Data Protection Policy

As of: March 2026

Responsible: STP Professional Co., Ltd.

1. Purpose of This Policy

This Data Protection Policy describes the technical and organisational measures that STP Professional Co., Ltd. (hereinafter "SwissThaiPro") has implemented to protect personal data and confidential documents within the scope of the LTR Visa Service.

This policy supplements our Privacy Policy and our Terms and Conditions and is addressed both to our clients and to our internal team.

2. Data Protection Principles

SwissThaiPro adheres to the following data protection principles:

  • Data minimisation: We collect and process only the data that is genuinely necessary for the provision of our service.
  • Purpose limitation: Personal data is processed exclusively for the purpose for which it was collected – the application for the LTR Visa.
  • Storage limitation: Data is stored only as long as necessary for the respective processing purpose or as required by statutory obligations.
  • Integrity and confidentiality: We employ appropriate technical and organisational measures to ensure the security of data.

3. Technical Security Measures

3.1 Encryption

Data transmission:

All data transmitted between your browser and our website or document portal is encrypted using TLS 1.3 (Transport Layer Security). This applies to:

  • All website page views
  • The contact form
  • The registration and payment form
  • The document upload portal
  • All communication within the protected client area

Data storage:

Security-relevant data such as TOTP secrets for two-factor authentication are stored encrypted with AES-256-GCM (Advanced Encryption Standard with 256-bit key). Passwords are hashed with bcrypt and are not available in plain text.

Key management:

Encryption keys are stored separately from the encrypted data. Access to keys is restricted to authorised system administrators.

3.2 Document Storage

Storage location:

Client documents are stored on a self-hosted Nextcloud instance. Nextcloud is an open-source platform for secure file management. Documents are not stored with third-party providers such as Amazon, Google or Microsoft.

Security features:

  • Access exclusively via app password (Basic Auth) – no public share links
  • Regular security updates and patches
  • Regular backups of the database and documents

3.3 Access Controls

Client portal:

  • Individual login with email address and password
  • Password requirements: At least 8 characters
