Privacy Policy

This Privacy Policy explains how Sero Games ("Sero Games", "we", "us", or "our") collects, uses, discloses, and protects information when you play, download, or otherwise use our mobile games and related applications, including but not limited to Combinai (collectively, the "Apps" or "Services"). It applies to all Apps published by Sero Games across the App Store, Google Play, and any other platform, regardless of the specific web address used to access this page.

By downloading, installing, or using any of our Apps, you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree with this policy, please do not use our Apps.

1.Information We Collect

We collect information in the following ways:

a. Information You Provide

• Account or profile information (such as a display name or avatar), if the App offers an account or social feature.
• Content you submit, such as customer support requests, survey responses, or in‑game messages/usernames.
• Information you provide when contacting us for support or feedback (e.g., your email address).

b. Information Collected Automatically

• Device information: device model, operating system and version, unique device identifiers, advertising identifiers (such as IDFA/GAID), language settings, and mobile network information.
• Usage & gameplay data: in‑game progress, levels completed, session length, in‑app actions, feature interactions, and crash/diagnostic logs.
• Approximate location: derived from your IP address or device settings, used for language/region, analytics, and ad relevance (we do not collect precise GPS location unless a specific game feature requires it and you grant permission).
• Log & performance data: IP address, app version, timestamps, and technical events used to diagnose crashes and improve stability.

c. Information From Third Parties

• Advertising and attribution partners may share information about ad interactions and install sources.
• App store platforms (Apple App Store, Google Play) may share purchase confirmation and device‑level data necessary to process transactions.
• If you connect a third‑party account (e.g., Google Play Games, Game Center) to enable features like cloud save or leaderboards, we may receive basic profile information from that service.

2.How We Use Information

We use the information we collect to:

• Operate, maintain, and provide the core features of our Apps;
• Save your progress and sync data across sessions or devices, where supported;
• Analyze usage trends to improve gameplay, performance, and stability;
• Personalize and measure the performance of advertising shown in our Apps;
• Process in‑app purchases and prevent fraudulent transactions;
• Respond to support requests, feedback, and bug reports;
• Detect, investigate, and prevent cheating, fraud, or other prohibited activity;
• Comply with legal obligations and enforce our terms.

3.Firebase & Analytics

Our Apps use Google Firebase, a mobile application development platform provided by Google, to support core app functionality. Depending on the App, this may include:

• Firebase Analytics — to understand how players use our Apps (e.g., screens viewed, features used, session frequency);
• Firebase Crashlytics — to collect crash reports and diagnostic data to help us fix bugs and improve stability;
• Firebase Cloud Messaging — to send push notifications about updates, events, or reminders (where permitted by your device settings);
• Firebase Remote Config & A/B Testing — to test and tailor in‑game content and features;
• Firebase Cloud Storage / Realtime Database / Firestore — to store game progress, settings, or leaderboard data where applicable.

Firebase may collect device identifiers, app usage data, and diagnostic information as described above. Google's use of this data is governed by the Google Firebase Privacy and Security policy and the Google Privacy Policy.

4.Advertising

Many of our Apps are free to play and supported by advertising. We work with third‑party advertising networks and mediation platforms — which may include providers such as Google AdMob, Meta Audience Network, Unity Ads, AppLovin, ironSource / Unity LevelPlay, Vungle / Liftoff, Chartboost, and similar ad‑serving companies — to display banner, interstitial, rewarded video, and native advertisements within our Apps.

These advertising partners may collect and use information such as your advertising identifier (IDFA on iOS, GAID on Android), IP address, device information, and app usage/interaction data to:

• Serve ads that may be relevant to your interests;
• Measure ad performance and prevent ad fraud;
• Limit how many times you see the same ad (frequency capping);
• Support rewarded ads that grant in‑game rewards in exchange for voluntarily viewing an ad.

On iOS, ad tracking is subject to Apple's App Tracking Transparency (ATT) framework — we (or our ad partners) will request your permission before tracking you across apps and websites for advertising purposes. On Android, you can reset or limit your advertising ID and opt out of interest‑based ads through your device's Google Settings. You may also generally opt out of interest‑based advertising through industry tools such as the Digital Advertising Alliance or Network Advertising Initiative.

5.In‑App Purchases

Some of our Apps offer optional in‑app purchases (such as removing ads, unlocking content, or purchasing virtual currency/items). All payments are processed directly by the Apple App Store or Google Play Store, and we do not directly collect or store your payment card details.

