Data we collect

  • Identity and contact details you submit (name, email, company, phone if provided)
  • Message content describing plants, systems, and timing
  • Technical logs such as IP address, browser type, and pages viewed when analytics cookies are accepted
  • Engagement records needed to perform and document professional work

Purposes and legal bases

We process data to respond to inquiries, prepare proposals, perform contracted reviews, meet accounting and legal obligations, and—only with consent or as otherwise permitted—improve the site via analytics. Grounds include contract performance, legitimate interests in operating a professional practice, legal obligations, and consent for non-essential cookies.

Retention

Contact-form messages are retained up to 24 months unless they convert into an engagement file. Engagement workpapers and correspondence are retained for at least seven years, or longer when required by law or professional standards. Analytics data follows the periods listed on our cookies page.

Sharing

We do not sell personal data. We may share data with IT hosting providers, email infrastructure, professional advisers under confidentiality, and—when you instruct us—your external auditors or lenders. Plant employee personal data encountered during fieldwork is handled under the engagement letter and minimized to what testing requires.

International transfers

Our primary operations are in Taiwan. If a processor stores data outside Taiwan, we take steps appropriate under applicable law, such as contractual safeguards, before transfer.

Subject to Taiwan personal data protection rules and other applicable law, you may request access, correction, deletion, or restriction of processing, and you may withdraw cookie consent at any time. Contact us at the email above. You may also lodge a complaint with the competent Taiwanese authority.
