Bolo is built and maintained by Lavkesh Dwivedi, an independent developer based in Dallas, Texas, USA. This is not a company. Contact via lavkesh.com.
Lavkesh Dwivedi does not operate any server, database, or backend that receives data from Bolo. The app has no accounts, no logins, no analytics, no advertising, no tracking pixels, no cookies (beyond what your own browser may set automatically), and no third-party data sharing of any kind. Nothing about you or your child is transmitted to this developer.
| Feature | What happens | Data leaves your device? |
|---|---|---|
| Voice playback (all modes) | Browser text-to-speech speaks a word. Chrome may use Google's voices, Edge may use Microsoft's. | Only the word text (e.g. "cat") may go to the voice provider. No child identity data. |
| Microphone - Hear and Repeat | Your browser records a short audio clip and sends it to Google (Chrome) or Microsoft (Edge) for speech recognition. Bolo receives only the resulting text and checks if it matches the target word. | Yes. Audio goes directly from your browser to Google or Microsoft. Bolo never receives or stores the audio. |
| Camera - Show and Tell | Live video is analyzed entirely on your device by TensorFlow.js (coco-ssd model). No image or video data is sent anywhere. | No. All camera processing is on-device only. |
| Settings (localStorage) | Language preference, chosen voice, pitch, rate, and volume are saved in your own browser's local storage on your device. | No. This data never leaves your device and is not accessible to this developer. |
| Offline cache (service worker) | App files are cached on your device so the app works without an internet connection after the first load. | No. Contains only app code, no personal data. |
This is the most important section to understand. When your child uses Hear and Repeat and taps the mic button:
This audio-to-server step is handled entirely by your browser using the Web Speech API, a built-in browser feature. Bolo has no control over what Google or Microsoft do with that audio. Their handling is governed by their own policies:
If you prefer that no audio be sent to any third-party server, simply do not use the Hear and Repeat activity. All other activities (Tap and Learn, Picture Match, Show and Tell, My Family) do not use the microphone at all.
Bolo contains no advertising networks, no analytics scripts (no Google Analytics, no Mixpanel, no similar services), no social media plugins, and no tracking of any kind. There are no cookies set by this developer. There is no monetization of user data.
Bolo is designed for children ages 1 to 6. Under the U.S. Children's Online Privacy Protection Act (COPPA):
Because Bolo retains no data, there is nothing to request, review, or delete on this end. For concerns about audio that Google or Microsoft may have processed, contact those companies directly using the links above.
Bolo does not collect, sell, share, or process personal data of any Texas resident. No data is sold to third parties. No targeted advertising is conducted. No personal data is processed for profiling. These representations apply to all users regardless of location.
Bolo does not collect, store, process, or transmit personal data of any user, including users in India. No personal data about children or parents is processed by this app or by this developer.
Bolo does not collect personal data from users anywhere in the world. No data is transferred internationally by this developer. Users in the European Economic Area, the United Kingdom, Canada, or any other jurisdiction should note that this developer receives no personal data from use of this app.
If anything meaningful changes, the "Last updated" date above will change. Since the app collects no data of its own, an update would most likely reflect a new feature being added that changes how the browser interacts with third-party services.
