automatic license renewal at 12 months at a price of 49.99 €

bonjour,

I have a proposal for € 20.99 for acronis cyber protect home office,
 because apparently there is no longer a perpetual license.

the proposal stipulates at the end of 12 months the automatic change to 49.99 €.
(they are crazy about his Gauls).

my question :
what happens when at the end of the year there is a minimum price proposal.
what happens to automatic renewal.
all is fuzzy
can you have some clarification.

merci a vous.

thank you
