The provisions of the General Terms shall also apply to all offers, pro forma invoices, preliminary contracts, legal and business declarations, and other services arising from the business relationship between the Company and the Customer.

These General Terms form an integral part of the contracts concluded between the Customer and the Company. By signing the contract or by otherwise entering into a contractual relationship, the purchaser fully agrees to the content of these General Terms and confirms that they are fully familiar with their content.

The submission of a valid order in the Company’s online store shall be deemed to constitute the signing of a contract, and the purchaser must agree to these General Terms prior to submitting the order.

These General Terms shall bind the consumer only if the consumer was expressly informed of their existence prior to the conclusion of the contract, pro forma invoice, preliminary contract, or offer.

Use of terms:

A Customer is any purchaser who is a natural person and who is in a legal and business relationship with the Company, regardless of their legal or status form.

A Consumer is any Customer or purchaser who is a natural person and who acquires or uses the Company’s goods or services for personal purposes or for purposes outside their professional or income-generating activity.

An Offer is a unified term for an offer in various forms, such as a pro forma invoice or other forms of proposal for concluding a contract, which the Company provides to the Customer.

A Contract is an agreement in written form concluded between the Company and the Customer. A contract shall also be deemed concluded by an offer or pro forma invoice sent by the Company to the purchaser and accepted or confirmed by the purchaser. These General Terms form an integral part of every contract.

The Subject of the Contract may be goods and services in accordance with the Company’s sales catalogue.

The term “you” refers to the user, purchaser, or customer.

The Customer shall be deemed to be acquainted with the amendments at the moment the amendment is published on the website and upon confirmation of the submission of an order. By this, the Customer shall be deemed to agree to the amendment of the General Terms and Conditions.

The Company and the Customer may exclude the application of individual provisions of these General Terms and Conditions if such provisions are not consistent with the provisions of the contract or with the general purpose of the contract.

5. Pseudonymized Method of Purchase and Purchase with Cryptocurrency – Limitations and Exclusion of Warranty

The purchase is possible without the disclosure of personal data. The Customer may make payment using the cryptocurrency Monero (XMR). Upon successful payment, the Customer receives a confirmation order ID. After placing the order, the Customer receives a payment address and the amount in XMR or another cryptocurrency. The order is confirmed upon receipt of the required amount. A purchase by a Customer who is a pseudonymized Customer is carried out exclusively with advance payment of the full purchase amount, which applies both to the initial purchase and to the extension of the subscription for 12 months.

The product is sent by post or delivered digitally. The Customer must provide a delivery address when placing the order. A pickup point or personal delivery by agreement is also possible.

Castrum OS and customized phones are developed for secure use. Due to the anonymous nature of the purchase, we do not provide a classic warranty or ownership identification.

In the event of technical issues, we provide anonymous support via the e-mail system or another method of communication.

The Company does not collect or store any personal data of the Customer, except for those voluntarily provided. Transaction data is stored only in the internal system as a cryptographic identifier (hash).

In accordance with anti-money laundering (AML) legislation, the purchase of a device without customer identification is permitted only for payments with a value lower than EUR 10,000. For all transactions exceeding EUR 10,000 carried out with cryptocurrencies, the Company is obliged to identify the Customer in accordance with ZPPDFT-2. Anonymous purchase is not possible.

For all higher amounts, customer identification is required. In the case of an anonymous purchase above the statutory threshold, the Provider reserves the right to refuse warranty claims.

The Customer expressly confirms that they are aware that, in the case of an anonymous purchase exceeding EUR 10,000, in accordance with anti-money laundering legislation, the Provider requires customer identification, otherwise the Provider reserves the right to reject the order.

In the event that the Customer wishes to purchase a device with Castrum OS under an anonymous or pseudonymized name and without disclosure of personal data, the Customer agrees and confirms that they understand the following limitations:

the Company will obtain data from the Customer in the event of exercising a warranty or claiming a material defect for the physical device, for the purpose of proving ownership of the device and for the purpose of demonstrating that the Customer is a natural person exercising rights under the Consumer Protection Act,
in the event that the Customer is a legal entity, a pseudonymized purchase of a mobile device with Castrum OS is not possible if the purchase is made on behalf of a company where the company’s tax number is stated on the invoice,
for cryptocurrencies above a certain threshold, the need for KYC procedures may be triggered,
by making a pseudonymized purchase, the Customer agrees to the possibility that, in the event of failure to carry out customer identification, the warranty may be limited or excluded, however the Customer will have access to open support provided by the Company,

8. Digital License

Prior to placing an order, the Customer is obliged to familiarize themselves with the subject of the offer, the scope of services, the price, and these General Terms and Conditions.

An order shall be deemed valid and binding at the moment when the Customer:

confirms the order in a manner that clearly demonstrates their intent to purchase, or

Although cash payments by natural persons are permitted up to EUR 15,000, identification of the Customer is mandatory for amounts exceeding EUR 10,000 due to the provisions of ZPPDFT-2.

In the event that the Customer wishes to carry out a pseudonymized purchase exceeding EUR 10,000 without identification, the Company reserves the right to refuse the transaction, as such a sale would be contrary to anti-money laundering legislation.

