LightYet does not require an account and contains no advertising or third-party analytics SDKs. Non-AI records are stored on your device. If you enable iCloud sync, supported data is stored in your private iCloud container. AI features are optional. Only after you agree and request an AI feature, selected information needed for that request may be sent to LightYet's AI processing service. Depending on the feature, this may include a meal photo or description, your question, and relevant profile, weight, body-fat, or calorie summaries. Progress photos are not included in AI body trend reviews. AI estimates can be inaccurate and should be reviewed before saving. Nutrition targets are planning estimates, not medical prescriptions. LightYet is not a medical device and does not replace professional medical advice.
