About OneDollarTrack Gmail Open Tracking

A minimal, privacy-respecting Gmail open-tracking extension for personal use. OneDollarTrack Gmail Open Tracking tells you when an email you sent from Gmail has been opened. It is intentionally narrow: no click tracking, no analytics dashboard, no marketing features, no Outlook support. How it works: - Detects Gmail compose windows and attaches a lightweight send listener. - Just before Gmail sends a message, it registers a unique `message_id` with the OneDollarTrack backend and injects a hidden 1×1 tracking pixel into the outgoing HTML. - When the recipient opens the email, their mail client fetches the pixel, which our backend records as an open. - The extension periodically polls the backend (every ~1 minute via `chrome.alarms`) for status updates on messages you sent in the last 7 days. - A compact badge appears next to your sent thread in Gmail showing `Not opened` or `Opened N times` with first/last-open timestamps on hover. - The first time each message is opened, a local Chrome notification fires.
