Privacy Policy

Nine Lives Audio

Effective March 22, 2026

$

The Short Version

Nine Lives connects to your Audiobookshelf server. Your books, your progress, your credentials — all of that stays between you and your server. We do not have a server. There is nothing to send data to even if we wanted to.

We do not collect analytics. We do not track listening habits. We do not run ads. If the app crashes and you choose to send a report, it goes to an email inbox and contains only technical diagnostics. That is the extent of it.

$

What Nine Lives Stores on Your Device

  • Audiobookshelf server URL, username, and password — encrypted with AES-256-GCM
  • Authentication token — encrypted at rest
  • A randomly generated device identifier (UUID) — not tied to hardware
  • Book metadata, playback progress, and bookmarks
  • Downloaded audiobook files
  • App preferences — playback speed, equalizer settings, theme, sync intervals
  • Locally computed listening analytics (the Nightwatch Dossier feature)

All of this lives on your device. None of it is transmitted to Static Hum Studio.

What Nine Lives Transmits

To Your Audiobookshelf Server

When connected, Nine Lives communicates directly with the server you configured. This includes authentication, library fetches, and progress synchronization. This traffic goes between the app and your server. Static Hum Studio is not involved in any part of that exchange.

Crash Reports (Optional)

If Nine Lives crashes, you may be asked whether you want to send a report. This is entirely opt-in — nothing is sent unless you actively choose to do so. Reports are delivered via your device's email client to Static@StaticHum.Studio.

A crash report includes:

  • Report ID, app version, and build information
  • Android version, device model, brand, and product
  • Stack trace of the crash
  • Available memory at the time of the crash
  • Your comment, if you chose to write one

Crash reports are retained only as long as needed to diagnose and resolve the reported issue, then deleted.

A crash report explicitly excludes:

  • Authentication tokens or server credentials
  • Server URLs or shared preferences
  • System logs (logcat)
  • Any audiobook content or library data
$

What Nine Lives Does Not Collect

  • No analytics or usage tracking of any kind
  • No device fingerprinting — no IMEI, no hardware identifiers
  • No third-party tracking SDKs or advertising frameworks
  • No location data
  • No collection or processing of audiobook content
  • No data transmitted to Static Hum Studio servers — there are no such servers
$

Children’s Privacy

Nine Lives Audio is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided personal information through the app, please contact us at Static@StaticHum.Studio and we will take steps to remove such information.

$

Your Control

  • Clear the app's data or uninstall it to remove everything stored locally
  • Manage downloaded audiobooks from the Downloads screen
  • Crash reporting is opt-in — you must actively choose to send each report
  • Server credentials can be changed or disconnected at any time from Settings
