Privacy Policy

This site has no user accounts, so it never asks for your name, your email address or your payment details. Here is what it does keep, and what it never keeps.

What you enter into the tool

The tool on the homepage sends your text to the site's server only to turn it into audio. The text is not stored, not logged, and not used for anything else: it is discarded when the generation for your request finishes. The audio model runs on Cloudflare Workers AI, and the speech is generated by the Grok TTS model from xAI; this site is not affiliated with xAI.

The funnel log

To see which pages and steps get in the way, the site records a small event log. Each entry holds the event name (a page view, a generate click, a finished download), the page it happened on, the version of the site, and a random id that lives in one browser tab's sessionStorage, so the steps of one visit can be told apart. The log never receives what you type or paste, never receives your IP address, and never receives your browser or device details. While a page test is running (next section), an entry also carries the test's visitor id.

Page tests

From time to time the site shows two versions of part of a page, such as a headline, to see which one works better. To keep you on the same version from one visit to the next, the site then sets one cookie of its own, vid: a random id that says nothing about you and lasts up to a year. When the tested part of the page comes into view, the site records that id, which version it saw, the page, the version of the site, and whether the device was a phone or a computer. The same fact, which test and which version, is passed to pvuv.ai (see Analytics). When no test is running, the cookie is not set. Deleting it or blocking it changes nothing about how the tools work.

The traffic log

To see when search engines and AI assistants start sending people here, the site keeps a separate traffic log. Known crawlers are recorded with their IP address and user agent, so each visit can be checked against the IP ranges the crawler's operator publishes. For human visitors the log keeps much less: the page they loaded, the site that sent them, the country, and an anonymous number that changes every day — never the IP address and never browser details. Once a page has loaded, the page reports back once with the page address and nothing else. A visit that never reports back is counted separately as suspected automated traffic, kept out of the visitor counts.

Free limits

The tool is free, with a per-day allowance. To count it, the server keeps a salted hash of your IP address together with the date and a running total of your uses. The hash is kept for at most a month and is then deleted; the IP address itself is never stored. The limits in force right now are:

• Without an account: 20 uses a day, up to 1,000 characters each.
• Signed in with Google (free): up to 1,000 characters per use, 20 uses an hour, 5,000 characters a day and 50,000 characters a month.
• Free accounts on the same network share 10,000 characters a day.

Cookies and browser storage

There is no account to log into. The site sets one cookie of its own, vid, and only while a page test is running (see Page tests). Google Analytics and pvuv.ai (see below) set their own cookies to tell repeat visits apart. Two things live in your browser only: your light or dark theme choice, kept in local storage, and the random funnel session id described above, kept in sessionStorage and gone when the tab closes.

Analytics

The site uses Google Analytics to count visits and see which pages and tools get used. It receives the page address, your browser and device type, an approximate location derived from your IP address, and named events such as which tool was used and which button was clicked. It never receives what you type or paste into a tool, or the audio you create. Google processes this data under its own privacy policy; you can opt out with Google's opt-out add-on or a content blocker, and the tools keep working either way.

The site also uses pvuv.ai to count page views and visitors. It receives the page address, the referring page, your browser and device type and an approximate location derived from your IP address, and it sets its own cookies and local storage entries to tell repeat visits apart. While a page test is running it is also told which version of the page you saw. Like Google Analytics, it never receives what you type or paste into a tool, or the audio you create, and a content blocker turns it off without affecting the tools.

Third-party links

Some pages link to other websites. Their privacy practices are their own.

Changes

If this policy changes, the date at the top of the page shows the latest version. Anything that would mean keeping more of your data will be spelled out here before it happens.
