This Privacy Policy explains how we collect, use, disclose, store, and otherwise process information when you use the Service, and describes the choices and rights available to you.

1. Information We Collect
The information we collect depends on how you use the Service and the permissions you choose to grant.
A. Information You Provide
Account Information
To create an account and use the Service, you provide an email address.
We use your email address to:
create and maintain your account;
send you a verification code that allows you to sign in to the Service;
associate your account with your identity within the Service.
When you register, we assign your account a unique account ID. After creating an account, you may choose a nickname or display name to use within the Service.
Your account is directly associated with the email address you used to register.
We do not use passwords for account access. Sign-in is performed using a verification code sent to the email address associated with your account.
Important: You are responsible for maintaining access to the email address associated with your account. If you lose access to that email address, we may not be able to verify that you are the account owner or recover access to your account. In such circumstances, we may be unable to restore access to the account or its associated content.
Content You Create and Upload
The Service allows you to create and organize content through Flips and related content areas.
Depending on the features you use, you may choose to create or upload content such as:
photos;
videos;
audio;
captions and other text;
links;
other media or materials supported by the Service.
You control the content you choose to create and upload. When you create a Flip, you can choose its visibility setting:
Private Flips are visible only to you, the creator of the Flip.
Public Flips are visible to other users of the Service.
You can choose the visibility of your Flips in accordance with the options available in the Service. You should carefully consider what information you include in a Public Flip, as it may be viewed by any user of the Service.
You are responsible for the content and information you choose to upload or make available through the Service. You should avoid including sensitive personal information or personal information about other people in Public Flips unless you have an appropriate legal basis or their permission to do so.
B. Information Collected Automatically
When you use the Service, we may automatically collect certain technical and usage information necessary to operate, maintain, secure, and improve the Service.
This may include:
information about how you use the Service, such as features used, actions taken, and timestamps;
device type and model;
operating system version;
application version;
language and regional settings;
technical and security-related information, such as your IP address.
We may use this information to operate the Service, maintain security, prevent abuse, troubleshoot technical issues, and improve the Service.
C. Device Permissions
The Service is currently available on iOS through the Apple App Store.
The Service may request access to certain features of your iOS device. You can choose whether to grant these permissions and can change them at any time through your device settings.
Camera
If you grant camera permission, we may access your device's camera when you choose to use camera-related functionality within the Service, such as creating or uploading content.
We do not access your camera when you are not using a feature that requires camera access.
Location
If you grant location permission, we may access your device's location solely to provide location-based features, including displaying weather information relevant to your location.
We do not store your precise location as part of your account or retain it for future use. Location information is used only as necessary to provide the relevant weather feature.
You can disable location access at any time through your iOS device settings. If you do not grant location permission, you may still use the other features of the Service, but location-based weather information may not be available.
D. Information You Choose to Provide Through the Service
Some features of the Service allow you to voluntarily provide additional information through the content you create or upload.
The information you choose to include in your Flips or other content may be visible to other users depending on the functionality and settings of the Service.
Please consider carefully what information you choose to share through the Service, particularly if that information could identify you or another person.
2. How We Use Information
We use information we collect for the following purposes:
Providing and Operating the Service
We use information to:
create and maintain accounts;
authenticate users;
provide access to the Service;
store and deliver user-created content;
maintain profiles and Flips;
provide features requested by users;
process device permissions and location-based features;
maintain the functionality and performance of the Service.
Personalization and Service Improvement
We may use information about how you use the Service to:
personalize your experience;
organize or recommend content;
improve feed ranking and content organization;
understand how users interact with features;
identify technical issues;
develop and improve existing and future features.
Safety and Security
We may use information to:
detect and investigate suspicious activity;
prevent fraud, abuse, and unauthorized access;
protect user accounts;
protect the security and integrity of the Service;
enforce our Terms of Use or other applicable terms;
investigate violations of applicable law.

