 "summary": "Shopify app from Effective Apps that adds customizable warnings — Prop 65 labels, shipping-delay alerts, age-verification and withdrawal disclaimers — to product, cart and checkout pages, as text or pop-ups, targeted globally or by product, collection, country or US state. On the App Store since December 2019.",
 "best_for": "shopify merchants who know exactly which notice they need — a Prop 65 label, a shipping-delay alert, an age-verification disclaimer, a we-no-longer-ship-here message — and want it on the right products, collections or countries without touching theme code, for $6.99 a month or nothing at all if one plain warning will do",
 "skip_if": "you are on a standard Shopify plan and specifically want the checkout blocked or a warning shown on the Checkout page: both are Plus Plan features and the Plus Plan is for Shopify Plus stores, so the capability the app's name advertises is not available to you at any price here. Also skip it if you sell off Shopify, or if what you actually need is consent and privacy management — cookie banners, consent records, data-subject requests — rather than a notice on a page.",
 "honest_knock": "The app is called Warn: Warnings Checkout Blocks, and blocking checkout is the one thing most readers of this listing cannot buy at the advertised price. Checkout blocking, and showing a warning on the Checkout page at all, sits on the Plus Plan at $12.99 a month — and that plan says, in the App Store's own words, that it is for Shopify Plus stores. The $6.99 Premium plan says the opposite: for all stores except Shopify Plus. So the two tiers are not a small ladder and a big one, they are two different audiences, and which one you may buy is decided by your Shopify subscription rather than by how much warning you need. If you are on a standard Shopify plan and came here to stop a checkout, read the plan labels before you install.\n\nThe second thing to be clear about is what the app does and does not take off your hands. It renders the notice, targets it by product, collection or country, and styles it to your store. It does not tell you what Proposition 65, a GDPR withdrawal notice or an age-verification disclaimer has to say in your jurisdiction, and it does not keep that wording current when the rule changes. The compliance language stays your problem and your liability; this is the display layer for it.",

Free gives you one textual warning across unlimited products, with the styling, per-product targeting and per-country targeting included. Premium is $6.99 a month or $41.94 a year, and the annual figure really is half of twelve monthly payments. It lifts the cap to unlimited warnings, notes and pop-ups, adds cart and checkout warnings, targeting by product or collection, and US-state geo-targeting on top of country targeting — but the plan is labelled for all stores EXCEPT Shopify Plus. Plus Plan is $12.99 a month or $77.94 a year, again exactly half of twelve monthly payments, and it is the Shopify Plus plan: the same feature list, plus warnings shown on the Checkout itself and the rule that lets a warning block checkout when configured. Both paid plans carry a 7-day free trial.",

  "why": "They are answers to different questions that both get filed under compliance. Consentmo is consent and privacy management: cookie banners, GDPR and CCPA consent records, data-subject requests — the paperwork side. Warn is the notice itself, placed on a product, cart or checkout page and targeted by product, collection, country or US state. If your problem is a Prop 65 label on 40 products or a shipping-delay banner for two countries, Warn is the narrower and cheaper fit at $6.99 a month. If your problem is proving what a visitor consented to, a warning app does not address it at all. The one place they meet is checkout blocking, and there Warn's answer depends on your Shopify plan rather than on the app."
