Your Vercel app deploys on every merge. Its privacy policy is still on version one.

Open your Vercel dashboard and look at the deployments list on your production project. Then open your privacy policy and find the date it was last changed. On most products the first list grew this week, and the second date is somewhere around launch.

Those two numbers are produced by the same codebase. Vercel exists to make the first one grow: connect a Git repository once, and every push gets a preview deployment, every merge to the production branch goes straight to production 1. Deploying is no longer something your team schedules; it happens as a side effect of merging. The second number has no pipeline behind it at all. Somebody has to remember that a deploy changed what the policy describes, and nobody's job is to remember that on a Tuesday.

This post is about closing that gap for apps deployed on Vercel specifically: what hosting there already obliges your documents to say, why the gap grows with every merge, and how to get your legal documents onto the same cadence as your deploys without adding a review step to anyone's week.

Does Vercel handle GDPR compliance for the apps it hosts?

No, and it does not claim to. The split of duties under GDPR is between a controller, who decides why and how personal data is used, and a processor, who handles it on the controller's instructions. For the app you deploy, you are the controller. Vercel is a processor: its Data Processing Addendum commits it to processing customer data only on your instructions, and to imposing substantially similar obligations on its own sub-processors 2.

That covers Vercel's side. Yours is everything the documents say. Article 13 of the GDPR requires you, the controller, to tell users why their data is processed, who receives it, and where it goes 3. Vercel cannot write that for you, because it depends on what your app does, and your app is the one artifact Vercel treats as opaque: it builds and serves whatever the repository contains.

So a team searching for "Vercel GDPR" usually finds the answer to the wrong question. Vercel's certifications and DPA make Vercel a defensible vendor choice. They say nothing about whether your privacy policy matches your product this week.

What does Article 13 put in your privacy policy the day you deploy on Vercel?

Before you ship a single feature, hosting on Vercel already touches two disclosures:

• Recipients. Article 13(1)(e) requires naming the recipients or categories of recipients of personal data 3. Your hosting provider receives every request your users make, so it belongs in that answer, at minimum as a category like "infrastructure and hosting providers". If you publish a sub-processor list for your own customers, Vercel belongs on it by name.
• Transfers. Article 13(1)(f) requires disclosing that personal data leaves the EEA and naming the safeguard the transfer rides on 3. Vercel's DPA places its primary processing facilities in the United States. For transfers from the EEA, the UK, and Switzerland it points at the 2021 Standard Contractual Clauses, the EU's standard contract terms for moving personal data out 2. If you have European users, your policy has to say this transfer happens.

A customer-facing app on a Hobby account has a problem no policy wording fixes. Vercel's DPA applies by its own terms to customers on the Pro and Enterprise plans 2. On Hobby there is no processor contract in force at all, and GDPR requires one: a binding contract with specific mandatory terms, Article 28(3) 3. If that is your setup, upgrade to a covered plan first; the policy text can wait.

The first check I would run is one text search. Open your privacy policy and search for "Vercel", then for "hosting". If neither appears and the policy claims to list who receives user data, you have found your first correction, and no feature work caused it. The policy was incomplete on day one.

Why do the documents drift once shipping is continuous?

Because the review model most teams inherit assumes releases are events. A policy gets written at launch, then revisited when a lawyer is engaged, a customer asks, or something goes wrong. That model was already strained when releases were monthly. On Vercel, where the release is the merge 1, it produces a document that is outdated by an unknown amount at any given moment.

The changes that matter rarely announce themselves. They ride ordinary pull requests:

• An analytics or session-replay snippet goes into the layout. New recipient, and often a new transfer.
• Signup starts asking for a phone number. If your policy enumerates what you collect, and most do, that list is now incomplete.
• A support widget, a payment provider, an email API. Each one a vendor your users' data now reaches.
• A feature starts sending user content to an LLM API. New recipient, new purpose, and new questions about automated processing.

None of these feel like legal events to the person merging them. Each one makes a sentence in your privacy policy false, or reveals a sentence that was never there. And in a team shaped around Vercel's workflow there is no release train where a legal review could sit. Whoever owns the documents never sees the diff.

If you are running a customer-facing app on Vercel, you need every merged pull request checked against what your privacy policy, terms, and sub-processor list currently claim, at merge time, not at the next annual review. Otherwise every deploy quietly widens the gap between what you publish and what you do, and the moment it surfaces is chosen by whoever finds it: a customer's procurement team, an auditor, or a regulator reading your policy next to your network tab.

How does continuous compliance for a Vercel app work?

Lawcel, the product we build, is a compliance tool that watches the places your product changes and flags what that means for your legal documents. The reason it pairs well with Vercel is that Vercel already made the pull request the unit of shipping 1, and Lawcel attaches to that same unit. Connect the GitHub repository Vercel deploys from, and every pull request gets a second read alongside the preview. That read asks three things: what kind of feature this is, what kind of data it touches, and whether anything in it changes what your Privacy Policy, Terms, or sub-processor list must say.

When a pull request changes something disclosable, a case opens in Lawcel: a plain-language summary of what changed, a risk score, the documents affected, and suggested text for the specific clause, linked back to the pull request that triggered it. You approve or reject each suggestion, and nothing publishes to your live documents until you do. When a pull request only refactors, restyles, or rearranges, no case opens, because nothing about it is disclosable. Most merges are like that, and the system stays silent through them.

The result is the property your deploys already have, applied to your documents: they move when the product moves, and only then. No scheduled review, no standing meeting, no one rereading the whole policy because something might have changed somewhere.

How do you connect a Vercel app to Lawcel?

Nothing changes on the Vercel side. There is no marketplace integration to install, no build step, no environment variable. Vercel keeps deploying exactly as before, and Lawcel never touches your Vercel account or your deployments.

The connection is the repository:

1. Find the Git repository your Vercel project deploys from. You picked it when you created the project 1.
2. Connect that repository to Lawcel's GitHub App: sign up, connect GitHub, and select the repository.

Because the connection is a GitHub App, only GitHub repositories are connectable today; a Vercel project deploying from GitLab, Bitbucket, or Azure DevOps is not. And because the monitoring reads pull requests, pushing commits straight to main gives it nothing to read. Vercel's own recommended flow, a PR into the production branch and a preview deployment before merge 1, is the flow this works best with.

If the app came out of v0, Vercel's AI app builder, you are already set up for this: v0's GitHub integration makes the repository the source of truth, commits every change, and ships through pull requests into a base branch 4. Connect that repository and the prompts get the same reading as any team's hand-written PRs.

My suggestion is to do the day-one check first: search your privacy policy for "Vercel" and for "hosting", and fix what is missing, because that gap exists before any code changes. Then connect the repository, so the next merge that adds a vendor, a data field, or an AI call is the last one that changes your product without anyone asking what it changes in your documents. That is what we built Lawcel to do, and for a Vercel app it starts with the repository you already deploy from.
