Privacy Policy

In this Privacy Policy, "DeNA", "we", "us", or "our" means DeNA Co., Ltd. and its subsidiaries.
Your privacy is important to DeNA. We designed our Privacy Policy to cover how we collect and use your information in connection with use of our Manga Box application and website ("Services"). By using our Services in any territory outside of Japan you agree to our collection and use of your information, including your personal information, as described in this Privacy Policy. If you are using the Service in Japan, please refer to this membership agreement. So please take a moment to learn the five W's, the how, and other important matters about the information we collect and how we use it. If you have any questions, please contact us.

The What

In the course of using our Services, you may provide us, directly and indirectly, with both personal and non-personal information. Personal information is information that can be used to identify you as an individual, and might include your name, phone number, pictorial representation, email address, postal address, etc. Non-personal information is information that does not permit direct association with you. Both personal information and non-personal information may be used alone or in the aggregate with information collected from other users. Certain non-personal information would be considered a part of your personal information if it were combined with other identifiers (e.g., combining your zip or postal code with your street address) in a way that enables you to be identified. But the same pieces of information are considered non-personal information if they are taken alone or combined only with other non-personal information (e.g., your viewing preferences).

The Why

Our primary objective in collecting your information is to provide you with a superior and personally relevant user experience. To achieve this, your information may be used as follows:

  • - To help us develop, deliver, and improve our Services, including the following aspects of our Services:
  • communication with users
  • authentication purposes
  • provide Services and Services-related content
  • develop new features and functions to enhance the Services
  • provide system maintenance and handle system malfunctions
  • provide Service-related announcements, newsletters and/or other communications
  • invoice fees, calculate charges and provide payment services
  • provide affiliate and loyalty programs
  • recommending Services-related products or services of interest directly to you
  • delivery and targeting of advertising in the Services
  • tracking of advertisement fulfillment metrics in the Services
    • - For market research purposes that support our efforts to deliver a more valuable service to our community of users, including using your information to contact you with announcements, newsletters, and promotional materials related to our Services or to offer you opportunities to participate in surveys, contests, or sweepstakes (any of these a "Promotion") via our Services.
    • - To provide end-user support such as responding to inquiries and complaints.
    • - To prevent and take measures against fraud, illegal activities, infringement of our rights or interests, or breaches of our Membership Agreement and this Privacy Policy.
    • - To send important notices, such as changes to our Membership Agreement, this Privacy Policy, or other Services-specific policies. Because this information is important to your interactions with us, you may not opt out of receiving these communications.
    • - To audit and analyze data for technical administration, to improve our Services, and for end-user communications.

For location-based Services, we may collect, use, and share precise location data, including the real-time geographic location of the device you use to access or use our Services ("Device"). Unless you explicitly opt-in to permit the use and sharing of your personal information regarding your geographic location, your location data will only be collected and used anonymously in a form that does not personally identify you.

The When

Your information is collected by us when you directly interact with our Services and otherwise through use of our Services via your Device.
When you use our Services, we collect information related to your Device as described in "The How" section below.

If you choose to participate in a Promotion, we may request that you provide us with personal information such as your email address or postal address in order to administer your participation in the Promotion.

The How

As already mentioned, we may collect information from you when you directly interact with our Services and otherwise through your access to or use of our Services.
Direct interaction includes such actions as creating a username, providing an email address, or posting to walls and other forums through our Services. You specifically agree that we shall have the right, but not the obligation, to collect and store the information referred to in this paragraph.

We may also collect your information from third parties who provide it to us, including other users of our Services.

As is standard practice, we do use "cookies" in connection with the Services. A cookie is a small string of text placed on your Device. In addition to strictly necessary cookies that enable us to provide our Services (such those that provide your SNS log-in status when that account ID is linked to functionality on the Services), we may use both performance-gauging and functionality-gauging cookies. Performance-gauging cookies reveal how you use the Services, for instance, which content is the most popular, how much time users are spending there, and what advertising is relevant to you, which helps us provide an optimized experience (we may engage third parties to carry out this analysis, and they may set their own "third party" cookies--see "The Who" for more). Functionality-gauging cookies enables us to remember certain choices you make in interacting with the Services, for instance, any geographic location, language, or fonts you choose, which helps us tailor the Services to your preferences. Neither performance-gauging cookies nor functionality-gauging cookies collect information in any way that personally identifies you.

