Security & Trust
DRAFT — This page will update automatically once the lawyer-approved final text is uploaded from the admin panel.
At SemsTrend, trust is not a marketing slogan; it is an architectural decision. These are the safeguards we apply:
DATA TRANSMISSION
• All traffic is encrypted end-to-end with TLS (HTTPS); unencrypted connections are not accepted.
• Session cookies are marked httpOnly + secure + sameSite; browser scripts cannot access them.
IDENTITY AND ACCESS
• Access is available only to accounts on the authorized user list (allowlist).
• Access codes are stored as irreversible scrypt hashes — plain-text codes are never stored anywhere.
• Sessions are signed with HMAC-SHA256 and valid for 7 days. All sessions can be revoked instantly in bulk with a single central key (epoch).
• Only the founder can authorize a new user; every access change is recorded.
DATA STORAGE
• Data is stored on managed PostgreSQL infrastructure hosted in the European Union (Frankfurt).
• Database connections use encrypted channels; access credentials are kept in environment variables, not embedded in code.
• Every radar run is recorded in a traceable way with its source, quality, and decision chain (provenance).
PAYMENTS
• Payments are accepted only through the Apple App Store / Google Play. Your card details NEVER reach our servers.
• Subscription validation is performed server-side using the store receipt.
DATA POLICY
• Your data is not sold to third parties.
• KVKK and GDPR principles are observed; deletion requests are handled through the address on the contact page.
