External services
This plugin does not connect to any third-party services.
Privacy
This plugin does not collect or share any personal data.
It does not send any information to external servers.
All invoice and tax data is stored locally within your WordPress database.
Developer Notes
This plugin follows WordPress coding standards and enqueues all CSS/JS properly.
In certain cases, inline <style> blocks are used inside PDF template files only.
Reason: These templates are rendered by the PDF generator (dompdf/dompdf). WordPress functions like wp_enqueue_style() cannot be applied in this context because the output is not a browser page, but a static PDF.
The inline CSS is always loaded from local files bundled with the plugin and does not include any dynamic code or external requests. This approach is required for correct PDF rendering.
All front-end and admin scripts/styles outside of PDF templates are enqueued using wp_enqueue_style() and wp_enqueue_script().
