Hi!
Indeed on Android the export/import is not implemented yet; it requires additional permissions for the app + it's unclear to me how a person would copy an export to another smartphone at this moment, how would you do that? Via google drive or something?
Concerning the percentage: do you mean that you want to pay out only 90%? I never considered that use case, indeed, the Prizes try to total up to 100%. But your request is valid, I'll look into that, should not be too much work.
The text in the prizes is on my todo-list.
Thanks for your input, that's really valuable and appreciated!
