Privacy Policy
This policy explains how personal information and similar data are handled in the Hagune app (the "App") and this website (the "Site"). The App is built around the basic principle that your daily records stay within your device.
Business Operator
Personal information handling operator: 9448-4698 Quebec Inc.
For inquiries about the App or Site, and for requests for disclosure or complaints, please use the "Contact and Complaints" channel listed at the end of this policy.
Core Principle: Local-First
Your records in the App are stored only within your device and are never sent to any server. No one can view the contents of these records.
The App does not require you to register an account. When you use voice input, its processing is also carried out within your device.
Information We Collect and Purposes of Use
The information collected through the App and Site, and its purposes of use, are as follows. Some features are optional (opt-in), and information is sent only when you have consented.
- To provide and maintain the App and Site and to prevent unauthorized use (connection information necessary for communication, such as IP addresses)
- To provide optional features (the information specified for each feature; collected and sent only when you have consented)
- To respond to inquiries
- To analyze usage of the Site (cookies, etc.; see "Cookies and Analytics" below; website only)
- To improve the quality of the service (anonymous aggregate information)
Handling of On-Device Data (Backup and Deletion)
You can export (back up) your records in the App at any time from the settings screen. You can also completely delete your saved records yourself at any time by deleting the app data on your device. Deleted data cannot be restored.
Information Sent by Optional Features
The App includes optional features that create results based on information you provide (such as your date of birth and name). Before use, you review a consent screen, and only when you consent is the necessary information sent to a third party located overseas (a service provider).
The information sent is used only to create the result and is not stored on our servers. The created result is stored only within your device. Information not needed by the feature, such as information about your mental health, is never sent.
Consent to this feature is voluntary. Even if you do not consent, you can use the other features as usual. You can withdraw consent at any time. This feature is for entertainment and is not intended for medical or therapeutic purposes. It is not available to minors.
External Services and Subcontractors
To provide the App and the Site, we may entrust some operations — such as hosting and cloud infrastructure, usage analytics, and in-app purchase (payment) processing — to external providers. We require such providers to handle information only within the purposes set out in this policy, and we supervise them.
In-app purchase payments are processed through the respective app stores; we do not receive payment information such as credit card numbers.
Provision to Third Parties Overseas (Cross-Border Transfer)
In the optional features described above, and in the Site's analytics, information may be processed by providers located overseas (including the United States) (the Site's analytics does not apply to the App). These constitute provision to a third party located overseas, and in each case are premised on your prior consent (including, for the Site's analytics, consent given through browser settings). The personal-information protection regime of the destination country may differ from that of your own country. For such transfers, we have put protective measures in place based on our contracts with the subcontractors.
Restrictions on Provision to Third Parties
We do not provide collected information to third parties beyond the scope of the subcontracting and feature provision described above (except where required by law). We do not provide or sell information to third parties for advertising purposes.
Usage Measurement (Telemetry)
To improve the quality of the service, we may understand usage of the App only through anonymous aggregation (such as counting occurrences). This never includes the content of your records, mood scores, names, or other free-text input. For the Site's analytics, please see "Cookies and Analytics" below.
Security Measures
To securely manage the information we collect, we take reasonable security measures such as encryption of communications, access control, and minimization of the information collected.
Cookies and Analytics (Site only)
On this Site, to understand usage and improve the quality of the service, we use analytics tools provided by Google. Using technologies such as cookies, we collect information such as page views, referrer, approximate region, and device/browser environment. The collected information is processed by the respective providers and may be processed overseas, including in the United States (see also "Provision to Third Parties Overseas").
These cookies and analytics apply to the Site only. The App does not use cookies and does not use these analytics tools. Your records in the App are stored only within your device, and your browsing history and similar data are not sent to any external analytics provider (see "Core Principle: Local-First" above).
Children's Personal Information
Some optional features are not available to minors (they are restricted by default based on age group). The App is not directed exclusively at any particular age group.
Your Rights (Disclosure, Correction, Deletion, etc.)
You can manage and delete your records in the App yourself at any time by exporting (backing up) from the settings screen and by deleting the app data on your device.
In addition, requests for disclosure, correction, suspension of use, or deletion of retained personal data are accepted at the channel below. After verifying your identity, we will respond without delay in accordance with the law. No fee is charged for such requests.

Inquiries, and requests for disclosure or complaints, are accepted at the following channel.

If we change this policy, we will announce it on this page. Important changes will also be explained clearly within the App.
