1.13. PRO Add-on — additional paid functionality of the Software, the composition, terms of purchase and use of which are established by a separate Public Offer for the use of the «SvetoMaster PRO» Add-on, hereinafter the «PRO Offer».

1.14. Separate Agreement — an agreement signed by the Licensor and an individual entrepreneur or legal entity, together with its technical annex, that determines the terms for granting and using a paid License. It is executed on paper or as an electronic document signed by the Parties with qualified electronic signatures through an electronic document interchange operator.

1.15. Agreement — the license agreement for the use of the Software, concluded by acceptance of this Offer by an individual or by conclusion of a separate agreement with an individual entrepreneur or legal entity.

2. Application of the terms and conclusion of the Agreement

2.1. Before making payment, the Licensee must review this Offer, the chosen Plan, the description of the Software, the system requirements, the term of the License, the number of permitted Computers and the amount of the license fee.

2.2. For an individual, acceptance of the Offer in the part concerning the purchase of a paid License is full payment of the chosen Plan at the price shown in the Personal Account immediately before payment. The Agreement is deemed concluded from the moment the execution of the payment is confirmed by the credit institution or payment service serving the Licensee.

2.3. In the part concerning the Trial Period, the Agreement is deemed concluded after the «I accept the terms of the license agreement» button is clicked in the installer and the Software is subsequently first used. Where these actions are performed by an Authorized User of an individual entrepreneur or legal entity, the Licensee in respect of the Trial Period is the individual entrepreneur or legal entity represented by that Authorized User.

2.4. For an individual entrepreneur or legal entity, a paid Agreement is concluded only by the Parties signing a Separate Agreement and its technical annex on paper or with qualified electronic signatures through an electronic document interchange operator. Payment of an invoice issued under it is performance of the already concluded Separate Agreement and does not replace its signing. Acceptance of these terms by an Authorized User in the installer confirms an intention to comply with technical operating rules on behalf of the Licensee, but is not the conclusion of a Separate Agreement or an independent purchase of a paid License, does not impose a payment obligation on the Authorized User and does not amend the signed terms. In the event of a discrepancy, the Separate Agreement and its technical annex prevail.

2.5. Where the Licensee is an individual entrepreneur or legal entity, the Software may be used by its employees and other Authorized Users in the interests of the Licensee and within the limits of the purchased License. The Licensee ensures their compliance with the Separate Agreement and its technical annex.

2.6. Information about the chosen Plan, price, term, number of permitted Computers and other parameters of an individual’s purchase is sent to the email address and/or displayed in the Personal Account; for an individual entrepreneur or legal entity it is recorded in the signed Separate Agreement and the invoice issued under it. Such information forms part of the Agreement.

3. Subject of the Agreement

3.1. The Licensor grants the Licensee, for a fee or free of charge during the Trial Period, the right to use the Software on the terms of a simple (non-exclusive) license, and the Licensee accepts that right and complies with the limits of use established by the Agreement.

3.2. The Licensee is granted the following ways of using the Software:

3.2.1. downloading the installation file from the Website or another source officially specified by the Licensor;

3.2.2. reproducing the Software by recording and storing a copy of it in the memory of the permitted number of Computers;

3.2.3. launching and applying the Software’s functionality for its direct purpose to control compatible lighting equipment;

3.2.4. making one backup copy of the installation file solely for use within the limits of the purchased License.

3.3. The License is simple (non-exclusive). The exclusive right to the Software, ownership of the program code and the right to grant licenses to other persons remain with the Licensor.

3.4. The Software is provided in the form of object (executable) code. The Licensee is not transferred the source code, rights to trademarks and other means of individualization, or any other rights not expressly granted by the Agreement.

3.5. The territory of the License is worldwide, unless another restriction is specified in the Plan or a separate agreement.

3.6. Projects, scenes, chases, playlists, custom fixture profiles, settings and other user materials created by the Licensee or an Authorized User belong to the Licensee or another respective rightsholder. The Licensor does not acquire exclusive rights to such materials as a result of their creation, storage or processing by means of the Software.

3.7. If the Licensee, on their own initiative, transfers a user project, operation logs, a diagnostic report or part of them to the Licensor for technical support, the Licensee permits the Licensor to technically reproduce, store, process and transfer such materials to engaged technical contractors solely to the extent and for the period necessary to provide support.

