1. What Data We Get
We collect certain data from you directly, like information you enter yourself, data about your consumption of content, and data from third-party platforms you connect with KRYZA. We also collect some data automatically, like information about your device and what parts of our Services you interact with or spend time using.
1.1 Data You Provide to Us
We may collect different data from or about you depending on how you use the Services. Below are some examples to help you better understand the data we collect.
When you create an account and use the Services, including through a third-party platform, we collect any data you provide directly, including:
Account Data In order to use certain features (like accessing content), you need to create a user account which requires us to collect and store your email address, password, and account settings. To create an instructor account, we collect and store your name, email address, password, and account settings. As you use certain features on the site, you may be prompted to submit additional information including occupation, government ID information, verification photo, date of birth, race/ethnicity, skill interests, and phone number. Upon account creation, we assign you a unique identifying number.
Profile Data You can also choose to provide profile information like a photo, headline, biography, language, website link, social media profiles, country, or other data. Your Profile Data will be publicly viewable by others.
Shared Content Parts of the Services let you interact with other users or share content publicly, including by posting reviews about content, asking or answering questions, sending messages to students or instructors, or posting photos or other work you upload. Such shared content may be publicly viewable by others depending on where it is posted.
Educational Content Data When you access content, we collect certain data including which courses, assignments and quizzes you’ve started and completed; content purchases and credits; subscriptions; completion certificates; your exchanges with instructors, teaching assistants, and other students; and essays, answers to questions, and other items submitted to satisfy course and related content requirements. If you are an instructor, we store your educational content which may contain data about you.
Student Payment Data If you make purchases, we collect certain data about your purchase (such as your name, billing address, and ZIP code) as necessary to process your order and which may optionally be saved to process future orders. You must provide certain payment and billing data directly to our payment service providers, including your name, credit card information or in case of cryptocurrency payment, public key of your wallet address, billing address, and ZIP code. We may also receive limited information, like the fact that you have a new card and the last four digits of that card, from payment service providers to facilitate payments. For security, KRYZA does not collect or store sensitive cardholder data, such as full credit card numbers or card authentication data.
Data About Your Accounts on Other Services
We may obtain certain information through your social media or other online accounts if they are connected to your KRYZA account. If you login to KRYZA via Facebook or another third-party platform or service, we ask for your permission to access certain information about that other account. For example, depending on the platform or service we may collect your name, profile picture, account ID number, login email address, location, physical location of your access devices, gender, birthday, and list of friends or contacts.
Those platforms and services make information available to us through their APIs. The information we receive depends on what information you (via your privacy settings) or the platform or service decide to give us.
If you access or use our Services through a third-party platform or service, or click on any third-party links, the collection, use, and sharing of your data will also be subject to the privacy policies and other agreements of that third party.
The data listed above is stored by us and associated with your account.
1.2 Data We Collect through Automated Means
When you access the Services (including browsing content), we collect certain data by automated means, including:
System Data Technical data about your computer or device, like your IP address, device type, operating system type and version, unique device identifiers, browser, browser language, domain and other systems data, and platform types.
Usage Data Usage statistics about your interactions with the Services, including content accessed, time spent on pages or the Service, pages visited, features used, your search queries, click data, date and time, referrer, and other data regarding your use of the Services.

We use tools like cookies, web beacons, and similar tracking technologies to gather the data listed above. Some of these tools offer you the ability to opt out of data collection.
2.1 Cookies and Data Collection Tools
2.2 Why We Use Data Collection Tools
KRYZA uses the following types of Data Collection Tools for the purposes described:
Strictly Necessary: These Data Collection Tools enable you to access the site, provide basic functionality (like logging in or accessing content), secure the site, protect against fraudulent logins, and detect and prevent abuse or unauthorized use of your account. These are required for the Services to work properly, so if you disable them, parts of the site will break or be unavailable.
Functional: These Data Collection Tools remember data about your browser and your preferences, provide additional site functionality, customize content to be more relevant to you, and remember settings affecting the appearance and behavior of the Services (like your preferred language or volume level for video playback).
Performance: These Data Collection Tools help measure and improve the Services by providing usage and performance data, visit counts, traffic sources, or where an application was downloaded from. These tools can help us test different versions of KRYZA to see which features or content users prefer and determine which email messages are opened.
Advertising: These Data Collection Tools are used to deliver relevant ads (on the site and/or other sites) based on things we know about you like your Usage and System Data (as detailed in Section 1), and things that the ad service providers know about you based on their tracking data. The ads can be based on your recent activity or activity over time and across other sites and services. To help deliver tailored advertising, we may provide these service providers with a hashed, anonymized version of your email address (in a non-human-readable form) and content that you share publicly on the Services.
Social Media: These Data Collection Tools enable social media functionality, like sharing content with friends and networks. These cookies may track a user or device across other sites and build a profile of user interests for targeted advertising purposes.

