Terms of Service
Last updated: December 6, 2025
These Terms of Service ("Terms") govern your access to and use of the Catsle application ("App" or "Service") provided by CatBrains ("we," "us," or "our"). By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree to these Terms, do not use the App.
1. Acceptance of Terms
By creating an account or using the Service, you represent that you are at least 13 years of age (or the minimum age required in your jurisdiction) and have the legal capacity to enter into these Terms. If you are between 13 and 18 years of age (or the age of majority in your jurisdiction), you represent that your parent or legal guardian has reviewed and agreed to these Terms on your behalf. We may require verification of parental consent and reserve the right to suspend or terminate accounts of minors who cannot provide such verification. If you are using the Service on behalf of an organization, you represent that you have the authority to bind that organization to these Terms.
2. Description of Service
Catsle is a personal expense tracking and budgeting application that allows you to manually record your income, expenses, and financial transactions. The App stores your data on our servers to enable synchronization across your devices. The financial data you enter is self-reported and not connected to any bank accounts, payment cards, or financial institutions. We do not verify the accuracy of any data you enter.
3. Account Registration
To use certain features of the Service, you must create an account by providing accurate, current, and complete information. You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You must notify us immediately of any unauthorized access or use of your account. We reserve the right to suspend or terminate accounts that contain false or misleading information.
4. Account Sharing Prohibition
Your account and any purchased licenses are for your personal use only. You may not share, lend, sell, transfer, or otherwise provide access to your account credentials or license to any other person or entity. Each user must maintain their own separate account. Violation of this provision may result in immediate account suspension or termination without refund. We reserve the right to monitor usage patterns to detect potential account sharing and take appropriate action.
5. Trial Period
New users may be granted a trial period during which they can access the Service without purchasing a license. The duration and features available during the trial period are determined at our sole discretion and may be changed or discontinued at any time without notice. Upon expiration of the trial period, continued access to the Service requires the purchase of a license.
6. License and Payment
The App offers a lifetime license available for purchase through the respective platform's in-app purchase system (e.g., Apple's In-App Purchase for iOS). The lifetime license grants you access to the basic features of the Service for as long as the Service remains available, without additional recurring fees. "Lifetime" refers to the operational lifetime of the Service, not the lifetime of the user. All payment transactions are processed by the platform provider, and we do not collect or store your payment information. Prices are subject to change, but changes will not affect licenses already purchased. We reserve the right to introduce additional features or services that may require separate purchase.
7. Refunds
All purchases are processed through the respective platform provider (e.g., Apple's App Store for iOS) and are subject to that provider's refund policies. We do not directly process refunds. For refund requests, please contact the platform provider through which you made the purchase. We are not obligated to provide refunds except as required by applicable law.
8. Multi-Platform Access
While the Service is currently available on iOS devices, we may expand to additional platforms in the future. If you access the Service from multiple platforms, your data will be synchronized across devices. Different platforms may have different payment processors and license terms. Licenses purchased on one platform (e.g., Apple App Store) may not automatically transfer to other platforms (e.g., Google Play Store). We are not responsible for platform-specific restrictions, policies, or technical limitations imposed by third-party app stores or operating systems.
9. Future Subscription Services
While the Service currently operates on a lifetime license model, we reserve the right to introduce subscription-based services, premium features, tiered pricing, or additional paid services in the future. Existing lifetime license holders will retain access to the core features available at the time of their purchase, but may need to purchase separate subscriptions or pay additional fees to access new premium features or services. We may change subscription terms, subscription fees, feature availability, and service offerings at any time on a go-forward basis. If we introduce subscription services, we will provide advance notice of such changes. Continued use of subscription-based services after price or term changes constitutes acceptance of the new pricing and terms.
10. License Restrictions
Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to use the App for your personal, non-commercial purposes. You may not: • Copy, modify, or distribute the App. • Reverse engineer, decompile, or disassemble the App. • Rent, lease, lend, sell, or sublicense the App. • Remove or alter any proprietary notices. • Use the App for any unlawful purpose. • Circumvent any access control or usage restrictions.
