Truecaller is one of the most popular caller ID apps in the world and in some Asian and European countries, Truecaller is almost inescapable. The app provides a real service. It blocks spam calls automatically from your iPhone and tells you who is calling even if they aren't in your phone book. But on the flipside, this means that Truecaller has all your personal data. And it can seep into Truecaller's database even if you haven't signed up for the service (thanks to the magic of crowdsourcing).

If you want to make sure that your number and name aren't listed in the Truecaller database, there are two ways you can take. If you've never signed up for Truecaller, simply unlisting your number from a website will do. But if you have a Truecaller account, you'll have to deactivate it to be unlisted. And that's one of the biggest downsides. In order to delist your number from Truecaller, you'll have to stop using the app.

Truecaller says that they'll unlist your number 24 hours after you've deactivated your account. But that's not always reliable. Ask your friends to check if you're showing up in Truecaller after a couple of days. If your number keeps showing up, try Unlisting it from their website.
