WEBSITE INFORMATION · OCTOBER 26, 2026

Here is how this Studio website handles calculator entries, optional analytics and purchase links.
Free calculator entries
The Craft Fair Stock Check and Reseller Profit Check calculate in your browser. Their code does not send product names, quantities, entered resale amounts or calculated results to our server, PostHog, Etsy or Gumroad. Entries are not saved between visits. Copy or download the result if you want to keep it. If you allow analytics, the calculator sends only usage events such as starting a check, checking a result or exporting a summary. Those events never include your product name, counts, entered amounts, calculated numbers or summary text.
Interactive teaching example
The returned-camera demonstration uses fictional records. Its optional return-postage adjustment runs in browser memory and is not stored or transmitted. If you allow analytics, it reports only that you intentionally started the demonstration or revealed its full-history result. It sends no entered postage, calculated amounts or record contents. Revealing the result does not prove reading, understanding or purchase.
Website requests
The site is hosted through Cloudflare Pages. Ordinary web requests can disclose technical information such as your IP address, browser information and requested page to the hosting provider. See Cloudflare’s privacy information.
Optional website analytics
PostHog loads only after you choose Allow analytics. It measures page and product-preview visits, calculator starts, explicit result checks, validation failures, exports, demonstration starts/result reveals and outbound shop clicks. Events include the page, product identifier, shop, campaign, creative and a pseudonymous browser/session identifier. Session replay, automatic form capture and advertising tracking are disabled. We request IP/geolocation suppression and do not identify you by name or email. We do not send calculator entries or unrestricted URL parameters.
Your analytics choice is saved in this browser’s local storage under studio_analytics_choice_v2. Essential only keeps PostHog unloaded. After consent, PostHog saves a pseudonymous browser identifier in local storage, and the site saves campaign attribution in session storage. Returning browser identifiers can be used to recognize repeat visits. You can change the choice using Analytics settings in the footer; withdrawing consent reloads the page to stop loading the tag. Withdrawing consent clears the saved campaign attribution and resets the analytics identifier before reload; it does not erase events already sent. See PostHog’s privacy information. Visitors who decline analytics, block scripts or use another device may be absent from these reports. A shop click is not proof of purchase; checkout happens in Etsy or Gumroad.
Marketplace purchases
Product links lead to Etsy or Gumroad. Their pages, payment collection, accounts and downloads follow their own policies. We do not collect payment details on this website. The seller may receive the purchase and contact information made available by the marketplace to fulfill and support an order.
Some links include campaign parameters so destination analytics can distinguish where a visit originated. They do not contain the calculator values. This website does not include an email signup or file-upload form.
