Terms of Service

Last updated August 20, 2026

These Terms of Service ("Terms") are a legal agreement between you and Afnan Haq, doing business as Kahini ("Kahini," "we," "us," or "our"), governing your access to and use of the Kahini iOS application and related services (the "Services"). By downloading, accessing, or using Kahini, you agree to these Terms. If you do not agree, do not use the Services.

1. Eligibility

Kahini is intended for adults aged 18 and over, and for younger learners using the Services with the involvement of a parent or legal guardian.

If you are under 18, you may use the Services only with the consent and supervision of a parent or legal guardian. In that case, the parent or legal guardian must be the person who creates and holds the account, accepts these Terms on the minor's behalf, and remains responsible for all activity under that account — including any subscription purchased through it and any charges incurred.

Children under 13 may use the Services only through a parent or guardian's account and under that adult's supervision. We do not knowingly permit anyone under 13 to create their own account or to provide personal information to us directly. If we learn that a child under 13 has created an account without a parent or guardian, we will deactivate it and delete the associated data.

By using Kahini, you represent that you meet these requirements, and — if you are accepting these Terms on behalf of a minor — that you have the authority to do so and agree to be bound by them yourself.

2. Your Account

You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account. Notify us promptly at afnan@kahini.app if you suspect unauthorized use. You agree to provide accurate registration information and to keep it up to date.

3. Subscriptions

Kahini offers auto-renewable subscriptions that unlock lesson content, phrase library access, and other premium features, purchased through the Apple App Store. The specific subscription options, lengths (e.g. monthly, annual), and prices available to you are displayed on the in-app paywall at the time of purchase, and pricing may vary by promotion, region, or introductory offer.

By purchasing a subscription, you acknowledge and agree that:

• Payment will be charged to your Apple ID account at confirmation of purchase.
• Your subscription automatically renews for the same length and at the price shown at purchase (unless changed with notice as permitted by law), unless auto-renewal is turned off at least 24 hours before the end of the current period.
• Your account will be charged for renewal within 24 hours prior to the end of the current period.
• You can manage or cancel your subscription at any time by going to Settings → [your name] → Subscriptions on your iOS device, or via the "Manage Subscription" option in the Kahini app, which links to the same place.
• Any unused portion of a free trial period, where offered, is forfeited when you purchase a subscription during that trial.
• Refunds are handled by Apple in accordance with Apple's own refund policies. We do not process refunds directly and cannot guarantee any particular outcome from an Apple refund request.

Your purchase and use of subscriptions is also governed by Apple's Licensed Application End User License Agreement and the Apple Media Services Terms and Conditions, which apply in addition to these Terms.

4. License to Use the App

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download and use Kahini on Apple-branded devices you own or control, for your personal, non-commercial use, in accordance with Apple's usage rules. See Section 15 for additional Apple-required license terms.

5. Content and Intellectual Property

All lessons, phrases, audio recordings, illustrations, cultural context material, trademarks, and other content made available through Kahini ("Content") are owned by us or our licensors and are protected by copyright, trademark, and other intellectual property laws. Your subscription grants you a personal right to access Content within the app — it does not transfer any ownership rights.

You agree not to copy, download outside the app, redistribute, publicly perform, reverse engineer, scrape, or create derivative works from the Content or the app itself, except as expressly permitted by these Terms or applicable law.

6. Voice Recordings and Speaking Exercises

Kahini's speaking exercises use your device's microphone to record a short audio clip of you saying a Bangla phrase. Recording happens only while a speaking exercise is active, and you can deny or revoke microphone access at any time in iOS Settings — speaking exercises will not function without it, but the rest of the app will.

Each recording is handled as follows:

• The clip is written to your device's temporary storage while the exercise is running.
• It is transmitted to ElevenLabs, our speech-to-text provider, which transcribes it and returns text.
• The transcript is compared against the expected phrase to produce a score of correct, partial, or incorrect.
• The clip is 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 transcript is saved to your account — only the exercise result is recorded as part of your learning progress. ElevenLabs' handling of the clip while it processes the transcription is governed by ElevenLabs' own terms and privacy policy.

