Vivin app lda. ("VIVIN", "we", "us" or "our") uses cookies and similar tracking technologies on the website www.vivin.app and the VIVIN platform (collectively, the "Services"). This Cookie Policy explains what cookies are, how we use them, and your choices regarding their use.

1. What Are Cookies

Cookies are small text files placed on your device (computer, tablet, or mobile phone) when you visit a website. They are widely used to make websites work efficiently, provide a better user experience, and supply information to the website owners.

Similar technologies include web beacons, pixels, and local storage, which function in a comparable way. References to "cookies" in this policy include all such technologies.

2. Types of Cookies We Use

2.1 Strictly Necessary Cookies

These cookies are essential for the Services to function and cannot be disabled. They are set by the VIVIN API when you sign in to the platform, or when you unlock the gated market-data dashboard on this site. Nothing else on this site sets a cookie.

Cookie	Purpose	Duration
vivin_rt	Keeps you signed in to the VIVIN platform (httpOnly; sent only to the VIVIN API)	30 days
vivin_rt_admin	Keeps a separate signed-in session for the VIVIN admin backoffice	30 days
vivin_td	Remembers a device you chose to trust, so you are not asked for a login code every time	30 days
market-data-auth	Keeps the market-data dashboard on this site unlocked after you enter the access code	24 hours

2.2 Analytics Cookies

We do not use analytics cookies. VIVIN loads no Google Analytics, and no other analytics or measurement tag, on this site or in the platform.

2.3 Functional Cookies

We do not use functional cookies. Your language choice is kept in your browser’s local storage, and campaign attribution for the duration of a visit in session storage — neither is a cookie, and neither is sent to our servers. Clearing your browser’s site data removes both.

2.4 Marketing Cookies

We do not use marketing or advertising cookies. VIVIN loads no advertising partner tags, so no profile of your interests is built through this site.

3. Your Choices

We do not currently show a cookie consent banner. We will ask for your consent before setting any cookie that is not strictly necessary, and you can control cookies at any time through your browser settings (below).

Browser Settings

Most web browsers allow you to control cookies through their settings. You can set your browser to block or delete cookies. However, if you block strictly necessary cookies, some parts of the Services may not function properly.

4. Third-Party Cookies

Some cookies may be placed by third-party services embedded in our pages. We do not control these cookies. The relevant third party’s privacy policy governs their use:

Stripe (payment processing) - stripe.com/privacy

5. Data Retention

Cookie lifetimes vary as described in the tables above. Session cookies are deleted when you close your browser. Persistent cookies remain on your device for the period specified or until you delete them manually.

6. Updates to This Policy

We may update this Cookie Policy from time to time to reflect changes in technology, legislation, or our business practices. The "Last updated" date at the top of this page indicates when the policy was last revised.
