Capybara Survivor (カピバラサバイバー)

Privacy Policy

Effective date: October 27, 2026 (first published: September 17, 2026)

日本語

megu games (the “Operator”) explains below how the game app “Capybara Survivor” (カピバラサバイバー, the “App”) handles information. This policy applies to the iOS edition distributed on the App Store, the Android edition distributed on Google Play (together, the “mobile editions”), the PC edition sold on Steam, the browser version that you can play in a web browser, and this website. The Japanese version is the original; if the two versions differ, the Japanese version prevails.

The App has no account in which you register your name or email address. Only if you use online play in the iPhone edition, an anonymous ID for your device is created automatically through Epic Online Services, provided by Epic Games, Inc. (see 6-2. Online play (iPhone edition)). The App does not ask you to enter your name, email address or phone number. You can also open this policy from the link on the App’s title screen.

1. Operator and contact

Operator: megu games

Contact (including privacy inquiries): megu0xxx0x@gmail.com

This website has no contact form. Please send inquiries by email. Matters that Japan’s Act on the Protection of Personal Information requires us to make known to you (such as the operator’s name and address) will be provided without delay on request.

2. Summary of information handled

The table below lists the information handled by the App and this website, why it is used, where it goes and how long it is kept.

(Epic Online Services). When other players open the Ranking (leaderboard) screen, your points, match count, name tag number, “Hide me from the ranking” flag and user ID are delivered to their App, and your points and name are shown. Rows of players who chose “Hide me from the ranking”, and rows after “Delete Online Data” (when a connection is available), are delivered but not shownStored in the area for this game that the Operator has set up in Epic Online Services. After “Delete Online Data”, the user ID with its points and match count remains (if a connection is available, the current month’s record has its name set to nameless and the hide flag set; records for earlier months also keep that month’s name tag number and are not given the hide flag by this operation, but the App’s Ranking screen shows only the current month’s leaderboard). Once the device credential is deleted, the Operator has no means to link this ID to you. Information on Epic’s servers is also handled under Epic’s own rules (see 10. Retention and deletion requests)
On-device ranking copy (iPhone edition version 2.3 and later: the number of matches counted that day, this month’s points and match count, lineup keys used to avoid counting matches with the same players too often (short strings shortened from the set of IDs of the players in the room), and your “Hide me from the ranking” setting)Checking the daily limit of counted matches, showing “this month’s points” on the results screen, and keeping your display settingNot sent (stored on your device)Until you delete the App, or until it is deleted with “Delete Online Data”

(the App Store’s public lookup service, itunes.apple.com). The App sends only this App’s identifier and the store country parameter (the country chosen from your device’s language/region setting; Japan if it is unknown or that country’s store does not answer), and no game records; the connection itself lets Apple receive your IP address and approximate locationThe result (the published version, when it was checked, and the version whose notice you closed) is stored on your device until you delete the App. Connection information that reaches Apple is handled as set by Apple

Connection information when you visit this website (such as IP address)Delivering, maintaining and securing the websiteGitHub (GitHub Pages)As set by GitHub

The game features of the App do not use your contacts, photo library, microphone, camera or GPS location. The App has no function that automatically sends game records or play statistics to the Operator’s servers. If you use online play in the iPhone edition, only the information needed for the match and the leaderboard is sent to Epic Online Services and to the other players’ devices. From version 2.3, your leaderboard points, match count and name tag number are stored on Epic Online Services and delivered to and shown in other players’ App (see 6-2. Online play (iPhone edition)). From iOS version 2.1, the App queries Apple’s App Store to check whether a newer version is available (“Update check” in the table). Name tags in online play are made from words prepared by the App and cannot be typed freely. There is no chat feature. The Operator does not sell the information it handles.