Except for cookies strictly necessary for enabling us to provide our Services, you have the option to disable cookies stored on your browser by changing the options in your browser to stop accepting cookies or to prompt you before accepting a cookie from the content you visit. Note that local shared objects or "flash cookies", which are different from HTTP cookies, may require different treatment for removal or disablement depending on the version of browser used. If you do not accept cookies, you may not be able to view or use parts of our Services due to limited functionality. Some cookies we use may be stored using a web-browsing component other than a browser application--these cannot be disabled on your Device, but the information collected does not personally identify you, and does not permit tracking between Services.

Some of our Services, including messaging, may use "click-through URLs" linked to other content on our Services. We track this click-through data to help us determine interest in topics, Services usability, and other measures of user engagement.

In using our Services, our servers record information sent from your Device, which may include information such as device type, mobile carrier, unique device identifier ("Device Number"), Internet Protocol ("IP") address, browser type, language, Internet service provider, network status, time zone, geo location, referring and exit pages, time spent, information searched for, time and date stamp, clickstream data, and other statistics on your use of our Services; for some software no Device Number is recorded but in those and other cases we may have access to a generated and non-permanent unique identification number functionally matched with your Device ("Matching Number").


The Who

Our Responsibility for Our Collections

While we will collect and use your information as explained in this Privacy Policy, as a user of our Services you may be permitted to use and create your own profile, connect with other users of our Services, and send messages and transmit information through various channels. Please remember that any communications you have via our Services, depending on, for example, the functionality of the Services used, may reveal information such as any Services profile(s) you create (including your username(s), profile image(s), and profile status/comments, "Profile") and the content of your communications, making this information publicly available to other users. We are not responsible for the activities of other users or other third parties with whom you choose to provide your information or otherwise interact.

Interaction with Other Users

You understand and agree that your Profile may be viewable in the Services by other users of the Services and may also be searchable. You also understand and agree that certain in-Services information of your User Content may be displayed and viewable in the Services by other users of the Services. For example, other users of the Services may be able to see your User Content ranking. Note that where available you may have the option to change certain aspects of your Profile (e.g., profile image).

Persons with Whom We May Share Your Information

You agree that we may share your information as follows:

  • With Third Parties for Industry Analysis and Advertising

You agree that we may share technical information related to your Device ( such as IP address, Matching Number, or Device ID), aggregated non-personal information, and anonymous information with advertisers, ad networks, and analytics analysis entities ("Ad Entities") with whom we have strategic relationships, and Ad Entities may also be permitted to collect such information via cookies and other tracking technologies. This information may be used to undertake user trend analyses, demographic profiling, and analytics, and to provide to you tailored and personalized ads and advertising (behavioural advertising). Please note, though, that some Ad Entities also act as Service Providers (defined below) for us, and in those cases we may share your information as explained below.

  • With our Service Providers

Sharing of your information may also occur where we engage or employ service providers, vendors, or other third parties to help us provide our Services (each a "Service Provider") (e.g., improvement of our Services' features, promotion and marketing, administration, analytics, customer service, cloud storage, hosting, and other related services), to provide the Services on our behalf, or to assist us in analyzing how our Services are being used. Our Service Providers may have access to your personal information only to perform these tasks on our behalf, and they are obligated not to disclose or use your personal information for any other purpose.

  • With Certain Third Parties in Special Circumstances

At times, we may disclose information about you to law enforcement officials or private parties as we believe necessary or appropriate to respond to claims and legal process (including subpoenas), to protect the property and rights of DeNA or a third party, to protect the safety of the public or any person, or to prevent or stop activity we may consider to be, or to pose a risk of being, illegal, unethical, or legally actionable activity. Under another special set of circumstances, for example, in connection with a merger, acquisition, reorganization, or sale of assets, or in the event of bankruptcy, we may sell or transfer some or all of our assets, and in this connection we may transfer all of your information, including personal information, to any successor entity.

Policy Not to Collect Personal Information from Children

None of our Services in the U.S. is intended for children under the age of 13 ("children") and we do not knowingly collect personal information from, or store personal information of, children. For all other territories, no personal information is collected from anyone below legal age of majority. We will upon notice or discovery take all reasonable efforts to erase or destroy any such personal information that may have been collected or stored by us without our knowledge.

