Privacy policy
Last updated: 28 July 2026
Takumi Audit Bureau (“we,” “us”) respects your privacy. This policy explains how we collect, use, retain, and protect personal data when you visit appstreamx.digital or contact us about financial auditing engagements.
Data controller
Takumi Audit Bureau, 974 4th Street, 新西村区, 高知県, Japan. Email: hello@appstreamx.digital. Phone: +81-1-976-8367.
Data we collect
- Identity and contact details you submit (name, email, phone if provided)
- Inquiry content (engagement interest, preferred dates, entity information, message text)
- Technical data such as browser type and pages visited when analytics cookies are accepted
- Newsletter email addresses if you subscribe via the footer form
Purposes
We use personal data to respond to estimate requests, schedule scoping calls, administer engagements once contracted, send ledger notes you subscribed to, and — with consent — understand which journal articles are useful.
Legal bases
We process data based on your request to take steps toward a contract, our legitimate interest in operating a professional practice and securing the website, and consent where required for non-essential cookies or marketing notes.
Retention
Inquiry records are retained for up to 24 months if no engagement follows, unless a longer period is needed for legal claims. Engagement working papers follow professional retention standards applicable in Japan, typically seven years or longer where regulations require. Newsletter subscriptions are kept until you unsubscribe.
Sharing
We do not sell personal data. We may share data with IT hosting providers under confidentiality terms, with professional advisers when required, or with authorities when legally compelled. Confirmation procedures during audits may involve contacting banks or customers named in your records under a signed engagement — that processing is governed by the engagement letter, not solely this website policy.
International transfers
Our primary operations and storage are in Japan. If a processor stores data outside Japan, we take appropriate contractual and organisational measures consistent with applicable Japanese privacy requirements.
Your rights
Subject to Japanese law, you may request access, correction, deletion, or restriction of your personal data, and you may withdraw consent for optional processing. Contact us at the email above. You may also lodge a complaint with the competent Japanese authority.
Cookies
See our cookie policy for details on essential and analytics cookies and how to manage preferences.
Changes
We may update this policy and will revise the date above when we do.
