VANISH extension

Privacy policy

Last updated 20 October 2026 (version 0.2: trading wallet, trades, sync). This covers the VANISH browser extension: the card it shows on Solana token pages and its toolbar popup. Website: vanishwallet.tech.

What the extension reads

On Solana token pages of dexscreener.com, dextools.io and pump.fun: only the address of the page, from which it takes the token or pair address. On x.com: the text of posts on your screen, read inside your browser only to spot Solana token addresses; the text itself is never sent anywhere, only an address it finds. It does not read the rest of any page, your other tabs, or anything you type, except an address you paste into its popup.

What it sends, and to whom

• To vanishwallet.tech (our server): the address of the token on screen, so we can answer with that token's launch data. Nothing else is attached: no account, no wallet, no identifier of you.
• To api.dexscreener.com (DexScreener's public API): when a page shows a trading pair, the pair address, to learn which token it is. DexScreener's own privacy policy applies to that request. It also asks DexScreener for the token's live market cap while its card or badge is on screen.
• To api.geckoterminal.com (GeckoTerminal's public API): the address of the token's pool, to draw the last hour's price chart. GeckoTerminal's own privacy policy applies.

Like any request on the internet, these carry your IP address. Our server and our hosting provider keep standard request logs, used only to keep the service running and to stop abuse, and never linked to anything else.

The trading wallet inside the extension

• Made and kept on your device. When you create a wallet, its key is generated in the extension and encrypted on your device with your passphrase (PBKDF2 with 600,000 rounds, then AES-256-GCM). The key and the passphrase never leave your device in readable form: not to our server, not to the page you are on.
• Unlocked only in memory. While unlocked, the key is held in the extension's session memory, which only the extension itself can read. It locks 30 minutes after the last unlock or trade, and when the browser closes.
• Trades. A trade happens only after you click twice on the card. The extension asks api.jup.ag (Jupiter) for a route, signs on your device, and sends the transaction to Solana through our RPC proxy at vanishwallet.tech. Each swap pays a 0.5% VANISH fee in SOL inside the same transaction, to an address specific to your trading wallet.
• Sync with vanishwallet.tech. If you use the website too, you can share the same wallets between the two. A sync starts from vanishwallet.tech and happens only after you confirm on the extension's own page; the wallets travel encrypted, and only between the extension and vanishwallet.tech.
• Your responsibility. If you forget the passphrase and have no exported key or synced copy, the wallet cannot be recovered. We cannot reset it.

What it does not do

• No browsing history: it never records or sends which pages you visit, apart from the token address described above, at the moment you are on that page.
• No access to your other wallets: it never connects to, reads or signs for Phantom, Solflare or any wallet you already have. It only uses the trading wallet you create inside it.
• No accounts, no cookies of its own, no ads, no analytics, no remote code.
• We do not sell, rent or share any data, and we do not use it for anything other than showing you the card.

Stored on your device

In your browser's extension storage: your trading wallet's encrypted vault (unreadable without your passphrase), your DRY or LIVE choice, whether you collapsed the card, and short-lived copies of recent answers (cleared when the browser closes) so the same token does not need to be asked for twice.

Chrome Web Store Limited Use

The use of information received from Google APIs and the browser follows the Chrome Web Store User Data Policy, including the Limited Use requirements. Data is used only to provide the extension's single purpose: launch information and trading for the Solana token on the page.
