Privacy Policy

Antidrain is built and run by Zun, who is responsible for the processing described here. You can reach Zun as shown under "Contact" at the end of this page.

Your private keys and seed phrases never leave your device. Every transaction is signed in your browser, and only the signed transaction and public wallet addresses are sent to the blockchain networks.

The site saves the following in your browser's local storage, so your work is still there when you come back. None of it is sent to Antidrain.

• Sponsor wallets. The EVM and Solana sponsor wallets you generate or restore on the Generate tab, with their private keys and the seed phrase, and the wallets you replaced there, so a funded wallet is never lost.
• Rescue forms. Everything you type into a rescue form, including the compromised wallet's private key, the safe address and the claim data, for each wallet tab and rescue type.
• Settings. Your light or dark theme, the dashboard tab and rescue type you had open, the RPC URL you typed on the Advanced page, and which help hints you have closed.
• Referral. The referrer's wallet address, if you opened the site through a referral link. It is added to your EVM rescues (see the Terms & Conditions).
• Not encrypted. These values, private keys included, are stored as plain text. Anyone or any program with access to this browser profile can read them.

Each request below is made only to provide what you asked the site to do, except Google Analytics, which helps us understand how the site is used. Like any web request, each one also reaches its receiver with your IP address and your browser's usual request details.

• EVM networks. To read balances, estimate fees and send transactions, the site calls each network's public RPC endpoints (run by providers such as PublicNode, Pocket Network, Tenderly, thirdweb and the networks themselves), or the custom RPC URL you enter. These calls carry wallet addresses, transaction data and signed transactions.
• Solana. Solana calls go through Antidrain's own RPC proxy at api.antidrain.dev, which passes them on to a Solana RPC provider. They carry wallet addresses, transactions to simulate and signed transactions, never a key, plus a short-lived session token that lets the proxy answer only this site.
• Hosting. The site is served by Vercel, which receives the usual request details when your browser loads a page.
• Google Analytics. The home, docs, reviews and refer pages and the not-found page load Google Analytics, which counts visits and reads details such as your browser, device and approximate location, the page that sent you and any campaign tags (utm_) in the link you followed. Those tags are then removed from the address bar. The dashboard and Advanced pages, where keys are handled, load no analytics at all.
• YouTube. The video on the docs page is loaded from youtube.com only after you press Play.
• WalletConnect (Reown). On the Advanced page, Reown's wallet connector is loaded only when you choose to connect your own wallet. Its analytics are turned off.
• Links. Links to X and the Chrome Web Store only open those sites; nothing from them is loaded on Antidrain's pages.

Antidrain's own code sets no cookies. Google Analytics sets its own cookies on the pages listed above, and YouTube may set cookies once you play the video.

• Google's opt-out add-on stops Google Analytics in your browser. Blocking third-party cookies or using a content blocker works too; the site works the same without them.

• In your browser. Until you remove it: clearing this site's data in your browser deletes all of it. Download or copy your sponsor wallet's key first if it still holds funds, or they are lost.
• Google Analytics. Kept by Google for the retention period set for the site's analytics property, at most 14 months for detailed visit data.
• Service providers. RPC providers, Vercel and Google keep request records under their own policies.
• On the blockchain. Permanently (see below).

Vercel, Google and the RPC providers run servers in several countries, including the United States, so the request details above may be processed outside your country.

A rescue is a blockchain transaction. Its addresses, amounts, the fee and any referral payout are recorded publicly and permanently on that network. Antidrain cannot change or remove them.

A share link holds the form values you choose to share (such as the safe address, contract, claim data, NFT list or Solana transaction, and the referrer) after the # in the link, a part browsers do not send to servers. It never holds a private key. Anyone you send the link to can read those values.

Depending on where you live, you may have the right to ask what personal data is held about you, to have it corrected or deleted, to object to its use, to withdraw consent, and to complain to your data protection authority.

Antidrain holds no account or profile about you: what it keeps is in your own browser, which you can clear at any time, and Google Analytics can be stopped as described under "Cookies". For any other request, contact Zun as shown below.

Antidrain is not meant for anyone under 18, and it does not knowingly process data about children.

The site is served over HTTPS. The pages that handle keys load no analytics, and the Advanced page loads WalletConnect only when you choose to connect a wallet. Your keys are as safe as the device and browser you use, so use the dashboard on a device you trust and keep your browser up to date.

Antidrain has no accounts and no database of users, does not sell or share data, and uses no tracking or error-reporting service besides the Google Analytics described above.

This page is updated when the site changes what it stores or sends; the date at the top shows the last change.
