In its notification, Customer will explain its reasonable grounds for objection. In the event Customer objects to a new sub-processor, Stackby will use commercially reasonable efforts to make available to Customer a change in the Services or recommend a commercially reasonable change to Customer’s configuration or use of the Services to avoid Processing of Customer Personal Data by the objected-to new sub-processor without unreasonably burdening Customer. If Stackby is unable to make available such change within a reasonable period of time, which will not exceed thirty (30) days, either Party may terminate without penalty the Processing of Customer Personal Data and/or the Agreement with respect only to those services which cannot be provided by Stackby without the use of the objected-to new sub-processor by providing written notice to the other Party.
