You never signed anything. You just clicked a button, or maybe just kept browsing. Whether that counts as a binding agreement depends entirely on which one you did — and courts draw a sharp line between them.
Clickwrap: you did something affirmative
A clickwrap agreement requires you to take a specific, active step — checking a box or clicking "I Agree" — after being presented with the terms. Courts consistently favor these: because the action leaves an unambiguous, timestamped record of assent, clickwrap agreements are widely recognized as valid and enforceable, similar to the long-established enforceability of software "shrink wrap" agreements.
Browsewrap: you did nothing at all
A browsewrap agreement relies on the mere fact that you used a website as evidence you agreed to its terms, typically linked somewhere in the footer with no click or checkbox required. This is the weaker form by a wide margin. In Nguyen v. Barnes & Noble (9th Circuit, 2014) — now the leading case on this — the court refused to enforce a browsewrap agreement because a footer link to the "Terms of Use," even placed prominently and near the checkout button, wasn't enough to give a reasonably prudent user actual notice of the agreement.
What actually satisfies "reasonable notice"
Courts assess the conspicuousness and placement of the terms link, any other notices given to users, and the website's overall design together. A link labeled clearly and placed directly in the path of a required action does far better than a link a user could complete their entire purchase without ever seeing. In Meyer v. Uber, a case the same circuit later decided differently from Nguyen, the court enforced the terms specifically because the screen put the agreement directly in front of the user with an explicit "by clicking, you agree" prompt — the opposite design choice from Barnes & Noble's quiet footer link.
A middle ground: sign-in wrap
A newer, increasingly common approach — sometimes called "sign-in wrap" or "scrollwrap" — presents the terms directly during signup or checkout, often requiring the user to scroll through or view them before an account or purchase can be completed, without necessarily requiring a separate checkbox. Courts have generally treated a well-designed version of this favorably, since it combines conspicuous presentation with the user's active progression through a flow specifically designed to surface the terms.
Why the specific person clicking also matters
A less obvious issue: if someone other than you — a reseller, a company representative acting on your behalf, an automated bot — is the one who actually clicked "I agree," the question becomes whether that person or process had the authority to bind you, and whether you personally ever saw the terms at all. A click by the wrong party can carry little to no legal weight, regardless of how clearly the terms were presented.
How to protect yourself as a user
- Take screenshots of the terms and the acceptance screen when you sign up for something significant — services change their interfaces, and you may need to prove what you actually saw and agreed to.
- Save a copy of the terms themselves at the time of signup, not just a link to a page that may later change or disappear.
- If a dispute later arises over what you "agreed to," check whether the sign-up process was genuinely clickwrap (an affirmative action) or a weaker browsewrap-style design — this matters for your legal position either way.
- Watch for continued-use language stating that using the service after a terms update constitutes acceptance — this can be enforceable if the update notice itself was conspicuous.
What this means practically
- Clickwrap agreements — an affirmative click or checkbox — are consistently enforced by courts; browsewrap agreements relying on mere site use are frequently struck down.
- The specific design of the sign-up or checkout flow, not just the presence of a terms link somewhere, is what courts actually examine.
- Save your own copy of terms and the acceptance screen at the time you sign up — this is your best evidence if a dispute arises over what you actually agreed to.
- Continued use of a service after a conspicuous update notice can itself constitute binding acceptance of the new terms.
