Privacy
Policy

Your privacy is important to us. In this Privacy Policy, we explain how we collect, use and protect your personal data in the Tsemppi service.

This is a translation of the original Finnish document. In case of any discrepancy, the Finnish version shall prevail.

1. Data controller

The processing of your personal data is the responsibility of:

Tsemppi Fitness Oy

  • Business ID: 3377898-6
  • Address: Kolmas Linja 30 B, Helsinki
  • Email: info@tsemppiapp.fi

2. What data we collect

We collect the following data in order to provide the service:

Basic information

Name, email address, date of birth, gender

Account information

Username, password (encrypted), profile picture

Training data

Training history, workouts, weights, repetitions, progress data

Body data

Height, weight, limitations (optional)

Health and fitness data

Workouts you import from Apple Health or Health Connect: type, duration, distance, energy burned, heart rate and elevation gain (optional)

Location data

The GPS route of outdoor workouts, and your location for gym search (optional, see section 5)

Usage data

How you use the application, device information, IP address

Note: Heart rate is health data. We store it only if you connect Apple Health or Health Connect and import workouts from there, and you can delete imported workouts at any time. Training, body and health data are optional, and you decide what you save.

3. Artificial intelligence and data processing

Tsemppi uses artificial intelligence to create personalised training programmes. Here we explain exactly how the AI works:

What data the AI uses

  • •Goal: Muscle growth, strength, fat loss or performance
  • •Level: Beginner, intermediate or advanced
  • •Training frequency: How many times a week you want to train
  • •Workout duration: Target time per workout
  • •Equipment: Gym, basic equipment or home training
  • •Limitations: Any injuries or limitations (knee, shoulder, back, hip)

Third-party AI service

To generate training programmes, we use OpenAI’s GPT-4o-mini model. When you create a new training programme:

  • •We send OpenAI only the onboarding information listed above (goal, level, frequency, duration, equipment, limitations)
  • •We do not send personal identifiers such as your name, email address or username
  • •OpenAI does not use the data to train its models when the service is used via the API
  • •The data is processed in accordance with EU data protection regulations

Data storage

  • •All user data is stored on our own servers within the EU
  • •Generated training programmes are saved to your account, not with OpenAI
  • •Training history and workouts are kept only in our own database

Limitations of AI: The AI creates a training programme based on the information you provide and our existing exercise database. AI does not replace professional advice, and we recommend consulting a doctor before starting a new exercise programme, especially if you have health-related limitations.

4. Strength level and muscle points

Tsemppi calculates metrics describing your progress based on your training data:

Strength level metric

The strength level is based on standardised powerlifting formulas and takes into account:

  • •Weights lifted: Maximum lifts in different exercises
  • •Body weight: Relative strength in relation to body weight
  • •Gender: Comparison with gender-specific averages

Muscle map and progress

The muscle map visualises the load of your workouts:

  • •Intensity: Calculated based on sets, repetitions and weight
  • •Target muscles: Each exercise targets specific muscle groups as defined in our exercise database
  • •PR tracking: Personal records are saved automatically

Note: These metrics are indicative and are intended to motivate you and to track progress. They are not medical assessments.

5. Application permissions

Tsemppi may request the following permissions on your device. Each permission is optional, and you can manage them in your device settings:

Camera
Optional

We use the camera to take a profile picture and to save workout videos and progress photos to your profile.

Notifications
Optional

We use notifications to remind you of workouts, to notify you of community activity (likes, comments, followers) and of replies to support messages.

HealthKit (iOS)
Optional

The HealthKit integration enables training data to be synchronised with Apple’s Health app, so that you can track all your physical activity in one place.

Health Connect (Android)
Optional

The Health Connect integration brings workouts from your watch and other fitness apps into your training history (type, duration, distance, energy burned, heart rate and elevation gain), and saves the workouts you finish in Tsemppi and your weight to Health Connect. We read only the data types you allow, and we never use them for advertising. We do not read workout routes from Health Connect.

Location
Optional

When you start an outdoor workout, Tsemppi records the GPS route, distance and pace, including while the screen is locked, and stops as soon as you finish. The route coordinates stay on your phone: our server stores only the distance, splits and the shape of the route, without coordinates. In gym search, your location is sent to Google’s place search to find gyms near you, and it is not stored.

Note: The application works fully without these permissions. We only request permission when you use the feature in question for the first time.
