Privacy Policy

CaptionFlow ("we," "us," or "our") is a real-time AI-powered captioning and translation application. We take your privacy and personal data seriously. This Privacy Policy explains how we collect, use, store, share, and protect your personal information, and what rights you have over that data. Please read this policy carefully before using our services.

By using CaptionFlow, you agree to this Privacy Policy in full. If you have any questions, contact us using the details at the end of this document.

CaptionFlow provides real-time speech recognition and translation services. To deliver these services, we need to collect and use certain information about you. We understand how important your personal data is and are committed to protecting it in accordance with applicable laws and regulations.

We will only use your personal information for the purposes described in this policy and for no other purpose without your consent.

We collect information in the following categories:

2.1 Information You Provide Directly

• Account information: Phone number, email address, username, and password at registration.
• Profile data: Display name and profile photo if you choose to set them.
• Feedback: Any information you send to us via support or feedback channels.

2.2 Information Collected Automatically

• Audio data: To provide speech recognition and translation, we process audio from your device. Audio is processed in real time and we do not store your raw audio files.
• Device information: Device model, operating system version, device identifier, and IP address.
• Usage logs: Session timestamps, feature usage, and language selections.
• Location: With your permission, approximate location may be used to improve language accuracy.
• Translation history: Saved locally on your device so you can review and manage past captions.

We may use the information we collect to:

• Provide speech recognition and translation services
• Verify your identity and keep your account secure
• Save and manage your translation history
• Improve translation accuracy based on usage patterns
• Improve and develop our products and services
• Analyze usage to understand how our app is being used
• Detect, prevent, and investigate fraud or misuse
• Comply with legal obligations
• Send you important notices and product updates

We do not sell your personal information to third parties. We may share your information in the following circumstances:

4.1 With Your Consent

We will share your personal information with other parties only when you have given us explicit consent to do so.

4.2 Service Providers

We may share certain information with third-party service providers (e.g., AI recognition providers, cloud storage) to deliver our services. All such sharing is limited to what is necessary, and providers are required to maintain strict data protection measures.

4.3 Legal Requirements

We may disclose your information when required by law, court order, or government authority, or to protect the rights, property, or safety of CaptionFlow, our users, or others.

We employ a range of security measures to protect your information against loss, misuse, or unauthorized access:

• SSL/TLS encryption for all data in transit
• Encryption of sensitive data at rest
• Strict access controls and permission management
• Regular security audits and vulnerability scanning
• Data backup and disaster recovery procedures

Audio processing: We prioritize on-device processing. When cloud processing is required, audio is encrypted in transit and immediately deleted after processing — it is never stored.

Your personal information is stored in our data centers. If cross-border transfers are necessary, we will obtain your consent and ensure adequate protections are in place at the destination.

Depending on applicable law, you may have the following rights:

• Access: Request a copy of the personal information we hold about you.
• Correction: Ask us to correct any inaccurate or incomplete data.
• Deletion: Request deletion of your personal data, including translation history, in certain circumstances.
• Withdraw consent: Withdraw consent for any processing based on your consent.
• Data portability: Export your translation history in a portable format.
• Account deletion: Delete your account via Settings → Account Management. We will delete or anonymize your data thereafter.

To exercise these rights, use the in-app feedback feature or contact us by email:

We take the protection of children's personal information seriously. If you are under 18, please read this policy with your parent or guardian and obtain their consent before using our services.

We only use or disclose children's personal information as permitted by law, with verifiable parental consent, or when necessary to protect a child's safety.

If we discover we have collected personal information from a child without parental consent, we will delete it promptly.

Our app may include links or integrations with third-party services. When you use these services, they may collect their own information — please review their respective privacy policies.

The primary third-party services we use include:

• Speech recognition providers (Google, Azure, Amazon, etc.)
• Machine translation providers
• Cloud storage providers
• Analytics providers

We require all third-party providers to maintain strict data protection standards, but we cannot be responsible for their independent privacy practices.

We may update this Privacy Policy from time to time. When we make material changes, we will post a prominent notice in the app and seek your consent before changes take effect where required.

We encourage you to review this policy periodically. Your continued use of CaptionFlow after an update constitutes acceptance of the revised policy.

If you have any questions, comments, or concerns about this Privacy Policy, please contact us. We will respond within 15 business days.
