Privacy Policy

At Ahasn.xyz ("we", "us", or "our"), accessible from https://ahasn.xyz, your privacy is fundamental to how we operate. This Privacy Policy explains what limited information we collect, why we collect it, how we use it, and the rights you have over your data. By using our website, you agree to the practices described in this policy.

1. Information we collect

We collect minimal information necessary to operate and improve the website. The categories of data we may collect include:

• Anonymous analytics data: We collect aggregated, non-personal information such as page views, browser type, device type, country (at region level), and referring URLs. This data is used to understand which calculators are most used, which browsers we need to test, and where our audience is located. We do not link this data to individuals.
• Information you provide voluntarily: If you contact us through our contact form or email, we receive the name, email address, and message content you provide. We use this solely to respond to your inquiry and do not add you to any marketing list.
• Calculator inputs: All values you enter into our calculators (grades, numbers, dates, etc.) are processed entirely in your browser using JavaScript. They are never transmitted to our servers, stored in our databases, or associated with you in any way.

2. How we use your information

We use the limited information we collect for the following purposes:

• To operate, maintain, and improve the website and our calculators
• To understand aggregate usage patterns and prioritize new features
• To respond to your inquiries and provide support
• To monitor for fraud, abuse, and security threats
• To comply with legal obligations

We do not use your information to build personal profiles, sell to third parties, or for any purpose beyond what is described in this policy.

3. Cookies and similar technologies

Ahasn.xyz uses a minimal set of cookies and similar technologies:

• Essential cookies: Required for the website to function correctly (e.g., remembering your menu state on mobile).
• Analytics cookies: Used by our analytics provider to compile anonymous usage statistics.
• Advertising cookies: Used by our advertising partners to display relevant ads. We do not share personal data with advertisers because we do not collect personal data.

You can control or disable cookies through your browser settings. Disabling cookies may affect some website functionality but will not prevent you from using any calculator.

4. Third-party services

We use a small number of trusted third-party services to operate the website:

• Google AdSense: Displays contextual advertisements. Google may use cookies to serve ads based on your prior visits to our site or other sites. You can opt out of personalized advertising via Google Ads Settings.
• Analytics provider: We use an analytics service to understand aggregate usage. This data is anonymized and not linked to individuals.
• CDN providers: We use Cloudflare and similar services to deliver fonts, stylesheets, and scripts quickly and securely.

These third parties have their own privacy policies governing how they handle data. We encourage you to review them.

5. Advertising and AdSense

Ahasn.xyz displays advertisements through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the internet. You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of third-party vendors' use of cookies for personalized advertising by visiting aboutads.info.

6. Data security

We take reasonable technical and organizational measures to protect the limited data we hold. These measures include encrypted connections (HTTPS/TLS) for all traffic, secure hosting infrastructure, regular security updates, and access controls limiting data access to authorized personnel only. However, no method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.

7. Your rights

Depending on your location, you may have the following rights regarding your personal data:

• Right of access: Request a copy of any personal data we hold about you.
• Right to rectification: Request correction of inaccurate personal data.
• Right to erasure: Request deletion of your personal data.
• Right to object: Object to processing of your data for specific purposes.
• Right to withdraw consent: Withdraw consent for any processing based on consent.

To exercise any of these rights, contact us at contact@ahasn.xyz. We respond to all valid requests within 30 days.

8. Children's privacy

Ahasn.xyz is designed for students of all ages and does not knowingly collect personal information from children under 13 (or the minimum age in your jurisdiction). Because we do not collect personal information from any user — including through accounts or sign-ups — children can safely use all calculators. If you believe a child has provided us with personal information, please contact us and we will promptly delete it.

9. International users

Ahasn.xyz is accessible worldwide. If you access the site from outside the country where our servers are located, please be aware that your information will be transferred to and processed in that country. By using the website, you consent to this transfer. We comply with applicable data protection laws including the GDPR (European Union), CCPA (California), and other regional regulations.

10. 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 policy periodically to stay informed about how we protect your information. Material changes will be communicated through a prominent notice on the website.
