Terms of use
Last updated: 2026-11-14
In short
- You may play Kerura for your own, non-commercial fun. You must be 13 or older.
- Cards, packs, dust, Quills and other items are part of the game and have no value in real money. Don't sell or trade them for money.
- Quills are bought with money. Packs bought with Quills are random: the odds are shown before you buy and on the odds page. They aren't offered everywhere.
- Plus is a subscription that renews until you cancel it in the store.
- Card text and images come from Wikipedia and Wikimedia Commons under free licences. They can contain mistakes.
- Your rights as a consumer always apply.
About these terms
These terms apply when you play Kerura in the app or in your browser. Kerura is provided by Sissala Jesse Juhani, sole trader, Tampere, Finland ("we"). By playing, you agree to these terms. If you don't agree, please don't play.
Our privacy policy explains how we handle personal data.
Who can play
You must be 13 or older to play. If you enter an age under 13, the game does not offer accounts, rewarded ads or purchases, and it switches off friends, gifts, trading and Peek (see the privacy policy). If you are under the age of majority where you live, ask a parent or guardian before you buy anything.
Your licence to play
We give you a personal, non-exclusive, non-transferable licence to play the game for your own non-commercial use.
The game's code, design, artwork, card frames, stats and sounds belong to us or our licensors. Card text and images from Wikipedia and Wikimedia Commons are under their own free licences (see Content from Wikipedia).
Your account
The game makes a guest account for you when it first goes online. You can add an email address and password, or Google or Apple sign-in.
- Give true information when you create an account, and keep your password secret. You are responsible for what happens under your account.
- Other players see your display name. Names with contact details, or that are offensive or misleading, are refused or hidden, and we may reset them.
- A guest account can't be recovered if you delete the app, clear your browser's data or sign out. An account with a sign-in method can be used on another device.
- You can delete your account in the game (Settings, Your data, Delete online profile). Its cards, Quills, purchases and everything else stored with it are deleted at once, and we can't restore them. Deleting an account doesn't cancel a subscription: cancel it in the store.
- An account that nobody used for 24 months is deleted with everything on it, unless a Google or Apple sign-in is linked to it.
- We may block an account that breaks these terms (see Playing fair).
Virtual items
Cards, packs, dust, Pack Points, Quills and other items in the game are part of the game. They are licensed to you, not sold, and they have no value in real money. You can't cash them out, and you can't sell, trade or transfer them for money or anything else of value outside the game. Quills can't be given to other players. Inside the game you can give a duplicate card to a friend and trade cards with other players; neither involves a payment.
Our server keeps the records of your items: your collection and balances are stored on your account, and the game shows what the server says. We may change how items work, for example to fix bugs, to balance the game or to correct an error.
Before you pay for anything, you see exactly what you get.
Quills and packs
Quills are the game's paid currency. You buy them with money in the app, in bundles. The price in your store's currency is shown before you pay, and the game shows what each Quills price is worth in money. Quills have no cash value, and they can't be exchanged for money or given to other players.
You spend Quills on packs and on fixed items: cards from the daily shelf, commissioned cards, finishes and finishing a set. Their prices in Quills are shown in the game before you buy.
A pack bought with Quills holds random cards. The odds of each rarity, the guarantees and the prices are shown before every purchase and on the odds page. Packs bought with Quills aren't offered in Belgium, in China, when your country is unknown, to players under 16, or in Brazil to players who haven't said they are 18 or over. Where they aren't offered, the shop sells only fixed items. In Belgium, Brazil and where your country is unknown, a rewarded ad gives dust instead of a pack.
A refund of a Quills purchase through the store takes those Quills back. If you have already spent them, your balance can go below zero, and you can't spend Quills until it is covered.
Purchases and subscriptions
Purchases are made through Google Play or the App Store, and their terms apply as well. The price is shown in the store before you pay.
- Plus is a subscription, monthly or yearly. It gives one card a week from your wishlist (not Mythic), 5 Quills a day, an unlimited wishlist and Expeditions. It renews automatically until you cancel. Cancel in your Google Play or App Store subscription settings at least 24 hours before the renewal date. You keep Plus until the end of the period you paid for.
- A free trial, if offered (7 days on the yearly plan), is for first-time subscribers, as decided by the store. If you don't cancel before the trial ends, the subscription starts and you are charged.
- Expeditions, style items (card frames, card backs, binder themes), the supporter bundle, the starter bundle and Curator Pass seasons are one-time purchases. The starter bundle can be bought once per account. A Curator Pass is for one season: it adds a second fixed reward to each level of that season's pass, and every reward is listed in the game before you buy. Levels come from playing and can't be bought. When you buy, you get the rewards of the levels you have already reached; levels you don't reach before the season's end date aren't given. Rewards you have taken stay yours. Restore purchases brings back your style items and Expeditions on another device with the same store account.
- Refunds are handled by Google Play or Apple under their refund policies. We can't refund store purchases ourselves. When a purchase is refunded, what it gave is taken back: the Quills, the item or Plus.
