Software Updates included for one year with Essentials or Pro, subsequent updates require an Updates License

When you buy Hook (Essentials or Pro), you can use Hook for as long as you want. However, we cannot provide free updates for life. So, each paid license of Hook includes 12 months of updates. If you install a version of Hook that was released after your free update period has ended, Hook will ask you to downgrade to an older version or purchase an Updates License to get another year of updates.

Updates Licenses (renewals): When your initial 12-month license expires, you will be able to purchase an Updates License for 40% less than the then current regular (non-discounted) Hook price of that tier. ($11.99 for Pro at current prices, which works out to 3 cents a day.) Updates Licenses gives you access to another 12 months of software updates and continued priority technical support. But even if you don’t purchase an Updates License, you can continue to use your licensed copies of Hook indefinitely (it’s just that you will not be able to get updated versions until you purchase an Updates License).

Upgrading from Essentials to Pro

Owners of an Essentials license may upgrade from Hook Essentials to Hook Pro at a pro-rated price. E-mail us a copy of your Order confirmation number and license key, and we will send you information about this.

Lite mode (free, automatically kicks in after Trial expires)

When the Hook trial expires, Hook downgrades automatically to Hook Lite. In Lite mode, users can generate shareable email links (hook://email), but not links to other types of items (such as files or tasks). Lite mode users can use (click on and activate) as many links as they like. They can use links they previously created and any links received from others. However, most other features are disabled in Hook Lite. Please refer to the table above.
