Frequently asked questions

Everything you need to know about LumiTag.

Does LumiTag need internet?

Only for the first launch — it downloads the AI engine (0.5–3 GB depending on GPU) and your selected models (1–8 GB). Total: 1.5–10 GB depending on configuration. After that, everything works 100% offline.

What photo formats are supported?

JPG, PNG, HEIC/HEIF, and TIFF.

Will it work without a GPU?

Yes! CPU mode works on any Windows 10/11 PC. GPU (NVIDIA 4 GB+ VRAM) makes it 3–10× faster.

Where are tags saved?

Directly in photo files as IPTC Keywords and XMP Subject. No database, no lock-in.

Can I use it with Synology Photos?

Yes! Tags are written as IPTC keywords which Synology Photos indexes automatically.

What about Windows SmartScreen warning?

LumiTag is not yet code-signed. Click "More info" → "Run anyway". This is safe — the app is fully offline and open for inspection.

How do I get a refund?

Purchases are handled by Paddle.com. Contact them within 14 days for a full refund.
