6. Licence and intellectual property
6.1 The Service, its software, design and content are protected by intellectual property law and belong to the Operator or its providers. For the duration of the Agreement, the User is granted a non-exclusive, non-transferable licence to use the Service for their own needs within the scope of the agreed Plan. The User is not entitled to reproduce, modify, decompile or provide the Service to third parties beyond the features of the Service.
6.2 User Content remains the property (or under the control) of the User. The User grants the Operator a limited authorization to process User Content solely for the purpose of providing the Service and to the extent necessary for its functioning.
7. Data from public registers, exchange rates, payment matching and other automated features
7.1 Some features of the Service use data from public registers (e.g. autofilling data based on the IČO), exchange rates, automatic matching of received payments based on the variable symbol and amount, sending e-mails and data exports. These data and operations originate from external sources or are carried out automatically.
7.2 The Operator is not responsible for the accuracy, completeness or currency of data from external sources (registers, exchange rates, banking data) or for the consequences of incorrect automatic matching of a payment or non-delivery of an e-mail. The User is obliged to check the automated outputs.
8. Availability of the Service, maintenance and changes
8.1 The Operator will make reasonable efforts to keep the Service available, but provides no guarantee of uninterrupted, error-free or secure availability and does not provide a guaranteed level of availability (SLA), unless separately agreed in writing.
8.2 The Operator is entitled to take the Service offline for the purpose of maintenance, updates and repairs, and is entitled to change, develop, restrict or discontinue the features of the Service to a reasonable extent. The Operator will inform the User of material changes to features with reasonable advance notice by e-mail or in the application. The provisions on necessary updates and on changes to digital content vis-à-vis the Consumer (§ 2389o and § 2389q of the Czech Civil Code) remain unaffected thereby.
9. Electronic Signature Feature for Contracts
9.1 The Electronic Signature Feature allows a document to be sent for signature and signed electronically; for each signature, the Service records a timestamp, a record of consent and control mechanisms (in particular a document hash using the SHA-256 method and a record of the process – an audit trail).
9.2 The User expressly acknowledges that:
(a) a signature created using this feature constitutes an electronic signature within the meaning of the eIDAS Regulation (Regulation (EU) No 910/2014), at the level of a simple or advanced electronic signature — NOT a qualified electronic signature;
(b) the Operator does not warrant that such a signature meets the form or requirements required by legal regulations for a specific legal act (e.g. a legal act requiring written form with an officially verified signature, a higher form, or a qualified signature); the assessment of the suitability and sufficiency of the chosen level of signature for the given purpose rests solely with the User;
(c) the Operator is not a party to the documents signed through the Electronic Signature Feature, is not responsible for their content, validity or enforceability, and provides no guarantee of the legal effect or evidentiary value of the signature;
(d) the audit trail, timestamps and control hashes are provided "as is" as a technical aid.
10. Limitation of liability
The provisions of this Article apply in relation to a Consumer only to the extent that they do not limit their statutory rights (see Article 11). In relation to an Entrepreneur, they apply in full.
10.1 The Service is provided "as is" and "as available". To the extent permitted by legal regulations, the Operator provides no warranties regarding the suitability of the Service for the User's specific purpose, its uninterrupted availability, error-free operation, or the correctness of automated outputs.

10.3 The aggregate amount of damages that the Operator is obliged to compensate to a User-Entrepreneur across all claims combined is, to the extent permitted by legal regulations, limited to the amount corresponding to the total of the payments that the User paid for the Service over the 12 months preceding the occurrence of the damage; for the free-of-charge "Free" Plan it is limited to the amount of 1 000 Kč. The parties declare that they consider this limitation, having regard to the nature and price of the Service, to be reasonable within the meaning of § 2898 of the Czech Civil Code.
10.4 This Article does not exclude or limit liability for damage caused to a person's natural rights, for damage caused intentionally or through gross negligence, or liability to the extent that legal regulations do not permit its exclusion or limitation (§ 2898 of the Czech Civil Code).