- Who We Share Your Data With
We share certain data about you with instructors, other students, companies performing services for us, KRYZA affiliates, our business partners, analytics and data enrichment providers, your social media providers, companies helping us run promotions and surveys, and advertising companies who help us promote our Services. We may also share your data as needed for security, legal compliance, or as part of a corporate restructuring. Lastly, we can share data in other ways if it is aggregated or de-identified or if we get your consent.
- With Your Instructors: We share data that we have about you (except your email address) with instructors or teaching assistants for educational content you access or request information about, so they can improve their content for you and other students. This data may include things like your city, country, browser language, operating system, device settings, the site that brought you to KRYZA, and your activities on KRYZA. If we collect additional data about you (like age or gender), we may share that too. We will not share your email address with instructors or teaching assistants.
- With Other Students and Instructors: Depending on your settings, your shared content and profile data may be publicly viewable, including to other students and instructors. If you ask a question to an instructor or teaching assistant, your information (including your name) may also be publicly viewable..
- With Service Providers, Contractors, and Agents: We share your data with third-party companies who perform services on our behalf, like payment processing, fraud and abuse prevention, data analysis, marketing and advertising services (including retargeted advertising), email and hosting services, and customer services and support. These service providers may access your personal data and are required to use it solely as we direct, to provide our requested service.
- With KRYZA Affiliates: We may share your data within our corporate family of companies that are related by common ownership or control to enable or support us in providing the Services.
- With Business Partners: We have agreements with other websites and platforms to distribute our Services and drive traffic to KRYZA. Depending on your location, we may share your data with these partners.

- With Analytics and Data Enrichment Services: As part of our use of third-party analytics tools like Google Analytics and data enrichment services like ZoomInfo, we share certain contact information, Account Data, System Data, Usage Data (as detailed in Section 1), or de-identified data as needed. De-identified data means data where we’ve removed things like your name and email address and replaced it with a token ID. This allows these providers to provide analytics services or match your data with publicly-available database information (including contact and social information from other sources). We do this to communicate with you in a more effective and customized manner.
- To Administer Promotions and Surveys: We may share your data as necessary to administer, market, or sponsor promotions and surveys you choose to participate in, as required by applicable law (like to provide a winners list or make required filings), or in accordance with the rules of the promotion or survey.
- For Advertising: If we decide to use an advertising-supported revenue model in the future, we may use and share certain System Data and Usage Data with third-party advertisers and networks to show general demographic and preference information among our users. We may also allow advertisers to collect System Data through Data Collection Tools (as detailed in Section 2.1), to use this data to offer you targeted ad delivery to personalize your user experience (through behavioral advertising), and to undertake web analytics. Advertisers may also share with us the data they collect about you. To learn more or opt out from participating ad networks’ behavioral advertising, see Section 6.1 (Your Choices About the Use of Your Data) below. Note that if you opt out, you’ll continue to be served generic ads.
- For Security and Legal Compliance: We may disclose your data to third parties if we (in our sole discretion) have a good faith belief that the disclosure is:
- Permitted or required by law;
- Requested as part of a judicial, governmental, or legal inquiry, order, or proceeding;
- Reasonably necessary as part of a valid subpoena, warrant, or other legally-valid request;
- Required to detect, prevent, or address fraud, abuse, misuse, potential violations of law (or rule or regulation), or security or technical issues; or
- Reasonably necessary in our discretion to protect against imminent harm to the rights, property, or safety of KRYZA, our users, employees, members of the public, or our Services.
- During a Change in Control: If KRYZA undergoes a business transaction like a merger, acquisition, corporate divestiture, or dissolution (including bankruptcy), or a sale of all or some of its assets, we may share, disclose, or transfer all of your data to the successor organization during such transition or in contemplation of a transition (including during due diligence).
- After Aggregation/De-identification: We may disclose or use aggregated or de-identified data for any purpose.
We use appropriate security based on the type and sensitivity of data being stored. As with any internet-enabled system, there is always a risk of unauthorized access, so it’s important to protect your password and to contact us if you suspect any unauthorized access to your account.
KRYTA takes appropriate security measures to protect against unauthorized access, alteration, disclosure, or destruction of your personal data that we collect and store. These measures vary based on the type and sensitivity of the data. Unfortunately, however, no system can be 100% secured, so we cannot guarantee that communications between you and KRYZA, the Services, or any information provided to us in connection with the data we collect through the Services will be free from unauthorized access by third parties. Your password is an important part of our security system, and it is your responsibility to protect it. You should not share your password with any third party, and if you believe your password or account has been compromised, you should change it immediately and contact our Support Team with any concerns.
