## 🔐 Security Limitations
|
|
|
|
### No Absolute Security
|
|
|
|
**UNDERSTAND THAT:**
|
|
- No cryptographic system is 100% unbreakable
|
|
- Implementation bugs may exist despite best efforts
|
|
- Social engineering and endpoint security remain vulnerabilities
|
|
- Quantum computing may eventually threaten current encryption
|
|
- Traffic analysis may reveal communication patterns
|
|
|
|
### User Security Responsibilities
|
|
|
|
**YOU MUST:**
|
|
- Keep your devices secure and updated
|
|
- Use strong, unique passwords
|
|
- Verify security codes through out-of-band channels
|
|
- Understand the risks of your communication environment
|
|
- Follow operational security (OPSEC) best practices

## 🏛️ Freedom of Speech Support
|
|
|
|
### Our Mission
|
|
|
|
SecureBit.chat is developed to support:
|
|
- **Article 19** of the Universal Declaration of Human Rights
|
|
- **Freedom of expression** and **right to privacy**
|
|
- **Resistance to censorship** and mass surveillance
|
|
- **Protection of journalists, activists, and dissidents**
|
|
|
|
### Ethical Use Commitment
|
|
|
|
We believe privacy and free speech are fundamental human rights, but:
|
|
- These rights come with responsibilities
|
|
- Freedom of speech does not include freedom from consequences
|
|
- Users must respect the rights and safety of others
|
|
- Illegal activity is never justified, regardless of privacy tools used
|
