What will happen to PHPStorm after the end of the subscription?

Question

phpstorm

Less than a year ago, I purchased a personal phpstorm license. I read it beforehand and, it seems, I realized that if the subscription ends, I will have the version that was at that time, which would suit me perfectly. The editor recently added:

Your PhpStorm subscription expires on 02/29/2017. After this date you will no longer be able to use PhpStorm 2016.3.2

Which, as it were, means the inability to use the editor after 02/29/2017. I clarified this point in 2 different online software stores, in both they told me that the program would stop working.
I go here , there is a paragraph:

By purchasing an annual subscription. You immediately receive a backup perpetual license for the current version. You can continue to use this license if you decide not to renew your subscription after one year.

Question : how will the editor behave after the end of the subscription? I don’t see any backup perpetual license in the account, only the main one.

Answer 1

The program works for about a week, reminding you that it's time to renew the subscription, then it turns off.
But you can download the previous version (the one that came with the purchase of the subscription) and use it without upgrading.

Answer 2

It happens that there is no money on the card that is tied to the subscription at the time of debiting, in which case a letter from the JetBrains Team comes containing:

Dear Roman,
This is a friendly reminder that the next payment date for your subscription is approaching on April 01, 2017.
We hope you enjoy using JetBrains products and will consider renewing your subscription: renew online.
The subscription requiring payment include:
1 × All Products Pack
What happens if I don't renew?

But if you click on "What will happen if I do not renew?", then you will be thrown to the page: What is perpetual fallback license? , where it is shown in detail with pictures and examples how the license will behave:
