Terms of Service

Last updated: September 20, 2026

These Terms of Service (“Terms”) govern your use of Card Vault, Spelling Bee, and Math Flash (together, “the Apps”) and this site, operated by honestlogic.app (“we,” “us,” “the Operator”). By creating an account or using any of the Apps, you agree to these Terms. If you don't agree, please don't use the Apps.

Who Can Use the Apps

You must be able to form a legally binding contract to create an account — generally, an adult. The Apps are designed for an adult account holder (a parent, guardian, or teacher) to use on behalf of themselves and, in Spelling Bee and Math Flash, to track practice for their own children or students. Children do not create accounts of their own; if you enter a student's name or grade level, you're representing that you're authorized to do so (e.g., as their parent, guardian, or teacher).

Your Account

You're responsible for the accuracy of the information you enter and for keeping access to your sign-in email secure. Because the Apps share one sign-in across Card Vault, Spelling Bee, and Math Flash, securing or losing access to that inbox affects your session on all three.

Your Content

You keep ownership of the content you add — card photos and details, word lists, math decks, and student information. By using the Apps you give us the limited permission needed to store, process, and display that content back to you as part of operating the service (for example, sending a card photo to a vision model to identify it, or generating a practice image for a word list). We don't use your content for any purpose beyond operating and improving the Apps.

Acceptable Use

Please don't use the Apps to:

• upload content you don't have the right to use, or that is illegal, abusive, or infringes someone else's rights;
• try to access another account or another household's or classroom's data;
• interfere with or disrupt the Apps, or attempt to bypass rate limits or access controls;
• use the Apps to collect or store information about a child other than your own child or student, without appropriate authorization.

We may suspend or terminate access for use that violates these Terms.

Card Valuations Are Estimates Only

Card Vault's identification, condition assessment, and value estimates are generated automatically (including by AI models and third-party market-data sources) and are provided for informational purposes only. They are not appraisals, are not guaranteed to be accurate, and should not be relied on for insurance, tax, sale, purchase, or any other financial decision. Always verify a card's value independently, especially before any transaction.

No Warranty

The Apps are provided “as is” and “as available,” without warranties of any kind, express or implied. We don't guarantee the Apps will be uninterrupted, error-free, or that content (including AI-generated identifications, images, or audio) will always be accurate.

Limitation of Liability

To the fullest extent permitted by law, honestlogic.app is not liable for any indirect, incidental, or consequential damages arising from your use of the Apps, or for decisions made in reliance on card valuations or other automatically generated content. Our total liability for any claim relating to the Apps is limited to the amount you paid us to use them in the past twelve months (currently zero, as the Apps are free).

Changes to the Apps or These Terms

We may change, suspend, or discontinue any part of the Apps at any time. We may update these Terms; if we make a material change, we'll update the “Last updated” date above. Continuing to use the Apps after a change means you accept the updated Terms.

Termination

You can stop using the Apps and delete your account at any time. We may suspend or terminate your access if you violate these Terms.

Governing Law

These Terms are governed by the laws of the jurisdiction in which the Operator resides, without regard to conflict-of-laws principles, and any dispute will be resolved in the courts located there.
