1. Zero-Upload Architecture & Document Privacy
Q Converter is built around local-first document processing. When you use the Windows desktop suite (Q Converter-Setup.exe), your PDF, Office, and image files are processed directly in your computer’s local memory without telemetry SDKs, analytics trackers, user accounts, or outbound file uploads.
When you use the interactive PDF workbench on this website, PDF files you select are processed strictly inside your browser’s local memory using client-side libraries (pdf-lib and pdf.js). Your documents are never uploaded to Q-CUBIC servers.
2. Website Hosting & Standard Server Access Logs
Like standard static websites hosted on the public internet, the web hosting provider or CDN serving these pages may automatically record routine HTTP request logs for security, abuse prevention, and uptime monitoring. Such technical logs typically include:
- IP address and approximate network origin
- Browser type, operating system, and referring URL
- Requested page or asset path and date/time of access
These technical delivery logs contain no document contents from the Windows app or the in-browser PDF workbench.
3. Cookies & Browser Storage
This website does not use advertising cookies, behavioral profiling, or third-party analytics pixels. Minimal browser localStorage access is used strictly on page load to keep the light-canvas theme consistent.
4. Third-Party Resources & External Links
To render web typography, this website loads font stylesheets from Google Fonts (fonts.googleapis.com and fonts.gstatic.com), which receive standard browser connection metadata when your browser fetches font files.
Pages on this site also link to external properties operated by Q-CUBIC or third-party platforms (such as q-cubic.com, YouTube, X, LinkedIn, Instagram, Facebook, Pinterest, and TikTok). Visiting those external websites is governed by their respective privacy policies.
5. Direct Support & Email Inquiries
If you email contact@q-cubic.com, Q-CUBIC receives your email address and any details you voluntarily send in order to respond to your inquiry or support request. We do not sell or rent contact information to third parties.
6. Children’s Privacy & Policy Updates
This website and software are not directed to children under the age of 13, and we do not knowingly collect personal data from children. Q-CUBIC may revise this Privacy Policy from time to time by updating the effective date on this page.
