Privacy Policy
Effective date: August 28, 2026
This Privacy Policy explains what personal data NutraFlow ("NutraFlow", "we", "us") collects, how we use it, who we share it with, and the choices and rights you have. It applies to the NutraFlow mobile app and this website.
The privacy information shown on the App Store and Google Play product pages summarizes the practices described here. If you do not agree with this policy, please do not use NutraFlow.
1. Who we are
NutraFlow is an independently developed nutrition and fitness tracking app. We are the controller of the personal data described in this policy. For any privacy question or request, contact us using the details in the Contact us section below.
2. Data we collect
We only collect data needed to run the app and provide its features.
| Category | What it includes | Why we collect it |
|---|---|---|
| Account information | Your name and email address, and the password you set (the password is handled by our authentication provider and is not visible to us). | To create and secure your account and to contact you about your account or support requests. |
| Account identifier | A unique user ID assigned to your account, and your subscription/entitlement status. | To link your data to your account, sync it across your devices, and unlock features you are entitled to. |
| Profile, health and fitness data | Age, gender, height, weight, activity level, fitness goal, dietary preferences, and the calorie and macronutrient targets calculated from them. | To personalize your daily targets, insights, and recommendations. |
| Nutrition and meal data | Meals you log, meal type and time, text descriptions, estimated calories and macronutrients, nutrition scores, AI feedback, and your meal history. | To provide meal tracking, analysis, history, and progress features. |
| Workout and progress data | Workouts you log (type, duration, estimated calories burned, notes), streaks, and milestones you reach. | To provide the training log and progress and streak tracking. |
| Photos and images | Photos you choose to take or select for meal or nutrition label analysis, and an optional profile photo. | Meal and label photos are used to identify food and estimate nutrition. A profile photo is used only to personalize your profile. |
| Barcode data | Product barcodes you scan. | To look up product nutrition information. Barcodes are sent to a public food database and do not include personal data. |
| Purchase data | Records of subscription purchases, renewals, and status. | To manage NutraFlow Pro access and restore purchases. Payment card details are handled by Apple or Google and are never received by us. |
NutraFlow does not use advertising identifiers, does not include third-party advertising or analytics tracking SDKs, and does not track you across other companies' apps or websites.
3. How we use your data
- Provide core functionality: create your account and store and sync your profile, meals, workouts, and progress across your devices.
- Analyze meals and nutrition labels using AI to identify food and estimate calories and macronutrients.
- Personalize your calorie and macro targets, nutrition scores, and insights based on your profile and goals.
- Manage your NutraFlow Pro subscription and entitlements, and let you restore purchases.
- Send reminders and notifications that you enable. These are scheduled locally on your device.
- Maintain the security and reliability of the app and troubleshoot problems.
- Respond to your support requests and communicate about your account.
- Comply with legal obligations.
We do not use your meal, health, or fitness data for advertising or to build advertising profiles.
4. AI meal and nutrition analysis
When you analyze a meal or a nutrition label, the photo and any text description you provide are sent to our AI processor (Anthropic, the provider of the Claude API) to return a food identification and nutrition estimate. This data is processed to fulfill your request. Under Anthropic's API terms, this data is not used to train their models. If no AI service is available, the app falls back to a local estimate based on your text description.
5. Who we share data with
We do not sell your personal data, and we do not share it for advertising. We share data only with service providers that help us run NutraFlow, and only as needed:
| Provider | Purpose | Data involved |
|---|---|---|
| Google Firebase (Authentication, Cloud Firestore, Cloud Storage) | Account sign-in, and hosting and syncing your app data and images. | Account information, account identifier, profile and health data, nutrition and workout data, photos. |
| Anthropic (Claude API) | AI analysis of meal and nutrition label photos and descriptions. | Meal/label photos and text descriptions you submit for analysis. |
| RevenueCat | Managing and validating subscription purchases and entitlements. | Account identifier and purchase/subscription status. |
| Apple App Store / Google Play | Processing subscription payments and billing. | Purchase transactions. Payment details are handled entirely by the store. |
| Open Food Facts | Looking up product nutrition information from a scanned barcode. | The barcode number only. No personal data. |
We may also disclose data if required by law, to enforce our terms, or to protect the rights, safety, or property of users or the public. If the app is ever transferred to another owner, your data may be transferred as part of that transaction, subject to this policy.
6. International transfers
Our service providers may process and store data in the United States and other countries. Where required, we rely on appropriate safeguards (such as standard contractual clauses) for these transfers.
7. Data retention
We keep your account and app data for as long as your account is active. When you delete your account, your profile and meal data are deleted from our active database, and your account is removed from our authentication system. Residual copies may remain in encrypted backups for a limited period before being overwritten. Photos you uploaded may persist in storage for a short additional period; you may email us to request their removal.
8. Your rights and choices
- Access and correction: You can view and edit your profile, meals, and workouts directly in the app.
- Deletion: You can delete your account and its data in Profile → Delete Account, or by emailing us.
- Withdraw consent: You can stop providing photos, disable notifications in your device settings, or stop using the app at any time.
- Data portability and other rights: Depending on your location (for example, the EEA, UK, or California), you may have additional rights, including to request a copy of your data or to object to certain processing. Contact us to exercise them.
We do not discriminate against you for exercising your privacy rights. To make a request, contact us using the details in the Contact us section below. You also have the right to complain to your local data protection authority.
9. Security
Data is encrypted in transit, and access to stored data is restricted through our providers' authentication and access controls. No method of transmission or storage is completely secure, but we work to protect your information and to limit what we collect.
10. Children
NutraFlow is not directed to children under 13 (or under the minimum age required in your country), and we do not knowingly collect data from them. If you believe a child has provided us data, contact us and we will delete it.
11. Changes to this policy
We may update this Privacy Policy from time to time. When we make material changes, we will update the effective date above and, where appropriate, notify you in the app. Continued use of NutraFlow after an update means you accept the revised policy.
