Curigo

Learn anything. Your way.

Curigo is a native learning app.

Privacy

When you sign in with Google or Apple, Curigo receives your account identifier, email and, if provided, display name. Apple lets you hide your email address. We do not receive your Apple or Google password or access your email messages.

Your courses, lesson progress, profile and submitted feedback are stored in Cloudflare D1 to synchronize your devices. Session credentials are stored in the Apple Keychain. Google tokens are used only for sign-in and are not retained. Apple refresh tokens are encrypted on the server solely for authentication revocation when you delete your account. Deleting your account removes your associated data and revokes its Apple authorization. Apple and Google sign-ins are separate accounts; Curigo does not merge accounts by matching email addresses.

To adapt learning, Curigo records submitted answers, correctness, matching errors, foreground response time and whether a question was interrupted or reported. Unsent records stay on your device until synchronization. These records are private and are not included in shared courses or used for advertising tracking. Detailed question observations are retained on the server for up to one year after synchronization; compact learning summaries remain with your courses. Deleting your account removes these records.

When you request AI content, your topic, learning preferences and relevant previous lesson content and answer summaries are sent through Cloudflare to OpenAI to generate lessons. Do not submit sensitive personal information. AI output may contain errors.

学習を調整するため、回答・正誤・組み合わせのミス・問題を見ていた時間・中断や問題報告を記録します。未送信の記録は端末に保存し、同期後も非公開で管理します。広告追跡には使用しません。詳細な回答記録は同期後最長1年間、学習要約はコースとともに保持し、アカウント削除時に削除します。AI生成を依頼すると、関連する過去の内容と回答の要約をOpenAIへ送信します。

Product usage analytics

To improve Curigo and understand feature adoption, we store account-linked screen views, feature actions, lesson and generation outcomes, subscription interactions, app version, language and short-lived session identifiers in Cloudflare. These events do not include question prompts, chat messages, names, emails or advertising identifiers. Pending events are stored on the device or browser for up to 7 days (at most 1,000 events per account); server events are retained for up to 365 days and removed when the account is deleted. We do not track activity across other companies' apps or sites.

Curigoの改善と機能の利用状況の把握のため、画面の表示、機能の操作、学習・生成の結果、購入画面での操作、アプリのバージョン、言語、一時的なセッションIDをアカウントに関連付けてCloudflareに保存します。このイベントに問題文、AIとの会話、氏名、メールアドレス、広告識別子は含めません。未送信分は端末・ブラウザに最長7日間（1アカウント最大1,000件）、サーバーでは最長365日間保存し、アカウント削除時に削除します。他社のアプリやサイトをまたぐ追跡は行いません。

AI lesson questions

When you ask the Pro lesson tutor, Curigo sends the current question, choices, correct answer, your selected answer, explanation and recent conversation to OpenAI through Cloudflare. The tutor may use web search, including search queries derived from the conversation. Chat history stays in the current lesson on your device and is not saved to Curigo's database. OpenAI processing is subject to its API data policies.

ProのAI質問では問題・選択肢・正解・選んだ回答・解説・直近の会話をCloudflare経由でOpenAIに送信します。会話から検索語を作りWeb検索を使うことがあります。会話履歴は端末の現在のレッスン内に保持し、Curigoのデータベースには保存しません。OpenAIでの処理には同社のAPIデータ方針が適用されます。

Web payments and browser storage

Web payments are processed by Stripe. Your account identifier, email, subscription and payment status are used to enable and manage Curigo Pro. Curigo does not receive card numbers. Browser session credentials are stored in session storage; account-scoped learning caches, drafts and pending observations are stored locally until synchronized or cleared. Manage and end an active web subscription before deleting your account.

Web決済はStripeが処理し、Curigoはカード番号を受け取りません。アカウントID・メールアドレス・契約と支払い状況を連携してProを管理します。ブラウザではログイン情報をセッション領域に、下書き・キャッシュ・未送信の学習記録をアカウント別に保存します。Webの契約が有効な場合は、先に契約を終了してからアカウントを削除してください。

Course discovery

We store your course likes and learning starts to show aggregate like and learner counts and recommend courses. Recommendations use learning genres, likes and recent activity. For public courses, signed-in users can view learner display names. The creator receives an in-app notification with the learner display name when their course is first played by that learner. Email addresses, answers and private learning history are not shared. You can remove a like; deleting your account removes its likes and usage records.

教材へのいいねと学習開始を記録し、合計数の表示と教材のおすすめに利用します。おすすめには学習ジャンル、いいね、最近の利用状況を使います。公開教材では、ログインしたユーザーが学習者の表示名を確認できます。その学習者が教材を初めて遊んだとき、作成者のお知らせに表示名が届きます。メールアドレス・回答・非公開の学習履歴は共有しません。いいねは取り消せ、アカウント削除時にはいいねと利用記録も削除されます。

Attachments, purchases and notifications

Original attachments are retained in private Cloudflare storage and referenced when generating later lessons. Original files are not distributed to other learners, including for public courses. Files referenced by a course are retained with it; unused uploads and files belonging only to deleted courses are removed by scheduled cleanup after seven days from upload. Account deletion also removes original files.

元の添付資料をCloudflareの非公開ストレージに保存し、各マスや続きの生成でも参照します。公開コースでも元ファイルを他の利用者へ配布しません。コースで利用中は保持し、未使用・削除済みコースだけの資料はアップロードから7日経過後の定期処理で削除します。アカウント削除時にも削除します。

If you attach photos or files, their selected contents are processed through Cloudflare and OpenAI to create the requested learning material. We also send learning content to OpenAI to check for inappropriate material. This filter can make mistakes and is not a guarantee of suitability for every child.

RevenueCat processes your Curigo account identifier and purchase information, including products, transactions, renewal and expiration status, to enable purchases, restoration, subscription access and purchase analytics. Apple handles payment; Curigo does not receive your payment card details.

When you enable completion notifications, we store your APNs device token, its signed-in session, notification language and delivery environment. These are used for requested course-completion notifications, not advertising tracking. Daily learning reminders are scheduled on your device.

Published courses can be viewed by other users; your intake answers and private learning history are not included. You can delete your own courses and report or block other courses. Account deletion removes Curigo account data; it does not cancel an Apple subscription or necessarily delete transaction records retained by Apple or RevenueCat under their policies.

添付・購入・通知について

選択して添付した画像やファイルは、教材作成のためCloudflareを通じてOpenAIで処理します。不適切な内容を検査するためにも教材をOpenAIへ送信します。フィルターには誤判定や見落としがあり、すべての子どもへの適合を保証するものではありません。

RevenueCatにCurigoのアカウントIDと購入・取引・更新・有効期限の情報を連携し、購入、復元、有料機能の判定と購入分析に使用します。決済はAppleが処理し、Curigoはカード情報を受け取りません。生成完了通知にはAPNs端末トークン、ログイン中のセッション、言語、配信環境を使用し、広告追跡には使いません。毎日の学習リマインダーは端末上で予約します。

公開したコースは他の利用者が閲覧できますが、アンケートの回答や個人の学習履歴は公開しません。自分のコースの削除、他のコースの通報・ブロックができます。アカウント削除ではCurigoのアカウントデータを削除します。Appleのサブスクリプションの解約は別途必要で、AppleやRevenueCatが保持する購入記録には各社の方針が適用されます。
