This is a courtesy translation. The service is operated from Poland and the Polish version is the binding one; in case of any discrepancy, the Polish text prevails.

1. What Craterborn is
Craterborn is a free browser game. The service is provided by Michał Sikora, Aleja Reymonta 21 m. 255, 01-840 Warsaw, Poland (the “Service Provider”), contact: contact@craterborn.com.
To play you need a browser with WebGL support and an internet connection. You do not have to provide any personal data — choosing a character name is enough.
2. Your account
- The Service Provider recognises the account by its character code — a random string the game stores in your browser.
- Whoever has the code has the account. Do not share it with anyone. The Service Provider is not liable for the consequences of disclosing it.
- You may link the account to an e-mail address — you will then recover it even after clearing your browser. The Service Provider recommends doing so.
- An account with no linked address and no saved code is unrecoverable. The Service Provider has no way of confirming that it was yours.
- One person may hold several accounts. They must not be used to evade bans or the rules of the game.
3. Rules of conduct
In the game you must not:
- use software that alters how the game works, bots or automation;
- exploit bugs for advantage instead of reporting them;
- disrupt the server or interfere with other people's play;
- use names that are offensive, obscene, impersonate other people or infringe the rights of others;
- attempt unauthorised access to other people's accounts.
In the chat you additionally must not (from 27 September 2026):
- insult, harass or intimidate other players;
- post obscene, hateful or sexual content, or content inciting violence or unlawful acts;
- flood the chat with repeated messages, advertise other services or post links to phishing sites;
- disclose personal data — your own or anyone else's;
- ask others for their character code or impersonate game staff.
Neither the Service Provider nor any game staff will ever ask you for your character code — not in the chat and not by e-mail. When a character is created, the game rejects obscene names and names reserved for game staff.
Reporting and blocking. Messages are not reviewed before they are sent. Report abuse in the game: tap the player's name in the town chat or type it in Settings → Other players. The report includes that player's recent messages you saw — but only those the server actually relayed from them within the last 15 minutes. You can also report abuse to the contact address. You can block any player: you will not see their messages or party invitations.
Penalties. Reports are reviewed by the Service Provider. For breaching these rules the Service Provider may temporarily block your chat, suspend the account for a set time or permanently, or delete the account. You will learn about a restriction in the game — its type, duration and reason. A suspended account does not hold places in the leaderboards and does not receive weekly rewards. If you believe it is a mistake, write to the contact address and the Service Provider will review the matter again. For serious breaches the Service Provider may act without warning.
4. Availability of the service
The game is in testing. The Service Provider does not guarantee continuous availability or that progress will be preserved. The server is taken down at times, and data may be wiped during larger changes. The Service Provider will announce planned progress wipes in the game.
The Service Provider reserves the right to change the rules, balance and content of the game, and to suspend or discontinue the service. Should the Service Provider shut the service down for good, it will give at least 30 days' notice.
5. In-game currency and items
Currency, items and characters exist only inside the game. They are not your property and have no value outside the game. They must not be sold, traded or transferred outside the game for money or other benefits.
Loot gathered in the crater reaches your stash only once you extract. If your character dies or does not get out before the crater closes, all loot you were carrying is lost and other players may take it. Items that do not fit in the stash are lost too. These are the rules of the game, not a bug, and such losses are not restored.
If the connection drops, your character stays in the crater for 30 seconds and waits for you to return — it is not invulnerable during that time. If you do not return to the game in time, the run ends just like abandoning it and the loot you were carrying is lost.
5a. Gems and the season pass
Gem sales have been live since 4 October 2026. On the game's website gems are sold by Sold through Link (a Stripe company); in the app from Google Play (currently in closed testing) — by Google. Details in section 5c.
Gems are a currency you buy with money or earn in the game:
- during the Gem Rush — every day from 18:00 to 21:00 Polish time each defeated elite drops 1 gem and the boss drops 2;
- by watching an ad to the end, when ads are available — 5 gems per ad, up to 5 ads a day;
- for a weekly leaderboard podium — when the week ends (Monday 00:00 Polish time), the top three places on the loot, extracted and bosses boards get 30, 20 and 10 gems; an equal score is an equal place and an equal reward. The kills board gives no gems. From 11 November 2026 a defeated boss counts on the bosses board only for party members who, at the moment it falls, are on the same floor of the crater within 30 m of it.
Gems found in the crater count only once you extract: if you die, they stay in your cairn and another player may take them, just like loot. Gems earned in the game are not a purchase and are not refundable. The Service Provider may change the hours and the amounts like any other game rule (section 4).
Gems buy only the season pass, which grants character appearance and returns part of the gems. Gems cannot buy anything that affects gameplay — no gear, stats, upgrades or crafting materials.
The exception is the pass for the September 2026 season, which runs until 5 November 2026: it also grants Marks and crafting materials, as its reward track shows. From the November 2026 season the pass grants only character appearance and gems.
The pass runs for one season — from the 6th day of a month to the 5th day of the next month inclusive, Polish time. A season may be extended; an extension does not reset progress or shorten the pass. Levels come from daily contracts. When the season ends progress resets, but everything you have unlocked stays yours forever — as do unspent gems, which do not expire.
