Calculator inputs and results are processed in the browser. Calculator OS does not receive or store entered rates, hours, amounts or calculated results.
Website analytics
PostHog Cloud EU measures page traffic and counts actions such as calculator starts and completions. The service is configured without cookies. Calculator inputs and results are not included, session recording is disabled and Contractor Calculator does not create visitor profiles.
After a completed calculation, an optional feedback form asks only for a broad professional role, whether the task was completed without help and whether the result confirmed or changed an assumption. Responses are counted by cookieless session. No rates, results, contact details or free text are collected.
Google Search Console provides aggregated information about how Contractor Calculator pages appear in search results. Its reports do not include calculator inputs or results.