We claim no ownership of and no rights in your recordings. A recording is not content you submit to or publish on the Services — it exists only for as long as it takes to score one attempt, and it is never visible to other users. By starting a speaking exercise, you permit us to transmit that recording to ElevenLabs for transcription for that single purpose. We will not use it for anything else.

Pronunciation scoring is automated and approximate. It may misjudge a correct pronunciation or accept an incorrect one, particularly in the presence of background noise, accents, or regional variation. It is a practice aid, not an assessment of your ability or fluency.

7. Notifications and Communications

If you grant permission, Kahini may send you push notifications, such as reminders to keep up your learning streak. You can turn these off at any time in the app's notification settings or in iOS Settings. We may also send you service-related messages about your account, your subscription, security, or changes to these Terms; these are not marketing messages and you cannot opt out of them while you hold an account.

8. Acceptable Use

You agree not to:

• Use the Services for any unlawful purpose or in violation of these Terms.
• Attempt to gain unauthorized access to our systems, other users' accounts, or non-public areas of the Services.
• Interfere with or disrupt the integrity or performance of the Services.
• Circumvent subscription or content-access restrictions.
• Use automated means (bots, scrapers) to access the Services without our prior written consent.

We may suspend or terminate your access to the Services if we reasonably believe you have violated these Terms.

9. Third-Party Services

Some parts of Kahini involve services you interact with directly, and your use of those services is governed by their own terms in addition to these Terms:

• Apple — app distribution, billing, and subscription management, and, if you choose it, Sign in with Apple.
• Google — Sign in with Google, if you choose to sign in that way.

We also rely on infrastructure providers to run the Services behind the scenes. You do not enter into any agreement with them, but they process data on our behalf — including ElevenLabs for speech-to-text transcription (see Section 6), Superwall for paywall and subscription entitlement infrastructure, and Supabase for hosting, authentication, and data storage.

We do not control any of these providers and are not responsible for their acts, omissions, or availability. Our Privacy Policy describes what information each of them handles and why, and is the authoritative and current list.

10. Disclaimers

The Services are provided "as is" and "as available," without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Services will be uninterrupted, error-free, or that any particular learning outcome will be achieved.

11. Limitation of Liability

To the fullest extent permitted by law, Kahini and its owner will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, revenue, or goodwill, arising from your use of the Services.

Our total aggregate liability for all claims arising from these Terms or the Services will not exceed the greater of (a) the total amount paid for the Services attributable to your account in the twelve (12) months preceding the event giving rise to the claim, or (b) fifty U.S. dollars (US$50). You acknowledge that subscription payments are made to Apple rather than directly to us; amounts you paid to Apple for a Kahini subscription count toward this cap.

Some jurisdictions do not allow the exclusion of implied warranties or the limitation or exclusion of liability for certain damages. In those jurisdictions, Sections 10 and 11 apply only to the maximum extent permitted by law, and nothing in these Terms limits or excludes any non-waivable statutory rights you have as a consumer.

12. Indemnification

You agree to indemnify and hold us harmless from any claims, damages, liabilities, and expenses (including reasonable attorneys' fees) arising from your violation of these Terms or misuse of the Services.

13. Termination

You may stop using the Services and delete your account at any time from within the app or by contacting us. We may suspend or terminate your access to the Services if you violate these Terms or if we discontinue the Services. Termination does not entitle you to a refund for any subscription period already paid for; subscription cancellation and refunds are handled through Apple as described in Section 3.

14. Changes to the Services or These Terms

We may modify or discontinue features of the Services at any time. We may also update these Terms from time to time; the "Last updated" date above will reflect the most recent revision. Material changes will be communicated through the app or by other reasonable means. Continued use of the Services after changes take effect constitutes acceptance of the revised Terms.

15. Apple-Required Terms

This section applies because you obtained Kahini through the Apple App Store, and applies in addition to the rest of these Terms. To the extent anything elsewhere in these Terms conflicts with this section as it concerns Apple Inc. ("Apple"), this section controls.

