How your data flows
What DataGenStudio stores, where it lives, and who can see it.
Most of DataGenStudio runs in your browser. The server handles sign-in, AI requests and AI Chat; it never receives the rows you generate.
Where each kind of data lives
| Data | Where it lives | Who can see it | How long it’s kept |
|---|---|---|---|
| Your schema draft (tables, columns, sample values, domain context) | Your browser’s local storage | Only you, on that browser | Until you click Clear or clear your browser data |
| Generated rows | Your browser’s memory | Only you | Until you close or reload the tab |
| Downloaded zip | Your computer | Whoever you share it with | Up to you |
| AI prompts for drafts, imports, values and database lookups | Sent to the AI provider for each request | The AI provider processes it to answer | Not saved by DataGenStudio |
| Imported files and sketch photos | Sent to the AI provider to read the structure | The AI provider processes it to answer | Not saved by DataGenStudio |
| AI Chat conversations | Our database | You; anyone with the link if you make a chat Public | Until you delete the chat |
| Your account (email, password) | Our database; the password is stored only as a salted bcrypt hash | TeraGen AI | While your account exists |
| Usage counts (which AI action, and when) | Our database | TeraGen AI | Used for the daily limits |
What reaches the AI, step by step
| Step | Sent to the AI | Never sent |
|---|---|---|
| Draft with AI | Your description of the domain | — |
| Import a model | The file or photo you upload | — |
| Generate data | Table and column names, column hints, enum values, sample values, domain context | The generated rows |
| Other database lookup | The database name and version you typed | Your schema and rows |
| Explore and download | Nothing | Everything stays local |
AI requests go from our server to third-party model providers through Vercel AI Gateway. The AI service key stays on the server and is never exposed to your browser.
Treat anything you type or upload as something the AI will read. Use made-up sample values, and never upload files that contain real customer data.
Your controls
- Clear in step 1 removes your schema draft from this browser.
- Reloading the page discards generated rows.
- In AI Chat, delete a single chat, or use the trash icon in the sidebar to delete all chats.
- Chats are Private by default. Only switch a chat to Public if you mean to share it.
- To delete your account, email contact@teragenai.com from the address you signed up with.
