How long before an inactive account is deleted?

Pug

I am not able to login for a long period of time and I am a free player. How many days of inactivity do I have before my account gets deleted?

I am on Server S7, user name "pugdune".
I started being inactive in Middle of Feb but can only rejoin the game in late April.
I hope I can still come back to play on my free account in April.
Thus I was wondering at what point in time do you clear out free, inactive accounts? after how long do you do that?
