Good morning,

 

I need some help about questions. English is not my native language but I am living in UK , hope you can understand me (I am French).

I work at a hotel and I have met someone and kept contact with him. We talked several times through messages on a mobile app. The app has encrypted servers. 

But I got scared of him. I have 2 main questions:

 

- can he find my IP address during this kind of conversations?

and

- if he were using a wifi network, does anyone using the same network could intercepted our conversation and therefore, help him to find my home?

 

I sent messages from my home, using my wifi network. 

I am sooo bad in informatics, thanks for your help.

What type of smartphone do you use and what app did you use?

 

You are scared that he finds where you live?

depends, what type of communication did you use? If he did not have control of the servers, it is unlikely but not impossible.

if he were using a wifi network, does anyone using the same network could intercepted our conversation and therefore, help him to find my home?

possibly, though most communications are encrypted. Therefore, for anyone else other than the person you communicated with to find out about your communication, they would have to break the encryption first - not typically an easy task.

Thanks for the replies. I use an IPhone 6s and I sent messages, pictures and voice recorders through Hellotalk. I don't know how this app works, I sent them an email and they told their servers are encrypted. I do not know what that means.

Sorry, I'm not familiar with HelloTalk. I took a look at their site, but it doesn't tell me much about anonymity.

Encrypted means that the user data stored on their servers is scrambled with a password to protect it from unauthorized access. It doesn't answer your question. I would ask them if the app connects directly to other users or if both users communicate with one of their servers. That should let us know if your IP address could have been found.

I would say your connecting to a server with SSL.

I sent them an email asking what you said. I am just waiting for their reply.
If I understood well... If the server is SSL so we are talking directly from a device to another device without any intermediary proxy or something.

Not necessarily, SSL just means a secure connection. It could be device to device, or device to server to device.

I'm quite certain device to server to device.

I would be more concerned with the GPS location sharing. http://www.fluentin3months.com/hellotalk-review/

(1) Smileys and other features you’d expect from a good chat program, like notifications of new messages, GPS location sharing, text size settings.

(2) As with Whatsapp, you can share your GPS location to make it easier to find language partners nearby.
