GPL-licensed code with separately managed service entitlements.

Plugin code and artwork

The Notice27 plugin header and readme declare GPL-2.0-or-later. The European Commission notice artwork is official source material and is not claimed as Kastovia-owned artwork.

Paid entitlements

Solo (€29), Business (€69) and Agency (€149) purchases issue the selected service-managed licence and protected 2.1.0 download after server-side payment verification. The customer account supports activation visibility, self-service deactivation or transfer within safeguards, download access, and key recovery by rotation.

A seven-day trial is available before purchase subject to domain/site identity and abuse limits. Every paid plan uses the same protected delivery and customer-account workflow; plan differences are site capacity, agency use and support priority.

Updates and continuity

Update metadata is signed and packages are checksum-verified. A service entitlement controls access to future protected releases; it does not alter the GPL licence or remotely deactivate an installed copy.
