Privacy Policy
Last updated: September 29, 2026
Crypto Tracking Widget ("the extension") shows cryptocurrency prices, charts and alerts while you browse. It needs no account and has no analytics, tracking or ads. This policy explains what data the extension handles and where it goes.
Data stored on your device
Your settings, watchlists, price alerts, chart drawings, tracked positions, portfolio, strategy bots and alert history are stored in your browser (chrome.storage.local). They never leave your device unless you turn on one of the features below. Uninstalling the extension deletes them. You can export or import them from the toolbar popup.
Data sent only when you use a feature
| Feature (off until you set it up) | What is sent | Sent to |
|---|---|---|
| Sync across devices (Pro) | Watchlists, settings and scanner rules | Your own Chrome account (chrome.storage.sync, operated by Google) |
| Alerts to Telegram / Discord / webhook | The text of your alerts, with the bot token or webhook URL you entered | Telegram, Discord or the https address you entered |
| Pro license | Your license key and an instance id | Lemon Squeezy, our payment and license provider |
| Wallet tracking | The public wallet addresses you add | Public blockchain nodes, to read their balances (read only) |
| AI chart read | Chart figures of the coin you ask about, with your own Anthropic API key | Anthropic |
| Economic calendar | Nothing about you (a plain request for the public calendar) | The public calendar feed |
Keys and tokens you enter (license key, Telegram bot token, Discord webhook, Anthropic API key) are stored in your browser and sent only to the service they belong to. The Anthropic API key is never included in backups or sync.
Market data
Prices, charts, order books and other market data are downloaded from public APIs (Binance, Bybit, OKX, Bitget, Gate, Coinbase, CoinGecko, CoinMarketCap, DexScreener, GeckoTerminal and similar). Token safety checks send the token's contract address to GoPlus or RugCheck, and network fees are read from public blockchain nodes (publicnode.com) and mempool.space. These requests contain no personal data.
Web pages you visit
The extension shows its widget on the pages you visit and looks for coin tickers such as $BTC to show a price tooltip. This happens on your device only: page content and your browsing history are not recorded or sent anywhere. The address of the current tab is used only to let you hide the widget on that site.
What we do not do
- We do not sell, rent or share your data.
- We do not collect personal information such as your name, email address or location.
- We do not use your data for advertising or to assess creditworthiness.
- Strategy bots only send you signals. They never connect to your exchange account or place orders.
Uninstall survey
If enabled, after you uninstall the extension your browser opens a short optional form. Its address contains only the extension version, the interface language and the number of days it was installed. No identifier is included.
Changes
If the extension starts handling data in a new way, this policy is updated first and the date above changes.
