Notchit HUD Privacy Policy

Effective date: 2026-04-21
App: Notchit HUD
Bundle ID: com.unbundio.notchit

1. Data controller

Notchit HUD is developed and maintained by illuwa ("we", "us").

For any privacy-related inquiry, contact: master@divechain.app

2. Summary

Notchit HUD is a local system-monitoring utility. It does not collect, transmit, sell, share, or retain any personal data. There is no user account, no analytics SDK, no advertising SDK, no crash-reporting service, and no telemetry.

This policy exists for App Store transparency and to document the single optional outbound network request the app can make on the user's behalf.

3. What Notchit HUD does NOT collect

Notchit HUD does not collect, store, or transmit any of the following:

• Names, email addresses, phone numbers, or other contact details.
• User IDs, device IDs, advertising identifiers, or any tracking identifiers.
• Location data.
• Contacts, calendars, photos, messages, or files.
• Browsing or search history.
• Usage analytics, crash reports, or diagnostic logs (beyond what the operating system itself collects with the user's own Apple privacy settings).
• Performance metrics leaving the device. CPU, memory, network, disk, and battery readings are computed locally and rendered on-screen only.

No data is transmitted to us. We operate no server that receives data from the app.

4. The only outbound network call

Notchit HUD makes exactly one category of outbound network request, and only when the user explicitly opens the Network detail panel and its Addresses section:

• Endpoints:
  https://api.ipify.org (for public IPv4)
  https://api6.ipify.org (for public IPv6)
• Purpose: to display the user's own public IP address(es) to the user, as a convenience feature comparable to visiting whatismyip.com manually.
• Payload sent: none beyond the standard HTTPS request headers required by the OS networking stack (no custom headers, no body, no cookies, no identifiers).
• Response use: the returned IP string is rendered transiently in the Network detail panel and held only in memory for the duration of that view. It is not logged, written to disk, sent to any other service, or associated with any identifier by Notchit HUD.
• Opt-out: simply do not open the Network detail panel. No request is made otherwise.

This is the only outbound network traffic originating from the app's own logic. The operating system may independently make network requests (App Store receipt validation, macOS system services) that are outside Notchit HUD's control and outside the scope of this policy.

4a. Local network interface inspection (what "VPN" means in Notchit HUD)

The Network detail panel shows a small "VPN" badge next to the Public IP when a tunnel-style interface is currently active on your Mac. Notchit HUD is not a VPN app. It does not create, proxy, intercept, or route any network connection, and it does not link Apple's NetworkExtension framework or request any VPN-related entitlement.

The badge is computed entirely on the device from publicly enumerable kernel interface metadata, using the standard POSIX getifaddrs() call. If any interface whose name begins with utun, ipsec, ppp, tap, or tun is marked IFF_UP + IFF_RUNNING and has a non-link-local address, we render the "VPN" badge. The same information is visible in macOS System Settings → Network. No credentials, tunnel configurations, connection profiles, DNS records, or packet payloads are ever accessed. The resulting boolean is rendered to screen once per second while the panel is open and immediately discarded — it is never stored, logged, or transmitted.

5. Third-party services

The only third-party network endpoint Notchit HUD contacts is ipify (https://api.ipify.org, https://api6.ipify.org). ipify is a free public IP-lookup service. Like any web server, ipify may log the incoming request (which by design includes the requester's public IP, since that is what the service returns). Notchit HUD has no relationship with ipify and does not send ipify any additional information. Please consult ipify's own documentation and policy at https://www.ipify.org/ for their data-handling practices.

Notchit HUD includes no advertising, analytics, attribution, crash-reporting, or cloud-sync SDKs.

6. Children's privacy

Notchit HUD is a general-audience utility. It does not knowingly collect any data from anyone, including children under the age of 13 (or the equivalent minimum age in the user's jurisdiction), because it does not collect data at all.

7. Data retention

There is no server-side data to retain. Locally, Notchit HUD stores only:

• User preferences (selected display mode, segment visibility, refresh rate, palette choice, launch-at-login flag) in the standard macOS UserDefaults store, scoped to the app's sandbox.

These preferences never leave the device.

8. User rights

Because Notchit HUD collects no personal data, there is no personal data to access, correct, export, or delete under GDPR, CCPA, or similar regulations. If you wish to remove all Notchit HUD state from your device:

1. Quit Notchit.
2. Drag Notchit.app to the Trash.
3. (Optional) Remove preferences by running in Terminal:
   defaults delete com.unbundio.notchit

The currently reviewed build may still appear in Finder as Notchit.app even though the App Store product name is Notchit HUD.

9. Security

All Notchit HUD network requests use HTTPS (TLS). Notchit HUD runs under the macOS App Sandbox and holds only the entitlements strictly required for its monitoring features — exactly com.apple.security.app-sandbox and com.apple.security.network.client, nothing else.

10. Changes to this policy

We may update this policy to reflect new features or legal requirements. Material changes will be accompanied by a new Effective date at the top of this document and noted in the app's release notes.
