Cookie policy

Provisional version, under legal review. Last updated: 4 November 2026.

1. What we use

The following items, strictly necessary for the kizunastories.com website to work, are stored on your device:

  • Your cookie choice: a local storage entry ("kizuna-cookie-consent") remembers whether you accepted or refused the measurement of our adverts, and when, for 6 months.
  • Tester link: if you open a tester link, a local storage entry ("kizuna-kids-tester") keeps its code for the demos.

These items are exempt from consent (Article 82 of the French Data Protection Act). The usage limits of Emma and the demos do not rely on a cookie: they use a technical fingerprint computed on the server from your IP address and browser (see the privacy policy). The website's typefaces, served by Google Fonts, set no cookie.

2. Measuring our adverts

To know whether our adverts on Facebook and Instagram bring visitors, the website uses:

  • Google Tag Manager (Google): a tool that loads the Meta pixel on the website. It does not set any cookie itself.
  • The Meta pixel (Facebook, Instagram): it receives the pages viewed, clicks on the buttons leading to Emma or to the free trial and browsing events (for example opening Emma's window), with your IP address and browser. It sets the "_fbp" cookie and, if you arrive from a Meta advert, the "_fbc" cookie, both kept for 90 days.
  • Where your visit comes from: if you arrive from an advert or a flyer, a session storage entry ("kizuna-visit-source") keeps the campaign, the arrival code and, if you arrive from an advert, the Meta or Google click identifier found in the address, to pass them on when you sign up from another page. It is erased when you close the tab.

These tools are loaded only with your consent. On your first visit, a banner offers two buttons that look the same, "Refuse" and "Accept". Until you answer, or if you refuse, neither Google Tag Manager nor the Meta pixel is loaded, and no browsing event is prepared for them. Your choice is kept for 6 months, then the banner asks you again. As long as you have not accepted, the website erases the "_fbp" and "_fbc" cookies if they are present. If you withdraw your consent, it erases them and reloads the page without these tools. Data received by Meta may be processed in the United States (see the privacy policy).

3. Changes

If we add another audience or advertising tool, it will be described here and loaded only with your consent, in the same way.

4. Your choices

You can change your mind at any time: this button opens the banner again, where you can accept or refuse the measurement of our adverts.

You can also delete data stored by your browser at any time from its settings. For any question: contact@happiness-institute.com.
