The calculators work in your browser. Without configured services, scenarios, feedback text and email addresses are not automatically sent to external services.
Shared plans
A shared link stores technical conditions in its URL fragment. Anyone receiving the link can read those conditions. Do not include names, addresses or personal notes.
Optional services
Analytics, feedback and newsletter services are disabled by default. Before enabling them, document the provider, data scope, retention and any required regional consent. The server or hosting provider may separately keep technical access logs.
Tools run locally in your browser. No external analytics, feedback or newsletter service is currently connected. The correction tool prepares a local copy or download; it does not transmit a report.
