  • Activation means the technical process of verifying a license, for example by entering a license key, downloading a local license file or verifying the license through a license server.

3. Product information

A description of the main features of the Product is provided on the product page or within the ordering interface. The Product description may include in particular:

  • the intended platform and supported versions,
  • the main functions and permitted use,
  • technical requirements,
  • information on functionality, compatibility and interoperability,
  • information on technical protection measures,
  • whether the Product requires activation or other technical steps,
  • the scope of support and updates,
  • licensing limitations.

The Buyer acknowledges that the Product may require a specific platform version, hosting setup, PHP version, database, server configuration, access permissions or other technical prerequisites stated in the Product description.

4. Order and conclusion of the contract

The Buyer orders the Product through an order form, customer account, e-mail communication or any other interface used by the Seller to accept orders.

Before submitting the order, the Buyer has the opportunity to review the entered data and correct any errors. The content of the contract, these business terms and conditions and the applicable license terms are available to the Buyer before the order is submitted, and the Buyer may review, save or print them.

If the order is placed electronically, the Seller will provide before completion of the order at least information about the technical steps leading to the conclusion of the contract, the options for identifying and correcting input errors before the order is sent, the languages in which the contract may be concluded, and whether the contract will be stored after conclusion and whether the Buyer will be granted access to it.

By submitting the order, the Buyer confirms that they have read these business terms and conditions and the license terms applicable to the relevant Product. If the order is completed by using an order button or a similar control, that control must be labelled with clear wording expressing a payment obligation.

The contract is concluded at the moment when the Seller accepts the order and confirms that fact to the Buyer, typically by a confirmation e-mail or another text message.

The concluded contract is archived by the Seller in electronic form. Upon request, it may be made available to the Buyer to a reasonable extent unless prevented by legal or technical reasons. The contract is concluded in the Czech language unless the parties expressly agree otherwise.

5. Price and payment terms

Product prices are listed on the Seller's web interface. The final price payable by the Buyer is always displayed in the order summary before the order is completed.

The Buyer must pay the price using the selected payment method stated in the order. Unless expressly stated otherwise for a specific Product, the Seller is not obliged to deliver the Product before the price has been paid in full.

In the event of an obvious technical error in the displayed price, the Seller is not obliged to deliver the Product at such an obviously incorrect price. If the Buyer has already paid the wrong price, the Seller will refund the received payment without undue delay.

6. Product delivery

The Product is delivered electronically, in particular by:

  • sending a download link,
  • making the Product available in a customer account,
  • sending a license key,
  • sending or making available a local license file,
  • making documentation or updates available.

Unless stated otherwise for a specific Product, the Seller will deliver the Product without undue delay after receiving the payment.

The Product is deemed delivered when the Seller enables the Buyer to access the download, the license key, the Product activation or any other means of making the digital content available. The Seller may prove such availability in particular by a record of a sent e-mail, by making the content available in the customer account or by a technical system log.

7. Consent to immediate performance and withdrawal from the contract

If the Buyer is a Consumer and the subject matter of the contract is digital content supplied other than on a tangible medium, the Consumer will generally have the right to withdraw from the contract within 14 days from its conclusion unless the applicable law provides otherwise.

However, for Products the Seller normally offers supply without undue delay after payment. In such a case, before completing the order the Consumer may be asked to:

  • expressly consent to performance starting before the withdrawal period expires, and
  • acknowledge that, once performance has started under the conditions required by law, the right to withdraw from the contract is lost.

If such consent has been validly granted, the Consumer has been informed about the consequence, the Seller has provided the required confirmation in text form, and delivery of the Product has then started, the Consumer's right to withdraw from the contract ends to the extent permitted by law.

If the right of withdrawal has not been lost, or if the law grants a right of withdrawal in another case, the Consumer may exercise withdrawal by e-mail to the Seller or by any other unequivocal statement. The Seller will confirm receipt of the withdrawal without undue delay in text form if required by law.

In the event of a valid withdrawal from the contract, the Seller will refund the received payment without undue delay, no later than within the time limit required by law, using the same payment method unless another arrangement is agreed with the Buyer.

8. Functionality, compatibility, interoperability and updates

Before the contract is concluded, or no later than in the order confirmation, the Seller provides information on the functionality, compatibility and interoperability of the Product to the extent relevant for the given Product.

The Buyer acknowledges that:

  • the Product may be intended only for a specific platform, platform version or technical environment,
  • the Product may use activation or licensing mechanisms,
  • the Product may require security or compatibility updates,
  • failure to install a recommended or announced update may, to the extent permitted by law, limit rights arising from defects if the availability of the update and the consequences of not installing it were properly communicated to the Buyer.

