Privacy

Calculator inputs, scenario names, results and exports stay in your browser. They are not sent to our server. Saving is optional and stores calculations on this browser/device; use Delete saved data to remove them. Your language and optional measurement choice may also be saved locally.

Review submissions send only the review text, display name, language, publication consent and a retry identifier. Do not include private business information. Pending reviews are visible only to the owner; approved reviews become public.

Optional measurement sends fixed tool names and event types only. It does not send numbers, scenario labels, session identifiers or saved calculations. Withdraw consent using the same checkbox. Aggregate event counts are not unique visitor counts.

The hosting provider necessarily handles technical connection data such as IP addresses. The application does not store IP addresses with reviews or events. Application rate limits use aggregate daily counters. Reviews are retained for moderation until removed by the owner.

Advertising and affiliate tracking are disabled in this initial release. No third-party scripts or fonts load. Introducing advertising requires a privacy and storage-isolation review first.
