Our Advanced Desmos Tools may be used by third party providers of educational services, such as schools, school districts, school systems, teachers or other instructors (collectively referred to as “Schools”).
When Desmos contracts with a School to provide Services including Advanced Desmos Tools to students of the School (“Students”), we may have access to Student Data (defined below). We consider Student Data to be highly confidential and our processing of Student Data is governed by our Student Data Privacy Statement, our Terms of Service and/or our written agreements with the applicable School.
Please see our Student Data Privacy Statement for additional information about how we collect and use Student Data gathered during the provision of the Service to Schools.
If you represent a School in the United Kingdom or European Economic Area, you can review our standard, template DPA with attached SCCs here. If the School would like to enter into that DPA (and attached SCCs) with us, please send an email to privacy-gdpr@desmos.com, with the following information about the school: (i) name, (ii) address, (iii) telephone number, (iv) signatory name, (v) signatory title, and (vi) signatory email address, and (vii) domain name for staff and student email address account usernames. We will then send the school’s signatory a copy of the DPA for electronic signatures, and arrange for signature by Desmos’ authorized representative.
a. Personal Data You Disclose to Us. You can use many of our Services without registering for an account with Desmos. If you choose to create an account on the Service, or communicate with Desmos, you may provide to Desmos certain information by which someone could personally identify you, such as your name, email or unique username (“Personally Identifiable Information”), passwords and similar information used for authentication and account access (“Security Information”), as well as information about yourself such as your employment or level of schooling by which someone could not personally identify you (“Demographic Information”). When we link Security Information or Demographic Information to your Personally Identifiable Information, we treat all of it as Personally Identifiable Information. We also collect information (i) when you save or post content to the Service, (ii) if you expressly authorize us to access your device camera and photo roll to upload pictures to the Service, and (iii) and if you communicate with us via email or otherwise.
We refer to all of this data collectively as “Personal Data”. We may also collect limited Personal Data about you from a third party Internet site or service. For example, if you login to your Desmos account through Google or another authentication tool, or if you interact with Desmos on social media, we may collect the Personal Data you authorize that third party service to share with us, such as email address or name.
We do not knowingly collect: (i) exact geolocation data, (ii) behavioral data for advertising purposes, (iii) biometric / health data, or (iv) sensitive data, as defined under the General Data Protection Regulation (GDPR) (including, racial or ethnic origin, political opinions, religious or philosophical beliefs, or trade-union membership, and the processing of genetic data, biometric data for the purpose of uniquely identifying a natural person, data concerning health or data concerning a natural person's sex life or sexual orientation).
b. Usage Data. We automatically collect certain technical usage information when you use our Service (“Usage Data”).

Typically, this information is collected through log files, web beacons, browser cookies, or other device identifiers that may uniquely identify your browser or device. You may be able to set your web browser to refuse all cookies, and your mobile device to not provide your mobile device identifier. You may not be able to delete or disable cookies on certain mobile devices and/or certain browsers. For more information on cookies, please review the Desmos Cookie Policy or www.allaboutcookies.org. Remember, some features of our Service may not function properly if cookies or mobile device identifiers are not enabled. In addition, our Service may use third party analytics and bug tracking software (including, without limitation, Google Analytics and Bugsnag) to collect further Usage Data regarding the online usage patterns of our users and bugs in our Services. We may combine Usage Data with Personal Data in a manner that enables us to trace Usage Data to an individual user. If we do so, we will treat such combined data as Personal Data.
We do not authorize third party advertising networks or other third parties to collect information about your browsing behavior from our website for advertising purposes.
We use Personal Data and Usage Data (together, “User Information”) for a variety of business purposes described below. We process your Personal Data for these purposes in reliance on our legitimate business interests (“Business Purposes”), in order to enter into or perform a contract with you (“Contractual”), with your consent (“Consent”), and/or for compliance with our legal obligations (“Legal Reasons”). We indicate the specific processing grounds we rely on next to each purpose listed below.

The profile information we receive may vary depending on the social media provider concerned, but will often include your name and e-mail address.

We care about the security of your Personal Data and employ physical, administrative, contractual, and technological safeguards designed to preserve the integrity and security of all information collected through our Service. Access to information is limited (through user/password credentials and, in some cases, two factor authentication) to those employees who require it to perform their job functions. We use industry standard SSL (secure socket layer technology) encryption to transfer Personal Data. Other security safeguards include but are not limited to data encryption, firewalls, physical access controls to buildings and files, and employee training. In addition, we enter into contracts with all third-party entities or agents that participate in an onward transfer of Personal Data, and seek contractual security assurances from such third parties. You can help protect against unauthorized access to your account and Personal Data by selecting and protecting your password appropriately and limiting access to your computer and browser by signing off after you have finished accessing your account.
We will only keep your Personal Data for as long as it is necessary for the purposes set out in this Privacy Policy, unless a longer retention period is required or permitted by law (such as tax, accounting or other legal requirements). No purpose in this policy will require us keeping your Personal Data connected to your account for longer than 90 days past the termination of your account.
When we have no ongoing legitimate business need to process your Personal Data, we will either delete or anonymize it, or, if this is not possible (for example, because your Personal Data has been stored in backup archives), then we will securely store your Personal Data and isolate it from any further processing until deletion is possible.
