Privacy

otcproxima.app and the otcproxima Wallet browser extension. Unofficial community project, not affiliated with the Proxima developers. Last updated 6 November 2026.

What stays on your device

• In the wallet extension: your recovery phrase and private keys, encrypted with your password, plus your settings, the sites you connected, the payout addresses you approved and receipts of your trades. Chrome stores these in the extension's own storage.
• In your browser, for the website: which wallet you connected, that you accepted the risk notice, your own offers and pending trades, and any custom network address you entered. This is browser storage, not cookies, and it is not sent to us. Clearing your site data removes it.

What our server receives and keeps

When you use the market, your browser or wallet sends these to our server, and we keep them as the record of the market:

• your public Proxima holder ID and public EVM address;
• your offers and trades: amounts, prices, networks, transaction IDs and their status;
• your signatures on those requests, which prove you made them (signatures cannot be used to spend your funds);
• the last time your wallet was active, which the market shows as "online" or "last active";
• any transaction ID reported for a trade.

We use this to run the order book, match and settle trades, show track records such as completed trades and no-shows, and stop abuse. Most of it is public: anyone can see offers, trades, track records and oracle signatures through this site and its API. Backups of the database are kept for 14 days.

Server logs. Like most websites, our web server logs each request: IP address, time, page or API path and browser type. We use these to keep the service running and to investigate abuse. Logs are deleted automatically, within 90 days at most. IP addresses are also held briefly in memory to limit excessive requests. We do not use them to identify you or link them to your trades.

Who else sees data

• Blockchains. Ethereum, Arbitrum and Proxima are public. Your addresses and transactions on them are visible to everyone, permanently. Neither we nor anyone else can delete them.
• Network providers your wallet and browser connect to directly. To read balances and send transactions, they contact public services, which can see your IP address and the addresses you ask about. They are not run by us and have their own policies:
  • Arbitrum and Ethereum: arb1.arbitrum.io, publicnode.com, drpc.org, blastapi.io (and their test networks, if you turn those on);
  • Proxima public access nodes: 65.21.170.230, 79.137.70.25, 51.254.47.76. These connect over plain HTTP, so this traffic is not encrypted. It carries only public blockchain data and signed transactions, never your keys.
  You can set your own network addresses in the wallet's settings.
• Service providers who help us run the service: our server host; Cloudflare, which answers DNS lookups for this domain; Let's Encrypt, which issues our security certificate; Alchemy, which our server uses to read the blockchains (it sees public addresses, not your IP); UptimeRobot, which checks the site is up; and Discord, where our operators receive service alerts that can include trade IDs, which are public.

We do not share data with anyone else, unless the law requires it.

The wallet extension's permissions

The extension runs on otcproxima.app only and reads no other sites or your browsing history. It connects to the network services listed above, and to a custom address only if you add one and approve it. It keeps its code inside the extension and loads none remotely.

Your choices

• You can export your keys, uninstall the wallet or clear your browser data at any time. Uninstalling deletes the wallet from that browser, so back up your recovery phrase first: we cannot recover it.
• You can ask us what we hold about an address, or ask us to correct or delete it, using the support channel on the Help page. We may need to keep records of trades to settle them, prevent abuse or meet legal duties, and we cannot change anything on a blockchain.

Changes

If this page changes, we will update the date at the top. If a change affects what we collect, we will say so on the site.