13. Warranty

The warranty for the physical device is provided by the manufacturer of the Google Pixel phone and amounts to 24 months.

Phones purchased from the Company are preloaded with the security-oriented operating system Castrum OS, which replaces the factory Android system. As a result, the official manufacturer’s warranty (Google) may be void, and certain Google services or applications that require the original Android system may not be usable.

Nevertheless, each purchased phone includes a limited Company warranty, valid for 12 months for hardware defects (e.g. failure of the motherboard, display, battery), provided that the defect is not the result of physical damage, liquid ingress, or unauthorized intervention.

The warranty does not include software support for third-party software or applications that are not part of Castrum OS.

The warranty may be claimed using the following information:

date of receipt of the device,
order number or transaction hash (in the case of an anonymous purchase),
phone serial number or IMEI.

The Company provides support anonymously – via encrypted channels, without the need for personal identification.

The warranty is non-transferable and does not apply to products that have been resold, opened, physically damaged, or software-modified after receipt.

14. Liability for Material Defects and the Right to Withdraw from the Contract Without Stating Reasons

The Company is liable for material defects of Castrum OS. The Customer may exercise their rights arising from a material defect if they notify the seller of the defect within 2 (two) months from the day on which the defect was discovered. In the notification of the defect, the Customer must describe the defect in more detail and allow the seller to inspect the product. The Customer may notify the Company of the defect personally via the e-mail address. The Company shall issue the Customer with a confirmation of the assertion of a material defect.

The Company shall not be liable for material defects of the goods that become apparent after 2 (two) years have elapsed from the date the product was delivered to the Customer.

The Customer may require the Company to restore conformity of the goods free of charge within a period not exceeding 30 days. The Company may, after prior notification to the Customer, extend this period by 15 days.

In the event of non-conformity of the goods, the Company shall repair the goods or restore their conformity, or replace the goods with new ones, if such replacement is possible and does not involve disproportionately high costs for the Company.

In the event of return of goods due to non-conformity, the Customer shall first have the right to free repair or replacement of the goods in accordance with the previous paragraph of this Article, and only thereafter the right to withdraw from the contract or to a reduction of the purchase price in proportion to the non-conformity of the goods.

The Customer may withdraw from the contract whenever a defect becomes apparent within 30 days from the delivery of the goods.

It shall be deemed that the defect existed at the time of delivery if it appears within 6 (six) months from delivery. The Customer’s rights shall expire when 2 (two) years have elapsed from the day on which the seller was notified of the material defect.

A Customer who purchased goods at a distance has the right, within 14 days from receipt/collection of the goods (cooling-off period), to notify the Company (at the contact e-mail address: info@castrumlabs.xyz) that they withdraw from the contract, without having to state the reason for their decision. The withdrawal form is attached to these Terms at the end of the text.

In accordance with ZVPot-1, the Consumer has the right to withdraw in the case of a distance purchase, except with regard to digital content if the service has already been activated (e.g. OS registered).

The withdrawal option referred to in the previous point does not apply to products that are made to order and according to the Customer’s specific requirements.

The cost of returning the goods in the event of withdrawal shall be borne by the Customer.

The goods must be returned to the Company no later than 14 days from the submission of the notice of withdrawal from the contract; the seller may withhold the refund of payments received for the goods until receipt and inspection of the returned goods or until the Consumer provides proof that the goods have been returned or physically returns the goods to the Company’s business address. The Consumer shall return the received goods or hand them over to the company or a person authorized by the company to accept the goods.

Postage costs shall not be refunded in the event of return of the goods and shall be borne by the Customer. The Customer is also obliged to pay the postage costs for returning the goods.

The received goods must be returned by the Customer undamaged, in unchanged quantity, and in undamaged original packaging.

The Customer shall be liable for any diminished value of the goods if the diminution in value results from handling that is not necessary to establish the nature, characteristics, and functioning of the goods.

If a promotional discount code was used when placing the order, the Consumer shall be refunded the value of the goods with the discount applied upon withdrawal from the contract.

The refund of the purchase price shall be made as soon as possible, but no later than 15 days from receipt of the goods. The purchase price shall be refunded to the Customer’s transaction account specified by the Customer in the withdrawal form.

The Customer may withdraw from a contract for the supply of digital content or a digital service if a change to the digital content or digital service has a negative effect on the Consumer’s access to or use of the digital content or digital service, unless such negative effect is insignificant. In this case, the Consumer is entitled to withdraw from the contract for the supply of digital content or digital service free of charge within 30 days from receipt of the notification of the change to the digital content or digital service or from the moment the company changes the digital content or digital service, whichever occurs later.

Notwithstanding the previous paragraph, the Customer shall not have the right to withdraw from the contract for the supply of digital content or digital service if the company has enabled the Consumer to retain the unchanged digital content or digital service at no additional cost and conformity of such digital content or digital service is ensured.

In accordance with Article 135 of ZVPot-1, the Customer shall not have the right to withdraw from the contract for digital content once the digital content is activated or Castrum OS begins to be used. By concluding the contract, the Customer expressly agrees that upon commencement of the provision of digital content (including activation of Castrum OS and digital services), they waive the right to withdraw from the contract.
