Halftone Maker - Privacy Policy

1. Introduction

Halftone Maker (the "Service") respects your privacy and is committed to protecting your personal information. This Privacy Policy explains what information is collected in connection with your use of the Service and how it is handled. By using the Service, you are deemed to have agreed to this Privacy Policy.

2. Information We Collect

Client-Side Processing

Currently, all image processing in the Service is performed within your browser (client-side), and your image data is never uploaded to our servers.

We may store your work using IndexedDB in your browser. This data is stored on your device and is not accessible to the Service operators.

Preset Sharing Information

When you use our preset sharing feature, we collect and store the following information on our servers:

• Preset name
• Parameter settings for the preset

This information is stored in Redis (a database service) and is accessible to anyone who has the share token/link.

Contact Form Information

When you use our contact form, we collect the information you provide, including your email address and the content of your message. This information is processed and transmitted using Resend, a third-party email service provider.

Automatically Collected Information

• We use Vercel event tracking to collect usage statistics such as errors and operation counts within the application.
• We use Google AdSense, which may collect information for ad delivery.
• We use cookies and localStorage for site routing control.

3. How We Use Information

The collected information is used for the following purposes:

• Providing and improving the Service and user experience
• Enabling the sharing of user presets with others
• Responding to your inquiries submitted through the contact form
• Improving site functionality and analyzing performance
• Displaying and customizing advertisements
• Identifying and resolving technical issues

4. Data Retention

• Data stored in IndexedDB is retained until you delete it through the application. If you do not delete it, the data will be stored according to your browser's specifications. You can also delete this data through your browser's "Delete site data" feature.
• Shared presets are stored in Redis for the period specified in the user interface at the time of sharing. After this period expires, the data is automatically deleted.
• Contact form submissions and associated personal information are retained for the purpose of responding to your inquiries and may be stored for a reasonable period to maintain communication history.
• Currently, there is no feature for uploading images to the server. If this feature is implemented in the future, this policy will be updated.
