Keeping a client's information secure must be every repair technician's primary concern. When making a repair, the technician must contractually ensure that the client's private information will not be shared in any way. It's the right thing to do, and it gives the client peace of mind that their sensitive information is contractually protected.
Wiping Computer User Data
When working with hardware destined for a new user, previous user data must be erased entirely. If user data isn't wiped properly, it may be accessible even after a new operating system is installed.
Think of it this way: computer data operates like the information in a textbook. Every file is listed in the book's index. If you tear out the index, the information in the book doesn't go away. It just makes it harder to find. Re-installing an operating system works the same way: only the index is destroyed.
Proper hard disk wiping goes further than just deleting the index. Every bit of information on the disk is overwritten, turning readable binary sequences into nonsense. To continue with the book example, proper hard disk wiping would be like turning every letter in the book into an X. Now, not only has the index been discarded, but the actual text has been rendered meaningless.
Always use proven methods to erase hard drives.
Wiping Smartphone and Tablet Data
Wiping user data from a smartphone or tablet works slightly differently. The basic mechanics are the same: deleting a file erases the indexed file path but not the content. Private user data can be found after the file is deleted. The difference is that many smartphones and tablets are '''encrypted'''.
When erasing data from an encrypted device, a technician needs only to destroy the key code that makes the data usable. Once the key is destroyed, all data will be unreadable, even though it hasn't been overwritten.
Easy solutions for entirely overwriting the contents of smartphones and tablets aren't available. Many smartphones and tablets may be "factory reset" or "hard reset." This process erases all user data by destroying the encryption key. If the device is encrypted, use the following pathways listed below:
iPhone
Settings > General > Reset
- Since iOS 8, encryption is default.
Android
Menu > Settings > Privacy > Factory Data Reset
- KitKat is not encrypted by default
- Lollipop is not encrypted by default, despite what Google had previously announced

Could we get some more info on how to contractually ensure customers? Where do I go to get that setup? How does that even work? It reminds me of those big packets businesses have people sign or the pages of legal stuff I see on online stores and if that’s the case, do I need to hire someone to accomplish that? and if so, is there not a simple way to handle it myself? I could go on but I think you get it, thanks in advance!

Felix, my guess is you probably have some sort of business insurance that covers your activities. I believe the rider is called “Errors and Omissions.” Ensure you have that rider. Next step is yes, have a disclaimer on your repair order. It might be a good idea to check with your insurance carrier to see if they have canned/preferred verbiage for it.
