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.
