STK SMASH
Privacy Policy
Last updated: 6 November 2026
This policy explains how EX STK processes information when you use STK Smash. Contact: contact@exstk.com.
Accounts and saved progress
You can play without creating an account. Optional Sign in with Apple or Google supplies an account identifier and available profile information, such as your email address and name. We use these to authenticate you and save or restore your progress through Supabase. Your provider password is not sent to EX STK. Saved records may include completed levels, currency, inventory, rewards, purchase entitlements, preferences, your chosen player name and avatar, and your selected country.
Game Center and rankings
On supported Apple devices, the game can connect to your existing Game Center account and submit completed-level progress to Apple leaderboards. Apple processes your Game Center identity and score under its own privacy policy and settings. Your chosen in-game name and avatar remain your profile choices; using your Game Center picture is optional. Public rankings may display player names and scores. Country selection does not use GPS.
Advertising and your choices
STK Smash uses Google AdMob mediation, including Unity Ads and Liftoff Monetize (Vungle). Depending on consent, device settings and SDK operation, these services may process IP addresses and approximate location, device or advertising identifiers, purchase or usage signals, ad impressions and interactions, and technical diagnostics. Purposes include delivering and measuring ads, analytics, fraud prevention and service reliability. Where required, a consent message lets you make advertising choices. Available choices can be revisited through Privacy options in the game settings. On Apple devices, permission for cross-app tracking is controlled by App Tracking Transparency and can be changed in device Settings > Privacy & Security > Tracking. Declining tracking does not prevent core gameplay. Rewarded ads are optional; ad availability is not guaranteed.
Purchases
Apple handles payments for iOS in-app purchases. We process product identifiers, transaction references and entitlement status to grant purchases, prevent duplicate rewards and restore eligible purchases. EX STK does not receive your full payment card details. Consumable currency and time-limited packs are not re-granted by Restore Purchases. Store purchase records remain subject to Apple’s policies.
Notifications
Optional event and character reminders are scheduled locally on your device. Notification preferences may be saved with your game account. The current reminder feature does not register a remote push notification token. You can disable notifications in the game or in your device notification settings.
How information is used and shared
Account and gameplay information is used to operate requested game features, maintain progress, manage entitlements, provide rankings and support, and protect the service. Supabase provides account and backend hosting; Apple and Google provide their respective sign-in services; Apple provides Game Center and iOS purchases. Advertising partners process advertising information under their own policies. Service processing may take place outside your country, subject to applicable protections.
Retention and deletion
We retain account-linked progress while needed to provide your account and requested features. You can request account deletion inside Settings > Save progress / Account > Delete account, or email contact@exstk.com with “STK Smash Account Deletion” and your account identifier or sign-in email. Identity verification may be required. Deletion removes the game account and associated data through the account service; limited records may remain where necessary for legal obligations, security, fraud prevention or disputes. Device-local progress and third-party records are separate. Deleting your game account does not delete your Apple or Google account or automatically request a refund. Never send passwords or verification codes.
Your rights and contact
Depending on applicable law, you may request access, correction, export, deletion, restriction or objection to processing, and withdraw consent where processing relies on consent. Contact EX STK at contact@exstk.com. You may also contact your local data protection authority. We will update this page when our data practices change.
