Welcome to Kalqo ("we," "our," or "us"). We are committed to protecting your privacy and ensuring transparency about how we collect, use, and safeguard your information. This Privacy Policy explains our practices regarding data collection when you use our website and calculator services (the "Service").

When you create an account or sign in through our authentication provider, we collect your name, email address, and a unique identifier. This information is used to personalize your experience, save your calculation history, and manage your account.

2.2 Calculation Data

When you use our calculators, we process the queries and inputs you provide to generate results. If you are signed in, your calculation history and saved calculations are stored in our database so you can access them later. Calculations performed without signing in are not stored.

5. Google AdSense and Advertising

We use Google AdSense to display advertisements on our website. Google AdSense uses cookies to serve ads based on your prior visits to our website and other websites on the internet. 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. Alternatively, you can opt out of third-party vendor cookies by visiting the Network Advertising Initiative opt-out page.

6. AI and Data Processing

Our calculator service uses artificial intelligence (AI) to interpret natural language queries and generate calculation results, step-by-step explanations, and scenario comparisons. Your queries are sent to our server and processed through an AI model. We do not use your personal calculation queries to train AI models. Query data may be temporarily logged for debugging and service improvement purposes.

We do not sell your personal information. We may share your data with the following third parties only as necessary to operate our Service:

• Authentication providers — to verify your identity when you sign in
• Cloud infrastructure providers — to host our website and database
• Google AdSense — to serve advertisements (see Section 5)
• Analytics services — to understand website usage patterns

8. Data Security

We implement appropriate technical and organizational measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. These measures include encrypted data transmission (HTTPS), secure authentication tokens, and access controls on our database systems. However, no method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.

9. Data Retention

We retain your account information and calculation history for as long as your account is active. You may delete individual calculations or your entire calculation history from your dashboard at any time.
