Flagbook Terms of Service

Flag football playbook & coaching app

Last updated: 9/1/26

These terms cover your use of Flagbook, made by Mix Puppy Inc. By downloading or using the app, you agree to them.

Who This Is For

Flagbook is intended for use by coaches and adults (18 or older) organizing flag football teams. It is not directed at children, even though the roster information you enter may include the names of minors on your team.

License to Use the App

Mix Puppy Inc. grants you a personal, non-exclusive, non-transferable license to use Flagbook on devices you own or control, for organizing and coaching your own team(s). You may not copy, modify, reverse-engineer, resell, or redistribute the app itself.

Flagbook Pro (Subscription)

Flagbook is free to download and use, with a limited set of built-in plays and a small cap on how many of your own plays you can save. Flagbook Pro is an optional auto-renewing subscription that unlocks the full built-in play library, unlimited saved plays, and the Batch Duplicate, Export, and Import features. Flagbook Pro is offered in three billing options — choose whichever fits how you coach:

Your Content

Plays, rosters, lineups, and any other information you create within Flagbook are yours. As described in our Privacy Policy, this content is stored locally on your device — we don't host it, access it, or claim any ownership over it. You're responsible for keeping your own backups (via the app's Export feature, a Flagbook Pro feature) since we have no copy to restore from if it's lost.

Acceptable Use

Use Flagbook lawfully and don't attempt to disrupt, exploit, or misuse the app or its underlying code. Since Flagbook stores everything locally with no shared or public spaces, there's no user-generated content feed or community area to moderate — this section mainly covers not tampering with the app itself.

No Warranty

Flagbook is provided "as is," without warranties of any kind, express or implied. We don't guarantee the app will be error-free, uninterrupted, or fit for any particular purpose. Play design, roster management, and the in-app game clock are coaching tools, not official league timing or scoring systems — always confirm official rules and time with your league or officials.

Limitation of Liability

To the fullest extent permitted by law, Mix Puppy Inc. is not liable for any indirect, incidental, or consequential damages arising from your use of the app, including loss of data (such as plays or rosters not backed up before a reinstall or device change).

Changes to the App or These Terms

We may update Flagbook's features or these terms over time. If we make a material change to these terms, we'll update the date above. Continuing to use the app after a change means you accept the updated terms.

Termination

You can stop using Flagbook at any time by deleting the app. We may suspend or terminate access for anyone who violates these terms, though given the app's local-only, account-free design, this would in practice mean no longer distributing updates to that user rather than remotely disabling anything already installed.

Governing Law

These terms are governed by the laws of the State of New York, without regard to conflict-of-law principles.
