Common questions
Does Line Eyes upload my photos?
No. Every filter runs in your browser using a Web Worker. There is no server to send images to. You can verify it in your browser's Network tab — no requests fire when you load or enhance.
Is enhancement medical advice?
No. Line Eyes is not a medical device. Enhancement can reveal real lines and can also exaggerate noise. Confirm important results with a digital test or your clinic.
Why is the app free?
It costs us nothing extra to host static files. There's no server, no accounts, no inference cost. Free for everyone, no API keys to plug in.
Does my cycle data sync between devices?
No. Cycle entries live in your browser's local storage on whichever device you saved them on. Nothing to sync means nothing to leak.
