Privacy policy

Last updated November 12, 2026

This policy explains what information voicechange.io ("we", "us") collects when you use the site at https://voicechange.io, why, and what choices you have. The short version: there are no accounts, we don't ask for your name or email, your audio is used only to make your result, and the site shows ads from Google and measures usage with PostHog, both of which use cookies. The desktop app keeps your audio on your computer.

Information we collect

Audio and text you submit

When you record, upload a file or song, or type text for text to speech, we receive that audio or text and process it on our own servers to produce your result. We do not use it to train the public voices in the catalog, and we do not sell it.

  • Input files are stored temporarily while your job runs and deleted when it finishes.
  • Results (the converted audio, and the video version for sharing) are stored so you can play, download and share them. Anyone you give a share link to can open that result. You can ask us to delete a result at any time.
  • Voice training recordings are used only to train your private voice model and are deleted as soon as training finishes. The trained model is kept until you delete it in the "Your voice" tab.
  • Voice requests you type into the "Can't find a voice?" box are stored so we can review them.

A random browser ID

The first time you visit, your browser is given a random identifier stored in a cookie called clientId. It lets the site show your recent results and your trained voices, and route job updates back to your browser. It is not linked to your name, email or any other account. It expires after one year; clearing your cookies removes it.

Usage and technical data

Like most websites, our servers log basic request information (IP address, browser type, the pages and files requested, and timestamps) to keep the site secure and working. We also record basic job information (which voice and mode were used, file length, and whether the job succeeded) to fix problems and decide which voices to improve. Logs are kept for a limited time.

Advertising and cookies

voicechange.io is free because it shows ads served by Google AdSense. Google and its partners use cookies and similar technologies to serve ads based on your prior visits to this website and other websites, and to measure ad performance.

  • Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
  • You can opt out of personalized advertising by visiting Google's Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info.
  • Learn more about how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites.

Visitors in the European Economic Area, the UK and Switzerland are asked for consent before personalized ads are shown, through a consent message provided by Google. You can change your choice at any time from that message.

Usage analytics

We use PostHog to understand how the site is used: which pages are visited, which buttons are clicked (for example the desktop app download button), the referring site, your browser and device type, and an approximate location derived from your IP address. PostHog stores a random identifier in a cookie and local storage so repeat visits can be counted, and it may record anonymized replays of page interactions with form inputs masked. We use this only to improve the site; we do not use it for advertising. You can block it with any common tracker blocker, and clearing your cookies resets the identifier.

The VoiceChange desktop app

The desktop app changes your voice on your own computer. Your audio is never sent to us or anyone else.

To learn which features are used and how well the app runs, the app sends anonymous usage events to PostHog: that the app was opened, when the voice changer is switched on or off, which voice and delay setting were used, how long it ran, the measured delay, CPU use and audio dropouts, plus the app version, operating system and processor type. Each install has a random ID that is not linked to you, your browser ID or any account. The app never sends audio, your microphone or speaker names, or your files. You can switch this off at any time with "Usage stats" at the top of the app window.

Other services we use

  • Cloudflare R2 stores result files.
  • Font Awesome serves the icons used on the site, which means your browser requests files from its servers.
  • Google AdSense serves ads, as described above.
  • PostHog provides the usage analytics described above, for the site and the desktop app.
  • Google Fonts serves the typeface used on the desktop app download page.

We do not share your audio, text or browser ID with anyone else, except where required by law.

Children

The site is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has uploaded personal information, contact us and we will delete it.

Your choices and rights

Because there are no accounts, we hold very little that identifies you. You can:

  • delete a trained voice yourself from the "Your voice" tab;
  • clear your cookies to reset your browser ID and history;
  • ask us to delete specific results or anything else linked to your browser ID;
  • opt out of personalized ads using the links above;
  • switch off the desktop app's usage stats from the app window.

Depending on where you live (for example under the GDPR in Europe or the CCPA in California), you may have rights to access, correct, delete or object to the processing of your personal information. To use any of these rights, email us. Include your browser ID (shown in the clientId cookie) or a share link so we can find the right data.

Security

The site is served over HTTPS and files are stored with access controls. No system is perfectly secure, so please don't upload recordings containing sensitive personal information.

Changes to this policy

We may update this policy as the site changes. The date at the top shows when it was last updated.
