Privacy Policy

Last updated: July 7, 2026

This Privacy Policy explains how SigmaDojo ("we," "us," or "our"), a product of KodaBloom LLC, handles information when you use our website at sigmadojo.com (the "Service"). We keep the Service simple, and we collect as little as possible.

1. Information we collect

• Practice activity. When your child takes a test, answers and scores are stored locally in your browser (using your device's local storage). This information stays on your device and is not sent to us.
• Messages you send us. If you email us, we receive your email address and whatever you choose to include in your message.
• Basic server logs. Our hosting provider (Netlify) automatically records standard request data such as IP address, browser type, and pages requested, for security and reliability.
• Payments (when available). Paid purchases are not yet live. When they launch, payments will be processed by Stripe. We will not receive or store your full card details.

2. How we use information

We use information to operate and improve the Service, respond to your messages, keep the site secure, and (in the future) fulfill purchases. We do not sell your personal information, and we do not use it for third-party advertising.

3. Children's privacy

SigmaDojo is designed for parents and guardians to use with their children. Children do not create accounts or log in, and we do not knowingly collect personal information from children under 13. Practice activity is stored only on your device. If you believe a child has provided us personal information, contact us and we will delete it.

4. Cookies and local storage

We use your browser's local storage to save practice progress on your device. We do not use advertising or cross-site tracking cookies. Google Fonts is used to display our typeface, which may involve your browser contacting Google's servers.

5. Third-party services

• Netlify — website hosting.
• Google Fonts — font delivery.
• Stripe — payment processing (for future purchases).

6. Data retention

Practice data lives in your browser until you clear it. Emails you send us are kept only as long as needed to help you.

7. Your choices

You can clear practice data at any time by clearing your browser's site data. You can contact us to ask what information we hold about you or to request deletion.

8. Changes to this policy

We may update this policy from time to time. We will revise the "Last updated" date above when we do.
