Niseko Guide - Hokkaido Trips (iOS app)
Privacy Policy
Takayuki Hashimoto (Family App Studio, the "Developer") sets out below how the iOS app "Niseko Guide - Hokkaido Trips" (the "App") handles your information. By using the App you agree to this policy.
1. Overview
The App works without an account and never asks for your name, email address, phone number, or other personally identifying details. Your travel data, such as trip plans, bookings, expenses, and photos, is stored only on your device by default. Information is sent to the Developer's servers only when you use the AI features described in section 3.
2. Data stored on your device
- Trip plans (dates, schedule items, places, travel legs, expenses, notes)
- Booking details (flight numbers, accommodation, confirmation numbers, and other details copied by the import feature)
- Trip photos and booking images (copied into the App's storage)
- Display preferences (last opened tab, map region, and so on)
This data is not sent to the Developer's servers. Deleting the App removes it from your device. Whether it is included in device backups (such as iCloud Backup) depends on your iOS settings.
3. Data sent when you use AI features
When you use the features below, the necessary information is sent through the Developer's servers (Google Cloud / Firebase, Tokyo region) to the AI provider DeepSeek (DeepSeek API). Data is sent only when you use the feature, never in the background.
3.1 AI travel assistant (Premium feature)
| Data sent |
|
|---|---|
| Server handling | Message text and trip plan content are not stored on the server and do not appear in logs. Usage counters (identifier and count per day) are deleted automatically after a fixed period. |
3.2 Booking email import
This feature reads confirmation emails you paste or images you select and copies flight numbers, dates, accommodation, and similar details into your trip. Text recognition on images happens on your device; the images themselves are never uploaded. The extracted text and your trip dates are sent to the server, and the AI returns the structured result. The text is not stored on the server or in logs.
3.3 Place lookup from schedule item names
Based on the name of a schedule item (such as a venue) and the planned visit time, the AI looks up opening hours, address, and similar details. The result is stored on the server as a shared cache that is reused for other users who enter the same name. Only the item name and the lookup result are stored; nothing that identifies you is included.
4. Advertising
If you do not subscribe to Premium, the App shows ads through Google AdMob. Through mediation, ads from Zucks and Unity Ads may also appear. To deliver ads, prevent fraud, and measure performance, the ad SDKs may collect the advertising identifier (IDFA, only if you allow tracking), IP address, device and OS information, and app usage data.
If you decline the iOS "Allow Tracking" prompt, the advertising identifier is not used and non-personalized ads are shown. You can change this at any time in iOS Settings → Privacy & Security → Tracking. Premium subscribers see no ads.
5. Analytics
To improve the App we use Google Analytics for Firebase. It collects statistics such as ad load, impression, and tap events, app launches, OS and app versions, device type, and approximate region. This data is not used to identify you personally.
6. Location
With your permission, the App uses your device's location to show your current position on the map. Location data is used only on the device for map display and is not sent to the Developer's servers. You can change the permission at any time in iOS Settings → Privacy & Security → Location Services.
7. Photos
When you pick trip photos or booking images, the App uses the iOS photo picker. Only the photos you choose are passed to the App; the App does not access your whole photo library.
8. Subscription (Premium)
Purchases and payments are processed by Apple. The Developer never receives payment details such as card numbers. When you use the AI travel assistant, the Developer's server verifies the Apple-signed transaction to confirm your subscription is active. You can manage or cancel the subscription in your Apple ID settings.
9. Spot data delivery and external links
Spot listings, photos, and ratings are delivered from the Developer's servers (Firebase Hosting). Connection details such as your IP address are processed temporarily by Google's infrastructure when the data is fetched. When you open external links such as official or booking websites, the linked operator's privacy policy applies. Content you share through the itinerary sharing feature is handled by the app you choose as the destination.
