Issue product warranty certificates, track serial numbers and coverage dates, and print A4 warranty documents with local QR codes.

== Description ==

**AwoWarranty 2.2.0** is a self-contained corporate B2B studio for WordPress (`WP Admin -> AwoWarranty`).

= What AwoWarranty Does =

AwoWarranty enables manufacturers, distributors, and technical installers to issue serial-numbered warranty certificates, track warranty expiration dates, and print official A4 warranty certificates with offline QR codes.

= How to Configure and Use AwoWarranty =

1. **Open the Studio:** After activating the plugin, click **AwoWarranty** in the WordPress admin sidebar (requires `manage_options` capability).
2. **Configure Company Settings:** Enter your manufacturer/distributor company details, support contact information, and standard warranty coverage terms in the Company Settings panel.
3. **Create or Select a Record:** Click **+ New Warranty Certificate** and enter the product name, model code, serial/batch number, buyer name, invoice reference, start date, and warranty duration (e.g., 24 months).
4. **Calculate, Filter, and Manage Status:** Monitor active vs. expired warranties in the registry table and filter certificates by serial number or customer name.
5. **Save, Print A4 PDF, or Export:** Click **Save** to store certificates in WordPress, click **Print A4 Warranty Certificate** to output the official certificate with local SVG QR code, or export to CSV / JSON.

= Key Features =

* **Live Two-Column Studio & Instant A4 Print Preview:** Edit your records on the left and preview the formatted A4 corporate document on the right (`@media print` ready).
* **100% Local WordPress Database Storage:** Stores workspace records safely inside `wp_options` (`awowarranty_workspace_v1`) via Nonce-verified and capability-checked WordPress AJAX (`manage_options`).
* **CSV & Portable JSON Export / Import:** Export records to Excel-compatible CSV or portable JSON backup files at any time.
* **Adaptive Day / Night UI:** Supports automatic system theme detection as well as manual Light and Dark modes.

= External Services =

* **100% Local Default Operation:** By default in Free mode, AwoWarranty runs 100% locally inside your WordPress site and makes **zero external HTTP requests**.
* **Optional AWO-Guard / Polar.sh PRO License Verification (`https://awosign.awoscan.com`):** Only when a site administrator explicitly enters an optional PRO license key (`AWO-WARR-...` or `AWO-SUITE-...`) and clicks Activate, the plugin sends an HTTPS POST request to `https://awosign.awoscan.com/api/license/activate` containing the license key, site domain, and company name to verify the license and issue a signed domain lease token.
  * Service Provider: AwoScan / AWO Cloud Portal (`https://awosign.awoscan.com`) & Polar Software, Inc. (`https://polar.sh`)
  * Terms & Privacy Policy: `https://awoscan.com/privacy` and `https://polar.sh/legal/privacy`

= Privacy and Data Storage =

AwoWarranty stores all records, company settings, and uploaded logos/stamps locally inside your own WordPress database (`wp_options` under `awowarranty_workspace_v1`). No business records or customer data are sent to external servers. All stored options are automatically removed when the plugin is uninstalled (`uninstall.php`).

= Source Code =

All PHP, JavaScript, and CSS files in this plugin are distributed in human-readable, unminified source form directly inside the plugin directory (no external build tool or compiler is required):

* awowarranty.php - WordPress admin studio, serial registry, local QR renderer, and A4 warranty certificate layout.

== Installation ==

1. Upload the `awowarranty` folder to `/wp-content/plugins/` or upload the plugin ZIP file via **Plugins -> Add New -> Upload Plugin** in WordPress.
2. Activate **AwoWarranty** through the **Plugins** menu in WordPress.
3. Click **AwoWarranty** in the WordPress admin sidebar (`manage_options` capability required).
4. Configure your company header, add your first record, click **Save**, and use **Print A4 / PDF** to generate your document.

== Frequently Asked Questions ==

= Does AwoWarranty require an external account or cloud subscription to work? =

No. AwoWarranty runs locally inside WordPress out of the box with no external account required.

= Where is my data stored? =

All data is stored in your own WordPress database inside the `wp_options` table (`awowarranty_workspace_v1`) and can be exported to JSON or CSV at any time.

= Can I print A4 documents or save them as PDF? =

Yes. Click the Print A4 button inside the studio to open your browser's native print dialog, where you can print directly to an A4 printer or choose "Save as PDF".
