Legal

Terms of use.

Sitria is owned and operated by ARKFLOW, INC. These terms are an agreement between you and ARKFLOW, INC. — please read them before using the service.

Effective date: November 11, 2026 · Version 1.1

1. Acceptance of terms

By accessing or using Sitria — including our website at sitria.app, our mobile applications, and any related features (together, the "Service") — you agree to these Terms of Use ("Terms"). If you do not agree, do not use the Service.

2. The service

Sitria is a wellness application that connects an alarm with a short isometric exercise — the wall sit — to help you build a consistent morning routine. The Service may include guided sessions, depth feedback using your device's camera, progress tracking, and related features.

Features, availability, and pricing may change over time. The Service is provided for personal, non-commercial use.

3. Eligibility

You must be at least 18 years old, or the age of legal majority in your jurisdiction, to use the Service. If you are younger, you may use Sitria only with the supervision and consent of a parent or legal guardian who agrees to these Terms on your behalf.

4. Health and wellness disclaimer

Sitria is a wellness tool, not a medical device, and it does not provide medical advice. It does not diagnose, treat, cure, or prevent any disease or condition, and it is not a substitute for professional medical care. Always seek the advice of a physician or other qualified health provider with any questions about your health, and never disregard or delay seeking medical advice because of something you read in or through the Service.

Isometric exercise briefly raises blood pressure during the hold. Consult your doctor before starting if you have high or uncontrolled blood pressure, heart disease, are pregnant, or have been told to avoid straining exercise. Stop immediately and seek help if you feel dizzy, have chest pain, or experience unusual shortness of breath.

Sitria does not promise any particular health outcome. Individual results vary, and exercise content in the Service is based on published research that may not apply to your personal circumstances. Keep taking any medication exactly as prescribed.

5. Camera and your data

Depth feedback relies on your device's camera. Camera frames are processed on your device and are not uploaded, stored on our servers, or shared. For details on how we handle information generally, see our Privacy Policy.

You are responsible for choosing a safe place to exercise and for keeping the area around you clear while using guided sessions.

6. Accounts

Some features may require an account. You are responsible for keeping your sign-in credentials secure and for all activity under your account. Notify us promptly if you believe your account has been compromised.

7. Subscriptions and billing

Sitria Premium is an auto-renewing subscription, weekly or yearly. Prices are shown before you buy.

App Store purchases are billed to your Apple Account and governed by Apple's terms. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Cancel any time in your Apple Account settings or in Sitria under Settings → Manage subscription.

In the United States you can also subscribe through our web checkout, run by RevenueCat with Stripe. Web subscriptions renew automatically until you cancel. Cancel any time from the link in your receipt email or in Sitria under Settings → Manage subscription.

When you cancel, access continues until the end of the period you've paid for. We may change prices or what's included in a plan with reasonable notice; a price change applies from your next renewal.

8. Acceptable use

You agree not to:

use the Service for any unlawful purpose or in violation of any applicable law;
attempt to interfere with, reverse engineer (except as permitted by law), or gain unauthorized access to the Service or its systems;
copy, modify, or create derivative works of the Service except as expressly permitted;
harass, abuse, or harm other users, or misrepresent health information to the Service;
use the Service while operating a vehicle or machinery, or in any way that could endanger you or others.

9. Intellectual property

The Service, including the Sitria name, logo, design, text, graphics, and software, is owned by ARKFLOW, INC. and protected by intellectual property laws. Subject to your compliance with these Terms, we grant you a limited, revocable, non-exclusive, non-transferable license to use the Service for its intended purpose. All rights not expressly granted are reserved.

10. Disclaimers

The Service is provided "as is" and "as available" without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that measurements such as depth or timing feedback will always be accurate. Use of the Service, including any exercise performed while using it, is at your own risk.

11. Limitation of liability

To the fullest extent permitted by law, ARKFLOW, INC. and its officers, directors, employees, and agents will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, data, or goodwill, arising out of or relating to your use of the Service. Our total liability for any claim relating to the Service is limited to the greater of (a) the amount you paid us for the Service in the twelve months before the claim, or (b) one hundred U.S. dollars ($100).

Nothing in these Terms limits liability that cannot be limited under applicable law, and nothing here excludes liability for death or personal injury caused by our negligence or for fraud.

12. Indemnification

You agree to indemnify and hold harmless ARKFLOW, INC. from any claims, damages, losses, and expenses (including reasonable attorneys' fees) arising from your use of the Service, your violation of these Terms, or your violation of any law or third-party right.

13. Termination

We may suspend or terminate your access to the Service at any time if you violate these Terms or if we discontinue the Service. You may stop using the Service at any time. Sections that by their nature should survive termination (including intellectual property, disclaimers, limitation of liability, and indemnification) will survive.

14. Changes to these terms

We may update these Terms from time to time. When we make material changes, we will post the updated Terms on this page and update the effective date. Continued use of the Service after changes take effect means you accept the revised Terms.

15. Governing law and disputes

These Terms are governed by the laws of the State of Delaware, USA, without regard to conflict-of-law rules. Except where prohibited by law, any dispute will be resolved in the state or federal courts located in Delaware, and you consent to their jurisdiction. If you live outside the United States, you may also have rights under the consumer laws of your country that these Terms cannot override.