11. User Responsibilities
You are solely responsible for the accuracy and legality of all data you enter into the App. You agree not to use the Service to store or transmit any content that is illegal, harmful, threatening, abusive, defamatory, or otherwise objectionable. You are responsible for maintaining appropriate backups of your data.
12. Prohibited Conduct
You agree not to: • Violate any applicable laws or regulations. • Infringe upon the rights of others. • Interfere with or disrupt the Service or servers. • Attempt to gain unauthorized access to any part of the Service. • Use automated means to access the Service without our permission. • Transmit viruses, malware, or other harmful code. • Impersonate any person or entity. • Engage in any activity that could damage, disable, or impair the Service. • Use the Service for competitive analysis or to build a competing product.
13. Abuse and Misuse
We reserve the right, at our sole discretion and without prior notice, to suspend, restrict, or permanently terminate your access to the Service if we determine that you have engaged in abusive, fraudulent, or harmful conduct. This includes, but is not limited to: • Exploiting bugs, vulnerabilities, or system errors. • Manipulating or abusing promotional offers, trial periods, or referral programs. • Engaging in any activity that places excessive burden on our infrastructure. • Using the Service in a manner that negatively affects other users. • Any other conduct we deem to be abusive or contrary to the spirit of these Terms. Such action may be taken without refund and without liability to you.
14. Security and Unauthorized Access
While we implement reasonable security measures to protect your data, no system is completely secure. We are not liable for any unauthorized access to your account or data resulting from: • Hacking, cyberattacks, or other malicious activities by third parties. • Your failure to maintain the confidentiality of your account credentials. • Security vulnerabilities in your device or network. • Phishing, social engineering, or other deceptive practices targeting you. • Circumstances beyond our reasonable control. You acknowledge and accept these inherent risks of using internet-based services. We strongly recommend using strong, unique passwords and enabling any available security features.
15. Intellectual Property
The App and its original content, features, and functionality are owned by CatBrains and are protected by international copyright, trademark, patent, trade secret, and other intellectual property laws. Our trademarks and trade dress may not be used without our prior written consent. You retain ownership of the data you enter into the App, but grant us a limited license to store, process, and display that data as necessary to provide the Service.
16. User Contributions and Feedback
If you provide us with any feedback, suggestions, testimonials, reviews, ideas, bug reports, or other submissions ("Contributions"), you grant us a worldwide, perpetual, irrevocable, royalty-free, transferable, sublicensable license to use, reproduce, modify, adapt, publish, translate, create derivative works from, distribute, and display such Contributions for any purpose, including marketing, promotional, development, and commercial purposes. We are not obligated to use your Contributions, compensate you for them, maintain their confidentiality, or attribute them to you. You represent and warrant that you own all rights to your Contributions and that they do not violate any third-party rights, including intellectual property, privacy, or publicity rights.
17. Third-Party Integrations and Applications
The Service may allow integration with third-party applications, services, or APIs in the future. We do not endorse, control, or assume responsibility for any third-party integrations. Your use of third-party integrations is at your own risk and subject to their respective terms and privacy policies. Any third-party applications that access your Catsle data must clearly display: "This application is not officially supported or endorsed by CatBrains or Catsle." We are not responsible for the security, functionality, or data practices of third-party applications. You acknowledge that granting access to third parties may expose your data to unauthorized use, and you assume all risks associated with such integrations.
18. Service Availability and Modifications
We strive to provide reliable service but do not guarantee uninterrupted or error-free operation. We may modify, suspend, or discontinue the Service (in whole or in part) at any time, with or without notice. We will endeavor to provide reasonable notice of significant changes when practicable. In the event of permanent service discontinuation, we may, at our sole discretion, provide data export options. However, we are not obligated to provide data export functionality, and data export may be subject to technical limitations, format restrictions, or time constraints. You are responsible for maintaining your own backups of important data. Lifetime license holders acknowledge that the license grants access only for the duration of service operation, and no refunds will be provided upon service modification or discontinuation.
