You do not need a MOKUSEI account to play. Progress and ghost recordings are stored on your device. Certain online services, described below, process data required for their operation.
1. Who is responsible?
Sekai Running is published under the studio name MOKUSEI INC.. The responsible publisher for this policy is Sadrach Lucas Gabriel. For privacy questions or to exercise your rights, contact mokuseiinc@icloud.com.
2. Progress and local data
The game stores completed levels, coins, owned equipment, collected crystals, game preferences, language and privacy choices, and the verified date of the last daily reward on your device. Ghost recordings contain positions, actions and run results. They are not a public leaderboard.
The game code does not send this save file to a MOKUSEI progression server. No MOKUSEI account or cloud progress sync is provided. Local data remains until it is erased; Apple may separately manage device backup and restoration.
3. Services used by certain features
Daily reward. The game contacts TimeAPI over HTTPS to verify the UTC day. This request does not include your save file, name or coin balance. Like any Internet service, the recipient receives your IP address and technical connection information. A random identifier for that request prevents an outdated response.
Game Center. When the device account is available, Apple provides its connection status and display name to the game. The game does not use this feature to sync progress. Apple manages the account and Game Center data.
In-app purchases, when available. Apple handles payment and supplies the information required to confirm a purchase. The game stores the transaction identifier, product and delivered content locally to prevent duplicate delivery. MOKUSEI does not receive your card number. Delivered consumables cannot be recovered through Restore Purchases after local save data is erased.
Unity IAP service data. The purchasing SDK also sends Unity events about purchase attempts, payments, failures and delivery. These may include the product, amount, currency, transaction identifiers, Apple receipts and signed transaction data, available installation or session identifiers, the Apple device vendor identifier (IDFV), game and system versions, and diagnostic information. This data supports purchase processing and reporting, security and service diagnostics. A local wallet therefore does not mean that all purchase data stays on your device.
Purchase SDK transmissions are separate from your advertising choice: declining ads does not disable them. For IAP data processed on our behalf, contact us so we can forward your request to Unity. For processing for which Unity is responsible, its procedures are described in its Privacy Policy and Unity IAP privacy notice.
4. Advertising and privacy choices
The game integrates Unity LevelPlay with Unity Ads and ironSource. These services may process device and network information, identifiers according to the permissions granted, and ad impressions and interactions to deliver ads, measure their operation and prevent fraud.
The game lets you choose contextual ads, personalized ads, or decline ads. Advertising initialization depends on this choice. Personalization also requires Apple tracking authorization on iOS; denying it does not stop you from playing. Your choice, its version and its date are stored on your device.
You can change your choice in Settings → Privacy. Tracking permissions can also be managed in Apple’s settings. Unity and its companies describe their processing in the Game Player and App User Privacy Policy. Contextual ads can still require technical data; they do not mean that no data is processed.
5. This website and your messages
This static website is hosted by Cloudflare. We do not embed ads, tracking pixels, audience analytics or forms that automatically send your information. Images and styles are served from this site. The host processes connection data, including IP addresses and technical logs, to deliver and secure these pages. See the Cloudflare Privacy Policy.
The contact link opens your email application. We receive only the message you choose to send, your reply address and any attachments. We use them to handle your request. Please do not include passwords or payment details.
6. Purposes, recipients and retention
Data is used to operate requested features, manage your preferences, secure services and provide support. Where consent is required, including advertising personalization and tracking, you are asked to make the applicable choices. Depending on the processing and applicable law, other bases include providing the requested service, legitimate interests in security and support, or a legal obligation.
Recipients are the providers described on this page and the people handling your support request. Support messages are retained as needed to respond and resolve the issue, then deleted or anonymized, subject to legal retention obligations. Providers apply the retention periods and safeguards explained in their own policies.
Some providers may process data in other countries. Their policies describe the applicable transfer safeguards. We do not sell your support messages or local save data.
7. Your choices and rights
Contact mokuseiinc@icloud.com to request access, correction, deletion, restriction, objection or portability for data we process, where applicable under your local law. You can withdraw consent without affecting processing already carried out on that basis. You may also contact your data protection authority, including the CNIL in France.
Because progression and ghost files are local, we cannot remotely view or delete their copy on your device. Deleting the app and its data normally removes that copy; any Apple backups must be managed separately. This may cause loss of coins and progress. For data held directly by Apple or Unity, their privacy procedures are also available.
8. Intended audience and updates
Sekai Running is designed for teenagers and adults; it is not designed primarily for children under 13. If you believe you have sent us information about a child, contact us so that we can review the request.
We will update this page if features or service providers change. The revision date is shown above. Consent choices will be renewed where the changes require it.
