Privacy Policy
Last updated: September 27, 2026
1. Introduction
Calculator Sathi provides free online calculators. This page describes the data handling built into the current website. Hosting providers and any services added later may have separate practices; review those providers' notices when applicable.
2. Information We Collect
No account is required. Calculator inputs are calculated in your browser by the current site code. The site does not include an account system or a server-side calculator submission endpoint.
- Browser storage: The site may save your theme, favourites, recent calculator list, or a Kid Zone quiz best score in local storage on your device. It is not transmitted by the site code.
- Hosting logs: The hosting provider may process technical request data, such as IP address and requested page, to deliver and secure the site. Check your provider's privacy information.
- Contact: The current contact page has no form or configured public email address, so it does not collect a contact submission.
3. How We Use Information
- To operate, maintain and improve the calculators and website.
- To remember selected preferences and calculator shortcuts in your browser.
- To deliver the requested web pages and help the hosting provider protect the site.
4. Cookies and Similar Technologies
The current site code uses browser local storage for selected preferences, calculator lists, and the Quick Math Quiz best score. It does not intentionally set cookies. Hosting infrastructure or future third-party services may behave differently. See our Cookie Policy.
5. Third-Party Services
The current site does not configure analytics, advertising, or affiliate tracking. The page uses Google Fonts through an external stylesheet, which can make a request to Google when loaded. Hosting and third-party services may process request data under their own policies. This site does not sell personal information.
6. Data Security
We take reasonable technical and organizational measures to protect information from loss, misuse or unauthorized access. However, no method of transmission or storage over the internet is completely secure, and we cannot guarantee absolute security.
7. Children's Privacy
The calculators are general-purpose tools and do not ask for a user's age or account details. Do not enter sensitive personal information into calculator fields.
8. Your Choices
You can clear this site's local storage and cookies through your browser settings. Clearing local storage removes saved preferences and calculator lists.
9. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with a revised "Last updated" date. Continued use of Calculator Sathi after changes are posted means you accept the updated policy.
