Mayfield Learning

Last updated: June 3, 2026

The short version

The lessons are free and you can read them without an account.
If you create a free account, we store your name, email, and your learning progress, so we can save your place.
We send only the emails you would expect (verify your address, reset your password, and any newsletter you choose to join). No spam, ever.
We do not sell your identifiable personal information to advertisers or data brokers.
We may use and share aggregated or de-identified information, and if Mayfield is ever sold or merges with another company, your information may transfer as part of that deal (see “Business transfers” below).
You can access, export, or delete your account and data at any time.

What we collect

Account information. When you register, we store your name, email address, and a securely hashed password (we never see or store your actual password).

Learning progress. Which lessons you have started, completed, or saved, so we can show your progress and pick up where you left off.

Usage and technical data. Standard server logs and first-party, privacy-respecting analytics about how the lessons are used, so we can understand how people learn and make Mayfield better. We do not use third-party advertising trackers.

Cookies and analytics

When you log in we set a secure session cookie so you stay signed in. We use first-party analytics to see how the lessons are working and improve them; we do not use cross-site advertising trackers. By creating an account you agree to this Privacy Policy, including the first-party cookies and analytics described here, so signed-in members are not shown a separate cookie banner. For visitors who are not signed in, where the law requires it we ask for consent first. You can opt out of analytics at any time, and you can read every lesson without logging in.

How we use your information

To provide the service and save your learning progress.
To send the account emails you would expect (verification, password reset) and any newsletter you opt into, via our email provider, Resend.
To keep the site secure (for example, checking new passwords against known data-breach lists).
To understand how people learn and to improve and develop our lessons, content, features, and tools, including through aggregated and de-identified analysis.

Who we share it with

We share your information with the trusted service providers that run Mayfield on our behalf (hosting: Vercel; database: Neon; email: Resend), only as needed to operate the service. We may disclose information when required by law or to protect the rights, safety, and integrity of Mayfield and its users. We may share or sell aggregated or de-identified information that cannot reasonably be used to identify you. We do not sell your identifiable personal information to advertisers or data brokers.

Business transfers

Mayfield Learning is a business. If we are involved in a merger, acquisition, investment, financing, reorganization, bankruptcy, or a sale of some or all of our assets, your information may be transferred or sold to the parties involved as part of that transaction. We will require the recipient to honor this Privacy Policy, or we will give registered users notice before their information becomes subject to a materially different policy.

Your choices and rights

You can view, correct, export, or delete your account and associated data at any time, just email us. Deleting your account removes your personal information and progress from our active systems. Depending on where you live, you may have additional rights under laws such as the GDPR (EU and UK) or the CCPA and CPRA (California), including the right to access, delete, or port your data, and to opt out of the sale or sharing of personal information. To exercise any of these, email us, and we will honor verified requests.

Data retention and security

We keep your data while your account is active and as needed to run the service and meet legal obligations. Passwords are hashed, connections are encrypted, and access is limited. No system is perfectly secure, but we work to protect your information and minimize what we hold.

Children

Mayfield Learning is intended for adults and is not directed to children under 13. We do not knowingly collect personal information from children under 13, and we delete it if we learn we have. If you are under 18, please use Mayfield with a parent or guardian.
