Terms of Service & EULA

End User License Agreement — Kakei AI

Last updated: April 28, 2026

This application (the "App") is licensed, not sold, to you by HiroBuilds. By downloading or using the App, you agree to all terms of this Agreement.

01 License Grant

We grant you a personal, worldwide, non-transferable, non-exclusive license to use the App on your iOS device. This license is solely for your personal use in accordance with the terms of this Agreement.

02 Core Principles: Privacy & Local-First, No Account Required

We do not require you to create an account and therefore hold no identifying information about you.

Data Ownership & Responsibility: Your financial data is stored locally on your device or in your personal iCloud space. We cannot access or own your data. Because the developer does not store your data, we cannot recover or restore it if you lose data due to not enabling cloud sync, not backing up, switching devices, or uninstalling the App. We bear no liability for such data loss.

The App does not collect any personally identifiable information from users, nor does it actively collect any data from children.

We strongly recommend that you regularly use the built-in Export feature to back up your financial data to a safe location to prevent accidental loss.

03 AI Features & Disclaimer

The App integrates both on-device (MLX/Qwen) and cloud-based (Google Gemini) AI technology:

Not Professional Advice: All analysis, categorization, or predictions generated by AI are for reference only. AI may produce inaccurate information (hallucinations).

Limitation of Liability: The App does not constitute formal investment, legal, or tax advice. We bear no liability for any direct or indirect financial losses arising from reliance on AI-generated results. Please consult a professional before making significant financial decisions.

Free Cloud AI Continuity: The availability of free cloud AI depends on Google's policies. If Google modifies or discontinues its free tier, we will make reasonable efforts to evaluate and introduce an alternative free cloud AI service, but we do not guarantee nor are we obligated to provide this feature permanently.

Quota Limits: Any usage limits on the free tier (such as daily request caps) are set by Google. The developer bears no responsibility for such limits and cannot provide service beyond them.

Service Provided "As Is": The App is provided on an "AS IS" and "AS AVAILABLE" basis. The developer makes no express or implied warranties regarding merchantability, fitness for a particular purpose, non-infringement, accuracy, completeness, reliability, or uninterrupted operation. Your use of the App is at your own risk.

Age & Eligibility: The App is rated 4+ and suitable for all ages. However, due to legal capacity considerations:

If you are under 18 (or the age of majority in your jurisdiction), a parent or legal guardian must read and agree to this Agreement on your behalf before use.

All paid transactions (including subscriptions and one-time purchases) must be made by a legally capable adult or with explicit guardian consent.

If you are a minor using the App, you are deemed to have obtained guardian consent.

04 Third-Party Technology & Attributions

The App integrates the following third-party components and complies with their respective licenses and terms of service:

A. Open Source Libraries & Models

MLX Framework: Licensed under the MIT License (Copyright © 2023 Apple Inc.).

Qwen Model: Licensed under its applicable open-source license (Apache 2.0 / relevant copyright notices).

B. Service Platforms & APIs

Firebase (by Google): The App uses Firebase Crashlytics for anonymous crash diagnostics to improve stability. Data processing follows Google's Privacy Policy.

Supabase: Exchange rate data in the App is powered by Supabase. Related services are subject to Supabase's Terms of Service.

Google Gemini API: If you choose to enable this feature and provide your own API Key, connections and data processing are subject to Google's AI Terms of Service.

C. Third-Party API Key Security

Key Storage: Your API Key is encrypted and stored in the system-level Keychain.

Cost Responsibility: You are solely responsible for any third-party service charges incurred through the use of your own API Key.

05 Payments & Subscription Management

Payment Processing: All paid features (including subscriptions and one-time purchases) are transacted exclusively through the Apple App Store.

Refund Policy: All billing and refund requests are handled and determined by Apple. The developer cannot directly process payments or refunds on your behalf.

Auto-Renewal:

Subscriptions automatically renew 24 hours before the end of the current period and are charged to your Apple ID account.

You can manage or cancel your subscription at any time in iOS Settings > Apple ID > Subscriptions.

Cancellation takes effect at the end of the current billing period. Fees already paid are non-refundable (except as required by Apple's policies).

If you cancel during a free trial period, you will not be charged.

06 Lifetime Purchase

Definition & Scope: A "Lifetime Purchase" grants permanent access to current paid features for the duration the App remains available on the App Store. "Lifetime" refers to the product's lifecycle, not the purchaser's natural lifespan.

End of Life: If the App is removed from the App Store due to force majeure (e.g., Apple policy changes, inability to continue the technical architecture, or developer discontinuation), we will provide 30 days' notice. After removal, users who have already downloaded the App may continue using existing on-device features, though we cannot guarantee permanent compatibility with future iOS versions.

Maintenance Obligation: A lifetime purchase does not obligate the developer to provide indefinite maintenance.

07 Prohibited Conduct

You may not attempt to reverse engineer, extract source code from, or use the on-device model logic integrated in this App for commercial purposes without permission.

The developer bears no liability for App malfunction or data breaches resulting from illegal device tampering (e.g., jailbreaking).

Dashboard Sharing Disclaimer:

By enabling the sharing feature, you agree to share the specified data with the family members you authorize.

The use, management, and any disputes arising from shared data are the sole responsibility of you and the authorized members. The developer does not intervene in disputes between family members, provide arbitration, or supply data as evidence.

You may disable or revoke sharing authorization at any time.

08 Changes & Governing Law

You and the developer acknowledge that this Agreement is solely between you and the developer, and not with Apple Inc. Apple bears no responsibility for the App or its content. Apple is not a party to this Agreement but is a third-party beneficiary, and has the right (and is deemed to have accepted the right) to enforce this Agreement against you as a third-party beneficiary.

We reserve the right to update features or terms at any time. In the event of a dispute, both parties agree that the laws of the developer's jurisdiction shall govern.
