Privacy policy

Who is responsible

The operator of Proton and this website is individual entrepreneur Ostap Mykolaiovych Andreikiv (ФОП Андрейків Остап Миколайович), Ukraine. For privacy questions and rights requests, contact proton@kryga.com.ua. This policy covers the game, its cloud features, support, and proton.kryga.com.ua.

Information we process

Without signing in, progress, preferences, your deck, and equipment are stored on your device. An account uses a user identifier, chosen nickname, and Apple or Google sign-in provider. The provider may supply a name, email address, and verification status. Your Apple or Google password stays with that provider; the game and Proton team do not receive it.

A cloud save contains game progress, including completed waves and stages, resources, heroes, runes, upgrades, your deck, and preferences, along with technical versions and save timestamps. One-time rewards have claim records. When you contact support, we receive your email address, message, and any attachments you choose to send.

To provide connections and prevent abuse, our server and service providers may process IP addresses, device and system information, technical events, and session information. The game does not request access to contacts, the microphone, the camera, or precise location.

Why we use information

We use information to provide and protect accounts, reserve unique nicknames, save and restore progress, verify reward claims, and answer support requests. Depending on the situation, the legal basis is performing our terms of use, a legitimate interest in protecting the service, consent, or a legal obligation. Consent may be withdrawn without affecting the lawfulness of earlier processing.

Providers and advertising

We use Google Firebase Authentication for sign-in and Cloud Firestore for cloud progress. If you use Apple or Google sign-in, that provider supplies authentication information and available account details. See the privacy information for Firebase, Apple, and Google.

When voluntary rewarded advertising is available and you request an ad, Google AdMob may process technical identifiers, an IP address, an approximate region, ad impressions, and ad interactions. Regional consent options and iOS restrictions apply. Where the relevant option is available, you can change ad privacy choices in the game. Read about Google’s advertising technologies.

The game does not integrate Firebase Analytics or Crashlytics. This website uses no analytics pixels, advertising cookies, or embedded third-party videos; fonts and images are served from our server. Providers are used for their relevant functions and service protection, under the data-protection obligations in their applicable terms.

Storage and international processing

Account information and cloud progress are kept while you use the account or until you delete it. Support correspondence is kept as needed to resolve the request, address related follow-up issues, and protect legal rights. Providers may have separate retention periods for technical information.

Firebase Authentication processes data in the United States; other Google services may process it in other countries. Transfers use safeguards under applicable provider terms and law, including contractual protections. Firebase states that authentication information is removed from live and backup systems within 180 days after deletion is initiated.

Deletion and local progress

In the game, open Profile → Account → … → Delete account and confirm. You may need to sign in again. The cloud profile, primary cloud save, nickname reservation, and one-time login reward record are deleted, followed by the authentication account. See account deletion instructions.

Deleting the cloud account does not reset local gameplay or local device backups. To remove those, use the progress reset option in settings and remove the app and its data from the device. iCloud backups are managed through Apple settings. Contact support if you cannot complete in-game deletion.

Your rights

Depending on where you live, you may have rights to access, correction, deletion, restriction, objection, portability, and withdrawal of consent. Contact proton@kryga.com.ua. We may verify account ownership, but will not ask for your password. You may also contact your local data-protection authority. Requests are handled within the time required by applicable law.

Younger players

Where local law requires a legal representative’s involvement in using an account or providing consent, use those features together with that representative. A parent or guardian may contact us about a child’s information or its deletion. We do not ask for a date of birth or for a child’s identity documents in routine support requests.

Changes

If game features or data practices change, we will update this page and its revision date. Where a change requires separate consent, we will provide the relevant notice before that processing.
