We designed iMessage to use end-to-end encryption, so there's no way for Apple to decrypt the content of your conversations when they are in transit between devices. Attachments you send over iMessage (such as photos or videos) are encrypted so that no one but the sender and receiver(s) can access them.
Apple iMessage texts can get intercepted by someone close to you using a connected device. There are a couple of ways they can do this. First, there's message forwarding. You can use this feature to forward messages to another device automatically.
Text messaging leaves an electronic record of dialogue that can be entered as evidence in court. Like other forms of written evidence, text messages must be authenticated in order to be admitted.
The IOS Messages app does not support the saving of text messages, nor are there any apps which really do this well (other than connecting to iTunes with a cable - ugh!). Contrastly, Android has an app like SMS Backup + which will automatically backup all call logs and text messages to Google folders (wirelessly).
Note: Deleted messages remain in your Recently Deleted folder for up to 30 days, and you can recover them.
Yes, it's definitely possible for someone to spy on your text messages and it's certainly something you should be aware of – this is a potential way for a hacker to gain a lot of private information about you – including accessing PIN codes sent by websites used to verify your identity (such as online banking).
End-to-end encryption
With watchOS, iOS, and iPadOS, your messages are encrypted on your device so they can't be accessed without your passcode. iMessage and FaceTime are designed so that there's no way for Apple to read your messages when they're in transit between devices.
Police are law enforcement agencies that have the right to ask for any data for security purposes. Many people hide their information in terms of photos or text messages from the police. However, police can effortlessly recover deleted Photos/Text/WhatsApp messages and almost everything from iPhone/Android.
Keeping Your Data Secure
So, can police recover deleted pictures, texts, and files from a phone? The answer is yes—by using special tools, they can find data that hasn't been overwritten yet. And these days, encryption isn't quite the silver bullet solution it once was.
iMessage is end-to-end encrypted. The phone number or email address you use is shown to the people you contact, and you can choose to share your name and photo. Apple retains limited information about the use of iMessage, such as whether your device is eligible to use iMessage, for up to 30 days.
Sign in to the Apple ID website (https://appleid.apple.com) and review all the personal and security information in your account to see if there is any information that someone else has added. If you have two-factor authentication turned on, review trusted devices for any devices that you don't recognize.
It is the most privacy-conscious firm out there. Apple only stores the information that is necessary to maintain users' accounts. This is because their website is not as reliant on advertising revenue as are Google, Twitter, and Facebook.
Using iCloud to Spy on Spouse
Your spouse could spy on you through a shared iCloud account. Sharing an iCloud account with your spouse surrenders access to about everything on your iPhone. Your location, photographs, contacts, text messages, everything.
That's because the texts are being sent to an ID that is listed as an iMessage receive ID on both devices. See Settings > Messages > Send & Receive > You can be reached by iMessage at: Correct this so each device has a unique ID.
Formal discovery requires a party to disclose anything asked by the other party which is relevant and within the control of the party. This includes text messages (unless they were deleted). Failure to answer discovery may result in the finding of contempt against the spouse.
When you delete a text thread, it's stored in a folder on your iPhone's recently deleted messages file for 30 days. You can recover it or delete it permanently right then and there. That also means anyone can see your deleted messages if they have your passcode.
iMessages are not in your text log regardless of how they are sent.

And what if you want a more advanced monitoring solution? Then you need to check out Eyezy. The iMessage monitoring app is designed to let you see all their iMessages from any device of your choosing. That includes other iOS devices, Macs, Windows PCs, and even Androids.
If you want to protect your privacy, are you better off with an iPhone or an Android? The truth is, the average iPhone offers far more privacy than the average Android smartphone. If you're a casual user who has no interest in installing specialized software but still want to keep your privacy, stick with Apple.
The user's outgoing message is individually encrypted for each of the receiver's devices. The public encryption keys and signing keys of the receiving devices are retrieved from IDS.
iMessage texts contain a thing called end-to-end encryption that regular SMS texts don't. This is what protects your communications from getting intercepted by hackers or other unwanted third parties while going through networks.
On the Messages screen, swipe down to the Message History section, and tap Keep Messages. You'll notice it's set to keep SMS and iMessages Forever. Change it by tapping the 30 days option or 1 Year.
mSpy is just the app to put your mind at ease. By installing it on the user's device, you can view text messages on their phone. This includes all of their iMessages (messages sent between two iOS devices) and plain texts (messages sent between iPhone and Android).
If you see “Use your Apple ID for iMessage,” tap it and sign in with the same Apple ID that you use on your Mac, iPad, and iPod touch. In the "You can receive iMessages to and Reply From" section, make sure that your phone number and Apple ID are selected.
