Privacy Policy

Compass Economic Calendar (Chrome extension) · Effective 28 July 2026 · Back to the calendar

Compass Economic Calendar does not collect, transmit, sell or share any personal data. There is no account, no analytics, no advertising and no tracking of any kind. The extension has no server: it reads one public file and stores everything else on your own device.

What the extension stores

All of this stays on your device, in Chrome's extension storage. None of it is transmitted to the developer.

Where	What	Why
`storage.local`	A cached copy of the public calendar feed, its HTTP ETag, the time of the last fetch, and the last fetch error if there was one	So the extension works offline and can skip re-downloading an unchanged feed
`storage.sync`	Your settings only: timezone and time format, theme, which event types the list and notifications show, how far ahead to look, whether notifications are on, and the warning offsets	So your settings persist, and follow you across devices where you are signed in to Chrome

Settings in storage.sync are synchronised by Chrome through your own Google account, under Google's privacy policy. They do not pass through any server operated by this project.

Network requests

The extension makes exactly one kind of request on its own:

A periodic GET of compasseconomiccalendar.github.io/calendar.json, roughly twice a day and whenever you press refresh. It sends no identifiers, cookies or query parameters — only the standard HTTP headers your browser attaches, plus an If-None-Match header carrying the previous file version.

That file is hosted on GitHub Pages. As with any website, GitHub receives the request and may log it (including your IP address) under GitHub's privacy statement. The developer has no access to those logs.

Separately, if you click an event's verification link or a notification, Chrome opens the relevant official page — federalreserve.gov, fred.stlouisfed.org, bea.gov, treasurydirect.gov or cmegroup.com. That is an ordinary visit to that site, governed by its own privacy policy. The extension does not open pages on its own.

What the extension does not do

No personal information is collected — no name, email, account or location
No analytics, telemetry, crash reporting or usage measurement
No advertising, ad networks or advertising identifiers
No cookies, fingerprinting or cross-site tracking
No reading, modifying or monitoring of the pages you browse
No content scripts — the extension never runs on any website
No remote code — all logic ships inside the extension, as Manifest V3 requires
No sale or transfer of data to third parties, because none is collected
No use of data for creditworthiness or lending decisions

Permissions and why each is needed

Permission	Purpose
`storage`	Save your settings and cache the calendar so the popup opens instantly and works offline
`alarms`	Refresh the feed on a schedule and fire advance warnings at the offsets you choose. Manifest V3 service workers shut down when idle, so alarms are the only way to run on time
`notifications`	Show those advance warnings. Notifications are generated on your device from the cached feed and are not sent from anywhere
Host access to `compasseconomiccalendar.github.io/*`	Download the calendar feed. This origin hosts nothing but this project's published files; the extension cannot read any other site

Your controls

Turn notifications off, or change their timing, on the extension's options page
Hide any event types you do not want to see or be warned about
Removing the extension deletes everything it stored in storage.local. Settings held in storage.sync are cleared by Chrome according to your Chrome sync settings

Children

This is a general-audience tool for tracking public economic release schedules. It is not directed at children and collects no data from anyone.
