Looking for a circle QR code generator that’s self-hosted or privacy-friendly

Hi folks — quick ask: is anyone using a circle QR code generator that can be either self-hosted or respects privacy (no third-party tracking)? I’ve been playing around with ME-QR, which works well in terms of design (supports circular styles), but it’s cloud-based.

If you’ve used anything locally or open source with similar visual features (circle shapes, branded styles), I’d really appreciate suggestions. Trying to use it for internal inventory tracking and ID tags, so aesthetics + privacy matter.
