YŌKAI FIELD GUIDE PRIVACY
Prepared September 23, 2026. This policy describes the current unreleased development preview. It will be reviewed against the actual release before App Store publication.
Information stored on your device
The app stores bookmarked entry identifiers, your selected text size, and the last opened page of each story locally. Searches remain in memory and are not sent to us. There is no sign-in or app-managed cloud sync. Your device or browser backup settings may include local app data.
Content and third-party services
Entry text, historical stories, research notes and illustrations are bundled with the native app for offline reading. The current preview integrates no advertising SDK, analytics, crash-reporting service, remote content downloads, over-the-air update service or runtime AI service. AI-assisted artwork is prepared during production; using the app does not send prompts or reader data to an AI provider.
Book and film recommendations
The app lists selected books and films as optional companions. Shopping links are inactive in this preview: it does not connect to Amazon, load Amazon images or use an Amazon SDK. Source credits are readable inside the app and do not open external research websites.
Amazon.com affiliate links are planned for a later revision, subject to account setup and mobile-app approval. If enabled, marked links will open outside the app. Amazon will receive the affiliate tag and normal connection information, such as your IP address and browser or device details, under its own privacy policy. We will not attach your searches, bookmarks or reading position. We will review this policy again before activating those links.
Purchases
No purchases, subscriptions or payment SDKs are enabled in version 0.1.0. A permanent unlock is being considered for a future release. If purchases are added, this policy will be updated to describe the actual implementation.
Development and browser previews
A development preview loads code from a development server and may use Expo development tooling. The browser preview stores preferences in that browser's local storage. These previews are not distributed App Store builds, and their networking is different from a standalone native app.
Control and deletion
Tap a saved entry's bookmark button to remove it. Removing the native app's local data or clearing this preview's browser site data removes the saved preferences. Device or browser backups are managed separately through your platform.
Support correspondence
If you email apps@theylivehere.com, we receive your email address and whatever information you choose to include so we can respond. Email is handled by email service providers; it is separate from the app's local reading data. Contact us at that address with questions or requests about your support correspondence.
