Privacy Policy

1. Information we collect

No account is required. We do not receive your favorites, folding progress, finished folds, notes or settings through the App. Advertising data is collected and shared by Google Mobile Ads as described in section 7; support emails are handled as described in section 11.

The App includes the Google Firebase SDKs (Analytics, Crashlytics and Remote Config) to collect usage statistics and crash reports and to check whether an update is required, as described in section 7. It does not track your location with GPS. It also includes the Google Mobile Ads SDK (Google AdMob) to show ads; the ad data Google processes is described in section 7.

2. Information stored only on your device

The following information, created as you use the App, is stored only in the App’s private storage on your device. We cannot access it.

• Favorites - the projects you saved with the heart
• Progress - the step you reached in each project, the playback position of the folding animation and the project you folded last
• Finished folds - the project, the date and time, the paper color you chose and any note you wrote (your day streak and learning path progress are calculated from these records)
• Settings - app language, paper color and gentle vibrations

All folding guides and diagrams are built into the App, so they are shown on your device without an internet connection. The App has no separate lock or encryption; the information is protected by your device’s own security, such as its screen lock. We recommend not writing anything in notes that you would not want others to see. Deleting the App removes this information from your device, although copies in device backups may remain (see section 6).

3. Text backup and restore

Tapping "Copy backup" in Settings copies a text containing your favorites, progress, finished folds, notes and settings to your device’s clipboard. This text is never sent to us, and you decide where to paste and keep it. Depending on your device settings, other apps may be able to read the clipboard, so we recommend copying something else after you have saved your backup.

When you paste a backup into "Restore a backup", the App checks it on your device and then replaces the studio currently on the device with its contents.

4. Folding guides and in-app content

Projects, folding steps, learning paths and creative invitations are all included in the App. The App does not access your camera or photo library.

Tapping "Check latest version" in Settings opens the App Store or Google Play on your device. The open-source licenses screen only displays license text included in the App.

5. Device permissions

The App does not request access to location, contacts, photos, camera, microphone, calendar or notifications. Android declares network and advertising ID permissions without a runtime permission prompt. The ad SDK may process the advertising ID. On Android, Firebase Analytics may also read the advertising ID where your OS and settings allow.

The App uses light vibrations as you move between folding steps. You can turn them off with "Gentle vibrations" in Settings.

6. Device backups

Depending on your device settings, App data may be included in device backups such as iCloud backup on iPhone or Google backup on Android. These backups are handled not by us but by Apple (https://www.apple.com/legal/privacy/) or Google (https://policies.google.com/privacy) under their own policies.

7. Ads, third parties and app stores

The App shows a banner ad through Google AdMob at the bottom of its main screens (Today, Discover, Learn and My studio). No ads appear on the folding guide screens. This app is intended for adults aged 18 and over and is not intended for anyone under 18. The main screens display Google AdMob banners. Advertising information, including the advertising ID, may be used for personalized ads, subject to consent where required. Without consent, non-personalized or limited ads, or no ads, may be shown. Ad content is restricted to the general audience rating (G); adult content is not allowed. To load ads, the Google Mobile Ads SDK connects to the internet, and Google may collect and process your IP address (including approximate location), device information, ad interactions and diagnostic information to deliver ads, measure performance and prevent fraud. This data is encrypted in transit.

In regions where consent is required, the App shows Google’s consent form, and you can change your choices at any time in "Ad privacy choices", which then appears in Settings.

Your favorites, progress, finished folds, notes and settings are not passed to the ad SDK. Google processes ad data under its own policies, and it may be processed on servers outside your country (https://policies.google.com/privacy) (https://policies.google.com/technologies/ads).

Google Mobile Ads may collect and share IP addresses (approximate location), device identifiers including the advertising ID, app interactions and diagnostics including crash and performance data with Google and its advertising partners for advertising, analytics and fraud prevention. Your folding records and notes are not passed to the ad SDK.

Google Firebase: store (release) versions of the App for Android and iOS include the following Google Firebase SDKs provided by Google LLC: firebase_core, firebase_analytics, firebase_crashlytics and firebase_remote_config. Development builds do not send this data, and if Firebase cannot start, the App keeps working without sending anything.

Firebase Analytics collects automatically recorded usage events (such as app opens, first opens, screen views and session length), the app version, device model, OS version, language and country settings, an app-instance ID and an approximate location derived from your IP address (GPS is not used). On Android, it may also read the advertising ID where your OS and settings allow. We use this to understand how the App is used and to improve it. Event-level data is kept for 2 months; aggregated reports may be kept longer.

Firebase Crashlytics collects, when the App crashes or runs into an error, the stack trace, app version, device model, OS version, free memory and storage, screen orientation, a Crashlytics installation UUID and the time of the crash. We use this only to find and fix bugs, and crash reports are kept for about 90 days.

Firebase Remote Config: when the App starts or returns to the foreground, it fetches a small configuration to decide whether to show a screen asking you to update. This request sends the Firebase installation ID, the app ID and version, the platform and your language and country settings.

Nothing you write or create in the App is sent to Firebase. Data is sent over encrypted connections (TLS), and Google processes it as our service provider. We see only aggregated statistics and crash reports that do not identify you by name or email address. The App has no setting to turn this off; deleting the App stops further collection. Learn how Google handles Firebase data (https://firebase.google.com/support/privacy).

In-app purchase (Android only): the Android version of the App offers one optional, one-time "Remove ads" purchase through Google Play that turns off the ads. There are no subscriptions, and the iPhone and iPad version has no in-app purchases. Payment is handled entirely by Google Play Billing, and we never receive your card or payment details. The App stores only the purchase status on your device and re-checks it against Google Play's purchase records when it starts, so refunds are reflected. Refunds and cancellations follow Google Play's policies. On Android, Firebase Analytics may record purchase events (product ID, price and currency).

The App is distributed through the Apple App Store and Google Play. Downloads, payments and reviews are handled by each store under its own privacy policy. The stores may provide us with statistics such as download counts and, depending on your device settings, crash reports that do not contain your studio records.

8. Ages 18 and over

This app is intended for adults aged 18 and over and is not intended for anyone under 18.

9. Retention and deletion

Information stays on your device until you delete it. To delete a single finished fold, open its menu in My studio and tap Delete. To delete your records at once, tap Settings > Clear studio data. This removes your favorites, progress and finished folds, while your language, paper color and vibration settings stay as they are. This cannot be undone.

Deleting the App removes all of its data, including settings, from your device. Text backups you have kept elsewhere and copies in device backups must be deleted from those places separately.

Resetting your records or deleting the App does not delete ad data Google has already processed. Manage it with Google’s privacy tools. We cannot delete data held by Google.

Usage statistics and crash reports already sent to Google Firebase are not deleted when you reset your records or delete the App; they are deleted after their retention periods (2 months for event-level Analytics data and about 90 days for crash reports).

10. Your rights and how to contact us

You can view, change or delete local folding records in the App. For advertising data, use Google's privacy controls and the ad consent options described above. Contact us below about this policy or access to and deletion of support emails.

Firebase Analytics and Crashlytics cannot be turned off in the App; deleting the App stops further collection. For data processed by Google, see (https://firebase.google.com/support/privacy).

11. Support emails

When you email us, we receive your email address, your message and anything you attach. We use this information only to reply and resolve your issue, and keep it only as long as needed to handle your inquiry and comply with applicable law. Please send backup text only when it is truly needed to solve a problem, and do not send payment card details or passwords.

12. Changes to this policy

We may update this policy when laws or App features change, and we will post the updated version on this page with a new effective date.
