You're able to use SpinOffice CRM Limited version for as long as you want until you have reached a storage of 50 items added manually. Mass import of contacts (Excel, Apple Contacts or social media) and incoming emails do not count as an item.

You’ll get a notification when you’ve reached the storage limit and you’ll have to upgrade to SpinOffice Pro in order to add more items. 

Upgrading your account will give you unlimited storage of all data, full email integration, daily backups, support and more. Find more information about all features and prices.
