Cookie Policy

Vrenberg uses cookies, local storage, pixels, device identifiers, server logs, and similar technologies (collectively, “Tracking Technologies”) to operate, secure, maintain, analyze, and improve the Platform. These technologies are integral to how the Platform functions and how we deliver, protect, and enhance the educational experience.

Tracking Technologies help Vrenberg:

• Authenticate users and maintain active sessions across Platform features.
• Secure accounts and protect against unauthorized access, fraud, and abuse.
• Improve Platform performance, reliability, and responsiveness.
• Understand how users interact with features, tools, and educational content.
• Measure engagement, feature adoption, and usage patterns across the Platform.
• Support internal analytics, reporting, and research initiatives.
• Improve educational systems, adaptive learning, and the overall user experience.

Cookies are small text files placed on your device by a website. They may be “session” cookies, which are deleted when you close your browser, or “persistent” cookies, which remain on your device until they expire or you delete them. Other Tracking Technologies operate through similar mechanisms and serve comparable purposes. References to “cookies” throughout this policy include all Tracking Technologies unless otherwise specified.

Vrenberg uses the following categories of cookies and similar technologies. The specific cookies deployed may change over time as the Platform evolves, but they will serve the purposes described within these categories.

2.1 Essential Cookies

Essential cookies are required for the basic operation of the Platform. They enable core functionality such as user authentication, session management, account access, navigation between pages, and access to authenticated features. Without these cookies, the Platform cannot function as intended. Essential cookies are set automatically when you access the Platform and do not require separate consent.

2.2 Security Cookies

Security cookies protect the integrity and safety of the Platform, user accounts, and user data. They assist in detecting and preventing unauthorized access, credential abuse, session hijacking, cross-site request forgery, bot activity, and other security threats. Security cookies are necessary for the protection of the Platform and its users and remain active where permitted by applicable law.

2.3 Functional Cookies

Functional cookies enable enhanced features and personalization. They remember user preferences, display configurations, study mode selections, and other settings that improve the experience without being strictly necessary for core operation. Disabling functional cookies may cause certain Platform features to behave differently or lose personalized settings.

2.4 Performance Cookies

Performance cookies collect information about how the Platform operates, including page load times, error rates, resource utilization, and infrastructure metrics. This data is used to identify performance bottlenecks, optimize delivery, improve reliability, and ensure the Platform meets operational standards. Performance data is typically collected in aggregate form.

2.5 Analytics Cookies

Analytics cookies help Vrenberg understand how users interact with the Platform, which features are most used, how users navigate between pages and tools, and where users encounter difficulty or abandon workflows. This data informs product decisions, feature development, content improvements, and educational system refinements. Analytics data may be processed internally or through third-party analytics providers.

2.5.1 Google Analytics 4 and Google signals

Vrenberg uses Google Analytics 4 (provided by Google LLC) for product analytics. Google Analytics sets cookies (including _ga and _ga_*) and processes information such as IP address, device and browser identifiers, approximate location, pages viewed, referring source, and events you trigger on the Platform (for example, sign-up, starting a free trial, downloading the formula sheet, or completing a purchase). We have enabled the following Google Analytics features:

• Google signals — when a visitor is signed in to a Google account and has consented (in their Google account) to ads personalization, Google may associate the visitation information collected here with information from that Google account, including end-user location, search history, YouTube history, and data from sites that partner with Google, to enable cross-device measurement and aggregate audience insights.
• User-ID — when you are signed in to your Vrenberg account, we may transmit a non-identifying internal identifier to Google Analytics so that activity from the same person across devices and sessions can be reconciled.
• Granular location and device data— city-level location and device details derived from your IP address and request headers, used to power Google Analytics' location- and device-based reporting capabilities.

You can opt out of Google Analytics at any time using the Google Analytics Opt-out Browser Add-on, manage ads-personalization controls in your Google account, or block analytics cookies through the browser controls described in Section 6.

Certain Platform features may not function properly, may lose personalized settings, or may deliver a degraded experience if some categories of cookies are disabled. Essential and security cookies cannot be disabled without impairing core Platform functionality and account protection.

Tracking Technologies deployed on the Platform may collect the following categories of information:

• Session Activity: Login events, session duration, session frequency, and active usage periods.
• Feature Usage: Which Platform features, tools, and content areas you access, how frequently, and in what sequence.
• Navigation Behavior: Pages viewed, click paths, scroll depth, navigation patterns, and workflow completion rates.
• Device Information: Device type, operating system, screen resolution, hardware characteristics, and device identifiers.
• Browser Information: Browser type and version, language settings, installed plugins, and rendering capabilities.
• IP Address: Your Internet Protocol address, used for security, fraud prevention, geographic analysis, and infrastructure optimization.
• Approximate Geographic Region: General location derived from IP address data, used for analytics, compliance, and content delivery optimization.
• Referrer Information: The URL or source from which you navigated to the Platform.
• Access Timestamps: The date and time of each request, page load, and interaction event.
• Page Interactions: Click events, form interactions, input focus patterns, and element engagement metrics.
• Platform Performance Metrics: Page load times, rendering performance, API response latency, and client-side error events.
• Authentication and Security Events: Login attempts, session creation and expiration events, password reset requests, and security-related access patterns.

