1. Who We Are
dua9.online ("we", "us", "our") is a collection of free, single-purpose tools for writers, marketers and creators. This Privacy Policy explains how we handle information when you use our website and tools.
2. Information We Do Not Collect
We want to be very clear about this:
- We do not require you to create an account.
- We do not collect your name, email address, or any personal identifiers unless you voluntarily submit them via our contact form.
- We do not store, log, or have access to any API keys you enter into our tools (Anthropic, Groq, Replicate, or OpenAI keys).
- We do not store the content you generate using our tools on our servers.
3. API Keys — How We Handle Them
Several tools on dua9.online (Smart AI Writer, Content Humanisor, PinCraft AI, etc.) require you to provide your own API key from third-party services like Anthropic, Groq, or Replicate.
Here is exactly what happens with those keys:
- Browser-only storage: API keys are stored in your browser's session storage only — not localStorage, not cookies, not our servers. Session storage is automatically cleared when you close the tab.
- No server logging: Our servers act as a relay for some tools (e.g., Replicate image generation via
replicate-proxy.php). The proxy passes your key to the third-party API but does not log, store, or retain it in any way. - Per-visitor isolation: Each visitor's session is completely isolated. Your API key cannot be seen by, or used by, any other visitor.
4. Automatically Collected Data
Like most websites, our hosting provider (Hostinger) may collect standard server log data, including:
- IP address (typically truncated)
- Browser type and version
- Pages visited and time of visit
- Referring page
This data is collected by Hostinger for security and performance purposes and is subject to Hostinger's Privacy Policy. We do not use this data to identify individuals.
5. Cookies
dua9.online does not use tracking cookies, advertising cookies, or analytics cookies. The only storage mechanism used is session storage (for API keys, as described above), which is not a cookie and cannot be accessed by third parties.
6. Contact Form
If you submit our contact form, we collect your name, email address, and message content. This information is used solely to respond to your inquiry. We do not add you to mailing lists, share your information with third parties, or use it for any other purpose.
7. Third-Party Services
When you use tools that call third-party APIs (Anthropic, Groq, Replicate, OpenAI), your inputs are sent to those third-party services. We are not responsible for how those services handle your data. Please review their privacy policies:
dua9.online uses Google Fonts for typography. Google may collect standard request data. See Google's Privacy Policy.
8. Children's Privacy
dua9.online is not directed at children under 13. We do not knowingly collect any personal information from children.
9. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be indicated by a new "Last updated" date at the top. We encourage you to review this page periodically.
