Privacy Policy

Cave Studio Inc. ("we") handles personal information as follows when providing the Shield3D software, its product website and customer portal (the "Service").

1. Information we collect

1. Order and contract details: company name, department, contact name, email address, phone number, address and billing details
2. Payment details: card details are collected and held by our payment processor, Stripe; we do not store card numbers (we may receive limited details such as card brand and last four digits)
3. License activation details: license key, a PC identifier (a value derived from the operating system's device ID), PC name, operating system, app version, activation time and IP address
4. Website and portal usage: access logs (IP address, time, browser type) and cookies that keep you signed in
5. Support requests: emails you send us and any scan result files (such as report.json) you share with us

2. Information we do not collect

Shield3D scans files only on your own PC. The files you scan, and their contents, are never sent to us. VirusTotal lookups happen only if you configure your own API key; file hashes are then sent from your PC directly to VirusTotal, not through us.

3. How we use information

1. To process contracts and provide licenses and software
2. To manage activated PCs and prevent misuse
3. To bill and confirm payments
4. To answer questions and provide technical support
5. To send notices you need, such as definition updates and trial expiry reminders
6. To improve the Service (using statistics that do not identify individuals)
7. To comply with the law

4. Sharing with third parties

We do not share personal information with third parties without your consent, except where required by law.

• Server hosting: SAKURA internet Inc. (Japan); email delivery: Google LLC (United States, Google Workspace)
• The product website uses Google Fonts (Google LLC, United States); your browser sends your IP address and similar data to Google when you view the site

6. Security

We use encrypted connections (HTTPS), protected passwords and restricted staff access to prevent leaks and loss of personal information.

7. Retention

Records that the law requires us to keep (such as invoices and accounting records) are kept for the required period after your contract ends and then deleted. Other information is deleted when it is no longer needed for the purposes above.

8. Your rights
