Both Premium and basic users are subject to a file expiration policy. The files of basic members will expire after being inactive for 7 days. The files of Premium members will expire after being inactive for 30 days.
Both Premium and basic users of PDFescape can preserve a file in their accounts indefinitely by simply logging into your account and viewing the file once every 7 days (or 30 days for Premium members) as that will reset the expiration timer for that file.
These limits help us ensure that we can provide a free service to all users and aren't continuing to store files which are no longer needed. All file storage is subject to our terms of use (http://www.pdfescape.com/terms/) and privacy policy (http://www.pdfescape.com/privacy/).
