Data & Privacy

Privacy Policy

This policy explains what information Mimir Nest processes and how your data is handled when you use the website.

Effective Date: August 30, 2026

1. Overview

Mimir Nest is an open-source student platform. The project is designed with the objective of minimizing unnecessary data collection, allowing students to access utilities without subscription barriers or commercial tracking. This policy details what data may be processed when you interact with the website at mimirnest.vercel.app.

Please note that while the website's educational content and frontend application code are publicly available and open-source, your private account details, bookmarks, and learning progress are stored securely on our private backend infrastructure and are never made public.

2. Information We Collect

You can browse our public educational content (including Projects, Courses, DSA checklists, System Design articles, and Email Perks) completely without creating an account. Creating an account is entirely optional.

Account and Profile Information

If you choose to create a Mimir Nest account, we collect standard credentials:

  • Basic Account Information: Your name and email address when you register using our signup form.
  • Authentication Provider Info: If you use Google Sign-In, we receive authentication details from Google (email address, name, and profile picture/avatar URL) to create and log you into your Mimir Nest account.
  • Saved Features and Progress: We store bookmarks and learning progress details that you choose to save when logged into your account.

Contact Communications

If you voluntarily write to us at mimirnest@gmail.com, we process your email address and any message content to address your inquiry.

Analytics Information

Mimir Nest integrates Google Analytics (measurement ID G-S9BCG5CN4G). This service collects telemetry concerning how users access the site, including page views, request timestamps, approximate geolocation (derived from IP addresses), browser types, and system configurations.

Technical / Hosting Information

Our hosting and backend infrastructure automatically processes standard web server logs on every request. This includes your IP address, browser user-agent header, request pathways, and access timestamps. This information is processed to maintain performance, stability, and secure the service from unauthorized access or network abuse.

3. Cookies and Local Storage

Mimir Nest uses standard cookies and browser local storage to enable essential features, persist layout preferences, and measure traffic performance:

Authentication Cookies

If you choose to register or log in, we set an HttpOnly session cookie (named token) containing a JSON Web Token (JWT). This cookie is protected from client-side script access, securing your authentication session against cross-site scripting vulnerabilities.

Preference Cookies

We use a standard client-side cookie (named sidebar:state) to persist the open/close state of the navigation sidebar across page loads.

Analytics Cookies

Google Analytics sets standard telemetry cookies to compile reports on site traffic and page interaction metrics.

Local Browser Storage

To support offline/local utilities without requiring an account, Mimir Nest stores configurations directly inside your browser using the localStorage API:

  • Pomodoro Timer Settings & Stats: Saves active timer configurations, completed focus counts, and streak histories.
  • Placement DSA SOLVED logs: Saves checked statuses representing which questions you have solved locally.

This stored browser information remains entirely client-side and is never transmitted back to Mimir Nest servers or transferred to any third-party services. You can clear this data at any time by utilizing your browser options to clear site storage cache.

4. How We Use Information

We use the collected information for the following specific purposes:

  • Authentication and Account Management: Creating your account, verifying your identity, managing your session, and providing access to personalized features.
  • Saving Preferences and Progress: Persisting your bookmarks and educational progress inside your account, or locally via browser storage/cookies if you are browsing without an account.
  • Operating and Securing the Service: Diagnosing errors, resolving technical issues, preventing security incidents, and protecting against network abuse.
  • Improving Performance: Monitoring website speed, layout responsiveness, and auditing traffic metrics.
  • Correspondence: Responding to inquiries or privacy requests sent to our contact email.

5. Google Analytics

Google Analytics is a telemetry service provided by Google LLC. It leverages identifiers and cookies to compile reports on site traffic. Google's data handling is outlined in the Google Privacy Policy and How Google uses information from sites.

Important Implementation Disclosure

Google Analytics script loads and runs immediately upon page access. Mimir Nest does not currently feature a cookie consent banner. If you do not wish to be tracked, you can block the script by utilizing client-side privacy extensions (like uBlock Origin) or configuring your browser to block tracking scripts.

6. Third-Party Services

The following service providers process information necessary to host, secure, authenticate, and analyze our platform:

7. Data Sharing

Mimir Nest does not sell, barter, lease, or distribute your personal information to advertising agencies, data brokers, or third-party marketing services. Data processing is strictly limited to the infrastructure and integration partners (Vercel, Neon, and Google) needed to run, secure, authenticate, and analyze the website performance.

8. Data Retention

Account and Progress Data

Personal information, bookmarks, and learning progress stored on our backend database are retained for as long as your account remains active or as necessary to provide the platform services.

Local Browser Data

Information stored in your browser's localStorage or client-side cookies is retained indefinitely until you choose to clear your browser cache or site storage cache.

Contact Communications

Any email correspondence sent to mimirnest@gmail.com is retained as long as necessary to address the inquiry and maintain proper record of communication.

Infrastructure and Telemetry Logs

Retention durations of standard web server logs and Google Analytics events are governed by the hosting and analytical platform lifecycle configurations (Vercel and Google LLC).

9. Data Security

All Mimir Nest traffic is encrypted using HTTPS. We also implement static analysis security testing (CodeQL scans) on codebase upgrades to prevent vulnerability introduction. However, no transmission method over the internet or browser storage mechanism is completely secure, and we cannot guarantee absolute security.

10. Your Choices and Rights

You can manage your data using the following options:

  • Clear Local Storage and Cookies: You can clear your browser storage cache and cookies to reset Pomodoro logs, local DSA checkmarks, and the sidebar layout preference.
  • Account Deletion and Data Management: You can manage or delete your bookmarks and learning progress directly inside your account settings when logged in. To delete your account completely, please contact us at mimirnest@gmail.com.
  • Block Telemetry: Install tracker blockers (e.g., uBlock Origin) or block cookies in your browser settings to prevent Google Analytics scripts from running.
  • Privacy Rights: Depending on your jurisdiction, you may have statutory rights regarding your personal information (such as requesting access, deletion, porting, or correction). To send a formal request, email us at mimirnest@gmail.com.

11. Children's Privacy

Mimir Nest is intended for high school and college students, and the platform is not specifically directed at children under the age of 13. If we become aware that we have collected personal data from a child under 13 in circumstances where applicable law requires parental consent, we will take immediate steps to remove it.

12. Changes to this Policy

We may update this Privacy Policy from time to time to reflect changes to the website, our practices, or applicable requirements. When we make changes, we will update the effective date shown at the top of this page.
