Privacy Policy

We collect the information you give us directly, such as your email address when you subscribe. We may also collect basic technical information such as IP address, browser, device, referral page, pages viewed, and approximate location derived from IP address.

If you sign up for the newsletter, we may send your email address and signup metadata to our email service provider so we can deliver Tokyo Brief and manage unsubscribe requests.

We also keep a temporary signup backup in our database, including your email, newsletter language, signup source, receipt time, destination groups, and delivery status. This lets us retry a failed transfer to our email provider. We remove these backup records after 30 days; they are not a separate mailing list. Contact us to request deletion of your signup backup as well as your provider record.

We use subscriber information to send Tokyo Brief, confirm signups, prevent abuse, improve deliverability, understand which pages and signup forms are working, and troubleshoot the service.

We use analytics and advertising pixels to measure page views, newsletter signup conversions, and campaign performance. Those tools may set cookies or receive browser identifiers according to their own policies.

For LinkedIn campaign measurement, we may share page activity, browser identifiers, an optional advertising click identifier, an optional IP address, and a one-way hashed email address after a successful newsletter signup. LinkedIn uses these signals to attribute and deduplicate campaign conversions according to its policies.

For X (Twitter) campaign measurement, we may share page activity, browser identifiers, an optional IP address and browser user agent, and a one-way hashed email address after a successful newsletter signup. We turn off the X pixel's automatic collection of email addresses typed into forms. X uses these signals to attribute and deduplicate campaign conversions according to its policies.

For Reddit campaign measurement, we may share page activity, browser identifiers, an optional IP address and browser user agent, and a one-way hashed email address after a successful newsletter signup. We turn off the Reddit pixel's automatic collection of email addresses typed into forms. Reddit uses these signals to attribute and deduplicate campaign conversions according to its policies.

We do not sell subscriber lists. We share information with vendors that help us run the newsletter, analytics, hosting, security, and customer operations. We may also disclose information if required by law, to protect the service, or as part of a business transfer.

Every newsletter includes an unsubscribe link. You can also reply to a Tokyo Brief email to ask us to update or remove your subscriber information. Some operational, security, and legal records may be retained where reasonably necessary.

We keep personal information only as long as needed for the purposes above, then delete, aggregate, or de-identify it when practical. No internet service is perfectly secure, but we use reasonable safeguards and limit access to systems that need it.

Tokyo Brief is written in English about Japan and may be operated using providers in multiple countries. By using the site or subscribing, you understand that information may be processed outside your country of residence.

We may update this policy as the product changes. The current version will always be posted on this page with its effective date.
