HodlerKit Terms of Sale
Version 1.0.0 — effective 19 July 2026
1. Parties
The seller is Sinfin s.r.o., company ID 45800171, VAT ID CZ45800171, registered office Korunní 2569/108, Vinohrady, 101 00 Prague 10, Czech Republic, registered in the Commercial Register maintained by the Municipal Court in Prague. Contact: [email protected]. Under these terms, the buyer must be a consumer habitually resident in the Czech Republic.
2. Product
HodlerKit is locally operated software for testing and using rule-based trend-following strategies with the buyer’s own account. The selected edition, main features, compatibility, price and update period are shown in the offer before the order is submitted.
The licence includes perpetual use of the purchased major version on no more than two active installations and updates to that version for 12 months. This period does not restrict security or corrective updates required by mandatory consumer law.
HodlerKit does not hold the buyer’s assets, provide personalised investment advice or promise a return. The buyer chooses the configuration and whether to run a strategy, and bears market risk.
3. Price, order and payment
Checkout displays the final VAT-inclusive price, taxable amount and VAT. Payment is made in bitcoin on-chain or over Lightning through BTCPay Server. The BTC amount and exchange rate remain valid for the period shown by the payment page.
Before submitting, the buyer can review the edition, price, country, email and all acknowledgements. The button clearly states that the order entails an obligation to pay. Submitting checkout places a binding order. The contract is concluded when settlement is confirmed and the digital content is made available at the same time. If settlement cannot be reconciled exactly, the order enters manual review and content is not automatically released.
4. Delivery and recovery
After final settlement, the seller makes the installer, receipt and licence claim available without undue delay. Before payment redirect, the buyer receives a unique recovery value and must store it securely. The seller keeps only a one-way digest and cannot reveal the original. An optional email is only a delivery channel; without the recovery value it does not replace proof of entitlement.
5. Compatibility and cooperation
Supported operating systems, Docker, exchange, spot pairs and minimum versions are listed with the offer and in documentation. The buyer is responsible for secure device, account and API-key configuration, including disabled withdrawals. API keys are not sent to the seller or HodlerKit cloud.
The buyer must install available security updates and provide reasonable cooperation when a defect is investigated. Changes to third-party APIs, rules or availability may affect the software; the seller provides necessary updates to the extent required by law and the agreed support.
6. Conformity and complaints
The digital content must match its description, agreed purpose, compatibility and update commitments. Report a defect to [email protected] with the order number and a description. The seller confirms receipt and resolves consumer complaints within the statutory period. Depending on the defect, the consumer may request remedy, a proportionate price reduction, or termination and reimbursement. Statutory rights cannot be restricted by the licence, risk acknowledgement or refund policy.
7. Withdrawal and voluntary refund
The buyer may request supply before the 14-day withdrawal period expires. If the buyer also expressly acknowledges that the right to withdraw is lost once the digital content is fully made available, the right no longer applies after delivery. Without both separate confirmations, it remains available. Details and the voluntary refund are in the Refund Policy accepted at checkout.
8. Liability and availability
The seller is not liable for market loss caused by the buyer’s decision or an uncontrollable third-party outage or change. This does not limit liability for non-conforming content, intent, gross negligence, personal injury or any consumer right that cannot be excluded.
9. Personal data
Purposes, data categories, retention, recipients and rights are described in the Privacy Notice shown before ordering. Checkout asks for no marketing consent and email is optional.
10. Law and disputes
Czech law applies without depriving a consumer of mandatory protection. Contact [email protected] first. The competent Czech alternative dispute resolution entity is the Czech Trade Inspection Authority, Central Inspectorate — ADR Department, Gorazdova 1969/24, 120 00 Prague 2, https://coi.gov.cz/informace-o-adr/.
