Mobile App Landing Page Privacy Evidence Pack Checklist: A Practical Guide for GDPR Compliance

Introduction

*Updated for 2026 compliance practices.*

If you operate a mobile app, your landing page is often the first touchpoint where users decide whether to download. It’s also where you collect personal data—through analytics, tracking pixels, and sign-up forms—making it a critical point for GDPR compliance. A **mobile app landing page privacy evidence pack checklist** helps you systematically gather and verify the documentation needed to demonstrate compliance. This guide provides a practical, step-by-step approach to building your evidence pack, from consent management to tag verification, using GDPRChecker’s scanning tools.

What Is a Mobile App Landing Page Privacy Evidence Pack Checklist?

A mobile app landing page privacy evidence pack checklist is a structured list of items that website owners and app marketers use to validate that their landing pages meet GDPR requirements for transparency, consent, and data protection. It covers everything from cookie banners and privacy policies to the behavior of third-party tags before and after user consent. The goal is to create a defensible record—screenshots, scan reports, configuration exports—that you can present to regulators or internal auditors. This checklist is a practical compliance topic for website owners validating consent, tags, and disclosures.

Unlike a generic website checklist, a mobile app landing page often includes app-store redirects, deep links, and mobile-specific tracking (like SDKs or measurement protocols) that require special attention. The evidence pack should prove that you collect consent before firing non-essential cookies, that your privacy policy is easily accessible, and that users can exercise their data subject rights.

Why You Need a Privacy Evidence Pack for Your Mobile App Landing Page

Regulators expect more than a privacy policy link. Under GDPR, you must be able to demonstrate compliance (Article 5(2) accountability principle). A privacy evidence pack serves as that demonstration. It shows:

• **Consent was freely given**: You didn’t use dark patterns or pre-ticked boxes.
• **Data collection was limited**: Only necessary tags fired before consent.
• **Disclosures were clear**: Users knew what they were consenting to.
• **Rights were respected**: Users could easily withdraw consent or request data.

Without an evidence pack, you risk fines and loss of user trust. For example, if a user complains that your landing page dropped Facebook Pixel before they clicked “Accept,” you need a scan report showing the opposite. This checklist helps you build that proof systematically.

Key Components of the Evidence Pack

Your evidence pack should include:

1. **Consent Management Platform (CMP) configuration export**: Screenshots or JSON exports showing the banner setup, consent categories, and vendor list.
2. **Pre-consent scan report**: A GDPRChecker scan showing no non-essential network requests before consent.
3. **Post-consent scan report**: A scan showing that tags fire correctly after consent.
4. **Privacy policy snapshot**: A dated copy of the policy linked from the landing page.
5. **Cookie declaration**: A list of cookies and their purposes, matching the CMP.
6. **DSAR process documentation**: Evidence of how users can submit requests and how you respond.
7. **Reject-flow test results**: Proof that rejecting all cookies actually blocks non-essential tags.
8. **Tag Manager trigger configuration**: Screenshots showing consent-based triggers.

Step-by-Step Implementation Guide

Step 1: Audit Your Current Landing Page

Start by scanning your mobile app landing page with GDPRChecker. The scanner checks for pre-consent network requests, banner behavior, and disclosure gaps. Run a scan without interacting with the cookie banner to see what fires by default. Note any third-party domains contacted before consent—these are potential violations.

**Example**: A fitness app landing page had Google Analytics and Facebook Pixel firing on page load, before the user saw the cookie banner. The scan flagged 12 pre-consent requests. The fix: configure Google Tag Manager to block those tags until consent is given.

Step 2: Implement or Review Your Consent Banner

Your cookie banner must: - Appear on the first visit (no scrolling required). - Offer equal “Accept All” and “Reject All” buttons. - Not pre-tick any non-essential categories. - Link to the privacy policy and cookie settings.

Use a CMP that supports Google Consent Mode v2 if you use Google services. This ensures tags adjust their behavior based on consent state. For more on banner requirements, see our cookie banner requirements guide.

Step 3: Configure Tag Manager for Consent

If you use Google Tag Manager, set up consent initialization and default consent states. For each tag, add a trigger exception that checks consent. For example, your Facebook Pixel should only fire if `ad_storage` consent is granted.

**Real-world example**: A SaaS company’s landing page had a “Sign Up” button that triggered a LinkedIn Insight tag. They added a custom event trigger that only fired after the user clicked “Accept All.” Post-fix scan confirmed zero pre-consent LinkedIn requests.

Step 4: Update Your Privacy Policy

Your privacy policy must be: - Linked from the landing page (usually in the footer and cookie banner). - Written in clear, plain language. - Include: data controller identity, purposes of processing, legal basis (consent for cookies), third-party recipients, retention periods, and user rights.

For a detailed breakdown, refer to our privacy policy requirements guide.

Step 5: Test the Reject Flow

Many sites correctly block tags on “Accept,” but fail when the user clicks “Reject All.” Use GDPRChecker to scan after rejecting all cookies. Verify that only strictly necessary cookies remain. If you see analytics or marketing requests, your CMP or tag triggers need adjustment.

