Terms of Use

Usage guidelines and content restrictions for Aletheia.

---

Intended Use

Aletheia is designed for educational purposes: understanding the etymology, historical context, and cultural evolution of language on general-audience websites.

---

Content Restrictions

Adult Content Websites

Aletheia is not intended for use on adult-tagged websites.

When the extension detects an adult content indicator (such as RTA labels or similar age-restriction metadata):

1. The extension automatically disables itself on that page
2. No data is sent to our servers
3. No logging occurs — not even the fact that the extension disabled itself
4. No user action required — this is automatic and silent

This ensures complete privacy on age-restricted sites while maintaining our focus on general-audience educational content.

How Adult Sites Are Detected

The extension checks for industry-standard content labels:

• RTA (Restricted to Adults) meta tags
• Similar age-verification metadata

Important: We do not maintain a blocklist of URLs. Detection is based solely on page metadata that the site itself provides.
