Privacy Policy
SQLesse; (the website at sqlesse.com, the SQLesse browser extension, and the SQLesse CLI) · Last updated: September 8, 2026
The short version
SQLesse converts natural-language questions into SQL (or Python/R analysis code). To do that, it sends your typed question and, when available, table and column names to an AI model. It never reads, stores, or transmits the rows of your data, and it never connects to your databases.
What we process
- Your question — the plain-English request you type.
- Schema context — table/column names you paste, upload, or (in the extension) that are already visible in the tool you are using. Names only, never data values.
- SQL you paste into the Explain/Optimize/Validate tools.
These are sent to the AI backend to generate a response: by default SQLesse's own API (api.sqlesse.com, a Cloudflare Worker), which forwards them to Anthropic's Claude API for generation; or, if you configure your own key or backend, directly to that provider. Anthropic's handling is described in Anthropic's privacy policy.
What we do NOT do
- No account, sign-up, or login is required, and none exists.
- We do not connect to, query, or import your databases. Query execution on sqlesse.com happens inside your own browser against a local sandbox.
- We do not sell data, run ads, or use third-party analytics or tracking cookies.
- The extension does not read page content beyond detecting SQL editors and visible table/column names, and sends nothing anywhere except when you explicitly ask it to generate.
What stays on your device
- Settings, query history, learned phrase-to-column mappings, and any custom schema you add are stored locally (browser localStorage or extension storage).
- If you add your own Anthropic API key or a signing secret, it is stored on your device only and is never sent to sqlesse.com.
Service logs, rate limiting, and analytics
The public API keeps short-lived counters (by IP address) purely to enforce fair-use rate limits; they expire automatically within 48 hours. The website also records anonymous, aggregate usage counts (for example, "how many page views and questions today") with no cookies, no identifiers, no IP addresses, and no per-person profiles — there is nothing in them that could identify you. Cloudflare, our hosting provider, processes requests as described in Cloudflare's privacy policy.
Cookie policy
SQLesse sets no tracking or advertising cookies and uses no third-party analytics. The site keeps your settings and history in your browser's local storage (not cookies, never transmitted). Cloudflare may set strictly-necessary security cookies (such as bot-protection) required to serve the site; these are not used for tracking. Because no consent-requiring cookies exist, no cookie banner is shown.
Your choices
- Use your own Anthropic key or self-hosted backend so requests never touch SQLesse's servers.
- Clear the site's browser storage (or remove the extension) to delete everything stored locally.
