Terms of Service

These Terms of Service ("Terms") govern your use of the ProovX Service provided by NETBULLS Sp. z o.o., a company registered in Poland ("ProovX", "we", "us", or "our"). ProovX is a product of NETBULLS Sp. z o.o.

Please read these Terms alongside our Privacy Policy, which explains how we handle your personal data.

1. Who we are & acceptance

The ProovX Service is operated by NETBULLS Sp. z o.o. (company details at the end of this document).

By creating an account, signing in, or otherwise using the Service, you agree to these Terms. If you do not agree to them, please do not use the Service.

If you use the Service on behalf of a club or organisation, you confirm that you are authorised to accept these Terms for that organisation.

2. The Service

ProovX is a platform for sports clubs and organisations and their members. Depending on what your club uses, the Service may include:

• Memberships and member management;
• Events and training sessions, including scheduling and attendance;
• Gradings, achievements, and progress records;
• Messaging and notifications;
• Club websites designed, built, and hosted by ProovX;
• A person-owned record of achievements that stays with you across clubs.

The Service is available through the ProovX mobile application (including the ProovX Dev build) and the ProovX web application.

3. Accounts & eligibility

To use most features you need an account. You can sign in using your phone number, a passkey, or a linked social account. You agree to provide accurate information and to keep it up to date.

You are responsible for keeping your sign-in credentials and devices secure, and for activity that happens under your account. Please tell us promptly if you believe your account has been used without your permission.

Where required by law, a parent or legal guardian must consent to a minor's use of the Service. A child uses ProovX only through a parent- or guardian-managed arrangement, typically via their club. Where the law requires consent for a person under 16 (the age that applies in Poland under the GDPR), the parent or legal guardian gives that consent. See our Privacy Policy for how we handle children's data.

4. Clubs & organisations

Clubs and organisations that use ProovX are independent from us. A club decides who its members are and manages its own club data, including memberships, events, gradings, and communications with its members.

A club may set its own enrollment terms, which apply between you and the club. We are not a party to the arrangements between you and a club, and we are not responsible for a club's decisions, policies, or conduct.

5. Your content

You keep ownership of the content you provide to the Service. You grant us a limited licence to host, store, process, and display that content solely to operate and provide the Service to you and, where relevant, to your club.

You are responsible for the content you post and for making sure you have the right to share it. We may remove content that violates these Terms or applicable law.

6. Acceptable use

When using the Service, you agree not to:

• Use the Service for any unlawful, abusive, or infringing purpose;
• Interfere with or circumvent security, attestation, or rate-limiting measures;
• Scrape, harvest, or bulk-extract data from the Service;
• Impersonate any person or organisation, or misrepresent your affiliation;
• Disrupt the Service or attempt to gain unauthorised access to it or its systems.

7. Communications

As part of providing the Service, we send you transactional messages such as verification codes and account or security notices. These are part of the Service, not marketing.

Sign-in codes are sent on WhatsApp if your number can receive them, otherwise by SMS; the first code to a new number goes by SMS, and you can switch WhatsApp off at any time in Settings › Account or ask for an SMS code instead. Account and security notices may be sent by SMS, WhatsApp, or email. Your carrier's message and data charges may apply. How we handle your phone number for this is described in our Privacy Policy.

8. Payments

If a club offers paid items through the Service, the price and terms are shown to you at the point of purchase. Payments are processed by our payment provider (Stripe Payments Europe, Ltd.); your card details are entered directly with the provider and are never stored by us.

Refunds are handled according to the club's stated terms and any applicable consumer-protection law.

9. Our intellectual property

The ProovX name, symbol, and software, and all related intellectual property, belong to us or our licensors. These Terms do not grant you any right to use our branding except as needed to use the Service. You may not reverse engineer, decompile, or disassemble the software, except to the extent this restriction is prohibited by applicable law.

10. Availability & changes

We work to keep the Service available and reliable, but we may change, suspend, or discontinue features from time to time. For material changes we will give reasonable notice where practicable. Beta and Dev builds are provided for evaluation and may be unstable, incomplete, or reset without notice.

11. Termination

You can stop using the Service at any time and may delete your account. We may suspend or terminate your access if you breach these Terms or use the Service in a way that could harm other users, a club, or us.

What happens to your data after termination is described in our Privacy Policy.

12. Disclaimers & liability

To the extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind. Nothing in these Terms excludes or limits any liability that cannot be excluded or limited under applicable law, including liability for death or personal injury caused by negligence, or for fraud.

If you are a consumer, your statutory rights under the laws of Poland and the European Union are not affected by these Terms.

13. Governing law & disputes

These Terms are governed by the laws of Poland. If you are a consumer resident in the European Union, you also keep the protection of any mandatory provisions of the law of your country of residence.

Disputes will be subject to the courts of Poland, unless mandatory law gives you the right to bring proceedings elsewhere. The European Commission also provides an online dispute resolution platform for consumers at ec.europa.eu/consumers/odr.

14. Changes to these Terms

We may update these Terms from time to time — for example, to reflect changes in the law, to keep the Service secure, to cover new or changed features, or to make the Terms clearer. We will post the updated version on this page and revise the "Last updated" date at the top.

For material changes, we will give you at least 14 days' advance notice in the app or by email. You can stop using the Service and delete your account before the changes take effect; if you continue to use the Service after that, the updated Terms apply.

15. Technical requirements, content & complaints

To use the ProovX app you need a device running a current version of iOS or Android; to use the web app you need a current web browser and an internet connection.

You must not supply or transmit unlawful content through the Service.

If something goes wrong, you can make a complaint by writing to hello@proovx.com. We will consider it and reply within 14 days.
