Effective date: September 20, 2026
This Privacy Policy explains how Kaindra Rizq Sachio ("we", "us", or "our") collects, uses, shares, and retains information when you use the Langpush - AI Language Tutor mobile application (the "Application").
The categories of information and the ways we process it may depend on how you use the Application, the features you choose, and the app build available to you.
We may collect information directly from you, automatically from your use of the Application and device, and from service providers when you choose sign-in, subscription, support, or other connected features.
The information we collect depends on how you interact with the Application, the features you use, and the settings available in your app build.
If you use a third-party sign-in option, we may receive the account information you authorize through that provider, subject to its settings and policies.
When you choose to use voice features, the Application may process microphone audio, transcripts, and speech or pronunciation feedback. Voice and AI features may use third-party AI, speech, translation, or pronunciation service providers. The providers used may vary depending on the feature, platform, region, or app build.
Transcripts may be stored with the related conversation. Short audio clips may be stored temporarily on your device for replay. We do not use voice features to display advertising. Please do not use voice features to share sensitive information that you do not want processed by these providers.
Some builds may use product analytics or limited replay with masking controls. These features may be disabled or configured differently depending on the build you use.
The Application may store session information, preferences, learning settings, grammar drafts, and temporary audio replay files on your device. These files may be removed by the Application, your device, or when the Application is uninstalled.
We use information for the following purposes:
We may share information with service providers that help us provide, secure, analyze, and support the Application. These providers may process information on our behalf and only as needed for the services they provide. We require service providers to protect information in a manner consistent with this Privacy Policy and applicable law. The categories of providers may include:
When support chat is enabled and you choose to use it, Crisp may process your account identifier and information you provide in the chat, such as your name, email address, profile image, subscription status, and support message. You can review Crisp's privacy policy.
Provider selection may change over time or vary by feature, platform, region, or app build. Some providers may process information outside your country of residence under their own privacy notices and applicable agreements.
The Application does not display third-party advertisements. In builds where attribution is enabled, AppsFlyer may process device and technical information, app activity, and completed subscription conversion events to measure advertising effectiveness. The Application does not send chat messages or transcripts through AppsFlyer.
On iOS, the Application may request App Tracking Transparency permission during onboarding or after sign-in. AppsFlyer receives the IDFA only if you grant that system permission. You can change this choice in your iOS privacy settings. Declining permission does not prevent you from using the Application, although advertising measurement may be less precise.
We may also disclose information when required by law or legal process, to protect the rights and safety of users or the Application, to investigate fraud or security incidents, or in connection with a merger, acquisition, financing, or transfer of all or part of our business.
We retain account records, conversations, learning activity, and related information for as long as reasonably needed to provide and improve the Application, maintain your account, comply with legal obligations, resolve disputes, and enforce our agreements.
Third-party service providers may retain data they process under their own privacy notices and our applicable agreements with them. Their processing and retention may occur outside your country of residence.
Data stored locally on your device, such as preferences and grammar drafts, remains on your device until it is removed by the Application, overwritten, or cleared through app removal or device/app storage controls.
You can request deletion of your Application account and associated first-party app data directly in the Application:
Account deletion is permanent and cannot be undone. The Application sends the request to our server, which removes the account and associated first-party data linked to it. We aim to remove the Application data associated with the account, subject to information we may need to retain for legal, security, fraud-prevention, or compliance reasons. Data stored locally on your device may remain until you remove the Application or clear its storage.
Deleting your Application account does not necessarily remove information already processed by independent third-party providers, such as support-chat, attribution, subscription, or diagnostic providers. We handle such requests according to the provider's policies, our applicable agreements, and the law. If you need help with account or data deletion, contact us at kaindradev@gmail.com.
Depending on where you live, you may have rights to request access to, correction of, deletion of, or information about the use of your personal information. You may contact us at kaindradev@gmail.com to make a request.
You can manage microphone and App Tracking Transparency permissions through your device settings. Where available, you may also use privacy choices offered by a service provider.
The Application is not directed to children under the age of 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information through the Application, please contact us at kaindradev@gmail.com.
We use technical and organizational measures designed to protect information processed through the Application. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
We may update this Privacy Policy from time to time. We will post the updated version on this page and update the effective date above. Where required, we will provide additional notice of material changes.
