Kahini .Kahini is a Bangla language learning iOS app built specifically for diaspora families and intercultural couples — not a generic language app. Every lesson is grounded in real family situations: Eid gatherings, weddings, meeting the in-laws. Lessons combine cultural nuance, native speaker audio, and speaking exercises so learners don't just pick up vocabulary — they learn how Bangla actually sounds and feels in context.
- Engage with us in other related ways, including any marketing or events

1. WHAT INFORMATION DO WE COLLECT?
Personal information you disclose to us
In Short: We collect personal information that you provide to us.We collect personal information that you voluntarily provide to us when you
Personal Information Provided by You. The personal information that we collect depends on the context of your interactions with us and the Services, the choices you make, and the products and features you use. The personal information we collect may include the following:
- names
- email addresses
- usernames
- passwords
- learning progress, lesson results, and streak history
- device push notification tokens, if you enable notifications
Sensitive Information. We do not process sensitive information.
Payment Data. Subscriptions are sold and processed by Apple, not by us. We never receive or store your card number, security code, or any other payment instrument details — all payment data is handled and stored by Apple. We receive only the resulting subscription status for your account (for example, whether a subscription is active and when it renews or expires). You may find their privacy notice link(s) here: https://www.apple.com/legal/privacy/.
Social Media Login Data. We may provide you with the option to register with us using your existing social media account details, such as Sign in with Apple or Sign in with Google. If you choose to register in this way, we will collect certain profile information about you from the social media provider, as described in the section called HOW DO WE HANDLE YOUR SOCIAL LOGINS? below.
Application Data. If you use our application(s), we also may collect the following information if you choose to provide us with access or permission:
- Mobile Device Access. We may request access or permission to certain features from your mobile device, including your mobile device's microphone, notifications, and storage. If you wish to change our access or permissions, you may do so in your device's settings.
- Voice Recordings. Kahini's speaking exercises record a short audio clip of you saying a Bangla phrase. The clip is written to your device's temporary storage, transmitted to our speech-to-text provider ElevenLabs for transcription, and then deleted from your device. We do not store your voice recordings on our servers, and we do not use them to train any speech or language model. Neither the audio nor the resulting transcript is saved to your account — only the exercise result (correct, partial, or incorrect) is recorded as part of your learning progress. ElevenLabs' handling of the clip during transcription is governed by ElevenLabs' own privacy policy. Recording happens only while a speaking exercise is active, and you can revoke microphone access at any time in your device settings.
This information is primarily needed to maintain the security and operation of our application(s), for troubleshooting, and for our internal analytics and reporting purposes.
All personal information that you provide to us must be true, complete, and accurate, and you must notify us of any changes to such personal information.
Information automatically collected
In Short: Some information — such as your Internet Protocol (IP) address and/or browser and device characteristics — is collected automatically when you visit our Services.We automatically collect certain information when you visit, use, or navigate the Services. This information does not reveal your specific identity (like your name or contact information) but may include device and usage information, such as your IP address, browser and device characteristics, operating system, language preferences, referring URLs, device name, country, location, information about how and when you use our Services, and other technical information. This information is primarily needed to maintain the security and operation of our Services, and for our internal analytics and reporting purposes.
The information we collect includes:
- Log and Usage Data. Log and usage data is service-related, diagnostic, usage, and performance information our servers automatically collect when you access or use our Services and which we record in log files. Depending on how you interact with us, this log data may include your IP address, device information, browser type, and settings and information about your activity in the Services (such as the date/time stamps associated with your usage, pages and files viewed, searches, and other actions you take such as which features you use), device event information (such as system activity, error reports (sometimes called "crash dumps"), and hardware settings).
- Device Data. We collect device data such as information about your computer, phone, tablet, or other device you use to access the Services. Depending on the device used, this device data may include information such as your IP address (or proxy server), device and application identification numbers, location, browser type, hardware model, Internet service provider and/or mobile carrier, operating system, and system configuration information.
- In-App Analytics, Error Reports, and Session Replays. When you use the Kahini iOS app, we use PostHog to automatically collect (i) usage events, such as lessons started and completed, paywall views, and account creation; (ii) crash and error reports; and (iii) session replays, which are periodic screenshots of the app screens you interact with, together with your taps and navigation. Any text you type into a text field is masked before capture and never leaves your device. These records are associated with a random device identifier and, once you sign in, with your Kahini user ID. We do not send your name or email address to PostHog. Session replay is a core part of how we find and fix bugs and cannot be disabled separately from using the app.

