Learn English (영어배우기) Privacy Policy
Haru Studio operates Learn English (영어배우기). This policy covers the app's learning, account, social, notification and subscription features.
Privacy contact: english.learning.mobile@gmail.com.
Information we use
| When you use a feature | Information processed | Why we use it |
|---|---|---|
| Learn and adjust the app | Chosen language, course, topics and levels; learning goals and written motivation; saved words, answers, quiz results, progress, points and learning times | Provide learning, select subsequent practice and show progress |
| Create or sign in to an account | Email address, account identifier, nickname, authentication credentials or the sign-in provider's authentication result | Sign you in, protect your account and synchronise your information |
| Set a profile or use friends | Profile image or avatar, friend code, requests and relationships, shared learning progress and challenge results | Display your profile, find friends and provide shared learning features |
| Receive notifications | Notification choices, delivery token, installation identifier, platform and language | Schedule learning reminders and deliver supported account or friend notifications |
| Use the app | A persistent installation identifier, selected onboarding options including age band, screen and feature events, quiz and social outcomes, event times, app version, platform, language and course | Understand how the app is used, improve learning flows and investigate faults |
| Send feedback | Your message, report type, installation identifier, device model and OS, app/build/update information, language, time and signed-in status; your email if you ask for a reply | Investigate the report, prevent abusive submissions and reply when requested |
| Purchase or restore a subscription | App or anonymous customer identifier, store product and transaction information, purchase history and subscription status | Verify access, restore purchases and understand subscription operation |
| Request guardian consent | Child's age group and country or region; guardian email and authenticated identifier; request and verification references, decision, times and notice version | Verify an adult, record separate guardian consent and manage the enrolled learner's access |
Learning data and settings are stored on your device. Signing in enables account-related data to be sent to our backend and synchronised. Using the app without an account does not mean that no information leaves the device: installation analytics, update requests and any feedback you send can still involve our service providers.
Usage analytics can use an authenticated account or a separate guest or installation identity. Our server no longer uses account-link events to assign an installation's earlier activity to an account. Earlier guest and installation records can remain separate. Analytics events do not include the nickname or interest text you type into onboarding; they record whether those fields were completed. Your written learning motivation and profile information have separate learning and account functions and may be synchronised when signed in.
Technical server logs can include request paths, status, user agent and account identifiers carried in requests. Infrastructure providers also process IP addresses and may derive approximate city or country information for network operation and security. The app does not request GPS location for these features. We do not receive your full payment-card details from an App Store or Google Play purchase.
What other learners can see
Your nickname and profile image or avatar can appear in friend discovery and social features. Friends can see the learning information those features share, such as goals, progress and challenge results. Your friend code lets another learner find your profile.
Uploaded profile photos are not a private photo vault. Other signed-in users may be able to access them, so choose a photo you are comfortable showing to others. Passwords and payment-card details are not displayed in friend features.
Service providers and international processing
| Provider | Role |
|---|---|
| Supabase | Account authentication, database and file storage, learning/social synchronisation, analytics, feedback and notification-device records |
| RevenueCat | Subscription identification, purchase verification and restoration, and subscription reporting |
| Apple App Store and Google Play | Store purchases, renewals, cancellation and refunds |
| Apple and Google sign-in | Authentication when you choose a supported sign-in method |
| Expo | App-update delivery and push-notification infrastructure |
| Google Gmail | Configured authentication-email delivery and our support inbox |
| KWS (Epic Games) | Adult verification for guardian consent; receives the guardian email, child's country or region, language and request reference |
Each provider receives information relevant to its role. We do not send your profile photos or quiz answers to RevenueCat as subscription attributes. Service providers and stores process information under their applicable terms and privacy practices. Our Supabase database is hosted in Tokyo, Japan. Provider operations, support and infrastructure can involve processing outside your country; the database's location does not describe every provider's processing location.
We do not sell your personal information or use this app's data for targeted advertising.
Retention
Account and synchronised learning/social information is kept to operate your account and features. Account deletion and other removal requests are described below. Your device's local learning data and initial-access record have a separate lifecycle from the server account; signing out or deleting the account does not automatically clear them.
Detailed usage records and technical diagnostics are retained for product analysis and fault investigation, separately from your learning history. Grouped usage totals can be kept for longer term analysis; those totals do not contain individual account identifiers. You can ask us to include installation-linked usage records when you request deletion.
Account deletion removes feedback linked to that verified account. Unlinked feedback and support correspondence can remain; ask us to include those records when requesting deletion. We do not promise an automatic expiry date for all support records.
The guardian process uses separate learner, guest and guardian authentication identities. Deleting a linked learner account removes its consent records but does not automatically delete the guardian's email sign-in account or a surviving guest identity. That guest retains only its own identifier and declared age group as age history, without the former account, guardian email or verification proof. This prevents the same identity bypassing an earlier under-14 declaration; the history is deleted when that guest identity is deleted. Include these separate identities in a deletion request when relevant. A guardian request's 24-hour approval deadline is not a deletion deadline.
Database backups rotate separately from live records, and deleted information can remain in existing backup copies until those copies expire. Photo files, technical logs, store transaction records and provider records have separate retention arrangements. We will explain any applicable retention or limits when handling your request rather than promise that every copy is immediately erased.
Account and data deletion
You can request deletion in the app's account screen. You can also request account or other personal data deletion without reinstalling the app by emailing english.learning.mobile@gmail.com. Identify the app as Learn English (영어배우기) and tell us the account email and records you want removed. If you used the app without an account, describe the relevant feedback or other interaction so we can help locate it. Do not send passwords or full payment-card numbers.
We may need to verify that the request concerns your information or that you are authorised to act for the learner. You can also ask to access or correct information, withdraw consent where applicable, or ask us to stop particular processing. We will explain the outcome and any reason some records must remain.
Deleting the app account removes its server profile, synchronised learning and social records, analytics recorded under that authenticated account, and feedback linked to that verified reporter. It also requests deletion of the associated RevenueCat customer record; provider processing may finish later. Earlier guest or installation records are not automatically treated as belonging to the account. Unlinked feedback, support correspondence, device data, backups and store records may need separate handling. Tell us if your request includes those records.
Account deletion, app removal and signing out do not cancel a store subscription. Cancel recurring billing through the store account used for the purchase. A deletion request is not a refund request.
Your choices and children's information
You choose whether to create an account, upload a photo, use friend features, send feedback or ask for a reply. You can change notification choices in the app and notification permission in device settings. Refusing an optional feature limits that feature; it does not itself cancel a subscription.
Learners under 14 must have consent from a parent or legal guardian before using the app. Guardian consent to information processing is separate from authorising a paid subscription. A parent or legal guardian can contact us to ask about a child's information, request its deletion or withdraw consent. We may need to verify the requester's authority. A child's own checkbox or a store's family-payment setting is not a substitute for the required guardian process.
Security and changes
We use encrypted connections for data sent between the app and our production services, together with access controls for stored information. No transmission or storage system can be guaranteed completely secure.
We will keep the current policy on this page. Material changes and any additional consent needed for new processing will be communicated through an appropriate notice. Contact Haru Studio at english.learning.mobile@gmail.com with privacy questions.
