django-compliance-shield 1.1.0

Drop-in Django library for global privacy compliance: DPDP, GDPR, CCPA, FCRA. Field-level encryption, consent management, DSR tracking, breach notification, and data retention — all via a single decorator.

django-compliance-shield

Drop-in Django library for global privacy compliance. One decorator. Full DPDP, GDPR, CCPA, FCRA compliance.

---

What it does

Add one decorator to your model. The library handles everything else.

from compliance_shield.decorators import sensitive_field

class UserProfile(models.Model):
    data_region = models.CharField(max_length=10, default='IN')

    @sensitive_field(field_type='pan', jurisdiction_field='data_region')
    class pan_number:
        pass

    @sensitive_field(field_type='ssn', jurisdiction_field='data_region')
    class ssn_number:
        pass

That is all you write. The library automatically creates:

Created	What it does
_pan_number	Encrypted storage field (Fernet, regional key)
pan_number_index	Blind index for search without decryption
pan_number	Property — decrypts on get, encrypts on set
pan_number_masked	Property — e.g. ******1234F
Access log entry	Every read logged to SensitiveDataAccessLog

---

Features

Encryption

• Field-level Fernet encryption with separate keys per jurisdiction
• Blind index for searching encrypted fields
• Auto-masked property (field_masked)
• Key rotation via python manage.py rotate_keys
• MultiFernet supports zero-downtime key rotation

Consent Management

• ConsentRecord stores exact text shown, version, IP, timestamp
• Consent gate middleware — redirects to consent page if required consents missing
• Withdraw consent — triggers DataDeletionRequest automatically
• Privacy settings page — users manage all consents in one place

Data Subject Rights

• DataSubjectRequest handles all rights across all jurisdictions
• Auto-calculated deadlines: IN=30d, US access=45d, FCRA=30d, EU=30d
• High-sensitivity requests require identity verification
• DSR confirmation email sent automatically

Data Retention

• 29 retention policies seeded out of the box
• Daily enforcement: python manage.py enforce_retention
• DataRetentionLog — immutable audit trail of every enforcement action
• Legal hold flag prevents deletion of records under investigation

Breach Notification

• DataBreachRecord tracks every breach
• Authority notification deadlines per jurisdiction (72h IN/EU/UK/US, 30d AU)
• Admin dashboard shows overdue notifications in red

Compliance Middleware

• Jurisdiction detection on every request
• Security headers: X-Data-Region, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, Strict-Transport-Security

Django Admin

• Admin registration for all 7 compliance models
• Bulk actions: mark DSR in progress / completed, mark breach contained / resolved
• Consent records and access logs are permanently read-only

What's new in v1.0.0

1. Jurisdiction control — enable only the countries you need

COMPLIANCE_SHIELD = {
    # Only activate India and USA compliance.
    # Consent gate, retention policies, DSR types, and breach deadlines
    # will only apply to these two jurisdictions.
    'ENABLED_JURISDICTIONS': ['IN', 'US'],  # None = all (default)
}

python manage.py compliance_setup will only seed policies for enabled jurisdictions. The middleware consent gate will only fire for users in enabled jurisdictions. The privacy settings page will only show DSR types relevant to enabled jurisdictions.

---

2. Email notifications — fully configurable

COMPLIANCE_SHIELD = {
    'EMAIL_NOTIFICATIONS': True,           # master switch (default: False)
    'EMAIL_FROM': '[e-mail]',     # defaults to DEFAULT_FROM_EMAIL

    # Who gets notified when a user submits a DSR
    'DSR_ALERT_RECIPIENTS': ['[e-mail]'],

    # Who gets notified immediately when a breach is recorded
    'BREACH_ALERT_RECIPIENTS': ['[e-mail]', '[e-mail]'],

    # Who gets the daily overdue DSR digest (from enforce_retention cron)
    'OVERDUE_DSR_RECIPIENTS': ['[e-mail]'],

    # Whether to email the user on DSR submit / complete / reject
    'DSR_USER_CONFIRMATION_EMAIL': True,
}

All notifications use Django's standard email backend. Silent fail — a misconfigured email backend will never crash the compliance system.

3. DRF support — works with React, Vue, mobile, and headless projects

# urls.py — use template views, API views, or both
urlpatterns = [
    path('compliance/', include('compliance_shield.urls')),         # template views
    path('api/compliance/', include('compliance_shield.api_urls')), # DRF API views
]

Available API endpoints:

Method	Endpoint	Description
GET	/api/compliance/consent/	Current consent status
POST	/api/compliance/consent/grant/	Grant one or more consents
POST	/api/compliance/consent/withdraw/	Withdraw a consent
GET	/api/compliance/dsr/	List my DSRs
POST	/api/compliance/dsr/submit/	Submit a new DSR
GET	/api/compliance/access-log/	Sensitive data access log
GET	/api/compliance/retention/	View retention policies
GET	/api/compliance/jurisdiction/	Current jurisdiction info

All endpoints require authentication. All return JSON.
