Local files. Local processing.
SQLite Lab runs SQLite inside your browser. The application does not upload database files, CSV contents, SQL queries, schemas, or results to a server.
What is stored on this device
When you choose “Save on this device,” database copies are kept in the browser’s Origin Private File System (OPFS). Successful queries from saved workspaces can be retained in local query history. The theme preference is also stored locally.
Temporary databases are kept in memory. Closing or reloading the page removes them. Query tabs are in-memory. Choosing Save editor query explicitly persists that query in the saved-query library, even from a temporary session. Practice drafts and completion also persist locally. Export a database before leaving if you want to keep it.
Control your local data
Use Saved workspaces to delete individual databases. Use Clear history in Query history to remove retained history. Delete named queries in Saved queries separately; deleting a database does not erase them. Clearing this site’s data through browser settings removes saved databases, history, and preferences.
Browser storage has limits
The browser controls storage quotas and may reclaim storage. Private browsing may restrict or disable persistence. The retention button asks the browser to keep storage, but it cannot guarantee that data will never be deleted. Exported files are the best way to keep an independent backup.
Website requests
Your browser requests this website’s HTML, scripts, fonts, and WebAssembly files from the hosting provider. The host can receive ordinary connection information such as your IP address and requested URL. This does not include the contents of files opened in the workspace. Private preview hosting may require you to sign in to access the website.
Advertising and analytics
This release includes no third-party advertising or analytics scripts. Future advertising belongs on the public content site, with the database workspace isolated on a separate origin. That integration will require an updated privacy notice before launch.
Files you export
Downloads are created locally. Result exports contain the current bounded preview, not necessarily the complete query result. BLOB cells are represented by a byte-count label, and CSV exports prefix spreadsheet-formula-like values to reduce accidental formula execution. Export data reruns a read-only query for complete CSV, JSON, Excel or PDF exports within their stated limits; it differs from preview downloads. Migration downloads include a report and require review. Database exports preserve the database contents.
Moving to a new domain
Browser storage is tied to the site’s origin. A new domain cannot see workspaces saved under the old one. Export your databases before a domain change, then reopen them on the new site.
