These Terms of Service (“Terms”) govern the relationship between you and Ricardo Seiji Sato (“we” or “us”) regarding your use of the AMEBOOM™ game (Android app and web browser), the ameboom.com website (ameboom.com.br redirects to it), the test version at beta.ameboom.com, and related services (together, the “Service”). Your use of the Service is also governed by the Privacy Policy, which is incorporated into these Terms by reference.
By installing, accessing, playing, creating an account, or otherwise using the Service, you agree to these Terms. If you do not agree, do not install, access, or use the Service. Use of the Service is void where prohibited.
1. License
As long as you comply with these Terms, we grant you a limited, personal, revocable, non-exclusive, non-transferable, and non-sublicensable license to access and use the Service solely for non-commercial entertainment. You may not use the Service for any other purpose.
2. The Service
AMEBOOM™ is a casual multiplayer game in which the player controls an amoeba, collects resources, grows, and fights for the pond’s crown.
The Service may include:
- Free-for-All mode: matches that count toward the leaderboard, with up to 150 amoebas per pond, including real players and computer-controlled opponents;
- custom ponds, created by players with their own rules, which do not count toward the leaderboard;
- Playground mode: single-player matches on your device, for practice or fun, which do not count toward the leaderboard;
- amoeba evolution (EVO), match events (such as the Queen Hunt), accounts, progress, virtual items, ads, and purchases.
The version at beta.ameboom.com is a public beta. Features, rules, ponds, opponents, interface, and availability may be changed, suspended, or discontinued at any time.
The Android app is distributed through Google Play and is also subject to Google Play’s rules. In the app, real-money purchases are made through Google Play. In the web browser, the game is free to play, ads appear only on the page around the game (never inside the match), and purchases are made on the website through Mercado Pago or Stripe (section 6).
3. Eligibility
The game content is rated for all ages, but the Service is intended for people aged 13 and older.
If you are under 18, your use and purchases must take place with the knowledge and, where required by law, the permission of a parent or legal guardian. The parent or guardian is responsible for the use of the Service and for purchases made with their payment method; Google Play offers parental controls and purchase approval.
You may not use the Service if you have already been banned, or if you create an account with false information or on behalf of someone else.
4. Account
When you open the game, we automatically create a guest account, with no sign-up, that keeps your progress and purchases on that device. In the app, it is backed up to Google (see the Privacy Policy). Even so, without sign-up the account may be lost if you clear the app or browser data, or switch devices without Google backup turned on. To stop depending on the device, sign up (email and password) or sign in with Google: the same account then works on any device.
A purchase lost along with a guest account can be recovered with the RESTORE button, using the same Google account that paid, or through support, by providing the Google order number (GPA…).
You may sign in with Google. In that case, Google sends us your Google account identifier, name, and email, according to the permissions you accept on Google. Google’s processing of your data follows its own policy.
Your account is a means of accessing the Service. You do not acquire ownership of the account. All rights to the account remain with us.
You are responsible for keeping your login details safe and for all activity on your account, including purchases, whether or not you authorized them. Notify contato@ameboom.com immediately in case of loss, theft, or unauthorized use, and change your login details.
Do not share your account. You may not sell, rent, assign, or transfer accounts, items, or virtual currency outside the official features of the Service.
The username (@username) chosen at sign-up is unique and cannot be changed by the player. Usernames and amoeba names may not be offensive, mislead others, impersonate a brand, person, or the game’s team, or violate any law or store rule. We may refuse, change, or reclaim a name at any time, including in response to a complaint from a third party.
We may delete guest accounts with no sign-up and no purchases that have been inactive for more than 180 days.
5. Code of conduct
Among other things, you may not:
- cheat, exploit bugs, or use bots, scripts, unauthorized emulators, hacks, client modifications, or third-party software designed to alter the Service;
- alter game files without authorization or use any version of the app other than the original from Google Play;
- obtain an ad reward without watching the ad, or circumvent the verification of ads and purchases;
- manipulate the leaderboard, trade wins, or gain an unfair advantage over other players;
- disrupt, overload, or attack any server, account, data, or infrastructure, including through viruses or denial of service;
- gain unauthorized access by any means other than the official interface;
- harass, insult, threaten, or discriminate against players or support staff;
- post content that is offensive, obscene, excessively violent, or that infringes the rights of others;
- use any name or content involving the sexual exploitation of minors;
- reverse engineer, decompile, or extract code beyond what the law allows;
- ask other players for passwords, login details, or personal information;
- collect or publish personal data, documents, or financial information of others;
- use the Service for betting, gambling, or any equivalent activity on match results;
- use the Service for unauthorized advertising, spam, fraud, or illegal activity;
- abuse the support channel.
The Service does not offer chat between players. If in-game communication is added in the future, these rules apply to it. We may, but are not required to, monitor, record, edit, or remove content submitted to the Service.
