AI EIKAIGA (hereinafter referred to as "the App") places the highest priority on privacy protection so that all users can use our services with peace of mind.
The App obtains user voice data (spoken content) via the device's microphone in order to provide speech recognition in English conversation and convenient learning features, such as replaying audio during conversations.
The acquired voice data is sent to the server for real-time processing using secure, encrypted communications (WebRTC/WebSocket) and is temporarily held in the server's memory (temporary buffer), but is discarded immediately after the conversation ends. Voice data is never permanently stored as files on our servers or external services, nor is it ever used as training data for AI models.
By system design, it is structured securely and closed such that no third party, nor even the server administrator, can reconstruct and listen to the user's actual voice afterwards, so you can use it with complete peace of mind.
To provide the highest quality learning experience, the App uses the following third-party services. Data sent to these services is used solely for the purpose of providing the App's features.
[Important] Usage of Data for AI Model Training:
The App uses APIs that adhere to strict enterprise privacy standards (Google Cloud Vertex AI API and OpenAI API) for generating AI responses. Your conversation data and inputs are never reused for training the AI models of the respective providers, so you can use the service with peace of mind.
The English conversation rooms in the App are designed as completely independent private spaces accessible by only one user per room.
There are no social features such as matching with other users, chat, or voice calls. Therefore, risks such as troubles with unknown third parties online or personal information leaks cannot structurally occur, providing an environment where children and students can safely focus on learning.
The App uses "Keychain" and "iCloud Key-Value Store (KVS)," which are robust security features provided by Apple, to safely store users' remaining point balances and certain configuration data, and to enable seamless transfer when changing devices.
These data are encrypted, stored, and synchronized only within the user's own device and in the secure iCloud area linked to the user's Apple ID. All synchronized data is managed according to Apple's security standards, and we (the operator) never identify or acquire your personal information (such as Apple ID, name, email address, etc.) or data. Please note that if you delete the app or initialize your device in an environment where iCloud is not enabled, your data such as point balances will be lost and cannot be recovered.
[Security Management Regarding Point Transfers]
For secure data protection and duplicate prevention purposes, the history of point transfers between devices (device identification flag) is encrypted and permanently retained in Keychain and iCloud. Therefore, please note that a device that has once performed a point transfer (migration) cannot perform further transfers to or from other devices.
The "4-digit PIN code" issued in the feature for linking two devices is randomly generated by the system and stored temporarily (for a maximum of 10 minutes) on the Firebase database. This data is automatically and completely deleted upon completion of linking or disconnection, and is never linked to any personal information.
The App can be used completely anonymously, and we do not collect or require any personal information such as your name, email address, or phone number.
The App provides in-app purchase features (point purchases). All payments are processed securely through Apple Inc. (App Store) systems.
We (the operator) never directly obtain, store, or view your financial or payment information, such as credit card numbers. The management of purchase history, refund processing, and other related data is governed by Apple's Privacy Policy and Terms of Service.
The App anonymously collects the following information in order to maintain free service provision and to improve future functionality and quality. This information does not identify individuals.
[Usage Data Collected (Analytics) and Error Logs]
We collect app operation history (timing of conversation start, selected age group, gender, level, situation, number of conversation turns, error occurrences, etc.) as statistical data. In addition, if the app terminates unexpectedly, anonymous error logs (device model, OS version, etc.) may be collected for bug fixes.
* As described in Section 1, please be assured that voice data and actual conversation content (text) are never included in these statistical data.
[Ad Delivery and Child Protection]
As an option to allow users to use the service for free, the App delivers advertisements via Google AdMob (video ads when recharging points for free). If you purchase points via in-app purchase, you can use all features without viewing any ads.
To ensure safe use even for young children, the system automatically restricts ads according to the selected "Age Group." Specifically, when an age group corresponding to under 13 is selected, a safeguard is in place to stop personalized ad delivery and only display safe ads suitable for all ages.
On iOS devices, when viewing a video ad for the first time to recharge points for free, a confirmation prompt (App Tracking Transparency) asking "Allow Tracking Across Other Companies' Apps and Websites?" may be displayed. If permission is granted, personalized ads matching the user's interests will be more easily served.
Even if you choose not to allow tracking, you can continue to use all features of the App without restriction. You can change this setting at any time from your device's "Settings" app.
The App accesses device storage (photo album, Files app, etc.) only when you use the following features:
.enroom)These accesses are executed only at the moment you perform save or file selection operations. Please rest assured that the App will never read existing photos or unrelated files on your device or transmit them externally without permission.
The App provides a feature that allows users to enter custom text (prompts) and use generative AI to create original "English Conversation Levels," "Situations," and "Gamebooks."
[Storage and Use of Input Text]
The text (prompts) entered by the user in this feature is only sent via encrypted communication to the AI service (Google Cloud Vertex AI, etc.) to generate original configuration data, and is never stored on the server after generation is completed.
In addition, for convenience (input history feature), a history of up to 10 previously entered texts is automatically stored only on the user's own device (local storage), and this history data is never sent to or collected by our servers.
As stated in Section 2, input content is never reused for training external AI models, so you can enter text freely and with peace of mind.
[Data Backup and Encrypted Sharing Feature]
Created custom data can be exported and shared externally (to other devices or third parties) as the App's proprietary encrypted file (.enroom) through user operations. Because files are exported completely encrypted on the device using Apple's standard security framework (CryptoKit), it is designed securely to prevent the risk of input text (prompts) being viewed or tampered with by third parties during transmission or sharing.
[Safety Standards (Safety Features) and Intellectual Property Protection]
Input text is automatically filtered based on strict safety standards and compliance. If an input violates our standards, such as promoting crime, violence, discrimination, or other content contrary to public order and morals, generation will be blocked.
Furthermore, if an input that risks infringing on third-party intellectual property rights (copyrights, trademark rights, etc.), such as real game, anime, or movie titles or character names, is entered, the system includes a safeguard that uses AI to automatically and significantly abstract/convert (modify) the output into a generic worldview or original setting. This prevents the risk of unintentionally generating content closely resembling existing IP.
[Disclaimer]
Custom situations, gamebooks, conversation contents, and images generated in the App are created by AI, and we do not guarantee the complete accuracy, legality, or suitability for a particular purpose of the content.
Users must not input or use prompts for the purpose of infringing third-party intellectual property rights or reputation, or for purposes contrary to public order and morals. In addition, while we provide automatic modification features based on the safety standards mentioned above, the operator does not guarantee the complete absence of rights infringement in the generated results. In the event that trouble or damages arise with a third party resulting from the user's input content, the user shall resolve it at their own responsibility, and the operator assumes no liability whatsoever.
When this policy is revised, users will be clearly notified through a prompt requesting re-consent upon launching the app.
