Privacy Policy

Last Updated: July 2026

At MarginWize ("we", "our", or "us"), accessible from our website, protecting your personal privacy is one of our main priorities. This Privacy Policy outlines the types of information collected and how it is used.

1. Financial Data Privacy (No Server Logging)

MarginWize operates as a client-side utility platform. All numeric data entered into our calculators (e.g. costs, profit margins, sales tax amounts, ROI values) is calculated entirely within your browser using local JavaScript. We do not collect, store, or transmit your financial input figures to any external server.

2. Google AdSense & Third-Party Advertising Disclosures

We display advertisements provided by Google AdSense and third-party ad networks to keep our tools free:

• Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to our sites and/or other sites on the Internet.
• Users may opt out of personalized advertising by visiting Google Ads Settings.

3. Cookies and Local Storage

We use local browser storage (`localStorage`) solely to store user UI preferences, such as your chosen currency symbol ($ USD, € EUR, £ GBP, kr SEK) and theme preference (light/dark mode). You can clear your browser storage or disable cookies at any time through your browser settings.

4. Log Files and Web Analytics

Like standard web servers, our hosting environment logs basic non-personally identifiable technical information, such as IP addresses, browser types, Internet Service Providers (ISP), referring/exit pages, and date/time stamps for network performance and security audit purposes.
