Privacy Policy

Last updated: October 29, 2026

This Privacy Policy explains how Kahani Express handles information when you use our website, mobile application, stories, games, and related learning services. It also explains how we handle information received through Google sign-in.

1. Information we collect

Account information: Your email address, authentication identifier, and the profile information you provide. Email-and-password accounts use Firebase Authentication to manage credentials. When you sign in with Google, we do not receive your Google password.
Learning profiles and activity: Information you enter, such as a learner's name, age, avatar, language and reading preferences, and, where applicable, school or class details. We also process reading progress, quiz and game results, rewards, and drawings associated with the account.
Service and device information: App and website interactions, session and account identifiers, device or platform information, performance and error diagnostics, and a notification token when notifications are enabled. Some activity records are associated with your account; they are not all anonymous.
Purchases and communications: Subscription status and purchase identifiers needed to provide paid features, and information you send in feedback or support requests.

2. Google sign-in and Google user data

Access: If you choose Google sign-in, Kahani Express requests basic profile and email permissions. Google and Firebase Authentication may provide your name, email address, profile picture, Google account identifier, and authentication information, such as an ID token, to establish your identity. The account flow uses your email address and a Firebase user identifier, together with the learning-profile details you enter. Google sign-in does not request access to Gmail messages, Google Drive files, contacts, Calendar, or YouTube account data.

Use: We use Google sign-in information to authenticate you, create or recognize your Kahani Express account, maintain your signed-in session, and associate the account with your profile and learning activity. We do not use Google user data for advertising, sell it, or use it to train general-purpose AI or machine-learning models.

Storage: Google sign-in is processed through Google and Firebase Authentication. Account and profile records are stored in Firebase services and our application database, which uses MongoDB. Authentication state and profile details may also be retained on your device or browser so you can stay signed in. Signing out ends your local signed-in session; it does not delete your account.

Sharing: Google and Firebase process sign-in information to authenticate you. Our hosting and database service providers process account information as needed to operate Kahani Express. We do not share Google user data with advertisers or data brokers. Account-linked information is accessible to authorized personnel when necessary to operate the service or address a support or security issue.

Disconnecting Google: You can remove Kahani Express's access through your Google Account connections settings. Removing access prevents future use of that Google authorization; it does not automatically delete information already stored in your Kahani Express account. To request deletion of that information, use the account-deletion options below. Removing Google access may affect your ability to sign in with Google.

Kahani Express's use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including its Limited Use requirements where applicable.

3. How we use other information

We use account, learning, and service information to provide stories and activities, save progress and preferences, manage access and subscriptions, deliver enabled notifications, respond to requests, diagnose errors, and improve the service. Where school or class features are used, relevant profile and learning activity may be available to authorized participants managing that learning relationship. Do not provide information about another person unless you have authority to do so.

4. Service providers and other disclosures

We use service providers for authentication, databases, hosting, analytics, diagnostics, notifications, and subscription management. These services may process account identifiers, technical information, or other information needed for their function; this processing is not limited to anonymous data. Firebase provides authentication, database, analytics, and performance services. App stores and RevenueCat process purchase and subscription information when those features are used. We do not sell your personal information or share it with third-party advertisers or marketing agencies.

If you choose to play an embedded video or follow an external link, the relevant provider, such as YouTube, may process information under its own privacy policy. We may also disclose information when required by law or reasonably necessary to protect users and the security of the service.

5. Retention and security

We retain account and profile information while the account is maintained and use it for the purposes described above. Retention of activity and diagnostic records depends on the record and the service that processes it. You can request account deletion or ask about retained information using the options below. Contact us if you need details about retention of a particular record, including logs, backups, or records held by a service provider.

We use authenticated access and HTTPS connections to help protect account information. Access is restricted according to the function of the service and the user's role. No storage or transmission system can be guaranteed completely secure.

6. Your choices and account deletion

You can update available profile settings in the app. To delete your account, open the app's Edit Profile screen and choose Delete Account, or sign in and visit the website's account-deletion page. The mobile deletion process requests removal of the application account and associated learning records, the Firebase profile record, and the Firebase Authentication account. If deletion reports an error or you cannot access your account, contact kahanikidsapp@gmail.com for help and confirmation of any remaining cleanup.

You may also contact us to request access to, correction of, or deletion of your information. We may need to verify that you are authorized to make the request. Deleting a Kahani Express account does not delete your Google account. If you have an app-store subscription, manage or cancel it separately through the store where you purchased it.

7. Children and learning profiles

Kahani Express offers children's learning content and parent, guardian, teacher, and school features. Learning profiles can contain the learner information and activity described above. Parents, guardians, or authorized educators should supervise use and provide information about a child only when authorized. If you believe a child's information has been provided without appropriate authorization, contact us to request review or removal. This privacy notice does not itself obtain parental consent.

8. Changes to this policy

We will update the date at the top of this page when this policy changes and provide additional notice or request consent when required before using information in a new way.
