Terms and Conditions

1. Agreement

By creating an account or using Nostos Fit, you agree to these Terms. If you do not agree, do not use the app.

2. The service

Nostos Fit provides fitness tracking tools including workout logging, nutrition and macro tracking, step tracking via Health Connect (with your permission), and gamified progression (XP and levels).

The optional 360° body scan is not required to use the app. It unlocks extra features such as the home turntable display, muscle overlay, and workout volume comparisons. The app is for general fitness and wellness, not medical care.

3. Eligibility

You must be at least 18 years old to use the optional 360° body capture feature. You must be old enough to consent in your jurisdiction for other features (at least 16 where required). You are responsible for the accuracy of information you enter.

4. Account

You are responsible for keeping your login credentials secure. Notify us at support@nostosfit.com if you suspect unauthorized access.

You may delete your account in Profile then Settings. Deletion is permanent and removes your account data, workouts, diet logs, steps history, social data, and all 360° body images and metrics from our systems, as described in the Privacy Policy.

5. Health and fitness disclaimer

Body fat %, muscle mass, circumferences, calorie targets, and XP are estimates for motivation and tracking. They are not diagnoses and may differ from clinical or DEXA measurements.

Consult a qualified professional before starting or changing exercise or diet programs, especially if you have health conditions, are pregnant, or take medication.

Assumption of risk. Physical activity carries inherent risk. You use the app and follow any in app guidance at your own risk.

6. Body scan and camera

The optional 360° body scan uses your device camera. Before your first capture you must confirm you are 18 or older and consent to camera use. You must only scan yourself (or someone you have legal permission to photograph). Do not use the feature where photography is prohibited.

Pose and segmentation run on your device using MediaPipe, and we do not upload raw camera frames for cloud inference. When signed in, processed turntable images and session metadata may sync to your cloud backup, as described in the Privacy Policy.

7. Social and compare features

Your profile visibility is private by default after you create an account or complete a new 360° scan. Nothing is shared until you manually change visibility to friends only or public. You are responsible for what you share when you change visibility settings.

8. Acceptable use

You agree not to:

• Reverse engineer, scrape, or abuse the service or other users' data.
• Upload unlawful, harassing, or infringing content.
• Attempt to bypass security, row level access controls, or rate limits.
• Use the app to provide medical services to third parties.

We may suspend or terminate accounts that violate these Terms.

9. Intellectual property

The app, branding, and original content are owned by Nostia Labs or its licensors.

Exercise GIFs are licensed from Gym Visual under their Non Exclusive Commercial Royalty Free License. You may use the app as intended, but you may not extract, resell, redistribute, or republish those animation files. Copyright remains with Gym Visual and its licensors.

Third party food data remains subject to its respective licenses.

You retain rights in content you create (e.g. workout logs). You grant us a license to store and process that content to operate the service.

10. Subscriptions and payments

If paid features are offered later, additional payment terms will apply at checkout. Current builds may show placeholder paywall UI without billing.

11. Privacy

Our Privacy Policy explains how we handle personal data. It is incorporated into these Terms by reference.

12. Disclaimers

THE APP IS PROVIDED "AS IS" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING FITNESS FOR A PARTICULAR PURPOSE AND NON INFRINGEMENT, TO THE MAXIMUM EXTENT PERMITTED BY LAW.

13. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, NOSTIA LABS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, PROFITS, OR GOODWILL, ARISING FROM YOUR USE OF THE APP.

Our total liability for any claim relating to the app will not exceed the amount you paid us in the twelve months before the claim (or EUR 50 if you paid nothing).

14. Indemnity

You agree to indemnify Nostia Labs against claims arising from your misuse of the app or violation of these Terms, to the extent permitted by law.

15. Changes

We may update these Terms. Continued use after the "Last updated" date means you accept the revised Terms. Material changes may be notified in app.

16. Governing law

These Terms are governed by the laws of the Netherlands, without regard to conflict of law rules. Mandatory EU consumer protection rules may also apply where required. Disputes shall be subject to the courts of the Netherlands unless your local law requires a different forum.
