Fukuro Privacy Policy

Last updated: 2026-10-16

Fukuro is a Chrome extension that shows the risks of coins on pump.fun. This page explains what data is kept, where, and why.

Your wallet and your money

  • Fukuro never connects to your wallet, never asks you to sign a transaction, and never asks for your seed phrase or private key.
  • You send the Premium payment yourself from your own wallet. Fukuro verifies it from the public records of the Solana network.

Kept only in your browser

  • Your settings (language, theme, risk rules), the coins you watch and the wallet addresses you follow are stored in Chrome's extension storage. If Chrome sync is on, they move to your other Chrome browsers on the same Google account. This data is not sent to Fukuro, except for the parts Premium features need, described below.

Data sent to the Fukuro server

  • License code: A random code generated by the extension. Your name, email or other identity details are never requested.
  • Device code: A random code generated for each installation. It is stored with a last-seen time so that one license can be used on at most 3 devices.
  • Free trial limit: To stop unlimited trials from the same internet connection, a one-way hash of your IP address is kept for 30 days. The IP address itself is not stored.
  • Payment records: The chosen plan, amount, currency, the payment's transaction signature and the sending wallet address. These are already public on the Solana network; they are kept to prevent the same payment from being used twice and to provide support.
  • Premium requests: While Premium is active, the address, name and symbol of the coin you view, the coin's X link and the public addresses of wallets you follow are sent to the server to compute the results. These requests are not stored; the server only uses a short-lived cache.

Third parties

  • Coin data comes from pump.fun's public services, X account details from FxTwitter, and payment verification from Solana network services. Only information such as coin addresses, X usernames or public wallet addresses is sent to them.
  • The server and this website run on Cloudflare, which may technically keep connection logs. This website has no ads or trackers.
  • None of the data is sold, used for advertising or shared with others.

Deletion

Removing the extension deletes the data in your browser. To have your license and device records deleted from the server, email support@fukuroapp.com and include your license code.
