How We Handle Your Data

What we store

SheetEngine stores the minimum data needed to provide the service:

  • Account information - your email, display name, and Google account link
  • Project metadata - project names, creation dates, and linked spreadsheet IDs
  • Conversation history - your chat messages with the AI (used for context within each project)
  • Draft code - unsaved code changes in the editor
  • Deploy snapshots - records of past deployments
  • Transaction history - credit purchases and usage records

What we don't store

  • Your spreadsheet data - SheetEngine never reads or stores cell values, formulas, or any data from your sheets. It only works with the Apps Script code.
  • Payment details - credit card information is handled entirely by Stripe and never reaches our servers
  • Google passwords - authentication is handled via Google OAuth

Security

  • All data in transit is encrypted via HTTPS
  • OAuth tokens are encrypted before storage
  • All connections to third-party services (Google, Stripe, AI providers) use encrypted channels

AI interactions

When you send a message to the AI agent:

  • Your message and conversation context are sent to the AI provider for processing
  • SheetEngine does not use your data to train AI models
  • Each conversation is scoped to a single project

Data deletion

You can delete your account and all associated data at any time from the Settings page. See Account Deletion for details.
