Privacy
AudioSpeed is a free static calculator. The listening-time math runs in your browser. The hours, minutes, and playback speed you type are not sent to a server by this site's own script. This page describes the other services the pages do use. It is a plain-language notice about those services. It is not a legal certification, and it does not claim GDPR, CCPA, or any other compliance program.
Google Analytics 4
If you choose Accept, the site loads Google Analytics 4 with measurement ID G-X0RVS4D5VV from googletagmanager.com. Google may set cookies, including cookies whose names start with _ga, and may receive information such as the page you open, general browser and device data, and an approximate location derived from your IP address. Google explains Analytics collection in its Analytics privacy disclosures and in the Google Privacy Policy.
If you choose Decline, this site does not add that tag. The choice is saved in this browser under the localStorage key audiobook-analytics-choice. Clearing site data for this site removes the saved choice. Declining does not delete information Google may already have from an earlier accepted visit, and it does not stop the hosting, font, or stylesheet requests below.
No analytics choice is saved in this browser yet.
Cookies and browser storage
The calculator does not need an account cookie. The analytics choice uses localStorage, which stays in this browser but is not itself a cookie. Google Analytics may set cookies only after you accept. Vercel, Google Fonts, or the Tailwind CDN may keep their own logs or cookies. This site does not control those systems, and this on/off choice is not a full consent-management platform.
Hosting
The site is hosted by Vercel. When your browser requests a page, Vercel receives ordinary connection data such as IP address, user agent, and the requested URL, and it may keep server logs. See the Vercel privacy policy.
Fonts and styles
Pages load Plus Jakarta Sans, Inter, and Material Symbols from Google Fonts (fonts.googleapis.com and fonts.gstatic.com). Your browser contacts Google to fetch those font files. Pages also load the Tailwind CSS browser build from https://cdn.tailwindcss.com so the layout can be styled. That request can expose your IP address to the CDN. These requests are not gated by the analytics choice, because the page uses them to render.
What this site does not do
The calculator does not ask you to upload audio or create an account. This site does not show ads and does not use Google AdSense. Nothing on this page promises that no data is processed. The length and speed you enter stay in the page script unless some other script on your own browser sends them elsewhere.
