English Numbers has no accounts, no analytics and no cookies. Everything it remembers lives in your browser, and you can delete it in one click.
What is stored in your browser
The site uses local storage (not cookies) under these keys:
enl.settings.v1— your practice settings, and the interface language you were using when you last changed one.enl.history.v1— your last 50 sessions: topic, date, settings, each answer you typed with its outcome, how long the first answer took, and the error patterns.enl.mistakes.v1— the questions you got wrong, so you can retry them.enl.session.v1— a paused session, so you can continue it after a reload, a language switch or closing the tab; it is dropped when the session ends, when you start over, or after seven days.enl.probe— a one-character test entry, written and removed at once to check that storage works. It never holds your data.
What is never collected
- No cookies of any kind.
- No analytics or tracking scripts, and no third-party requests.
- No account, email address or name. The site never asks for a real phone number.
- Nothing you type is sent to a server. Pages and audio are static files.
If you report a question
The Report this question link opens your own mail app with a message you can read and edit before sending. The site itself sends nothing. If you send the message, the owner of the site receives your email address and what the message says: which question and clip, the accent and the interface language.
