API

StoreKit2.getProduct(productId, success, error)

Fetches product details from the App Store.

StoreKit2.getProduct("your_product_id", function(product) {
    console.log(product.title);       // "My Subscription"
    console.log(product.price);       // "$4.99"
    console.log(product.description); // "Unlock all features"
    console.log(product.priceValue);  // 4.99
}, function(err) {
    console.error(err);
});

StoreKit2.purchase(productId, success, error)

Initiates a purchase. Shows the App Store purchase dialog.

StoreKit2.purchase("your_product_id", function(transaction) {
    console.log(transaction.transactionId);
    console.log(transaction.purchaseDate);
    console.log(transaction.expiresDate);
    localStorage.appVersion = "full";
}, function(err) {
    if (err === "USER_CANCELED") {
        // User tapped cancel
    } else {
        alert("Purchase failed: " + err);
    }
});

StoreKit2.isOwned(productId, success, error)

Checks if the user currently owns/has an active subscription. No server needed.

StoreKit2.isOwned("your_product_id", function(result) {
    if (result.owned) {
        localStorage.appVersion = "full";
        console.log("Expires: " + result.expiresDate);
    } else {
        localStorage.appVersion = "free";
    }
}, function(err) {
    console.error(err);
});

StoreKit2.restorePurchases(success, error)

Syncs purchases with the App Store. May prompt for Apple ID sign-in.

StoreKit2.restorePurchases(function() {
    StoreKit2.isOwned("your_product_id", function(result) {
        if (result.owned) {
            localStorage.appVersion = "full";
            alert("Subscription restored!");
        } else {
            alert("No active subscription found.");
        }
    }, function(err) {
        console.error(err);
    });
}, function(err) {
    alert("Restore failed: " + err);
});

How it works

This plugin uses StoreKit 2 which:

• Doesn't need a receipt validation server — Transaction.currentEntitlements gives you verified ownership status locally
• Automatically finishes transactions — no more unfinished transactions piling up in the queue
• Handles renewals and cancellations — isOwned() always reflects the current subscription state
• No login prompts on app launch — isOwned() reads from local data without contacting Apple
