Privacy Policy

Last Updated: September 20, 2026

At Sphere Volume Formula (accessible from https://spherevolumeformula.com/), one of our main priorities is the privacy of our visitors. This Privacy Policy document contains types of information that is collected and recorded by Sphere Volume Formula and how we use it.

1. Information We Collect

Sphere Volume Formula is an open, free educational tool. You can use our calculators and access educational materials without creating an account or providing personal identification information.

Calculation Inputs: Numerical radius, units, and resulting computed volumes may be logged anonymously to optimize system performance and generate calculation statistics.
Contact Communications: If you contact us directly via our contact form, we receive your name, email address, and message contents.

2. Log Files & Server Information

Like most website hosting platforms (including Hostinger), Sphere Volume Formula follows a standard procedure of utilizing server log files. The information collected by log files includes internet protocol (IP) addresses, browser type, Internet Service Provider (ISP), date and time stamp, referring/exit pages, and possibly the number of clicks. These are not linked to any information that is personally identifiable.

3. Cookies and Web Storage

We use minimal cookies strictly necessary for core functionality:

Session Cookies: Temporary cookies used to preserve CSRF security tokens and authenticate administrative sessions.
Preferences: Browser local storage may be used to remember your preferred measurement units (e.g., cm or inches).

4. Data Security

We implement modern standard security practices, including prepared PDO SQL statements, SSL/TLS encryption, and password hashing with password_hash() for administrative accounts to protect all stored information.
