Technical details
Processing architecture
HappyFormatter loads the formatter implementation in the browser and runs the operation locally. The source you paste is not sent to a formatting API.
Browser security
The browser sandbox and same-origin policy limit what page code can access. The formatter cannot read arbitrary local files.
Analytics implementation
Anonymous page-level usage metrics may be collected. Those metrics do not include the code you paste into the editor.
