Saved on your device

TimeMingle stores your chosen cities, their order, reference city, working hours, time format and theme in your browser's local storage. There is no TimeMingle account or server-side profile. Clear this site's browser data to remove those preferences.

When you share

A shared link contains the places, selected moment and working hours in the link's fragment (the part after #). The fragment is not sent in an HTTP request to the hosting server. Anyone you send that link to can read the comparison. Your browser history and clipboard can retain it.

Hosting and third parties

The website is hosted with ChatGPT Sites. The hosting provider may process technical request information such as your IP address and browser information to serve and protect the site. See OpenAI's privacy policy. Fonts are hosted with the site. This version adds no advertising trackers or analytics scripts.

Calendar and Slack

Scheduling messages and email addresses are parsed in your browser and are not saved by TimeMingle. They stay in this tab until you close or reload it. Review in Google Calendar passes the draft title, guests and times to Google in a link, only when you choose it. Google Calendar handles saving and sending invitations. A downloaded .ics file stays on your device until you import or share it. This site does not read your calendar, check availability, or send messages to Slack. Copying only puts text on your clipboard.

Time-zone accuracy

TimeMingle uses published IANA rules for dates from 2020 to 2035. Future rules can change. Check your calendar invitation's time zone when scheduling important events.
