Your policies are already free and already linked. What Shopify has no native version of is the tick box that makes somebody agree to them, and the reason this category is worth reading carefully is that the obvious way to build one has a hole in it.

A checkbox on the cart page stops the customer who goes through the cart page. It does not stop the ones who never see it, and Shopify puts a buy-it-now button on the product page itself, with express wallet buttons alongside it, skipping the cart entirely. The thing that closes that gap is a cart and checkout validation function, which runs server side, explicitly covers express checkouts including the major wallets, and cannot be bypassed by customers. A checkbox alone is presentation; the validation is the enforcement.

On checkout itself, the picture is plan-dependent. Shopify's own extension documentation uses an "I agree to the terms and conditions" checkbox as its example, and notes that the component does not come with required validation built in. It also states that extensions on the information, shipping and payment steps are available only on the top plan, so for most stores the checkbox lives on the cart and the enforcement lives in the function.

What to look for in a Axe Checkbox app

Whether express checkout is really covered: Test it rather than trusting the listing: put an item in the cart, use the buy-it-now button, and see whether anything asks you to agree. Every listing here claims compatibility, and this is the single feature the cheap builds get wrong.
What ends up on the order: Agreement is worth having only if it is recorded. The usual mechanism is a cart attribute, which carries over to the order and shows up in its additional details. Check what is stored, whether it includes a timestamp and which version of your terms was in force.
How the text is written and translated: The sentence beside the box is the agreement, so it should link to the real policy page and read as a sentence. If you sell in several languages, it has to exist in each of them.
How much friction you are adding: This is a deliberate obstacle in front of the buy button and it will cost some orders. That is the point when you need it and pure loss when you do not, so be clear about which situation you are in before installing.

Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn the badge, an app must meet Shopify's standards for safety, performance, ease of use, and proven usefulness: it cannot slow down the admin, storefront, or checkout, must integrate seamlessly into the Shopify admin, and must demonstrate quality through installs, reviews, and ratings over time. When comparing similar apps, preferring ones with the badge is a safe default. Learn more about the Built for Shopify badge →
