Terms of Service
Effective August 2, 2026
Welcome to kardfolio, operated by Marcbex LLC. These Terms of Service (“Terms”) govern your use of our credit card portfolio management service. By accessing or using kardfolio, you agree to be bound by these Terms.
If you disagree with any part of these Terms, please do not use our service.
Service Description
kardfolio is an informational service that helps you:
- Track credit card benefits and expiration dates
- Monitor signup bonus progress and spending requirements
- Organize your card portfolio with custom labels
- Receive notifications about benefit resets and expirations
Important: kardfolio is for informational purposes only and does not provide financial, investment, or credit advice. Always verify information with your card issuers and consult qualified professionals for financial decisions.
kardfolio is designed primarily for tracking credit cards and benefits offered in the United States. Availability in another country or region does not mean that kardfolio supports cards, issuers, benefits, laws, or financial products specific to that location.

- You must provide accurate and complete registration information
- You are responsible for maintaining the security of your account credentials

Data Accuracy & Limitations
You are responsible for the accuracy of all information you provide to kardfolio. We do not guarantee the accuracy, completeness, or timeliness of credit card benefit information, as terms can change without notice from card issuers.
Always verify benefit details, expiration dates, and spending requirements directly with your credit card companies before making financial decisions.
AI Assistant (Kai)
kardfolio includes an optional AI assistant called Kai. By using Kai, you agree to the following:
AI-Generated Content
- Kai's responses are generated by third-party AI models and may contain errors, inaccuracies, or outdated information
- Always verify Kai's suggestions with your card issuer before making financial decisions
- Kai is not a substitute for professional financial advice
Data Processing
- Kai accesses your kardfolio wallet data (card names, benefits, usage) to provide personalized responses
- Your conversations are processed through OpenRouter, a third-party AI routing service
- Conversation history is not saved to your kardfolio account or database. OpenRouter and selected model or search providers process requests under their applicable settings and policies.
- See our Privacy Policy for complete details
Limitations
- Kai may be unavailable due to rate limits, service outages, or technical issues
- We reserve the right to modify, limit, or discontinue Kai at any time

Intellectual Property
The kardfolio service, including its design, code, and content, is owned by Marcbex LLC and protected by copyright and other intellectual property laws. You may not copy, modify, or distribute any part of the service without written permission.
You retain ownership of the data you input into kardfolio. By using our service, you grant us a limited license to use your data solely to provide and improve the service.
Privacy
Your privacy is important to us. Please review our Privacy Policy to understand how we collect, use, and protect your information.
Service Availability
We strive to maintain high service availability but do not guarantee uninterrupted access. We may perform maintenance, updates, or modifications at any time, with or without notice.
Disclaimers & Limitation of Liability
To the maximum extent permitted by law:
- The service is provided “as is” without warranties of any kind
- We disclaim all warranties, express or implied, including merchantability and fitness for a particular purpose
- We do not warrant that the service will be error-free or uninterrupted
- We are not liable for any indirect, incidental, or consequential damages
- Our total liability is limited to the amount you paid us in the 12 months preceding the claim, or $100, whichever is greater
Termination
You may terminate your account at any time by deleting it through your account settings. Account deletion removes your active kardfolio account and data and initiates applicable provider cleanup. Certain limited records may remain as described in our Privacy Policy. We may suspend or terminate your account if you violate these Terms.
Deleting your kardfolio account does not cancel an Apple App Store subscription. You must cancel it separately through your Apple account to avoid continued billing. See our Privacy Policy for full details.
Changes to Terms
We may update these Terms from time to time. We will notify you of significant changes via email or through the service. Your continued use after changes indicates acceptance of the updated Terms.
Governing Law
These Terms are governed by the laws of the State of Washington, United States. Any dispute may be brought in a state or federal court with jurisdiction in Washington, except where applicable consumer law requires otherwise.
General Provisions
- Indemnification: You agree to indemnify and hold harmless Marcbex LLC, its officers, employees, and agents from any claims, damages, or expenses (including reasonable attorney's fees) arising from your use of the service or violation of these Terms.
- Severability: If any provision of these Terms is found to be unenforceable, the remaining provisions will continue in full force and effect.
- Entire Agreement: These Terms, together with our Privacy Policy, constitute the entire agreement between you and Marcbex LLC regarding your use of kardfolio.
- Waiver: Our failure to enforce any provision of these Terms does not waive our right to enforce that provision in the future.
