What we collect
Everyday lessons and practice do not require an account. If you join the optional Instructor Advisory Circle, we receive your name, city/state, teaching background, email, application identifier and submitted reviews. We use them to verify your application, maintain review credits and provide instructor benefits. Your email and qualification evidence are not public. Your name, city and verified title appear publicly only with your permission and approved contributions. Guest passes store a hashed device access key and expiry. Contact support to request correction, removal or withdrawal of public credit. We retain application and review records while operating your membership and maintaining the associated editorial history.
What stays on your device
Your settings (tile size, contrast, speed), your lesson progress, your practice-game history and any hands you enter from your own card are saved only on your iPhone or iPad, in the app’s own local storage (the system settings store, called UserDefaults, plus one small file in the app’s folder for your hands). Nothing syncs between devices through us or through iCloud. This data is included in your normal device backup if you have iCloud Backup or a computer backup turned on, which is handled by Apple under Apple’s terms. We never see it. Deleting the app deletes it.
Purchases
The one-time purchase that unlocks Tilebird Coaching is processed by Apple through the App Store. Apple handles payment, receipts, refunds and restoring the purchase on your other devices (Settings → Restore Purchases in the app). We do not receive your name, address or payment details.
Offline, with no third-party advertising or analytics
Built-in lessons, practice and rules remain available offline. The app checks for updated content bundles. Optional instructor applications and saved review drafts sync when the app is open and a connection is available. Requests reach our server, which necessarily receives connection information such as an IP address. There are no advertising, third-party analytics or tracking SDKs. Apple handles purchases and any diagnostic sharing you enable in your device settings.
Teacher links
A teacher may send you a link such as tilebird.club/go/lesson/…?by=Name. The name in the link is shown to you inside the app and is not sent anywhere. Opening a link on a device without the app loads a page on this website, which is covered by the “This website” section below.
This website
This website uses no analytics, no advertising and no tracking cookies. Our web server keeps standard access logs (IP address, requested page, browser type) for security and troubleshooting, deleted on a rolling basis. If you email us, we use what you send us to respond. The instructor form is covered above. This browser stores a private application access key so you can check status; protect it and do not share it publicly.
Children
The learning app has no chat or public community. Instructor applications are intended for adult teachers and experienced adult players. Reviewer cards are shared only when the user chooses to share them.
Changes
If this policy changes, the new version will appear on this page with a new date. Please check this page when using optional online features.
