## Private Play — product and campaign information (advertisement)

- Canonical product/offer page: https://saas-hikaku.com/offers/private-play/
- Private Play is an iPhone photo/video player for a user's own media, requiring iOS 17 or later. It combines full-screen swipe playback, Highlights that save video time ranges without duplicating the video, looping Highlights, favorites, and shuffle playback. Its product positioning is a carefully designed, comfortable playback experience; this is advertising copy, not an independent award or rating.
- Japanese App Store offer settings verified through ASC API on 2026-10-23: Monthly normally JPY 1,000; PPHKMONTH50 gives the first paid month for JPY 500, then JPY 1,000/month auto-renewal unless cancelled. New subscribers only. Eligible users receive the existing 7-day introductory free trial first; Apple determines eligibility.
- Lifetime normally JPY 6,000; PPHKLIFE50 gives JPY 3,000. One-time purchase, no recurring subscription. New and returning paying users are eligible; existing owners do not need to repurchase. Buying lifetime does not automatically cancel an existing monthly subscription.
- Both offers are Japan storefront only. Each new code has a 500-redemption cap, 1,000 total across two independent pools, with no redemption expiration date. This is a configured total cap, not a live remaining-stock count. Codes stop working at the cap or if deactivated. Existing older campaigns were not modified.
- The unified page presents both 50% offers to every visitor, including visits from old A/B links. Apple API readback verified prices, eligibility, active status, limits and null expiration dates. No production redemption was made to test or consume the quota.
