These terms govern your use of Crew Builder (the "app"). By using the app, you agree to them.
Crew Builder recommends One Piece Trading Card Game decks based on public tournament data and the cards you tell us you own. Recommendations are not guarantees of competitive success. The app is for entertainment and learning; tournament outcomes depend on play skill, opponent decks, and matchup variance.
You are responsible for keeping your account credentials private. You may use the app anonymously (without signing in) for most features; sign-in adds cloud sync and account-deletion controls.
Card names, effect text, and images are the property of Bandai Co., Ltd., Eiichiro Oda, Shueisha, Inc., and Toei Animation. We display them under fair-use principles for non-commercial educational and informational purposes within a community deck-building tool. Crew Builder is not affiliated with, endorsed by, or sponsored by any of these entities.
Tournament data is sourced from Limitless TCG's public listings, used with appropriate attribution per their terms.
"Buy on TCGplayer" links use the TCGplayer Affiliate Program; we may earn a small commission on referred purchases at no extra cost to you.
The app is provided "as is" without warranty. We are not liable for damages arising from your use of the app, including but not limited to bad recommendations, missed tournament wins, money spent on cards we suggested, or feelings hurt by the meta.
We may update these terms; the "Last updated" date reflects the most recent change. Continued use of the app after a change means you accept the updated terms.
These terms are governed by the laws of the State of California, United States, without regard to conflict-of-law principles.
