Privacy Policy

Last updated: July 2025

At Mioo ("we", "us", "our"), accessible from https://mioo.site, your privacy is one of our highest priorities. This Privacy Policy document explains what minimal information we collect, how we use it, and the choices you have. By using our website, you agree to the practices described below.

1. Calculator Inputs Never Leave Your Device

This is the most important thing to understand about Mioo: all calculator computations run entirely in your browser using JavaScript. When you enter your Zakat amounts, inheritance details, or Hajj savings figures, that data does not get transmitted to our servers. We never see it, we never store it, and we have no way to recover it. You could complete a calculation while offline (after the page loads), and it will work.

We designed the platform this way because Islamic worship calculations involve sensitive personal financial information. The privacy of that information is a religious as well as a civil responsibility, and we take it seriously.

2. Information We Do Collect

We collect a minimal set of non-identifying information needed to operate the website:

  • Server logs: Standard web server logs include IP address, browser type, referring URL, pages visited, and timestamp. This data is used for security, debugging, and aggregate traffic analysis. IPs are not associated with any personal identity.
  • Cookies & local storage: We may use first-party cookies or browser local storage to remember preferences (e.g., selected currency, language). These are not used for cross-site tracking.
  • Contact form submissions: When you email us using the contact form, we receive your name, email, and message — solely to respond to your inquiry. We do not add you to any mailing list without explicit opt-in.
  • Newsletter (optional): If you subscribe to our newsletter, we store your email address and use a third-party email provider (e.g., Mailchimp) to send periodic updates. You can unsubscribe at any time using the link in every email.

3. Third-Party Services

Mioo uses the following third-party services that may collect limited data per their own policies:

  • Google AdSense: If ads are displayed, Google may use cookies to serve relevant ads. Users can opt out of personalized advertising via Google Ads Settings.
  • Google Analytics: Used for aggregate traffic analytics. IP anonymization is enabled. Users can opt out via the Google Analytics Opt-out Browser Add-on.
  • CDN services (Tailwind CDN, Google Fonts): These may log requests to deliver cached assets faster. Their privacy policies apply.

We do not sell, rent, or share your personal data with any other third parties.

4. Cookies

Mioo uses cookies for the following purposes:

  • Essential cookies: Required for the website to function (e.g., remembering language preference). These cannot be disabled.
  • Analytics cookies: Help us understand which pages are most useful so we can improve content.
  • Advertising cookies (if applicable): Used by Google AdSense to display relevant ads. You can opt out via your browser settings or Google's Ads Settings page.

You can control cookies through your browser settings. Most browsers allow you to refuse cookies or alert you when cookies are being sent. Please note that some parts of the website may not function properly without cookies.

5. Data Security

We implement reasonable technical and organizational measures to protect any information we do collect. However, no method of transmission over the internet or electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your data, we cannot guarantee absolute security.

Because calculator inputs never leave your device, there is no risk of those inputs being exposed in a server breach — there's nothing on our servers to expose.

6. Children's Privacy

Mioo is intended for a general audience and does not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can promptly delete it.

7. Your Rights

Depending on your jurisdiction (GDPR, CCPA, etc.), you may have the right to:

  • Request access to personal data we hold about you
  • Request correction or deletion of your personal data
  • Object to or restrict processing of your data
  • Withdraw consent to processing at any time
  • Lodge a complaint with your local data protection authority

To exercise any of these rights, contact us at contact@mioo.site.

8. Data Retention

Server logs are retained for a maximum of 90 days for security and troubleshooting purposes, then automatically deleted. Contact form submissions and email correspondence are retained for as long as needed to resolve your inquiry and for legitimate business records (typically up to 3 years).

9. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top of this page. We encourage you to review this page periodically. Material changes will be communicated through a prominent notice on the website.
