1. Introduction

This Cookie Policy explains how Issei ("Issei", "we", "us") uses cookies and similar technologies, such as browser local storage, on the website issei.ai (the "Website"). It describes what these technologies are, which ones we use, why we use them, and how you can control them.

This policy should be read together with our Privacy Policy and our Legal Notice. It is provided in accordance with EU Regulation 2016/679 (GDPR), the Spanish Organic Law 3/2018 (LOPDGDD) and Article 22 of the Spanish Law 34/2002 on Information Society Services and Electronic Commerce (LSSI-CE).

Issei is a company based in Barcelona, Spain. For any question about this policy you can contact us at hi@issei.ai (English) or hola@issei.ai (Spanish).

2. What Are Cookies and Similar Technologies

Cookies are small text files that a website places on your device when you visit it. They allow the website to recognise your device and to store certain information about your preferences or past actions.

We also use browser local storage, which is a mechanism that lets the Website store information in your browser. Unlike cookies, information in local storage is not automatically sent to a server with each request and remains stored until it is deleted.

3. Consent and How Analytics Are Loaded

When you first visit the Website, a cookie-consent banner is displayed. No analytics cookies are set and no analytics technology is loaded until you give your consent through that banner.

  • If you accept, we load Google Analytics 4 and the associated analytics cookies are set.
  • If you reject, no analytics cookies are set and Google Analytics is not loaded.

Strictly necessary technologies, and the storage of your consent choice itself, do not require consent and are always active.

We do not use advertising cookies or third-party marketing cookies of any kind.

4. Storage of Your Consent Choice

Your consent decision is stored in your browser's local storage under the key "issei-cookie-consent". This is strictly necessary to remember your choice and to avoid showing you the banner on every page. It is not a cookie, it is not transmitted to any server, and it has no expiry date; it remains until you clear it.

5. Cookies and Technologies We Use

The following table lists the cookies and local storage items used by the Website. Analytics cookies are only set after you accept them through the consent banner.

_ga_WVN3MCVXWBGoogle Analytics (third party)Analytics cookiePersists session state for the analytics property (container G-WVN3MCVXWB). Set only after consent.Approximately 1 year

6. Analytics Details

We use Google Analytics 4 (measurement ID G-WVN3MCVXWB) to understand how visitors use the Website, on an aggregated and statistical basis, so that we can improve it. Google Analytics is only activated after you accept analytics cookies through the consent banner.

7. How to Withdraw or Change Your Consent

You can withdraw or change your consent at any time. To do so, clear the "issei-cookie-consent" entry from your browser's local storage (for example, through your browser's site-data or privacy settings for issei.ai); the consent banner will then be shown again on your next visit and you can make a new choice.

You can also manage cookies directly through your browser. Most browsers let you block or delete cookies and view the cookies stored for a site. The relevant controls are usually found in the browser's privacy or security settings. Please note that blocking strictly necessary technologies may affect the correct functioning of the Website.

For guidance on managing cookies in common browsers, consult the help pages of Google Chrome, Mozilla Firefox, Apple Safari or Microsoft Edge.

8. Changes to This Policy

We may update this Cookie Policy from time to time to reflect changes in the technologies we use or in applicable law. The version in force is the one published on the Website, identified by the "Last updated" date above.

9. Contact

If you have any question about this Cookie Policy, you can contact us at hi@issei.ai (English) or hola@issei.ai (Spanish).

Where the name comes from

In Japanese, issei is the first generation: those who left their country and started from scratch in another. The ones who do the hard work so whoever comes next can build on top.

The symbol is , “one”, the first stroke you learn to write. It felt like the right name for something that takes on the work nobody wants to repeat twice.
