Privacy Policy
Last updated: April 20, 2026
1. Introduction
Welcome to Chessever. We are committed to protecting your privacy and ensuring you have a positive experience using our app. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application.
2. Information We Collect
We may collect the following types of information:
- Account Information: When you create an account, we collect your email address and username.
- Usage Data: We collect information about how you use the app, including features accessed, games viewed, and tournaments followed.
- Device Information: We may collect device type, operating system, and unique device identifiers for analytics and app improvement.
- Purchase Information: If you subscribe to premium features, payment processing is handled by Apple App Store or Google Play Store. We do not store your payment card details.
3. How We Use Your Information
We use the information we collect to:
- Provide, maintain, and improve our services
- Personalize your experience and deliver relevant content
- Process transactions and manage subscriptions
- Send you notifications about tournaments, games, and updates
- Analyze usage patterns to improve the app
- Respond to your comments, questions, and requests
4. Data Sharing and Disclosure
We do not sell your personal information. We may share your information in the following circumstances:
- Service Providers: We may share data with third-party service providers who assist us in operating the app (e.g., analytics, cloud hosting, attribution, crash reporting). See Section 9 for a full list.
- Affiliate & Creator Partners: If you install the app through an affiliate or creator link, we share aggregated and user-level install, event, and conversion data with that partner through AppsFlyer so they can measure the performance of their referrals and receive their commission. We do not share your email address, name, or direct identifiers with affiliate partners without your explicit consent.
- Legal Requirements: We may disclose information if required by law or in response to valid requests by public authorities.
- Business Transfers: In the event of a merger, acquisition, or sale of assets, your information may be transferred.
4a. Advertising Identifiers & Attribution
We use attribution technology to understand how people discover Chessever — whether through search, word of mouth, a creator or affiliate link, or a paid campaign. This allows us to compensate the partners who bring users to the app and invest in channels that actually grow a healthy community.
Identifiers We May Process
- IDFA (iOS): Apple's Identifier for Advertisers. Only collected if you explicitly grant permission through the App Tracking Transparency (ATT) prompt on iOS 14.5 and later. If you decline, we do not collect IDFA and instead rely on Apple's privacy-preserving SKAdNetwork framework.
- GAID (Android): Google's Advertising ID. You can reset it or opt out of personalized advertising through your device's Google Settings at any time.
- AppsFlyer ID: A random, per-install identifier created by AppsFlyer. It is not tied to your real-world identity and cannot be used to contact you.
- Install Referrer: On Android, the Google Play Install Referrer is used to match an install to the click that drove it.
- Campaign & Creative Parameters: UTM-style parameters, affiliate codes, and creator sub-IDs embedded in the OneLink you click.
Your Choice (iOS)
On iOS, we will ask you for permission to use IDFA the first time you open the app. You can change your decision at any time in Settings → Privacy & Security → Tracking, and within Settings → Chessever → Allow Tracking. If you decline or later revoke permission, attribution continues to work through Apple's SKAdNetwork, which is aggregated and cannot identify you.
Your Choice (Android)
On Android you can reset or delete your advertising ID at any time under Settings → Privacy → Ads. Enabling "Delete advertising ID" causes Google to return a string of zeros, which AppsFlyer and Chessever treat as no-tracking.
5. Data Security
We implement appropriate technical and organizational measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the Internet or electronic storage is 100% secure.
6. Data Retention
We retain your personal information for as long as your account is active or as needed to provide you services. You may request deletion of your account and associated data at any time by contacting us.
7. Your Rights
Depending on your location, you may have the following rights:
- Access your personal data
- Correct inaccurate data
- Request deletion of your data
- Object to processing of your data
- Data portability
8. Children's Privacy
Our app is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe we have collected information from a child under 13, please contact us immediately.
9. Third-Party Services
To operate Chessever we rely on a small number of well-known processors. Each one receives only the minimum data it needs, and each is contractually bound to use it solely on our behalf. We do not sell any of this data.