If stated for the Product, agreed in the contract or required by law, the Seller will provide updates for the period required by law, by the Product description or by an individual agreement. If the law permits limiting future updates, the Buyer must be informed about such limitation clearly and understandably before the contract is concluded.

9. Rights arising from defects and complaints

The Seller is liable to the Buyer for defects in the Product to the extent provided by law and by these business terms and conditions.

For digital content supplied as a one-time performance, the Buyer may notify a defect that appears within two years from the time the Product was made available. If the digital content is supplied on a continuous basis for a certain period, the Buyer may notify a defect that appears or occurs during the term of the obligation.

If the digital content is defective, the Buyer may request that the defect be remedied unless this is impossible or disproportionately costly. The Seller will remedy the defect within a reasonable time after it has been notified so as not to cause significant inconvenience to the Buyer, taking into account the nature of the digital content and the purpose for which it was acquired.

If the Seller fails to remedy the defect in accordance with the previous paragraph, the defect reappears after remedy, the defect constitutes a material breach of contract, or it is clear that the defect will not be remedied within a reasonable time without significant inconvenience to the Buyer, the Buyer may request a reasonable price reduction or withdraw from the contract. The Buyer may not withdraw if the defect is insignificant.

The Buyer may file a complaint in particular by e-mail to info@zserver.cz. The complaint should include at least:

  • identification of the Buyer,
  • the order number or invoice number,
  • identification of the Product complained about,
  • a description of the defect and how it manifests,
  • information about the platform and environment used, if relevant to the assessment,
  • attachments if available, for example screenshots, logs or error messages.

If necessary due to the nature of the complaint, the Buyer will provide the Seller with reasonable cooperation to verify whether the defect is caused by the characteristics of the Product or by an unsuitable technical or software environment of the Buyer, provided that the Buyer was clearly and understandably informed about the environmental requirements before the contract was concluded.

The Seller will provide the Consumer with a confirmation of receipt of the complaint and, after the complaint has been handled, also a confirmation of the date and method of handling the complaint or a written explanation of rejection if required by law.

If the complaint concerns digital content or a digital service, it will be handled within a reasonable time taking into account the nature of the digital content or digital service and the purpose for which the Buyer required it. In other cases, the statutory time limit applies, usually 30 days, unless the law provides otherwise.

The Seller is not liable for defects arising solely as a result of:

  • use of the Product contrary to the documentation or intended purpose,
  • use in an unsupported technical environment if the Buyer was informed in advance,
  • unauthorised intervention by a third party,
  • intervention in the Product code contrary to the license terms,
  • failure to install an update about which the Buyer was duly informed, if permitted by law.

10. Support

Unless stated otherwise for the Product or in the contract, the Product price does not include unlimited individual technical support, consultations or custom development work.

If the Product states that the price includes support or updates for a certain period, the scope specified for that specific Product applies.

Support usually covers only:

  • installation and basic activation of the Product,
  • resolution of reproducible defects in the Product,
  • basic operational questions regarding the Product.

Support normally does not cover custom modifications, development of new functions, interventions in third-party modules, server administration, recovery after third-party intervention or issues caused by an unsupported environment.

11. License and intellectual property

The Product is protected by copyright and other intellectual property rights. By purchasing the Product, the Buyer does not acquire ownership of the copyrighted work, but only a license to use the Product within the scope defined by the license terms.

The license terms form an integral part of the contractual relationship to the extent they apply to the relevant Product.

12. Personal data protection

Information about personal data processing is provided in a separate document published on the Seller's web interface. These business terms and conditions do not replace the information duties related to personal data protection.

13. Out-of-court consumer dispute resolution and supervision

If the Buyer is a Consumer, they may first contact the Seller with a request for remedy in the event of a dispute.

In the Czech Republic, out-of-court consumer dispute resolution is mainly handled by the Czech Trade Inspection Authority (Česká obchodní inspekce, ČOI). A Consumer may file a proposal for out-of-court resolution no later than one year from the day on which the relevant right was first exercised against the Seller.

The Consumer may also submit a complaint to a supervisory authority, in particular the Czech Trade Inspection Authority, or to the competent municipal trade licensing office, if applicable under the relevant legislation.

14. Final provisions

These business terms and conditions apply mutatis mutandis even if the Buyer is a Business customer, unless these business terms and conditions or an individual agreement provide otherwise. Provisions which by their nature apply only to Consumers do not apply to Business customers.

Legal relationships between the Seller and the Buyer are governed by the laws of the Czech Republic and directly applicable European Union legislation. If the Buyer is a Consumer with habitual residence in another Member State of the European Union, the mandatory consumer protection rules of that state remain unaffected.

The Seller may unilaterally amend or supplement these business terms and conditions. For any specific order, the version effective at the moment the order is submitted by the Buyer is decisive.

These business terms and conditions become effective on 2026-06-03.
