Privacy Policy

Last Updated: January 14, 2026

1. Introduction

Welcome to Argraide. We are committed to protecting your privacy and handling your data responsibly. This Privacy Policy explains how we collect, use, and safeguard your information when you use our Platform.

Our Core Privacy Principle: We practice data minimization by design. We collect only the information necessary to provide our services, and we never collect personal information from students.

2. Information We Collect

2.1 Teacher/Creator Accounts

For educators who create accounts, we collect:

  • Account Information: Email address, username, and password (encrypted).
  • Profile Information: Display name, profile picture (optional), and teaching areas.
  • Usage Data: Activities created, session information, and feature usage.
  • Payment Information: For Marketplace sellers, payment details are securely processed through Stripe. We do not store full payment card details.

2.2 Student Accounts (Zero-PII Architecture)

We do NOT collect personal information from students. Our student authentication system is designed to be completely anonymous:

  • Students are identified by randomly generated emoji sequences (e.g., šŸš€šŸ¦šŸ•).
  • No names, emails, phone numbers, or other identifying information is collected.
  • The only data associated with student accounts is learning progress and activity scores.
  • Teachers maintain their own private records mapping emoji codes to student namesā€”this data never touches our servers.

2.3 Automatically Collected Information

  • Technical Data: Browser type, device information, and operating system. IP addresses are NOT collected or stored (see Section 5.1).
  • Cookies: Session cookies for authentication and preferences. See Section 5 for details.

3. How We Use Your Information

We use collected information to:

  • Provide and improve the Platform's functionality.
  • Process Marketplace transactions and Creator payouts.
  • Facilitate Community Impact Grant donations to charitable organizations.
  • Communicate important updates about your account or the Platform.
  • Ensure security and prevent fraud.
  • Comply with legal obligations.

We do NOT:

  • Sell your personal information to third parties.
  • Use student data for advertising or marketing.
  • Share data with third parties for their marketing purposes.

4. Community Impact Grants & Charitable Donations

Argraide donates 1% of annual platform profits to charitable causes aligned with UN Sustainable Development Goals. Teachers vote annually to determine which SDGs receive funding. In connection with these donations:

  • Donations are made by Argraide on behalf of the global teaching community.
  • We may share aggregate, non-personal statistics about total donations and supported SDGs.
  • No personal information about individual Creators or students is shared with charitable organizations.

5. Cookies & Tracking

We use cookies for:

  • Essential Cookies: Required for authentication and core functionality.
  • Preference Cookies: Remember your settings (e.g., dark mode, language).
  • Analytics Cookies: Help us understand how the Platform is used to improve our services.

We do not use cookies for behavioral advertising or cross-site tracking.

5.1 Privacy-Hardened Analytics

We use PostHog for product analytics, configured in "Zero-PII Mode" with the following privacy protections:

  • No IP Address Collection: IP addresses are explicitly disabled and never stored.
  • Anonymous Identifiers Only: Users are identified solely by anonymous database UUIDsā€”never by name, email, or username.
  • Masked Session Recordings: All form inputs and screen text are masked in any session replays, appearing as asterisks (****).
  • No Copy-Paste Capture: Text that users copy or paste is never recorded.
  • Student Data Protection: For student accounts, we send only the role designation ("student")ā€”no usernames, school names, or any identifying information.

This configuration ensures that even in the event of a data breach at our analytics provider, no personally identifiable information about students could be exposed because it was never transmitted.

6. Children's Privacy & COPPA

Protecting children's privacy is paramount. Our Platform is designed to comply with the Children's Online Privacy Protection Act (COPPA) by not collecting personal information from children under 13.

For detailed information, please review our COPPA Compliance Statement.

7. Data Security

We implement industry-standard security measures to protect your data:

  • All data is encrypted in transit using TLS/SSL.
  • Passwords are hashed using secure algorithms.
  • Access to personal data is restricted to authorized personnel only.
  • Regular security audits and monitoring are performed.

8. Data Retention

We retain your information only as long as necessary to provide our services:

  • Active Accounts: Data is retained while your account is active.
  • Deleted Accounts: Personal data is deleted within 30 days of account deletion, except where retention is required by law.
  • Student Data: Automatically purged at the end of each school year or upon teacher request.

9. Your Rights

Depending on your location, you may have the right to:

  • Access the personal data we hold about you.
  • Request correction of inaccurate data.
  • Request deletion of your data.
  • Object to or restrict certain processing.
  • Data portability (receive your data in a structured format).

To exercise these rights, contact us at support@argraide.com.

10. Third-Party Services

We use the following third-party services:

  • Stripe: Payment processing for Marketplace transactions.
  • Supabase: Database and authentication infrastructure (hosted in AWS Canada).
  • Vercel: Hosting and content delivery.
  • PostHog: Product analyticsā€”configured with privacy-hardened settings that disable IP collection and mask all text (see Section 5.1).
  • AI Providers: Activity generation (content is processed but not stored by AI providers).

These services have their own privacy policies governing their use of data. Our configuration of these services prioritizes privacy and minimizes data exposure.

11. Changes to This Policy

We may update this Privacy Policy periodically. We will notify you of material changes via email or prominent notice on the Platform. The "Last Updated" date at the top reflects the most recent revision.
