Terms and Conditions

Last updated: October 8, 2026

Ninja Train is operated by DailyMind LTD, a company registered in Cyprus under registration number HE 439959. These Terms explain the rules for using Ninja Train at https://ninjatrain.app/.

1. Acceptance

By accessing or using Ninja Train, you agree to these Terms. If you do not agree, do not use Ninja Train.

2. The Service

Ninja Train helps you track knee rehabilitation exercises, log training sessions, optionally log discomfort levels, build streaks, and view progress charts.

Ninja Train is software. It does not provide medical advice, coaching, or personal consultations.

We may add, change, limit, suspend, or remove features for security, reliability, legal, product, or business reasons.

3. Eligibility

You must be at least 16 years old to use Ninja Train. You are responsible for keeping your account credentials secure.

4. Medical Disclaimer

I'm not a certified physiotherapist or doctor. Ninja Train provides exercise tracking only — it is not a substitute for professional medical advice, diagnosis, or treatment.

The exercises in the catalog are based on common rehabilitation protocols. Your specific programme should be designed by your healthcare provider. If an exercise causes sharp pain, swelling, or worsening symptoms, stop immediately and consult your doctor.

By using Ninja Train, you acknowledge that you use the app at your own risk and take responsibility for your health decisions.

5. Your Content

You own your training data and any content you create through Ninja Train.

You give DailyMind LTD a limited permission to process your content only as needed to provide the service, prevent abuse, maintain security, debug issues, and comply with law.

6. Acceptable Use

You must not use Ninja Train to:

• break applicable law;
• harass, threaten, or abuse other users;
• probe, overload, attack, reverse engineer, or bypass security of Ninja Train;
• upload malware or harmful code;
• use automation or scraping against Ninja Train unless we explicitly allow it in writing.

7. Payments and Subscriptions

Ninja Train offers a free plan and Pro at EUR 10 per month; the final price including any applicable tax is shown at checkout. New accounts get a 7-day free Pro trial without payment details. Current pricing is shown in the Pricing section.

Paid subscriptions renew automatically unless canceled before renewal. Cancellation stops future charges but does not refund the current billing period.

Payments are processed by Paddle as merchant of record. Paddle may appear on your bank or card statement and handles billing support and refunds under its own policies.

Refunds are handled under the Refund Policy.

8. Third-Party Services

Ninja Train relies on third-party services including Cloudflare, Paddle, and Umami. We are not responsible for third-party service outages, changes, or decisions.

9. Intellectual Property

Ninja Train, including its software, design, brand, interface, exercise catalog content, and related materials, belongs to DailyMind LTD or its licensors. These Terms do not transfer any ownership rights to you.

You must not reverse engineer, decompile, copy, scrape, or attempt to discover source code or non-public APIs without our prior written permission.

10. No Guaranteed Results

Ninja Train helps you track exercises and build consistency. We do not guarantee recovery outcomes, pain reduction, mobility improvement, or any specific health result. Recovery depends on many factors beyond the app.

11. Disclaimers

Ninja Train is provided on an as-is and as-available basis. We do not promise that it will be uninterrupted, error-free, or available at all times.

We do not provide medical, legal, or professional advice through Ninja Train.

12. Limitation of Liability

To the maximum extent permitted by applicable law, DailyMind LTD will not be liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, lost data, or health outcomes.

To the maximum extent permitted by applicable law, DailyMind LTD's total liability for claims related to Ninja Train is limited to the amount you paid in the 12 months before the claim, or EUR 50 if you used Ninja Train for free.

Nothing in these Terms excludes liability that cannot be excluded under applicable law.

13. Indemnity

You agree to protect DailyMind LTD from claims, losses, liabilities, damages, costs, and expenses arising from your use of Ninja Train, your violation of these Terms, or your violation of law or third-party rights.

14. Suspension and Termination

We may suspend or terminate access if we reasonably believe you violated these Terms, created legal or security risk, or misused the service.

You may stop using Ninja Train at any time. You can request account deletion, clear browser storage, or simply stop using the app.

15. Changes to These Terms

We may update these Terms from time to time. The updated date above shows the current version. Continued use after changes means you accept the updated Terms.

16. Governing Law

These Terms are governed by the laws of the Republic of Cyprus, unless mandatory consumer protection law in your country requires otherwise.
