Is it possible to export subscribers?

Hello:

I’m curious if there is anyway to export the subscribers collected on webpushr? For example, if I wanted to host my own in house push service for my site in the future. Could I export my subscribers to this service in some way?

Note - completely happy with the free service. Thank-you for that. I am however curious as to whether or not subscribers can be exported and migrated to a in house solution.

Thanks for any information you can provide.
