1. Who we are

The Perfect Training App is a personalised sports training application designed primarily for youth and amateur football/soccer players. It delivers structured weekly training plans, exercise videos, progress tracking, and tools to help users measure their resting heart rate and calculate personalised heart-rate training zones.

The App is operated by:

NIL Plus d.o.o.
Cesta talcev 67
4000 Kranj
Slovenia

2. Information we collect

We only collect information that we need to operate the App and provide its features.

2.1 Account information (via Sign in with Google or Sign in with Apple)

When you create an account, we receive from your identity provider:

2.2 Profile information you provide during onboarding

2.3 Training and performance data

2.4 Heart-rate measurement data (Target Heart Rate / THR feature)

The App includes a feature that allows you to measure your resting heart rate (RHR) using your phone’s rear camera. We store the resulting numeric measurements:

See Section 4 below for details on how the camera is used and what is — and is not — collected.

2.5 Parental consent information (users aged 16 or under)

If you indicate that you are 16 years old or younger, the App collects:

2.6 Notification preferences

2.7 In-app feedback

If you submit feedback through the App, we store the contents of your message together with your user ID so we can improve the App and respond if needed.

2.8 Technical and diagnostic data

The App uses Firebase services that may collect standard technical data such as:

This information is processed by Google as our infrastructure provider (see Section 7).

3. Information we do not collect

To be clear, the App does not collect any of the following:

4. Camera and flashlight — how the THR feature works

The App requests access to your rear camera and flashlight for one purpose only: to let you measure your resting heart rate using a technique called photoplethysmography (PPG).

When you start a heart-rate measurement:

  1. You place your fingertip over the rear camera lens.
  2. The App turns on the flashlight to illuminate your fingertip.
  3. The camera streams low-resolution video frames only inside your device.
  4. The App analyses brightness changes in the red channel of those frames in real time to detect the rhythm of your pulse.
  5. After roughly 60 seconds, the App calculates a single beats-per-minute (BPM) value.

Important:

5. How we use your information

We use the information described above to:

We do not sell your personal information, and we do not use it for behavioural advertising.

6. Legal bases for processing (EEA / UK users)

7. Service providers and where your data is stored

We use Google Firebase (provided by Google LLC / Google Ireland Limited) as our backend infrastructure, including:

We keep your personal data for as long as your account is active. If you ask us to delete your account, we will delete your personal profile, training history, and heart-rate measurements within a reasonable period, except where we are required to retain certain information to comply with legal obligations, resolve disputes, or enforce our agreements.

10. Children and parental consent

The App is intended primarily for youth athletes. We treat users aged 16 or younger as minors who require parental or guardian consent before they can fully use the App.

When a user indicates an age of 16 or younger during onboarding:

  1. The App asks the user to provide a parent or guardian’s email address.
  2. We use that email address solely to communicate with the parent or guardian and obtain their approval.
  3. Until parental consent is recorded, access to the App’s features may be limited.

If you are a parent or legal guardian and you believe that your child has provided personal information to us without your consent, please contact parents@perfecttrainingapp.com and we will promptly delete the relevant information.

11. Security

We use industry-standard measures to protect your personal information, including TLS encryption in transit, encryption at rest on Google’s infrastructure, and Firebase Security Rules that restrict who can read or write specific records. Despite these measures, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

We may update this Privacy Policy from time to time. When we do, we will update the “Last updated” date at the top of this page and, where the changes are material, notify you in the App or by email. Your continued use of the App after a change becomes effective constitutes acceptance of the updated Policy.
