Overview. Margenao provides browser-based ecommerce calculators, educational articles and downloadable resources. This policy explains what information may be handled when you visit the site.
Calculator inputs. Calculator values are processed in your browser to produce results. The site is not designed to collect or store the values you enter into calculators, and those values are not intentionally submitted to our Worker for calculation. Do not enter passwords, payment-card details, account credentials, customer names, addresses or other sensitive personal information.
Analytics. We use Cloudflare Web Analytics to understand aggregate site performance and usage. Cloudflare describes Web Analytics as using performance measurement data without analytics cookies, local storage or fingerprinting. The analytics beacon is served from static.cloudflareinsights.com and sends measurement data to Cloudflare. Documentation: https://developers.cloudflare.com/web-analytics/about/ and https://developers.cloudflare.com/web-analytics/data-metrics/data-origin-and-collection/.
Hosting and security. The website is hosted on Cloudflare infrastructure. Cloudflare and other service providers involved in delivering, maintaining or protecting the site may process technical information associated with a request, such as network and browser information, requested URLs, timestamps and security signals, subject to their applicable terms and policies. We do not use calculator inputs to build visitor profiles.
Cookies and advertising. Margenao does not currently display third-party advertising or use affiliate tracking links. Cloudflare Web Analytics is described above and does not use cookies for analytics. If and when Google AdSense is enabled, third-party vendors, including Google, may use cookies to serve ads based on a visitor's prior visits to this website or other websites. Google's advertising cookies may allow Google and its partners to serve ads based on those visits. Visitors can manage or opt out of personalized advertising through Google Ads Settings; additional information is available at aboutads.info and How Google uses information from sites or apps that use its services. Other ad networks or vendors, if used, will be identified here with links to their privacy and opt-out information where available. Advertising cookies or similar technologies will only be introduced when advertising is enabled, and any consent or privacy controls required by applicable law will be implemented before they are used.
External links. Articles and tools may link to marketplaces, software providers and other third-party websites. Those websites operate under their own privacy policies and terms. We do not control their data practices; review their policies before providing information or creating an account.
Children. Margenao is intended for people researching or operating ecommerce businesses and is not designed for children under 13. Please do not submit a child's personal information through the site.
Retention and security. We do not maintain user accounts or intentionally store calculator entries. Technical records held by infrastructure providers may be retained according to their service terms and operational requirements. No internet service can guarantee absolute security.
Policy changes. We may revise this policy when site features, service providers or legal requirements change. The updated date at the top indicates the latest revision.
Contact. For privacy questions or requests, contact support@margenao.com. Please do not include passwords, payment card details or other sensitive account information in your email.
