Bionic Ear Privacy Policy

Effective 28 October 2026 · Zelicra Technologies Private Limited

Bionic Ear helps you hear one voice in a noisy room and turns your ebooks into audiobooks. Both run on your phone. It works without a Zelicra account, without our servers, without ads and without analytics.

Microphone

When you start listening, Bionic Ear reads the microphone, picks out the voice you chose and plays it to your headphones as you hear it. The short sample it takes of that voice is kept in memory only while you listen. Bionic Ear does not record, save or upload microphone audio.

While it listens, Android shows a notification for the service that keeps the microphone on.

Books and audiobooks

When you open a book (EPUB, PDF or TXT), Bionic Ear saves a copy in its own storage on your phone, and the audiobook it makes from it is saved there too. Books and audio are never uploaded.

Voice and speech models

The first time you use a feature, Bionic Ear downloads the model it needs from GitHub (github.com) or Hugging Face (huggingface.co). Those sites see your IP address, as with any download, under their own privacy policies. Nothing about you or your books is sent with the download.

Purchases

Bionic Ear Pro is sold through Google Play. Google processes the payment under the Google Privacy Policy. The app checks the purchase on your phone; Zelicra does not receive your payment details.

Data we do not collect

Bionic Ear does not send any of your data to Zelicra or to anyone else. It does not collect your name, email, contacts, location, device identifiers or usage analytics, and it does not share or sell data.

Deleting your data

Everything Bionic Ear keeps is on your phone. Clearing the app's storage or uninstalling the app deletes all your books, audiobooks, models and settings.

Children

Bionic Ear is not directed at children under 13.

Changes

If this policy changes, the new version will be posted here with a new effective date before an app version that relies on it is released.