**Edge case**: Some CMPs fire a “consent update” event on reject, but if your tags listen for the wrong event, they may still fire. Always test with a scanner.

Step 6: Document Everything

Take dated screenshots of: - The cookie banner on mobile and desktop. - The privacy policy page. - The CMP configuration dashboard. - GDPRChecker scan results (pre- and post-consent).

Store these in a secure, version-controlled repository. This is your evidence pack.

Common Mistakes and How to Avoid Them

Mistake 1: Pre-Consent Data Leakage

**Problem**: Tags fire before the user interacts with the banner. This is the most common violation. **Solution**: Use a CMP that blocks tags by default and only unblocks after consent. Verify with a scanner.

Mistake 2: Incomplete Privacy Policy

**Problem**: The policy doesn’t mention all third parties or lacks a cookie table. **Solution**: Regularly update the policy when you add new tools. Use a cookie scanner to generate an accurate declaration.

Mistake 3: Ignoring the Reject Flow

**Problem**: The “Reject All” button doesn’t actually block all non-essential cookies. **Solution**: Test reject flow with GDPRChecker after every tag change.

Mistake 4: No Evidence of Consent

**Problem**: You rely on the CMP’s dashboard but never export or screenshot it. **Solution**: Schedule monthly exports of consent logs and scan reports.

Mistake 5: Mobile-Specific Oversights

**Problem**: The landing page works on desktop but the mobile version has different tags or a broken banner. **Solution**: Scan both mobile and desktop versions. Check for responsive banner issues.

How to Validate Your Evidence Pack with GDPRChecker

GDPRChecker scans help verify pre-consent network requests, banner behavior, and disclosure gaps after changes. Here’s a validation workflow:

1. **Baseline scan**: Run a full scan before making changes. Save the report.
2. **Implement fixes**: Adjust CMP settings, tag triggers, or policy text.
3. **Post-fix scan**: Run another scan and compare. All pre-consent violations should be resolved.
4. **Reject-flow scan**: Use the scanner’s “reject all” simulation to confirm blocking.
5. **Schedule recurring scans**: Set up weekly scans to catch configuration drift.

**Example**: An e-commerce app landing page added a new chatbot widget. A scheduled scan caught that the widget loaded before consent. The team moved the widget script to fire on consent, and the next scan was clean.

Comparison: Manual Checklist vs. Automated Scanning

| Aspect | Manual Checklist | Automated Scanning (GDPRChecker) | |--------|------------------|-----------------------------------| | **Pre-consent detection** | Requires inspecting network tab manually | Automatic detection of all third-party requests | | **Banner behavior** | Must test on multiple devices | Simulates user interactions and checks banner compliance | | **Policy checks** | Manual review of policy text | Scans for required clauses and links | | **Evidence generation** | Screenshots taken ad-hoc | Dated, shareable PDF reports | | **Frequency** | Typically one-off | Can be scheduled for continuous monitoring | | **Human error** | High risk of missing requests | Systematic and repeatable |

While a manual checklist is a good starting point, automated scanning provides the consistency and evidence strength that regulators expect. For small businesses, combining both is practical—use the checklist as a guide and the scanner for verification. See our GDPR checklist for small businesses for a broader compliance framework.

Real-World Examples

Example 1: The Hidden Pixel A travel app landing page used a retargeting pixel from an ad network. The pixel was hardcoded in the HTML, bypassing the CMP. A GDPRChecker scan revealed it firing on page load. The fix: remove the hardcoded pixel and add it via GTM with consent triggers.

Example 2: The Broken Reject Button A fintech landing page had a cookie banner with a “Reject All” button, but clicking it only closed the banner—it didn’t block cookies. The scan showed Google Analytics requests persisting. The CMP configuration was corrected to call the `gtag('consent', 'update', {...})` function on reject.

Example 3: The Missing Policy Link A gaming app landing page had a beautiful cookie banner but no link to the privacy policy. The scanner flagged the missing disclosure. The team added a link in the banner and footer, and the next scan passed.

Implementation Checklist

Use this numbered checklist to build your mobile app landing page privacy evidence pack:

1. Scan the landing page with GDPRChecker before any user interaction.
2. Verify that no non-essential cookies or network requests fire pre-consent.
3. Check that the cookie banner appears immediately and is not dismissible without a choice.
4. Confirm “Accept All” and “Reject All” buttons are equally prominent.
5. Test the reject flow: after clicking “Reject All,” scan again to ensure only essential cookies remain.
6. Review the privacy policy for completeness: controller identity, purposes, legal basis, third parties, rights.
7. Ensure the privacy policy is linked from the cookie banner and footer.
8. Export your CMP configuration (screenshots or JSON) showing consent categories and vendors.
9. Document your tag manager triggers, proving tags fire only after consent.
10. Set up recurring GDPRChecker scans (weekly or after any tag change).
11. Store all evidence—scan reports, screenshots, policy snapshots—in a dated, secure location.
12. Review and update the evidence pack at least quarterly or when you add new tools.
