Privacy Policy
Effective Date: September 15, 2025
Quick Summary (Plain Language)
We know privacy policies can be long and legal. Here's the simple version:
- •Who we are: Checkmate is an app owned by Simovia, Inc.
- •What we collect: Parent account details, child's first name, grade level, homework uploads, role info (parent/guardian, teacher, tutor), and preferred language.
- •How we use it: To check homework using AI, build a private portfolio, and let invited people (like teachers or grandparents) view or upload work.
- •Who sees it: Only you and people you invite. We don't sell your data.
- •AI tools: We use trusted AI providers (like OpenAI) with “no data retention” settings.
- •Storage & security: Data is hosted on AWS + Supabase, encrypted in transit and at rest.
- •Deletion: If you delete your account, we delete all your child's data immediately.
- •Age: Parents must create accounts. Kids can't sign up directly.
- •Your rights: If you're in California or another state with privacy laws, you can ask us to see, delete, or correct your data anytime.
- •Contact us: Email privacy@checkmate.school for any privacy concerns.

Full Privacy Policy
1. Who We Are
This Privacy Policy explains how Simovia, Inc. (“Simovia,” “we,” “us,” or “our”) collects, uses, and protects your information when you use the Checkmate app (“Checkmate” or the “App”).
Our mailing address:
Simovia, Inc.7901 4th St N STE 300
St. Petersburg, FL, 33702
Email: privacy@checkmate.school
2. Information We Collect
When you use Checkmate, we may collect:
- Parent account information: Name, email, payment details (if paid features are used — processed via Stripe).
- Child information: First name, homework uploads, grade level.
- Invited user info: Role (parent/guardian, teacher, tutor), name, email.
- Preferences: Language choice.
- Analytics: We use Mixpanel to understand how Checkmate is used (no homework content is shared).
3. How We Use Information
We use this information to:
- Provide homework feedback through AI models.
- Create a private portfolio of your child's work.
- Allow invited users to view or upload homework.
- Improve our services (using anonymous, aggregated data).
- Process payments through Stripe (when applicable).
We do not sell your personal information.
4. AI Providers
- We use OpenAI (and may use Anthropic or Google in the future).
- All homework sent to these models uses zero data retention endpoints, so providers do not keep your child's data.
5. Hosting & Security
We host on AWS + Supabase.
Security measures include:
- TLS encryption (in transit)
- AES-256 encryption (at rest)
- JWT-based authentication with OAuth2/SSO
- Row-level security policies
- Audit logging
6. Data Sharing
We only share data with:
- Service providers (e.g., hosting, AI vendors, analytics, payments).
- Invited users you designate (who can view and upload work).
Invited users cannot invite others.
7. Data Retention & Deletion
- If you delete your account, all child data is deleted immediately.
- We may retain minimal billing records (if payments were made) as required by law.
8. Children's Privacy
- Parents create and control accounts.
- Children cannot create their own accounts directly.
- Because parents control access, Checkmate is not directed to children under 13 for independent sign-up.
9. State Privacy Rights
We honor privacy rights under California law (CCPA/CPRA) and other state laws. This means you may request:
- Access to your data.
- Correction of inaccurate data.
- Deletion of your data.
Requests can be sent to privacy@checkmate.school.
10. Changes to this Policy
We may update this policy from time to time. We'll notify you by email or in-app notice if changes are significant.
