Where does the snippet go in a v0 project?

In the layout, inside the head. Ask the v0 chat to add the script there and paste the snippet. Those are the same steps the LexVibe dashboard shows for v0.

Do I have to publish again after installing it?

Yes. Changes only reach your visitors once you publish, so publish from v0 after the snippet is in place and then check the live site.

Does my v0 app need a cookie banner?

It depends on what the app loads. If it uses analytics, advertising pixels or other non-essential trackers and has visitors in the EU or the UK, you need consent before those scripts run, and a banner that only shows a notice without holding the scripts back does not meet that. LexVibe's banner blocks them until the visitor accepts. If the app only uses storage that is strictly necessary, consent is not required, but your privacy policy should still say so.

What happens when I add analytics, payments or AI to my v0 app later?

The documents describe the app as it was when they were generated, so run the check again after adding an SDK. For apps linked to a LexVibe account, the check lists the processing your hosted documents do not cover yet and recommends regenerating them.

Privacy policy, terms and cookie banner for your v0 app

v0 generates the interface, but the legal duties attach to whoever puts the app in front of visitors. Privacy information, consent before non-essential trackers and, if the app shows AI-generated content, an AI notice apply whatever tool produced the code. LexVibe works out what your project needs, drafts the documents and gives you a cookie banner to drop in.

What your v0 app needs

The duties depend on what the app does, not on the tool that built it. These are the usual three:

A privacy policy as soon as the app collects personal data, even just sign-up emails. It has to say who is responsible, what is collected and why, and what rights people have. GDPR
Consent before non-essential cookies and trackers for visitors in the EU and the UK, and in several US states an opt-out that honours Global Privacy Control. ePrivacy · CCPA/CPRA
A clear notice when people interact with AI or see AI-generated content. The transparency duties of Article 50 apply from 2 August 2026. EU AI Act

Each law has its own page with its applicability threshold and a link to its official text, so you can check every claim.

Install LexVibe in v0

In v0, LexVibe works through a single prompt: paste it in the chat and the assistant scans the project and asks for the three facts it cannot infer, then sends you to the free check to finish the setup and adds the snippet. You can also ask the chat to add the snippet to your layout yourself.

Paste one prompt in v0

1Paste this line in the v0 chat.
2The assistant fetches LexVibe's instructions, scans your project for what the code shows and asks only for what it cannot know: the owner, a contact email and your target markets.
3It sends you to the free check, which pre-fills what it detected and finishes the setup in three steps. Your app id comes from your own dashboard.
4Back in the chat, the assistant adds the one-line snippet with that id. Publish, then check the live site.

Read https://golexvibe.com/prompt and follow it to make this app legally compliant (privacy policy, terms, cookie banner, EU AI Act).

Or paste the snippet yourself

1In v0, ask the chat: «add this script to the layout, inside the <head>».
2Paste the snippet.
3Publish to Vercel from v0.

The same line works on every platform:

<script src="https://golexvibe.com/v1/lexvibe-widget.js" data-lexvibe-app="YOUR_APP_ID" defer></script>

Create your app in the dashboard to get your own app id in place of YOUR_APP_ID. It is free to start.

What you get

Privacy policy and terms, hosted at a public URL and updated when regulations change.
A cookie banner that blocks non-essential scripts until the visitor accepts, honours Global Privacy Control and records consent.
An AI-content notice and an EU AI Act risk classification, if your app shows AI-generated content.
A cookie policy only when your site really uses non-essential trackers, so you never publish filler.
