Maho Privacy Policy
Updated: November 9, 2026
Scope and contact
This policy covers the Maho Japanese learning app and learning service provided by Appar Technologies (約沛科技有限公司). The Android package is tw.com.appar.jpreader. Contact hello@appar.com.tw about your data. A separate notice covers marketing website analytics.
Account information
When you sign in with email or Google, we and the authentication provider process your email address, account identifier, and any name or profile image you provide or authorize, to sign you in, manage your account and synchronize data. Passwords are handled by the authentication service. Do not include passwords in learning content or support messages.
Learning features you choose
We process text, photos, images, URLs, webpage or YouTube caption content that you choose to submit, together with AI conversations, analysis results, saved items, notes, learning progress and usage records, to provide analysis, speech playback, AI learning assistance and synchronization. Feedback can include photos or videos you choose to attach. Camera or file selection is used when you request the relevant feature; your entire photo library is not automatically uploaded.
Purchases and credits
Google Play or Apple processes payments. We and RevenueCat process product identifiers, purchase receipts, transaction status, purchase history, account identifiers and credit activity to validate purchases, deliver content, restore purchases and prevent duplicate redemption. We do not receive your full payment card number.
Operation and optional analytics
Requests may include connection, device, app version, language, error and usage information needed to run and protect the service. Native app usage analytics is off by default. Firebase Analytics is enabled only after you turn it on in Settings and can be turned off there. Analytics may include feature interactions, device or app-instance identifiers and approximate region derived from IP addresses. Our custom analytics events do not include emails, AI conversation text or learning text. The app does not display third-party ads or enable analytics advertising personalization.
Account usage journeys and learning feedback
When you sign into the native app, we link screen names, feature interactions, event times, sessions, app version/build, platform and estimated foreground active time to your account to understand new and returning users and improve Maho. Journey events exclude conversation text, learning input, full URLs and payment details. Journey history is enabled by default, while an existing explicit analytics opt-out is respected. Turn off future collection at Settings → Usage journey history. This control is separate from Firebase Analytics, which remains off by default. Detailed events are retained for up to 35 days and daily totals for up to 400 days. We may invite you to share why you are learning Japanese and suggestions during a pause in use, at most once per account per week; you can skip. Answers you submit are linked to your account and kept as needed for product improvement and support. Contact us to request an export or deletion. This data is not used for advertising tracking.
Service providers and international processing
Necessary data is processed by our hosting and database services, Google/Firebase, RevenueCat, and model or speech providers executing the AI analysis or playback you request (for example, OpenRouter, Google Cloud or Microsoft Azure). Processing may take place outside Taiwan. Avoid submitting unnecessary personal or confidential information. Google Play, Apple and third-party websites you open also process data under their own policies.
Retention and deletion
Account and learning data is retained as needed to provide the services and support you use. You may request deletion of your account and associated personal data, or identify particular content to delete. If limited records must be kept for transaction accounting, law, security or fraud prevention, we restrict their purpose and access and explain the applicable reason and retention period when handling the request. Backups are not used for routine service access; any relevant backup or legally required retention arrangements will be explained in our response.
Your choices and security
You may avoid optional features, decline unnecessary permissions, turn off usage analytics, or contact us to access, correct, export or delete your data. Data is encrypted in transit using HTTPS. Account deletion affects saved items, progress, notes and credits and does not automatically request a store refund. Save any content you need before deletion.
Policy updates
We update this page and its date when features or data handling change. Changes that require a new choice will be communicated through an appropriate in-service notice.
