Privacy Policy

Last updated: 13 October 2026

This policy explains what Intelligent Translator (“the app”), operated by Rajib Rai (“we”), collects, why, who it is shared with, and the choices you have. Contact us at devapp.rajib@gmail.com.

What we collect

• Account information. When you sign in with Google we receive your Google account's email address, name and a user identifier from Firebase Authentication. Before you sign in, the app uses an anonymous identifier instead.
• Device identifier. On Android the app sends the device's Android ID so free uses cannot be claimed again by reinstalling. We never store it: we keep only a one-way keyed hash of it.
• Content you submit. Text you translate or study, and photos sent for online text recognition, are sent to our server and to the third-party AI model providers that process them. We keep translation results in server memory for up to 24 hours to answer repeated requests faster; your translation history is stored only on your device.
• Credits and purchases. Your credit balance and its history (purchases, ad rewards, credits spent, credits expired). Payments are processed by Google Play; we never receive your card or bank details, only a purchase record to verify and credit it.
• Usage and diagnostics. An anonymous install identifier, how many AI tokens each request used and what it cost, app usage events (Firebase Analytics), crash reports (Firebase Crashlytics), and, if you answer it, the optional student survey.
• Advertising. If you choose to watch rewarded ads, Google AdMob and its mediation partners may collect your device's advertising ID and related data under their own policies, according to the consent choices you make.

Why we use it

• To provide translation, Study and text recognition.
• To keep your credit balance, verify purchases and ad rewards, and apply free daily allowances fairly.
• To prevent abuse of free allowances.
• To understand costs, fix crashes and improve the app.

Who we share it with

• Google (Firebase Authentication, Firestore, Analytics, Crashlytics, AdMob and Google Play) as our service providers.
• Third-party AI model providers, only the content needed to process your request.
• Authorities, where the law requires it.

We do not sell your personal data.

How long we keep it

• Account and credit data: until you delete your account.
• The keyed device hash: kept after account deletion, because it holds no personal data and is what prevents free allowances from being claimed again.
• Cached translation results: up to 24 hours, in memory only.
• Usage and cost records: kept in aggregate form for accounting.

Your choices and rights

• Delete your account in the app under Settings → Account → Delete account, or as described on our account deletion page.
• Change your ad consent choices in Settings → Account → Ad privacy choices.
• Depending on where you live, you may have the right to access, correct or delete your data, or to object to its processing. Contact us to use them.

Children

The app is not directed to children under 13, and we do not knowingly collect their personal data.

Security

Data is sent over encrypted connections. Access to stored data is limited to the service accounts that need it.

Changes

We will post any change to this policy on this page and update the date above.
