Guardia stores your address tags, categories, and notes locally in your browser using Chrome Storage. This data never leaves your device unless you explicitly export it.
If you enable Telegram monitoring, we store the monitored wallet addresses and your Telegram ID on our server solely to deliver real-time notifications.
We do not collect browsing history, page content, private keys, seed phrases, passwords, or any financial data. Guardia has no access to your funds — it only reads publicly available data displayed on block explorer pages.
Shield analysis runs entirely in your browser. Transaction data is analyzed locally using pattern matching — nothing is sent to external servers. No transaction history or page content leaves your device.
When you enable monitoring for an address, we store that address and your Telegram chat ID on our server to send notifications. You can disable monitoring or delete your account at any time — all associated server-side data is removed immediately.
You can export all your data (tags, categories, notes) as JSON at any time from the extension Settings. To delete all local data, uninstall the extension — all Chrome storage is cleared automatically. For server-side data (monitored addresses, Telegram link), use the logout option in Settings.
We do not sell, share, or transfer your data to any third parties. We use Google Fonts for typography on our website. The extension itself makes no third-party requests beyond the Guardia API (for monitoring features only).
Guardia requests minimal Chrome permissions:
storage — save your tags and preferences locally
activeTab — read the current block explorer page to tag addresses and detect threats
clipboardRead — clipboard protection against address swapping attacks
Content scripts only run on supported block explorer domains (Etherscan, BscScan, PolygonScan, and 16 others).
