Calculator entries

Calculations run in your browser. Your calculator labels, prices, quantities and spending limit are not submitted to this website or saved in browser storage. They remain in the open page until you clear or reload it. Public calculator use needs no account.

Catalogue search and product images

Search keywords and filters are sent to this website to search its stored catalogue. They are not sent to a language model. Shopee product images load from Shopee image servers, which receive ordinary image requests including your IP address. Offer data is refreshed server-side through the Shopee affiliate API.

Storage and website access

Unit-view preferences and signed-in saved product lists may be stored in your browser. Clearing site storage removes them. WordPress administration uses necessary sign-in cookies. Hosting infrastructure may process your IP address, requested URL, browser information and access time to serve and protect the website; these requests do not contain calculator entries.

No analytics or advertising network is enabled. Affiliate purchase links lead to Shopee, whose privacy practices apply there.
