Short version: the tools work inside your browser. We do not upload the text you type, the sound from your microphone or the files you open, and we do not use cookies, analytics or ads.
Processed on your device
- Text you type or paste is translated by code running in your browser. It is not sent to us.
- Sound, light and vibration are created in your browser.
- Downloads (MP3, WAV, TXT) are created in your browser and saved straight to your device. The MP3 encoder is a file loaded from this website, not from another company.
- Microphone: the audio decoder only asks for the microphone when you press "Listen with microphone". The sound is analysed live in your browser and is not recorded, saved or uploaded. Listening stops when you press Stop or leave the page.
- Audio and video files you choose in the audio decoder are read by your browser on your device. They are not uploaded.
Saved on your device
We use your browser's local storage (not cookies) to remember your sound settings, your light or dark mode choice and your trainer lesson. This data stays in your browser. You can delete it by clearing this site's data in your browser settings.
Share links
When you press "Share link", your message is placed in the link itself, after the # sign (for example …#t=hello). Browsers do not send the part after # to our server. But anyone you give the link to can read the message, and the app or chat you paste it into can see it too.
Our hosting provider
The website is served by Cloudflare. Like any web host, Cloudflare receives technical information needed to deliver pages and protect the site, such as your IP address, browser type and the pages requested. See Cloudflare's privacy policy. We have not turned on Cloudflare analytics for this site.
What we do not use
No cookies, no analytics or tracking scripts, no advertising, no accounts and no third-party fonts or scripts. If this changes, for example if ads are added, this page will be updated before the change goes live.
