This application "WindWisp" (the "App") considers the protection of users' personal information to be of the utmost importance, and has established the following Privacy Policy.
The App is an entertainment app in which you launch a virtual balloon, guided by wind data (direction and speed), to meet spirits around the world. The balloon's position is always managed as a virtual coordinate starting from the summit of Mt. Fuji, or from wherever you last met a spirit. The App never collects your actual real-world location (GPS).
2. 取得する情報および利用目的2. Information We Collect and How It's Used
Nickname, avatar (emoji), age range, hobby tags, and bio: Profile information you optionally set. It's shown alongside your balloon on other users' maps, and to anyone you meet through the Correspondence feature (described below). None of this is linked to identifying information such as your real name or email address.
Anonymous ID (Firebase Anonymous Authentication): Automatically generated the first time you open the app, so your balloon can be distinguished from other users' balloons. It is never linked to your name, email address, or other personal information.
Virtual balloon location: The latitude and longitude of your virtual balloon, calculated from wind data. It does not reflect your actual location. This is stored in a Firebase (Google LLC) database so your balloon can be shown on other users' maps.
Letters sent and received through Correspondence: Once two users who have "met" (by satisfying distance and flight-time conditions) both agree to correspond, the actual messages they exchange are delivered to the other user's device via the App's database (Firebase). The developer does not automatically read or make use of this content.
In-game progress (balloon state, Spirit Collection progress, item counts, Memory Match event records, etc.): Generally stored only on your device. Only your Spirit Collection count (used to show your level) is also stored in the Firebase database, for ranking and map display purposes.
Purchase information: Records of in-app purchases (consumable items, non-consumable items, subscriptions) and their usage. All payment processing is handled through Apple Inc.'s systems; the developer never directly obtains your credit card information.
3. データの保存と外部送信について3. Data Storage and External Transmission
Game progress (balloon flight data, Spirit Collection, items, etc.) is generally stored only on your device.
To share your position with, and enable encounters with, other users, your nickname, avatar, virtual balloon position, appearance (image name), and Spirit Collection count (for level display) are stored in a Firebase (Google LLC) database and visible to all other users.
If two users who selected "Start Corresponding" actually begin corresponding, the letter text they exchange is also delivered to the other user's device via the Firebase database. This content is not normally viewed by anyone other than the sender and recipient, including the developer.
Open-Meteo (a weather data provider) may be used to obtain wind data (direction and speed). Only your virtual balloon's latitude and longitude are sent for this purpose; no personally identifying information is included.
While your balloon is flying, the App sends one local notification per day at a time you choose, and additional local notifications for the Memory Match event (four times a day). These use Apple's standard notification system, and the notification content itself does not pass through an external server.
The App offers in-app purchases through the App Store (consumable items, non-consumable appearances/plans, and auto-renewing subscriptions).
All payment and purchase-record management is handled securely through Apple Inc.'s systems. The developer never directly obtains or retains your credit card information or payment details.
Auto-renewing subscriptions (such as speed boosts) renew automatically unless cancelled at least 24 hours before the end of the current period. To cancel, go to iOS Settings → [Your Name] → Subscriptions.
Firebase (Google LLC): Used for anonymous authentication, sharing balloon positions with other users, the Correspondence feature (sending/receiving letters), and ranking aggregation. Firebase Privacy Policy
Open-Meteo: May be used to obtain wind data (direction and speed). No personal information is sent.
The App includes a nickname feature that displays your name to other users, and a Correspondence feature that lets you exchange actual messages with other users. If a minor uses the App, we ask that this be done with a parent or guardian's understanding. Please avoid using your real name or other identifying information in your nickname, bio, or letters.
The App may update this Privacy Policy from time to time to reflect changes in law or app updates. Significant changes will be announced through the app's update notes.
For questions about how the App handles personal information, please contact us at the email address below, or through the App Store's support channel.
These Terms of Service (the "Terms") set out the conditions for using "WindWisp" (the "App"). Please read these Terms carefully before using the App. By using the App, you are deemed to have agreed to these Terms.
The App is an entertainment service in which you launch a virtual balloon guided by wind data and meet the "wind spirit" of wherever it arrives. You can also meet other users who satisfy certain conditions and enjoy Correspondence (exchanging messages) with them. While your balloon's position is calculated from wind data, this is purely a game mechanic and does not guarantee actual weather conditions or mail delivery.
2. 第三者サービスへの依存について2. Reliance on Third-Party Services
In the App, your nickname, avatar, virtual balloon position, appearance, and Spirit Collection count (level) are shared and visible to all other users. Through the Correspondence feature, you may also exchange letters with users you've actually met. By setting up a profile and using the Correspondence feature, you agree that this information will be made public and shared. Please do not include your real name or other identifying information in your nickname, bio, or letters.
4. アプリ内課金・サブスクリプションについて4. In-App Purchases and Subscriptions
The developer may update these Terms as needed. Significant changes will be announced through the app's update notes. Continued use of the App after such changes constitutes agreement to the revised Terms.
These Terms are governed by and interpreted in accordance with the laws of Japan. Any disputes arising in connection with the App shall be subject to the exclusive jurisdiction of the court having jurisdiction over the developer's location, as the court of first instance.
