Privacy Policy

What this site is

Student Acer is a free study guide library. You can browse, search, and download PDF study guides without creating an account or providing any personal information. An optional account lets you upload guides, share practice sets, comment, and message friends.

Information we collect

We don't require an account to use this site, and we don't collect names, emails, or other personal details from visitors browsing or downloading guides.

If you create an account, we store your username, your email address, and a hashed (never plain-text) password. Your email is used only to verify that it's yours with a one-time code and to help you get back into your account; it is never shown publicly or sold. Verification emails are sent through our email provider, Resend. Anything you add to your profile (a picture, the classes you're taking, and an optional bio) is shown publicly on your profile page, and you can change or remove it any time in Settings. We also ask whether you're a student or a teacher and, for students, your grade. That answer is private: only you and the site admin can see it, and you can change it in Settings.

If you sign in with Google, Google shares your email address, your name, and an account ID with us. We use the email and ID only to create and sign in to your account (the name is just a starting suggestion for your username). We don't get your Google password or access to anything else in your Google account, and we don't store your Google profile picture.

Our web server and hosting provider automatically log standard technical information (such as IP address, browser type, and pages requested) for security and operational purposes, as is standard for any website.

We use Vercel Web Analytics to count page views and see which pages are popular. It doesn't use cookies, and it only reports aggregate numbers, not anything that identifies you.

Cookies

The site itself sets one cookie: a signed, encrypted session cookie that keeps you signed in to your account (and protects forms against cross-site request forgery). It's only needed for signing in; browsing and downloading guides works without it.

This site may also display advertising served by Google AdSense. Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this or other websites. You can learn more about how Google uses data and manage your ad personalization settings at policies.google.com/technologies/ads and adssettings.google.com.

Visitors in the European Economic Area, the UK, and Switzerland are asked for consent before Google uses cookies for ads, and can change that choice at any time.

Third-party links

Study guide PDFs and pages on this site may reference third-party works (books, authors, curricula) for educational context. This site is not responsible for the content or privacy practices of any external site linked from here.

The SAT practice pages include an optional graphing calculator from Desmos. It loads from desmos.com only when you open it.

Deleting your account

You can delete your account yourself in Settings, which removes your email, password, profile, friends and messages and leaves any public study guides, practice sets, comments and chatroom posts up under the name “deleted user.”

Children's privacy

You must be at least 13 years old to create an account. We don't knowingly collect personal information from children under 13, and if we learn that an account belongs to someone under 13, we'll delete it. Browsing and downloading guides doesn't require an account or any personal information.

Changes to this policy

This policy may be updated from time to time, for example as advertising or analytics tools are added. The “Last updated” date above reflects the most recent change.
