Privacy Policy​

TLC (“we,” “us,” or “our”) operates the AI Usage Skill Visualizer (the “Service”).

We recognize the importance of protecting users’ personal information and other information submitted through the Service. This Privacy Policy explains what information is processed, how it is used, and how it is handled.

The Service may process the following categories of information.

1. Information submitted for analysis

• Any information voluntarily included in the inquiry

3. Generated information

The Service may temporarily generate:

• Device and operating-system information

• Date and time of access

• Pages or functions used

• Session identifiers

• Error and security logs

• Cookie and similar technology information

Article 2 — Purposes of Processing

Information is processed only as reasonably necessary for the following purposes:

• Providing the Service

• Performing the analysis requested by the user

• Generating scores, comments, results, and PDF reports

• Maintaining the user’s session while the Service is being used

• Responding to inquiries

• Preventing misuse and maintaining security

• Diagnosing technical errors

• Measuring general usage and improving the user interface

• Complying with applicable laws and legal obligations

• Providing important notices concerning the Service

Submitted conversation logs and outputs are not used by TLC for advertising or sale to third parties.

Article 3 — Handling of Submitted Conversation Logs and Outputs

Conversation logs, text, files, images, URLs, and other outputs submitted by users are processed only to perform the analysis requested by the user and generate the requested results.

TLC does not intentionally retain submitted conversation logs or submitted outputs after they are no longer required to complete the requested processing.

Submitted conversation logs and outputs are not used by TLC to train AI models or to improve the scoring or analysis system.

TLC does not manually review submitted content for general service improvement.

Submitted content may be reviewed only in limited circumstances, such as:

• When the user voluntarily provides the content as part of a support inquiry

• When review is necessary to investigate a specific technical problem reported by the user

• When necessary to prevent misuse or address a security incident

• When required by law

Submitted information may be held temporarily in application memory, session state, caches, or processing systems while the analysis or PDF generation is being performed.

External service providers may temporarily process submitted information within the scope necessary to provide the Service. Their handling and retention of information are governed by their respective security measures, contracts, and privacy practices.

Users should not submit sensitive personal information unless it is necessary for the analysis.

Users are responsible for ensuring that they have the right to submit conversation logs, files, images, and other information containing data relating to third parties.

Article 4 — Generated Results and PDF Reports

Analysis results and PDF reports are generated for the user’s requested evaluation.

TLC does not provide permanent cloud storage for generated reports.

PDF reports are intended to be downloaded and stored by the user.

Generated data may be held temporarily during the active session or for the technical period necessary to complete generation and download.

Once session data is no longer available, TLC may not be able to restore a previously generated analysis result or PDF report.

Article 5 — Automated Analysis

The Service uses automated processing to analyze submitted information and generate scores, comments, and evaluation results.

These results are reference assessments based only on the submitted content.

They are not intended to produce legal effects or other similarly significant decisions concerning the user.

Users should not rely on the results as the sole basis for employment, education, financial, legal, medical, or other important decisions.

Article 6 — External Service Providers

The Service may use external service providers for functions including:

• Application and website hosting

• AI-based analysis processing

• File and text processing

• PDF generation

• Access analytics

• Error monitoring

• Security

• Inquiry management

Only information reasonably necessary to perform the applicable function is provided to such service providers.

Depending on the provider and its infrastructure, information may be processed on servers located outside Japan or outside the user’s country of residence.

External service providers process information in accordance with their own privacy policies, contractual obligations, and applicable laws.

TLC does not sell users’ personal information or submitted content.

Article 7 — Disclosure to Third Parties

TLC does not disclose personal information to third parties except in the following circumstances:

• When the user has given consent

• When disclosure is necessary to provide the Service through an external service provider

• When disclosure is required by law, court order, or governmental authority

• When necessary to protect a person’s life, physical safety, rights, or property

• When necessary to prevent fraud, misuse, or a security threat

• When necessary in connection with a merger, transfer, succession, or reorganization of the Service, subject to appropriate safeguards

Article 8 — AI Visualization Log Extractor

TLC may provide the browser extension AI Visualization Log Extractor.

The extension supports designated AI services, including:

• ChatGPT

• Claude

• Gemini

The extension accesses conversation content displayed on a supported AI service only when the user explicitly operates the extension.

The extension formats the conversation displayed on the page into a text log that can be used with the AI Usage Skill Visualizer.

The extracted content is processed locally within the user’s browser and is displayed to the user or copied to the user’s clipboard.

The extension itself does not automatically:

• Transmit extracted conversation content to TLC

• Upload extracted content to the Service

• Store extracted conversation content on an external server

• Start an analysis

• Access unrelated pages or conversations

When a user chooses to paste an extracted log into the AI Usage Skill Visualizer, the handling described in Article 3 applies.

Article 9 — Cookies and Similar Technologies

The Service and its website may use cookies, session storage, local storage, and similar technologies for purposes including:

• Maintaining application sessions

• Preserving temporary interface state

• Providing essential website functions

• Preventing misuse

• Analyzing general access and usage trends

Users may manage or disable cookies through their browser settings or available website cookie settings.

Disabling essential cookies or storage may prevent some functions from operating correctly.

Article 10 — Retention

TLC retains information only for as long as reasonably necessary for the purposes described in this Privacy Policy.

Retention periods differ depending on the type of information.

• Submitted conversation logs and outputs are not intentionally retained by TLC after the requested processing is complete.

• Session information and generated PDF data may be held temporarily for the duration necessary to provide the Service.

• Inquiry records may be retained for as long as necessary to respond to the inquiry and maintain an appropriate record of communications.

• Access, analytics, error, and security logs may be retained according to operational needs and the settings of the applicable service provider.

• Information may be retained for a longer period when required by law or necessary to establish, exercise, or defend legal claims.

Information that is no longer required will be deleted, anonymized, or allowed to expire within a reasonable period.

Article 11 — Security Measures

TLC takes reasonable organizational and technical measures to protect information against:

• Unauthorized access

• Leakage

• Loss

• Alteration

• Destruction

• Improper use

However, no internet-based service or electronic transmission method can guarantee absolute security.

Users should review submitted conversation logs and files and remove unnecessary personal or confidential information before submitting them.

Article 12 — User Requests

Subject to applicable law, users may request:

• Disclosure of personal information retained by TLC

• Correction of inaccurate information

• Deletion of retained information

• Suspension or restriction of certain processing

• Information concerning the handling of their personal information

Because submitted conversation logs, outputs, and generated reports are not intended to be retained by TLC after processing, TLC may not be able to retrieve, disclose, correct, or delete such information after the session or temporary processing period has ended.

Requests may be submitted through the Service’s contact page.

TLC may request reasonable information to verify the identity of the person making the request.

Article 13 — Use by Minors

Users who are minors must obtain the consent of a parent or legal guardian before using the Service.

Users should not submit personal information relating to children unless they have the authority and a valid reason to do so.

Article 14 — Changes to This Privacy Policy

TLC may revise this Privacy Policy when necessary due to:

• Changes to the Service

• Changes to data-processing practices

• Changes to external service providers

• Changes to applicable laws or regulations

The revised Privacy Policy will take effect when it is posted on this website, unless a different effective date is stated.

Material changes may be announced through the Service or website.
