Privacy Policy

This Privacy Policy applies to the HandwritingEraser website, Handwriting Eraser, PDF Tools, account features, and related online services we may provide later.

We aim to collect and use information in a clear and restrained way, only as needed to provide the service, keep it stable, protect security, and improve the experience.

• Account information, such as email address, username, display name, avatar URL, and sign-in method.
• Uploaded content, such as images, PDFs, and temporary processing data needed to generate results.
• Usage information, such as browser type, device information, access time, basic logs, error records, and performance diagnostics.
• Session information, such as minimal cookies or session tokens used to keep you signed in and maintain page experience.

• Provide handwriting erasing, PDF tools, and account-related features.
• Generate processing results, maintain sign-in status, and sync account profiles.
• Detect and troubleshoot errors, improve stability, monitor abuse, and protect service security.
• Support future product logic for credits, quota management, or paid features if those features are added.

Uploaded files are used only to complete the processing request you initiate, such as handwriting erasing, PDF splitting, or PDF merging. We follow a default no-long-term-storage approach for user content.

During result generation and download delivery, original or result files may be cached briefly so the workflow can complete. After processing, delivery, or the temporary flow ends, those files are removed and are not retained as long-term content.

If we later add long-term history, team spaces, or any use of uploaded files beyond the current feature scope, we will update this policy and make that clear.

We use a minimal amount of logs and session information to maintain sign-in status, protect requests, troubleshoot system errors, and understand basic page operation.

We do not broadly collect unrelated behavior data for marketing purposes without clear notice. If more analytics or marketing tools are added later, this policy will be updated.

• You can view and update account profile fields such as username, display name, and avatar URL.
• You can stop using the service and may request account or personal data deletion once support capabilities are available.
• If you have questions about data processing, you can contact us through future public support channels.

We use reasonable technical and organizational measures to protect account information, session data, and upload flows, but no online service can promise zero risk.

This service is not specifically designed for independent use by minors. Avoid uploading documents that contain sensitive personal information, medical information, identity documents, or other high-risk content.

We may update this Privacy Policy as features, legal requirements, or service methods change. Updates will be reflected on this page, and material changes will be communicated where practical.

If you have questions about this Privacy Policy or want to learn more about account, uploaded content, or data processing practices, please contact us through future public support channels. A support email will be added here once available.