We reserve the right to decide what violates the spirit of the Service and to warn, remove content, correct the leaderboard, or suspend or delete the account, with or without notice, without compensation for lost progress, names, items, or VIP Pass, except where required by law.
To protect matches, the app may check with Google whether it is the original version and whether it runs on a trustworthy device (Play Integrity API). Players who fail may be kept off the leaderboard and out of the shop, without losing the right to play.
You must cooperate with any investigation of fraud, cheating, or misuse.
6. Virtual items, gems, skins, and VIP Pass
With real money you may acquire only a limited, personal, non-transferable, non-sublicensable, and revocable license to use gems, skins, the VIP Pass, and other in-game items or features (“Virtual Items”). You may buy Virtual Items only through official channels of the Service: Google Play, inside the app, or the website store, through Mercado Pago or Stripe. Purchases on the website require a signed-up account (email or Google), not a guest account. You can also earn gems by playing, for example by watching rewarded ads or surviving the Queen Hunt, within the limits shown in the game.
Virtual Items are not legal tender, have no value outside the Service, and do not grant any property rights. We may manage, change, replace, or remove Virtual Items at any time.
The valid price is the one displayed in the game, on the website, or in the store at the time of purchase. Prices may change. This page does not list prices. You agree to pay any fees and taxes that apply to purchases made on your account.
The VIP Pass is a Google Play subscription that renews automatically at the end of each period (currently every 2 months), at the price and under the conditions in effect at renewal, until you cancel. While active, the VIP Pass removes all ads and grants the other benefits shown in the game. To cancel: Google Play app › Payments & subscriptions › Subscriptions. Canceling stops the next charge, and the VIP Pass remains valid until the end of the period already paid, with no prorated refund, except where required by law or by the store. Deleting your account in the game cancels the subscription before deleting the account.
Google Play purchases follow Google Play’s billing and refund policy, subject to the Brazilian Consumer Protection Code where applicable. A pending payment (for example, a bank slip) only unlocks the item once Google confirms it. If a purchase is refunded, canceled, or disputed (chargeback), we remove what it unlocked: gems (without leaving a negative balance), items, or the VIP Pass.
Where the law allows, purchases of digital content whose delivery begins immediately may not be withdrawn after delivery. Where the right of withdrawal cannot be waived, it prevails.
6.1. Website purchases and refund policy
Purchases made on the website are paid on the page of Mercado Pago (reais, Pix or card) or Stripe (U.S. dollars, card), which process the payment under their own terms. We do not receive card numbers. The item is delivered to your account as soon as the provider confirms the payment; a pending payment (for example, a Pix not yet confirmed) only unlocks the item after confirmation. On the website, the VIP Pass is a one-time purchase of 60 days, with no automatic renewal; buying it again adds another 60 days to what the account already has.
Refund within 7 days. You may ask for a full refund of a website purchase within 7 days of the payment, for any reason, as long as what it unlocked has not been used: the gems were not spent, the items were not unlocked or used, and, for the VIP Pass, you have not played any match with it active. This is the right of withdrawal of art. 49 of the Brazilian Consumer Protection Code, and we offer it to every player, wherever you live. After 7 days, or once the item has been used, there is no refund, except in these cases: the item was not delivered, the charge was duplicated or unauthorized, there was a failure on our side, or the law requires it.
How to ask. Write to contato@ameboom.com or use the contact form, with the @username (or the email) of the account and the order or payment number shown in the provider’s receipt. We reply within 5 business days. A refund goes back to the same payment method used, through Mercado Pago or Stripe, and the time it appears on your statement or Pix account depends on the provider and your bank. When we refund, we remove what the purchase unlocked (gems without leaving a negative balance, items, or the VIP Pass).
If you dispute a payment with your bank or card issuer (chargeback) without first contacting us, we also remove what the purchase unlocked and may suspend the purchases of the account while the dispute lasts. Please contact us first: it is faster. Purchases made through Google Play follow Google’s refund policy instead.
We do not exchange Virtual Items for money. Unused balances or benefits do not entitle you to compensation upon termination of the account, the beta, or the Service, except where required by law.
7. Ads
On the website, ads from Google AdSense appear only on the page where you play in the browser, around the game and never inside the match; the VIP Pass does not remove them. Their cookies, consent, and your choices are described in section 5.2 of the Privacy Policy.
In the app, players without an active VIP Pass see third-party ads provided by Google AdMob: rewarded ads, which you choose to watch in exchange for a benefit (respawn, continue a saved amoeba, earn a gem, try a skin); banners on the online match list and on the end-of-life screen; and full-screen ads when leaving a finished match, with a frequency cap. There are never ads while your amoeba is alive in a match. A rewarded ad’s benefit is only unlocked once Google confirms the ad was watched; if the confirmation does not arrive, you may try again while the game allows it. An active VIP Pass removes all ads. How data is handled in ads is described in the Privacy Policy. We do not control the content of third-party ads and are not responsible for products or services they advertise.
