To protect our rights and interests: To detect, prevent, and address fraud, security issues, and other illegal activities, and to enforce our terms of service.

3. Data Storage and Local-First Approach

FlashWord employs a local-first approach to data storage, which means that by default, all your flashcard data, learning history, and personal content are stored locally on your device. This data is not automatically sent to our servers unless you explicitly choose to enable cloud synchronization features.

We believe this approach gives you greater control over your personal information and enhances your privacy by minimizing the amount of data that is transmitted and stored on external servers.

4. Sharing Your Information

We do not share your personal information with third parties except in the following circumstances:

With service providers: We may share your information with third-party service providers who help us operate the App, such as hosting providers, payment processors, and analytics services. These service providers are contractually obligated to protect your information and use it only for the purposes for which we disclose it to them.
For legal reasons: We may disclose your information if required to do so by law, or in response to valid requests by public authorities (such as a court or government agency).
To protect our rights: We may disclose your information to protect our rights, property, or safety, or the rights, property, or safety of others.
In connection with a business transfer: If we are involved in a merger, acquisition, or sale of all or a portion of our assets, your information may be transferred as part of that transaction.

Location information: You can control whether the App has access to your location through your device's settings.

We take reasonable measures to protect your personal information from unauthorized access, use, or disclosure. These measures include:

Encryption of data stored on your device and data transmitted between your device and our servers.
Secure authentication mechanisms for account access.
Regular security updates and maintenance.

However, no method of transmission over the internet or electronic storage is completely secure, so we cannot guarantee absolute security.
