Your email address is stored securely on our backend infrastructure (Upstash). It is never sold, rented, or shared with any third party outside of what is described in this policy.

1.2 Payment & License Status

We store your payment status and license information (e.g. whether you hold an active license) in association with your email address. This is used solely to determine whether you are authorized to use the extension.
