Privacy

Effective October 13, 2026

Rental Bill Tracker is a program you install on your own Windows computer. It is designed so that your bills, receipts, properties and tenants stay on that computer. This page explains what information is involved, where it goes, and who can see it.

Information in the app stays on your computer

Everything you enter or add — your LLCs, properties, units, tenants, bills, receipts and the documents themselves — is stored on your computer: documents in a “Rental Bills” folder in your Documents, and the app’s records in your Windows user folder. The app has no online account, does not upload your information, and does not send us usage statistics, crash reports or any other data about what you do in it.

The app reads text from your documents on your computer, using the PDF’s own text or the text recognition built into Windows. That reading happens locally.

Backups

The app makes backups to a folder you choose. If that folder is synced by a service such as OneDrive or Dropbox, your backups are handled by that service under its own privacy terms. We never receive them.

Optional: reading with Claude

If — and only if — you turn on “Smarter reading with Claude” in Settings and enter your own Anthropic API key, the text the app has read from each new document is sent to Anthropic’s Claude service to help fill in the form. The document file itself is not sent. That exchange is between you and Anthropic under your account and Anthropic’s terms; it does not pass through us. This feature is off by default.

Licensing

Activation works without the internet. When you ask for a license key, you send us your computer code yourself, by email. The code is derived from an identifier Windows assigns to your computer’s installation and contains no personal information or files. To provide and support your license we keep your name, the contact details you gave us, your computer code and the key we issued. We use them only to support your license and contact you about it, and we don’t sell or share them.
