Privacy Policy
Last updated: March 30, 2026
Auxo ("we", "us", or "our") is committed to protecting your personal information. This Privacy Policy explains what data we collect, how we use it, and your rights regarding that data. By using Auxo, you agree to the practices described here.
Contents
1. Information We Collect
We collect the following categories of information when you use Auxo:
- Account information: email address, display name, date of birth, and biological sex — provided during sign-up.
- Health & fitness data: body weight, height, workout sessions, exercise sets, reps, and weight lifted.
- Nutrition data: food logs, meal types, calorie and macronutrient entries.
- Goals and preferences: fitness goals, dietary preferences, equipment availability, training schedule, and injury history.
- Supplement logs: supplement names, doses, and daily check-in history.
- Hydration logs: daily water intake amounts.
- Apple Health data (optional): with your explicit permission, we read and write weight measurements and workout data to the Apple Health app on your device.
2. How We Use Your Information
Your information is used exclusively to provide and improve Auxo:
- To generate personalised workout plans, meal plans, and coaching responses using AI.
- To calculate and display your macro targets, calorie balance, and progress trends.
- To sync your data securely across your devices via our cloud database (Supabase).
- To provide AI-powered features — food photo analysis, workout recommendations, and coach chat. These features send relevant data to Anthropic (Claude) for processing. Anthropic does not store or train on your data per their enterprise data policy.
- We do not use your data for advertising, do not sell it to third parties, and do not use it to build advertising profiles.
3. Apple Health (HealthKit)
If you enable Apple Health integration, Auxo reads and writes the following HealthKit data types:
- Body Mass (HKQuantityTypeIdentifierBodyMass) — read and write
- Workouts (HKWorkoutType) — write only
Health data obtained from HealthKit is used only to display your metrics within Auxo. It is never shared with advertisers, data brokers, or third parties. It is not used for AI model training purposes.
You can disable Apple Health integration at any time from Settings → Integrations within the app.
4. Data Sharing
We do not sell your personal data. We share data only in these limited circumstances:
- Supabase — stores your account and app data. Supabase is SOC 2 Type II certified and processes data on our behalf as a data processor.
- Anthropic (Claude AI) — receives the minimum data required to respond to your requests (e.g. a summary of your fitness profile for coach chat, or a food photo for nutritional analysis). Anthropic does not retain this data for training purposes.
- Legal requirement — we may disclose data when required by applicable law, court order, or to protect the safety of our users.
No other third parties receive your personal data.
5. Data Retention
Your data is stored for as long as your account remains active. When you delete your account through Settings → Delete Account in the app, all your personal data is permanently and irreversibly removed from our servers within 30 days.
6. Security
We protect your data using industry-standard measures:
- All data is encrypted in transit using TLS (HTTPS).
- Data at rest is encrypted on Supabase-managed infrastructure.
- Authentication uses secure, rotating session tokens — we never store your password in plain text.
- API credentials are stored server-side as secrets and are never included in the app binary.
7. Your Rights
You have the right to:
- Access — request a copy of the data we hold about you.
- Correction — update your personal information via Settings → Edit Profile.
- Deletion — permanently delete your account and all associated data via Settings → Delete Account.
- Portability — contact us to request an export of your data in a machine-readable format.
- Opt-out — disable Apple Health integration at any time via Settings → Integrations.
To exercise any of these rights, contact us at privacy@auxo.app.
8. Children's Privacy
Auxo is not intended for children under the age of 13. We do not knowingly collect personal data from children under 13. If you believe a child under 13 has created an account or provided us their data, please contact us immediately at privacy@auxo.app and we will delete that data promptly.
9. Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices or for legal reasons. When we make material changes, we will update the "Last updated" date above and notify you within the app. Continued use of Auxo after changes are posted constitutes your acceptance of the revised policy.
