What we collect

  • Your email address
  • The language you chose (English or Japanese)
  • When you signed up, when you confirmed, which page you signed up from, and the wording you agreed to (its version and full text)
  • When we last sent you an issue of the newsletter
  • Records of failed deliveries, spam reports and of addresses we must no longer send to
  • Your IP address, only to stop large numbers of sign-ups from one place. It is not stored as it is: a converted value that does not show the address as is is kept for one hour and then deleted automatically.

What we use it for

  • Sending the newsletter. When you sign up, you agree to this: “I agree to receive AI Making in 10 Minutes by email.”
  • Confirming your sign-up and handling unsubscribes
  • Not sending again to addresses that bounce, that reported our mail as spam, or that unsubscribed
  • Preventing misuse of the sign-up form
  • Keeping a record of your consent, as required by Japan's Act on Regulation of Transmission of Specified Electronic Mail and Act on Specified Commercial Transactions

We do not use your information for anything else.

Sharing

We do not give your information to third parties without your consent, except where the law requires it.

Service providers (including providers outside Japan)

To store the list and send the mail, we entrust the handling of your information to these providers:

  • Cloudflare, Inc. — runs the sign-up service and stores the list and the records of addresses we no longer send to
  • Resend — delivers the emails and tells us about failed deliveries and spam reports

Both are businesses based in the United States (Cloudflare and Resend). Your information may be handled in their data centres, which are located in various countries, including the United States. We exercise necessary and appropriate supervision over these providers. For information on the personal-information protection system of the United States, see the materials published by Japan's Personal Information Protection Commission (ppc.go.jp). If you ask, we will tell you about the measures these providers take.

Records of sending (for example, delivery logs) may remain in these providers' systems for a certain period.

How the newsletter is sent

The newsletter is sent from mail.hiromiishino.com. Replies are handled by Trimora Inc.’s contact desk ([email protected]). We do not track email opens or link clicks.

If an email bounces or is reported as spam, we remove the address from both the Japanese and English mailing lists. To make sure we do not send to it again, we keep the address, the reason and the date for as long as we operate the newsletter. We use this record only to avoid sending to that address. An address stopped this way is not signed up again automatically; if you would like to resume receiving the newsletter, please contact us.

How long we keep it

  • While you are subscribed, we keep your information.
  • A sign-up that is not confirmed is deleted automatically after 48 hours.
  • When you unsubscribe, your address is removed from the list at once. The record of your consent (including your email address) is kept for 3 years (1,095 days) from the last day we sent you the newsletter (from the day you confirmed, if you never received an issue), and is then deleted automatically.
  • The note that a particular issue has been sent to you (so that it is never sent twice) is deleted automatically after 35 days.
  • Records of addresses we must no longer send to are kept as described above.

How to unsubscribe

Every issue of the newsletter has an unsubscribe link at the bottom: open it and press “Unsubscribe”. The Japanese and English editions are stopped separately. You can also ask us at [email protected] or through the contact page.

Keeping it safe

Communication with this site is encrypted with HTTPS, only the people who need to can access the list, and we collect only the information listed above (apart from the sending records that may remain with our providers, as described above).

Your requests

You may ask us to disclose, correct, stop using or delete the personal information we hold about you. These requests are free of charge, and you may ask for disclosure in electronic form. Please write to [email protected] or use the contact page; after confirming that the request comes from you, we will respond without delay. Questions and complaints about how we handle your information are accepted at the same contact.

Records we are required by law to keep (such as the record of your consent to receive the newsletter) cannot be deleted until that period has passed.

Changes

If we change this policy, we will show the new version on this page.
