Privacy Policy

Last updated: July 1, 2025

ExcelForm ("we", "us", "our") is committed to protecting your privacy. This policy explains what data we collect and how we use it.

1. What we collect

• Formula queries: Your formula descriptions and inputs are sent directly to Anthropic's Claude API to generate responses. We do not store these on our servers.
• Local storage: We store your language preference and daily query count in your browser's localStorage. This data never leaves your device.
• Analytics: We may use privacy-respecting analytics (no cookies, no cross-site tracking) to understand aggregate usage patterns.

2. What we do NOT collect

• We do not require account creation or email registration.
• We do not store your spreadsheet data, formulas, or queries on our servers.
• We do not sell or share your data with third parties for advertising.
• We do not use tracking cookies.

3. Third-party services

Your formula queries are processed by Anthropic via their API. Please review Anthropic's privacy policy for details on how they handle API requests.

4. Data retention

Since we don't store your queries, there is no personal data to delete from our servers. You can clear your browser's localStorage at any time to remove your locally stored preferences.

5. Children's privacy

ExcelForm is not directed at children under 13. We do not knowingly collect data from children.
