Privacy Policy
Effective 10 November 2026
The short version: Bas Bolo doesn't store your audio, text or video. We process it live and let it go. To work, your speech is sent to our speech and translation partners (Gnani AI and our translation provider), who handle it under their own terms.
1. Who we are
Bas Bolo ("we", "us") is a live tour translation service at basbolo.app, built in Solapur, Maharashtra, India. This policy explains what happens to your information when you use the website and the app.
2. What we process, and what we keep
| Information | Why | Kept by us? |
|---|---|---|
| Your voice while you hold the talk button (or while a guide's hands-free mode is on) | To turn speech into text | No. Processed in server memory only and discarded. |
| Transcripts and translations | To show subtitles and speak them to others in the room | No. Held in server memory for the live room (a short buffer lets a dropped phone catch up) and deleted when the room closes. |
| Translated voice audio | To speak each sentence in each listener's language | No. A short in-memory cache avoids paying twice for the same phrase; it is never written to disk. |
| Guide video (virtual tours) | To stream the guide's camera to the room | No. Streamed live through our video provider, not recorded by us. |
| Your display name, chosen language and "I am male / female" choice | To show you in the room, translate to you and voice your words with the right grammar | Only for the live room. Your phone also remembers them for next time (see section 5). |
| Guide account (Google sign-in): name, email, account ID | So only the real guide can run their tour | Yes, by Google Firebase Authentication, until you ask us to delete it. |
| Tour metadata: tour ID, guide account ID, live or virtual, start and end time, duration, peak number of people, how many people per language, error counts | To run and improve the service | Yes, in Google Firestore. It contains no voice, no text and no names of tourists. |
| Technical logs (time, room code, error type, IP address in our host's access logs) | Security and fixing problems | Short term. Our server logger is built so it cannot write what anyone said. |
3. Partners who process data for us
- Gnani AI (speech-to-text "Prisma" and text-to-speech "Timbre"): receives speech audio and text to convert them.
- Sarvam AI (translation): receives the text of each sentence to translate it.
- LiveKit (virtual tours only): carries the guide's live video.
- Google Firebase: guide sign-in and the tour metadata above.
- Render: hosts our server.
- Google Fonts: serves the fonts, so your browser contacts Google when pages load.
Each partner handles data under its own terms and privacy policy. We send them only what the feature needs.
4. Recording on your own phone
In virtual tours anyone can tap Record. The video is made and kept on that person's own phone and is never uploaded to us. Other people in a room can always record their own screen or audio, so please behave as you would in any group.
5. What stays on your device
Your browser remembers your name, language, gender choice and app settings (text size, sounds, noise filters) so you don't have to type them again, plus a temporary ID for the room you are in. You can clear these any time by clearing this site's data in your browser. We don't use advertising or tracking cookies.
6. Children
Bas Bolo can be used on school trips run by a teacher or guardian. We don't ask children for anything beyond a display name and a language, and we don't knowingly keep personal data about children.
7. Your rights
Under India's Digital Personal Data Protection Act, 2023 you can ask us to access, correct or delete personal data we hold about you (for guides: the sign-in record and tour metadata), and you can withdraw consent. Write to us at the address below and we will reply within 30 days.
8. Security
All traffic uses HTTPS. Our partner API keys live only on our server and never reach your browser. No system is perfectly secure, so please don't share secrets (passwords, ID numbers, card numbers) out loud in a tour.
9. Changes
If we change this policy we will update the date above, and for important changes we will show a notice in the app.
