Newsletter Subscription Terms & Processing
When you voluntarily register your email address for the Cyber Briefing, the following statutory terms apply:
- Data Collected: Exclusively the email address provided by the subscriber (no phone numbers, national IDs, or sensitive data).
- Legal Basis (Art. 7, I LGPD & GDPR Art. 6(1)(a)): Explicit, informed, and unambiguous consent given upon form submission.
- Specific Purpose: Transmission of periodic cyber intelligence briefings, case law analysis, Observatory alerts, and academic course announcements.
- One-Click Unsubscribe (Instant Opt-Out): Every newsletter edition includes a mandatory, direct unsubscribe link in the footer. Revocation immediately deactivates and purges the address from active mailing lists.
- No Third-Party Sharing: Subscriber lists are strictly confidential and will never be sold, rented, leased, or shared with advertising networks or third-party brokers.
Local Cryptographic RAM Isolation
Our interactive utility for Digital Evidence Preservation (/en/preserve-evidence/) is engineered with rigorous technical isolation:
- Strict Content Security Policy (`connect-src 'none'`): The browser blocks all outgoing network transmission of evidence files or form inputs.
- Native SHA-256 Calculation: Cryptographic digests are computed locally using the browser's native Web Crypto API. No files or raw bytes are uploaded to remote servers.
- In-Memory Exports: Generated reports (.TXT and .JSON) are assembled into volatile local Blob objects, maintaining complete user custody.
Strictly Essential Technical Storage
This platform does not use tracking cookies, retargeting pixels (Meta Pixel/Google Ads), or invasive third-party analytics. Storage is strictly limited to:
Saves your visual interface preference (Light Mode ☀️ or Dark Mode 🌙) across pages and Observatory subdomains.
Records your acknowledgment of the privacy notice so it remains dismissed during subsequent navigation.
Statutory Telecommunications Log Retention
In compliance with statutory requirements under the Brazilian Internet Civil Rights Framework (Law 12.965/2014, Arts. 13 & 15), hosting infrastructure servers automatically log essential connection parameters (source IP address, timestamp, port number) strictly for network security, DDoS mitigation, and compliance with valid judicial subpoenas.
