Privacy Policy
Effective date: 8 July 2026
Your files never leave your device
SmartQueryTools is built so that we cannot see your data. Every file you open — CSV, Parquet, JSON, Excel, or any other supported format — is processed entirely inside your browser using WebAssembly (DuckDB-WASM). There is no upload step. File contents are never transmitted to our servers or to anyone else. When you close the tab, the data is gone.
No accounts
You do not need an account to use SmartQueryTools, and we do not offer one. We do not collect names, email addresses, or any other personal details in order to use the tools.
Dataset search in the Data Catalog
The Data Catalog lets you search public data portals such as Our World in Data, CKAN-based portals, and Socrata. When you type a search, the search text — and only the search text — is proxied through our API to the relevant portal so we can return results. Your files are never involved in these requests, and we do not store your search queries.
Remote datasets in the SQL workspace
If you load a remote dataset in the SQL workspace, your browser fetches that dataset directly from the third-party host that publishes it. The request goes from your device to that host — it does not pass through our servers. The host may see your IP address and standard request details, as with any website you visit, and its own privacy policy applies to that request.
Hosting logs
The site is hosted on Vercel. Like most hosting providers, Vercel may log standard request metadata — such as IP address, user agent, and requested URL — for operational and security purposes. These logs relate to page and API requests only; they never contain your file data.
No advertising, no cookies set by us
We do not run advertising on this site and we do not set cookies. There are no ad networks or third-party marketing scripts on our pages.
Changes to this policy
If we change this policy, we will update this page and revise the effective date above. Material changes — for example, if we ever introduced analytics — would be reflected here before they take effect.