3.8. The PRO Add-on is not included in the main License. The composition, terms of purchase and use of the PRO Add-on are determined by the PRO Offer. The Licensor is entitled to provide users, free of charge, with bonuses under marketing and referral programs; such bonuses are governed by the PRO Offer.

4. Types and terms of Licenses

4.1. Trial license is valid for the period shown before the Trial Period begins. When the Trial Period ends, access to features requiring a valid main License ceases.

4.2. A monthly License is granted for one calendar month, an annual License for one calendar year from the moment the License is assigned paid status, unless a different method of calculating the term is expressly specified before payment or in a separate agreement.

4.3. Perpetual license («forever»). The right to use the purchased principal version of the Software is granted for the entire term of the exclusive right to the Software. Such a License includes Minor Updates of the purchased principal version, if released by the Licensor, but does not include subsequent Major Updates.

4.4. Monthly and annual Licenses, during the paid term, allow the use of Minor and Major Updates available to the Licensee that are released during the term of the License. After the paid term ends, the right to use the Software under the corresponding License ceases.

4.5. The release of updates, their frequency and content are determined by the Licensor. The purchase of a License does not entail the Licensor’s obligation to release a particular update or new feature, unless such an obligation is separately specified before payment or in a separate agreement.

4.6. Individual features of the Software may be designated by the Licensor as experimental, preliminary or in testing («beta»). Such features are provided on an «as available» basis, may operate unstably, change or be removed from the Software; their presence, composition and results are not among the expressly stated characteristics of the Software.

4.7. There is no automatic renewal. Payments for a new month, year or new principal version of the Software are not charged to an individual without their separate action and consent. To continue using a term-limited License, an individual makes a new purchase independently; the procedure for renewing the License of an individual entrepreneur or legal entity is determined by a separate agreement.

4.8. When an individual purchases a new term-limited License, its term and the manner in which it is added to an already valid term are displayed before payment.

4.9. The end of the main License does not terminate a previously acquired right to use the PRO Add-on and does not shorten its term in the cases and to the extent provided by the PRO Offer. At the same time, actual use of the PRO Add-on is carried out within the Software and is possible where there is a valid right to use the Software.

4.10. Upgrade from an annual License to a perpetual one. During the paid term of an annual License, a Licensee who is an individual is entitled to replace it with a perpetual License by paying the difference between the price of the perpetual License effective at the moment of the replacement, determined with account of the discounts and special offers applicable to that Licensee, excluding promo codes, which do not apply to such an additional payment, and the license fee actually paid by them for the most recent paid annual period. The additional payment may not be less than the minimum amount displayed in the Personal Account before payment. Upon such replacement the annual License terminates and the perpetual License is granted from the moment the payment is confirmed in accordance with Section 8; the unused part of the annual term is not separately compensated and does not extend the term of the perpetual License, and the fee previously paid is taken into account solely as provided by this clause. The replacement is a right and not an obligation of the Licensee: instead of it, the Licensee may purchase a new paid period under the current Plans, and in that case a subsequent replacement takes into account the license fee paid for the most recent paid annual period. After the annual License expires, a perpetual License is purchased on general terms without crediting previously paid amounts.

5. Activation and use on Computers

5.1. The License is linked to the Account identified by an email address.

5.2. The number of Computers on which simultaneous Activation and use of the Software are permitted is determined by the Plan or a separate agreement. Unless otherwise expressly specified before payment or in a separate agreement, one License permits simultaneous Activation and use of the Software on no more than two Computers.

5.3. The limit on the number of Computers established at the time of purchase of the License is retained for its term. A subsequent change of Plans applies only to new purchases and does not reduce the scope of rights previously granted.

5.4. To link the License to a Computer, the Software may process technical information that allows the device to be identified, and derived values generated on its basis. The composition of the processed data and the procedure for its processing are determined by the Personal Data Processing Policy.

5.5. The Licensee is entitled to deactivate an unused Computer in the Personal Account and activate another Computer within the established number. The Licensor is entitled to apply reasonable technical measures against automated or abusive repeated changes of Computers, without depriving a bona fide Licensee of the ability to transfer the License.

5.6. Initial Activation, verification of the License status and periodic confirmation of its validity may require an Internet connection. The current requirements for the frequency of verification are communicated to the Licensee before download or in the Software interface.

5.7. Upon a substantial change in the hardware configuration, a Computer may be identified as a new device. In that case, the Licensee uses deactivation in the Personal Account or contacts technical support.

