Camera stays purposeful
Webcam mode uses camera access for gaze estimation during the active test flow.
Privacy
Designed for children, supervised by adults.
Lexora handles reading and gaze information with a narrow purpose: support supervised dyslexia risk screening and learning follow-up. This page explains what the product uses, what it avoids, and why.
Last updated: May 2026
No video-first design
The product is built around gaze coordinates and fixation features, not stored video recordings.
Guardian-led sessions
Children are supervised by guardians, parents, or teachers. Child accounts are not independent login identities.
Sensitive access is limited
Where guardian or claim information is needed, it should be collected only for a clear purpose.
What data means here
Gaze data is not a face recording.
During screening, Lexora cares about where gaze lands on the screen and how long it stays there. That information is used to produce a risk signal and visual context for the supervising adult.
Gaze samples
Screen x/y coordinates and timestamps captured during reading.
Screen metadata
Display size and normalized coordinates used to interpret gaze correctly.
Prediction output
Risk level, probability, confidence, and derived fixation context.
Guardian context
Profile and supervision information needed to run and review child sessions.
Camera and webcam mode
Webcam mode requests camera permission only for the active screening flow. The camera feed is used to estimate gaze through browser-based face and iris landmarks. Lexora does not need to store video recordings to perform this screening experience.
Tobii helper service
Tobii mode uses a local helper service to stream gaze data from supported hardware to the web app. This enables precise tracking while keeping the device connection local to the screening machine.
Children and guardians
Lexora is designed for guardian-supervised use. Parents and teachers manage child profiles, test initiation, retakes, and report review. Children should not be asked to manage privacy decisions alone.
Research and diagnosis
Lexora is a screening and research tool. Results are not a clinical diagnosis. If a result indicates risk, it should be discussed with qualified professionals for proper assessment and support planning.