- Digital content is delivered right after purchase. If you live in the EU, you agree to immediate delivery and acknowledge that you lose the 14-day right of withdrawal once delivery has started. This doesn't affect your rights if something you bought doesn't work.
Rewarded ads
Some rewards can be earned by choosing to watch an ad: an extra pack (at most 3 a day), one revive in a run, or doubled Pack Points after a run. Watching ads is optional, and an ad plays only when you tap to watch one. The reward is paid once the ad is confirmed as watched to the end. Rewards from ads follow the same rules as other items. Faking ad views is not allowed.
Content from Wikipedia
Cards show shortened excerpts of Wikipedia articles under the Creative Commons Attribution-ShareAlike 4.0 licence, and images from Wikimedia Commons under their own free licences. Each card credits and links to its source; see Credits. You may reuse that content under those licences.
Wikipedia is written by volunteers and can be incomplete or wrong. We don't check or change the text, so don't rely on cards as advice of any kind.
If a card is offensive or wrong, or it is about you, use the card removal page.

Playing fair
Please don't:
- cheat, use bots, or exploit bugs to get items or scores (please report bugs instead);
- copy, reverse engineer or modify the game, except where the law allows it;
- scrape or overload our servers, or try to get around their security;
- use the game or its share links to harass or mislead other people;
- sell items, progress or services related to the game.
If you break these rules, we may remove your results from shared features or block your access to our servers.
Warnings, suspension and ending
If you break these terms or the law, or put other players at risk, we may warn you, remove your results from shared features, take back items you got by cheating or by exploiting a bug, suspend or close your account, or block access to our servers. We tell you why when we can, and you can answer us at the contact address below.
You can stop playing and delete your account at any time. We may stop offering the game or parts of it (see Changes to the game). Terms that by their nature continue, such as the limits on liability and the governing law, stay in force after an account ends.
Changes and availability
We keep improving the game, so features, cards and rules change. Some features need an internet connection. We may stop offering the game or parts of it. If that affects something you paid for, we will tell you in advance and do what the law requires.
Liability
The game is provided "as is" and "as available". Features need an internet connection, servers can be down, and we don't promise that the game will always work, be free of errors, or that scores, cards and accounts will never be lost.
Limit. To the extent the law allows, our total liability to you for all claims about the game is limited to the greater of (a) what you paid us in the 12 months before the claim arose and (b) EUR 100. We are not liable for indirect or consequential losses, for lost virtual items (they have no cash value), for game data lost on your device, or for problems caused by your device, your connection, the app stores or other companies' services.
What this doesn't limit. Nothing in these terms limits liability for intent or gross negligence, for death or personal injury, for defects the law makes us answerable for, or any other liability the law doesn't allow us to limit. Nothing limits your rights as a consumer under the mandatory law of the country where you live.
If you got the app from the App Store
These terms are between you and us, not Apple. Apple is not responsible for the app or its content, has no duty to provide support for it, and is not responsible for claims about it, such as product liability, legal compliance or intellectual property. If the app fails to meet a warranty that applies, you can tell Apple, and Apple will refund the purchase price, if any. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them. Where these terms don't cover something, Apple's standard licence agreement applies.
Law and disputes
Finnish law applies, but you keep the protection of the mandatory consumer laws of the country where you live. If something goes wrong, please contact us first. Consumers in Finland can take a dispute to the Consumer Disputes Board (kuluttajariita.fi); consumers elsewhere in the EU can use their own country's consumer bodies or courts, and the EU's online dispute resolution points where available.
If you use the game for business, or live outside the EU and the United States, disputes go to the district court of Pirkanmaa, Finland.
If you live in the United States
This section applies only if you live in the United States. It doesn't apply to anyone else, and it doesn't apply if you are under 18.
- Talk to us first. Write to the contact address below and give us 30 days to resolve a problem before you start a claim.
- Individual claims only. You and we may bring claims only for yourselves, and not as a plaintiff or class member in a class, collective or representative action.
- Small claims. Either of us may bring an individual claim in small claims court.
- Arbitration. Any other dispute is settled by binding individual arbitration under the American Arbitration Association's Consumer Arbitration Rules, instead of in court before a judge or jury. We pay the filing, administrator and arbitrator fees for claims under USD 10,000, except where the arbitrator finds a claim frivolous. The arbitrator applies these terms.
- Opting out. You can opt out of arbitration and the class waiver within 30 days after you first accept these terms, by writing to the contact address below with the subject "Opt out".
- If the class waiver is found unenforceable, the arbitration clause does not apply and the dispute goes to court.
General
These terms, together with the privacy policy, are the whole agreement between you and us about the game. If a part of them is found invalid, the rest stays in force. We may transfer the game and these terms to another company; you may not transfer your account. We are not responsible for delays or failures caused by events outside our control, such as outages of the internet, the stores or hosting providers. If we don't enforce a right right away, we can still enforce it later. If a translation differs from the English text, the English text counts.
Changes to these terms
We may update these terms. We change the date at the top, and for important changes we will tell you in the game before they take effect. If you keep playing after that, the new terms apply.
