イクラ単語 — Privacy Policy

Article 1 (Purpose)

This Policy sets forth the information handled by the Application, the places in which such information is stored, the extent to which any such information is made available to the Developer or to any third party, and the means available to the User with respect to such information.

Article 2 (Definitions)

In this Policy, the following terms shall have the meanings set forth below:

• (a) "User" means any person who installs or uses the Application;
• (b) "Study Records" means the records the Application keeps of the study of the User, namely the progress and answers of the User for each word, the results of the vocabulary test, the daily records and stamps, the word books the User has chosen, and the settings of the Application;
• (c) "Word Book" means a set of words, meanings, example sentences and audio offered in the Application, whether included in the Application or downloaded; and
• (d) "Usage Data" means the usage statistics concerning the Application that are collected by means of Google Firebase Analytics, as further specified in this Policy.

Article 3 (Information Handled)

The Application does not require or offer a user account, does not ask for the name, email address or any contact information of the User, contains no advertising, and does not track the User across applications or websites.

Study Records are stored on the device of the User and are not transmitted to the Developer. Information leaves the device of the User only in the following cases, each of which is described in this Policy: Usage Data; the download of a Word Book; a content error report the User chooses to send; the backup of the device; an export file the User chooses to create; and, where the Application offers an in-app purchase, the processing of that purchase by the Store.

Article 4 (Usage Statistics)

In order to improve the Application, the Application uses Google Firebase Analytics to collect Usage Data. Usage Data consists of (a) events concerning the use of the Application, namely the start, completion and undoing of the vocabulary test together with its result (the number of questions, the estimated vocabulary size, the estimated level and the time taken); the Word Book and the number of new words per day the User chooses; the start and completion of a day's study with the numbers of new and review words; for each word studied, the identifier of the word, whether the User knew it, needed a hint or did not know it, and the hint used; the answers to spelling and listening practice; the completion of each group of words; the pressing of the daily stamp with the length of the current streak; the export and import of data and their outcome; the outcome of a request for permission to send notifications; and the sending of a content error report together with the identifier of the word concerned; and (b) the information that Google Firebase Analytics records for any application, such as the device model, the operating system version, the version of the Application, the language of the device, an approximate location derived by Google from the network address of the device, the times at which the Application is opened, and any purchase made in the Application.

Usage Data never includes the name or contact information of the User, the text the User writes in a content error report, or the contents of an export file. Usage Data is associated with a randomly generated identifier assigned to the installation of the Application, and not with the name of any User or with any account. The Application does not collect the advertising identifier of the device, does not permit Usage Data to be used for advertising or personalised advertising, and does not register with any advertising network.

The Developer uses Usage Data solely for the purposes of understanding how the Application is used, how well its study method works, and improving it. Usage Data is processed on behalf of the Developer by Google (see Firebase privacy information).

Article 5 (Download of Word Books)

Where the User opens a Word Book that is not included in the Application, the Application downloads that Word Book once from the server of the Developer (ikura.shosin-labs.com), after which it is used without a network connection. The request names only the file requested; as with any request on the internet, the server receives the network address of the device, which is used only to deliver the file and is not combined with Usage Data or with any other information.

Article 6 (Content Error Reports)

Where the User chooses to report an error in the content of a word, or an error of the Application, and taps the button to send it, the Application sends to the server of the Developer (api.shosin-labs.com) the word, Word Book and content version concerned, the kind of error the User chooses, the text the User writes, if any, the version of the Application and of the operating system, and the platform of the device. No name, email address or Study Records are sent, and nothing is sent until the User sends the report. The Developer uses such information solely to correct the content and the Application, and does not share it with any third party.

Article 7 (Access to Functions of the Device)

Where the User turns on the daily reminder, the Application asks for permission to send notifications. The reminder is scheduled on the device by the Application and is delivered by the operating system; no reminder is sent through any server.

AndroidIn the Android version of the Application, the Application also schedules the daily reminder again after the device restarts or its time zone changes.

The Application does not use the camera, the microphone, the location of the device, the contacts of the User, the photographs of the User, or any other protected function of the device.

Article 8 (Storage, Backup and Export)

Study Records are stored on the device of the User. A record of the events of the Application is also kept on the device, separately from Study Records and outside any backup, and is sent nowhere but as Usage Data.

The Application also keeps on the device the date and time at which it was first installed on that device. This date is not transmitted to the Developer and is not part of Usage Data; it is kept so that the Application can recognise an installation made before a future change to the Application, such as the introduction of a charge.

iOSIn the iOS version of the Application, the date of first installation is kept in the keychain of the device, so that it remains on the device after the Application is deleted and is found again when the Application is installed again on the same device.

iOSIn the iOS version of the Application, Study Records are included in the backup of the device that the User makes to iCloud or to a computer, so that they can be restored together with the device. Such a backup is held by Apple or on the computer of the User, is subject to the terms between the User and Apple, and is not accessible to the Developer.

AndroidIn the Android version of the Application, Study Records are included in the backup of the device to the Google account of the User and in a transfer to a new device, so that they can be restored. Such a backup is held by Google, is subject to the terms between the User and Google, and is not accessible to the Developer.

Where the User chooses to export the data of the Application, the Application writes the Study Records to a file and hands it to the User, who decides where it is saved or sent. The Developer does not receive the file.

Article 9 (Purchases)

The Application may at present be used free of charge and offers nothing for sale. Where a later version of the Application offers an in-app purchase, the following applies.

iOSAn in-app purchase is sold and processed by Apple through the App Store. The Developer does not receive the name, payment details or Apple Account of the User; the Application learns from Apple only which purchases have been made.

AndroidAn in-app purchase is sold and processed by Google through Google Play. The Developer does not receive the name or payment details of the User; the Application learns from Google only which purchases have been made.

Article 10 (Children)

The Application is intended for learners of junior high school age and older. It is not directed to children under the age of 13, and the Developer does not knowingly collect personal information from children under the age of 13.

Article 11 (Deletion of Information)

The uninstallation of the Application deletes all data stored by the Application on the device of the User, except, in the iOS version, the date of first installation kept in the keychain of the device as described in the Article entitled "Storage, Backup and Export", which is deleted when the device is erased. A backup of the device or an export file the User has made is deleted by the User where it is kept.

The User may request the deletion of any content error report the User has sent, or of Usage Data associated with the installation of the Application, by contacting the Developer at the address set forth in the Article entitled "Contact".

Article 12 (External Transmission / 外部送信に関する公表事項)

本アプリは、電気通信事業法第27条の12に基づき、利用者の端末から外部へ送信される利用者に関する情報について、以下のとおり公表します。

本アプリにはアカウントがなく、氏名、メールアドレス、広告識別子は送信しません。Google アナリティクスによる送信を止めたい場合は、本アプリをアンインストールしてください。送信済みの情報の削除は、下記「Contact」の連絡先までご依頼ください。

Article 13 (Amendment of this Policy)
