Terms of use

The short version

Deckhand is a tool for organising a card collection you already own and finding decks you can build from it. Use it for that. Your data is yours and you can take it out or delete it at any time. The service is provided as it is, and it may change or stop.

Your account

• You must be at least 13 to have an account.
• You are responsible for keeping your password to yourself. An account is for one person; do not share it.
• An account may be closed if it is used to attack the service or other people.

Acceptable use

Do not try to break the service, overload it, scrape it, reach other people’s data, or work around the limits of your plan. The card data and decklists are provided under the terms of their sources, which are credited on every page; do not redistribute them.

Your data

What you add — your collection, the decks you save or write — stays yours. Deckhand uses it only to answer your own questions in the app and never sells it or shares it. You can export it and you can delete it, from inside the app, at any time. The privacy policy is the full statement of what is stored and why.

One thing that page says and this one should not leave out: on a free account nobody has used for 30 days, the decks you have saved or marked as built may be removed. You are emailed a week before it happens, and signing in once keeps them. Using Deckhand resets that clock and you do not have to sign in again for it to count. Your collection and the decks you wrote yourself are never removed this way, paid accounts are never subject to it, and everything can be exported at any time.

Plans and payment

A free account keeps up to 500 distinct cards. Paid plans cover the size of your own collection and what is kept around it; browsing cards and decks stays free and needs no account. Prices are shown on the pricing page before you pay, in US dollars, and can change with notice. Plans are bought on this website: the phone app sells nothing and, on the United States App Store only, may show a link to the pricing page. Payment is taken by Stripe, who are the merchant of record and collect any sales tax or VAT due; Deckhand never sees your card.

A paid plan renews until you cancel it, which you can do at any time from your account page; cancelling keeps the plan until the end of the period already paid for. Deleting your account is different: it cancels the subscription at that moment, and the rest of the paid period is not refunded — the delete button says so before you press it. A collection larger than your plan’s limit is never removed: every card in it stays yours to see, change, remove and export, and only adding new cards waits until it is under the limit again or the plan is raised.

Prices and estimates

Every price in Deckhand is an estimate from a third-party market feed and some cards have none. It is there to give a sense of what finishing a deck costs, not as a quote, and Deckhand sells no cards. Where a card has been printed more than once, the figure is for one printing, not for the particular copy you own or the one you would be sold: for Yu-Gi-Oh! it is a typical printing, and for Magic the cheapest non-foil printing. A rarer printing of the same card can cost many times it, so a collection’s estimated value is not an appraisal. Prices are refreshed in batches rather than continuously. The dashboard, My Collection, My Decks, the Deck Finder and each deck’s and card’s own page say how long ago that was. Read it rather than assuming a figure is from today.

Deck legality

A deck page checks a deck’s section sizes, how many copies of each card it runs and, against a Forbidden and Limited or banned and restricted list, whether any of its cards are on one. Which list is your choice: the page offers the lists Deckhand holds for that game and you pick one, including no banlist at all. It opens on the list for the format the deck is labelled with, where one is held. Whatever you pick, the page says which list it used and the date that list was current as of, because a deck legal against one month’s list may not be legal against the next.

The deck lists — My Decks, the Deck Finder and Deck Search — mark each deck beside its format with what its deck page says before you choose anything: the list for the format the deck is labelled with, and its points where that format has them. A tick means the page found no rule broken, a warning sign that it found one. There is no mark at all when Deckhand holds no list or points for the deck’s format and the deck breaks none of the rules it can still check (its size and copy limits); a deck that breaks one of those gets the warning sign all the same. Opening the mark says which list it used, as of when, what it found and what it did not check. A Yu-Gi-Oh! deck you wrote without choosing a format is judged as a TCG deck, exactly as its page judges it. The mark is the page’s verdict, so everything below about that verdict applies to it too.

