   3.10. If the Software loses its connection to the License Server and Braiins was therefore not able to conduct the verification procedure under the Section 3.9. hereof the cryptocurrency mining device will only use 95 % of its processing power (so called hash rate) until the next verification procedure is successfully conducted. You acknowledge that this is not an error, misfunction, or penalty, but rather an intended function of the Software.

  4.7. You acknowledge, that the Software may transmit certain information from Your cryptocurrency mining device (such as frequencies of chips, readings from temperature sensors, fan speed etc.) to Braiins. Braiins is entitled to use the information for provision of support to You, for performance of this Agreement, and for statistical analysis and improvements of the Software.


  5.1. You undertake to pay Braiins license fees for the License granted herein. The license fees shall be paid (provided) in the non-monetary form specified below in this section 5 of this Agreement  

  5.2. As license fees You will provide to Braiins a portion of the processing power generated by any and all cryptocurrency mining devices on which the Software is used. The processing power is provided to Braiins when Your cryptocurrency mining device has used the agreed processing power to perform certain processing operations (for the purpose of cryptocurrency mining) that were designated and sent to You by Braiins. You must allow Your cryptocurrency mining device to perform such processing operations without interference (especially You must not interfere with input data and with results of such operations).

Such changes or amendments are effective thirty (30) days after the new Fee List or information have been published on the Website. If the percentage is visibly indicated neither on the Website, nor in the Fee List issued by Braiins, nor was the percentage otherwise agreed upon, the percentage shall be 2,5 %.

  5.5. The respective portion of the processing power shall be provided to Braiins at all times when the cryptocurrency mining device and its processing power are being used regardless of the purpose for which they used.

  5.6. You acknowledge that embedded features of the Software enable the Software to automatically assign the amount of processing power corresponding to the license fees to perform processing operations designated and sent to You by Braiins.

  5.7. You acknowledge that due to the nature of processing power and processing power routing it is not technically possible to always assign the exact percentage of processing power. Therefore, You acknowledge that the amount of processing power actually assigned by the Software at the start of each session is random and it takes few seconds before a correct percentage of processing power is assigned. After that (for the same reasons) the amount of processing power assigned at any given time to perform processing operations for Braiins may be as much as 10 % higher or lower than the amount agreed above according to the section 5 hereof.

  5.8. In the event that the amount of assigned processing power is higher than the agreed amount as described in the Article 5.7. hereof, the difference constitutes portion of license fees as well and is not refundable to You.

  7.7. If the warranties and liabilities disclaimers above are found void or invalid or otherwise unenforceable, You agree that total liability of Braiins is limited to the monetary value of the total amount of processing power received by Braiins from You in the period of four (4) months immediately preceding the event or circumstance giving rise to such liability (the monetary value is calculated as of the moment when the processing power was provided to Braiins).
