GDPR Compliance Mapping

Lawful Basis for Processing

Article 6(1)(f) GDPR - Legitimate Interest

Conformo relies on legitimate interest as the lawful basis for processing analytics data:

  • Legitimate Interest: Understanding how users interact with the platform to improve user experience, detect technical issues, and optimize platform performance
  • Necessity Test: Page view analytics are necessary to achieve these legitimate interests
  • Balancing Test:
    • User Impact: Minimal (no cookies, no PII collected, no behavioral profiling)
    • Business Need: High (essential for platform improvement and stability)
    • Conclusion: Legitimate interest is appropriate; user rights not overridden

Alternative Basis: Article 6(1)(a) - Consent (if preferred by organization)

  • Cookie banner could be extended to include analytics consent option
  • Currently, cookieless analytics do not require consent under most interpretations

Data Subject Rights

Users have the following rights under GDPR:

  1. Right of Access (Article 15)
    • Users can request what data is collected
    • Response: Page view data (URLs visited, timestamps, anonymized)
  2. Right to Erasure (Article 17)
    • Users can request deletion of their data
    • Implementation: Contact Vercel support to request data deletion
    • Retention: Vercel Analytics default is 30 days
  3. Right to Object (Article 21)
    • Users can object to analytics processing
    • Implementation: Honor Do Not Track (DNT) browser setting, or disable via user preferences
    • Note: Vercel Analytics respects DNT by default
  4. Right to Data Portability (Article 20)
    • Limited applicability (aggregated, anonymized data)
    • Users can request export of their specific page view data

Data Minimization (Article 5(1)(c))

Vercel Analytics adheres to data minimization principles:

  • Only Collects: Page URLs, timestamps, referrer, device type (browser/OS)
  • Does NOT Collect:
    • Personal identifiers (names, emails, IP addresses)
    • User behavior across sites (no cross-site tracking)
    • Cookies or persistent identifiers
    • Form input data
    • Scroll depth or mouse movements

Data Retention

  • Vercel Default: 30 days
  • Configurable: Retention period can be adjusted in Vercel settings
  • Deletion: Automatic deletion after retention period expires
  • User Requests: Manual deletion available upon request

International Data Transfers

  • Vercel Location: US-based company
  • EU-US Data Transfers: Compliant via:

Security Assessment

Script Injection Protection

Risk: Third-party analytics scripts could introduce XSS vulnerabilities

Mitigation:

Current Status:

  • CSP configuration not explicitly set in codebase
  • If CSP is enforced via server headers or Vercel configuration, update required

Action Item:

  • Verify CSP configuration in Vercel dashboard
  • Add Vercel Analytics domains to CSP if enforced
  • Test analytics functionality after CSP update

Status: ACTION REQUIRED (if CSP is active)

Data Minimization

Privacy Policy Update Required

Current Status

The existing Privacy Policy and Cookie Policy may need updates to disclose Vercel Analytics.

Privacy Policy

Add section under “Data We Collect” or “How We Use Your Information”:

Analytics and Usage Data

We use Vercel Analytics to understand how users interact with our platform. 
This helps us improve user experience, detect technical issues, and optimize 
platform performance.

Data Collected: Page URLs visited, timestamps, referrer, and device type 
(browser and operating system).

Data NOT Collected: Vercel Analytics does not collect personally identifiable 
information (PII), IP addresses, or use cookies. Data is anonymized and 
aggregated.

Data Processor: Vercel Inc. (United States). Data is processed in accordance 
with Vercel's Data Processing Agreement and Standard Contractual Clauses.

Retention: Analytics data is retained for 30 days, after which it is 
automatically deleted.

Your Rights: You can object to analytics processing by enabling "Do Not Track" 
in your browser settings, or by contacting us at [privacy email].

Update “Cookies We Use” section:

Analytics

We do not use cookies for analytics. Our analytics provider (Vercel Analytics) 
uses cookieless tracking to respect user privacy while providing us with 
essential platform usage insights.

Action Items

  1. ✅ Document analytics data collection in ANALYTICS.md
  2. 📝 Update Privacy Policy with Vercel Analytics disclosure (recommended)
  3. 📝 Update Cookie Policy to clarify no analytics cookies used (optional)
  4. 📝 Review and sign Vercel Data Processing Agreement (if not done)
  5. 📝 Add Vercel to list of data processors in internal compliance documentation

Law Reference

Provvedimento Generale del Garante Privacy (10 giugno 2021)
Guidelines on the use of cookies and other tracking technologies

Assessment

Vercel Analytics Compliance:

  • ✅ No Cookies Used: Vercel Analytics does not set any cookies
  • ✅ Technical Necessity: Can be argued as technically necessary for platform operation
  • ✅ Privacy-Preserving: Anonymized, aggregated data only

Cookie Banner:

  • ✅ Existing cookie banner already implemented (CookieBanner component)
  • ✅ Covers any cookies set by other services (if applicable)

Consent Requirement:

  • ✅ Not Required: Since Vercel Analytics is cookieless and does not track users across sites, explicit consent is not required under most interpretations
  • ⚠️ Conservative Approach: Organizations may choose to include analytics in cookie preferences for full transparency

Status: COMPLIANT (cookieless tracking), OPTIONAL (explicit consent)

Testing Evidence
