Privacy Overview

Local-first data handling

The app only requests what it needs for solar and price estimation, and most persistence stays in the browser.

Location data usage

Your location is used only to provide solar energy estimates for your area. This information is sent to the solar estimation API so the forecast can reflect local conditions.

Local storage

Your settings and cached API responses are stored locally in the browser to improve performance and reduce unnecessary API calls.

Data sharing

We do not sell or distribute your personal data. External communication is limited to the solar and market APIs required to generate recommendations.

Retention

Cached data remains on your device and can be cleared manually. No personal data is retained on Wattlyzer servers.