verify account ownership where necessary;
provide customer support.
Legal Compliance
We may process information where necessary to:
comply with applicable laws and regulations;
respond to valid legal requests;
establish, exercise, or defend legal claims;
protect our legal rights.
3. Legal Bases for Processing in the EEA, UK, and Other Applicable Jurisdictions
If you are located in the European Economic Area ("EEA"), the United Kingdom ("UK"), or another jurisdiction where a legal basis is required, we process your personal information based on one or more of the following legal grounds, as applicable:
Performance of a Contract
We process information when it is necessary to provide the Service you have requested, including creating and maintaining your account and providing the features of the Service.
Legitimate Interests
We may process information where necessary for our legitimate interests, including:
operating and improving the Service;
maintaining security;
preventing fraud and abuse;
protecting our users and systems;
understanding Service usage;
defending our legal rights.
When relying on legitimate interests, we consider and balance those interests against your rights and freedoms.
Consent
Where required by law, we rely on your consent to process information for specific purposes, such as certain optional device permissions or location-based features.
You may withdraw consent at any time where processing is based on consent. Withdrawal does not affect the lawfulness of processing carried out before withdrawal.
Legal Obligations
We may process information where necessary to comply with a legal obligation applicable to us.
4. User-Generated Content and Visibility
The Service allows you to create and organize content through Flips.
When you create a Flip, you can choose whether it is Private or Public:
Private Flips are visible only to you, the creator.
Public Flips are visible to all users of the Service.
You can change a Private Flip to Public at any time. However, once a Flip has been made Public, you cannot change it back to Private. Making a Flip Public is therefore an irreversible action with respect to its visibility setting.
Public Flips and Forwarding
When you make a Flip Public, it may be viewed, collected, or forwarded by other users of the Service.
If another user forwards or otherwise reuses a Public Flip, a copy or reference to that Flip may become part of that user's collection or content within the Service. Such copies or references may remain available even if you later delete or modify the original Flip.
For this reason, you should carefully consider the information and content you include in a Public Flip before making it Public. You should avoid including sensitive personal information, passwords, financial information, precise real-time location information, or personal information about other individuals in a Public Flip unless you have an appropriate legal basis or their permission to do so.
You are responsible for the content and information you choose to create, upload, and make available through the Service.
Deletion of Flips
You may delete Flips and other eligible content through the Service where the relevant functionality is available.
When you delete an original Flip, it will no longer be available as the original Flip through the Service. However, if another user has previously forwarded, collected, or otherwise reused a Public Flip, copies or references to that content may remain available within the Service and may not be automatically removed when the original Flip is deleted.
We may also retain certain information temporarily in backups or other systems where deletion is not immediately technically possible, or where we are required or permitted by applicable law to retain the information.
5. Automated Processing and Algorithms
The Service uses algorithms and automated processes to operate certain features and improve your experience.
These processes may be used to organize, display, or recommend content and to personalize aspects of the Service based on information such as your interactions with the Service and your use of its features.
These automated processes do not use artificial intelligence or machine-learning models.
We may update or improve the algorithms and automated processes used by the Service from time to time as we develop and improve the Service.
6. How We Disclose Information
We do not sell your personal information.
We do not use your personal information for targeted advertising based on your activity across unrelated third-party services.
We may share or disclose personal information with third-party service providers where necessary to operate, maintain, secure, analyze, and improve the Service. These providers process information on our behalf and, where applicable, in accordance with our instructions.
A. Cloud Hosting, Storage, and Account Authentication
We use Amazon Web Services (AWS) to provide cloud infrastructure, hosting, storage, and related services necessary to operate the Service.
AWS may process and store information associated with your use of the Service, including account information, user-generated content, and other information necessary to operate the Service.
We also use AWS infrastructure to support account authentication, including sending verification codes to the email address associated with your account when you register or sign in.
B. Analytics Providers
We use third-party analytics services to understand how users interact with the Service, monitor usage, identify technical issues, and improve the Service.
We currently use:
Amplitude;
Mixpanel.
These analytics providers may receive information about your use of the Service, which may include:
a hashed or otherwise pseudonymous identifier associated with your account;
IP address, which may be used to determine an approximate geographic location, such as country or region;
device information, such as device type and operating system;
information about your interactions with and use of the Service.
We do not provide these analytics providers with your account email address for analytics purposes.
We use analytics information to understand how the Service is used, measure the performance of features, identify problems, and improve the Service.
The analytics providers may process information in accordance with their own privacy policies and terms of service.
C. Legal and Safety
We may access, preserve, or disclose information where we reasonably believe it is necessary to:
comply with applicable laws or regulations;
respond to a valid legal process or lawful request from a government authority;
protect the rights, property, safety, or security of our users, the public, or the Service;
detect, prevent, or investigate fraud, abuse, security incidents, or other harmful activity;
enforce our agreements and protect our legal rights.
D. Business Transfers
If Nekonomikon Co., Ltd. is involved in a merger, acquisition, corporate reorganization, financing, bankruptcy, or sale or transfer of some or all of its assets, personal information may be transferred as part of that transaction, subject to applicable law.
E. No Sale of Personal Information
We do not sell your personal information to third parties.
We do not use analytics providers to sell your personal information or to provide targeted advertising based on your activity across unrelated third-party services on our behalf.
7. International Data Transfers
Nekonomikon is based in Japan, and the Service may be operated using infrastructure and service providers located in countries outside your country of residence.
Your information may therefore be transferred to, stored in, or processed in countries including the United States.
Where data is transferred from Japan, the EEA, or the UK to service providers located in the United States or other jurisdictions, we rely on recognized legal transfer mechanisms, including European Commission adequacy decisions, the EU-U.S. Data Privacy Framework (where applicable), or Standard Contractual Clauses (SCCs) to ensure your data receives an equivalent level of protection.
You may contact us using the information in the "Contact Us" section if you would like additional information about applicable international transfer safeguards.
8. Data Retention
We retain personal information only for as long as reasonably necessary for the purposes described in this Privacy Policy, including to provide the Service, maintain security, comply with legal obligations, resolve disputes, and enforce our agreements.
Retention periods may vary depending on the type of information and the reason we collected it.
Account Information and User Content
We generally retain account information and user-created content while your account remains active or as necessary to provide the Service.
If you delete content or request deletion of your account, we will delete or anonymize the relevant information from our active systems within a reasonable period, except where we are required or permitted by law to retain it.
Backups
Deleted information may remain temporarily in backups or disaster recovery systems before being deleted or overwritten in accordance with our backup procedures.
Security and Technical Logs
We may retain security and technical logs for as long as reasonably necessary for security, fraud prevention, troubleshooting, system integrity, and legal purposes.
9. Your Rights and Choices
Depending on where you live and subject to applicable law, you may have rights regarding your personal information.
These may include the right to:
access personal information we hold about you;
request correction of inaccurate or incomplete information;
request deletion of your personal information;
request restriction of certain processing;
object to certain processing;
request portability of certain information;
withdraw consent where processing is based on consent;
lodge a complaint with a relevant data protection authority.
Additional Disclosures for United States Residents (e.g., California/CPRA)

