Information that must be retained under applicable law is stored separately in a separate storage space and destroyed immediately upon expiry of the retention period.

8. Users' Rights and How to Exercise Them

Users may exercise the following rights against the Company at any time, and the Company shall take action without delay within the period prescribed by applicable law.

Rights may be exercised through the settings screen within the Service or by email (dev@intellieffect.com), and may also be exercised through a legal representative or an authorized agent. In such a case, a power of attorney in accordance with applicable law must be submitted.

The exercise of rights may be restricted where applicable law mandates the collection or retention of the relevant personal information, and in such a case the reason will be provided.

9. Cookies, Analytics, and Advertising Tools

The Company uses cookies essential to providing the Service, such as for maintaining login sessions. Essential cookies are required for use of the Service, and if blocked in the browser, some functions such as login may not be available.

The Company uses Vercel Web Analytics and Speed Insights to understand service usage (visitor counts, page views, referral sources) and web performance (loading speed, etc.). These tools do not use cookies (cookieless) and do not collect information that can identify an individual user.

Separately from the above, the Company uses Google Analytics 4 to analyze how the Service is used. This tool stores cookies on the user's device to distinguish visitors (such as _ga and cookies beginning with _ga_), and collects visit date and time, session duration, pages viewed, referral source, device and browser information, and approximate location (city level). The information collected is processed in a form that does not directly identify an individual, and is retained for 14 months.

Through the use of Google Analytics 4, the above information is transferred to and processed on servers operated by Google LLC (United States). The items transferred are the same as those described in the preceding paragraph, and the purpose of the transfer is analysis of Service usage. Users who do not wish for such transfer may block collection using the methods described below.

The Company uses Meta Pixel (Meta Platforms, Inc.) and Google Ads tags (Google LLC) to deliver targeted advertising and measure advertising performance. These tools store cookies and advertising identifiers on the user's device and collect ad clicks, referral paths, and conversion actions within the Service (such as sign-up and inquiry). The information collected is used for advertising performance measurement, delivery of targeted advertising, and delivery of advertising to similar audiences, and is transferred to and processed on servers operated by each provider (United States).

Users can block collection by enabling their browser's tracking prevention features (such as Safari's 'Prevent Cross-Site Tracking,' Chrome's 'Block third-party cookies,' or Firefox's 'Enhanced Tracking Protection'), or by installing the 'Google Analytics Opt-out Browser Add-on' provided by Google (https://tools.google.com/dlpage/gaoptout). Targeted advertising can be opted out of separately through Meta Ad Preferences (https://www.facebook.com/adpreferences) and Google Ads Settings (https://adssettings.google.com). This has no effect on use of the Service.

10. Measures to Ensure the Safety of Personal Information

The Company takes the following measures to ensure the safety of personal information.

  1. Administrative measures — establishing and implementing an internal management plan, minimizing access privileges to personal information, and managing access records
  2. Technical measures — one-way encrypted storage of passwords, encryption of data in transit (TLS), database access control, and application of Row Level Security
  3. Physical measures — utilizing the cloud provider's physical access controls and security certification systems
  4. Minimizing access privileges to, and managing access logs for, highly sensitive information such as SNS handles

11. Data Protection Officer and Contact

The Company designates a Data Protection Officer as set out below, who oversees personal information processing and handles users' complaints and remedies relating to the processing of personal information.
