HyoMemo ("the app") is an iPhone and iPad app provided by Tatsuki Izumi ("the developer"). This policy explains what information the app handles.
Tables, rows, categories, and settings you create are stored on your device (and also in your own iCloud Drive if you turn on iCloud sync, described below). They're never sent to the developer's servers, and the developer never views or keeps them.
Files you export with Backup or Export are saved wherever you choose (the Files app, iCloud Drive, other apps, and so on), and are handled under that service's terms.
When you turn on Sync with iCloud in Settings, your tables are stored in your own iCloud Drive (storage provided by Apple) and shared across iPhone and iPad signed in to the same Apple Account. Data moves only between Apple's servers and your devices; the developer has no access. It's handled under Apple's Privacy Policy. You can turn sync off anytime to keep data on your device only.
The Home Screen widget and adding items from other apps' share sheets exchange data through a shared area on your device (App Group). Nothing leaves your device.
The free version uses Google AdMob, an ad service provided by Google, and Google User Messaging Platform (UMP), which manages ad consent. To serve and measure ads, Google's SDK may collect:
This information is handled under Google's Privacy Policy and the consent choices shown on screen. The app never includes table names, item contents, or anything else you enter in ad requests. The app doesn't ask for permission to track you across apps (App Tracking Transparency).
After you buy Remove Ads, the app stops requesting ads from the ad SDK.
Remove Ads is purchased through Apple's App Store (StoreKit). The app never collects or stores payment details such as card numbers. Purchase status is checked using transaction information provided by Apple.
