Privacy Policy

Math Sprint is privacy-first. We do not collect usage telemetry or send any usage data to external analytics services. We also do not create server-side accounts or collect email addresses except when you explicitly provide one in the optional feedback form.

What We Store

The following data is stored locally in your browser's localStorage only and is never transmitted to our servers by default:

• Player Name: The display name you provide during onboarding (required). It is stored locally in your browser's localStorage for personalization and is not transmitted to our servers by default.
• Game Progress: High scores, sparks, inventory, achievements, and daily-challenge records.
• Settings: Volume, accessibility preferences, and game customization options.

Feedback and Optional Email

If you choose to submit feedback, the feedback form allows you to include an optional name and email address so we can follow up. Feedback submissions are sent to a third-party form provider (Formspree). Any email address you include in a feedback submission is used only to respond to your message and is not used for marketing or shared with third parties.

If you want your feedback or the email you provided removed from that provider's records, contact us via the feedback form and we will request deletion from the provider on your behalf.

Your Rights & Deleting Data

Your game data and player name are stored locally in your browser. To remove these, clear your browser site data or localStorage for this site. If you submitted feedback and included an email, contact us via the feedback form to request removal of that submission from the third-party provider.

Data Security

We take care to avoid sending personal data outside the browser unless you explicitly submit it (for example, via the feedback form). Feedback submissions are transmitted securely using HTTPS and processed by Formspree under their privacy practices.

Contact & Updates

For privacy questions or to request deletion of feedback submissions, please contact us through the in-game feedback form. We may update this policy over time; the latest version will always be available on this page.

Policy Updates

We may update this privacy policy from time to time. The latest version is always available on this page. Continued use of Math Sprint constitutes acceptance of the current privacy policy.
