Key points
- rxn.gg sets no advertising or social-media cookies and runs no third-party analytics; `rxn_trader` is a first-party attribution cookie (see Consent). No third party sets cookies through its pages, except the two noted under Third parties.
- It uses four cookies at most: your language, a trader mark, a sealed session for predictions, and the operator’s own admin session.
- Most of what the Interface remembers — practice, settings, layouts, favourites — is kept in your browser’s local storage and never sent to us.
- You can delete all of it by clearing the site’s data in your browser.
1What cookies and local storage are
A cookie is a small file a website stores in your browser and that the browser sends back with each request to that site. Local storage and IndexedDB are similar stores in your browser that the site’s own pages can read, but that are not sent with requests. This policy covers both. It is part of our Privacy Policy.
3Browser storage
The Interface keeps the following in your browser’s local storage or IndexedDB. These are read only by rxn.gg’s own pages; except where the table says so, nothing in them is sent to us.
| What | Keys | Purpose |
|---|---|---|
| The RXN key | IndexedDB — the site’s own store for the key (in the desktop app, the operating system’s secure store) | Your trading key, encrypted under a key your browser will not export. Never sent anywhere; it signs the orders that go to Hyperliquid. If your browser cannot encrypt it (for example, because storage is full), the key is kept in local storage without encryption until it can. |
| Trading on this device | `rxn.key.*`, `rxn.ticket.*`, `rxn.hotkeys.*`, `rxn.twaps.*`, `rxn.chases.*`, `rxn.grids.*`, `rxn.guard.*`, `rxn.dexes.*`, `rxn.deposit.*`, `rxn.withdraw.*` | The RXN key’s period and approval records (not the key itself), confirmations you gave in the ticket, hotkeys, running TWAP, chase and grid orders, Guard settings, the list of Hyperliquid venues, and the deposit and withdrawal routes you used last. |
| Wallet and connection | `rxn.wallet.*`, `rxn.wc.*` | Which wallet you connected, so it reconnects. |
| Practice | `rxn.practice.*` | Your practice balance, positions, grids and prediction tickets. |
| Settings and layout | `rxn.settings.*`, `rxn.view.*`, `rxn.lock.*`, `rxn.desk.*`, `rxn.chart.*`, `rxn.windows.*` | Your choices: confirmations, sounds, number format, chart look, the layout of the terminal and windows. |
| Markets | `rxn.favourites.*`, `rxn.picker.*`, `rxn.predictions.*`, `rxn.screener.*`, `rxn.listings.*`, `rxn.spot.*`, `rxn.alerts.*` | Favourites, the market picker’s sort, tab and columns, saved predictions, the screener’s recent history, new listings already seen, price alerts set in this tab. |
| Campaign tag (attribution) | `rxn.ref.*` | The tag of the link you came from (a place, such as a post on X or the Telegram bot — never a person), and the steps taken since; forgotten after 30 days. Only counts per tag may be sent to us, without any identifier. |
| Referrals (attribution) and sharing | `rxn.partner.*`, `rxn.share.*` | The partner link you came with (30 days, also set when you open a partner’s shared card), your own partner link, the delete keys of cards you shared, and your notes for the next card. |
| This visit and offline use | sessionStorage `rxn.app.*`, `rxn.window.*`; Cache Storage | Whether this tab is the Android app or a window you detached; the pages and fonts the site keeps so it opens without a connection. |
| Points | `rxn.me.*`, `rxn.points.*` | The address whose points you looked up. |
4Third parties
rxn.gg loads no third-party scripts on its regular pages. If you connect a wallet through WalletConnect, the WalletConnect software stores its own pairing data in your browser to keep the connection. Before a prediction-market sign-in when AGG requires it, a separate window may run Cloudflare Turnstile, a bot check, which can use its own cookies or similar technology under Cloudflare’s policy. Your wallet extension or app stores its own data under its own policy.
5Consent
Most of the cookies and storage above are strictly necessary for the service you ask for, or remember a choice you made, and need no consent: your language, the prediction session, the admin session, the RXN key, your wallet connection, practice, settings, layout and markets.
Three are not strictly necessary: `rxn_trader`, `rxn.ref.*` and `rxn.partner.*` credit campaigns and partners with the visits and trades they bring. None of them contains your name, your wallet address or an ID that identifies you, and none is used for advertising or to follow you across sites. You can remove them at any time by clearing the site’s data (see How to control them).
The visit count stores nothing in your browser; Global Privacy Control or Do Not Track turns it off.
6How to control them
You can delete cookies and site data at any time in your browser’s settings (usually under Privacy → Site data), or block them for rxn.gg. If you do, the site forgets your language, settings, practice and wallet connection, and you will need to turn the RXN key on again. Turning on Global Privacy Control or Do Not Track stops the visit count.
7Changes
If we add or change a cookie or a storage key, we update this page and its “Last updated” date first.
