Privacy Policy

Last updated: June 2026

This Privacy Policy explains how Reverb-Calculator.com collects, uses, and handles information when you visit or use this website. Reverb-Calculator.com is operated by Noah Bennett (contact available via the Contact page).

By using this website, you agree to the practices described in this Privacy Policy.

1. Overview

Reverb-Calculator.com is a free educational website providing browser-based room acoustics calculation tools and educational content about RT60 reverberation time, acoustic formulas, absorption coefficients, and room design.

Our approach to privacy:

We do not require user accounts or registration
We do not sell personal information to any party
We do not use advertising networks or behavioural tracking systems
The calculation tools perform local computation on typed numeric input — no audio, no sensor data, no data transmission
Data collection is limited to what is necessary to operate the website

2. Calculation Tools — No Data Captured

All calculation tools on Reverb-Calculator.com — the RT60 calculators using the Sabine and Eyring formulas — compute results from room dimensions and absorption coefficient values you type. These tools:

Do not use your microphone
Do not capture any audio from your device or environment
Do not access any device sensor
Do not transmit any data over the internet
Do not store your inputs or results
Do not make any network requests during operation

Despite being an acoustics website, this site does not perform acoustic measurement. All computation happens entirely within your browser’s JavaScript runtime. There is no data handling consideration for these tools.

3. Automatically Collected Information

When you visit Reverb-Calculator.com, limited technical information may be processed automatically by your browser or web hosting infrastructure — including IP address, browser type, device type, and basic server access logs. Used only for website functionality and security. Not used for advertising or user profiling.

4. Analytics

Reverb-Calculator.com may use basic analytics to understand aggregate traffic patterns — such as which pages are visited and what devices are used. Any analytics used collect only anonymised, aggregated data that does not identify individual users. No third-party behavioural analytics platforms are used.

5. Advertising

Reverb-Calculator.com does not use advertising networks, advertising cookies, or behavioural targeting technologies. There are no advertising cookies, no DoubleClick cookies, and no third-party advertising scripts on any page of this site.

6. Cookies

Reverb-Calculator.com does not use advertising or tracking cookies. Only essential functional cookies may be used where required for basic website operation and security.

Full details are in the Cookie Policy.

7. Information You Provide Voluntarily

If you contact Reverb-Calculator.com through the Contact page, we receive your email address and the content of your message. Used only to respond to your inquiry. Not shared with third parties, not used for marketing, not retained longer than necessary.

8. Third-Party Links

This website may link to external resources for educational reference — including acoustic standards organisations, published research, and reference data sources. We are not responsible for the privacy practices of external websites.

9. Data Security

Reasonable technical measures protect the website and voluntarily submitted information. The browser-based design of the calculation tools — in which all processing occurs locally with no data transmission — means user inputs are never exposed to server-side risk.

10. Children’s Privacy

Reverb-Calculator.com is intended for a general audience including acoustic engineering and architecture students. We do not knowingly collect personal information from children under the age of 13. If you believe a child under 13 has submitted personal information through the Contact page, please notify us via the Contact page so it can be removed.

11. Your Privacy Rights