This information may be associated with your user account where permitted by applicable law and necessary for Platform functionality, security, analytics, or the purposes described in this policy and our Privacy Policy.

Vrenberg uses information collected through Tracking Technologies to continuously improve the Platform and the educational experience it delivers. Specific uses include:

• Improving Platform functionality, stability, and reliability.
• Optimizing performance, page delivery, and infrastructure efficiency.

Vrenberg may create aggregated, anonymized, de-identified, or statistical datasets derived from information collected through Tracking Technologies. Such datasets do not identify individual users and may be retained and used indefinitely for any legitimate business purpose, including but not limited to product improvement, research, analytics, benchmarking, reporting, and commercial applications. Aggregated, anonymized, de-identified, statistical, and derived datasets created by Vrenberg are owned exclusively by Vrenberg and do not constitute personal information.

Vrenberg integrates with third-party service providers to deliver, secure, and improve the Platform. These providers may deploy their own cookies, pixels, or similar Tracking Technologies on your device when you use the Platform. Third-party providers currently include, but are not limited to:

• Stripe: Payment processing, transaction security, and fraud prevention.

Third-party cookies and Tracking Technologies are governed by the respective privacy and cookie policies of those providers. Vrenberg does not control the cookie practices, data collection methods, or privacy policies of third-party services and is not responsible for their practices. We encourage you to review the privacy and cookie policies of any third-party services that interact with the Platform.

6.1 Cookie Consent

Where required by applicable law, Vrenberg will obtain your consent before placing non-essential cookies on your device. Consent mechanisms may include cookie banners, preference centers, or other tools presented when you first access the Platform or when material changes occur.

6.2 Managing Your Preferences

You can manage your cookie preferences through the following methods:

• Browser Controls: Most web browsers allow you to view, manage, block, and delete cookies through their settings. The specific steps vary by browser:
  • Chrome: Settings → Privacy and Security → Cookies and other site data
  • Firefox: Settings → Privacy & Security → Cookies and Site Data
  • Safari: Preferences → Privacy → Cookies and website data
  • Edge: Settings → Cookies and site permissions → Cookies and site data
• Local Storage: Browser developer tools or privacy extensions allow you to clear local storage and session storage data associated with the Platform.

6.3 Withdrawal of Consent

Where you have provided consent for non-essential cookies, you may withdraw that consent at any time by adjusting your browser settings, clearing cookies from your device, or contacting us at legal@vrenberg.com. Withdrawal of consent does not affect the lawfulness of processing that occurred before withdrawal.

6.4 Essential and Security Technologies

Essential cookies and security-related Tracking Technologies may remain active where permitted by applicable law, as they are necessary for the operation, protection, and integrity of the Platform. Disabling these technologies will impair core Platform functionality, including authentication, session management, and account security.

6.5 Do Not Track Signals

Some browsers offer a “Do Not Track” (DNT) signal. There is currently no universally accepted standard for how websites should respond to DNT signals. Vrenberg does not currently alter its data collection or Tracking Technology practices in response to DNT signals. This policy will be updated if industry-wide standards for DNT are adopted.

Information collected through cookies and similar Tracking Technologies may be transferred, assigned, or disclosed as part of a merger, acquisition, financing, reorganization, restructuring, bankruptcy, asset sale, or similar corporate transaction, subject to applicable law. In such events, the acquiring entity's use of your information will remain subject to this Cookie Policy or a policy providing at least equivalent protections.

Tracking Technologies evolve over time as web standards, browser capabilities, security requirements, and analytical tools advance. The specific cookies, technologies, and third-party providers described in this policy are illustrative rather than exhaustive. They represent the categories and types of technologies in use at the time of the most recent update.

Vrenberg may implement new cookies, modify existing cookies, adopt additional Tracking Technologies, or integrate new third-party services consistent with the purposes described in this policy. Such changes may occur as the Platform develops, new features are introduced, security requirements evolve, or operational needs change.

Updates to the specific technologies in use may occur without changing the fundamental purposes described in this policy. The categories described in this policy are intended to describe purposes rather than specific technologies, providers, or implementations. Where changes are material in nature or effect, they will be reflected in an updated version of this policy in accordance with the change procedures described below.

Vrenberg may update this Cookie Policy from time to time to reflect changes in our practices, the technologies we use, legal requirements, or for other operational, legal, or regulatory reasons. The “Last Updated” date at the top of this policy indicates when it was last revised.

Material changes will be communicated by posting the revised policy on the Platform with an updated date and, where required by applicable law or where we determine it appropriate, by notifying you through email or an in-platform notice. Your continued use of the Platform following the posting of an updated Cookie Policy constitutes your acknowledgment and acceptance of the changes.

We encourage you to review this policy periodically to stay informed about how Vrenberg uses Tracking Technologies.
