Privacy Policy

Account and sign-in providers supply identifiers such as your email address and basic profile details. Stripe handles checkout, payment methods, invoices, and subscription status. The site stores only the entitlement and event metadata needed to decide which tools and files your signed-in account may access.

The contact form collects your name, reply email, optional company, topic, and message. Cloudflare Turnstile checks for automated abuse, and Cloudflare Email Service delivers the message to the support Gmail inbox. Message bodies are not stored in the site databases, R2 file storage, Git, or browser storage. The support mailbox retains messages as needed to answer and document the request.

Cloudflare processes aggregate request and visit metadata at the proxy edge so the site can improve navigation, reliability, and useful content. The site does not add an analytics cookie, local-storage tracker, advertising pixel, or session-replay script. Account, payment, contact-form, and private-download values are not sent as public analytics event fields.

Values entered into calculators, simulators, planners, and field-record builders are processed in your browser and are not sent to application servers, databases, analytics, or third-party storage. Some tools use browser localStorage for optional draft restoration. Those drafts can be lost when browser data is cleared, private browsing is used, or another device is used; export important work and use the visible reset action to remove a local draft.

Cloudflare provides hosting, security, storage, and email delivery; Google provides sign-in when chosen; Stripe provides billing. Each provider processes information under its own terms and privacy policy. Operational records are kept only as long as needed for access, security, support, accounting, dispute, and legal obligations, then removed or de-identified when practical.

You may ask about, correct, or request deletion of support and account information, subject to billing, fraud-prevention, and legal retention needs. Reasonable technical and administrative safeguards are used, but no online service can guarantee absolute security. This site is intended for working professionals and is not directed to children under 13.
