The website

OhmCalc runs calculator logic in YOUR browser.

It does NOT send your calculator inputs to a remote compute service.

Your component values and intermediate results stay in the page on your device.

I strongly urge you to double check this yourself, and NOT TAKE MY WORD FOR IT.

I still log a small amount of usage data on the server so I can see whether the site is up, whether people are using it, and whether traffic looks human or automated.

I log that data so I can tell:

• Whether the calculator app works and whether anyone is using it at all.
• If the project is worth continuing to host and refine.
• If the traffic is from real people or bots.
• If there is something I can do to improve the project.

Analytics collected

• Page views, page requests, page URL, page title, and referrer
• Browser language, screen size, browser family, operating system, and device type
• A temporary session ID used only to count active browser sessions during a visit
• Aggregate request and page-view counts used for internal diagnostics

Not collected

• Your circuit calculations or form inputs on the page
• Any uploaded files, because this app does not use them
• Accounts tied to your real identity by default
• Accounts or persistent cross-visit profiles

Note: If you deploy behind a CDN or reverse proxy, that layer may maintain its own access logs outside this app.

Retention

• Raw analytics events are kept for a short server-side retention window
• Longer-term reporting is stored only as totals and daily summaries
• The session ID resets with the browser session instead of persisting across visits

This page should be updated again if you later add per-calculator telemetry or any external analytics service.

Feedback

Feedback and change requests should go through the maintainer or the repository where this app is hosted.
