Oh - we were not aware the Caplaz website link is no longer active.
But, the company has other products on Google Play
.(Although the website links on Google Play go to the same address as our page...)
The developer does have a Light Illusion email account, so you can try that: firstname.lastname@example.org
However, as the development is 3rd party, we actually do not know development info, etc.
But, I do think all Google Play apps can be moved between phones, as they link to the Google Play account, not the hardware?
Google Play must have such info somewhere?