5.8. For a License of an individual entrepreneur or legal entity, the Account and email address to which the License is linked may be specified in the separate agreement. Such a Licensee is entitled to contact technical support to change the responsible email address or Authorized User, confirming the authority of the person who sent the request.

6. Account and electronic interaction

6.1. The Licensee must provide a valid email address, ensure its availability and keep the Account login credentials confidential. Where the Licensee is an individual entrepreneur or legal entity, the Account credentials may be provided only to its Authorized Users.

6.2. Actions taken after authorization in the Account are deemed taken by the Licensee until the Licensor is notified of unauthorized access. If unauthorized access is suspected, the Licensee or Authorized User must, without undue delay, change the password and notify technical support.

6.3. The terms of registration, use and deletion of the Account are governed by the Website’s User Agreement.

6.4. Deletion of the Account by an individual on their own, or a confirmed request for its deletion, is an expression of the will to cease use of the Account and the associated rights. Deletion of the Account of an individual entrepreneur or legal entity is carried out at the request of its authorized representative or in another manner established by the separate agreement.

6.5. After deletion, access to the Account, Personal Account and Software ceases immediately; Licenses associated with the Account terminate without restoration, and unused terms and the license fee are not refunded on the ground of voluntary deletion of the Account. Before deletion, the Licensee is notified of these consequences and confirms their decision.

6.6. This section does not limit the Licensee’s mandatory rights arising from the failure to grant a paid right, a material defect of the Software or another breach by the Licensor.

6.7. Messages relating to payment, the License, Activation, term, Account security and amendment of this Offer are sent to the Account email address and/or posted in the Personal Account and are deemed received by the Licensee on the day they are sent or posted. The risk of non-receipt of messages due to specifying an invalid address, its unavailability or the operation of filters is borne by the Licensee.

7. Cost and payment procedure

7.1. For an individual, the amount of the license fee is determined by the chosen Plan, taking into account discounts, promotions and special offers in effect at the time of payment, and is shown in the Personal Account immediately before payment. The price confirmed by the individual upon payment forms part of the Agreement, is recorded in the electronic confirmation of purchase and does not change with respect to the already paid License.

7.2. For an individual entrepreneur or legal entity, the amount of the license fee, the procedure and term of payment are determined by the signed Separate Agreement and the invoice issued under it.

7.3. Payment by an individual is made in non-cash form using the methods available on the Website. The payment obligation is deemed fulfilled from the moment the execution of the payment is confirmed by the credit institution or payment service serving the Licensee.

7.4. The Licensee’s expenses related to the services of their bank, telecom operator or other chosen intermediary are not included in the cost, unless expressly stated otherwise.

7.5. The Licensor does not store the Licensee’s full bank card details, as payment processing is carried out by a third-party payment service.

8. Provision of the paid License

8.1. Upon receipt of payment confirmation, the Licensor assigns the License in the Account a status corresponding to the chosen Plan or separate agreement. This is usually done automatically without a separate request from the Licensee.

8.2. The right to use the Software is deemed granted from the moment when, at the same time, the corresponding License status is reflected in the Account and the Licensee is provided with the technical ability to download, activate and use the Software within the chosen Plan or separate agreement.

8.3. If the paid License status has not appeared or the use of paid functionality is impossible, the Licensee sends a request to technical support, specifying the Account address, the date and amount of payment, and information allowing the transaction or separate agreement to be identified. The Licensee must not transfer the full bank card number and other excessive payment data.

8.4. The Licensor verifies the payment and remedies a confirmed error within a reasonable time.

9. Rights and obligations of the Licensor

9.1. The Licensor is obliged to:

9.1.1. grant the Licensee the right to use the Software in accordance with the chosen Plan or separate agreement;

9.1.2. ensure the possibility of Activation and verification of the License status, except during maintenance, force majeure and failures beyond the Licensor’s reasonable control;

9.1.3. remedy confirmed technical errors that prevent the use of paid functionality within a reasonable time, taking into account the nature of the error.

11.2. The Licensee compensates the Licensor for documented losses arising from its breach of this section, the requirements of the law or the rights of third parties, within the limits established by law.

12. Third-party components and materials

12.1. The Software may include components, lighting fixture profiles, fixture libraries, gobo images and other materials created by third parties or obtained from open sources. Rights to such materials belong to the respective rightsholders, and their use is governed by the applicable open or other licenses. Corresponding notices may be contained in the Software, the documentation or a separate list of third-party components.

