Privacy Policy

1. Introduction

Welcome to FinCalc Tools (accessible at https://tool.aktechstudio.com). We are committed to protecting your personal information and your right to privacy. If you have any questions or concerns about this privacy policy, please contact us.

2. Local-First Processing

The majority of our calculators (such as the Loan, Tax, Salary, and ROI calculators) execute computations 100% locally inside your web browser. The numeric parameters, wages, rates, and invoice items you input are processed in memory and are never uploaded, stored, or transmitted to any external server.

3. Information We Collect

When using our premium features, we may collect the following data:

• Firebase Account Data: If you sign in using Google Auth, we store your Firebase UID, display name, profile image URL, and email address to authenticate your session and manage your saved assets.
• Redirection Click Logs: If you create or visit a shortened URL through our serverless redirection system, our Cloudflare Pages Functions server logs transaction-based metadata. This includes visitor country, city, referring domain, user-agent device profiles, and access timestamp to populate your analytics charts. IP addresses are processed in memory to resolve geolocations but are not stored in D1.

4. Third-Party Services & Cookies

We use reputable third-party services to host and monetize our applications:

• Google AdSense: Google uses cookies to serve ads based on your prior visits to this website. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to our site and/or other sites on the Internet. Users may opt out of personalized advertising by visiting Ad Settings.
• Firebase Authentication & Firestore: Used to securely identify accounts and save user configurations.

5. GDPR & CCPA Rights

Under the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA), you have the right to request access to your data, request corrections, or request deletion of your account and links. Since we do not record visitor IP addresses in D1 click logs and store all user assets under authenticated Firebase accounts, you can delete all your shortened links and account information instantly via the user profile dashboard.
