We want to take this opportunity to assure you that we do not collect, use or share personal information. Please take a moment to look through our privacy terms and please don't hestiate to contact us with any questions.

Privacy Policy

This website is operated by Montessorium, LLC (referred to herein as "Montessorium","us" or "we"). This Privacy Policy (“Privacy Policy” or “Policy”) explains what information we collect about visitors and subscribers to this website and purchases or users of our mobile apps and services (together referred to as "Users" or "You") and how we use this information. This Privacy Policy does not cover collection or use of information by third parties or linked sites, which Montessorium does not control, own or manage. 

The privacy of the Users is important to us. We support the goals set forth by oversight laws and bodies such as the Children's Online Privacy Protection Act of 1998 (COPPA), the Center for Media Education (CME), the Children's Advertising Review Unit (CARU) of the Council of Better Business Bureaus and other organizations devoted to providing online safety and privacy for children, households, parents and schools. 

We design and operate our technology and services with our Users’ protection and privacy in mind. This Privacy Policy outlines the types of information we gather when Users access this website, our mobile apps, technology and services, as well as some of the steps we take to safeguard it against unauthorized use. 

For purposes of this Policy, "Personally Identifying Information" shall hereby mean information which is identifiable to You, including, e-mail, name and address; "Anonymous Information" shall hereby mean information which does not enable identification of an individual user.  Additionally, Anonymous Information means “aggregate” and “de-personalized” information, which is data Montessorium collects about the use of Montessorium’s services and products, from which any personally identifiable data has been removed.

Data Collection 

Montessorium does not routinely collect Personally Identifying Information from Users. We may make use of a standard feature found in browser software, called a "cookie", to assign each visitor a unique, random number. Cookies allow us to track the pages on this site visited by Users and to collect other statistical information. Using cookies helps us to deliver a more personalized service to our Users and to improve our services. We may further use cookies to monitor potential fraud and abuse of the accounts or use which is not in accordance with the Terms of Use. It is Your choice whether to accept or reject cookies and You can set your browser to reject cookies altogether or to reject Montessorium’s cookies in particular or to delete these cookies. However, if You choose to reject cookies or delete them, it may limit some of the functionalities available or effect your experience with the services. 

Montessorium does not knowingly collect or maintain Personally Identifying Information from any person under the age of 18 ("Minors"). Minors may not use this website without parental consent. If we learn that any personal information about any Minor has been collected without parental consent, then we will take reasonable steps to delete any such information.

A note to educators: Please get permission from the minors’ parents/legal guardians before allowing minors to use the Montessorium website or products or to send any e-mail to us or to anyone on the Internet. 

Montessorium may use the collected information about Your browser, operating system or other technical details of Your usage to improve Your experience with our services. Montessorium may further use the collected Anonymous Information (non-identifying information) about usage patterns, time of usage and form of usage, to improve the experience and to be able to improve Montessorium's offering of our services to users. 

Montessorium reserves the right to use and disclose, in its sole discretion, Anonymous Information about Visitors and Users to third parties, including advertisers and partners, in order to target advertisement and information presented to You. Anonymous Information disclosure in this regard may also include selective disclosure of search terms and socio-demographic information, as long as it does not explicitly reveal Personally Identifying Information. 

Montessorium may use tools or third party analytical software to automatically collect and use certain Anonymous Information that does not directly enable Montessorium to identify you.

Montessorium may use and disclose to Montessorium’s partners and contractors the collected Anonymous Information for purposes of analyzing usage of its products, services, advertisement serving, managing and providing Montessorium to further develop other Montessorium services and products.

You recognize and agree that the analytics companies utilized by Montessorium may combine the information collected with other information they have independently collected from other services or products relating to your activities. These companies collect and use information under their own privacy policies.

Montessorium or third parties operating the ad serving technology may use demographic and location information as well as information logged from your hardware or device to ensure that appropriate advertising is presented within the products and services.

However, search history information may be shared with third parties only in its anonymous form (i.e. the Anonymous Information) and without disclosing any Personally Identifying Information which is associated with or related to this information. 

Legally Required Disclosure
