Xenon54 Universal Tracker

A private, local-first app that keeps every part of your day in one place.

Xenon54 Universal Tracker is a mobile app that lets you track your trading killzones, spending, quick notes, groceries, workouts and body metrics — each in its own focused tab. Everything works offline and stays on your device, with optional private backup and multi-device sync to the hidden app folder of your own Google Drive.

What you can track How backup works

One app, six focused trackers

Each section is a purpose-built tab. Use only what you need — nothing is ever sent to a server we control.

🎯

Killzones

Plan focus windows and get OS reminders when each one starts.

💸

Spend

Log subscriptions and expenses to see where your money goes.

🧠

Capture

Quick brain-dump notes, including optional voice notes transcribed on-device.

🛒

Household

Grocery and recurring household items that re-add themselves.

🏋️

Body

Track workouts, body metrics and nutrition logs over time.

📈

Trading

Keep a private journal of trades and review your performance.

Private by design

There is no backend server. We do not collect accounts, analytics, telemetry, or location data. Everything you enter is stored locally on your device.

No sign-up required to use the app.
No ads, no trackers, no third-party analytics.
Voice recordings stay on-device and are excluded from sync.
Reset or uninstall wipes your local data at any time.

Optional Google Drive backup

When (and only when) you sign in with Google from the Profile screen, Xenon54 Universal Tracker can back up and sync your data to your own Google Drive.

🔒

Your account only

Backups are written to your Drive's hidden appDataFolder — a private area only this app can see. We have no access to them.

🗝️

Minimal access

Xenon54 Universal Tracker requests a single scope, drive.appdata. It cannot see, modify, or share any of your other Drive files.