19. Account Termination
You may terminate your account at any time by contacting us or through the account settings in the App, if available. We may suspend or terminate your account immediately, without prior notice, if we believe you have violated these Terms, engaged in fraudulent activity, or for any other reason at our sole discretion. Upon termination, your right to use the Service will immediately cease, and we may delete your account data in accordance with our Privacy Policy. Termination does not entitle you to a refund.
20. Disclaimer of Warranties
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, THAT DEFECTS WILL BE CORRECTED, OR THAT THE SERVICE IS FREE OF VIRUSES, MALWARE, OR OTHER HARMFUL COMPONENTS. YOU ASSUME ALL RESPONSIBILITY FOR SELECTING THE SERVICE TO ACHIEVE YOUR INTENDED RESULTS AND FOR THE USE AND RESULTS OBTAINED FROM THE SERVICE. YOU ARE SOLELY RESPONSIBLE FOR IMPLEMENTING SUFFICIENT ANTIVIRUS PROTECTION, SECURITY MEASURES, AND DATA BACKUP PROCEDURES ON YOUR DEVICES. THE FINANCIAL RECORDS, CALCULATIONS, AND INSIGHTS PROVIDED BY THE APP ARE FOR PERSONAL REFERENCE ONLY. YOU SHOULD NOT RELY UPON THEM FOR TAX, LEGAL, INVESTMENT, OR PROFESSIONAL FINANCIAL PURPOSES. WE ARE NOT FINANCIAL ADVISORS AND DO NOT PROVIDE FINANCIAL ADVICE. ANY RELIANCE YOU PLACE ON INFORMATION PROVIDED BY THE SERVICE IS STRICTLY AT YOUR OWN RISK.
21. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL CATBRAINS, ITS DIRECTORS, EMPLOYEES, PARTNERS, AGENTS, SUPPLIERS, OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION LOSS OF PROFITS, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, RESULTING FROM: • YOUR ACCESS TO OR USE OF OR INABILITY TO ACCESS OR USE THE SERVICE. • ANY CONDUCT OR CONTENT OF ANY THIRD PARTY. • UNAUTHORIZED ACCESS, USE, OR ALTERATION OF YOUR DATA. • ANY ERRORS OR OMISSIONS IN THE SERVICE. OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING FROM OR RELATING TO THE SERVICE SHALL NOT EXCEED THE AMOUNT YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR TEN US DOLLARS ($10), WHICHEVER IS GREATER. THESE LIMITATIONS APPLY REGARDLESS OF THE LEGAL THEORY AND EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.
22. Indemnification
You agree to defend, indemnify, and hold harmless CatBrains and its officers, directors, employees, contractors, agents, licensors, and suppliers from and against any claims, damages, obligations, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising from: • Your use of the Service. • Your violation of these Terms. • Your violation of any third-party rights. • Your data or content submitted through the Service. This obligation survives termination of these Terms and your account.

You agree to submit to the exclusive jurisdiction of the courts located in the Republic of Korea for the resolution of any disputes arising from these Terms or the Service.

26. Severability
If any provision of these Terms is found to be unlawful, void, or unenforceable, that provision shall be deemed severable and shall not affect the validity and enforceability of the remaining provisions.
27. Waiver
Our failure to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. Any waiver must be in writing and signed by us to be effective.
28. Entire Agreement
These Terms, together with our Privacy Policy and any other legal notices or agreements published by us, constitute the entire agreement between you and CatBrains regarding the Service and supersede all prior agreements and understandings.

You can opt out of promotional communications at any time by following the unsubscribe instructions in such emails or by contacting us. Opting out of promotional emails will not affect operational communications related to your account or the Service.
31. Changes to Terms
We reserve the right to modify these Terms at any time. We will notify you of material changes through the App or via email when practicable. Your continued use of the Service after any changes constitutes your acceptance of the revised Terms. If you do not agree to the new Terms, you must stop using the Service.
