Privacy policy

What the extension handles

• Your Helius API key or keys. You paste these in Settings. They are saved in your browser and sent only to Helius, as part of each data request. The developer never receives them.
• Wallet and token addresses. The addresses you type or paste, and the ones found while scanning a token's traders or holders. These are public blockchain addresses. They are sent only to the data services below that look them up, never to the developer's server.
• Analysis results. Trade histories pulled from the blockchain, scores, filters, token names and prices, saved Holders checks, your History list and your Saved wallets. Kept in your browser.
• Your invite code and sign-in token. See Invite codes.
• Your settings. Analysis options and display choices. Kept in your browser.

The extension does not ask for or read your name, email address, browsing history, passwords, private keys or seed phrases. It never connects to or signs with a crypto wallet and cannot move funds.

Invite codes

Copytrade Wallet Analysis is invite only. When you enter your code, the scoring server checks it and gives your browser a random sign-in token, which is saved in your browser and sent with each scoring request so the server knows the code is valid. For each code the server keeps:

• the code, its status (active, turned off or expired) and any expiry date;
• for each browser it was activated on: the browser type and operating system (for example "Chrome · Windows", worked out from the browser's user agent), the activation date, when it was last used and about how many scoring requests it made;
• a one-way fingerprint (hash) of each sign-in token, not the token itself;
• invite codes given to you to share, and whether each has been used and when (not who used it);
• a note the developer may add when handing out a code, such as a Discord name or support ticket number.

This record is used only to check codes, limit each code to its allowed browsers, hand out invites and answer support requests. It does not include your IP address, location, email or any wallet address.

Services it contacts

The developer's server runs on Cloudflare Workers. Like any website, Cloudflare receives your IP address when a request arrives; it is used briefly to limit how many requests one visitor can make and is not stored by the developer (see Cloudflare's privacy policy). The third-party data services handle requests under their own privacy policies; the developer has no access to what you send them.

GMGN pages

On gmgn.ai the extension reads the address of the page you are on and the token links on it, so it can show a score badge and labels for wallets you analyzed, and so Top traders can use the token page you have open. It does not click, type, submit or change anything on GMGN, and nothing from the page is sent to the developer. Turn it off in Settings → Analysis → Show Wallet Score on GMGN pages.

Local Filter Finder files

If you open a saved Filter Finder report file from your own computer (a file whose name contains "Filter Finder"), the extension can read it to fill in its results. It does not read any other files, and the file's contents stay in your browser.

The web app

The web app on this site runs the same analysis in your browser tab and works the same way: your Helius key, invite sign-in token, wallets and results are saved in this site's storage in your browser and sent only to the services above. This website has no analytics and no tracking cookies. Clearing this site's data in your browser deletes everything the web app saved.

Syncing with the extension: if the extension is installed in the same Chrome browser, your Saved wallets and folders are kept the same in both. The copy goes directly between this site's page and the extension inside your browser, using Chrome's extension messaging (only this website can talk to the extension this way). It is not sent to the developer or anyone else.

Storage, retention and deletion

• In your browser: keys, settings, trade histories, scores, History and Saved wallets are kept in your browser's extension storage on your device and are not sent to the developer. Trades older than 31 days are removed automatically. History → Clear history and Settings → Storage remove saved data. Removing the extension deletes everything it saved.
• On the developer's server: only the invite code record described above. It is kept while your code exists. You can ask for your code and its record to be deleted at any time by opening a ticket in our Discord; deleting it signs out every browser using it.

Permissions

• Side panel: shows the extension next to the page you are browsing.
• Storage and unlimited storage: keep your settings, keys and saved trade history on your device so reopening a wallet is free.
• Access to Helius, GeckoTerminal, DexScreener and Binance.US: the data services listed above.
• Access to gmgn.ai: the page labels, and reading which wallet or token page you have open.
• Local files named "Filter Finder": only if you open such a file, to read its results.
• Messages from this website (externally connectable): lets the web app on this site, and only this site, keep your Saved wallets and folders the same as the extension's. This is not a permission prompt and gives the site no other access.

Limited use

The use of information received by the Copytrade Wallet Score extension adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. Data is used only to provide the extension's wallet analysis and invite system. It is never sold, never transferred to third parties except the services above as needed for that purpose, never used for advertising or personalized ads, never used to determine creditworthiness or for lending, and never read by humans except to answer your own support request or where required by law.

Security

All connections use HTTPS. Sign-in tokens are random and stored on the server only as one-way hashes. Each invite code is limited to its allowed number of browsers, and repeated wrong codes are rate-limited.

Children

Copytrade Wallet Analysis is meant for adults and is not directed to children under 13. It does not knowingly collect information from children.

Other terms

• The extension is an analysis tool. Its scores and filters are estimates from past trades, not financial advice.
• It is not affiliated with GMGN, Helius, GeckoTerminal, DexScreener or Binance.US.
• If this policy changes, the new version will be posted here with a new effective date.

For questions about this policy or to delete your invite code record, join our Discord server and open a ticket, or use the Support tab on the extension's Chrome Web Store page.
