Terms of service

These Terms govern your use of ustukalsin.pl and the conditions of joining the Üstü Kalsın beta waitlist during the pre-launch period.

§ 1. Definitions

• Operator — Team Knocknock Sp. z o.o., registered at ul. Rekreacyjna 29B/2, 05-500 Józefosław, woj. mazowieckie, Polska, NIP PL1182194995.
• Site — the website at ustukalsin.pl, including all sub-pages.
• Üstü Kalsın — the project of a micro-saving application that rounds up card transactions into crypto-assets, developed by the Operator.
• Beta — the pre-launch phase in which selected Users receive early access to the app.
• User — any natural person using the Site.

§ 2. Nature of the Site

The Site currently performs an informational and marketing function only. The Üstü Kalsın application is under development and is not yet provided as a service. Materials on the Site do not constitute an offer within the meaning of Polish civil law, nor investment, financial, legal or tax advice.

§ 3. Beta waitlist signup

1. Signup is done via the form on the /en/beta subpage.
2. Signup requires providing an email address and giving consent to data processing for launch communications.
3. Signup does not create any contractual relationship between the User and the Operator beyond voluntary receipt of email notifications.
4. The User may withdraw consent at any time and be removed from the list by writing to contact@teamknocknock.com.
5. The Operator does not guarantee that every signed-up User will receive beta access — the first cohort is limited to 500 people, in order of signup.

§ 4. Crypto-asset risk

After launch Üstü Kalsın will enable the purchase of crypto-assets (incl. BTC, ETH, USDC). Investing in crypto-assets carries high risk, including the risk of losing the entire amount invested. The value of crypto-assets is highly volatile and depends on market, technological, regulatory and macroeconomic factors beyond the Operator's control.

The Operator does not promise any profit or capital protection. Decisions to purchase crypto-assets are made by the User independently and at their own risk.

Crypto-asset services in the EU are regulated by Regulation (EU) 2023/1114 (MiCA). After launch the Operator will operate through a licensed CASP entity passported into Poland under Article 65 MiCA. Details on the Trust page.

§ 5. Technical requirements

Use of the Site requires a modern browser (Chrome, Firefox, Safari, Edge) with JavaScript enabled and an active internet connection.

§ 6. Intellectual property

All content, graphics, site layout and the name "Üstü Kalsın" are the property of the Operator or are used under appropriate licences. Copying or commercial use without the Operator's consent is prohibited.

§ 7. Liability

The Operator endeavours to keep the Site continuously available and error-free but does not guarantee the absence of technical interruptions. The Operator is not liable for damages arising from temporary unavailability, force majeure, or investment decisions made by the User based on general information published on the Site.

§ 8. Complaints

Comments regarding the Site can be sent to contact@teamknocknock.com. We respond within 14 business days.

§ 9. Final provisions

2. Disputes arising from these Terms are settled by the court having jurisdiction over the Operator's registered office, subject to consumer-protection provisions.
3. The Operator reserves the right to amend these Terms. Material changes will be communicated to waitlist members with 14 days' notice.
4. These Terms enter into force on the date of publication.
