Data Guard Build

Answer a checklist about how your AI-generated app handles data — database access, input validation, secrets, access control, encryption, and privacy — grouped by category, and get a weighted risk score with the gaps that need fixing before real user data touches this app.

  • Weighted scoring across 6 data-security categories
  • Highlights your top data-risk gaps, worst first
  • All answers stay in your browser
Database access

All database queries use parameterized statements or an ORM

No string-concatenated SQL — this is the primary defense against SQL injection.

Database credentials use least-privilege access

The app connects with a role scoped to only the tables/operations it needs, not a superuser/admin account.

Row-level access control is enforced at the database or API layer

A user can only read/write rows they own — enforced server-side, not just hidden in the UI.

Input validation

All user input is validated server-side before use

Client-side validation alone is not enough — the server re-validates type, length, and format.

User-generated content is sanitized before rendering

Protects against stored XSS when displaying user-submitted text, names, or bios.

Secrets & config

Secrets and API keys are stored in environment variables, not hardcoded

No API keys, database passwords, or tokens committed in source code or exposed to the frontend.

No server-only secrets are bundled into frontend/client code

Frontend bundles are public — any key placed there is effectively public too.

Access control

Every data endpoint checks authentication before returning data

No endpoint returns user or business data without confirming who is asking.

Endpoints check authorization, not just authentication

Being logged in is not the same as being allowed to access this specific record — both are checked.

Data protection

All traffic is encrypted in transit (HTTPS/TLS everywhere)

Including internal service-to-service calls where practical, not just the public-facing site.

Sensitive data collection is minimized and has a defined retention/deletion policy

The app does not collect or retain more personal data than the product actually needs.

Privacy & disclosure

Error messages do not leak internal details or other users' data

Stack traces, database errors, or internal IDs are not exposed in API responses shown to users.

Logs and analytics exclude passwords, tokens, and sensitive personal data

Application logs are often less protected than the database — sensitive fields should never land there.

How it works

1

Answer the data-handling checklist

Rate each item across database access, input validation, secrets & config, access control, data protection, and privacy & disclosure as Yes, Partial, or No.

2

We calculate a weighted risk score

Each item is weighted by how directly it protects real user data, giving a transparent 0-100 score and a risk tier from critical to low.

3

See your top data-risk gaps

The five weakest, highest-weight gaps are surfaced first — the specific things worth fixing before this app touches real user data.

Frequently asked questions

Does this scan my actual database or code?

No — this is a self-assessment checklist. It scores risk purely from the answers you provide and runs entirely in your browser; it does not connect to any database, API, or codebase.

Why is row-level access control weighted so heavily?

AI-generated apps commonly implement authentication but skip authorization — checking who a user is but not whether they should see this specific row. That gap lets one user read another user's data, which is why it carries a top weight.

What is the difference between authentication and authorization checks in this checklist?

Authentication confirms who is making the request; authorization confirms whether that specific user is allowed to access the specific data being requested. Both are checked separately because AI-generated code often implements one without the other.

Is a low score a reason to panic?

No — most AI-generated apps start with real data-handling gaps, especially around row-level access control and secrets in frontend code. The score is meant to focus a hardening pass before real user data is at risk.

How is this different from a security scanner or penetration test?

A scanner or pentest inspects real code, traffic, and infrastructure. This tool is a structured self-assessment checklist — faster and free, but only as accurate as your answers; it does not replace a professional security review before handling sensitive data at scale.

How We Compare

Lovable and Cursor help generate the database access code and API endpoints themselves, but neither scores whether that data handling is actually safe for real users. MVPHub gives a fast, structured self-assessment across the categories most often mishandled in AI-generated apps.
