Privacy Policy
Jabr is designed to operate entirely offline. The on-device model processes all images locally — no image data, formula content, or personal information is ever transmitted to any server. All data remains solely on your device and is never shared with Beroea Tech or any third parties.
Jabr uses screen capture solely to let the user select a rectangular region of their screen containing a mathematical formula. The selection is initiated manually by the user via a keyboard shortcut or button press. No continuous or background recording occurs. The captured image is passed directly to an on-device machine learning model that converts the formula to LaTeX. The image is used only for this conversion and for display in the app's recent captures history.
