Fitrize

Privacy Policy

Last updated: 4 November 2026

This policy explains what information the Fitrize app ("Fitrize", "we", "us") collects, why we collect it, and the choices you have.

In short: we keep only what you enter in the app, and your step count if you allow it, so it can show you your own progress. AI features send the data they need to third-party AI services, only after you agree. We do not sell your data, we show no ads, and we never use your health data for advertising.

1. Information you give us

Account details: your name, email address and a password (stored securely by Google Firebase Authentication; we cannot see it).
Profile details you enter: age, gender, height, weight, body fat (optional), activity level, fitness goal, training experience, and any health conditions, injuries, pain level or notes you choose to add.
Fitness details you log: meals and nutrition, water intake, sleep hours, workouts, sets and personal records, weigh-ins, body fat and waist measurements.
Feedback: any rating and message you send from the Feedback screen.
AI features: photos of meals or of you exercising, meal descriptions, and questions you ask the coach. Photos are sent to an AI service to be analysed and are not saved by Fitrize; we save only the result, such as the meal's estimated nutrition or the form tips. Your coach conversation and AI plans are saved so you can see them again.

2. Information we do not collect

Health data other than your daily step count.
Your SMS messages, contacts or location.
Your photo library. Fitrize only gets a photo you pick or take for an AI feature.
Advertising IDs. Fitrize has no ads and no ad trackers.

3. Information collected automatically

Step count (with your permission): Fitrize reads your daily step count from Health Connect on Android or Apple Health on iPhone. It only reads steps and never writes anything back. You can turn this off at any time in Health Connect or the Health app. Fitrize's use of information received from Health Connect follows the Health Connect Permissions policy, including the Limited Use requirements.
Basic technical data: like other online services, Google Firebase may process technical data such as IP address and device type to deliver the service securely.

4. How we use your information

To show your dashboard, nutrition, workouts, habits, steps, analytics and progress inside the app.
To work out your daily calorie, protein and activity targets from your profile.
To keep your data in sync across your devices and back it up.
To sign you in, change your password and keep your account safe.
To run AI features you choose to use: estimating a meal's nutrition, making meal and workout plans, answering your questions in the coach, checking your exercise form and writing your progress insight.

Targets and numbers in Fitrize are worked out from what you enter. They are estimates only and are not medical advice.

5. Where your data is stored

Your data is stored with Google Firebase (Cloud Firestore and Firebase Authentication), which may store data on servers outside your country. Data is encrypted in transit and at rest by Google. Some settings are also kept on your phone.

Only you can read your data when signed in. Access is limited by security rules tied to your account.

6. Sharing

We do not sell or rent your information. We share it only:

With Google Firebase, which runs the app's sign-in and storage for us.
With AI services, only if you allow it: when you use an AI feature, Fitrize sends what that feature needs to one of these services: Google Gemini, Groq or OpenRouter (which may pass the request to the AI model provider it routes to). This can include meal photos and descriptions, exercise photos, your questions to the coach, your fitness profile (such as age, gender, height, weight, goal and any notes you added), and recent meals, workouts and progress. Your name, email address and password are never sent. Each service handles this data under its own terms and privacy policy, linked above.
If required by law, or to protect the rights and safety of users and the service.

7. Your choices and rights

See and change: you can view and edit your profile and the entries you logged in the app.
Step access: turn it on or off in Health Connect or the Health app.
AI features: Fitrize asks before it first sends anything to an AI service. You can turn this off at any time in More → Profile → AI features. When it is off, no data is sent to AI services.
Delete: in the app, go to More → Profile → Delete account. This permanently deletes your account and all your Fitrize data straight away. This cannot be undone. You can also email us from your account's email address with the subject "Fitrize account deletion", and we will do it for you within 30 days.

You can also email us to ask for a copy of your data.

8. How long we keep data

We keep your data while your account is active. When you delete your account, your data is removed from our live systems. Backups held by Google are cleared on their normal schedule.

9. Children

Fitrize is not meant for children under 13, and we do not knowingly collect their information. If you think a child has given us information, contact us and we will delete it.

10. Changes to this policy

We may update this policy. We will change the "Last updated" date above and, for important changes, let you know in the app.
