-* **Account data.** You do not need to create an account to use Common Voice. If you decide to create an account, we receive your username and avatar, if you submit one. Your email address is associated with your demographic and interaction data but is not shared to the public. We display leaderboards showing the number of recordings users make. You have the option whether or not you wish to appear on the leaderboards. You can delete your account at any time and your username and email will be removed.

Your use of Mozilla accounts is governed by the [Mozilla Accounts Terms of Service](https://www.mozilla.org/about/legal/terms/services/) and [Mozilla Accounts Privacy Notice](https://www.mozilla.org/privacy/mozilla-accounts/). Your email address is associated with your demographic and interaction data but is not shared to the public. We display leaderboards showing the number of recordings users make.

At any time, you may create a full account (as set forth above). If you do not create a full account upon completion of the Alpha or Beta testing, we will delete your email address within two weeks after the completion of each testing program. Certain types of participation in Beta testing (e.g. for ultra low resource languages) may not require an email login.
