Privacy Policy

Last updated: 2026-10-25. This policy describes the current build, where advertising and third-party analytics are disabled.

Calculator inputs

Calculations run in your browser. The application does not send price, cost or campaign inputs to a server. No Etsy account connection, customer data or credentials are requested.

Optional local storage

Save scenario stores inputs and results on your device under maker-margin-scenarios-v1, only after you press Save. Up to three scenarios per calculator can be retained. Clear all saved scenarios removes this key. Clearing browser site data also removes it. No account backup or cross-device sync exists. CSV exports are generated locally.

Hosting and contact

Your hosting provider may process IP addresses, request URLs and technical logs to deliver and secure pages, even when calculator values stay local. The intended hosting provider is Cloudflare Pages. If deployed there, see Cloudflare’s privacy policy. Confirm the actual host before publication and revise this notice if it changes. Emailing the operator shares your message and address with the operator and their email provider.

Advertising and analytics

This build loads no advertising, analytics, third-party fonts or external scripts. If AdSense is enabled later, this notice must be updated to describe Google’s cookies and data use, available opt-outs and applicable privacy rights. Consent management and US state privacy choices must be configured and checked before ads are activated. A US audience does not prevent visitors from other regions.

Your choices and requests

Use the calculators without saving. Clear saved scenarios at any time. For information you email to the operator, request access or deletion using the contact address, subject to applicable obligations: kimst3676@gmail.com

Children

This service is intended for adult sellers and does not knowingly request children’s personal information.
