This Privacy Policy explains how HisabTools (“we”, “us”), available at hisabtools.comand operated by DevNestTech, collects, uses and protects information when you use our website. By using the website you agree to this policy.
1. Information you enter into our tools
All calculators and tools on HisabTools run entirely in your web browser. The numbers, dates and text you type – such as loan amounts, dates of birth, passwords you generate or text you paste into the word counter – are processed on your own device and arenot sent to or stored on our servers.
Some tools keep small preferences or drafts in your browser’s local storage for your convenience (for example your light/dark theme choice, the word-counter draft and cached exchange rates). This data never leaves your device and you can clear it at any time through your browser settings.
If you use the “Share result” button, the values you entered are placed in the link so the recipient sees the same result. Only share links you are comfortable sharing.
2. Information collected automatically
Like most websites, our hosting provider (Cloudflare) processes technical information needed to deliver and protect the site, such as your IP address, browser type, device type and the pages requested. This is used for security, preventing abuse and keeping the service running.
We may use privacy-friendly analytics (such as Cloudflare Web Analytics) to understand which pages are popular. These analytics do not use cookies and do not track you across other websites.
3. Third-party services
- Exchange rates: the currency converter requests daily reference rates from ExchangeRate-API (open.er-api.com) and, as a fallback, Frankfurter (api.frankfurter.dev). These services receive a standard web request from your browser, including your IP address. No amounts you enter are sent.
- Fonts and scripts are served from our own domain; we do not load third-party font services.
4. Advertising and cookies (Google AdSense)
We use Google AdSense to show advertisements, which keeps HisabTools free. Please note:
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
- You may opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalised advertising atwww.aboutads.info.
- Learn more about how Google uses information from sites that use its services atpolicies.google.com/technologies/partner-sites.

7. Children’s privacy
HisabTools is a general-audience website. We do not knowingly collect personal information from children under 13. If you believe a child has sent us personal information, please contact us and we will delete it.
