Privacy Policy – MARK Caption

Last updated: December 2025

1. Overview

MARK Caption (“we”, “our”, “us”) respects your privacy and is committed to protecting it. This Privacy Policy explains how information is handled when you use our AI-powered caption generation platform.

We are committed to:

  • Transparency
  • Minimal data handling
  • Responsible AI usage

We do not maintain user accounts, do not store uploaded images in a database, and do not sell personal data.

2. Information We Process

Images You Upload

  • When you upload an image, it is temporarily processed to generate captions and hashtags.
  • The image is sent to a trusted third-party AI service for inference.
  • Images are not stored in a database by MARK Caption after processing.

User Inputs

  • Optional inputs such as caption tone, style, or custom instructions are processed only to generate the requested output.
  • These inputs are not saved to a user profile or database.

Logs

  • Minimal technical logs (such as error logs or request metadata) may be generated temporarily for debugging and system monitoring.
  • These logs do not include stored images or personal user profiles.

3. How We Use Information

We use processed data only to:

  • Generate image captions and hashtags
  • Improve platform performance and reliability
  • Monitor system health and prevent misuse

We do not:

  • Train our own AI models using uploaded images
  • Use uploaded content for advertising or profiling
  • Store images for future reuse

4. Third-Party AI Services

MARK Caption relies on trusted third-party AI providers to generate captions. These providers process images and text inputs according to their own privacy policies and do not operate under MARK Caption’s control. We recommend reviewing the privacy documentation of the AI provider you interact with.

5. Data Retention

  • Uploaded images are processed temporarily and are not intentionally retained by MARK Caption.
  • We do not maintain a persistent image or user database.
  • Any temporary logs are retained only as long as necessary for system operations.

6. Security

We apply standard security practices: HTTPS encryption for data in transit and a serverless, minimal-storage architecture to reduce exposure. However, no online system is completely risk-free. Users are advised not to upload extremely sensitive or personal content.

7. Children’s Privacy

MARK Caption is not intended for users under the age of 13. We do not knowingly collect personal data from children.

8. Responsible Use & Disclaimer

MARK Caption provides AI-generated outputs to assist users, not replace human judgment. Generated captions may contain inaccuracies — users should review and edit outputs before public use. MARK Caption is an experimental AI platform and outputs should be used responsibly.

9. Changes to This Policy

This Privacy Policy may be updated periodically. The “Last updated” date will reflect the most recent revision.
