Kakimashou privacy policy
This policy explains what data the Kakimashou app for iPhone handles.
Controller
Benkyo, the name under which this website and its apps are published. Contact: [email protected].
Your progress stays on your iPhone
Your progress, reviews, sets and settings are stored only on the device. There are no accounts and no server of our own: nobody else sees them. If you delete the app, they are deleted.
Camera
The camera is used to recognise kanji in real-world text. The image is analysed on the iPhone itself with Google ML Kit text recognition, which works offline. The photo is not saved to your photo library or sent anywhere. As part of ML Kit, Google may receive performance and usage metrics for this feature and send model updates (ML Kit terms); it never receives the image. The app only asks for camera permission when you open that feature.
Ads (Google AdMob)
The free version shows ads from Google AdMob. To serve them, Google may collect data such as your IP address, device identifiers and how you interact with ads.
- Before showing ads, iOS asks whether you allow tracking (App Tracking Transparency). If you say no, the advertising identifier is not shared.
- In the European Economic Area, the app shows Google’s consent form, where you choose whether ads can be personalised.
Google handles this data under its own policy: how Google uses information from sites or apps that use its services.
Purchase to remove ads
The purchase is handled by Apple. The app only receives confirmation that it went through; it never sees your payment details.
Fonts
The first time it opens, the app downloads its Japanese fonts from Google Fonts servers, which receive your IP address for that download.
External links
If a kanji is not in the app, you can look it up on Jisho.org. It opens in your browser and is governed by that website’s policy.
Age
The app is intended for people aged 13 and over.
Your rights
You can exercise your rights of access, rectification, erasure, objection, restriction and portability by writing to [email protected], and complain to the Spanish Data Protection Agency (aepd.es). For ad data, you can also contact Google.
