Core Containment- Privacy Policy
Last updated: September 22, 2026
Core Containment does not collect, store or share any personal information.
No data collection. The game does not use analytics, advertising, tracking or crash-reporting services, and it does not send any information to the developer.
On your device only. Your progress, scores, callsign and settings are saved only on your device, in the app's own storage. Deleting the app deletes them. Nothing is uploaded to the developer or to any third party.
Game Center. If you are signed in to Game Center, your achievements and leaderboard scores are handled by Apple under Apple's privacy policy. The game works fully without Game Center.
Purchases. The optional in-app purchase is processed entirely by Apple. The developer never receives your payment details.
Photos. If you choose to save a Daily Deck result card, the game writes that one image to your photo library. It never reads your photos.
Children. Because no information is collected, the game is suitable for players of all ages.

Core Containment- Support and FAQ

HOW TO PLAY
What am I supposed to do?
Drag anywhere on the deck to raise a containment field. It grows in both directions until it reaches a wall and seals. If a core touches it while it's still growing, it shatters and you lose a point of integrity. Once a wall seals, any side with no core in it becomes claimed ground. Claim the target percentage shown at the top and the deck is secured.
How do I choose which way the field grows?
The direction of your drag picks the axis. Drag sideways for a horizontal field, up or down for a vertical one.
Can I cancel a field?
Yes. Before it fires, tap with a second finger, or slide your finger off the deck and let go.
What are the chips on the deck?
Supplies. Tap one to collect it. Some act at once (points, integrity); others go into the tray under the deck to use when you want. From deck 10 each deck also issues a kit straight to the tray. The in-game Briefing on the main menu has a full page on each one.
Who is the thing at the top of the deck?
God-Emperor Deblon. He appears from deck 5. Magenta on the deck means his beam is coming: it breaks growing fields and scorches claimed ground. Sealing the ground directly under him cuts his grip.
The game is getting really hard.
It's meant to. A few things help: seal small pockets near the edges before going for the middle, wait for a gap before you drag, and don't ignore the tray. Ground you've held for ten seconds hardens and resists Deblon. Shielded fields can't be shattered and won't split corrupted cores. If a deck is going badly, pause and choose RESTART DECK; it keeps your score from the decks before it.
What is the Daily Deck?
One seeded deck per day, the same for everyone in the world, changing at midnight UTC. Your best score and fastest clear go to their own Game Center leaderboards. Sundays run a challenge rule. Clearing it daily builds a streak.
Does it end at deck 100?
No. Deck 100 is the bottom of New Orange City, and clearing it opens the second descent: the stair keeps going.
THE PURCHASE
What's free and what's paid?
Decks 1–20 and the Daily Deck are free, forever, with no ads. One optional purchase, Deep Clearance, opens deck 21 and everything below it, plus four city themes and three core styles. Nothing in it changes difficulty, scoring or leaderboards.
I bought it but the game still stops at deck 20.
Open REQUISITION from the main menu and tap RESTORE PURCHASES. That reads your purchase from your Apple Account and unlocks it on this phone. You need to be signed in to the same Apple Account you bought it with, and online.
I got a new phone. Do I buy it again?
No. Install the game, open REQUISITION and tap RESTORE PURCHASES.
Where do I change themes?
SETTINGS, then APPEARANCE, on the main menu. Themes apply from the next deck you start.
Refunds
Purchases are handled by Apple. Request a refund at reportaproblem.apple.com; the developer can't issue refunds directly.
SAVES AND GAME CENTER
Is my progress backed up?
Your progress is saved on the phone and included in your normal iPhone backup. It isn't synced between devices. Deleting the app deletes your progress; the purchase can always be restored.
Game Center isn't signing in.
The game asks once at launch. If you dismissed it, sign in from the iPhone Settings app under Game Center, then relaunch. Achievements you've already earned are reported the next time you clear a deck while signed in.
Can I reset everything?
SETTINGS, then RESET ALL PROGRESS, tapped twice. It wipes scores, progress, daily history and settings on this phone. It does not remove your purchase.
TROUBLESHOOTING
My swipe pulls down Notification Center or switches apps.
The game asks iOS to give it the first swipe from each screen edge, so leaving the game takes two swipes. If the first swipe still leaves, check that Guided Access isn't on.
It's warm or the battery drops fast.
Turn on BATTERY SAVER under SETTINGS, DISPLAY. It runs the game at 30 frames a second and turns off the glow.
Sound is off.
Check the phone's silent switch and volume first, then SETTINGS, SOUND in the game. Music and effects have separate switches.
