You ask many good questions that we need to be much clearer in our communication about – so they don’t need to be asked!
1 – What happens when the 30 day Premium period ends? Nothing, really. Premium features are no longer accessible, you revert automatically to the free version. No need for new downloads or anything. AxCrypt mostly works as usual, but without the perks of Premium.
2 – What happens with 256-bit encrypted files when the Premium period ends? Nothing, really. Of course you can still open them! We’ll never lock you out of your data because of a discontinued subscription. They will open normally, and remain 256-bit until modified and re-encrypted, in which case they will use 128-bit encryption instead.
3 – What happens with passwords saved in the Password Manager when the Premium period ends? Nothing, really. Of course you can still read them! We’ll never lock you out of your data because of a discontinued subscription. However, you can no longer update, add or delete new passwords. (You didn’t ask, but this was a good place to answer the question anyway!)
