KC Donate Box adds a lightweight donate/support panel after your posts:
This plugin can optionally generate QR images via an external API when the “QR mode” is set to “Auto”.
In that case, the plugin sends the wallet URI (e.g., “bitcoin:”, “ethereum:”) to the external service to get a QR image.
Service: GOQR – QR code API (api.qrserver.com)
– Purpose: Generating QR images for the configured wallet URIs.
– Data sent: Only the wallet URI (as the data parameter) and the requested QR size. No personal data is sent by the plugin.
– When: On front-end render (when the donate box is visible) and only for entries where QR Mode = “Auto”.
– Terms of Service: https://goqr.me/legal/tos-api.html
– Privacy Policy: https://goqr.me/privacy-safety-security/
– API docs: https://goqr.me/api/doc/create-qr-code/
If you prefer not to contact external services, set “QR mode” to “Upload” (use a locally uploaded QR image) or “None”.
