When is the start date and end date for the software maintenance subscription?

The protection period begins exactly on your software purchase date. For each purchase of a Navicat perpetual license or upgrade license, customers are automatically given a 1-year software maintenance plan.

Upon purchasing an extra 1 or 2 year(s) of coverage, your protection period commences precisely on the initial software purchase date and extends for an additional 1 or 2 year(s), depending on your selected plan.
