Privacy Policy

E4L app and GEM wearable · Last updated: November 5, 2026

This policy explains what information the E4L mobile app (“the app”) and the GEM wearable collect, why we collect it, who we share it with, and the choices you have. In this policy, “Energy4Life”, “E4L”, “we” and “us” mean Energy4Life, the company that makes the app and the GEM.

1. Information we collect

Account information

When you create an account, we collect your name, email address and password. Your password is handled by our sign-in service and we never see it in plain text. We give your account an ID that links it to your data.

Data from your GEM wearable

When your GEM is paired with the app over Bluetooth, the app collects the readings the GEM records, such as heart rate and heart-beat timing, activity and movement, wrist and arm position, and sleep-related data. It also collects information about the GEM itself, such as its identifier, firmware version and battery level. The app stores this data on your phone until it has been uploaded to our servers.

Health Connect data (Android)

If you choose to connect Health Connect, the app reads heart rate, heart rate variability, resting heart rate, respiratory rate, sleep, steps and exercise sessions (workouts). For each workout the app reads only when it started and ended, the type of exercise and which app saved it; it does not read routes, locations, titles or notes. The app only reads this data and never writes to Health Connect. See Health Connect and Apple Health below.

Apple Health data (iPhone)

If you choose to connect Apple Health, the app reads heart rate, heart rate variability, resting heart rate, respiratory rate, sleep and steps. The app only reads this data and never writes to Apple Health. See Health Connect and Apple Health below.

Scans

A scan can include a short voice recording, where you read a passage aloud, and a photo of your tongue taken with your camera. These are uploaded to our servers and analysed to produce your scan results. If you scan someone else, for example a friend through a share link, you must have their permission first.

The Coach

If you use the Coach, we collect your answers to its intake questions and the messages you send it. If you dictate a message, your phone’s built-in speech recognition service turns your voice into text. On Android this is usually provided by Google.

Notifications

If you allow notifications, we store a push token for your device so we can send you reminders and updates.

App usage and diagnostics

We collect information about how the app is used, such as screens viewed and features used, and crash reports when something goes wrong. This includes your device model, operating system, app version and an app instance identifier. We also record how you found the app, for example from a share link or an ad, to understand which of our campaigns work.

What we do not collect

The app does not collect your location, contacts, photos from your gallery or files.

2. Health Connect and Apple Health

Reading Health Connect or Apple Health data is optional. The app asks for your permission first, and you choose which types of data to share. You can withdraw permission at any time: on Android in Health Connect settings or your phone’s settings, and on iPhone in the Health app (tap your picture, then Apps).

We use Health Connect and Apple Health data only to:

• show your health and wellness results in the app, such as vitality, sleep and recovery;
• count your workouts as active minutes in the activity part of your results, because some watch apps save steps only in blocks of several hours;
• use the data from the wearable you choose in the app (your GEM or your watch) for your results, so the same period of time is not counted twice;
• calculate your personal baselines and improve the accuracy of your results.

We do not sell Health Connect or Apple Health data. We do not use it or share it for advertising or data mining, and we do not use it to decide whether you can get credit, insurance or a job. We do not let people read it, except with your permission, for security reasons, to comply with the law, or where it has been combined and made anonymous.

The use of information received from Health Connect will adhere to the Health Connect Permissions policy, including the Limited Use requirements.

Data received from Apple Health (HealthKit) is used only as described above, in line with Apple’s App Store Review Guidelines. We do not store it in iCloud and we do not share it with third parties, except the service providers that host our servers for us.

3. How we use information

• To run the app: create your account, pair your GEM, sync your data and show your results.
• To analyse your scans and readings and produce your wellness insights.
• To provide the Coach and respond to your messages.
• To manage your subscription and orders.
• To send reminders and updates, if you allow notifications.
• To fix problems, keep the app secure and prevent fraud.
• To understand how the app is used and improve it.
• To measure our advertising, using only non-health events such as signing up.
• To comply with the law.

4. Who we share it with

We do not sell your personal information. We share it only with:

• Service providers who run parts of the app for us under contract, and only for that purpose:
  • cloud hosting and storage providers;
  • our sign-in service;
  • Google Firebase, for app analytics, crash reports and push notifications;
  • Mixpanel and Vercel, for product analytics;
  • our online store provider, for shop orders;
• Meta (Facebook and Instagram): if you arrived through one of our ads, the app tells Meta when you sign up, finish onboarding or buy a subscription, so we can measure that ad. These events never include health data, scans, Coach messages, Health Connect data or Apple Health data.
• People you choose: for example, when you share a link with a friend.
• Legal and safety reasons: when the law requires it, or to protect the rights, safety and property of our users, us or others.
• A business transfer: if Energy4Life is involved in a merger, acquisition or sale of assets, your information may be transferred as part of it. This policy will still apply to it.

5. Phone permissions

The app asks for these permissions only when a feature needs them. You can change them at any time in your phone’s settings.

• Nearby devices (Bluetooth): to find, pair and sync your GEM, including in the background while it is paired.
• Camera: to take the tongue photo in a scan.
• Microphone: to record the voice part of a scan and to dictate Coach messages.
• Notifications: to send reminders and updates.
• Health Connect (Android): to read the health data described above, if you choose to connect it.
• Apple Health (iPhone): to read the health data described above, if you choose to connect it.

6. Keeping and deleting data

We keep your personal information while your account is open, for as long as we need it to provide the app. After that we keep it only as long as the law requires.

Data from your GEM, Health Connect and Apple Health is kept on your phone until it is uploaded and for a short time after, then it is cleared automatically. Uninstalling the app removes the data stored on your phone.

You can delete your data or your whole account at any time:

• in the app: Profile → Your data; or
• by sending a request through our privacy request form.

When you delete your account, we delete or anonymise your personal information, including your health data. We may keep a limited amount of information where the law requires it, for example purchase records.

7. Security

Your data is encrypted while it travels between the app and our servers. Access to it is limited to people and services that need it to run the app.

8. Your choices and rights

Depending on where you live, you may have the right to:

• access the personal information we hold about you and get a copy of it;
• correct it;
• delete it;
• object to or limit how we use it, or withdraw a permission you gave;
• opt out of the use of your information for targeted advertising.

To use any of these rights, use our privacy request form. You can also see Your Privacy Choices and our US State Privacy Notice. We will not treat you differently for using your rights.

9. Children

The app is not meant for children under 13, and we do not knowingly collect personal information from them. If you believe a child has given us personal information, contact us and we will delete it.

10. Wellness, not medical advice

Energy4Life is a general-wellness company. The app, the GEM and the Coach are not medical devices and do not diagnose, treat or prevent any disease. Talk to a doctor about any health concern.
