Privacy Policy

Last Updated: Dec. 10, 2025

Multipaint is a collaborative drawing tool designed for real-time interaction. We respect your privacy and collect as little personal information as possible. This policy explains what we store, how we use it, and your rights as a user.

1. Information We Collect

1.1 Cookies

Multipaint uses small first-party cookies to remember your preferences and keep rooms functioning properly:

• mp_uid – A randomly generated anonymous device ID.
• username – The name you choose to display in rooms.
• color – Your chosen drawing color.

These cookies are not used for advertising, tracking across websites, or sharing with third parties. You may delete these cookies at any time in your browser settings.

1.2 Analytics Logs

Limited event data is logged to help improve the site and detect abuse. The log may include:

• Anonymous ID (mp_uid)
• Room joined
• Timestamps (join time, leave time)
• Basic technical events (e.g., room creation)

No personal information such as IP addresses, emails, or device fingerprints is stored in analytics logs beyond what is automatically contained in standard server logs.

1.3 User-Generated Drawings & Messages

Multipaint transmits drawings, image positions, and chat messages only to users inside the same room. This content is stored temporarily in memory while the room is active, and is cleared when:

• the room is empty,
• a user clears the canvas, or
• the server restarts.

We do not retain or archive drawings, images, or chat history once the room instance ends.

1.4 Uploaded Images

If you upload an image, the file is checked using AWS Rekognition to detect disallowed content (pornography, gore, violence, hate imagery, etc.). Only the moderation scan is performed; we do not store your images long-term.

If the image is allowed, it is transmitted temporarily to other users in the room in order to be displayed. It is discarded when the room ends.

2. How We Use Your Information

• Maintain your session in a drawing room
• Remember your preferences (username, color)
• Display drawings and actions to other users in your room
• Prevent abuse (spam detection, image moderation)
• Understand site usage (anonymous analytics)

Data may be processed on servers located in the United States. By using Multipaint, you consent to the transfer and processing of your data in the United States.

3. Third-Party Services

Multipaint uses the following external service:

AWS Rekognition

Used solely to detect prohibited content in uploaded images. Images are sent securely to AWS for moderation and immediately discarded after scanning. We do not use any other AWS features or store the image after moderation.

4. What We Do Not Collect

• Emails
• Passwords
• Location data
• Advertising identifiers
• Behavior across other websites

5. Children’s Privacy

Multipaint is intended for users aged 13 or older. If you are under 13, please do not use this service. We do not knowingly collect information from children under 13.

6. Data Retention

• Cookies: up to 1 year (local to your browser)
• Analytics logs: may be retained for service debugging
• Drawings/messages/images: only stored in memory while room is alive

7. Your Rights

• Clear your cookies at any time
• Request we delete analytics logs associated with your anonymous ID