Pass rewards are claimed by you. Rewards you have earned but not claimed by the end of the season are moved to your stash automatically at the start of the next season. Levels do not carry over to the next pass.
The pass cannot be bought when too little time is left in the season to earn its outfit.
5b. Right of withdrawal and consent to immediate performance
Buying gems or the pass is the supply of digital content not supplied on a tangible medium.
As a consumer you generally have the right to withdraw from the contract within 14 days without giving a reason. For digital content that right is lost if performance began with your express prior consent and with your acknowledgement that you thereby lose the right of withdrawal (Art. 16(m) of the Consumer Rights Directive 2011/83/EU, implemented in Poland by Art. 38(1)(13) of the Consumer Rights Act).
Before every purchase the Service Provider therefore asks you to tick a statement reading:
"I request immediate delivery of the digital content and acknowledge that I lose my right of withdrawal once it has been delivered."
Without that consent the purchase does not go through.
The consent concerns the right of withdrawal only. It does not limit your rights where the digital content does not conform to the contract — if the gems or the pass do not work as described, you may complain under section 8.
Purchases made through a platform store (App Store, Google Play) are settled by that platform and its refund rules take precedence there.
5c. Who sells and who processes the payment
The seller depends on where you buy. On the website gems are sold by Sold through Link (a Stripe company); in the app from Google Play they are sold by Google. In both cases the purchase contract is with that seller, not with the Service Provider, and that seller is responsible for taxes, invoices and refunds. The game itself is run by the Service Provider.
On the website
Gems are sold by Sold through Link, LLC — a Stripe company — acting as the merchant of record. This means your purchase contract for the gems is with them, not directly with the Service Provider, and they are responsible for VAT and sales tax, and for handling refunds and payment disputes.
You enter your card details on the seller's payment page and they never reach the Service Provider in any form — the Service Provider has no access to them and does not store them.
Gem prices are set in Polish złoty (PLN). The checkout may show the amount converted into your country's currency at the rate of the moment of purchase — the amount shown in the checkout before you pay is the binding one. Euro amounts in the English version of the game are estimates. If your card's currency differs from the payment currency, your bank may add its own conversion fee.
On your card statement the charge appears with the prefix LINK.COM*, not as "Craterborn". If you do not recognise a charge, that is what it is.
Receipts and invoices are sent by the seller. Your purchase history and refund requests live at link.com, under their refund policy (support.link.com/questions/sold-through-link-refunds); a refund may be granted within 60 days of the purchase, even where the Service Provider's own rules would be stricter.
A refund takes the gems back. When the seller refunds your payment, the same number of gems leaves your account. If you have already spent them, the balance drops to zero and no further — the Service Provider reviews the rest by hand. Things bought with gems before the refund may be reversed.
The game itself is run by the Service Provider — details in section 1. Complaints about how gems and the season pass behave IN GAME go to the Service Provider; anything about payment, invoices or refunds goes to the seller.
Gems are credited automatically, usually within seconds of the payment clearing. With delayed payment methods (e.g. bank transfer) delivery follows once the funds arrive. If gems have not appeared an hour after payment, write to the contact address with the date of purchase — the store's payment confirmation is enough for the Service Provider to find the transaction.
In the app from Google Play
In the app installed from Google Play, gems are sold by Google Commerce Limited (Ireland). Your purchase contract is with Google, Google issues the purchase confirmation, and Google is responsible for taxes and for handling refunds. Google Play's rules then take precedence over section 5b.
You enter your payment details in Google's dialog and they never reach the Service Provider in any form. On your statement the charge appears with a Google prefix followed by CRATERBORN. If you do not recognise a charge, that is what it is.
Prices in the app are set by Google per country and shown in your own currency — the amount shown in the purchase dialog before you pay is the binding one. The estimates used in the website version do not apply there.
A refund takes the gems back. When Google refunds a purchase, the same number of gems is removed from the account. If you have already spent them, the balance drops to zero and no lower — the remainder is reviewed by hand. Things bought with gems before the refund may be reversed.
Complaints about how gems and the season pass behave IN GAME go to the Service Provider; anything about payment, invoices or refunds goes to Google.
6. Leaving
You may stop using the game at any time. You can delete the account in the game settings, on the account deletion page (also without the game, with your character code) or by writing to the contact address. Deletion is irreversible.
7. Liability
The service is free and provided as is. To the extent permitted by law the Service Provider is not liable for loss of in-game progress, downtime, or damage arising from use of the game.
The limitation above does not exclude liability for damage caused intentionally, nor any liability that cannot be excluded by law — in particular towards consumers.
8. Complaints
Send complaints to the contact address above. The Service Provider will answer within 14 days. As a consumer you may also use out-of-court dispute resolution, including mediation at the regional Trade Inspection authorities in Poland, or the dispute resolution bodies available in your own country of residence.
9. Personal data
How data is processed is described in the Privacy policy.
10. Changes to these terms
The Service Provider will announce changes in the game at least 14 days before they take effect. Continuing to use the game after that date means accepting the new version. If you do not agree with it — you can delete the account.
11. Governing law
Matters not covered here are governed by Polish law. These terms do not limit consumer rights arising from mandatory provisions of law, including those of your country of habitual residence.