12.2. The Licensor does not warrant that a third-party, imported or user-created fixture profile fully corresponds to a particular model, firmware version or actual hardware configuration, and is not liable for the consequences of its use.

12.3. Before using such a profile, the Licensee or Authorized User must verify the assignment of channels, value ranges, addressing and the safe behavior of the fixture.

13. Withdrawal from the Agreement and refunds

13.1. Before purchasing a paid License, the Licensee is provided with the opportunity to use the Trial Period, the duration of which is communicated before it begins. The Trial Period is intended for evaluating the features, interface, performance and compatibility of the Software with a particular Computer and equipment.

13.2. After the right of use has been duly granted under clause 8.2, the Agreement does not provide for an unconditional contractual refund of the license fee for reasons unrelated to a breach of the Agreement by the Licensor. Such reasons include, in particular, the cessation of the need for the Software, non-use of the granted right, failure to review the system requirements, or incompatibility with equipment that was not designated by the Licensor as supported.

13.3. Clause 13.2 does not limit the Licensee’s rights if the right of use has not been granted, the paid status has not been activated, the Software does not correspond to expressly stated characteristics, a material defect is found or a refund is mandatory under law or a separate agreement.

13.4. An erroneous duplicate payment is subject to refund after verification, if it was not applied towards a separate License or another obligation of the Licensee.

13.5. A claim is sent to the email address specified in section 20 and must contain the Account email address, the date and amount of payment, the reason for the request and information sufficient to identify the transaction or separate agreement. A refund, where there are grounds provided by the Agreement, the separate agreement or law, is made by the same method used for payment, if this is technically possible and another method has not been agreed by the Parties.

13.6. The terms of withdrawal from the Agreement and refunds for an individual entrepreneur or legal entity may be additionally established by a separate agreement.

14. Technical requirements, support and updates

14.1. Current system requirements are published on the Website and/or in the Software documentation. The Licensee must review them before payment.

14.2. The fact that a device operates over a standard protocol does not in itself guarantee its compatibility with the Software. Compatibility also depends on drivers, firmware, connection quality and the manufacturer’s implementation of the device.

14.3. The Licensor does not warrant the compatibility of the Software with all existing and future devices, driver versions and operating systems. This restriction does not apply to compatibility expressly stated for the corresponding version of the Software.

14.4. The Software may periodically require an Internet connection for Activation, License verification, downloading updates and the operation of network features.

14.5. Technical support is provided through the contacts published on the Website. Unless another period is agreed before payment or in a separate agreement, requests are handled within a reasonable time, taking into account their complexity and order of receipt.

14.6. The Licensor is entitled to carry out maintenance. Where possible, information about scheduled work that may substantially limit the use of paid functionality is published in advance.

14.7. The Software may automatically check for updates and notify the Licensee of their release and, where the corresponding setting is enabled, automatically download and install updates. Updates provided by the Licensor form part of the Software and are governed by this Agreement.

14.8. A particular update may be designated by the Licensor as necessary to ensure information security, compatibility with the server infrastructure, Activation or verification of the License status. Information about the need to install such an update and the possible consequences of refusal is communicated to the Licensee in the Software interface or on the Website.

14.9. Failure to install an update does not in itself terminate a perpetual License, but may lead to restriction of network features if their further operation is objectively impossible without the corresponding update. The Licensor is not liable for the consequences of the Licensee’s refusal to install such an update.

15. Specifics of controlling lighting equipment

15.1. The Software is a tool for controlling lighting equipment. The final result depends on the operator’s actions, the connection scheme, DMX addressing, fixture profiles, the serviceability of the equipment, drivers, cables, power supply and operating conditions.

15.2. Before first using the equipment, before an event, and after changing the project, addressing, fixture profiles, drivers or connection scheme, the Licensee or Authorized User must verify the scenes, commands, movement limits of fixtures and the behavior of the equipment under safe conditions.

15.3. The Software must not be used as the sole means of preventing dangerous movement of equipment, blinding of people, overheating, fire or other dangerous consequences. The necessary hardware limiters, emergency shutdown and operator control are ensured by the Licensee, the Authorized User and the owner of the equipment.

15.4. The Software is not intended for controlling life-support systems, emergency protection and other critical systems whose failure may directly harm human life or health.

