JOWB
Developer tools for iOS & macOS.

We make small, focused developer tools.

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.

Apps

JS Shell

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.

Privacy Policy

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.

Permissions

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

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

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.

Local data

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.

Children

Our apps are not directed at children under 13 and do not knowingly collect data from anyone, including children.

Changes

If this policy changes materially, we will update the date above and post a notice on this page.
