These Terms & Conditions ("Terms") govern your use of the Kakebo: Budget + AI app ("Application"), a personal-finance app created by Aurélien Ribon, an individual developer operating under the brand "Auline" ("we", "us" or "Service Provider"). The Application is distributed through the Apple App Store (iOS) and Google Play (Android). By downloading or using the Application, you agree to these Terms. Please read them before using the Application.

We grant you a personal, non-exclusive, non-transferable, revocable license to use the Application for your own personal finance tracking. All trademarks, copyrights and other intellectual property rights in the Application remain ours. You agree not to copy, modify, resell or create derivative works of the Application, nor to attempt to extract its source code, except where such restrictions are prohibited by law. You agree not to misuse the service, interfere with its operation, or use it for any unlawful purpose.

Your account is identified by your email address and has no password. You are responsible for maintaining access to and the security of the email inbox associated with your account, as access to that inbox may allow access to your account and data. Please keep your device secure and avoid jailbreaking or rooting it, which can compromise security and prevent the Application from working correctly.

The Application is free to use with optional auto-renewable subscriptions. The Pro and Max tiers unlock premium features such as voice dictation, the AI assistant and sync/sharing across devices; the Max tier includes a larger monthly AI credit. Prices are shown in-app. Billing is handled entirely by Apple (App Store) or Google (Google Play) through your store account; we never receive or see your payment details. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel your subscription at any time in your store's subscription settings; cancellation takes effect at the end of the current billing period. If prices change, the store will notify you and, where required, ask for your consent before the change takes effect.

The AI features (chat assistant, voice expense extraction and comments) are powered by third-party AI models and are provided for convenience only. AI outputs may be inaccurate, incomplete or misleading. Kakebo does not provide financial, tax, accounting, legal or investment advice, and nothing in the Application should be relied upon as such. You are responsible for verifying any important information before acting on it.

AI features are subject to a monthly usage credit (fair-use metering) that depends on your subscription tier. Once the monthly credit is reached, AI features may be temporarily limited until the credit resets. This is intended to keep the service sustainable and available to everyone.

You may generate a personal API key to let external AI tools of your choice read and modify your expense data through our API. This key grants full access to your account's data. You are solely responsible for keeping the key secret and for any third-party tools you connect with it. You can rotate (regenerate) the key in-app at any time, which invalidates the previous key.

Your financial entries and account data are stored on our servers so they can sync across your devices. We handle your personal data as described in our Privacy Policy. You can delete your account and its data from the application settings; to export your data or for any other request, contact us at support@auline.cc. You are encouraged to keep your own records of important financial information.

The Application is an independent service provided "as is" and "as available", without any uptime or availability guarantee. Some features require an active internet connection (Wi-Fi or mobile data), and we cannot be held responsible if the Application does not function fully due to lack of connectivity or an exhausted data allowance. If you use the Application over mobile data, your carrier's charges (including roaming charges) may apply and are your responsibility. If you are not the bill payer for the device, we assume you have the bill payer's permission.

We may update the Application from time to time, and operating-system requirements may change; you may need to install updates to keep using it. We do not guarantee that we will always update the Application or keep it compatible with your device's operating-system version. We may also cease providing the Application or terminate your access at any time. Upon termination, the rights granted to you under these Terms end and you must stop using the Application and, if necessary, delete it from your device.

The Application relies on third-party services that have their own terms, including OpenAI and Mistral AI (AI processing), Amazon Web Services and OVH (hosting), RevenueCat (subscription management), and the Apple App Store and Google Play (payment processing). Your use of those services through the Application is subject to their respective terms.

To the extent permitted by law, we accept no liability for any loss, direct or indirect, arising from your use of or reliance on the Application, including any reliance on AI outputs or on the accuracy of stored data.

We may update these Terms from time to time. We will post the updated Terms on this page with a new date. Please review this page regularly. Continued use of the Application after changes means you accept the updated Terms.

These Terms are governed by the laws of France.