15.5. The use of bright, rapidly changing and strobing lighting effects may cause adverse reactions in certain individuals, including persons with photosensitivity or photosensitive epilepsy. The Licensee and Authorized User independently determine the admissibility of applying such effects, control their brightness and frequency, comply with applicable safety requirements, take into account the characteristics of the audience and ensure the ability to immediately stop the effect.

15.6. When using Art-Net, sACN, OSC and other network control protocols, the Licensee independently ensures the security and isolation of the local network, restriction of access to it and the absence of unauthorized sources of control commands. Certain protocols may not provide encryption, sender authentication or protection against command spoofing at the protocol level.

15.7. Before an event, the Licensee or Authorized User must check the network configuration, take reasonable measures to prevent the connection of unknown or untrusted devices, and verify the stability of the connection and the operation of the equipment under conditions as close as possible to actual use.

15.8. The stability of generating and transmitting control commands may depend on the performance of the Computer, its load by third-party processes, power-saving settings, the throughput and state of the USB bus, the serviceability of the controller and cables, the compatibility and stability of drivers, and the operation of other installed software.

16. Liability of the Parties

16.1. The Licensor is liable for the conformity of the granted right with the chosen Plan or separate agreement and with the expressly stated characteristics of the Software. In the part not expressly stated, the Software is provided «as is» to the extent permitted by law.

16.2. The Licensor is not liable for malfunctions, delays, connection interruptions and other consequences caused by unsupported or faulty equipment, third-party drivers, the Computer’s power-saving settings, restrictions or failures of the USB bus, malware, changes to the operating system, breach of instructions, incorrect addressing or connection of equipment, operator actions, or the use of experimental features (clause 4.6), in the absence of a causal link with a defect of the Software.

16.3. The Licensor is not obliged to store user projects and ensure the possibility of their recovery, unless a cloud storage or backup feature is expressly stated on the Website, in the Software interface or a separate agreement.

16.4. To the maximum extent permitted by applicable law, the Licensor is not liable for lost profit, lost revenue, the disruption, delay or improper conduct of an event, reputational harm, the costs of engaging third parties, the loss or damage of user data and other indirect losses arising in connection with the use or inability to use the Software.

16.5. To the maximum extent permitted by applicable law, the Licensor’s aggregate liability under the Agreement is limited to the amount of the license fee actually paid by the Licensee for the License in the use of which the ground for liability arose.

16.6. The limitations established by clauses 16.4 and 16.5 apply to a Licensee who is an individual purchasing the Software for personal, family or household needs only to the extent permitted by consumer protection law.

16.7. Clauses 16.2–16.5 do not exclude the Licensor’s liability where the loss or damage of data or other losses are directly caused by a confirmed defect of the Software and such liability cannot be excluded or limited by law.

16.8. The Licensee is liable for the actions of its Authorized Users within the limits provided by law and the separate agreement.

16.9. No provision of the Agreement excludes or limits the Licensor’s liability and the Licensee’s mandatory rights in cases where such exclusion or limitation is prohibited by law.

17. Force majeure

17.1. A Party is released from liability for breach of an obligation due to force majeure in the manner established by law, having notified the other Party within a reasonable time by an available means.

17.2. If force majeure prevents the provision of paid term-limited functionality for a prolonged period, the term of the corresponding License is extended by a commensurate period, or the Parties determine another consequence in accordance with the law, the separate agreement and the nature of the obligation.

18. Processing of personal data

18.1. The Licensor processes personal data necessary for concluding and performing the Agreement, Activation, maintaining the Account, making payments, preventing abuse and fulfilling obligations established by law.

18.2. The categories of data, purposes, legal grounds, storage periods, information about third parties and the ways of exercising the rights of the personal data subject are determined by a separate Personal Data Processing Policy posted on the Website.

18.3. Consent to advertising and marketing messages, if sent, is obtained separately and is not a condition for purchasing the License.

18.4. When a technical failure prevents the Software from operating (abnormal termination, failure to initialise a DMX output interface, an unsuccessful integrity check of the installed files), the Software sends the Licensor a short technical report about that failure. The report contains only: the type of failure, the class and a brief description of the error, the file name of the program module without its path, the Software version, the operating system version and an anonymous installation identifier. The report contains no names or paths of the Licensee’s files, no project content, no credentials and no Software log files; any line in which a file path is detected is not transmitted. Reports are sent no more than once per day for each type of failure and are used solely to detect and remedy defects in the Software.
