1.Scope & Core Philosophy

At eCom Fees Calculator ("eComFees", "we", "us", or "our"), accessible at https://ecomfeescalculator.com, the privacy of our visitors and sellers is one of our foremost commitments.

This Privacy Policy document describes the types of information that are received, collected, or processed when you use our web application, calculators, and seller comparison directories, and how that information is handled.

2.Information We Do NOT Collect

Because we believe privacy is best guaranteed by not having sensitive data in the first place, our architecture enforces the following boundaries:

No Financial Credentials: We never ask for bank account numbers, credit card numbers, or marketplace OAuth login credentials.
No Remote Calculation Storage: When you input numbers into our eBay, Amazon, Etsy, or reverse profit calculators, these calculations execute strictly inside your local web browser via client-side JavaScript. We do not store your product costs, sale prices, or profit margins on remote servers.
No Personal Profile Tracking: We do not track you across other websites or construct personal advertising dossiers.

3.Information We May Collect Automatically

Like almost all websites, our hosting servers and delivery networks may log non-identifiable technical diagnostic data when your browser requests pages:

  • Server Access Logs: IP address (anonymized/truncated where required by law), browser user-agent, operating system, referring URL, timestamp of request, and HTTP status codes.
  • Voluntary Correspondence: If you send us a message via our contact form or support email, we will retain your email address and message contents solely to answer your inquiry and improve our calculators.

4.Local Storage & Cookie Usage

We prioritize localStorage over intrusive tracking cookies to enhance your experience:

Key NameTypePurposeRetention
themelocalStorageSaves your preferred UI theme ('dark' or 'light') to prevent screen flashing.Persistent until cleared
selectedCountrylocalStorageRemembers your default country region (e.g. US, UK, CA, AU) for localized fee currency.Persistent until cleared
calcHistorylocalStorage (Optional)Stores recent calculator comparisons locally on your device for quick reference.Persistent until cleared

You can delete your stored preferences at any time by clearing your browser's site data / cache.

5.Analytics & Infrastructure Partners

To maintain high uptime, detect DDoS attacks, and understand general traffic patterns (such as which marketplace calculators are most popular), we may utilize privacy-conscious aggregated analytics tools and CDN networks (such as Cloudflare or Vercel Edge).

These providers process aggregated statistics (page views, country of origin, bounce rates) without profiling individual browsing sessions or stitching cross-site identities.

6.GDPR, UK GDPR & CCPA/CPRA Privacy Rights

Depending on your location (such as the European Economic Area, the United Kingdom, or California), you are entitled to specific statutory rights regarding personal data:

EEA / UK Rights (GDPR)

  • Right of access to any personal data held
  • Right to rectification or deletion ("right to be forgotten")
  • Right to restrict or object to processing
  • Right to data portability

California Rights (CCPA / CPRA)

  • Right to know what categories of data are collected
  • Right to opt out of the sale or sharing of personal data (We do NOT sell data)
  • Right to non-discrimination for exercising rights
  • Right to correct inaccurate personal info

Because we do not store accounts, user profiles, or calculation entries, in most instances we hold no personal data associated with your browser. If you contact us via email, you may request deletion of your correspondence at any time.

7.Data Security & Retention

All web traffic is transmitted via high-grade modern Transport Layer Security (TLS/HTTPS 1.3 encryption). We implement strict security headers (Content Security Policy, X-Frame-Options, X-Content-Type-Options) to prevent unauthorized script injections or data interception.