8. Leaderboard and Playground
The Free-for-All leaderboard may be corrected, recalculated, or reset in case of cheating, failure, abuse, or operational need. The Playground is not part of the leaderboard. There is no guarantee of rank, crown, reward, or season continuity.
9. Updates
The Service evolves. We may require you to accept updates to the game, the website, or third-party software in order to keep playing. Updates may occur with or without prior notice.
10. Availability
The Service is provided “as is” and “as available.” We do not guarantee access at the time or place of your choosing, uninterrupted operation, correction of every defect, compatibility with every device or browser, or freedom from viruses or harmful components.
We may perform maintenance, change rules, and discontinue modes, items, or the Service. When reasonable, we will announce relevant changes on the website or in the game. An interruption of the Service does not, by itself, entitle you to a refund or compensation, except where required by law.
11. Intellectual property
All rights to the Service — including the game, code, art, sound, animation, interface, names, methods of operation, documentation, client, and server — belong to Ricardo Seiji Sato or its licensors. These Terms do not transfer ownership to you.
Feedback, ideas, and bug reports may be used by us, without compensation, to operate and improve the Service.
12. Player content
“Player Content” is anything you submit to the Service, including names, profile images, and, if they exist in the future, messages. You represent that you have the right to submit this content, that it is not illegal, does not infringe the rights of others, and contains no malicious code.
You remain the owner of your Player Content and grant us a worldwide, royalty-free, non-exclusive, and sublicensable license to use, reproduce, adapt, and display that content in the Service and in the promotion of AMEBOOM™.
You are solely responsible for what you submit and for your interactions with other players. We have no obligation to mediate disputes between players. We may refuse or remove content at any time.
13. Privacy
Personal data is handled according to the Privacy Policy.
14. Stores and third parties
If you get the app from a store, the store is not a party to these Terms and is not responsible for the Service, unless its own rules say otherwise. Billing, renewal, cancellation, and refunds of purchases made in the store are handled by the store. For purchases on the website, billing is processed by Mercado Pago or Stripe, and refunds follow section 6.1.
The Service may contain links or third-party software, including Sign in with Google, Mercado Pago, Stripe, and Google AdSense. These features have their own terms. We are not responsible for third-party websites, ads, or services.
15. Disclaimer of warranties
To the fullest extent permitted by Brazilian law, the Service is provided without express or implied warranties of merchantability, fitness for a particular purpose, or non-infringement. Some warranties cannot be excluded; in those cases, the exclusion does not apply.
16. Limitation of liability and indemnification
To the fullest extent permitted by law, we are not liable for indirect damages, lost profits, loss of data, interruption of use, the conduct of other players, third-party ads, or the mere expectation of a reward.
Except in cases of willful misconduct, fraud, or any other case in which the law does not allow limitation, our total liability arising from the Service is limited to the amount you paid us in the six months before the event — or, if nothing was paid in that period, to ceasing use and closing the account.
Nothing in these Terms excludes consumer rights that cannot be excluded by contract, or liability for death or personal injury caused by our negligence.
You will indemnify Ricardo Seiji Sato for any loss, cost, and attorney’s fees arising from your illegal use of the Service, your violation of these Terms, or the Player Content you submit, except to the extent prohibited by consumer law.
17. Termination
You may stop using the Service at any time and delete your account instantly, in the game (Settings) or at ameboom.com/delete-account.html. If you have an active VIP Pass, the subscription is canceled first, with no refund for the period already paid (or you can ask through the contact form or the email below). Deleting your account does not by itself give a right to a refund of website purchases; the 7-day refund of section 6.1 applies, if you ask before deleting.
We may limit, suspend, modify, or terminate any account or access, with or without notice, in case of violation, suspected violation, legal risk, infringement of third-party rights, or discontinuation of the Service. Termination may include the loss of names, progress, and Virtual Items.
18. Changes to these Terms
We may change these Terms by publishing the new version at ameboom.com/terms.html. The date at the top shows the version in effect. Continued use after publication counts as acceptance, where the law allows. If you do not agree with the version in effect, you must stop using the Service.
19. General provisions
If any clause is held invalid, the others remain in effect. Failure to exercise a right is not a waiver. You may not assign these Terms; we may assign the Service and these Terms. These Terms, together with the Privacy Policy, are the entire agreement regarding the Service. Force majeure releases performance for as long as the impediment lasts.
20. Governing law and venue
These Terms are governed by the laws of the Federative Republic of Brazil. The courts of the consumer’s place of residence have jurisdiction, without prejudice to other venues the law grants the consumer.