• Purchase transactions are governed by the terms and privacy policies of Apple and/or Google.
• We may receive limited, non‑financial purchase data (such as product ID, transaction status, and a receipt/token) to unlock content and validate purchases.
• We use this information to deliver purchased content, provide customer support, and detect fraudulent or duplicate transactions.

6.How We Share Information

We do not sell your personal information for money. We may share information as follows:

• Service providers: analytics, hosting, backend infrastructure (e.g., Google Firebase/Google Cloud), and customer support tools that process data on our behalf.
• Advertising & attribution partners: as described in the Advertising section above.
• App marketplaces: Apple and Google, to process purchases and distribute the Apps.
• Legal & safety reasons: to comply with applicable law, respond to lawful requests, or protect the rights, property, and safety of Sero Games, our users, or the public.
• Business transfers: in connection with a merger, acquisition, or sale of assets, where your information may be transferred as part of that transaction.

7.Third‑Party Services

Our Apps may include or link to third‑party SDKs and services that operate under their own privacy policies, including but not limited to:

Category	Example Providers	Purpose
Analytics & crash reporting	Google Firebase Analytics, Crashlytics	Usage insights, stability & bug fixing
Advertising & mediation	Google AdMob, Meta Audience Network, Unity Ads, AppLovin, ironSource	Displaying and measuring ads
Attribution	Firebase, AppsFlyer, Adjust (where used)	Measuring install sources and campaign performance
Cloud infrastructure	Google Cloud Platform / Firebase	Hosting, storage, and backend services
Payments	Apple App Store, Google Play Billing	Processing in‑app purchases

We encourage you to review the privacy policies of these third parties to understand how they collect and process information.

8.Data Retention

We retain information for as long as necessary to provide the Services, comply with legal obligations, resolve disputes, and enforce our agreements. Analytics and advertising identifiers are generally retained according to the retention policies of our third‑party providers (e.g., Google Firebase, ad networks), which may differ from the retention periods we apply to data we control directly.

9.Data Security

We use commercially reasonable administrative, technical, and organizational safeguards designed to protect information from unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

10.Children's Privacy

Our Apps are intended for a general audience and are not directed to children under the age of 13 (or the equivalent minimum age in your jurisdiction), unless a specific App is explicitly marketed as a children's app and designed to comply with applicable children's privacy laws (such as COPPA). If an App is directed to children, we limit data collection and advertising to what is permitted for child‑directed services and do not knowingly collect more personal information than necessary.

If we learn that we have collected personal information from a child under the applicable age of consent without verified parental consent where required, we will take steps to delete such information promptly. If you believe a child has provided us with personal information, please contact us using the details below.

11.Your Rights & Choices

Depending on your location, you may have the right to:

• Request access to the personal information we hold about you;
• Request correction or deletion of your personal information;
• Object to or restrict certain processing, including for advertising purposes;
• Request a copy of your data in a portable format;
• Withdraw consent, where processing is based on consent (e.g., ATT tracking permission, push notifications);
• Reset your advertising identifier or opt out of interest‑based ads via your device settings;
• Uninstall the App at any time, which stops further collection of device‑based data by that App.

To exercise these rights, contact us at [email protected]. We will respond within the timeframe required by applicable law.

12.International Data Transfers

Sero Games and its service providers (such as Google Firebase and advertising partners) may process and store information on servers located outside your country of residence, including in the United States and the European Union. Where required, we rely on appropriate safeguards (such as standard contractual clauses) to protect information transferred internationally.

13.Regional Disclosures

European Economic Area / UK (GDPR)

If you are located in the EEA or UK, our legal bases for processing your information include: performance of a contract (providing the App and its features), legitimate interests (such as analytics, security, and improving our Services), consent (such as ATT tracking or push notifications), and compliance with legal obligations. You have the right to lodge a complaint with your local data protection authority.

California (CCPA/CPRA)

If you are a California resident, you have the right to know what personal information we collect, request deletion of your personal information, and opt out of the "sale" or "sharing" of personal information (which may include certain advertising‑related data sharing). We do not sell personal information for monetary consideration. You may submit requests via [email protected].

14.Do Not Track

Some browsers support a "Do Not Track" (DNT) signal. Because there is no common industry standard for DNT, our Apps and this website do not currently respond to DNT signals. You can still manage advertising tracking through your device's privacy settings and Apple's App Tracking Transparency prompts.

15.Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or for other operational reasons. We will update the "Last updated" date at the top of this page when changes are made. Material changes may also be communicated through the App itself. Your continued use of the App after any update constitutes acceptance of the revised policy.
