There is no official way to know if two persons are chatting on WhatsApp. However, you can try some methods to find out their online status and activity, such as calling them, using WhatsApp web, or using monitoring apps.
Two blue check marks appear when all participants have read your message. Read receipts reset when you edit a message, so you can see who viewed your updates.
Disappearing messages is an optional feature you can turn on for more privacy. When you enable disappearing messages, you can set messages to disappear 24 hours, 7 days, or 90 days after the time they are sent, unless that message is kept.
Catch a WhatsApp Cheater Using the mSpy App
This spy app is an advanced cell phone tracking app that can allow you to see all the activities on your partner's WhatsApp. mSpy shows you everything on WhatsApp, from the contacts your spouse is chatting with, to the messages, and even media files shared.
Messages sent in Vanish Mode disappear once seen or when the chat is closed so they can't be recovered.
In order to retrieve deleted WhatsApp messages, you must have enabled Chat Backup in the app's settings. To reach this, tap the Settings tab. It's on the bottom bar of the iPhone app; on Android, open the three-dot menu at the top-right and choose Settings. From there, head to Chats > Chat backup.
Tap the person's name or phone number at the top of the screen to open the contact info page. Scroll to the bottom of the contact info page and select Disappearing Messages. In the “Message Timer” section, select the duration beyond which messages in the conversion will be deleted for both parties.
Please note, WhatsApp is end-to-end encrypted and messages are stored on your device, so someone accessing your account on another device can't read your past conversations.
Next to each status, an eye icon shows you how many people have viewed it. By swiping your finger up on a status, you'll see who recently viewed it.
Any messages sent to a contact who has blocked you will always show one check mark (message sent), and never show a second check mark (message delivered). Any calls you attempt to place will not go through.
Last seen and online tell you the last time your contacts used WhatsApp, or if they're online. If a contact is online, they have WhatsApp open in the foreground on their device and are connected to the Internet. However, it doesn't necessarily mean the contact has read your message.
How Long Do Disappearing Messages Stay on Chats? Disappearing messages stay on chats for as long as you have not read them. Once you read it, the message disappears.
It is advisable to not turn on disappearing messages for workplace chats because you might end up losing important texts if you have not starred them. Rather than asking your colleague or manager to resend some details, it is best you don't turn this feature on at all.
With disappearing messages, any text you send will expire after a pre-specified period of time. The recipient will be alerted to this timer, which will not begin until they have viewed the message. Once expired, the message is deleted from all devices (although screenshots are possible).
Will the Other Person Know That Vanish Mode Is Active. Vanish mode is activated for both sides i.e., sender and receiver of the message. They will see a different screen with Vanish mode written promptly on the chat. So yes, the other person will come to know about the Vanish mode.
If you're like us, you're probably wondering what, exactly, Vanish Mode does. The new setting makes all of your messages disappear shortly after sending them with no trace of them left behind.
Neither the sender nor the recipient can read them when they disappear from the chat. This function erases the information from the conversation history. But if the parental control app is installed on your child's device, you'll be able to see this information in your dashboard.
Finding an Android device
If your spouse is logged into Google on a family computer, you can simply go to "Google Find My Device" to see the phone's location. Click on the picture in the upper right corner of the Google search page to see which account is logged in. Often, family members don't bother to log out.
