Privacy

Stored on your device

• GMGN API key
• Wallet addresses you blacklist
• Display settings and widget position
• GMGN response cache
• Account id, account secret, install id, public account code, session id, a license cache, and a referral code from an install link until it is applied

Uninstalling the extension deletes this data.

Sent to us

Host: license.bigbrother.watch. For license checks and payment we receive account id, account secret, install id, session id, the chosen plan, a redeem code if you apply one, and a referral code if one came with the install link or you apply one. We store a hash of the secret, the public account code, device slots, invoices, and paid-until. We do not receive your GMGN API key, blacklist, or page contents.

An install link on bigbrother.watch stores the referral code in a cookie named bb_ref for 30 days. The extension reads only that cookie, sends the code to the license server when the account is created, and then deletes the cookie. It does not read other cookies or browsing history.

Sent to other hosts

openapi.gmgn.ai — token holder/trader data, using the API key you paste. Request goes to GMGN, not to us.

api.dexscreener.com — a pool or pair address from the page, to resolve the token mint. Request goes to Dexscreener, not to us.

NOWPayments — Pay creates an invoice on our license server, then opens NOWPayments checkout on their domain. The extension does not call NOWPayments. We do not handle your wallet or crypto.

Content scripts run on GMGN, Axiom, FOMO, Pump.fun Terminal, Dexscreener, and on bigbrother.watch. The trading pages are not sent to us. On bigbrother.watch the script reads only the referral code in the link.

By click, in a new tab: Telegram Updates and Support, X, blockchain explorers, Arkham, GMGN wallet pages, and NOWPayments checkout. Those visits are not sent to us.

What we do not collect

We do not collect email. We do not sell data.

Limited Use

We do not sell user data, use it for advertising, or transfer it except to the hosts listed above that are required to run the product.
