Thank you for posting in English. It is nice to hear about your new project.
Geodirectory allows for some automated collection of data from Yelp or Facebook, but only one record at time.
There are functions for import of listing data and images and export of listing data.
I recommend you proceed with an attempt to import your data. If you do not already have lat/lon coordinates or complete address data, you might consider setup of a CPT without address so that you can import the data you have.
Geodirectory retrieves the information on the web to complete the file with
Description + Screenshot + Meta title + favicon + etc
Does this function exist on this plug in?
Is there an application to recover it?
No, there is not a feature for this, if I understand correctly. There is not a feature that will scrape sites to retrieve data in that way.
If you need hands on help with setup of your site I recommend you approach an expert for a concierge service, so that you can get your new directory up and running quickly.

You can create a new CPT and then go to GD > general > general tab > Select CPT to disable physical location
All listings in a CPT need addresses, or none. You cannot mix listings with and without addresses in the same CPT.
