External services
This plugin uses a third-party QR code API as a fallback when generating QR images:
Service: https://api.qrserver.com/ (GoQR / QR Server API)
Purpose:
Used to obtain a base PNG QR code image for the short URL (/q/<token>). The plugin then optionally composites this QR with a caption and branding.
Data sent:
Only the short URL is sent as the data parameter in the QR request, for example:
https://api.qrserver.com/v1/create-qr-code/?size=300x300&data=https%3A%2F%2Fexample.com%2Fq%2FAbC123%2F
No personal data or user-identifying information is transmitted.
Terms and Privacy:
- Terms: https://goqr.me/api/doc/create-qr-code/
- Privacy: https://goqr.me/privacy/
If the external API is unreachable, the plugin falls back to a plain QR URL and continues to function.