The lists held are other people’s publications, named on the page when they are used. For Yu-Gi-Oh! they are the current TCG list, the OCG list and the Goat format list as YGOPRODeck publishes them, and four frozen historical lists kept as files in Deckhand itself: the Edison format list of March 2010, the Tengu format list of September 2011, the Wind-Up format list of September 2012 and the HAT format list of April 2014. For Magic they are the banned and restricted list and the card pool of each format the corpus labels decks with — Standard, Pioneer, Modern, Legacy, Vintage, Pauper, Commander, Duel Commander, Brawl and Premodern — as Scryfall publishes them. A deck is only ever offered its own game’s lists.

A Genesys deck is checked a second way, because Genesys bans nothing and instead gives cards a point cost and the deck an allowance. The page counts what the deck spent — every copy, over the main, extra and side decks together — and says so with the date those costs were current as of, and it says “at least” whenever the list has no cost for one of the deck’s cards, because a total we could not finish is a floor rather than a measurement. Which points to count is your choice too: a second control beside the first offers every points system Deckhand holds costs for, so you can ask what a deck of any format would cost under Genesys — the page then says so, and still judges the deck by its own format’s sizes and copy limits — and it lets you decline the check, which names the allowance as not checked rather than reporting a deck as inside it. Genesys is the only points system Deckhand holds costs for.

The page also says what it did not check, and there is always something: which cards exist in the TCG at all, the Trinity point budget (no costs are held for it), the Domain and Common Charity formats (no list is held for them, and the page says so), a Commander deck’s colour identity, and anything an event adds on top of the printed rules. Choosing no banlist, or declining the points, is reported the same way — the sizes and copy limits are still checked and what you declined is named as not checked, never as passed. Where no list is held, nothing is guessed. “No rule violations found” means exactly that and nothing more — it is not a statement that a deck is legal to play at any event, and the lists it was checked against can be wrong or out of date. Before you take a deck anywhere that matters, check it against that event’s own rules yourself.

The scanner, and what you enter

The scanner reads what the camera can see and asks when it is unsure, but it is software: it can misread a name, and a misread card goes into your collection, from which every number on the site is computed. You are responsible for checking what landed — the review screen and My Collection are there for that — and for whatever you type or paste in. Deckhand is not responsible for a card bought, traded or sold, or a deck built, on the strength of a count that was wrong.

The playtest

The playtest is a sandbox, not a referee. The rules engine and the card scripts it plays are open-source projects credited on the playtest page, which Deckhand does not control: a card can be scripted differently from its printed ruling, an interaction can resolve differently from how a judge would rule it, a card the engine cannot play is named before the duel starts and left out, and no banlist is applied. Retro formats play on today’s card text except where the page says a card plays its period text. The bot is software and plays as well as it plays. Nothing that happens in a playtest is a ruling, and Deckhand is not responsible for a tournament result, a trade or a purchase made on the strength of one.

Data from other people

Card data, images, prices and decklists come from other people’s services, credited on every page. Deckhand does not control them and does not promise they are accurate, complete or available: a card can be mislabelled at the source, a decklist can be wrong or out of date, and a source can change or go away. Prices in particular are estimates, as Prices and estimates says above.

Availability

Deckhand runs on one server, looked after by one person. There is no promise of uptime: it will sometimes be down for maintenance or for reasons nobody planned, usually without notice, and a scan you have not yet reviewed or a page half-loaded can be lost when it is. What you have saved is not — it is stored apart from the server and is there when the service comes back.

Liability

Deckhand is provided “as is” and “as available”, without a warranty of any kind — not that it is accurate, not that it is fit for any particular purpose, and not that it is free of faults.

To the extent the law allows, Deckhand is not liable for any loss arising from using it or from being unable to use it. That includes indirect or consequential loss, data you had not exported, cards bought, traded or sold on the strength of a number it showed, and a deck refused at an event. Where liability cannot be excluded, it is limited to what you paid for Deckhand in the twelve months before the claim.

Nothing in these terms limits a liability the law does not allow to be limited, and nothing takes away a right you have as a consumer that cannot be given up.

Changes and ending

These terms may change; the date above says when. A material change will be announced in the app before it applies. You can stop using Deckhand and delete your account at any time. Deckhand may suspend or close an account that breaks these terms, and may end the service with reasonable notice, giving you time to export your data.
