CogSci Apps Corp. is the developer of Hook Productivity software, and is committed to protecting and respecting your privacy. The general privacy policy for this website and app is at Privacy Policy – CogSci Apps®.

Hook is an app, not a SaaS, that specializes in bookmarking your information and helping you navigate your data.

The following explains how CogSci Apps Corp. relates to your data, which is basically that CogSci Apps Corp. has no visibility of the data with which Hook transactions, nor does Hook send your bookmark information to servers.

Hook data privacy information

Hook stores your bookmarks on your Mac in the ~/Library/Application\ Support/com.cogsciapps.hook/. You can sync your data across devices via iCloud, USB stick, a cloud service, or other means. Syncing is discussed in Sync Tab – Hook. See also How to Backup and Restore Hook Data – Hook. Either way, your synced data are not sent to our servers.

Bookmarking (links, hooks, etc)

When you bookmark something, Hook collects and stores the bookmark locally on your Mac. A bookmark consists of title and URL. Hook may also add meta-information such as the date the bookmark was created. Bookmarking operations may be triggered by:

Hook also collects and locally stores information for bookmarking, such as to connect two bookmarks together (“hooking them together”).

Again, CogSci Apps does not itself send this information to its servers but you are free to share or sync it yourself wherever you want (it’s your data).

Other information

Hook enables you to create .hook files ( Make Hook File and various other files (Hook to New). You may keep those files on your Mac or store those files wherever you like (such as servers) — that is your business and not under the control of Hook either. For instance, if you do Hook to New > OmniFocus item and your OmniFocus data are synced via The Omni Group, then obviously those items will be sent to servers, but those data are not sent by Hook, or are we involved in or responsible for those servers.

Internet connections

  • Hook may connect with its license server to register and verify/validate your Hook license (the license key you purchased and that may entitle you to a Hook product). This does not contain your email address. Nor does it contain any information about you or your device other than license related information.
  • If you use “Quick Look” in Hook, Hook may connect to the web to show you a version of the web page you are looking at.
  • accessing Hook documentation via Hook involves connecting to
  • If you check for software updates in Hook (automatically or manually), then Hook may connect with a service such as Microsoft App Center to verify whether an update is available for you.
