Privacy Policy
Last updated: August 17, 2026
Alert System ("the Application") is a 24/7 site and metric monitoring tool. It periodically checks whether the sites and analytics data you configure are behaving as expected, and notifies you by Telegram and/or email when something looks wrong. This Privacy Policy explains what data the Application touches and how.
Depending on how an alert is configured, the Application accesses:
For "visibility" alerts, the Application loads the configured URL in a headless browser (Playwright) - the same as any visitor would - to check the HTTP status code, load time, and optionally the presence of specific text or an element on the page. No login credentials or non-public pages are accessed.
For metric-based alerts, the Application queries aggregate Google Analytics 4 export data stored in BigQuery (sessions, revenue, conversions and similar counts, never individual visitor records) via a Google service account, to compare a period against a threshold or previous period.
Data retrieved is used exclusively to:
We do not sell, share, or transfer the data described above to any third party. Notifications are delivered only to the Telegram chat and/or email address you configured for a given alert or project.
All communication with Google APIs and with the Application's own components uses HTTPS/TLS. Access to the Application's dashboard requires logging in with an authorized account. Google BigQuery access uses service-account-based authentication scoped to read-only analytics access - the Application never writes to or deletes analytics data.
Alert System's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