10.5 The User is responsible for making their own backups of User Content that is significant to them. The Operator is not liable for loss of data beyond Article 10.4.
11. Special provisions for Consumers
11.1 If the User is a Consumer, the special provisions on the supply of digital content to a consumer (§ 2389g et seq. of the Czech Civil Code) and the consumer protection provisions also apply to the relationship. No provision of these Terms shall be interpreted as limiting the statutory rights of the Consumer; any arrangements that would limit them shall not apply to the Consumer.
11.2 Rights arising from defective performance. The Consumer may notify a defect of the Service and exercise the rights arising from defective performance under § 2389i et seq. of the Czech Civil Code. Defects are claimed by e-mail at dankrul.krul@gmail.com. The Operator will remedy defects within a reasonable time, having regard to the nature of the Service.
11.3 Withdrawal from the contract. If the Agreement is concluded by distance means, the Consumer has the right to withdraw from the Agreement within 14 days without giving a reason (§ 1829 of the Czech Civil Code). The Consumer acknowledges that if they request that the provision of the Service begin before the expiry of this period and grant express consent thereto, having been informed of the loss of the right of withdrawal, the right of withdrawal lapses upon the supply of the digital content / full provision of the service (§ 1837 of the Czech Civil Code). A model notice and withdrawal form are available on request at the e-mail address stated above.
11.4 Out-of-court dispute resolution. The body competent for the out-of-court resolution of consumer disputes arising from the Agreement is the Česká obchodní inspekce (Czech Trade Inspection Authority) (Štěpánská 567/15, 120 00 Praha 2, www.coi.cz). The Consumer may also use the online dispute resolution (ODR) platform operated by the European Commission.
11.5 The Consumer's rights arising from liability for defects, to necessary updates and to information about changes to digital content (§ 2389o, § 2389q and § 2389s of the Czech Civil Code) remain preserved.
12. Duration and termination of the Agreement
12.1 The Agreement is concluded for an indefinite period, unless otherwise agreed.
12.2 The User may terminate the Agreement at any time by cancelling the subscription and/or the Account; a paid subscription runs until the end of the paid period and the unused portion is not refunded, unless otherwise provided in the Terms or by law.
12.3 The Operator may terminate the Agreement with a 14-day notice period; in the event of a material breach of the Terms by the User, it may terminate the Agreement with immediate effect.
12.4 After cancellation of the Account, the Operator will allow the User to export User Content within a reasonable period; after its expiry, the Operator is entitled to delete User Content, with the exception of data that it is obliged or entitled to retain under legal regulations (in particular tax documents).
13. Changes to the Terms
13.1 The Operator is entitled to unilaterally amend these Terms to a reasonable extent, in particular due to the development of the Service, changes in legal regulations or operational reasons. The Operator will inform the User of a change by e-mail or in the application at least 14 days before it takes effect.
13.2 If the User disagrees with a change, they are entitled to terminate the Agreement before the change takes effect. By continuing to use the Service after the change takes effect, the User agrees to the amended Terms. In relation to the Consumer, changes are governed by § 2389q of the Czech Civil Code.
14. Governing law and dispute resolution
14.1 The Agreement and these Terms are governed by the legal order of the Czech Republic, in particular by zákonem č. 89/2012 Sb., the Czech Civil Code. The choice of law must not deprive the Consumer of the protection afforded to them by the mandatory provisions of the law of the state of their habitual residence.
14.2 The courts of the Czech Republic are competent to resolve disputes; if the User is an Entrepreneur, the locally competent court is the general court according to the Operator's registered office, to the extent permitted by legal regulations.
15. Final provisions
15.1 If any provision of the Terms is or becomes invalid, ineffective or unenforceable, this does not affect the validity of the remaining provisions; in place of the defective provision, a provision whose meaning most closely approximates that of the defective one shall apply.
