Privacy Policy

Last updated: September 2026

Tzplan is a product of Agen2ic, LLC, a Colorado limited liability company.

What data does Tzplan collect?

None. Tzplan runs entirely in your browser. There is no server, no database, no analytics service, and no backend of any kind. The time zone data is drawn from your browser's built-in Intl API — the same database every web application uses. Participant names, cities, working hours, and the overlap grid exist only in memory while the page is open. Nothing is saved, uploaded, transmitted, or stored after you close the tab.

Cookies

Tzplan does not set any cookies. It has no session management, no authentication, and no tracking.

Third-party services

This site loads font files from Google Fonts (Sora, DM Sans, JetBrains Mono) and nothing else. Google Fonts requests include your IP address, which is standard for any web font loading. No analytics, advertising, or social-media trackers are present on any page.

Data sharing

Because no data is collected, no data is shared, sold, or transferred to any third party.

Changes to this policy

If this policy changes, the updated version will be published at this URL with a new date. Because the tool itself has no server, the privacy implications cannot change materially — the tool's architecture is the guarantee.

Contact

For questions about privacy or the tool itself, email tzplan-p1@agen2ic.ai. agen2ic.ai accepts mail at any local part, so the address reaches a human and identifies which product your query concerns.
