By popular demand, as of version 7.9.5, Contacts Sync now gives you the option to purchase an upgrade that grants lifetime access to premium features, rather than a subscription. Subscriptions will continue to be offered, at a discounted price to the lifetime access upgrade.
Offering subscriptions allows Contacts Sync to improve more rapidly over time, and to more effectively maintain the app so it continues to work well.
