Most people don't want to think about ageing, but using FaceApp to age yourself and show your online friends has gone viral.

What some users may not know is that they are giving up a lot more information than they bargained for in exchange for a couple of laughs and likes on their post.

It has been discovered that FaceApp's terms and conditions of service are more all-encompassing than some people are comfortable with.

Troy Mclennan, CEO and President of HUB Technology Solutions, says he has trouble trusting an application like this.

Mclennan says, "You have to really think carefully about the reason why you are doing that. ... Think about the implications of what your image, your name, linked to your Facebook profile and all that information can mean to someone who wants that information. ... If you are comfortable with that, then use it."

For those that are not comfortable with a company owning their likeness - just like Mclennan - should be a little bit wary.

"I don't trust Facebook and I am not a conspiracy theorist."

Mclennan says, "It's their track record of giving your data to anyone they seem to feel fit will pay for it. They're not telling you about what they're doing with your data ... and that makes me extremely uncomfortable.

"Let's use FaceApp as an example. By using it, you're agreeing to the terms and conditions that you probably click through rather quickly. ... By doing that you are granting Facebook a perpetual, irrevocable, nonexclusive, royalty-free, worldwide, fully-paid, transferrable, sub-licensable license to use that data - which is your face and rendering of your image - any way that they choose fit forever and ever."

By using FaceApp and Facebook in tandem - using FaceApp to modify your picture and posting it to Facebook - you are giving both platforms access to your information.

For those that have used the application and are now trying to backtrack, Mclennan says it isn't that easy: "Once you've agreed, that's it."

Users can be more cautious in the future Mclennan says, "You can go through your security settings on those apps, such as Facebook, and do everything you can to make your profile as private as possible and try to mitigate any potential risks by doing that. And going forward, in the future, be very careful about what you agree to in some of these add-ons."

Using social media, on all platforms, can be used safely and with discernment.

Mclennan says, "Every time you post on social media - I always post with the assumption that anyone in the world can read this information that I am posting or see this information. I only put stuff on social media that I am comfortable with sharing with every single person in the world. That's my simple rule in deciding to post information or not."

"Information I would consider to be my own business does not go on those platforms."
