Privacy Policy
We want you to understand what kind of information may be collected when you use the Vocal Range Test, and how we try to protect it.
The site may use cookies and similar technologies to keep the service running smoothly and to understand basic usage patterns. Details about what types of cookies we use and why are described in our separate Cookie Policy. You can control cookies in your browser settings, but doing so may affect how well some features work.
Like most websites, we may collect technical information such as pages visited, basic browser and device details, timestamps and error logs. Our goal is to process voice data in your browser whenever possible and to avoid storing raw audio on our servers. If we ever decide to use anonymised statistics or aggregated data for research or improvement, we will clearly explain what we are collecting and why.
We use the information we collect primarily to: 1) keep the site stable and fix bugs; 2) understand which features are useful so we can improve them; 3) detect and prevent abuse or security issues. We do not sell your personal data or share it with third parties for their own marketing purposes.
Access to logs and configuration data is limited to the small number of people who need it to run the project. We aim not to keep detailed logs for longer than necessary, and to aggregate or delete data once it is no longer needed. However, no system connected to the internet can be guaranteed 100% secure. If a serious incident ever occurs, we will be as transparent as we reasonably can about what happened and what we are doing in response.
In the future we may rely on third‑party hosting, analytics or embedded tools to help run the site. When we do, we aim to share only the minimum technical information required, and those services will handle that data under their own privacy policies. Whenever a specific external service is important to how the Vocal Range Test works, we will try to mention it clearly in our documentation or on the site.
Technical logs such as server and error logs are kept only as long as we genuinely need them for troubleshooting, security and understanding basic usage. After that, they are deleted or turned into aggregated statistics that no longer reasonably identify individual users. Exact retention periods may vary based on infrastructure and legal requirements, but our intent is to avoid keeping detailed logs "just in case".
You can limit or block cookies in your browser, use tracking‑protection features, or choose not to use the site if you are not comfortable with this policy. At our current scale we do not operate individual account dashboards or formal data‑access workflows, but if that changes we will update this page. If you live in a region with specific legal rights around data access or deletion, you can contact us and we will do our best, within our constraints, to respond appropriately.
We may update this Privacy Policy when the law changes or when our technology and practices evolve. When that happens, we will update the "lastUpdated" date and, for major changes, do our best to highlight them on the site. Continuing to use the Vocal Range Test after a change goes live will be treated as acceptance of the updated policy.
If you have questions about how we handle data, you can reach us through the contact form described in the About Us section. We cannot promise legal advice or instant responses, but we do care about getting this right and will read what you send.
