Monarch Money – Balance Obfuscation (Tampermonkey)

Lightweight userscript that masks dollar amounts on Monarch Money to prevent shoulder‑surfing while you work. It adds a one‑click toggle in the sidebar and supports hover‑to‑reveal for individual values when masking is on. Fully compatible with Monarch Money Tweaks

What it does

• Masks currency: Replaces values like $4,201.28, -$150.00, and ($99.00) with a normalized pattern such as $*,***.**.
• Hover to reveal: When masking is on, hovering a masked value temporarily reveals the original amount.
• Sidebar toggle: Inserts an “Obfuscate Balances” control in Monarch’s left sidebar to turn masking on/off. Your choice is saved locally.
• Supported pages: /dashboard, /accounts, /transactions, /goals, /budget (plus legacy /plan), /investments.
• Performance‑aware: Scans only known containers; when masking is OFF it stays effectively idle.

Install (Tampermonkey)

1. Install Tampermonkey for your browser:
   • Tampermonkey for Chrome
   • Tampermonkey for Firefox
2. 🚀 Click here to install latest version - V1.3.2
3. Ensure the script is enabled while on an open Monarch Money tab.

The script only runs on https://app.monarch.com/*.

Usage

1. Visit Monarch Money.
2. In the left sidebar, click “Obfuscate Balances” to toggle masking.
3. With masking ON:
   • Amounts are replaced by a masked pattern.
   • Hover over any masked value to temporarily reveal it.
4. With masking OFF: the script idles and does not scan the page.

Notes and limitations

• The script primarily targets elements that contain a dollar sign. Amounts without $ may not be masked.
• Highly dynamic chart tooltips/SVGs are intentionally skipped to avoid UI jitter. Axis labels may be hidden while masking is ON.
• If Monarch updates its CSS class names, some areas may need selector updates.

Troubleshooting

• Toggle not visible: Wait a second after load; the script retries a few times as the sidebar mounts. If it still doesn’t appear, refresh the page.
• A value isn’t masked: If it has a $ and still isn’t masked, it may be in a newly introduced component. Open an issue with the page/section and a short HTML snippet or location for me to look at.

Uninstall / disable

• In Tampermonkey Dashboard, toggle the script off or delete it to remove all functionality.
