how to know who saved my number in whatsapp?

Yes, you can see if someone is online on WhatsApp if they didn’t save your number. If you have the person’s phone number, you can see when they were last online by opening WhatsApp and going to the Chats screen. Under the contact’s name, there is a green dot that indicates whether the person is currently online or not.

There’s no one definitive answer to this question. One possibility is that if you’ve given someone your phone number, they may save it in their phone contacts. Another possibility is that if someone has your phone number, they may search for it on the internet.

Yes, it is possible to know who viewed your WhatsApp profile. However, this information is not publicly available. You would need to use a third-party app to access this information.

Yes, WhatsApp offers a privacy setting that allows users to hide their last seen, profile photo, and status from other users. To enable this setting, open WhatsApp and go to Settings > Account > Privacy.

There is no way to prevent someone from adding you to a WhatsApp group. However, you can leave the group at any time.

There is no foolproof way to hide your WhatsApp account from others, as the app is not designed with privacy in mind. However, you can take some steps to make it more difficult for people to find your account:
Use a different phone number for WhatsApp than the one you use for other services.
Don’t add your phone number to your public profile on social media or elsewhere online.
Enable two-factor authentication on WhatsApp.

Yes, if you have WhatsApp installed on your phone and your friend has it installed on theirs, then they can see your messages. WhatsApp is a cross-platform app, which means that it is available on Android, iOS, Windows Phone, and BlackBerry. This also means that your messages are not encrypted unless you are using the app’s “secret chat” feature.

There is no built-in feature to appear offline on WhatsApp, but there are a few workarounds. One is to set your phone to airplane mode, which will disable all data and cellular services. Another is to use an app like Go Offline or WiFi Only Mode, which will allow you to selectively disable your internet connection for specific apps.

There is no sure way to read WhatsApp messages without blue ticks, as this feature is designed to show when a message has been read. However, one workaround is to open the app and then quickly close it again, which may trick the sender into thinking that the message has not been read.

WhatsApp is not safe because it is an unencrypted messaging app. This means that messages sent over the app are not protected, and can be easily intercepted by hackers.

Yes, you can login to someone else’s WhatsApp account as long as you have their phone number and password.

Yes, deleted WhatsApp messages are still stored on your phone until they are overwritten by new data. If someone has access to your phone, they could potentially read your deleted messages.

WhatsApp is not a Chinese app. It was founded in 2009 by two American expats, Jan Koum and Brian Acton.

There is no one “best” WhatsApp, as different people prefer different features. However, some of the most popular features include group chats, voice and video messaging, and location sharing.

There is no definitive answer to this question as different chat apps offer different levels of security. However, some of the more secure chat apps include Signal, Wickr, and Telegram. These apps encrypt your messages so that only the intended recipient can read them, and they also delete messages after a certain amount of time so that they cannot be accessed or recovered even if someone manages to get hold of them.
