The Service may contain links to other sites that are not owned or controlled by us. We are not responsible for the privacy practices of such other sites.
Personally identifiable information means information that can be used to identify you as an individual, such as:
If you provide personally identifiable information to us, either directly or through a reseller or other business partner, we will:
We may use your personal information to build statistical models relating to human memory and behavior, and to develop and train algorithms for efficient memorization. We may publish or otherwise redistribute these models and algorithms. We will take reasonable efforts to ensure that these models and algorithms do not disclose your personal information (for example, by revealing what words were studied at what times with sufficient granularity to de-anonymize a particular user).
We may send email to you, both to promote our products and services and to provide necessary information relating to your use of the Service (for example, to reset a forgotten password). You can opt out of promotional emails by notifying us by email, or by using an "unsubscribe" link in the email if one is present. You can opt out of all emails by closing your account. If you close your account, then you will no longer be able to use the Service.
A cookie, browser local storage, browser indexed database, or other similar mechanisms (collectively, "Storage") are small pieces of information stored on a user’s computer for record-keeping purposes. We use Storage on this site. We link the information we store in Storage to personally identifiable information.
We may use both session ID cookies and persistent cookies. A session ID cookie expires when you close you browser. A persistent cookie remains on your hard drive for an extended period of time. You can remove persistent cookies by following directions provided in your Internet browser’s “help” file.
For example, we may use a cookie to distinguish between registered and unregistered users of the Service, to gauge the effectiveness of our marketing compaigns, and to store information relating to tasks that you are performing in the Service.
We may employ a software technology called clear gifs, that helps us better manage content on our site by informing us what content is effective. Clear gifs are tiny graphics with a unique identifier, and are used to track the online movements of Web users. We may tie the information gathered by clear gifs to our customers’ personally identifiable information.
We may use clear gifs in our HTML-based emails to let us know which emails have been opened by recipients. This allows us to gauge the effectiveness of certain communications and the effectiveness of our marketing campaigns. If you would like to opt out of these emails, please see “Choice and Opt-Out.”
We reserve the right to modify this privacy statement at any time, so please review it frequently. If we make material changes to this policy, we will notify you here, by email, or by means of a notice on our home page.
