Terms and conditions

These terms and conditions set out the rules for buying and using Mitilena hardware carriers. Please read them carefully. We build tools for absolute control over your assets, and that means one hundred percent personal responsibility on your side.

1. Subject of the contract

The Seller supplies and the Buyer purchases physical NFC carriers (cards, stickers, tags) intended for storing encrypted data locally. The Seller (Mitilena) is not a custodian, an exchange or a financial intermediary, and provides no services for holding, transferring or managing cryptocurrency assets.

2. Conclusion of the contract, payment and delivery

By submitting an order on mitilena-store.com and paying for it, the Buyer expresses agreement with these terms and conditions, and the purchase contract is thereby concluded. Prices of goods are stated on the website and are valid at the moment the order is created. Payment methods are listed in the basket.

Delivery is handled by the carriers listed on the website. Title to the goods and the risk of damage to them pass to the Buyer at the moment the Buyer physically takes receipt of them.

3. Zero knowledge architecture

The key condition of this contract: all carriers are supplied in an uninitialized (completely empty) state. All cryptography, including the generation of private keys, encryption and the signing of transactions, takes place exclusively and locally on the Buyer’s own device.

The Seller has no access to the Buyer’s keys, keeps no backups, and has no technical means of restoring access to the data should the password or the carrier be lost.

4. The Buyer’s responsibility

By making a purchase the Buyer confirms awareness of the risks associated with self-custody of crypto assets, and assumes full responsibility for:

Safekeeping of the decryption password: Loss of the password set by the Buyer leads to irreversible lockout of the data on the carrier. Our support cannot help you in such a case.
Creating backups: The Buyer undertakes to arrange redundancy independently (to create physical copies of the keys on further carriers) as protection against loss of or damage to the main carrier.
Security of the environment: The Buyer is responsible for the security of the smartphone or PC used to interact with the carrier.

5. Exclusion of warranties and limitation of liability

The Seller provides the accompanying software as a dependable interface for working with decentralized networks. We improve our algorithms continuously and release updates regularly in order to maintain the highest security standards.

The software is nevertheless provided “as is” (AS IS). The Seller is not liable for temporary unavailability of functionality, nor for damage arising as a result of:

Force majeure, changes in operating system policies (iOS/Android) or blocking by application stores.
Overload, hard forks or outages of the decentralized blockchain networks themselves.
Use of the application on modified devices (jailbreak / root).
Loss of the password by the Buyer, physical damage to the carriers, or compromise of the smartphone by malicious software.

Financial limit: To the maximum extent permitted by law, the Seller’s aggregate liability towards the Buyer cannot exceed the amount the Buyer actually paid for the physical carrier purchased.

6. Returns and withdrawal from the contract

Return or exchange of carriers in undamaged condition (within the 14 day period) is possible only up to the moment the device is initialized (encrypted data written to it), and provided the packaging and appearance of the goods remain intact.

Once initialized, the carriers are goods adjusted to the individual requirements of the consumer, usable exclusively by the person who purchased them, because of the cryptographic binding of the data stored on them. In accordance with Section 1837(d) of the Civil Code, withdrawal from the contract is not possible for such goods.

7. Complaints procedure

This complaints procedure is based on the relevant provisions of Act No. 89/2012 Coll., the Civil Code, and Act No. 634/1992 Coll., on Consumer Protection.

Warranty period. A consumer Buyer is entitled to exercise rights arising from a defect occurring in consumer goods within 24 months of receipt. The warranty period begins to run at the moment the Buyer takes receipt of the goods.

The warranty does not cover:

defects arising from ordinary wear and tear,
mechanical damage caused by improper use or handling contrary to the instructions,
damage caused by unauthorized interference with the hardware or by an attempt to modify the carrier,
damage caused by force majeure (flooding, fire, lightning strike and the like),
given the nature of the goods, the warranty does not cover loss of the decryption password set by the Buyer, nor the impossibility of restoring access to data stored on the carrier (see Sections 3 and 4 of these terms).

Making a complaint. The Buyer makes a complaint to the Seller without undue delay after discovering the defect, either:

by e-mail to support@mitilena.com,
or by post to the Seller’s registered address given in Section 11.

In the complaint the Buyer states: identification and contact details, the order or tax document number, a description of the defect complained of and how it manifests itself, and the requested method of settlement. We also recommend sending photographic documentation of the defect.

Settlement of a complaint. The Seller decides on a complaint immediately, or within 3 working days in complex cases. The complaint, including remedy of the defect, must be settled without undue delay and within 30 days at the latest from the date it was made, unless the Seller and the Buyer agree on a longer period. The Buyer is informed of the outcome by e-mail to the address given in the order.

Rights arising from defective performance. If the defect can be remedied, the Buyer has the right to have it remedied free of charge, or to the delivery of a new item free of defects. If that is not possible or is disproportionate, the Buyer has the right to a reasonable discount from the purchase price, or may withdraw from the contract. If the defect cannot be remedied and prevents proper use of the item as an item free of defects, the Buyer has the right to delivery of a new item, to a reasonable discount, or to withdrawal from the contract.

8. Protection of personal data

By creating an order the Buyer acknowledges that their personal data (first name and surname, telephone number, e-mail address, delivery address) will be processed in accordance with EU Regulation 2016/679 (GDPR). Processing takes place solely on the basis of necessity for the performance of this contract and the delivery of the goods. The Seller does not collect or process, and has no access to, the Buyer’s cryptographic data.

9. Contacting the Seller and dispute resolution

The Buyer sends all enquiries, complaints, requests and other communications to the e-mail address: support@mitilena.com.

These terms and conditions are governed by the law of the Czech Republic. We seek to resolve any disputes primarily by agreement. The body competent for the out-of-court resolution of consumer disputes arising from the purchase contract is the Czech Trade Inspection Authority, with its registered office at Štěpánská 567/15, 120 00 Prague 2, company number 000 20 869, website: https://adr.coi.cz. The online dispute resolution platform is available at https://ec.europa.eu/consumers/odr.

10. Validity and changes

These terms and conditions apply from the moment they are published on mitilena-store.com. The Seller has the right to change the wording of the terms and conditions by publishing a new version. For contracts concluded earlier, the terms in force at the moment the order was submitted always apply.