- To diagnose and fix problems. We review crash reports, error logs, and session replays to understand what went wrong when the app misbehaves and to improve the app's design.
- To provide speaking-exercise feedback. We transmit speaking-exercise audio to our speech-to-text provider so we can transcribe it and return a pronunciation score to you. The audio is not stored, as described above.
- To manage your subscription. We process subscription status received from Apple to determine what content your account can access.
- To send you notifications. If you enable them, we process your device push token to send reminders, such as streak reminders. You can turn these off at any time.
- To save or protect an individual's vital interest. We may process your information when necessary to save or protect an individual's vital interest, such as to prevent harm.
3. WHAT LEGAL BASES DO WE RELY ON TO PROCESS YOUR INFORMATION?
In Short: We only process your personal information when we believe it is necessary and we have a valid legal reason (i.e., legal basis) to do so under applicable law, like with your consent, to comply with laws, to provide you with services to enter into or fulfill our contractual obligations, to protect your rights, or to fulfill our legitimate business interests.If you are located in the EU or UK, this section applies to you.
The General Data Protection Regulation (GDPR) and UK GDPR require us to explain the valid legal bases we rely on in order to process your personal information. As such, we may rely on the following legal bases to process your personal information:
- Consent. We may process your information if you have given us permission (i.e., consent) to use your personal information for a specific purpose. You can withdraw your consent at any time. Learn more about withdrawing your consent.
- Performance of a Contract. We may process your personal information when we believe it is necessary to fulfill our contractual obligations to you, including providing our Services or at your request prior to entering into a contract with you.
- Legitimate Interests. We may process your information when we believe it is reasonably necessary to achieve our legitimate business interests and those interests do not outweigh your interests and fundamental rights and freedoms. For example, we may process your personal information to analyze how our Services are used so we can improve them to engage and retain users, and to understand how our users use our products and services so we can improve user experience.
- Legal Obligations. We may process your information where we believe it is necessary for compliance with our legal obligations, such as to cooperate with a law enforcement body or regulatory agency, exercise or defend our legal rights, or disclose your information as evidence in litigation in which we are involved.
- Vital Interests. We may process your information where we believe it is necessary to protect your vital interests or the vital interests of a third party, such as situations involving potential threats to the safety of any person.
If you are located in Canada, this section applies to you.

Our Services offer you the ability to register and log in using a third-party account — specifically Sign in with Apple or Sign in with Google. Where you choose to do this, we receive limited profile information from that provider, typically your name and email address. If you use Sign in with Apple and choose to hide your email, Apple provides us with a private relay address instead of your real one. We do not receive your contacts, friends list, or any other information from these providers.
We will use the information we receive only for the purposes that are described in this Privacy Notice or that are otherwise made clear to you on the relevant Services. Please note that we do not control, and are not responsible for, other uses of your personal information by your third-party social media provider. We recommend that you review their privacy notice to understand how they collect, use, and share your personal information, and how you can set your privacy preferences on their sites and apps.

Session replays and error reports collected through PostHog are automatically deleted 30 days after they are captured. Analytics events are kept for as long as you have an account with us and are deleted on request.

7. HOW DO WE KEEP YOUR INFORMATION SAFE?
In Short: We aim to protect your personal information through a system of organizational and technical security measures.We have implemented appropriate and reasonable technical and organizational security measures designed to protect the security of any personal information we process. However, despite our safeguards and efforts to secure your information, no electronic transmission over the Internet or information storage technology can be guaranteed to be 100% secure, so we cannot promise or guarantee that hackers, cybercriminals, or other unauthorized third parties will not be able to defeat our security and improperly collect, access, steal, or modify your information. Although we will do our best to protect your personal information, transmission of personal information to and from our Services is at your own risk.

10. CONTROLS FOR DO-NOT-TRACK FEATURES
Most web browsers and some mobile operating systems and mobile applications include a Do-Not-Track ("DNT") feature or setting you can activate to signal your privacy preference not to have data about your online browsing activities monitored and collected. At this stage, no uniform technology standard for recognizing and implementing DNT signals has been finalized. As such, we do not currently respond to DNT browser signals or any other mechanism that automatically communicates your choice not to be tracked online. If a standard for online tracking is adopted that we must follow in the future, we will inform you about that practice in a revised version of this Privacy Notice.California law requires us to let you know how we respond to web browser DNT signals. Because there currently is not an industry or legal standard for recognizing or honoring DNT signals, we do not respond to them at this time.
