Privacy Policy.
Effective date: July 16, 2026. We prioritize local execution so your data remains strictly yours.
1. Local-First Processing.
RealTimeZones is built as a local-first, static web application. Unlike traditional scheduling software, all time zone offsets, city selections, timeline scrubbing events, and calendar export links are calculated and rendered entirely on your local device.
We do not run search indexes or coordinate queries on remote database servers. Your searches are processed client-side against an optimized static city dictionary.
2. Local Storage Usage.
We utilize browser-based storage technologies (such as the standard localStorage API) to cache:
- Your active list of selected cities.
- Your preferred time format (12h vs 24h).
- Your active theme preference (System, Light, or Dark mode).
- Your timeline scrubbing state.
This data is stored purely within your local web browser. You can clear this data at any time by wiping your browser history/cache or by clicking the Reset Workspace button located within the navigation settings dropdown.
3. No Tracking & Cookies.
We prioritize local-first data integrity. We never sell, distribute, or monetize your team's configuration details to third-party data brokers. The public website uses Google Analytics to measure aggregate page visits; the packaged desktop app does not load analytics.
Purchases and license checks. Payments are handled by Dodo Payments, which collects the details needed to process your order; we do not receive your card details. When you activate or re-check a Pro license key, the desktop app sends the key and a generic device label (for example, "RealTimeZones desktop (Win32)") to Dodo's license service. No workspace, city, or calendar data is sent.
Update checks. The desktop app periodically requests a small public file from realtimezones.com to see whether a newer version exists. That request carries no key, workspace, or personal data, though our host sees the request's IP address like any web request. Updates are cryptographically signed and verified before they install.
4. External Contact Forms.
If you submit a query via our Contact Form, we only utilize your email address and message details to address your specific support request or feedback. We do not sell or add your email address to automated marketing lists.
5. Contact Information.
