Privacy Policy

Last updated: November 15, 2026

All About Music Theory (“we”, “us”, “our”) runs allaboutmusictheory.com, a free resource for learning music theory. This policy explains what information we collect when you use the site, how we and our partners use it, and the choices you have.

If you have any questions about this policy, email us at privacy@allaboutmusictheory.com.

Information we collect

When you browse the site. You can read every lesson and download our worksheets without telling us who you are. When you visit, we and the services we use automatically collect some information about your device and how you use the site: your IP address, browser and device type, operating system, approximate location (such as your country or city), the pages you visit, how long you stay, the page that linked you to us, and the date and time. Some of this comes from our hosting provider’s server logs, and some is collected through cookies and similar technologies (see Cookies and similar technologies below).

When you contact us. If you email us, we receive your email address and whatever you choose to include in your message. We use it to reply to you.

If you create an account. The site doesn’t have user accounts today. If we add them, we’ll collect what we need to run your account: your name or a username, your email address, and a password (stored only in encrypted, hashed form, never as plain text). We may also save your lesson progress, quiz results and preferences so you can pick up where you left off.

If you buy premium content. Everything on the site is free today. If we offer paid lessons, courses or downloads in the future, payments will be handled by a trusted third-party payment processor. Your card details go directly to that processor; we never see or store your full card number. We keep a record of what you bought, when, and your billing country, so we can give you access, provide receipts and meet our tax obligations.

How we use your information

We use the information we collect to:

  • run, maintain and improve the site and its lessons;
  • understand how visitors find and use the site, through analytics;
  • show advertising, which may be personalized to your interests, and measure how well it works;
  • remember your preferences;
  • keep the site secure and prevent abuse;
  • answer your questions and support requests;
  • run your account and give you access to any content you’ve purchased;
  • send you emails you’ve asked for, such as account notices or a newsletter you signed up for;
  • meet our legal, accounting and tax obligations.

We’ll only send you marketing emails if you’ve opted in, and every one will include a link to unsubscribe.

Cookies and similar technologies

Cookies are small files stored on your device by your browser. We, and third parties working with us, may use cookies and similar technologies (such as local storage, pixels and web beacons) for these purposes:

  • Essential: to make the site work, for example to keep you signed in or keep it secure.
  • Preferences: to remember your settings and choices.
  • Analytics: to count visits and see which pages are popular and how people move around the site, so we can improve it.
  • Advertising: to show ads, limit how often you see the same ad, measure how ads perform, and in some cases show ads based on your visits to this and other websites.

Where the law requires it, for example in the European Union and the UK, we’ll ask for your consent before using cookies that aren’t essential, and you can change your choice at any time.

You can also block or delete cookies in your browser’s settings, though some parts of the site may not work properly if you do. To opt out of personalized advertising from many ad networks, visit aboutads.info or, in Europe, youronlinechoices.eu. You can manage Google’s ads at Google Ad Settings.

Third-party services

We use services from other companies to run the site. They may receive your IP address and information about your browser and device, and some may set their own cookies. They include:

  • Hosting and delivery providers, which serve the site’s pages.
  • Embedded content, such as fonts from Google Fonts and the audio and video players (like SoundCloud and YouTube) in our lessons.
  • Analytics providers (such as Google Analytics), which help us understand how the site is used.
  • Advertising partners (such as Google AdSense), which may display ads on the site and use cookies to show ads based on your visits to this and other websites.
  • Affiliate programs: some links to music, books or gear may earn us a commission if you buy something, and the seller may record that you came from our site.
  • Payment and email providers, which process payments and send emails on our behalf.

Each of these companies has its own privacy policy, which governs how it handles the information it collects. We don’t control the cookies or tracking that third parties use. Our lessons also link to other websites; we aren’t responsible for their content or their privacy practices.

How we share information

We may share information with the service providers that help us run the site, and with analytics and advertising partners, who may also collect it directly through cookies as described above. We may also disclose information if the law requires it, to protect the rights and safety of our users or the site, or as part of a merger, sale or transfer of the site.

Under some laws, such as those of certain US states, sharing information with advertising partners for personalized ads can count as “selling” or “sharing” personal information. If those laws apply to you, you can opt out by emailing us or by using the opt-out tools listed above.

How long we keep it

We keep personal information for as long as we need it for the purposes in this policy. Log and analytics data are kept for a limited period, and third parties keep the data they collect according to their own policies. If you have an account, we keep your information while the account is open; when you delete it, we delete your personal information, except for records we must keep for legal or tax reasons, such as purchase receipts.

Keeping your information safe

The whole site is served over an encrypted (HTTPS) connection, and we limit who can access the information we hold. No method of storing or sending data over the internet is completely secure, but we take reasonable steps to protect your information.

Your rights and choices

Depending on where you live, you may have the right to:

  • ask what personal information we hold about you and get a copy of it;
  • correct information that is wrong or incomplete;
  • ask us to delete your information or close your account;
  • object to, or ask us to limit, how we use your information;
  • opt out of personalized advertising, or of the “sale” or “sharing” of your information;
  • withdraw consent you’ve given, such as unsubscribing from emails.

To make any of these requests, email privacy@allaboutmusictheory.com. We’ll answer within 30 days. If you’re in the European Union or the UK, you also have the right to complain to your local data protection authority.

Children’s privacy

Music students of all ages use All About Music Theory, and anyone can read the lessons without creating an account or telling us who they are. We don’t knowingly collect personal information from children under 13 (or the minimum age in your country). If we add accounts, children under that age will need a parent or guardian’s permission to sign up. If you believe a child has given us personal information, please email us and we’ll delete it promptly.

International visitors

Our service providers may store and process information in countries other than your own, including the United States. Where the law requires it, we make sure appropriate safeguards are in place.

Changes to this policy

We may update this policy from time to time, for example when we add new features or services such as accounts, premium content, analytics or advertising. When we do, we’ll change the date at the top of this page. For significant changes, we may also let you know in other ways, such as a notice on the site or an email to account holders. Continuing to use the site after a change means you accept the updated policy.
