Clocking in requires the Opervia Tracker extension for Google Chrome. This section describes exactly what that extension does and does not do.

What it collects: Once per minute, while you are both signed in and clocked in, the extension reports a single number from 0 to 100 — the percentage of that minute during which your computer was in use, together with the site timings described below.
How activity is measured: Via your operating system's idle state, which reports only whether input occurred. The extension does not record keystrokes, mouse positions, screen contents, or screenshots.
Time per website: While you are clocked in, the extension records the domain name of the browser tab you are working in (for example github.com) and how many seconds you spend there. This is stored as a daily total per domain.
What is never recorded: Page addresses beyond the domain, page titles, form contents, and search terms. A search, a bank page, or a private document contributes a domain name and a duration — never the query you typed, the page you opened, or what was on it. The daily totals are aggregates, so they cannot be used to reconstruct the order in which you visited sites, or when.
When it is inactive: No activity is recorded while you are clocked out, on a break, or signed out. Clocking out stops collection entirely.
Retention and access: Activity scores are aggregated into daily averages, and site time into daily per-domain totals, both visible to your organization's administrators. Individual per-minute samples are not shown to anyone.
No sale or transfer: Activity data is never sold, shared with third parties, or used for advertising, and is not used for any purpose unrelated to your organization's attendance records.
Removing the extension stops all collection immediately, but will also prevent you from clocking in.
