MainQuest Privacy Policy

Effective Date: June 2025 · Last Updated: November 5, 2026

MainQuest ("MainQuest," "we," "our," or "us") respects the privacy of people who use our mobile games, websites, player support, and related services (the "Services"). This Privacy Policy explains what information may be processed when you use the Services, why we process it, and the choices available to you.

We do not directly collect or require players to enter their legal name, date of birth, phone number, or email address during ordinary gameplay, and we do not independently verify a player's age or identity using those details. Information voluntarily submitted to support and technical or game-related data processed to operate games, analytics, security, and advertising are addressed separately below.

1. Scope of This Policy

This Policy applies to MainQuest games, websites, apps, player support, events, and related features that link to it. Features and third-party services can differ by game. If a particular game collects additional information, we will provide an appropriate notice in the relevant feature or separately.

For conditions governing use of the Services, please see our Terms of Service.

2. Information We Process

A. Information you choose to provide

We do not require your legal name, date of birth, phone number, email address, or a separate password for ordinary gameplay. If you contact support or join an optional event or survey, we may process information you choose to provide, such as your email address, message, game ID, purchase order number, or screenshots.

B. Gameplay and technical data

Depending on the game and its configuration, the following information may be generated or processed where necessary:

  • Game-assigned player identifiers, progress, saved data, inventory, achievements, gameplay activity, matches, and in-game interactions
  • Connection IP addresses, device and operating system details, app versions, connection and error logs, crash reports, and performance diagnostics
  • Where advertising or analytics tools are used, advertising identifiers (if available and permitted), ad impressions and interactions, installation attribution, and analytics events

Identifiers and technical data can qualify as personal information even when not linked to a person's real name. The precise categories depend on the game, SDKs, and your device settings.

C. App stores and connected platforms

Apple App Store and Google Play process in-app payments. For those transactions, MainQuest does not directly collect full payment card numbers, card security codes, or payment passwords. We may receive or verify purchase status, product identifiers, and transaction or receipt identifiers to grant purchased content and address related issues. If a game supports platform login, it may process a platform-issued account identifier.

D. Website storage technologies

This Privacy Policy page may save your language selection in your browser's local storage. Other website pages may use essential cookies or similar technologies as needed for features actually provided; some can be managed in browser settings.

3. How We Use Information

We use the information we actually process only where needed for purposes such as:

  • Running games, saving progress, managing game accounts, items and purchase entitlements, and responding to support requests
  • Maintaining network reliability, diagnosing errors, improving games, and protecting service security
  • Preventing cheating, fraud, and purchase abuse, and resolving disputes
  • Operating analytics and advertising measurement where used by a game, subject to applicable consent and platform settings
  • Fulfilling legal obligations

We do not collect email addresses or phone numbers for unrelated promotional contact without an appropriate legal basis or consent. We may use aggregate information that does not identify individuals to understand and improve games.

4. Sharing and Service Providers

We do not sell personal information. Depending on the services actually used by a game, information may be processed by these types of providers when necessary:

  • App stores and platform providers for platform sign-in, purchase authorization and validation, and payment-related support
  • Cloud and server providers for game hosting, data storage, and security
  • Analytics, advertising, and attribution providers for games that include their SDKs
  • Customer-support providers where applicable

Where providers process information under our instructions, we apply protections required by applicable law. We may also disclose limited information in response to lawful requests, to protect legal rights, or with your separate consent.

The specific service providers, data categories, retention periods, and any legally required overseas-transfer disclosures depend on the services actually used. Where required, we will provide these details in the Services or update this Policy.

5. Children and Age Information

We do not request a date of birth or actual age during ordinary gameplay and do not independently check a player's age. The relevant game's store age rating and applicable laws continue to apply.

Where parental consent or safeguards for children are required by law or platform policy, we will comply. If we learn that children's personal information has been processed improperly, we will take appropriate steps to delete or restrict it. Parents and guardians may contact help@mainquest.biz.

6. Your Rights and Choices

Depending on applicable law, you may have rights to access, correct, delete, or restrict processing of your personal information, or withdraw consent. Contact help@mainquest.biz to make a request. If an in-game account deletion feature is available, you may use it.

We may request limited verification information, such as a game ID, to locate the relevant records and prevent unauthorized deletion. Because some games do not collect names or emails, recovery or processing of a particular request may be technically limited if we cannot reliably identify the relevant record.

You can manage relevant ad-tracking permissions and device identifiers through operating-system, store, or in-app settings. Certain records may need to be retained despite a deletion request where law requires it.

7. Retention and Deletion

We keep personal information only for as long as reasonably necessary to provide the relevant game, answer support inquiries, maintain security, resolve disputes, or meet applicable legal requirements. When the purpose ends or a retention period expires, we delete or de-identify the information without undue delay as required by law.

Gameplay records may be needed while a game service or account feature operates. Support correspondence may be retained for resolution and necessary follow-up. Transaction or dispute records may be retained separately for statutory periods when required.

Actual periods depend on the record type, the game and SDK configuration, and legal requirements. Payment information held independently by app stores is governed by their own privacy practices.

8. Security

We take reasonable administrative, technical, and operational steps to safeguard personal information and game data, including appropriate access controls. No internet-based system can be guaranteed perfectly secure. If a reportable incident occurs, we will take appropriate action and notify affected people where required by law.

9. Changes to This Policy

We may revise this Policy as our Services, technology, or legal requirements change. We will update the "Last Updated" date and provide further notice where required by law or appropriate for material changes affecting your rights.