3. Information stored on your device or PC

The App stores game progress, unlocked companions and hats, the selected character, settings and data for resuming a run on your device (on your PC for the PC edition). It also stores recent operation records for troubleshooting and the “Remove Ads” purchase status confirmed with the store. If you use online play in the iPhone edition, the App also stores your name tag choice and the device credential of Epic Online Services on your device. From version 2.3, for the leaderboard, it also stores the number of matches counted that day, this month’s points and match count, lineup keys used to avoid counting matches with the same players too often (short strings shortened from the set of IDs of the players in the room), and your “Hide me from the ranking” setting. From iOS version 2.1, it also stores the result of the update check (the published version, when it was checked, and the version whose notice you closed).

This on-device information is not sent to the Operator, and the Operator cannot view or delete it. Records may be lost if you delete the App or change devices. If you use an OS backup feature such as iCloud or Google backup, these records may be included in the backup, which is handled under that service’s own rules.

4. Advertising (mobile editions)

The mobile editions use Google AdMob. When an ad is ready, it may be shown after a run ends (for example, after game over). Preparation of the ad service may start when the App launches. Advertising information is collected automatically by Google’s ad SDK built into the App when the SDK starts and when ads are prepared or shown, and is sent to Google. The PC edition and the browser version have no ads.

The iOS edition version 2.0 and later uses AdMob mediation (a system that chooses ads from several ad companies) and also includes the ad SDKs of AppLovin Corporation (AppLovin), Unity Technologies (Unity Ads), Liftoff Mobile, Inc. (Liftoff Monetize) and Meta Platforms, Inc. (Meta Audience Network). When ads are prepared or shown, these SDKs also automatically collect advertising information and send it to their companies.

Ads are limited to content suitable for general audiences. By default, ads are requested as non-personalized ads, which are not based on your past behavior. Only in the iOS edition version 2.0 and later, and only if you allow tracking (see “iOS” below), are personalized ads requested. The Android edition always requests non-personalized ads. Even with non-personalized ads, information is used for serving ads, frequency capping, measurement, fraud prevention and maintaining and improving the service. According to Google, when non-personalized ad requests are sent to bidders, user identifiers such as advertising IDs are removed and only part of the IP address is sent.

iOS: In version 2.0.1 and later, when you open the App and the title screen appears, the App shows a short explanation and then the iOS tracking permission prompt (App Tracking Transparency). It is shown only while you have not yet answered it (iOS shows the prompt itself only once). It is also shown to people who have removed ads with “Remove Ads”, but whichever they choose, the App does not show them ads. Only if you allow tracking does the App request personalized ads using the advertising identifier (IDFA); in regions where Google’s consent screen is shown, your choices on that screen also apply (see below). If you do not allow it, the IDFA is not used, and the game plays the same. You can change your choice at any time (see 9. Withdrawing consent and changing settings). Version 1.1 and earlier do not ask for tracking permission and do not use the IDFA. The ad SDK may handle device identifiers scoped to the app or developer. The App has turned off Google’s publisher first-party ID.

Android: The ad SDK handles the Android advertising ID and the app set ID and, where applicable, identifiers related to accounts signed in on the device. You can reset or delete the advertising ID in your device settings (see 9. Withdrawing consent and changing settings).

The countries and regions where the mobile editions are available are shown in each store, and may include countries and regions outside Japan. In the iOS edition version 2.0 and later and in the Android edition, the App uses Google’s User Messaging Platform (UMP) SDK at launch to check whether an ad consent message is required in your region. No consent screen is shown in Japan. In regions where consent is required, such as the European Economic Area (EEA), the UK and Switzerland, Google’s consent screen is shown (on the title screen in the iOS edition, and at launch in the Android edition), and ads are requested after you make your choices there. You can review and change your choices at any time from “Ad Settings” (広告の設定) on the title screen (see 11-2. For users in the EEA, the UK and Switzerland). iOS versions 1.1 and earlier include the UMP SDK but do not call it.

Once a “Remove Ads” purchase is confirmed, the App shows no ads. On launches after the purchase is confirmed, the App does not initialize the ad SDK or request ads. This does not undo processing that took place before the purchase or connections that had already started before the purchase was confirmed. The App keeps communicating with the store to check purchase status.

For how Google uses, stores and manages information, see:

For the other ad SDKs used in the iOS edition version 2.0 and later, please see each company’s explanation.

