01
Calculator data
Provider names, tariffs, charging amounts, vehicle consumption, and calculation results stay in your browser or mobile device. ChargeWindow does not provide accounts, cloud sync, receipt history, location tracking, or live charger data.
02
Purchase and access data
Stripe processes payment details, billing information, receipts, tax information, and fraud signals under its own privacy terms. ChargeWindow receives a Checkout Session identifier and verifies payment status, Payment Link, Price, and quantity.
Paid access uses a signed, essential browser cookie. It contains an encoded Checkout Session identifier and expiry, not card or calculator data. The cookie lasts up to one year and is sent only to the paid app.
03
Hosting data
Hosting providers can process standard request data such as IP address, browser information, requested URL, timestamps, and error logs to serve and secure the service.
When a supported AI referrer or AI-related user-agent requests a content page, ChargeWindow writes a limited hosting-log event with source category, signal type, and requested path. ChargeWindow code does not add IP address, query text, full referrer, or full user-agent to this event. ChargeWindow does not run advertising trackers, browser analytics, or analytics cookies.
04
Your choices
You can remove local calculator data and the access cookie through your browser or device settings. Removing the access cookie locks the paid app on that browser; keep your Stripe receipt and original return link for recovery.
