PILLAR 01
Our Core Privacy Commitments
eCAD Bridge is designed by hardware engineers, for hardware engineers. We understand that circuit schematics, internal component nomenclatures, stackups, and pin mappings represent mission-critical corporate trade secrets.
NO CAD HARVESTING
We never train AI or public models on your proprietary circuit geometries.
ZERO AD TRACKERS
No third-party ad networks or cross-site tracking pixels installed.
ENCRYPTED AT REST
All database models encrypted with AES-256 and HTTPS TLS 1.3 in transit.
PILLAR 02
Information We Collect
We collect only the minimal information required to authenticate engineers, deliver CAD outputs, and monitor platform health:
- Identity Information: Name, professional email address, and avatar URL provided through Google OAuth 2.0 when you register or sign in.
- Usage Parameters: Calculator inputs (e.g., trace width, dielectric height, copper thickness) processed ephemerally in server RAM.
- Community Activity: Editorial whitepaper comments, likes, and published public posts you explicitly submit to the platform.
- System Telemetry: Anonymized HTTP response status codes, latency percentiles, and browser user-agent strings for load balancing.

Protection of Proprietary CAD Netlists & Scripts
When using interactive tools such as FpGen, Sym Craft, or SKILL Labs:
memory
Ephemeral Memory Processing
Source code entered into the Cadence SKILL interpreter is executed within an isolated, sandboxed virtual interpreter session. Upon completion of AST evaluation and output generation, process memory is immediately scrubbed and deallocated. Scripts are not persisted to disk without your command.
PILLAR 04
Google OAuth Authentication Handling
eCAD Bridge implements Google SSO via the standard OAuth 2.0 PKCE flow. We request only basic read access (openid, email, profile).
We never access, request, or store your Google account password, Google Drive files, contacts, or calendar information.
PILLAR 05
Cookies & Local Storage
eCAD Bridge uses strictly necessary session cookies and local storage tokens:

Telemetry & Content Analytics
Our frontend telemetry ingestion pipeline collects aggregated interaction statistics (e.g., whitepaper scroll depth, video playback completion, and tool execution counts) to guide our editorial roadmap. All telemetry events are rate-limited, deduplicated, and stripped of personal identifying parameters before analysis.
PILLAR 07
Your Legal Privacy Rights (GDPR & CCPA)
Under international data protection frameworks, including the EU General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), you retain the following statutory rights:
Right to Access (SAR):
Obtain a machine-readable export of all data associated with your engineer profile.
Right to Erasure (Forgotten):
Permanently purge your account, comments, and telemetry tokens from our databases.
Right to Rectification:
Correct any inaccurate profile details directly from the User Profile console.
Right to Object:
Opt out of telemetry analytics by disabling browser performance tracking.
PILLAR 08
Data Retention & Contact Information
Account records are retained for as long as your engineering account remains active. If an account is inactive for more than 24 months, automated archival routines transition the record to cold storage pending permanent erasure.
