The free edition works entirely inside your own WordPress installation. It does not require an external license server, has no time limit, and does not impose a usage quota.

Third Party Libraries
The plugin includes a local QR code JavaScript library based on Kazuhiko Arase’s QRCode Generator under the MIT License. License and copyright notices are included in THIRD-PARTY-LICENSES.txt and in the library files.
Installation
- Install the plugin ZIP through Plugins > Add Plugin > Upload Plugin.
- Activate the plugin.
- Open Settings > Permalinks and click Save Changes once.

- Save the QR code, test it with a smartphone, and then export it as PNG/SVG or use the print view.
FAQ
-
Can I change the destination URL later?
-
Yes. That is the purpose of the dynamic short URL. As long as the slug remains unchanged, the printed QR code does not need to be replaced.
-
Does the free edition require a license key?
-
No. The free edition can be used permanently without a license key.
-
How many QR codes can I create?
-
The WordPress.org edition does not limit the number of dynamic URL QR codes.
-
Are full IP addresses stored?
-
No. The simple scan counter does not store full IP addresses and does not use tracking cookies.
-
Will my data remain available after a later upgrade?
-
The free edition uses compatible tables for URL QR codes and scan data. A commercial edition can extend and reuse this data during a later upgrade.
-
Does the plugin load code from external servers?
-
No. The QR code library is bundled locally with the plugin. The free edition has no external updater and does not contact a license server.