5. In-app purchase and restore (mobile editions)

“Remove Ads” (広告を消す) on the title screen or the results screen offers two ways to stop ads from being shown: “Ad-Free (One-Time Purchase)” (広告なし（買い切り）), a one-time purchase that does not renew, and, in the iOS edition version 2.1 and later, “Ad-Free (Monthly)” (広告なし（月額）), an auto-renewable subscription with a one-month period. In this policy, “Remove Ads” refers to either of them. The monthly subscription renews automatically unless you cancel it at least 24 hours before the end of the current period. After you cancel, ads stay off until the end of the period and are shown again after it ends. The iOS edition uses Apple’s App Store for purchases, the subscription and restores, and the Android edition uses Google Play’s billing system for purchases and restores.

The App checks the product identifier and purchase status on your device and applies the ad-free entitlement. It also asks the store for your purchase status when it launches, and shows no ads if you have purchased. For the monthly subscription, the App keeps the expiry date of the current period on your device and asks the App Store again when the period ends. The App is designed so that the Operator does not receive card numbers or payment passwords.

After changing devices or reinstalling, you can restore your purchase with “Restore Purchases” (購入を復元) on the title screen, using the same Apple Account or Google Account used for the purchase. Restoring a purchase does not move unlocked characters or play records to another device.

For purchases on Google Play, Google may provide order information to the Operator as described by Google. The Operator uses it only as needed to confirm purchases, handle refunds and inquiries, and for accounting and tax purposes.

For how payment information is handled, see:

6. PC (Steam) edition

The PC edition is a paid, one-time purchase sold on Steam. It has no ads, no in-app purchases and no analytics, and the App has no function that sends information to the Operator or any other third party. Game records are stored on your PC (Windows: %APPDATA%\jp.hosoda.capybarasurvivor; macOS: ~/Library/Application Support/jp.hosoda.capybarasurvivor). If you select “プライバシーポリシー” (Privacy Policy) or “サポート・お問い合わせ” (Support) on the title screen, this website opens in your default browser, not in the game window (see 12. This website).

Purchases, library management and downloads on Steam are handled by Steam, provided by Valve Corporation, under Valve’s Privacy Policy. The App does not currently save records to Steam Cloud.

6-2. Online play (iPhone edition)

In the iPhone edition, “Online Battle (Beta)” (オンライン対戦（β版）) on the title screen lets you play with up to 10 people (up to 6 in version 2.2 and later). “Duel!” (決闘！) finds other players and starts; seats that are not filled are taken by AI Keepers (computer players). “With Friends” (友だちと) lets you join a room with a 6-digit passcode.

Online play uses Epic Online Services (“EOS”), provided by Epic Games, Inc. When you first look for an opponent (from version 2.3, also when you first open the Ranking (leaderboard) screen), the EOS device feature (Device ID) creates an anonymous credential for this device and a user ID for this game. No Epic account is needed. The App does not send your name or email address to EOS.

During a match, your name tag, chosen character, controls and match state are exchanged with the devices of other players in the same room. In online play, to make communication faster, your device tries to connect directly to the devices of other players in the same room, and in doing so your IP address may be passed to their devices. When a direct connection cannot be made, communication goes through Epic’s relay. The Operator does not collect these IP addresses.

If someone who does not know the passcode joins a room, the person who created the room can remove them.

From version 2.3, for the leaderboard, your monthly versus points, the number of counted matches and your name tag (the number of a combination of preset words) are stored on EOS servers together with the user ID for this game. When other players open the Ranking (leaderboard) screen, your points, match count, name tag number, “Hide me from the ranking” flag and the user ID for this game are delivered to their App, and your points and name are shown. Points are given in matches with other players (AI Keepers do not count). The leaderboard changes every month. If you choose “Hide me from the ranking” (ランキングに出さない), the App does not show your row on its Ranking (leaderboard) screen (the record stays on EOS servers and is still delivered to other players’ App, but is not shown). The Operator does not store match results or records on its own servers. For how EOS handles information, please see the privacy policy of Epic Games, Inc.

