Thank you for using Ecom Profit Calculator ("we", "our", or "us"). This is a Microsoft Edge browser extension designed exclusively for online store owners, dropshippers and ecommerce entrepreneurs to calculate net profit, platform transaction fees, product margins and pricing strategies for their online selling listings. Your privacy is our top priority, and this document fully explains our data handling rules.
Critically Important: This extension NEVER collects, uploads, transmits or stores your store API keys, admin login credentials, store order data, customer personal information, platform billing details or any sensitive store backend data to external servers.
We also do not track your browsing history, collect IP addresses, or gather any personally identifiable user information for advertising or analytics purposes.
We only request the browser `storage` permission to save non-sensitive, user-customized preferences and calculation history locally on your own device only. No data leaves your browser. Saved local data includes:
This local storage only serves to let you review past product profit calculations and retain personalized settings, with zero third-party sharing or server upload.
This extension does not embed remote executable code, third-party tracking scripts, or connect to any e-commerce official APIs. All profit calculation logic runs fully offline within your Edge browser. It only lets you manually input your online store’s fee & cost figures for manual computation, with no automatic data sync to any external selling platform backend.
Upgrade licenses are processed via independent third-party processor Payhip. We cannot access or store your credit card, PayPal or checkout billing data; all payment security is managed by Payhip under their own privacy policy.
Our one-time purchase licensing tiers for online sellers:
• Free Tier: Basic profit & margin calculator (permanent free access)
• Basic License ($9.99 one-time lifetime): Unlock advanced calculation features
• Pro License ($19.99 one-time lifetime): Full access including batch product calculation, break-even analysis and reverse pricing tools
All plans are one-off purchases with no recurring subscriptions or auto-renewals.
The only integrated third-party service is Payhip for license checkout. No other analytics, ad tracking, or data-sharing partners are integrated into this Edge extension.
This tool is built exclusively for adult ecommerce merchants and business operators aged 18+. We do not knowingly collect data from minors under 13 years of age, and will remove relevant local data traces upon user request.
You may clear all locally saved extension data at any time via your Edge browser’s extension management settings or by clearing browser local storage data. Since no user data is sent to our remote servers, there is no centralized database of your information to submit deletion requests for.
We may revise this privacy policy occasionally to comply with regulatory requirements or product function updates. All revisions will be published to this GitHub-hosted page with an updated "last updated" timestamp.
For any privacy-related inquiries or concerns, please reach out via the developer contact email submitted within your Edge extension developer dashboard.
