Production answer · privacy and storage
Where does a label project live?
The working project is stored in IndexedDB in the current browser profile when available. If storage fails, the app reports memory-only mode and the project will not survive leaving the page.
Why this matters
No application account, server database, tracking SDK, remote font, or runtime analytics dependency is required.
A reviewable sequence
- Avoid unnecessary personal or sensitive information.
- Export checkpoints regularly.
- Use an appropriate organization-controlled transfer and backup process.
- Clear browser data only after confirming independent copies.
