Therefore, if the device is still working you should try to make a backup before giving the device in to us for repair. We may in addition make our own backup before starting a risky 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 insure yourself 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 device is encrypted. We will not divulge the contents of any data we see to anyone else.
