(Our policy has never changed.*)
In general, our service automatically gathers certain usage information like the numbers and frequency of visitors to different pages on our site, browser type, and the date and time of your request. We only use such data in the aggregate. This collective data helps us improve our site.
To prevent abuse, our servers also automatically record the IP address of visitors and the frequency of visits to specific URLs.
We will ask you for information about your interests so you can take advantage of the interactivity of the online medium, but you may always choose to respond or not and your answer is not stored on our computer. It is placed on a cookie on your computer. That cookie will also track information to help guide your experience, for example, which words you want to review.
If you send an e-mail to us, we may keep your address as appropriate for follow-up. We will not send you junk mail or willfully provide your address to third parties.
* In August 2017 we stopped using cookies on new pages, but we're not changing our policy that permits them since the old pages that use them are still accessable. Also, some functionality was sacrificed with the cookies and if enough users ask that the functionality be moved into the new pages, not changing our policy will permit us to do that without having to notify everyone of the change. In that event, this footnote will change.
