Terms of Service

Last updated: November 7, 2026

1. Introduction

These Terms of Service ("Terms") govern your use of the ZenFit mobile application ("App") and the website zenfityoga.com ("Website"), provided by NOTJUST.DEV, SL ("Company", "we", "us" or "our"), a company registered at C/ Balmes 129bis 4º 2ª, 08008 Barcelona, Spain.

By downloading, installing or using the App, you agree to these Terms. If you do not agree, do not use the App.

2. The Service

ZenFit offers guided chair yoga: short seated exercise sessions and multi-day programs, shown on video by an instructor ("Linda") with voice guidance, plus progress tracking, reminders, calendar scheduling and optional Apple Health / Health Connect integration. Some content is free; the rest requires a subscription.

Linda is an AI-generated instructor. Her videos and voice are created with artificial intelligence from exercise sequences we design. She is not a real person and does not give personal advice.

3. Health and Exercise Safety

IMPORTANT. PLEASE READ CAREFULLY.

  • ZenFit provides general fitness information. It is not medical advice, diagnosis or treatment, and it is not a medical device.
  • Talk to your doctor before starting any exercise program, especially if you have a heart or lung condition, high blood pressure, osteoporosis, joint replacement, recent surgery or injury, dizziness or balance problems, or if you are unsure whether exercise is safe for you.
  • Exercise at your own risk. Use a sturdy chair without wheels on a non-slip floor. Move slowly, only as far as is comfortable, and never into pain.
  • Stop immediately and seek medical help if you feel chest pain, shortness of breath, dizziness, faintness, or sharp or unusual pain.
  • Estimates shown in the App (such as calories) are approximate.
  • No doctor-patient or trainer-client relationship is created by using the App.

4. Age Requirements

ZenFit is made for adults. You must be at least 16 years old to use the App.

5. Accounts

  • Anonymous account: when you first open the App, an account is created automatically, without email or password. If you delete the App without connecting an account, your progress may not be recoverable.
  • Connected account: you can connect an email address, or sign in with Apple or Google, to keep your progress across devices. You are responsible for keeping your login secure.

6. Cloud Storage

Your profile and progress are stored in the cloud so they can be restored and synced. Health data from Apple Health or Health Connect, calendar events and reminders stay on your device. See the Privacy Policy.

7. Your Data and Our Content

  • Your data remains yours. You give us permission to store and process it only to provide the App, as described in the Privacy Policy.
  • The App's videos, audio, exercise sequences, text, design and branding are owned by NOTJUST.DEV, SL or its licensors. You may use them for your own personal, non-commercial practice. You may not download, record, redistribute or publicly show them.

Reminders, calendar events and health integrations are optional and only work with your permission. You can turn them off at any time in the App or in your device settings.

9. Subscriptions and Payments

9.1 Subscription Plans

Some features of the App require a paid subscription. We offer Weekly and Annual subscription tiers through the Apple App Store and Google Play Store.
