Be it photos, contacts, messages, notes, or anything else, these technologically advanced programs make sure that the data has been deleted for one and all. Well! In that case, you can always look for an iPhone data eraser software and permanently delete the data.
Whether you are giving it to your younger sibling, or someone else, the data can still be recovered using advanced tools. When you are worried about your privacy and data security, simply deleting your data before selling your iPhone won’t serve you well.
