Privacy Policy

1. Overview & Zero-Retention Architecture

Codes Hub (“we”, “our”, or “us”), operated as part of the PDF Hub web suite (usepdfhub.com), is engineered on a strict 100% client-side, zero-retention architecture. We respect your financial confidentiality and business privacy. Unlike cloud accounting platforms, Codes Hub does not require account registration and does not upload, store, inspect, or log your financial entries on any backend database.

2. Information You Enter Into Our Tools

When you use our PDF Invoice Generator, Proforma Quote Maker, Payment Receipt Generator, VAT Calculator, Profit Margin Calculator, or Loan Amortization Calculator, all inputs remain strictly inside your local web browser’s active memory:

• Business & Client Details: Company names, postal addresses, phone numbers, email addresses, and VAT/tax registration numbers are rendered directly into your PDF using client-side JavaScript (pdf-lib) and are never transmitted to our servers.
• Uploaded Company Logos: Any PNG or JPG logo you select is read locally via the browser FileReader API solely to embed it into your generated PDF and is discarded immediately when you close or refresh the page.
• Financial & Tax Figures: Line-item pricing, VAT rates, profit margins, and loan principals are computed locally on your device.

3. Automatically Collected Technical & Security Data

Like all standard websites, our hosting infrastructure and edge security provider (Cloudflare) process minimal, non-identifying technical metadata required to deliver web pages securely and prevent abuse, including anonymized IP addresses, browser user-agent strings, referring URLs, and HTTP request timestamps. These server logs are strictly used for DDoS mitigation, uptime monitoring, and security diagnostics and are never linked to your financial documents.

4. Advertising & Google AdSense Cookies

To keep Codes Hub free for businesses and individuals worldwide, we display advertisements served by Google AdSense (Publisher ID: ca-pub-2178634744284821).

• Third-party vendors, including Google, use cookies and device identifiers to serve ads based on a user’s prior visits to this website or other websites on the internet.
• Google’s use of advertising cookies enables it and its partners to serve ads to users based on their visit to codes.usepdfhub.com and/or other sites across the web.
• You may opt out of personalized advertising at any time by visiting Google Ad Settings (My Ad Center) or www.aboutads.info.
• For full details on how we and our partners use cookies, please review our Cookie Policy.

5. Embedded Widgets (?embed=1 Mode)

Third-party websites and blogs may embed Codes Hub calculators via our Developers iframe snippets. Even when accessed inside an embedded iframe on an external website, all calculations and PDF generation occur locally inside the visitor’s browser, and no document contents are shared with either Codes Hub or the embedding host site.

6. Your Rights Under UK GDPR & EU GDPR

If you are located in the United Kingdom or the European Economic Area (EEA), you hold statutory rights under the UK GDPR and EU GDPR, including the right of access, rectification, erasure, restriction of processing, data portability, and objection. Because Codes Hub does not collect or retain personal document data, there is no stored profile to export or delete; however, you may contact us regarding any privacy or cookie consent inquiry.

7. Children’s Privacy

Codes Hub is intended for general business, accounting, and educational financial calculations and is not directed at children under the age of 13 (or 16 in the EEA). We do not knowingly collect personal data from minors.

8. Policy Updates & Contact Information

We may update this Privacy Policy periodically to reflect regulatory, technical, or service changes. Any revisions will be posted on this page with an updated effective date. If you have questions about this Privacy Policy or our privacy-by-design architecture, please contact us at [email protected].