The battle feature is in the iPhone edition of the App, and can also be played on iPad in version 2.2 and later. In this policy, “iPhone edition” in connection with online play includes iPad in version 2.2 and later. The entry to battles is not shown when the iOS app runs on a Mac, or in the Android, PC (Steam) or web editions.

6-3. Browser version (web)

The browser version is a free edition that you can play in a web browser without installing anything (https://tilcayo.games/; the same edition is also served at https://capybara-survivor.megu0xxx0x.workers.dev/). It has no ads, no in-app purchases, no analytics and no online play, and it does not include any feature that sends your game records or actions to the Operator or to any other third party.

Game records and settings (best records, unlock progress, the character you chose, sound and smoothness settings, and so on) are stored in your browser’s storage (localStorage and similar). The number of times the page has been reloaded after losing connection is kept temporarily in storage that is cleared when you close the tab (sessionStorage). Copies of the files needed to play (images, sounds and program files) are also stored in your browser’s storage (the Service Worker cache) so that you can keep playing when you are offline. Neither is sent anywhere. If you delete your browsing history or site data, your records are deleted as well. Safari (iPhone, iPad and Mac) may delete data for sites that have not been used for a while, which also deletes your records. Opening the game from your Home Screen makes this automatic deletion less likely.

The pages and files are delivered through the network of Cloudflare, Inc. As part of delivering them, your IP address, browser type, the files requested and the date and time reach Cloudflare. The Operator does not use this information for analytics or advertising. See Cloudflare’s Privacy Policy.

If you press a notice such as “App version (App Store)”, the App Store page opens in a new tab. Information on that page is handled under Apple Inc.’s privacy policy. Whether you closed a notice is stored only in your browser.

7. Third parties and protection

The third parties with which the App shares user information, and their roles, are:

Information about purchases and downloads of the PC edition is handled by Valve Corporation through Steam, not by the App.

The Operator uses Google LLC, Apple Inc., GitHub, Inc. and Cloudflare, Inc. after confirming that, under their own privacy policies and the terms and data protection terms the Operator has accepted, they provide the same or equal protection of user information as described in this policy. For AdMob, the Google Ads Controller-Controller Data Protection Terms, incorporated in the AdMob terms, apply where applicable (list of covered services).

Epic Online Services, provided by Epic Games, Inc., is used under the Epic Online Services Developer Agreement that the Operator has accepted. For how EOS handles information, please see the privacy policy of Epic Games, Inc.

AppLovin, Unity Ads, Liftoff Monetize and Meta Audience Network are used through Google AdMob mediation and under each company’s terms and privacy policy. For how they handle information, please see their privacy policies (see section 4).

The Operator does not provide user information to any other third party, except as required by law. Google may, under its own policies, send ad request information to advertisers and bidders in its ad network in order to serve ads. The ad companies listed above may do the same under their own policies (see section 4).

8. How we protect information

The only user information the Operator holds that may include names or contact details is what is contained in support emails. It is kept in the Operator’s email account and deleted when no longer needed.

The anonymous IDs, room information, and leaderboard points, match counts and name tag numbers for online play in the iPhone edition are managed in the area for this game that the Operator has set up in Epic Online Services, and are not stored on the Operator’s own servers. They are linked to a user ID and do not include names or contact details. The Operator may view and manage them in Epic’s developer console as needed to run the leaderboard, for example to investigate misuse.

Game records are stored on your device or PC and are not sent to or stored on the Operator’s servers. According to Google, all data collected by Google’s ad SDK is encrypted in transit using TLS. Payments are processed by each store’s own systems.

9. Withdrawing consent and changing settings

You can change or stop the handling of ad-related information as follows. Menu names and locations vary by device and OS version.

The iOS tracking permission and the choices on Google’s consent screen are separate settings. The App requests personalized ads only if you have allowed tracking and, in regions where the consent screen is shown, after you have made your choices on it. Your choices on the consent screen are saved on your device so that the ad SDKs in the App can refer to them.

10. Retention and deletion requests

Support information is kept only as long as needed for support and related checks, and information no longer needed is deleted. If the law requires retention, it is kept to that extent. Please do not include unnecessary personal information in emails.

