FAQ
Is my data uploaded to a server?
No. Whenever possible, processing happens locally in your browser and we do not store your inputs or results on our servers. (Network requests may still occur for page loads and ads.)
Is DST handled automatically?
Yes. It uses your browser’s IANA time zone data (Intl API), including DST where applicable.
Can I add a city/time zone that is not listed?
Yes. You can type an IANA time zone (e.g., Asia/Seoul) and add it directly.
