Privacy Policy

Effective date: 13 October 2026

This Privacy Policy explains how EmilyFit Japan ("we", "us") collects, uses and protects your personal information when you use our apps:

• EmilyFit (nutrition and macro tracking, with an AI assistant)
• EmilyFit Workout (workout tracking)
• EmilyFit Lite (guided workouts)
• EmilyFit Coach (tools for coaches and their clients)

All four apps share one account. We handle personal information in accordance with the Act on the Protection of Personal Information of Japan (APPI) and, where they apply to you, other data protection laws.

1. Information we collect

• Account information: your email address and password. Passwords are stored only in hashed form by our authentication provider.
• Profile information: your name, age, gender and height, and the goals you set (for example calorie, macronutrient or step targets).
• Profile photo (optional): if you add one in EmilyFit, EmilyFit Workout or EmilyFit Coach, we store a small copy of it (reduced in the app to a 384 × 384 pixel image) in private storage. Only you, your coach, your clients if you are a coach, and our administrators can see it, through links that expire. You can change or remove it at any time, and it is deleted with your account.
• Health and fitness data: body weight, body fat percentage and steps; the food you log, your recipes and custom foods; and your workouts, sets, routines, programs and personal records.
• Data from Apple Health or Health Connect (EmilyFit and EmilyFit Workout only): if you turn on health sync, we read your weight, body fat percentage and steps. See section 3 for details.
• Meal and label photos (EmilyFit only): when you choose to scan a meal or a nutrition label, the photo you take or select is sent to our AI provider to estimate its nutritional content. We do not store these photos.
• Coach connections: if you connect with a coach, we record the connection and the programs your coach assigns to you.

We do not collect your location, contacts or advertising identifiers. The apps contain no advertising and no third-party analytics or tracking.

The apps also keep some data on your device, such as your settings, an unfinished workout so you can resume it, and cached exercise demonstrations so they work offline. This data stays on your device.

2. How we use your information

• To create and secure your account and sign you in.
• To show your logs, progress and history, and to track your goals.
• To provide AI features in EmilyFit, such as meal and label scanning and the AI assistant.
• To let you and your coach work together, if you choose to connect with one.
• To send you service emails, such as account confirmation, password reset and coach invitations.

We do not sell your personal information, and we do not use your health data for advertising.

3. Health Connect and Apple Health

EmilyFit and EmilyFit Workout can read data from Health Connect (Android) and Apple Health (iPhone). This only happens if you turn on health sync in the app and grant permission on your device.

• What we read: body weight, body fat percentage and steps, including your past records of these data when you first turn on sync, so your history is complete.
• Read only: we never write, change or delete data in Health Connect or Apple Health.
• How we use it: only to show it to you in the apps (your weight, body fat and steps, your progress charts and your program goals). We save a daily total of each value to your account so you can see it on your other devices.
• Who can see it: you, and your coach if you have chosen to connect with one (see section 4).
• What we never do: we do not sell these data, use them for advertising, or share or transfer them to anyone else, except our service providers that store them for us (section 5) and where the law requires it. People do not read these data except to provide the service to you or where the law requires it.
• Turning it off: you can turn off health sync at any time in the app settings, or remove the permission in your device settings. Data already saved stays in your account until you delete it or delete your account.

The use of information received from Health Connect follows the Health Connect Permissions policy, including the Limited Use requirements. Data from Apple Health is never used for advertising or shared with third parties for marketing, as required by Apple.

4. Sharing with your coach

If you accept a connection with a coach, that coach can see your profile (including your profile photo, if you added one) and the fitness and nutrition data you log, and can assign you programs and routines. You can remove your coach at any time from the app. Coaches only see the data of the clients who have connected with them. If you are a coach, your clients can see your name and your profile photo.

5. Service providers

We use the following providers to run the apps. They process your data only on our behalf, to provide their service:

• Supabase: authentication, database and file storage. Your account and app data are stored on Supabase servers in Tokyo, Japan.
• Google (Gemini API): AI features in EmilyFit. When you use them, the relevant content (for example a photo, or your recent meals and targets) is sent to Google to generate a response.
• Resend: delivery of service emails.
• Google (Firebase Hosting): hosting of our websites and web apps.

When you scan the barcode of a product in EmilyFit Macros, our server looks up that barcode in Open Food Facts, an open food database. Only the barcode is sent, never your account or other data. The product information comes from Open Food Facts and is available under the Open Database License.

Google and Resend may process the data they receive on servers outside Japan, including in the United States. When we transfer personal information abroad, we do so as permitted by the APPI and rely on providers that protect it with appropriate safeguards.

6. Security

All data sent between the apps and our servers is encrypted in transit (HTTPS/TLS). Access to your data in our database and file storage is restricted so that each user can only reach their own data, plus the data of clients who have connected with them if they are a coach. Profile photos are kept in private storage and are only shown through links that expire.

7. Data retention and deletion

We keep your data while your account is active. You can delete your account at any time. This permanently deletes your profile and all the data associated with it; we do not keep backup copies. See our Account Deletion page for how to do it and what is deleted.

8. Your rights

You can view and correct most of your information directly in the apps. You may also ask us to disclose, correct, stop using or delete your personal information by contacting us at the address below. We will respond within a reasonable time and as required by law.

9. Children

The apps are not intended for children under 16, and we do not knowingly collect personal information from them. If you believe a child has given us personal information, please contact us and we will delete it.

10. Changes to this policy

If we make significant changes to this policy, we will update the effective date above and, where appropriate, let you know in the apps.
