Studio Spark ยท Reef Guardian
Game & purchase information
Updated 3 October 2026. This page describes the current TestFlight testing version and explains where to find purchase, reward and support information. Paid purchases are not enabled in this testing version. Purchase information below applies when a product is offered through the store.
Who operates Reef Guardian
Reef Guardian is operated by Saewok Park, a sole proprietor trading as Studio Spark in the Republic of Korea. For game, purchase or privacy enquiries, contact s.park.dxbb@gmail.com.
App licence and your rights
On Apple platforms, the Apple Standard End User Licence Agreement applies unless a different licence is provided in the App Store. This page provides service information and does not replace that licence or limit mandatory consumer rights.
Progress and recovery
The current testing version saves progress on your device. It does not provide player-facing Apple or Google account linking or cloud-save recovery. Uninstalling the game, clearing storage or losing the device may lose guest progress. If you need help, contact support before removing app data. This website has no login or checkout.
Pearls and Journey rewards
When available, Pearl packs and Double Journey rewards are purchased inside the app through the relevant store. Check the store confirmation for the product, local price and included benefit before confirming. Pearls are an in-game resource used for game items, including Special Chests.
Double Journey rewards refers to rewards in Journey. It is not an experience-point multiplier. The purchase screen must explain which Journey rewards are covered, the purchase scope and recovery conditions before this product becomes available. This testing version does not offer a paid Journey unlock.
Random chest rewards
Before spending Pearls on a Special Chest, check Chest probabilities for eligible rewards, progress-dependent chances and guarantees. Choose the highest stage you have cleared to see the relevant table. A random chest does not promise a specific item unless the stated guarantee applies. The published table identifies its rules and source snapshot; it must match the game version you are using.
Optional rewarded ads
You choose whether to request a rewarded ad. Availability depends on your connection, privacy choices, the ad provider and available ads. A loading attempt or a failed ad is not a completed rewarded ad. TestFlight testing uses test ads and does not create advertising revenue. If an ad or reward fails, contact support with the game version, approximate time and reward location.
Purchase problems and refunds
If a purchase is charged but its item does not arrive, avoid buying it again while the first transaction is investigated. Email the product name, purchase date and store transaction reference. Do not send passwords, sign-in codes, card numbers or bank statements.
For Apple purchases, request a refund through Apple Report a Problem. See Apple's refund guidance. Eligibility depends on the store process and applicable law; contacting us does not remove your statutory rights. This website does not process payments or refunds.
Support, privacy and data requests
See Support, the Privacy Policy and Account & data requests. Device-only saves cannot be remotely erased from a game backend by sending an email. We can explain storage controls and handle records we actually hold.
Changes
We update this information when available services or purchase terms change. Material changes will receive any additional notice required by applicable law.
