Who runs Timezio
Timezio is built and operated by AffSquad, an independent studio that makes free, privacy-respecting web utilities. We're a small team that relies on these tools ourselves to coordinate across time zones, and we keep Timezio free by displaying ads. Questions, corrections, or feedback are always welcome at hello@timezio.com — see the Contact page for more ways to reach us.
