Privacy Policy

Last updated: May 30, 2026

Welcome to JFT Guru and Nepali Kanji, products of Tech Bato Pvt. Ltd. We respect your privacy and are committed to protecting your personal data. This privacy policy informs you how we handle your personal data across our website (jftguru.com), the JFT Guru Mobile Application, and the Nepali Kanji Mobile Application (collectively, the "Services"), and explains your privacy rights.

Nepali Kanji — Local-Only Data

The Nepali Kanji app does not require account creation. No name, email address, phone number, or personal identity data is collected. Your kanji study progress, study streak, and favorites are stored locally on your device only (via SQLite database and SharedPreferences) and are never transmitted to our servers. Uninstalling the app permanently deletes all local data.

1. Information We Collect

Note: Sections 1a (Identity Data) and 1b (Contact Data) apply to JFT Guru only. The Nepali Kanji app does not collect these data types. Technical Data (including AD_ID via AdMob) applies to both apps.

We may collect, use, and process the following data through our website and JFT Guru mobile app:

Identity Data: Full name, username, Japanese proficiency level (N1–N5), and profile avatar.
Contact Data: Email address and Phone Number.
Technical Data: IP address, device model, operating system version, browser type, and unique device identifiers (including Advertising ID / AD_ID).
Usage Data: How you navigate our Services, mock test scores, and practice history.
Audio Data: Voice recordings captured during "Speaking Coach" sessions within the JFT Guru app, along with the speaking scenario prompt text. These recordings are sent to our own AI server (JFT Guru AI) for speaking performance evaluation. Audio data is processed in real-time and is not permanently stored after evaluation. This data is not used for identifying you personally, advertising, or profiling.

2. How We Use Your Data

We use your data on both the website and JFT Guru mobile app to:

Register your account and maintain your progress across all platforms.
Process AI-based speaking evaluations.
Serve personalized or non-personalized advertisements via Google AdMob/AdSense.
Improve our educational content, app performance, and user experience.

3. Third-Party Services & SDKs (App & Web)

Our Services use several trusted third-party tools that may collect data:

Google Mobile Ads (AdMob): Used in the mobile apps to serve ads. They may collect your Advertising ID to provide tailored ads.
Firebase Analytics: Used to understand app performance and usage patterns.
Microsoft Clarity: Used on both website and app for behavior analysis (heatmaps and session replay). Data is handled per the Microsoft Privacy Statement.
Google Login: For unified authentication on JFT Guru. We only access your name and email from your Google Profile.
Apple Sign-In: For iOS authentication on JFT Guru. We only access your name and email as provided by Apple.
JFT Guru AI (Speaking Coach): The "Speaking Coach" feature uses our own AI model, developed and hosted by Tech Bato Pvt. Ltd. on a private cloud server. When you use this feature, your voice recording audio and the speaking scenario prompt text are sent to our server for real-time evaluation. Audio is processed in real-time and is not permanently stored after evaluation is complete. This data is not used for advertising or profiling.
Google Gemini AI: Used to power the "AI Weak Point Analysis" feature, which reviews your incorrect exam answers and generates personalized study suggestions. When you request an analysis, your incorrect question content (question text, correct answer, and your answer) is sent to Google Gemini AI (Google LLC) for processing. No personal identity data is included. Data is processed in real-time and is not stored permanently by Google after the response is generated. Google's data handling is governed by the Google Privacy Policy.
Flutter TTS (Text-to-Speech): Used in the Nepali Kanji app to pronounce Japanese words aloud. This service plays audio locally on your device only — it does not record, transmit, or store any user audio.

4. Account Deletion & Data Retention

We provide unified account management for JFT Guru across all platforms:

In-App Deletion: Within the JFT Guru mobile app, go to Profile > Edit Profile and tap "Delete Account".
Web Deletion Link: You can also request permanent account deletion via our official web portal: https://jftguru.com/delete-account.

Once deleted, your JFT Guru account and all associated scores/history will be permanently removed from our servers within 30 days.

Nepali Kanji: The Nepali Kanji app does not use accounts. To remove all app data, simply uninstall the app from your device. All locally stored progress, streaks, and favorites are permanently deleted upon uninstallation.

4a. Mock Test Data Retention Policy

Our database has now crossed 50,000+ mock test submissions from students across all platforms. To maintain optimal performance and protect your privacy, we have adopted the following data retention policy effective June 5, 2026:

Retention Period: We retain mock test records, practice session data, and exam submission history for a rolling period of 1 month (30 days) only.
Automatic Deletion: Mock test data older than 30 days is automatically and permanently deleted from our servers. This applies to all students equally — no exceptions.
Scope: This policy covers all mock test submissions, practice attempt logs, score histories, and related session data stored in our database. It applies to all users on both the JFT Guru website and mobile application.
What is NOT deleted: Your account profile, subscription/purchase records, and payment receipts are not affected by this policy and are retained for as long as required by applicable law or until you request account deletion.

We encourage students to review and note their progress regularly. If you need a record of your practice history, please do so within the 30-day retention window as data cannot be recovered once deleted.

5. Data Security

We implement strict security protocols to prevent your personal data from being accidentally lost or accessed in an unauthorized way. All communication between our website/app and the server is encrypted using SSL (HTTPS).

6. Payments

Digital purchases on JFT Guru are processed by Dodo Payments or verified via manual receipt submission. We do not store your credit card or financial credentials on our servers.

Nepali Kanji is a free app and contains no in-app purchases or billing of any kind.

7. Open Data Attribution (Nepali Kanji)

The Nepali Kanji app uses the following open-licensed datasets to provide kanji and dictionary data:

These datasets are used under their respective open licenses. No data is sent to these organizations, and they have no involvement in this application.
