Privacy Policy

Last updated: April 6, 2026

SheetBrain ("we", "our", "us") is committed to protecting your privacy. This Privacy Policy explains what data we collect, how we use it, and your rights regarding your information.

1. Information We Collect

Account Information: When you use SheetBrain, we collect your Google account email address to identify your account, track usage, and manage your subscription.

Spreadsheet Context: To generate accurate formulas, SheetBrain reads limited metadata from your active spreadsheet:

• Column headers and their positions
• Data types (text, number, date, currency)
• An optional small sample of data rows (up to 5 rows) if you enable sample sharing for better accuracy
• Sheet names and named ranges

This context is sent to our AI service to generate relevant formulas. We do not store your spreadsheet data. It is processed in-memory and discarded immediately after generating the response.

Usage Data: We track the number of AI calls you make per month for billing purposes. We log the type of request (generate, explain, or debug) but do not permanently store the content of your queries.

Payment Information: If you subscribe to SheetBrain Pro, payment is processed by Razorpay. We do not store your credit card details. We receive your Razorpay customer or subscription identifiers and subscription status from Razorpay.

2. How We Use Your Information

• Provide the Service: Generate, explain, and debug formulas based on your natural language queries and sheet context.
• Usage Tracking: Count your monthly AI calls to enforce free tier limits and manage Pro subscriptions.
• Billing: Process payments and manage subscriptions through Razorpay.
• Improve the Service: Analyze aggregate usage patterns (not individual data) to improve formula accuracy.

3. Sharing & Disclosure of Google User Data

SheetBrain accesses the following Google user data through the permissions you grant:

• Google account email address (via the userinfo.email scope)
• Spreadsheet metadata from your active sheet (via the spreadsheets.currentonly scope) — including column headers, data types, sheet names, named ranges, and optionally a small sample of data rows

We share, transfer, or disclose this Google user data only with the following third-party service providers, solely for the purposes described:

• Anthropic (Claude AI): Receives your formula-related prompts and spreadsheet context (such as headers, data types, sheet names, named ranges, and optional sample rows) to generate, explain, and debug formulas on your behalf. Subject to Anthropic's Privacy Policy.
• Supabase: Stores your Google email address for account identification, usage tracking, and subscription management in a secure PostgreSQL database. Subject to Supabase's Privacy Policy.
• Razorpay: Receives your Google email address and billing metadata to create and manage your payment and subscription records. Subject to Razorpay's Privacy Policy.

We do not sell, rent, or trade your Google user data to any third party.

We do not share Google user data with any parties beyond those listed above, except where required by law.

We do not use Google user data for advertising, retargeting, or any purpose unrelated to providing and improving SheetBrain's core functionality.

Google user data accessed through Google Workspace APIs is not used to develop, improve, or train generalized artificial intelligence or machine learning models.

4. Third-Party Services

SheetBrain uses the following third-party services:

• Anthropic (Claude AI): Processes your natural language queries and sheet context to generate formulas. Subject to Anthropic's Privacy Policy.
• Razorpay: Handles payment processing for Pro subscriptions. Subject to Razorpay's Privacy Policy.
• Supabase: Stores your account information (email, plan, usage count) in a secure PostgreSQL database. Subject to Supabase's Privacy Policy.

5. Data Retention

• Spreadsheet context: Not stored. Processed in-memory and discarded immediately.
• Account information: Retained as needed to operate your account, manage billing, and meet legal obligations.
• Usage and operational logs: Retained only as needed for billing, security, debugging, and service operations.

6. Data Security

We take security seriously. All data is transmitted over HTTPS. Our backend uses API key authentication, rate limiting, and input validation. Spreadsheet data is never written to disk or logs.

7. Your Rights

You have the right to:

• Access: Request a copy of the data we hold about you.
• Deletion: Request deletion of your account and all associated data.
• Correction: Request correction of inaccurate information.

8. Children's Privacy

SheetBrain is not intended for use by children under 13. We do not knowingly collect information from children under 13.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify users of significant changes through the add-on or via email. Continued use of SheetBrain after changes constitutes acceptance of the updated policy.
