3. Third-Party AI Processing Providers

To provide our AI image processing service, we transmit your uploaded images to third-party AI service providers. These providers process the images according to their own terms of service and privacy policies. We select providers that maintain appropriate security measures, but we encourage you to review their policies:

• Images are transmitted securely using encrypted connections (HTTPS/TLS)

5. Information Sharing and Disclosure

We do not sell, rent, or trade your personal information to third parties. We may share your information only in the following circumstances:

• Service Providers: We share information with third-party service providers who perform services on our behalf, such as payment processing (Stripe), authentication, and hosting. These providers are bound by contractual obligations to keep your information confidential and use it only for the purposes for which we disclose it to them.
• AI Processing Providers: As described above, images are transmitted to AI processing providers solely for the purpose of generating outputs.
• Legal Requirements: We may disclose your information if required to do so by law or in response to valid requests by public authorities (e.g., court orders, subpoenas).

• Business Transfers: In the event of a merger, acquisition, or sale of all or a portion of our assets, your information may be transferred as part of that transaction. We will notify you via email and/or prominent notice on our Service of any change in ownership.

6. Data Security

We implement appropriate technical and organizational security measures to protect your information against unauthorized access, alteration, disclosure, or destruction. These measures include:

• Encryption of data in transit using TLS/SSL
• Secure authentication mechanisms
• Regular security assessments and updates
• Limited access to personal information by authorized personnel only

However, no method of transmission over the Internet or method of electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your information, we cannot guarantee its absolute security.

We retain your account information for as long as your account is active or as needed to provide you with services. If you request account deletion, we will delete your personal information within 30 days, except where we are required to retain certain information for legal, regulatory, or legitimate business purposes.
