Data handled by the application
The analyzer processes migration SQL and the context selections in JavaScript inside the current browser tab. The application has no database, account form, analytics SDK, advertising pixel, or application backend. It does not execute SQL or connect to PostgreSQL.
Storage and network requests
The application code does not save the entered migration text to local storage, cookies, or a remote service. Its Content Security Policy blocks application network connections. Reloading or closing the tab clears the entered text unless the browser itself restores form state.
Hosting and external links
The hosting provider may process ordinary request metadata, such as IP address and user agent, under its own privacy policy. Links to GitHub, Capafy, PostgreSQL documentation, and other external sites are governed by those services after you leave this site.
Scope and contact
Do not paste credentials, customer data, or secrets. Static heuristics are not proof of production safety. For privacy or support questions, email yasu20200121.web@gmail.com.
