JOWB is an independent software studio. We design and ship lightweight utilities that help developers test, debug, and explore on their own devices — without spinning up a separate Mac or remote server.
A pocket-sized developer console for iOS and macOS. Paste HTML, run it on a real local origin, test WebRTC, fetch, camera and microphone APIs directly on your device.
Last updated: April 27, 2026.
JOWB and its apps do not collect, store, or transmit personal user data. There are no analytics, no tracking SDKs, no advertising identifiers, no accounts, and no third-party services beyond the Apple-provided frameworks described below.
Some apps include features that require device-level permissions
— camera, microphone, location, speech recognition, and local
network access. These permissions are used only by functionality the
user explicitly invokes (for example, loading a web page that calls
getUserMedia() or navigator.geolocation).
The app itself does not capture, read, or transmit camera frames,
microphone audio, or location data. Such data is delivered directly
to the user’s own in-app content (e.g. a web page running in
the embedded WebView) and does not leave the device unless the user
themselves sends it, for example by typing a network request command.
Location access, when granted, is forwarded to the embedded WebView
for standard navigator.geolocation calls made by
user-loaded pages. JOWB does not read, store, log, or transmit
location data, and the app performs no background location
monitoring.
Speech recognition, when used, is processed via Apple’s Speech framework. Audio is handled by Apple under Apple’s privacy terms; JOWB does not receive, store, or log audio recordings or transcripts.
User-created content (HTML/JS pasted into the app, saved scripts, key-value entries) is stored locally inside the app’s sandbox. It is included in standard iCloud device backups if the user has those enabled, exactly like any other app data. JOWB has no access to it.
Our apps are not directed at children under 13 and do not knowingly collect data from anyone, including children.
If this policy changes materially, we will update the date above and post a notice on this page.
