How we use AI with your data

Some LeanerTogether features are powered by artificial intelligence so your coaching feels personal. This page explains, in plain terms, which features use AI, what personal data each one sends, and the choices you have. It sits alongside our Privacy Policy.

1. Who processes the data

Our AI provider is OpenAI. When you use an AI feature, the information needed for that feature is sent to OpenAI's servers, which return a result to us. We then show it to you or save it to your account.

Under OpenAI's API terms, the data we send is used only to generate your result. It is not used to train or improve OpenAI's models. We do not sell your personal data, and we never share your health information with third parties for marketing.

2. Which features use AI, and what they send

• Coach chat: your first name, today's targets and progress, recent weight trend, your latest meal notes and mood, any food allergies and health conditions you told us, and a short recap of your recent chats. This lets the coach answer in context. You can turn off sharing your health conditions in your profile.
• Food, label, menu and ingredient scans: the photo you choose to scan, plus your goal and targets so the estimate fits you.
• Voice notes: the audio is transcribed to text so the coach can read it.
• Body transformation preview: the "before" photo you upload, with your face masked, plus basic body metrics, to generate a preview image.
• Coaching insights, weekly check-in replies and reset messages: your recent progress figures and anything you type into those forms.

3. What we do not keep

Photos you scan and voice notes are processed to return a result and are not stored afterwards. Your body transformation "before" photo is used to make the preview and is not kept for any other purpose.

4. What your coach remembers

Your coach keeps a small set of durable notes so it stays consistent between chats, for example a goal you set in your own words. It never stores medical details: no conditions, symptoms, medications, diagnoses, test results, or current weight or body readings.

You can see the exact list your coach keeps, and delete any item, at What I remember. Nothing is kept that this page would not show you.

5. Please do not share other people's data

When you chat or record a voice note, share only your own information. Please do not enter other people's personal details, full NRIC numbers, or financial information into the coach.

6. The AI does not act on its own

Our AI features answer your request and stop there. They do not take actions on your behalf, do not reach other systems, and cannot change your data by themselves. AI coaching is a supplement to, not a replacement for, professional medical or dietary advice.

7. Your choices

You can at any time:

• Turn off sharing your health conditions with the coach, in your profile, if you would rather they stay in the app and never reach the AI
• Download a copy of your data from Settings
• Delete any note your coach remembers at What I remember
• Delete your account, which removes your data within 30 days
