## What is Lumen?

Lumen is a privacy-first smart camera. Shoot, watermark, scan, and lightly edit — all on your device. We don’t upload your media to our servers.

Capture
• Photos and video with timer, grid, and level
• Live Photos to keep motion around the shutter
• Burst and preview-before-save for quick picks

Watermarks you can preview
• Stamp time, place, or custom text
• Live preview in the viewfinder
• Great for work check-ins and everyday memories

Scan & documents
• QR codes and barcodes — copy or open links
• Document scan with text extraction (OCR)
• Scan history stays on this phone

Smart modes & Pro
• Night multi-frame fusion for low light
• Portrait background blur
• Pro: exposure, ISO, white balance, AE/AF lock

Light edit & share
• Filters plus brightness, contrast, saturation
• Postcard, stamp, and grid templates
• Edit and share in a few taps

Local-first privacy
Lumen processes photos and videos on your device. Location is used only when you enable Save location or a location watermark. We do not upload your media to our servers.

For daily moments, field notes, or quick document text — Lumen keeps shooting simple and private.
