NetPad collects nothing, sends nothing, and stores nothing outside your own browser.
Every calculation — subnet and CIDR maths, timezone comparison, epoch conversion, Base64, JWT, URL and JSON decoding — runs inside the extension on your own machine. NetPad makes no network requests of any kind. There is no server, no account, no analytics, no telemetry, no error reporting and no advertising. Whatever you paste into it, including internal addresses, hostnames and tokens, never leaves your computer.
NetPad saves two things using chrome.storage.local, the
browser's own extension storage on your device:
That is all. chrome.storage.local is local to your browser
profile and is not synchronised to any Google account or to us. Removing the
extension deletes it.
Text you type or paste into the panel is held in memory only while the panel is open, and is discarded when you close it.
Selecting text and choosing Open in NetPad passes your selection to the extension so it can be decoded. Chrome hands the selected text directly to the extension as part of the click event.
NetPad requests no access to the pages you visit. It has no host
permissions, no activeTab permission and no content scripts, so
it cannot read any page, see your browsing history, or act on any site. It
only ever receives text you have deliberately selected and sent to it.

There are none. No third-party services, no libraries loaded from a CDN, no fonts fetched from Google Fonts. The IBM Plex typefaces are bundled inside the extension package and load from disk.
NetPad is a technical utility with no accounts and no data collection, and is suitable for all ages.
If this policy ever changes, the updated version will be published here and the date above will change. Any future feature that needed a network connection would be optional, requested at the moment you chose to use it, and disclosed here first.
