Privacy Policy

Effective date: November 11, 2026

1. Who we are

ClassroomJoe makes English-learning apps and this website, classroomjoe.com. ClassroomJoe is run by Mr. Joe, an adult-school ESL teacher in California. In this policy, "we" and "us" mean ClassroomJoe.

This policy covers classroomjoe.com and the ClassroomJoe apps, including ClassroomJoe English, Idioms, Citizenship, Sound Coach, and our vocabulary apps. KK's Word Quest, our app for children and families, has its own rules, described below.

2. What we collect

When you visit this website

• Basic visit information. Like almost every website, our web host keeps standard server records when you visit: your IP address, browser type, the pages you open, and the date and time. We use these only to keep the site running and secure.
• Fonts. Our pages load their fonts from Google Fonts. When they load, Google receives your IP address and browser information.
• This website has no account, no log-in, and no advertising.

When you email us or join our mailing list

• Your email address, and anything you choose to write to us, such as your name or question.
• Our mailing-list service may also record whether an email was delivered or opened, so we know our emails arrive.

When you use our apps

• No account. You do not create an account or give us your name, email, or phone number to use the apps.
• Your progress and settings (lessons finished, scores, streaks, your language choice) are saved only on your phone. We do not receive them.
• Microphone. Some lessons ask you to speak. The app asks your permission first, and you can say no and still use the other lessons. Your voice is used only at that moment, to check your pronunciation. We do not record, keep, or receive your voice. To turn speech into text, the app may use your phone's built-in speech service (Google on Android, Apple on iPhone), which follows Google's or Apple's own privacy policy.
• Adult School finder. If you type a ZIP code to find an adult school, the search happens on your phone. We do not receive your ZIP code or your location.
• App stores. When you download an app, Google Play or the Apple App Store handles the download and any reviews. They share only summary information with us, such as how many people installed an app, crash reports, and your phone model. They do not tell us who you are.
• The apps do not collect your contacts, photos, exact location, or identity, and do not show ads.

3. How we use information

• To run, fix, and improve our website and apps.
• To answer your questions and messages.
• To send ClassroomJoe news, only if you signed up. Every email has an unsubscribe link.
• To keep our services safe and to follow the law.

4. We do not sell or share your information

We do not sell your personal information. We do not share it with anyone for advertising, and we do not use it to build profiles about you. This has been true for the past 12 months.

5. Companies that help us

A few companies help us run ClassroomJoe. They may handle some information for us, and only to provide their service:

• Our web host, which runs classroomjoe.com.
• Our email provider, which delivers our email.
• Our mailing-list service, which stores the list and sends our newsletter, if you signed up.
• Google Fonts, which provides the website's fonts.
• Google Play and the Apple App Store, which deliver our apps.

We may also share information if the law requires it, to protect someone's safety, or if ClassroomJoe is ever transferred to someone new, who would have to follow this policy.

6. Cookies, tracking, and Do Not Track

We do not use advertising cookies or trackers on our website or in our apps, and we do not track you across other websites or apps over time. We do not allow other companies to do that tracking through our website or apps.

Do Not Track: Some browsers can send a "Do Not Track" signal. Because we do not track you across websites, our website and apps work the same whether or not that signal is on. We also honor the Global Privacy Control signal as a request not to sell or share your information, which we already do not do.

7. How long we keep information

• Emails you send us: as long as needed to help you, and no more than 2 years after our last message, unless you ask us to delete them sooner.
• Mailing list: until you unsubscribe or ask us to remove you.
• Website server records: kept by our web host for a short time, normally no more than 90 days.
• App progress: stays on your phone until you delete it or remove the app.

8. How to delete your information

• In the apps: uninstall the app, or use "Reset my progress" in the app settings. This deletes your progress from your phone. We do not have a copy.
• Mailing list: click "unsubscribe" in any email, or email us.
• Anything else: email with the subject "Delete my data." We will delete what we have within 30 days and tell you when it is done.

9. How we protect information

Our website uses a secure connection (https). We keep the information we hold to a minimum, use trusted service providers, and protect our accounts with strong passwords and two-step sign-in. No system is perfectly secure, but if a problem ever affects your information, we will tell you as the law requires.

10. Your California privacy rights

We are based in California and we follow California's privacy laws, including the California Online Privacy Protection Act. Wherever you live, you can ask us to:

• Know what personal information we have about you and how we use it.
• Get a copy of it.
• Correct it if it is wrong.
• Delete it.
• Not sell or share it. We already do not sell or share it.

To make a request, email . You can also have someone you trust make the request for you. We may ask a simple question to confirm the request is really from you. We will reply within 45 days. We will never treat you differently for using these rights.

"Shine the Light": California residents can ask whether we shared personal information with other companies for their own marketing. We do not.

11. Children

ClassroomJoe English and our other learning apps are made for adults. They are not made for children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has sent us personal information, email us and we will delete it.

KK's Word Quest is made for children to use with their parents. It does not ask for or collect any personal information from children. It will have its own privacy notice, written for families, before it is released.

12. New features and changes to this policy

If we add a feature that uses information in a new way, such as an optional account or progress saved online, we will update this policy first, explain the change in the app, and ask your permission where the law requires it. The effective date at the top shows when this policy last changed. We will not use information we already have in a new way without telling you.

13. Contact us

Questions or requests about your privacy:

We read every message and reply within a few days.
