For the Nhắc Âm Lịch browser extension. Last updated: 9 September 2026.
By installing and using the Nhắc Âm Lịch extension, you agree to the terms below. If you do not agree, please do not install it, or uninstall it.
The extension is provided free of charge, "as is", without warranty of any kind. The developer makes no guarantee that it will run without errors or interruption, or that it will be compatible with every browser version.
The extension computes lunar dates using an astronomical algorithm anchored to UTC+7. The results have been checked against widely used calendar reference points and match. However, different printed calendars sometimes differ by one day in certain months, because of differing rounding conventions or reference time zones.
For occasions that matter — death anniversaries, weddings, family rites — you should check against your family's calendar or whichever source you normally trust. This extension is a reminder tool, not an authoritative source on calendrical rules.
The developer is not liable for any damage arising from use of the extension, including but not limited to: notifications that fail to appear, appear at the wrong time, dates computed incorrectly, calendar events created incorrectly or deleted, or a missed occasion.
You are responsible for verifying any date you consider important.
The sync feature depends on the Google Calendar API. The developer does not control that service and is not responsible if Google changes, limits or discontinues it, causing sync to stop working. In-browser notifications continue to work independently, with no need for Google.
Data handling is described in the Privacy Policy, which forms an integral part of these terms.
These terms may be updated. Revised versions will be published at this address with an updated date.
