Privacy Policy

Last updated: March 12, 2026

Overview

Roby ("the App") is a rent vs. buy financial calculator developed by Joshua Hart. This privacy policy explains how the App handles your information.

Data Collection

Roby does not collect any personal information. Specifically:

• No account or sign-up is required
• No personal, financial, or identifying information is collected
• No analytics, tracking, or advertising SDKs are included
• No cookies or similar tracking technologies are used
• No data is shared with third parties

On-Device Processing

All financial calculations are performed entirely on your device. The numbers you enter into Roby — home price, rent amount, income, and other financial inputs — never leave your device and are not transmitted to any server.

Network Requests

The App makes a single type of network request:

• State housing data: Roby fetches publicly available state-level housing statistics (median home prices, property tax rates, and insurance rates) from a GitHub-hosted data file. This request does not include any personal or device-identifying information. If the network is unavailable, the App falls back to a bundled copy of the data.

Device Permissions

Roby does not request access to your location, camera, contacts, photos, microphone, or any other device capabilities.

Children's Privacy

Roby does not collect personal information from anyone, including children under the age of 13.

Changes to This Policy

If this privacy policy is updated, the changes will be posted on this page with a revised "last updated" date. Material changes will be noted in the App's release notes.
