Privacy Policy

Sugar AI ("we", "us", "our") respects your privacy. This policy explains what information we collect when you use the Sugar AI mobile app, how we use it, and the choices you have.

What we collect

• Account info: your email address and a securely-hashed password. If you sign in with Apple or Google, we receive a unique identifier and (where you allow) your email address.
• Meal data: photos you take of meals, the foods our AI identifies, the carbohydrate / nutrition estimates, and the glucose-rise estimates generated for those meals.
• Glucose data: if you choose to connect Apple Health or LibreLinkUp, we read your glucose readings to compare against our estimates and personalise future ones.
• Subscription status: whether you have an active free trial or paid subscription. We do not store your payment card details.
• Usage data: anonymous analytics about which features you use, so we can improve the app.

How we use your data

• To provide the core scan-and-predict experience.
• To improve your personal estimates over time using your own logged glucose responses.
• To respond to your support requests.
• To enforce subscription limits and verify entitlements.

What we don't do

• We never sell your data to third parties.
• We never share your meal photos or glucose readings with advertisers.
• We do not use your data to train any external AI models beyond what's required to identify foods in your photos.

Third-party services

• Google Gemini AI processes your meal photos to identify foods. We send only the photo and prompt — we do not attach your name, email, or account ID to those requests.
• Supabase stores your account, meals, and glucose data securely.
• RevenueCat & Apple process subscription payments. We never see or store your card details.
• Apple HealthKit data stays on your device unless you explicitly grant Sugar AI permission to read your glucose readings. We never write data back to HealthKit.
• LibreLinkUp: if you connect your account, we authenticate against Abbott's LibreLinkUp service to fetch your glucose readings. Your LibreLinkUp credentials are stored on your device using the operating system's secure storage where available, and are never sent to our servers.

Data retention

We retain your account and meal data for as long as your account is active. If you delete your account, we permanently remove your personal data within 30 days, except where we are required to keep limited records for legal, accounting, or fraud-prevention purposes.

Your rights

You can, at any time:

• Access and view all your data inside the app.
• Delete your account from Settings → Account → Delete Account. This permanently removes your data within 30 days.
• Disconnect Apple Health or LibreLinkUp from Connect to stop further glucose syncing.
• Contact us to request a copy or correction of your data.

Children

Sugar AI is not intended for children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will delete it.

International users

Sugar AI is operated from the United Kingdom. If you use the app from outside the UK, you understand that your information may be processed in the UK and other countries where our service providers operate.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by the "Last updated" date above and, where appropriate, surfaced inside the app.
