Privacy-first · On-device AI
Enhance photos.
Not your privacy.

Everything you need, nothing you don't
A focused set of tools built around one idea: your photos stay yours.
🗂️
Batch Upscale
Queue several photos and let Lumixa work through them one after another — no repeated setup per image.
🔍
Before / After Compare
A synchronized slider with fullscreen, pinch and double-tap zoom, so you can see exactly what changed — and what didn't.
📦
On-device AI models
Download once, then run fully offline. Manage, update or remove models any time — more tools are on the way.
🎨
Made to feel like yours
A calm dark theme by default, accent colors, reduced motion and haptics — personalization without the clutter.
📤
Save & share instantly
Save to Photos or Files, or share straight to WhatsApp, Instagram, Facebook and anywhere else installed on your phone.

Drag each slider. These illustrate the kind of clarity Lumixa adds — softness and noise reduced, edges and texture brought back.

Four steps. All on your phone.
01
Select a photo
Pick an image from your library. Lumixa shows its dimensions, format and size before doing anything.
02
Choose your output
Basic mode: pick 2×, HD, FHD or 4K. Advanced mode: choose the model, scale, format and quality yourself.
03
Enhance, on-device
Inference runs locally in memory-safe tiles, with live progress and a cancel button — never a server round-trip.
04
Compare & save
Slide between original and enhanced, then save to Photos, save to Files, or share directly.
Privacy, by architecture
“Processed on this device.
Your photo is not uploaded.”
This isn't a policy promise — it's how Lumixa is built. Every enhancement runs through an on-device model. There is no server that ever receives your image.

Questions, answered
Do my photos ever get uploaded anywhere?
No. Enhancement runs entirely on your device using a local AI model. Firebase is used only for sign-in, subscription status and privacy-safe usage counts — never for image content.
Does Lumixa work without internet?
Yes, once you've signed in and downloaded a model. Selecting, enhancing, comparing and saving photos all work offline. A connection is only needed for sign-in, model downloads and entitlement refresh.
What's the difference between Fast and Quality 4×?
Fast 4× is optimized for speed on more devices. Quality 4× (Lumixa Pro) spends more compute per photo for sharper, more detailed results.
Can I cancel my subscription anytime?
Yes. Lumixa Pro is billed monthly through Google Play, and you can cancel or manage it directly from the Play Store at any time.
