Compubility LLC (“we,” “us,” or “our”) operates the Arithma mobile application (the “App”). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use the App.

We store your data using Neon, a serverless PostgreSQL database platform. Data is stored on secure, managed infrastructure with encryption at rest and in transit. We retain your data only for as long as necessary to fulfill the purposes described in this policy or as required by law.
We do not sell your personal information. We may share your information in the following circumstances:
Arithma displays advertisements served by Google AdMob. AdMob may use cookies, device identifiers, and similar technologies to serve ads based on your interests and prior interactions. You can opt out of personalized advertising by adjusting your device settings:
Opting out does not eliminate ads; it means ads shown to you may be less relevant.
Arithma offers in-app purchases and subscriptions managed through RevenueCat and processed by the Apple App Store or Google Play Store. We do not directly collect or store your payment card information. Payment processing is handled entirely by Apple or Google. RevenueCat receives transaction confirmations and subscription status to manage your access to premium features.
Arithma is a math puzzle game that may appeal to users of all ages. We do not knowingly collect personal information from children under the age of 13 without verifiable parental consent, in compliance with the Children's Online Privacy Protection Act (COPPA). If we learn that we have collected personal information from a child under 13 without parental consent, we will delete that information promptly.
If you believe your child has provided us with personal information, please contact us at the address below so we can take appropriate action.
We implement reasonable administrative, technical, and physical security measures to protect your information, including encryption in transit (TLS/SSL) and at rest. However, no method of transmission over the Internet or electronic storage is completely secure, and we cannot guarantee absolute security.

We do not sell personal information as defined by the CCPA.
Your information may be transferred to and processed in countries other than your country of residence. These countries may have data protection laws that differ from your jurisdiction. By using the App, you consent to the transfer of your information to the United States and other jurisdictions where our service providers operate.
We retain your personal information for as long as your account is active or as needed to provide the App's services. We will also retain information as necessary to comply with legal obligations, resolve disputes, and enforce our agreements. Gameplay data and statistics may be retained in anonymized or aggregated form indefinitely.
We may update this Privacy Policy from time to time. We will notify you of material changes by posting the updated policy within the App or by other means. The “Last updated” date at the top indicates when the policy was last revised. Your continued use of the App after changes constitutes acceptance of the updated policy.
