Promotions

After creating a promotion here

1. Stripe — go to dashboard.stripe.com/coupons, create a coupon with the same discount %, then create a Promotion code using your coupon code (e.g. BLACKFRIDAY26). Set the same end date.
2. iOS — in App Store Connect → your product → Subscription Offers, create an Offer Code batch. The app will show a "Redeem offer" button during the promo window.
3. Android — in Play Console → Monetise → your product → Offer details, create a promo code or a discounted price product.
4. When the promotion ends, deactivate the Stripe code so late attempts don't work.
