VocalRangeCalculator.com uses browser-based tools that may process microphone input, pitch information, test results, and user preferences. This page explains, in plain language, how those features handle data and what users can control.
Our goal is to be transparent about the difference between microphone access, local browser processing, recording, uploading, browser storage, and normal website infrastructure.
Microphone Access and Audio Processing
Some tools on VocalRangeCalculator.com require microphone access so they can analyze live audio.
Microphone permission allows your browser to provide audio input to the selected tool. It does not automatically mean every tool handles that audio in the same way.
Our microphone-based tools use different processing methods:
- some process audio locally in the browser
- some may record or upload audio as part of their function
- we do not currently use an external audio-processing API
Because implementation can differ between tools, you should refer to the individual tool page for feature-specific information where available.
We do not send vocal test results to Google Analytics or another analytics service.
Local Browser Processing
Where a tool performs processing locally, calculations and analysis can happen within your browser rather than through an external audio-analysis service.
This may include tasks such as:
- detecting pitch
- converting frequency to musical notes
- calculating range
- displaying recent results
- saving tool preferences
Local processing can reduce the amount of information that needs to leave your device, but it should not be interpreted as a guarantee that no website-related data is processed elsewhere.
For example, normal website requests still involve the hosting infrastructure required to deliver the page.
Audio Recording and Uploads
Not every microphone tool on VocalRangeCalculator.com has identical behavior.
Some tools may record or upload audio when required for the feature to work. Other tools may analyze live input locally without creating an uploaded recording.
We do not currently send audio to an external audio-analysis API.
When a tool records or uploads audio, its handling should be considered separately from tools that perform local-only processing. We aim to describe significant differences on the relevant tool or privacy pages rather than making one blanket claim for every microphone feature.
Browser Storage
VocalRangeCalculator.com uses localStorage for certain tool results and preferences.
Depending on the feature, browser storage may be used to remember information such as:
- recent results
- tool settings
- user preferences
- values needed to improve continuity between visits
localStorage is stored within your browser profile on your device. It is different from a server-side account or database.
Locally stored information may disappear if you:
- clear browser or site data
- use private or incognito browsing
- switch browsers
- switch devices
- configure your browser to remove stored data automatically
You can generally remove this information by clearing site data for VocalRangeCalculator.com through your browser settings.
For more information about browser storage and cookies, see our Cookies Policy.
Analytics and Advertising
VocalRangeCalculator.com does not currently use Google Analytics.
We also do not currently use Google AdSense or another active advertising platform.
Because Google Analytics is not currently active, we do not send vocal test results to Google Analytics.
Affiliate tracking is also not currently active.
If our analytics, advertising, affiliate, or tracking practices change in the future, the relevant privacy and cookie information should be updated to reflect the new implementation.
Cookies and Consent
VocalRangeCalculator.com does not currently operate a cookie/CMP consent banner.
The absence of a consent banner does not mean the site has no browser storage. As described above, some features use localStorage for results and preferences.
Our Cookies Policy explains the current use of browser storage and related technologies in more detail.
Hosting and Server Information
VocalRangeCalculator.com is hosted with Hostinger.
Like most website hosting providers, hosting infrastructure may process technical information necessary to deliver and secure the website. Depending on normal server operation, this may include information such as:
- IP address
- requested page or resource
- request time
- browser or device information
- server, error, or security logs
These infrastructure logs are different from a vocal-range result or microphone recording.
We do not describe normal website hosting as “zero data collection,” because serving a website generally requires some technical request information to pass through hosting infrastructure.
Contact Messages
If you contact VocalRangeCalculator.com, messages are handled through direct email.
The information contained in an email is therefore processed through the email systems involved in sending and receiving that message.
Avoid sending passwords, payment information, medical records, or other highly sensitive information through ordinary contact email unless specifically necessary.
For general questions, corrections, or technical issues, use our Contact Us page.
How You Can Control Microphone and Local Data
You remain in control of several browser-level permissions and storage settings.
You can:
- deny microphone access
- revoke microphone permission after granting it
- select a different microphone where supported
- close or reload a page to end an active microphone session
- clear stored site data
- use private browsing if you do not want browser storage to persist
- use manual-input tools where available
Most modern browsers also display some form of indicator while a website is actively accessing the microphone, although the exact design varies by browser and device.
If microphone access is not working correctly, see our Troubleshooting guide.
Security Measures and Limitations
We aim to limit unnecessary data handling and to describe our tools accurately.
However, no website, browser, network connection, device, or storage system can be guaranteed to be completely secure.
We therefore do not claim that:
- the website is impossible to compromise
- browser storage carries zero risk
- data can never be intercepted
- every device behaves identically
- every tool has the same privacy characteristics
Users should also take reasonable precautions on their own devices, including keeping browsers and operating systems updated and avoiding untrusted extensions or software.
Data Security and Tool Results
A vocal result may look precise, but the data behind it can be affected by microphone quality, background noise, browser processing, technique, and other factors.
Data security and measurement accuracy are separate issues.
For information about the reliability and limitations of vocal testing, see Vocal Range Test Accuracy.
