Privacy Policy & Terms of Use
Last updated: Sep, 2026
1. Privacy Policy
Razi Calculator ("the Tool"), operated by Razi Digi, is designed to work entirely inside your browser.
- No account, no server-side calculations: numbers you enter (financial amounts, calculator inputs, conversion values, height/weight, date of birth, Zakat/Ushar figures) are processed locally on your device and are never transmitted to our servers.
- Local storage: your calculation history, memory value, Zakat/Ushar entries, currency preference, and light/dark theme preference are saved only in your browser's local storage so they persist between visits. You can clear them at any time from the relevant tab's "Clear Saved Data" option, the History & Memory tab, or by clearing your browser data.
- Cookies & analytics: if analytics or advertising services (such as Google Analytics or Google AdSense) are enabled on this site, they may use cookies or similar technologies to collect anonymized usage data (pages visited, approximate location, device type) in line with their own privacy policies.
- Third-party fonts: this site loads fonts (including "Roboto Mono", "Inter", and "Noto Nastaliq Urdu" for Urdu text) from Google Fonts, which may log standard request data (such as IP address) as part of serving the font files.
- Live currency rates: the Currency Exchange tab fetches exchange rate data directly from a third-party public API (open.er-api.com) from your browser; no personal data is sent with this request beyond standard network request information.
- No sale of personal data: we do not sell or share personally identifiable information with third parties.
2. Terms of Use
- The Tool is provided "as is" and free of charge for personal, educational, and informational use.
- Results from all calculators on this site — including the scientific calculator, Car Ijara calculator, Zakat and Ushar calculators, ECAT/MDCAT merit calculators, BMI calculator, unit converter, and currency converter — are estimates for informational purposes only and do not constitute financial, legal, medical, religious, or professional advice.
- The Age & Personality Insight, BMI Calculator, and AI Health Calculator tools are for entertainment and general informational purposes only, and are not a substitute for professional medical, psychological, or astrological consultation.
- The Zakat and Ushar calculators reflect commonly cited Hanafi fiqh positions as a general educational aid; they are not a fatwa. Please consult a qualified Islamic scholar or Dar-ul-Ifta for rulings specific to your situation.
- The Car Ijara calculator estimates payments using a standard amortization model for illustration only; actual Ijara contracts, profit rates, and ownership-transfer mechanics vary by financial institution.
- The ECAT and MDCAT merit calculators use commonly cited weightage as defaults, which you can adjust; always verify against your target institution's current official merit formula.
- Always verify important financial, religious, and admissions-related calculations with your bank, a qualified scholar, or the relevant institution before making decisions.
- Razi Digi is not liable for any loss or damage arising from reliance on results produced by this Tool.
- You may not use the Tool for unlawful purposes or attempt to disrupt, reverse-engineer for malicious use, or overload the service.
- These terms may be updated from time to time; continued use of the Tool after changes constitutes acceptance of the revised terms.
