Last updated: 11 November 2026 · Applies to the BolSetu app for Android and iOS.
BolSetu is a spoken-English and interview-practice app. The short version: your lessons and progress stay on your phone, there are no user accounts, and we do not store your practice answers.
BolSetu is operated by BolSetu Technologies Private Limited, Mumbai, India. For any privacy question or request, contact support@bolsetu.com. Under India's Digital Personal Data Protection Act, 2023, this is also our grievance contact.
| Data | Where it goes | Kept? |
|---|---|---|
| Lesson progress, XP, streak, goal and language choice | Stored only on your phone | Until you uninstall or tap "Reset my progress" |
| Your speech, when you tap the microphone | Turned into text by your phone's own speech service (Apple or Google) | Not kept by us — we never receive or store audio |
| Your interview answer, only when you tap "Get AI feedback" | Sent to our server and on to Anthropic's Claude API to generate feedback | Not stored — used to produce your feedback, then discarded |
Tapping the microphone uses your phone's built-in speech recognition — normally Google on Android and Apple on iOS. Depending on your device settings that processing may happen on the device or on their servers, under Google's or Apple's privacy policies, not ours.
AI feedback is optional and runs only when you tap "Get AI feedback". That request sends the interview question and your answer to our server, which forwards it to Anthropic. Our server keeps no copy and no log. If you never tap that button, nothing you write or say leaves your phone.
Because everything we hold sits on your own device, you control it directly: tap "Reset my progress" in the app to erase it, or uninstall to remove it entirely. There is no server-side account for us to delete. If you believe we hold personal data about you and want it corrected or erased, write to support@bolsetu.com and we will respond within 30 days.
BolSetu is intended for users aged 18 and over and is not directed at children. We do not knowingly collect data from anyone under 18.
All network requests use HTTPS. Our AI feedback server stores nothing, so there is no database of your answers that could be breached.
If this policy changes we will update this page and the date above. If a future version of the app adds sign-in, payments, analytics or ads, this policy will be updated before that version is released.
