Privacy Policy
Last updated: September 30, 2026
appishiwata (“we”) provides this Privacy Policy to explain how information is handled in the iOS app “Baby Age Stamp” (the “App”).
1. Information We Handle
The App may handle the following information:
- Photos and videos you select from your photo library (processed and saved on your device)
- Baby birth date and time you register (stored on your device)
- In-app settings and display state stored on your device
- Device and advertising identifiers that advertising networks may collect in connection with ads (described below)
Selected media, stamped results, and baby information are processed and stored on your device. We do not send them to our own servers.
2. Purpose of Use
- Providing postnatal age stamps, preview, and saving to Photos
- Displaying ads (such as banner and native ads)
- Fixing issues and improving app quality
3. Advertising
The App may use advertising services such as Google AdMob to display banner ads and native ads.
In connection with ad delivery, advertising networks may collect and use information such as:
- Advertising identifiers (for example, IDFA, when permitted by the user)
- Device information (model, OS version, etc.)
- Ad impression and click information
- Approximate location information (for example, inferred from IP address)
Such processing is governed by each advertising network’s policies.
Google’s advertising information:

4. Tracking (ATT)
On iOS, using an advertising identifier for tracking across other companies’ apps and websites requires user permission under App Tracking Transparency (ATT).
The App may request this permission to help show more relevant ads. You can use the App’s core features without granting permission, though the ads you see may differ. You can change this setting later in the device Settings app.
5. Sharing with Third Parties
Except as required by law, we do not sell or provide user information to third parties ourselves. However, advertising networks may collect and process the information described above for ad delivery.
6. External Transmission / Analytics
The App does not send user data to our own analytics servers. External transmission related to advertising depends on the advertising networks we use.
7. Information Management
Information used by the App is handled under iOS permission controls and on-device storage. You can change advertising and tracking-related settings on your device.
