This page describes the current product and telemetry design in plain language. It is not a substitute for a final legal review; contact and jurisdiction details will be added before public launch.
Overview
ZMetrics is a Chrome extension that shows live crypto prices, market caps and 24h changes in a compact popup or floating window. It does not require an account.
Information we do not collect
ZMetrics does not collect browsing history, the URLs you visit, wallet addresses, passwords, authentication tokens, or the contents of the pages you view. Watchlist events do not include coin IDs, symbols or names.
Pseudonymous analytics
If analytics are enabled, the extension creates an anonymous installation ID once and stores it locally in chrome.storage.local. It also creates short-lived session IDs that expire after inactivity. These IDs are pseudonymous and are not created from your email, account or browsing activity.
Analytics events
Analytics may include installation and update events, extension opens, price-load success or error status, currency changes, watchlist change counts, and limited client error codes. Events use an event ID, installation ID, session ID, extension version and an allowlisted set of properties.
Opt-out
Analytics can be disabled from the extension settings. When disabled, no new analytics events are created and pending local analytics events are cleared.
Service providers
Analytics events are sent to the ZMetrics telemetry endpoint and stored in Supabase. Accepted events may also be forwarded server-side to Google Analytics 4 using the GA4 Measurement Protocol. The extension does not send events directly to Supabase or GA4, and service credentials are kept server-side.
Retention
The exact retention periods for telemetry data and operational logs are still being finalized. This section will be updated with the applicable periods before the public production launch.
Your settings
Tracked assets, their order and your currency preference are stored locally in your browser so the extension can remember them.
