Privacy Policy

What we collect

CalcVerse does not collect, transmit, store or sell the values you type into any calculator. Every calculation is executed by JavaScript running inside your own browser tab. There is no backend application, no database and no server-side processing of your inputs.

Local storage on your device

To make the site pleasant to return to, we store a small amount of data in your browser's localStorage. This never leaves your device and is not readable by us:

• Theme preference — whether you chose the light or dark interface.
• Saved calculators — the list of tools you starred.
• Recently used — the last few calculator pages you opened, so they appear on the home page.
• Last inputs — for some general-purpose calculators only. Health, finance and salary calculators are excluded from this by design, because those inputs are the most sensitive.

You can erase all of it at any time by clearing site data in your browser, or by using the "Clear" buttons on the home page for the saved and recent lists.

Cookies

We set no cookies. We run no advertising, no behavioural profiling and no cross-site tracking.

Server logs

The site is served as static files by a hosting provider. Like any web host, the provider may keep standard access logs containing IP addresses, timestamps, requested paths and user-agent strings for security and operational purposes. These logs record which pages were requested; they cannot contain calculator inputs, because those are never sent in a request.

Third parties

CalcVerse loads no third-party scripts, fonts, trackers or advertising networks. The pages request only files from this site's own domain. Nothing on the site calls an external API.

Children

The site is a general-audience reference tool and is not directed at children. Since we collect no personal information from anyone, we hold no personal information about children.

Your rights

Data-protection regimes such as the GDPR and CCPA grant rights of access, correction and erasure over personal data a service holds about you. Because CalcVerse holds no personal data, there is nothing for us to disclose, correct or delete. Data stored locally in your browser is under your direct control and can be removed by clearing your browser's site data.

Changes to this policy

If this policy changes, the "last updated" date at the top will change with it. Any change that affected data handling would be described here in plain terms.
