1. Information we process

The paid Google Play and App Store editions (version 1.1.0 and later) have no sign-up or sign-in and send no information to our server or to any advertising or analytics service. Game progress stays on your device. Only Apps-in-Toss sends an HMAC of your anonymous Toss key, daily completed-run counts, reward balance, ledger and payout keys to our AWS server in Seoul. We do not collect names or contact details.

2. Information stored on your device

Your game in progress, best score, total deliveries, settings, and tutorial status are stored in the app's storage on your device. On Apps-in-Toss, records that have not been sent yet and exchange recovery details are also kept there, while the stamp balance and ledger are kept on our server and restored with the same anonymous key. In the paid Google Play and App Store editions (version 1.1.0 and later) these records are not backed up to any server, so they cannot be recovered after you delete the app or change devices. Toss reward records are kept until you request deletion by contacting support@sleite.com; pending exchanges must be reconciled first.

3. Toss promotion

Game progress stays on your device. Only Apps-in-Toss sends an HMAC of your anonymous Toss key, daily completed-run counts, reward balance, ledger and payout keys to our AWS server in Seoul. We do not collect names or contact details.

Toss reward records are kept until you request deletion by contacting support@sleite.com; pending exchanges must be reconciled first. Local game progress and platform purchases are separate.

4. Platform notes

App StorePostmark Lane runs as an iOS app. Information Apple processes while distributing, updating, backing up, and securing the app is governed by Apple's own policies.
Google PlayPostmark Lane runs as an Android app. Information Google processes while distributing, updating, backing up, and securing the app is governed by Google's own policies.

5. Advertising

The paid Google Play and App Store editions (version 1.1.0 and later) show no ads and do not include an advertising SDK. Earlier free editions (the free Google Play app and App Store versions before 1.1.0) use rewarded and interstitial ads from Google Mobile Ads. To serve ads, control frequency, measure performance, diagnose errors, and prevent abuse, Google and its advertising partners may process approximate location inferred from an IP address, device and app environment information, device identifiers, ad request, impression and interaction data, and crash, diagnostic and performance information. Device identifiers may be used for tracking for third-party advertising and analytics. Where required, Google's privacy options screen is available in those editions. Their app code does not request App Tracking Transparency permission or directly read the IDFA, but other device identifiers may be processed according to the SDK and your consent choices. Apps-in-Toss: Viva Republica (Toss Ads).

6. In-app purchases

Unlimited Pass is sold only on Apps-in-Toss and in earlier free editions, through that platform's payment system. Your payment details and purchase history are handled under that platform's policies; the app only checks whether the purchase exists so it can apply or restore it. The paid Google Play and App Store editions are bought from the store and have no in-app purchases; Apple or Google handles that purchase and the app receives none of its details.

7. How long we keep information

Apps-in-TossToss reward records are kept until you request deletion by contacting support@sleite.com; pending exchanges must be reconciled first. Local game progress and platform purchases are separate.

We are a business registered in the Republic of Korea, so Korean law sets these retention periods. Information that a law requires us to keep is stored separately for that period and then deleted beyond recovery.

8. Sharing and processors

We share personal information with a third party only with your consent or where the law provides a basis. If an investigative authority makes a lawful request under Korean law, we may provide information within the scope of that request.

9. Your rights and deletion

You can ask to see, correct, or delete your Apps-in-Toss promotion records at support@sleite.com. Pending exchanges are handled after the payout result is confirmed. Deleted stamps cannot be restored; game records on your device and platform purchases stay separate.

The Google Play and App Store apps have no account and store nothing on our server, so there is no server account to delete; deleting the app removes its records.

10. Security measures

Traffic to our server is protected with HTTPS. Database credentials and signing keys are kept only in the server's secret store, never in source code. Access to information is limited to the minimum needed to operate the service.

11. Where your information is processed

The advertising and platform providers named in this policy operate in multiple countries. When ads are served, the ad-related information described above is processed by Google LLC in the United States and in other countries where Google operates. Information processed by Apple or Google for app distribution and payment is handled under their own policies.

Our own server, which stores the records described above, is hosted by Amazon Web Services in Seoul, Republic of Korea.

Where the law of your country requires notice, consent, or safeguards for this kind of cross-border processing, we follow it.

12. For users in the EEA, the UK, and Switzerland

Where the GDPR or equivalent law applies, we process personal information on these legal bases: your consent (for ad-related storage or identifiers where consent is required — Google's privacy options screen collects it); performance of a contract (providing the Service you request); our legitimate interests (keeping the Service secure, preventing fraud and abuse, and keeping it stable); and compliance with a legal obligation.

In addition to the rights above, you can ask us to restrict processing, object to processing based on legitimate interests, and receive a copy of information you provided in a portable format. Where processing is based on consent, you can withdraw it at any time without affecting the lawfulness of processing before the withdrawal.

You can also lodge a complaint with the data protection supervisory authority of your country.

13. For users in Japan

Where the Act on the Protection of Personal Information (APPI) applies, we use personal information within the purposes stated in this policy. You can ask us to disclose, correct, stop using, or delete the personal information we hold about you through the contact below. Where personal information is provided to a third party or handled outside Japan, we follow the notice, consent, and safeguard requirements of the APPI.

14. Contact

Send questions about how we handle personal information, and any request to exercise your rights, to support@sleite.com.

15. Changes to this policy

If what we process changes, we revise this policy and show its effective date before releasing that update. We give notice from 7 days before the date it applies, and from 30 days before for an important change that is unfavourable to you.
