Privacy Policy

1. What stays on your device

Your recordings, transcripts, preparation notes, practice history and settings are saved only in your browser (IndexedDB and localStorage). They are not sent to our servers.

You can delete a record from the History page, or delete everything by clearing this site's data in your browser settings.

2. Microphone and speech recognition

The microphone is used only while you are practising, after you press the start button, and only with your browser's permission.

Transcription uses your browser's built-in speech recognition. Depending on the browser, your voice may be sent to the browser maker's service to be converted to text (for example, Google for Chrome). That processing is covered by the browser maker's privacy policy. We do not receive your audio.

3. Cookies and analytics

The site uses one cookie (NEXT_LOCALE) to remember the language you chose. We do not use advertising cookies or tracking tools.

4. Contact form

When you send the contact form, the information you enter (category, sender type, name, organisation, email address and message), your display language and — for bug reports — your browser details are delivered to us by email through Web3Forms.

We use this information only to reply to you and improve the site. We do not sell it or share it with others, and we delete it when it is no longer needed.

5. Support (donations)

Payments are processed by Ko-fi and its payment partners (such as PayPal or Stripe). We never see your card details. We may receive the name and message you choose to share on Ko-fi. Ko-fi's privacy policy applies.

The Support page shows Ko-fi's support panel embedded from ko-fi.com, and the ☕ button opens the same panel when you press it a second time. When the panel is shown, your browser connects to Ko-fi, and Ko-fi may use its own cookies.

6. Sharing and AI feedback

Share buttons open the service you choose (such as X, LINE or Facebook). Nothing is sent until you post there, and that service's policy applies.

“Copy for AI feedback” only copies text to your clipboard. If you paste it into an AI service, that service's policy applies.

7. Hosting

The site is hosted on Vercel. Like most websites, the hosting provider may automatically record basic access logs (such as IP address, browser type and time of access) for security and operation.

8. Changes

We may update this policy. The date at the top shows the latest version.