(a) Acknowledgment. These Terms are concluded between you and Kahini only, and not with Apple. Kahini, not Apple, is solely responsible for the app and its content.

(b) Scope of License. The license granted to you in Section 4 is a limited, non-transferable license to use Kahini on any Apple-branded device that you own or control, and as permitted by the Usage Rules set out in the Apple Media Services Terms and Conditions, except that Kahini may be accessed by other accounts associated with you via Family Sharing or volume purchasing.

(c) Maintenance and Support. Kahini is solely responsible for providing any maintenance and support services for the app, as specified in these Terms or as required by applicable law. Apple has no obligation whatsoever to furnish any maintenance or support services with respect to the app.

(d) Warranty. Kahini is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of any failure of the app to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) of the app to you. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the app, and any other claims, losses, liabilities, damages, costs, or expenses attributable to any failure to conform to any warranty will be Kahini's sole responsibility.

(e) Product Claims. Kahini, not Apple, is responsible for addressing any claims by you or any third party relating to the app or your possession and use of it, including but not limited to: (i) product liability claims; (ii) any claim that the app fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy, or similar legislation.

(f) Intellectual Property Claims. In the event of any third-party claim that the app or your possession and use of the app infringes that third party's intellectual property rights, Kahini, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of any such intellectual property infringement claim.

(g) Legal Compliance. You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.

(h) Third-Party Terms. You must comply with any applicable third-party terms of agreement when using the app.

(i) Third-Party Beneficiary. You acknowledge and agree that Apple, and Apple's subsidiaries, are third-party beneficiaries of these Terms, and that upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary of these Terms.

(j) Developer Contact. Any questions, complaints, or claims with respect to the app should be directed to Kahini using the contact details in Section 18.

16. Governing Law and Dispute Resolution

These Terms are governed by the laws of the State of New York, United States, without regard to its conflict-of-laws principles, except where superseded by Apple's own terms governing App Store transactions.

You and we agree that the state and federal courts located in New York County, New York will have exclusive jurisdiction over any dispute arising out of or relating to these Terms or the Services, and each party consents to personal jurisdiction and venue in those courts.

If you are a consumer resident in the European Union, the United Kingdom, or another jurisdiction whose law gives you the right to bring proceedings in your local courts or to rely on mandatory local consumer protections, nothing in this section removes that right.

17. General Provisions

Severability. If any provision of these Terms is held invalid, illegal, or unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, or severed if modification is not possible. The remaining provisions will continue in full force and effect.

Entire Agreement. These Terms, together with our Privacy Policy and any additional terms presented to you in the app, constitute the entire agreement between you and us regarding the Services, and supersede any prior agreements or understandings on that subject.

No Waiver. Our failure to enforce any provision of these Terms is not a waiver of that provision or of any other. A waiver is effective only if made in writing by us.

Assignment. You may not assign or transfer these Terms or any rights under them without our prior written consent, and any attempt to do so is void. We may assign these Terms without restriction, including in connection with a merger, acquisition, reorganization, or sale of assets.

Survival. Sections 5 (Content and Intellectual Property), 10 (Disclaimers), 11 (Limitation of Liability), 12 (Indemnification), 13 (Termination), 15 (Apple-Required Terms), 16 (Governing Law and Dispute Resolution), and 17 (General Provisions) survive any termination or expiration of these Terms.

Notices. We may provide notices to you through the app, by email to the address associated with your account, or by posting to kahini.app. You may send notices to us at afnan@kahini.app or at the postal address in Section 18.

Force Majeure. We are not liable for any delay or failure to perform caused by events beyond our reasonable control, including acts of God, natural disasters, war, terrorism, labor disputes, government action, network or power failures, or failures of third-party providers.

Feedback. If you send us suggestions, ideas, or feedback about the Services, you grant us a perpetual, irrevocable, royalty-free, worldwide license to use and incorporate them without any obligation or compensation to you. We will not treat feedback as confidential.

Headings. Section headings are for convenience only and do not affect the interpretation of these Terms.
