Terms of Service

Last updated: September 22, 2026

These Terms of Service ("Terms") govern your access to and use of JustX (the "Service"), operated by Darii Velychko ("JustX," "we," "us," or "our"), based in Germany. By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Eligibility

You must be at least 18 years old (or the age of legal majority in your jurisdiction) to use JustX. By using the Service, you confirm you meet this requirement.

2. What JustX Does

JustX is an AI-powered personal assistant that helps you plan and complete everyday tasks, such as web searches, price comparisons, availability checks, meeting scheduling, and — only where you give explicit confirmation — placing bookings or orders with third parties on your behalf (an "Action").

Important: JustX will never submit a final booking, order, or payment on a third-party website without your explicit, step-specific confirmation. Low- and medium-risk steps (such as searching or comparing options) may run automatically; any step JustX classifies as high-risk (such as finalizing a purchase or reservation) requires your confirmation before it is executed.

3. Accounts

You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account. Notify us immediately if you suspect unauthorized use of your account.

4. Free and Paid Plans

JustX currently offers a free tier. We may introduce paid subscription plans with additional features or usage limits. If you subscribe to a paid plan:

  • Payments are processed by Stripe; by subscribing, you also agree to Stripe's applicable terms.
  • Subscriptions renew automatically at the end of each billing period unless canceled beforehand.
  • You can cancel at any time from Settings; cancellation takes effect at the end of the current billing period, and we do not provide partial refunds for unused time unless required by applicable law.
  • We may change pricing with reasonable advance notice; continued use after a price change takes effect constitutes acceptance of the new price.

5. AI-Generated Content and Actions

JustX uses third-party AI models to interpret your requests, plan tasks, and generate responses. You acknowledge that:

  • AI-generated responses, plans, and summaries may contain errors or inaccuracies;
  • You are responsible for reviewing any information, plan, or draft booking/order details before confirming a high-risk Action;
  • JustX acts on your behalf only to the extent you explicitly confirm — you remain responsible for the substance of any booking, order, or communication ultimately submitted using your confirmation;
  • JustX is a tool to assist you, not a substitute for your own judgment, especially for decisions involving money, health, legal, or safety-critical matters.

6. Third-Party Services and Websites

Completing an Action may involve JustX interacting with third-party websites or services (e.g., a restaurant booking platform, a delivery platform, or your Google Calendar/Gmail account) on your behalf, using data you've provided or connected. We are not responsible for the availability, accuracy, pricing, or conduct of these third-party services. Any contract formed as a result of a booking or order (e.g., with a restaurant or delivery platform) is between you and that third party, not with JustX.

7. Acceptable Use

You agree not to:

  • Use JustX for any unlawful purpose, or to attempt to place fraudulent orders or bookings;
  • Attempt to circumvent JustX's confirmation flow for high-risk Actions;
  • Interfere with or disrupt the Service, including by attempting to reverse-engineer, scrape, or overload it;
  • Use JustX to harass, defraud, or impersonate any person or business;
  • Upload content that is illegal, infringing, or harmful to third parties.

We may suspend or terminate accounts that violate these Terms.

8. Connected Accounts (Google Calendar / Gmail)

If you connect your Google Calendar and/or Gmail account, you authorize JustX to access the specific data described in our Privacy Policy (calendar events, and read-only access to booking-related email threads) to provide the Service. You can disconnect these integrations at any time in Settings.

9. Intellectual Property

JustX and its original content, features, and functionality are owned by us and protected by applicable intellectual property laws. You retain ownership of the content you submit (messages, attachments), but grant us a limited license to process it as necessary to provide the Service.

10. Disclaimers

The Service is provided "as is" and "as available," without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not guarantee that the Service will be uninterrupted, error-free, or that any booking, order, or task will be completed successfully.

11. Limitation of Liability

To the maximum extent permitted by applicable law, JustX shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, arising out of or in connection with your use of the Service — including losses arising from an inaccurate AI-generated response, a failed or incorrect booking/order, or a third-party service's conduct. This limitation does not apply to liability arising from intent, gross negligence, or injury to life, body, or health, or other liability that cannot be limited under applicable law (including the German Product Liability Act, Produkthaftungsgesetz).

12. Termination

You may stop using the Service and delete your account at any time from Settings. We may suspend or terminate your access if you violate these Terms, or discontinue the Service (or parts of it) with reasonable notice where practicable.

13. Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will notify you (e.g., via email or an in-app notice) before the changes take effect. Continued use of the Service after changes take effect constitutes acceptance of the updated Terms.

14. Governing Law and Disputes

These Terms are governed by the laws of Germany, without regard to conflict-of-law principles. If you are a consumer, you retain any mandatory consumer-protection rights available under the law of your country of residence. The European Commission's Online Dispute Resolution platform is available at https://ec.europa.eu/consumers/odr.
