3Meta Lead Ads & Social Platforms (Facebook & Instagram)
Stackfyra uses official Meta Advertising solutions (including Facebook & Instagram Lead Ads) to connect with business prospects interested in custom software development.
Meta Platform Compliance Statement:
When you submit your contact information via a Meta Lead Ad instant form, your data is transmitted directly to our secure infrastructure using the official Meta Graph API (v26.0) with cryptographic HMAC-SHA256 signature verification (x-hub-signature-256).
We only request information directly relevant to evaluating and discussing your engineering project.
We do not merge your Meta advertising responses with third-party data broker profiles.
You may request immediate deletion of any lead data captured via Meta Lead Ads at any time by contacting us at privacy@stackfyra.com.

5Security & Encryption Standards
Security is core to everything we engineer. We enforce multi-tiered defense mechanisms to protect personal and business data:
AES-256-GCM Encryption at Rest: Sensitive integration tokens, API secrets, and credentials are encrypted at rest with authenticated AES-256-GCM.
TLS 1.3 Encryption in Transit: All communications between your browser, our servers, and third-party APIs are encrypted with modern TLS 1.3 standards.
Role-Based Access Controls (RBAC): Administrative access to lead records is restricted strictly to verified, authorized team members with multi-factor authentication.
Strict Mutual NDAs: All custom software development is conducted under binding Non-Disclosure Agreements, safeguarding your proprietary business concepts.
