Data deletion request
How to delete your data in the app（アプリ内での削除手順）
You can delete some or all of your recipe data without deleting your account.
- Open the Recipe Collection app.
- Open the recipe or book you want to remove.
- Use Edit / delete actions to remove recipes, books, or images.
- If you are signed in (Google, email, or guest), cloud-synced copies are updated or removed when sync runs after deletion.
アカウントを削除しなくても、レシピ・本・画像はアプリ内から削除できます。ログイン中はクラウド同期後にクラウド側も更新・削除されます。
Request help（削除の依頼）
If you cannot delete data yourself, request deletion from inside the app:
- Open Menu.
- Tap Send feedback（要望を送る）.
- Write that you want data deletion for Recipe Collection, and include your login email if you use email/Google sign-in.
We will process reasonable deletion requests for cloud-stored account-related data.
What is deleted / retained（削除・保持）
Deleted when you remove items in the app: selected recipes, related images, and synced cloud recipe documents for those items.
May be retained: Firebase authentication account records until you delete the account or request account closure; aggregated/anonymous analytics or ad identifiers handled by Google AdMob according to Google’s policies; server logs for a limited period for security and abuse prevention (typically up to 90 days).
Device data: uninstalling the app removes local on-device data.
