Information we handle

When you sign in with Google, Firebase Authentication handles your account information, including your name, email address, profile information made available by Google, and app account identifier. We use your account identifier to associate your exam pass with your account.

For exam-pass purchases, we handle Google Play purchase tokens, product identifiers, purchase status, verification timestamps, account association and pass validity. Google Play processes your payment. Our app does not receive your card number or banking credentials.

Practice attempts, scores, answer review information and subject performance are stored on your device and linked to your app account identifier. Signed-out guest history is stored separately. They are not currently uploaded to our purchase backend. Android device backup may include local app data, depending on your device settings.

Firebase App Check and Google Play Integrity process app and device security signals to help prevent unauthorised access. Google Cloud services process operational information such as request logs, timestamps and technical errors. Firebase Remote Config supplies app configuration, including the exam date.

If you email us, we receive your email address and the information you include. Please do not send passwords, payment credentials or purchase tokens.

How we use information

We use information to sign you in, verify and restore purchases, apply refunds or revocations, enforce pass validity, protect the service, diagnose problems and respond to support or privacy requests. We do not sell your personal information. The current app does not include advertising SDKs or Firebase Analytics or Crashlytics integrations.

Service providers

We use Google Sign-In, Firebase Authentication, Firebase Remote Config, Firebase App Check, Google Play Integrity, Google Play Billing and Google Cloud hosting and database services. These providers process information to deliver their services under their applicable terms and privacy policies. Processing may occur outside your country. The purchase database and functions are configured in Google's Mumbai region; this does not mean every Google service processes all information exclusively in India.

Retention and deletion

Account information is retained while your app account exists. Purchase records are used to maintain your entitlement and prevent purchase misuse. We also maintain limited operational logs.

Account-linked purchase quotes, receipts, raw purchase tokens, pass records and request-limit records are removed during verified account deletion. A hashed account identifier, deletion state and deletion timestamps are retained while the purchase service operates to prevent old requests and payment notifications from recreating deleted records. The marker contains no email address or purchase token. Routine technical logs are retained for 30 days. Support correspondence is removed 90 days after the issue is resolved. Google Cloud's required audit bucket retains its records for 400 days. Google also independently maintains records under its own policies.

You can contact mathodlab.support@gmail.com to request access, correction or deletion of your information. You can use Pass → Help & information → Delete account in the app, verify with the same Google account, and confirm deletion. If you no longer have the app, email the support address from your sign-in email address to request deletion; we verify account ownership before processing. We aim to complete verified email deletion requests within 30 days and will inform you if a request needs additional time. Deleting your app account does not delete your Google account or automatically refund a Google Play purchase. Signing out is not account deletion.

In-app deletion removes the deleted account's practice history from that device and preserves other accounts' and guest history. History stored on other devices and Android backup copies is not remotely erased by this process. Clear local data on those devices if necessary; backup copies are controlled through your Android/Google backup settings. A web/email deletion request cannot itself erase device-local history.

Children and privacy questions

Changes

We will update this policy when our practices change and show the revised effective date. Material changes will be communicated where appropriate.
