Privacy Policy

1. Introduction

Welcome to Calzivo ("we," "our," or "us"). We are committed to protecting your privacy and providing a transparent overview of how we handle your data. Calzivo provides free online tools and calculators designed for speed, privacy, and simplicity.

By using our website (calzivo.com), you agree to the practices described in this Privacy Policy. If you do not agree with this policy, please do not use our services.

2. Information We Collect

We aim to collect as little information as possible. Because Calzivo is designed as a browser-first platform, the vast majority of your data processing happens locally on your device and never reaches our servers.

• Usage Data: We collect non-identifying technical information such as anonymized IP addresses, browser types, device categories, and page interaction patterns. This helps us optimize tool performance and site navigation.
• Tool Input Data: For standard calculators (e.g., math, health, finance), your inputs are processed entirely within your browser. We do not see, store, or log the specific values you enter into these tools.
• File Processing Data: For tools that require server-side logic (e.g., certain PDF or image conversions), files are transmitted via secure encrypted channels, processed in temporary volatile memory, and are not permanently stored.
• Communication Data: If you reach out for support, we retain your email address and message history solely to resolve your request.

3. How We Use Information

We use the information we collect to:

• Provide, maintain, and improve our tools and services.
• Monitor and analyze usage trends to enhance user experience.
• Respond to your comments, questions, and support requests.
• Protect the security and integrity of our website.

4. Cookies and Similar Technologies

We use cookies to improve your experience, remember your preferences, and analyze our traffic. For detailed information, please refer to our Cookie Policy.

5. Analytics

We use privacy-conscious analytics tools to monitor site health and popular features. These tools aggregate data to show us how many people use a specific calculator or if a page is loading slowly. We do not use analytics to track individual users across other websites or to build personal profiles.

6. Data Retention

We retain personal information only as long as necessary to fulfill the purposes outlined in this policy. Usage data is typically aggregated and anonymized. Communication data is kept as long as needed to provide support.

7. File Handling and Security

For tools involving file uploads (such as PDF converters or image compressors):

• Local Processing: Whenever technically feasible, processing happens in your browser (Client-Side).
• Server Processing: If a tool requires server resources, your file is uploaded to a secure, temporary environment.
• No Persistent Storage: We do not store your files. They are deleted automatically from our processing queue immediately after your download is ready, or within 60 minutes if the session is abandoned.
• No Manual Access: Our staff cannot and do not access the contents of the files you process.

8. User Rights

Depending on your location, you may have rights regarding your personal data, including the right to access, correct, or delete the information we hold about you. Since we do not require signups, we generally do not have identifiable accounts to manage.

9. Security

We implement standard security measures to protect your information. However, no method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.

10. Children’s Privacy

Calzivo is not intended for children under the age of 13. We do not knowingly collect personal information from children.

11. International Users

Our website is hosted in various regions. By using our services, you consent to the transfer and processing of your information in these locations.

12. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last Updated" date.
