Terms of
Service

Welcome to Tsemppi! These Terms of Service set out how you may use the Tsemppi application and service. By using Tsemppi, you accept these terms.

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

1. Service provider

The Tsemppi application and service are provided by:

Tsemppi Fitness Oy

  • Business ID: 3377898-6
  • Address: Kolmas Linja 30 B, 00530 Helsinki, Finland
  • Email: info@tsemppiapp.fi

2. Description of the service

Tsemppi is an AI-assisted training application that:

Creates personalised training programmes for you with the help of artificial intelligence

Tracks your progress visually as a muscle map

Provides a community where you can share workouts and encourage others

Helps you train effectively and systematically

AI functionality: In generating training programmes, we use OpenAI’s artificial intelligence service. Further information on the data used by the AI can be found in our Privacy Policy.

We develop the application continuously and add new features to it. Some features may be marked as experimental, in which case they may not work as expected in all situations.

3. Who may use Tsemppi

You may use Tsemppi if you:

  • ✓Are at least 15 years old
  • ✓Accept these Terms of Service and the Privacy Policy
  • ✓Do not use the service for unlawful or harmful activities

If you are under 18, you need your guardian’s consent to take out a paid subscription. The guardian is responsible for purchases made by a minor.

4. Account creation and responsibility

Creating an account:

  • •You must provide accurate and up-to-date information when registering
  • •You are responsible for the security of your account password
  • •Notify us immediately if you suspect that the security of your account has been compromised

Use of the account:

  • •One account is intended for one person
  • •You may not share your account with others
  • •You are responsible for all activity that takes place through your account

5. Subscription and pricing

Tsemppi is a paid subscription service. A subscription gives you access to the application’s paid features for the duration of the subscription period.

Monthly

Billing period: Monthly

EUR 9.99
Annual

Billing period: Annually

EUR 69.99

Prices include VAT. The application always shows the price in force before purchase. Prices may vary by country according to currency and tax rate.

Free use at the start. You can create an account, generate a training programme and complete one workout without a subscription. After that, the application asks you either to start the free trial or to take out a subscription before you can continue using the paid features.

Price changes. We may change subscription prices. We will notify you of a price change at least 30 days before it takes effect, by email or in the application. The change applies only to a billing period starting after the notice. If you do not accept the new price, you may cancel your subscription before the change takes effect.

6. Trial period and automatic renewal

Trial period. New users are offered a 7-day free trial. The trial can be started once the free workout has been used and the application asks for a subscription. With a promotional code the trial may be longer. The trial is available once per user.

Automatic renewal. Your subscription renews automatically at the end of each billing period unless you cancel it before the period ends. This also applies to the trial period:

  • •The trial converts to a paid subscription automatically when it ends
  • •You are charged on the last day of the trial
  • •You may cancel at any time during the trial without being charged
  • •If you cancel during the trial, access continues until the end of the trial period

Payment. Subscriptions are billed through the app store you downloaded the application from: Apple’s App Store or Google Play. Payment is charged to the payment method linked to that account. We do not process or store your card details. If a payment fails, the app store may retry the charge in accordance with its own terms, and the subscription may be suspended until payment succeeds.

7. Cancellation

You may cancel your subscription at any time. Cancellation is done in the app store through which the subscription was taken out, not in the Tsemppi application:

iPhone and iPad:

Settings → your name → Subscriptions → Tsemppi → Cancel subscription

Android:

Google Play → profile picture → Payments and subscriptions → Subscriptions → Tsemppi → Cancel subscription

Cancellation must be made at least 24 hours before the end of the billing period to avoid the next charge. Access continues until the end of the period you have paid for. We cannot cancel your subscription on your behalf, because the billing agreement is with the app store.

Note: deleting your account in the application does not cancel your subscription. Cancel the subscription in the app store before deleting your account, otherwise billing will continue.

8. Refunds and right of withdrawal

As a consumer you are in principle entitled to a 14-day right of withdrawal in distance contracts. For digital content, however, the right of withdrawal lapses once delivery of the service has begun with your express consent before the withdrawal period has ended and you have acknowledged that the right lapses. You give this consent at the point of purchase in the app store.

Refunds are handled by the app store through which the subscription was taken out:

We cannot grant a refund directly, because we do not receive the payment ourselves. If the app store rejects your refund request and you believe you are entitled to one, contact us at info@tsemppiapp.fi. We will look into it and may refund the payment separately if the request is justified.

An unused part of a subscription period is not refunded as a rule.

9. Employee wellness benefits

Tsemppi can also be subscribed to through Finnish employee wellness benefit providers (Epassi and Edenred). In that case:

  • •The subscription and payment are governed by that provider’s terms, not the app store’s
  • •Your employer and the benefit provider are responsible for granting the benefit, its scope and its validity
  • •Access to Tsemppi ends when the period paid for through the benefit ends
  • •These Terms of Service apply to your use of the application in this case as well

If your employment or benefit entitlement ends, you can continue using Tsemppi by taking out an ordinary subscription through the app store. Your training history is preserved.

10. Permitted and prohibited use

  • ✓Use Tsemppi for your personal training

14. Limitations of liability and safety

Training safety:

Tsemppi provides AI-assisted training guidance and progress tracking. We recommend that you consult a healthcare professional before starting a new training programme, especially if you have health problems or injuries. Always listen to your body and stop the workout if you experience pain or discomfort.

Limitations of AI:

AI-generated training programmes are indicative and are based on the information you provide and on general training principles. They do not replace the advice of a personal trainer or a healthcare professional. The strength level and muscle point metrics are motivational tools, not medical assessments.

Limitation of liability:

We are not liable for indirect damages such as lost profit, loss of data or business interruption. Our liability is limited to the amount you have paid for Tsemppi during the twelve (12) months preceding the event giving rise to the damage.

This limitation does not apply to damage caused by us intentionally or through gross negligence, to personal injury, or to any other liability that cannot be limited under mandatory consumer protection legislation.