To request access to, correction of, suspension of use of, or deletion of support information held by the Operator, email megu0xxx0x@gmail.com from the address you used for your inquiry, with a subject such as “Deletion request”. After confirming that the request comes from you, the Operator will respond without undue delay in accordance with applicable law and tell you the result.

11. Age and children

The App repeatedly features fantasy combat between animals. The App is intended for people aged 13 and over, and its App Store age rating is 13+. It is not designed for children under 13, and the Operator does not knowingly collect personal information from children under 13.

If we learn that we have received personal information from a child under 13, for example in a support email, we will delete it promptly. Parents or guardians can contact us at the address above. Limiting ad content to general audiences is separate from the game’s own age rating.

11-2. For users in the EEA, the UK and Switzerland

This section adds information for people in the European Economic Area (EEA), the United Kingdom and Switzerland. The rest of this policy also applies.

Who is responsible: the Operator, megu games, is based in Japan and is responsible for the information it handles under this policy (the only information that may include names or contact details is what is contained in support emails; leaderboard records in the iPhone edition are pseudonymous information without names or contact details, managed in the area for this game that the Operator has set up in Epic Online Services; see 8. How we protect information). Contact: megu0xxx0x@gmail.com. The ad companies listed in section 7 handle the advertising information collected by their SDKs under their own privacy policies (for Google, under the Google Ads Controller-Controller Data Protection Terms; see section 7).

Legal bases: the legal bases for processing under the GDPR and the UK GDPR are as follows.

Game records and settings stored on your device or PC are not sent to the Operator (see section 3). How long information is kept is described in section 2 and section 10.

Your rights: depending on the law that applies to you, you can ask the Operator for access to your information, correction or deletion of it, restriction of or objection to its use, and a copy of information you provided in a portable format. Where processing is based on your consent, you can withdraw consent at any time, from “Ad Settings” (広告の設定) on the title screen or with the iOS tracking setting (see 9. Withdrawing consent and changing settings). Withdrawing consent does not affect processing that took place before. To make a request, email the address above (see 10. Retention and deletion requests). For advertising information, the Operator has no means to look up or delete information for an individual user; please use the ad companies’ own controls or contact them. For leaderboard records, the Operator cannot tell which record is yours, so please use “Delete Online Data” in the App (see 10. Retention and deletion requests).

Complaints: you can lodge a complaint with a data protection supervisory authority, in particular in the country where you live or work or where you think the problem took place. In the EEA, see the list of authorities on the European Data Protection Board website; in the UK, the Information Commissioner’s Office (ICO); in Switzerland, the Federal Data Protection and Information Commissioner (FDPIC).

International transfers: support emails are received by the Operator in Japan. The European Commission has decided that Japan ensures an adequate level of protection for personal data transferred from the EU to businesses in Japan (Decision (EU) 2019/419). The ad companies in the App are based in the United States: Google LLC and, in the iOS edition version 2.0 and later, AppLovin Corporation, Unity Technologies, Liftoff Mobile, Inc. and Meta Platforms, Inc. They may process information in the United States and other countries. The same applies to the other companies listed in section 7 (Google for Google Play and Gmail, Apple Inc., Epic Games, Inc., GitHub, Inc. and Cloudflare, Inc.). Each company describes the safeguards it uses for these transfers, such as the EU–U.S. Data Privacy Framework or the European Commission’s standard contractual clauses, in its own privacy policy (see section 4 and section 7). You can check which U.S. companies participate in the Data Privacy Framework on the Data Privacy Framework List.

12. This website

This website (https://megu0xxx0x.github.io/) is separate from the browser version of the game. For the browser version, see 6-3. Browser version. This website has no analytics of its own, ad SDKs, contact forms, external fonts or tracking scripts. It is hosted on GitHub Pages. GitHub may process connection information such as IP addresses for delivery, maintenance and security. See the GitHub General Privacy Statement.

13. Changes

We may update this policy when the way information is handled or the service changes. Updates are posted on this page with a new effective date. Important changes will be clearly announced on this page.
