In general, we will do our best to preserve all the data and settings on your computer or phone but that’s not always under our control so we can NOT guarantee this. Therefore, if the device is still working you should try to make a backup before sending a device to us for repair.
In any case, our insurance does NOT cover consequential damage to you or your business if data is lost or damaged. If such data is important to you, you should take out your own insurance against its loss.
Regarding confidentiality of the stored data – you should assume that anyone with physical access to your device can read all the data, unless the whole drive is encrypted (e.g. with Bitlocker) and no passwords are divulged to us. We will not divulge the contents of any data we see to any third party unless legally compelled.
