For any question about this policy or about the personal information we hold, contact

Information we collect

Information collected automatically

When you visit the site, we automatically collect technical information about your device and how you use the site. This includes browser type, IP address, time zone, operating system, screen resolution, approximate location by country and city, the pages you view, the referring website or search term, and the date and time of your visit.

This information is collected through cookies, log files and similar technologies. We refer to it as device information.

Information you provide

When you submit a contact or quotation form, subscribe to our communications, or purchase a service, we collect the information you give us. This normally includes:

• Name and organisation — so we can address and route your enquiry
• Email address and telephone number — to respond to you
• Billing details — where an invoice or payment is involved
• The content of your message — the scope, question or requirement you describe

How we use it

We use the information you provide to respond to enquiries, prepare and issue quotations, run and administer engagements, issue invoices and confirmations, and maintain the business records we are required to keep.

We use technical information to keep the site working, understand which pages are useful, monitor performance and capacity, and identify misuse or fraudulent activity.

Where you have subscribed, we use your email address to send DEISO communications. You can unsubscribe at any time using the link in any message, or by following the instructions on our unsubscribe page.

Legal basis

Where data protection law requires a legal basis for processing, DEISO relies on:

• Performance of a contract — to prepare a quotation, run an engagement, and issue invoices
• Consent — for newsletter subscriptions and non-essential cookies, withdrawable at any time
• Legitimate interests — to respond to enquiries, secure the site, and understand how it is used
• Legal obligation — to retain accounting and tax records as Japanese law requires

Cookies and analytics

The site uses cookies to function correctly and to measure usage. Essential cookies keep the site working. Analytics cookies help us understand which pages are read and how the site performs.

We use Google Analytics for site statistics. Google processes this data on our behalf and its handling is governed by the Google privacy policy. You can prevent Google Analytics from collecting your data using the Google Analytics opt-out add-on.

You can also block or delete cookies through your browser settings. Doing so may affect how parts of the site work.

Who we share it with

We share personal information only where it is needed to run the business, and only with providers who process it on our behalf:

• Website and hosting providers — to operate dei.so
• Analytics providers — to measure site usage
• Email and communication providers — to send and receive correspondence and subscriptions
• Payment providers — to process payment where applicable

We may also disclose information where required by applicable law, to respond to a lawful request from an authority, or to establish or defend a legal claim.

International transfers

DEISO is based in Japan, and personal information is processed in Japan. Some of the providers listed above process data in other countries.

For visitors and clients in the European Economic Area and the United Kingdom, personal information transferred to Japan is protected under the European Commission’s adequacy decision for Japan, which recognises Japanese data protection law as offering an equivalent level of protection.

How long we keep it

We keep personal information only for as long as it serves the purpose it was collected for.

• Enquiries that do not lead to an engagement — kept while the enquiry is active and for a reasonable period afterwards
• Client and order records — kept for the duration of the relationship and then for the period Japanese tax and accounting law requires
• Subscriber records — kept until you unsubscribe
• Analytics data — kept according to the retention period set in the analytics platform

Your rights

Depending on where you are located, you may have the right to request access to the personal information we hold about you, ask for it to be corrected, ask for it to be deleted, object to or restrict how we use it, ask for a copy in a portable format, and withdraw consent you have previously given.

To make a request, email . We will respond within the period the applicable law requires. We may need to verify your identity before acting on a request.

Some records cannot be deleted on request where we are required to retain them, for example accounting records and correspondence forming part of a contractual relationship.

Security

DEISO takes reasonable technical and organisational measures to protect personal information against loss, misuse and unauthorised access. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

How DEISO handles client project data, confidentiality and access is set out separately in our data governance and security page.

Children

The site and DEISO services are intended for business use and are not directed at children. We do not knowingly collect personal information from anyone under 18. If you believe we have, contact us and we will delete it.

Changes to this policy

We may update this policy to reflect changes in our practices or for operational, legal or regulatory reasons. The current version is always published on this page.
