Planner inputs
The web app stores your selected load, bill settings, vehicle model, battery size, charging percentage, and saved profiles in browser or WebView storage on your device. These settings help the planner remember your preferences.
Privacy
Power Window keeps the release version simple.
The app estimates flexible electricity timing using market data and optional local settings. It does not currently require an account, location permission, contacts, photos, microphone, advertising ID, or payment information.
Market and demo connector data
Our backend stores Red Electrica market responses by date so the app does not call the source API on every visit. If you use the demo charger connector, the backend stores a random app user ID, demo device, charge plan, and command log. The demo connector does not control real hardware.
Hosting and infrastructure
Power Window is hosted on Cloudflare. Cloudflare may process technical information such as IP address, request metadata, and security logs to deliver, protect, and operate the service. We do not sell personal data.
Android and browser permissions
The Android wrapper uses internet access to load the Power Window website. Browser notifications are optional and are only used if you choose to set a local reminder. The app does not request precise location, contacts, camera, microphone, SMS, or phone permissions.
How long data is kept
Local planner settings stay on your device until you clear browser/app storage. Historical market data may be kept indefinitely because it is public market data. Demo connector records may be retained for testing and support unless deletion is requested.