We collect this information for the operational business purposes described in Section 2 of this Privacy Policy.
We do not sell your personal information, nor do we share your personal information for cross-context behavioral advertising.
We do not knowingly collect, sell, or share personal information of consumers under 16 years of age.

We may need to verify your identity before fulfilling certain requests. We will use reasonable measures to verify that the person making a request is authorized to do so.
If you are located in the EEA, UK, or another jurisdiction that provides a right to lodge a complaint with a data protection authority, you may exercise that right with the relevant authority in your country or region.
10. Account Deletion
You may delete your account at any time directly within the App through your account settings, or by contacting us at: alina@hi.industries.
When an account deletion request is submitted, we will take reasonable steps to delete or anonymize personal information associated with your account from our active systems within 30 days, subject to applicable law and legitimate retention requirements.
Some information may be retained where necessary to:

resolve disputes;
prevent fraud or abuse;
protect the security of the Service;
establish, exercise, or defend legal claims.
Information that remains in backups may be retained temporarily in accordance with our backup procedures.
11. Security
We use reasonable technical and organizational measures designed to protect personal information against unauthorized access, loss, misuse, alteration, or disclosure.
Depending on the nature of the information and the risks involved, these measures may include access controls, authentication mechanisms, encryption, monitoring, and other security practices.
However, no method of transmission over the Internet or method of electronic storage is completely secure. We therefore cannot guarantee absolute security.
12. Age Requirement and Children
The Service is intended for individuals who are 16 years of age or older.
We do not knowingly collect personal information from individuals under the age of 16. If you are under 16, you may not create an account or use the Service.

If you believe that a person under 16 has provided us with personal information or created an account, please contact us at:
alina@hi.industries
13. Third-Party Services and Links
The Service may contain links to or integrate with third-party services.
This Privacy Policy does not apply to the privacy practices of third parties that we do not control. We encourage you to review the privacy policies of any third-party services you choose to use.
If you use third-party sign-in, authentication, content, or other integrated services, those services may process information in accordance with their own privacy policies and terms.
14. Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes in the Service, our data practices, applicable law, or other operational requirements.
When we make material changes, we will provide notice as required by applicable law and, where appropriate, give you an opportunity to review the updated Privacy Policy before the changes take effect.
The updated Privacy Policy will be posted through the Service or on the applicable website and will include a revised "Last Updated" date.
We encourage you to review this Privacy Policy periodically.
