Terms of Service

Last updated: May 4, 2026

These Terms of Service ("the Terms") set out the conditions for use of RC Pit Spec ("the App"). Users may use the App on the condition that they agree to these Terms.

Article 1 (Application)

These Terms apply to all relationships related to the use of the App between users and KG App Lab ("the Operator").

Article 2 (Account Registration)

The App can be used without account registration. When posting via the "Pit Lane" feature, users may optionally enter a public handle name (displayed as "Anonymous" if left blank).

Article 3 (Premium Plans)

1. The App offers two paid plans (Basic / Pro), available as monthly or yearly subscriptions. Pricing and feature details are shown on the plan selection screen inside the App.
2. Payments are processed through in-app purchases on the Apple App Store or Google Play Store.
3. Subscriptions auto-renew unless canceled at least 24 hours before the end of the current period.
4. Subscription management and cancellation must be performed via each store's subscription management screen.
5. Pricing, feature contents, and ticket allocations may be changed with prior notice.

Article 4 (Ticket System)

1. The App's AI features (AI diagnosis / AI conversation) are managed under a unified ticket system. 1 ticket = 1 diagnosis or 1 conversation session.
2. Free users may use up to 3 tickets per 24 hours. Each feature requires viewing a rewarded ad before launch.
3. Premium users receive monthly tickets (Basic 15 / Pro 50).
4. Multiple turns within a single conversation session consume only 1 ticket. The turn limit per session is Free 3 / Basic 10 / Pro 30.
5. Unused tickets do not roll over to the next cycle. Remaining tickets at the time of cancellation are not refunded.

Article 5 (AI Features)

1. The App's AI diagnosis and AI conversation features generate responses using the Google Gemini API.
2. AI responses are reference information only. The Operator does not warrant the accuracy, completeness, or fitness for a particular purpose of the content.
3. User responsibility: The Operator is not responsible for outcomes resulting from setting changes, race participation, or equipment purchases based on AI responses. Final judgments must be made by the user.
4. Do not perform operations that fall outside manufacturer-specified limits, or operations with risk of fire, breakdown, or personal injury, even if suggested by the AI.

Article 6 (AI Character Feature)

In conversation mode, users can select from multiple AI characters to converse with. Character switching is a premium-plan-only feature. Each character is a fictional persona and is not associated with any real person or organization. Disclaimers regarding response content follow Article 5.

Article 7 (Sharing Content)

1. Setting data shared via the "Pit Lane" feature is viewable by other users.
2. Copyright in shared data belongs to the poster, but the Operator may use it within the scope necessary to provide the service.
