Privacy
Policy.

Double Thread is an offline-first puzzle arcade game for iPhone. It does not require an account, contain advertising or cross-app tracking, or send analytics to the developer.

Effective date · 2026.08.09
§ 01

Summary

Double Thread is provided by Denis Ivanov ("we", "us", or "the developer"). This policy explains how the iOS app handles information.

Double Thread does not require an account. The production app does not contain advertising, cross-app tracking, an analytics upload service, or third-party tracking SDKs. We do not sell personal information.

§ 02

Information stored on your device

The app stores gameplay progress, settings, local scores, active-run data, replays, Album artwork, and a cache of the last verified Full Game entitlement inside the app's local container. This information is used only to provide the game's features and is not uploaded to a server operated by the developer.

You can use Settings → Reset Progress to remove campaign progress and Album items while keeping a verified purchase entitlement. Removing the app normally removes its local data. Restoring a device backup may restore data according to Apple's backup behavior.

§ 03

Apple services

Double Thread can use the following Apple services:

  • In-App Purchase / StoreKit. Apple processes the purchase and payment. The app receives product information and cryptographically verified transaction and entitlement status. The developer does not receive your payment-card details.
  • Game Center. Game Center is optional. If you choose to authenticate, the app can submit eligible scores and achievement progress to Apple. Game Center identity and records are managed under your Apple Account and Apple's terms. Reset Progress in Double Thread does not erase Apple's Game Center records.
  • System share sheet. Sharing begins only after your explicit action. You choose the destination and recipients in Apple's system interface. The app does not receive the identities of recipients.

Apple may process information independently under Apple's Privacy Policy ↗.

§ 04

Diagnostics and TestFlight

The App Store production configuration uses no remote telemetry endpoint. Development and TestFlight diagnostics may be kept locally in a bounded log and are exported only when a tester explicitly chooses to share them. Please review an export before sending it to support.

§ 05

Network access

Core gameplay, unlocked campaign content, settings, local Daily content, Album, and local sharing are designed to work offline. Network access is used only for Apple-provided services such as loading or restoring an In-App Purchase and optional Game Center functionality.

§ 06

Children

The app is not specifically directed to children and does not knowingly collect personal information from children through a developer-operated service.

§ 07

Retention and deletion

Local game data remains on the device until you reset it, remove the app, or the operating system removes it. Purchase history and Game Center records are held by Apple and must be managed through the applicable Apple services.

§ 08

Changes to this policy

We may update this policy when the app or legal requirements change. The current version and effective date will be published on the Double Thread privacy page.

§ 09