The Where

You understand and agree that we may transfer your information to and process it in Japan and other countries. Your consent to this Privacy Policy by accessing or using our Services represents your consent to such transfer and processing.

Changes to Privacy Policy

We reserve the right to change this Privacy Policy at any time. If we change this Privacy Policy in a material way, we will give notice of that in the Services, on our website (, and/or by email to any email address we may have for you at that time. Your use of our Services after we have changed the Privacy Policy will indicate your consent to the updated Privacy Policy.

Other Important Matters

Push and Local Notifications

Unless you indicated otherwise at installation or chose not to receive push and local notifications where the option is made available to you, you agree that we may send push and local notifications to your Device concerning updates, events, and special offers for the Services installed on your Device. Please note that where available you may have the option of deactivating push or local notifications by changing the settings of the application of your Device.

Protecting Your Information

We take your privacy very seriously and employ reasonable administrative, physical, and electronic measures to safeguard information received from you and held by us against identity theft and unauthorized access or alteration. In addition, we will take reasonable steps to assure that third parties to whom we transfer any data will provide sufficient protection of your personal information. We do not and will not, at any time, request your credit card information, your username, login password, or any national identification numbers in a non-secure or unsolicited communication (e.g., via e-mail, telephone, or mobile device). We will not keep your personal information any longer than needed for the purpose it was collected or than is necessary for legal or legitimate business purposes.

We will make any legally required disclosures of any breach of the security, confidentiality, or integrity of your unencrypted electronically stored "personal data" or "personal information" (as defined in applicable statutes on security breach notification) to you via email or conspicuous posting on our website in the most expedient time possible and without unreasonable delay, consistent with (i) the legitimate needs of law enforcement; or (ii) any measures necessary to determine the scope of the breach and restore the reasonable integrity of the data system.

Corrections and Certain Opt-Out Options

If you have any concerns with the way we collect and handle your personal information, or would like to correct or request that we delete such personal information held by us, please contact us. We will use commercially reasonable efforts to honor your request; please note, though, that at a minimum we may retain an archived copy of your records as required by law or to send necessary communications to you under this Privacy Policy.

Where you share information with other users through the communication channels of our Services, you generally should not expect to have any ability to modify or remove such communications. Nor should you expect us to modify or delete your comments upon your request.

For a Promotion, you have the option to opt out at any time from participation in such Promotion and the receipt of any related communications by following unsubscribe instructions provided in the relevant communications, or by selecting not to receive communications from us where the relevant media service offers that option.

You may have the option of deleting a Matching Number by performing a dedicated reset or a Device factory reset from the settings of your Device. You understand that by deleting a Matching Number any and all data you had prior to the reset may be lost and irretrievable, and that you may not be able to view or use portions of our Services due to limited functionality.

Other Websites and Services

Our Services may contain links to other websites and online services or offers from third parties. For example, our Services may include offers from third party advertisers or the ability to engage in transactions with such entities. If you choose to participate in offer-linked information requests or "click on" an advertisement or another third party link, you may be directed to that third party's website or service and/or be prompted to provide personal information in connection with such activity.

The fact that we link to a third party website or service is not an endorsement or representation of our affiliation with that third party, nor is it an endorsement of such third party's privacy or information security policies or practices or their compliance with any laws. We do not exercise control over third party websites or services, and this Privacy Policy does not apply to information collected by them, including Ad Entities. These other websites or services may place their own cookies or other tracking devices on your computer or mobile device, or collect data or solicit personal information from you. Other websites and services follow different rules regarding the use or disclosure of the personal information you submit to them. We encourage you to read the privacy policies or statements of the other websites and services you use and the terms of the offers in which you participate. You agree that we are not responsible for, nor will we be liable to you or any third party for, your interaction with such third parties or the information requests initiated by such third parties or the subsequent use, treatment, or dissemination of the information you provide to them.

California Residents: Your California Privacy Rights

California law permits those of our customers who are California residents the right to request certain information regarding our disclosure of personal information to third parties for their direct marketing purposes. To make such a request, please contact us.

To the extent that any of our mobile applications of the Services collects personally identifiable information, that is done only as strictly necessary to enable us to provide those Services (see The How, above), and this cannot be disabled by "do not track" or other mechanisms available via your mobile Device's browser.
