Primarily, I mean the spouse is deceived into thinking he, or she, has some right to privacy and can lock their spouse out of their electronic life.
Secondarily, any spouse doing so is practicing a form of deception. Husbands and wives, Christian or not, please do not be deceived into making poor choices and do not practice deception with your spouse. (Also, children do not have a right to electronic privacy either.)
Please understand that when you said: "I do"; you forfeited the right to be your own person. The two of you became one person and you cannot be in the business of keeping secrets from yourself. There is not a single person walking on the planet today that you should be closer to, than your spouse. No one should know you better than your spouse. When you said: "I do" to Jesus Christ, for salvation, you agreed to die to yourself; or have you forgotten? That means all forms of selfishness.
Revelation is key to relationships. God revealed Himself to us through Jesus Christ and through the Bible. We must also reveal ourselves to one another in order to have a real relationship with another person. The person you reveal the most to should be your spouse. If that is not the case for you today, fix it, while you can. You can make a change today and start improving your marriage.
If your spouse does not have access your smart phone, ipad, computer and other devices, that needs to change today. Don't give me some lame excuse, practice full disclosure. If there is something there you will be ashamed of, then you have a problem.
1John 1:9 reads: "If we confess our sin, He is faithful to forgive our sin and forgive us from all unrighteousness". In short, repent, ask God for His forgiveness, take action to rid yourself of the sinful problem and seek forgiveness from your spouse. Repentance always involves a plan of action to be different, not just asking for forgiveness.
