Telugu Varnamala · Android app · version 1.0.0

Privacy Policy

Prepared on 2 October 2026.

About this policy

This policy describes the Telugu Varnamala mobile application. The app works with bundled learning material. You can use it without an account, or log in with the same account as the Telugu Varnamala website so your progress continues on both.

Learning information on your device

The app stores completed lessons, lessons to review, XP, activity dates and counts, the last lesson, up to 100 recent quiz/game results, and your transliteration and slow-audio preferences in app storage on your device. This enables progress tracking and resuming learning. Without an account, this information stays on your device.

Your account

If you create an account, the app asks for your name, your mobile number with its country code, and a 4-digit PIN. We store your name, mobile number and learning progress on our server so you can continue on the website and in the app. The PIN is stored only in a scrambled (hashed) form that cannot be read back. On the device, the app keeps a sign-in token in Android's secure storage, so you stay logged in until you log out.

We record when you create the account, log in, log out, reset your PIN and practise. Authorized Telugu Varnamala staff can see your name, mobile number, progress and this activity in an admin dashboard to support learners. We do not send text messages, make calls or use your number for advertising.

On Android, the login screen can offer the mobile number from your SIM using Google Play services. The number is filled in only if you tap it; the app does not read your SIM, call log, contacts or messages.

Lessons, fonts, images and pronunciation clips are packaged with the app rather than requested from a remote media service.

Optional microphone access

When you choose “Record my voice” in practice, the app requests microphone permission to let you record and replay your own voice. Each recording lasts at most 15 seconds. You can decline permission and use the other learning activities. There is no speech recognition service or automatic pronunciation scoring.

Recordings are temporary files in the app's device cache. The app does not upload or include them in progress exports. It attempts to stop recording when backgrounded and remove recordings when leaving practice or starting another recording. Force-closing the app or a cleanup error can leave temporary files until the operating system clears the cache or you clear the app's cache/storage. There is no guaranteed time for automatic cache removal.

Exports you choose to share

Settings → Export progress creates a JSON file containing learning progress and opens the operating system's share sheet. You choose a destination. The export excludes voice recordings and preferences. The app attempts to delete its temporary export file when sharing finishes. Copies saved or sent to other apps remain under your control and that destination's policies; resetting this app does not remove those copies.

Services, permissions and sharing

This implementation has no advertising, Advertising ID integration, analytics SDK, remote crash-reporting SDK, payments or subscriptions. It has no features using location, camera, contacts, health data or notifications. Expo and React Native libraries run the interface, local audio, storage and sharing; their use does not by itself mean your learning data is sent to Expo.

With an account, your name, mobile number and learning progress are sent over HTTPS to the Telugu Varnamala server; voice recordings never are. We do not sell or share these records with third parties. Sharing an export is your choice. Google Play and your device provider may process information under their own policies when you download or manage apps.

The verified Android release configuration enables operating-system backup. Depending on your device settings and provider, app data may be copied to a device backup or restored on another device. Separately, an account keeps your progress on our server. Manage device backup copies through your device settings/provider.

Retention and deleting your data

Account information and progress remain on our server until you ask us to delete the account. Device-only progress and preferences remain in app storage until you clear them or the device removes them. Settings → Reset progress → Yes, reset progress clears progress while keeping preferences. To remove preferences and cached files too, use Android Settings → Apps → Telugu Varnamala → Storage (or Storage & cache) → Clear storage/data. Clearing only cache does not erase learning progress. Menu names vary by device.

Uninstalling ordinarily removes app-local data, but copies in exports or device backups may remain and restored backups may reintroduce data. Manage those copies separately through the destination app or backup provider. See the data deletion instructions.

Security and your choices

Data on the device is kept in application storage governed by Android's access controls; the sign-in token uses Android's secure storage. Account data travels over HTTPS. A 4-digit PIN is easy to guess, so the server limits wrong attempts. Anyone who knows your mobile number can choose a new PIN with “Forgot PIN”, which logs out your other devices; tell us if this happens unexpectedly. Protect your device and be careful where you share progress exports. No storage system can promise absolute security.

You can review progress, export it, reset it, clear app storage, or revoke microphone access through device settings. You can log out at any time. The developer cannot remotely retrieve or delete learning records that remain only on your device. For privacy questions or rights requests, use the contact below. Do not send a child's voice recording or personal information to request help.

Children and families

Telugu Varnamala is intended for learners aged 5–13, including children. Parents and guardians can help learners manage microphone permission, sharing and deletion. An account is optional; a parent or guardian should create it with their own name and mobile number. Voice practice is processed locally. Android microphone permission is not a substitute for any parental consent required by applicable law.

Account records are stored on the server that hosts the Telugu Varnamala service. Recordings are never transferred. A destination chosen for export, your device backup provider, or your support email provider may process information elsewhere under its own arrangements. Review this policy whenever features or data practices change and update the effective date.
