  • use the Software in ways that violate the law or the rights of third parties.

8. User files, the Library and Engine Sound

8.1. The Software works with the User’s files locally on the User’s computer. The Licensor does not upload the User’s files to its servers and has no access to them.

8.2. The User is responsible for holding the rights to the files they use (music, images, etc.).

8.3. The Library is available with Paid Access. Library items may be used only in the Software and on the User’s own vehicle for personal needs. The contents of the Library may change.

The exclusive rights to the sound synthesis software and other program code of the Service (including preparatory materials and the Engine Sound settings), to the texts, graphics and design of the Service pages, and to the Engine Sounds and Demos created entirely by the Licensor’s synthesis software belong to the Licensor (Arts. 1225, 1229, 1259, 1261, 1322 of the Civil Code). The Service as a whole is a complex object whose creation was organised by the Licensor (Art. 1240 of the Civil Code).

8.5. Engine Sounds marked with a "Recorded: …" line and their Demos were created by the Licensor by processing engine recordings that the Licensor uses under licenses from their right holders. The User receives no rights to the source recordings or to the Engine Sounds and Demos as separate objects; they are provided only for listening in the Service.

8.6. In addition to the restrictions in Section 7, the User may not:

  • extract, copy, record (including from the sound card or speakers into a separate audio file), download or store the Engine Sounds, the Demos or the source data the Service receives from the Licensor’s server;
  • circumvent the Service’s technical protection measures, including restoring data the server sends in protected form or retrieving it by automated means (Arts. 1299, 1309 of the Civil Code);

During a Paid Period the Licensor does not remove from Paid Access Engine Sounds available when the period began, except where use of a recording becomes impossible for reasons beyond the Licensor’s control (termination or restriction of the rights to the recording, a demand of the right holder or the law). In that case the Licensor notifies the User by e-mail and, where possible, replaces the sound with an equivalent one; the User may cancel the Subscription and get a refund of the part of the fee proportional to the remainder of the Paid Period.

8.8. In drive mode the browser, with the User’s permission, gives the page geolocation data. It is processed only in the browser on the User’s device and is not sent to the Licensor — see the Privacy Policy. Without permission the test mode with a virtual pedal is available.

10.3. Unless otherwise established by law, the Licensor’s total liability under this Agreement is limited to the fee paid by the User for the Paid Period in which the breach occurred (for the free version of the Software - none, as no fee is paid). This limitation does not apply to liability for an intentional breach (Art. 401(4) of the Civil Code) or where limiting liability towards a consumer is not permitted by law (Art. 400(2) of the Civil Code, Art. 16 of the Consumer Protection Law).

10.4. The parties are released from liability for non-performance caused by force majeure (Art. 401(3) of the Civil Code).

10.6. The driver must comply with the Road Traffic Rules, including not being distracted from driving. Choosing an Engine Sound and the volume and checking the sound with the Throttle pedal should be done while parked.

11.1. The User may cancel the Subscription at any time (Art. 32 of the Consumer Protection Law) in the Software or in the personal cabinet.
