What It Is

TimeHopper is a Chrome extension built for distributed teams. Its core goal is to bring multi-time-zone world clocks and your personal Google Calendar into a single browser popup, helping users check schedules, convert time zones, and arrange meetings without switching tabs. It is more of a lightweight personal productivity tool than a full enterprise scheduling or meeting management platform.

Core Features and Integrations

The product includes a world clock for checking the local time of colleagues in places such as London, New York, and Tokyo, and it supports custom labels so users can organize clocks by team rather than by city. Google Calendar Sync is its main integration: after connecting an account, users can view the day’s events in the popup and join video meetings with one click. Smart Alerts send desktop notifications for upcoming meetings. The website also provides a time zone converter and a world time zone map that can be used without registration.

Pricing and Ease of Use

The page repeatedly states “Add to Chrome - Free” and “It's Free,” indicating that the Chrome extension is currently free to use. However, it does not disclose any paid, team, or enterprise plans. As a browser extension, it has a low barrier to entry and is well suited for remote workers who already rely on Google Calendar and want to get started quickly.

Data Security and Permissions

TimeHopper explains its data usage fairly clearly: it requests Google Calendar’s calendar.readonly permission to display events and provide local reminders, and userinfo.email to identify the calendar account. It states that it does not sell data, browsing history, or event details, and that it does not store calendar events on its servers; processing takes place on the local device. This is a plus for privacy-conscious individual users. However, the page does not disclose compliance certifications such as SOC 2, ISO 27001, or GDPR, nor does it provide an enterprise-grade security white paper.

Pros, Cons, and Who It’s For

Its strengths are that it is free, lightweight, focused on cross-time-zone meeting scenarios, and has a straightforward privacy policy. Its limitations are that it only clearly supports Google Calendar, with no visible integrations for Outlook, Slack, Microsoft Teams, Feishu, or similar tools. There is also no information about team management, permission controls, an admin console, SLA, or customer support systems. It is suitable for members of small international teams, freelancers, and remote workers as a personal time zone and schedule assistant. If an organization needs centralized permissions, auditing, compliant procurement, and multi-system integrations, alternatives such as Calendly, World Time Buddy, Outlook/Google Workspace, or Feishu Calendar in China may be more appropriate.

Access from China

The text does not state whether the website or Chrome extension is accessible from mainland China. In addition, Google Calendar and Chrome Web Store may face access restrictions in domestic network environments, so actual usability may depend on network conditions.
