Privacy Policy

This policy explains what SHREDO LLC, the company behind the Shredo app ("Shredo," "we," "us"), collects, why, and the control you have. The short version: your data exists to score your plates and track your progress — we don't sell it, we don't run ads, and your photos aren't used to train AI models.

1. Information we collect

Information you provide

• Profile & goals — answers from onboarding: sex, date of birth, height, weight, activity, goals, eating habits, and coach preferences.
• Plate photos — the meal photos you scan. They are uploaded for AI analysis of your plate to produce your results and are stored on your device.
• Scan results & weigh-ins — detected foods, scores, estimated nutrition, and the weights you log.
• Support messages — whatever you send us at support@shredo.app.

Collected automatically

• Usage analytics — app events (screens viewed, scans completed), device type, OS version, and a random analytics identifier, via PostHog. You can turn this off in Profile → Preferences ("Share anonymous usage").
• Basic technical data — crash reports and logs needed to keep the Service working.

From other services (with your permission)

• Apple Health — your daily step count, read-only, used on your device to show progress. We do not write to Health and do not use Health data for advertising. Revoke access anytime in the iOS Health app.
• Apple / Google sign-in — if you sign in, we receive your account identifier and email address from the provider to create your Shredo account.

2. How we use your information

• To provide the Service — analyze your photos with AI, compute your Plate Score and guidance, build your plan, write the voice coach's reaction to each scan, and sync your history to your account.
• To improve Shredo — aggregated, de-identified analytics about how features are used.
• Security & integrity — protect accounts, enforce our acceptable-use rules, and comply with law.

3. Who processes your data

We use a small set of service providers, each only for the purpose listed:

• Anthropic — AI analysis of your plate photos to produce your results, and the voice coach's written reaction to each scan (using your goals, goal weight, today's plates, streak, and steps).
• ElevenLabs — turns the voice coach's reaction into speech when voice is on. It receives only the text of that reaction. Turn voice off anytime in Profile → Voice Coach.
• Supabase — database, authentication, and photo storage (accounts and history).
• PostHog — usage analytics (optional; opt out in the app).
• Expo (EAS Hosting) — hosting for our analysis service and these pages.
• Apple / Google — sign-in, and payment processing for subscriptions (handled by the app store; we never see your card details). Subscription status is processed by RevenueCat on our behalf.
• Google Maps / Google Places — when you use Eating Out, your approximate location is used to find restaurants near you; restaurant names, photos, and details are provided by Google. Your location is used for lookups and is not sold.

4. Your data is isolated

Records are protected with row-level access controls so that you can only ever access your own data.

5. Retention & deletion — you're in control

We keep your data while you use the app, and you can remove it at any time:

• Delete everything, anytime. Profile → "Delete Account" permanently erases your profile, scans, photos, and weight logs from our servers. This cannot be undone.
• Turn off analytics in Profile → Preferences ("Share anonymous usage").
• Revoke Apple Health access in the iOS Health app.
• Sign out — your history stays on your device; the account keeps its backup until you delete it.

6. Security

Data is transmitted over encrypted connections (TLS) and stored with per-user access controls. No system is perfectly secure, but we deliberately collect little and scope every record to its owner.

7. Children

Shredo is not directed at children and is intended for users 13 and older (teens with a parent or guardian's involvement). We do not knowingly collect data from children under 13 — if you believe a child has provided us data, contact us and we will delete it.

8. International transfers

Our servers are located in the United States. If you use Shredo from elsewhere, your information is processed in the US, where privacy laws may differ from your country's. We apply the same protections described here to all users.

9. Your privacy rights

Depending on where you live (including California under the CCPA and the EEA/UK under the GDPR), you may have rights to access, correct, delete, or export your personal information, to object to or limit certain processing, to withdraw consent, and to complain to your local data-protection authority. Most of these are built into the app (deletion, analytics opt-out). For anything else, email support@shredo.app — we respond to verified requests within 30 days and never discriminate against you for exercising your rights. Where GDPR applies, our lawful bases are contract (providing the Service you asked for), consent (analytics, Health access), and legitimate interests (security and service improvement).

10. Not medical advice

Shredo provides estimates and general guidance from your photos and weigh-ins. It is not medical advice, and results vary from person to person. Consult a healthcare professional before making health or diet changes.

11. Changes to this policy

We may update this policy as the app evolves. We'll revise the "Last updated" date above and, for significant changes, notify you in the app.
