Privacy policy

Calculator inputs

Inputs entered into calculators are processed locally in the browser and are not stored on our servers.

Browser storage

We use browser-local storage for essential preferences such as consent settings. Recent-calculator and personalization signals are only kept after analytics consent is granted.

If you contact us

If you email us, we receive the information you choose to send, which may include your email address, the message itself, and any screenshots or example values you provide. We use that information only to review the issue, reply, and keep a basic support record when needed.

Analytics

If you allow analytics, this site may load Google Analytics, Vercel Analytics, and Vercel Speed Insights to measure traffic, diagnose performance, and improve navigation and calculator quality.

Advertising and third parties

If you allow advertising, this site may load Google AdSense. AdSense can use cookies or similar local storage for ad delivery, measurement, fraud prevention, and frequency controls where permitted by law and your consent choices. Infrastructure and analytics providers may also process limited technical data such as IP address, browser type, referrer, and page-performance signals to keep the site available and measurable.

Retention and deletion

Consent preferences remain in your browser until you clear storage or change them. Support emails may be retained for as long as reasonably necessary to handle the request, resolve abuse, or keep basic business records.

Sensitive information

Avoid sending bank details, tax IDs, medical records, passwords, or other sensitive personal data through calculator inputs or support emails. Use sample values whenever possible when reporting a bug.

Your choices

You can update analytics and ad consent at any time.
