Opero respects your privacy. This Privacy Policy explains how information is handled when you use the Opero mobile application.
Opero does not require users to create an account and does not collect personal information such as email addresses, phone numbers, or real names.
The app may store the following information locally on the device:
All of this information is stored locally on the user’s device and is never transmitted to external servers controlled by the developer.
Opero may request access to the device microphone and speech recognition features to allow users to answer math questions using their voice.
Voice input is processed using Apple-provided APIs. Opero does not record, store, or transmit audio or voice data.
Opero may send local notifications to remind users to practice math. These notifications are generated and managed entirely on the device and do not involve any external servers.
Opero offers an optional auto-renewable subscription ("Opero Premium") that unlocks additional features within the app.
All purchases are processed securely through Apple’s App Store using Apple’s in-app purchase system. Opero does not collect or store credit card information, payment details, or billing information.
To manage subscriptions and verify purchase status, Opero uses RevenueCat, a subscription management service. RevenueCat processes purchase receipts and limited technical information (such as anonymized device identifiers and transaction status) solely for the purpose of validating subscriptions and enabling premium access.
No personal information such as names, email addresses, or financial information is collected or stored by the developer.
Opero does not use third-party advertising services or analytics tools.
The app integrates Apple’s in-app purchase system and RevenueCat exclusively for subscription management and purchase validation. These services process only the information necessary to complete transactions and verify subscription status.
Opero does not use tracking technologies, behavioral profiling, or personalized advertising.
Opero does not sell, share, transmit, or disclose user data to any third parties. Data is processed only where strictly necessary for subscription validation through Apple and RevenueCat.
Opero is designed to be safe for children and users of all ages. The app does not knowingly collect personal information from children under the age of 13.
Because Opero does not collect personal data, does not include third-party advertising, and does not use analytics services, it complies with the Children’s Online Privacy Protection Act (COPPA).
Subscription purchases are protected by a parental gate mechanism to prevent unintended purchases by children.
This Privacy Policy may be updated from time to time. Any changes will be published on this page and reflected within the app where appropriate.
