs, like every website, including error messages so we can fix problems.

What we don't keep

  • No database, no accounts, no tracking, no ads.
  • Nothing about you on our servers beyond those logs.

What is public anyway

Transactions you approve are recorded on the Solana blockchain, which is public and permanent. Nobody can delete them.

How your balance stays accurate

  • The gate always reads your token balance from the Solana blockchain on our server. It never trusts a number sent by your browser.
  • Your session cookie is cryptographically signed. Editing it from outside invalidates it.
  • Your balance is re-checked every few minutes, not just once at sign-in.
  • If the Solana RPC doesn't answer, the app fails closed — it tells you it couldn't verify your balance rather than letting you in anyway.
  • Every transaction appears in your wallet before you approve it, and afterwards anyone can look it up on a public Solana explorer such as Solscan.

How to delete your data

  • Sign out. That clears your session cookie right away — there is nothing else of yours to delete.
  • Or clear your browser's cookies for this site, which does the same thing.
