Cookies and browser storage

Cookie and Browser Storage Policy

Cookies, browser storage, and server-side data are different mechanisms. This page describes their current use separately.

Cookies

CindrenCalc sets no application cookies of its own. When advertising is active, Google AdSense and Google CMP may use cookies or device storage in line with the choice communicated through the CMP. CindrenCalc analytics cookies remain disabled.

localStorage

Cindren Forge, calculation history, and selected tools may store projects, preferences, or workspace state locally. Data are not automatically sent to the server merely because they are in localStorage.

sessionStorage

Calculation history may use sessionStorage as a temporary fallback when persistent storage is unavailable. Its content normally disappears after the tab or browser session ends.

Advertising and Google CMP

Google Privacy & messaging manages consent and preferences for Google AdSense. The CMP/TCF signal, not a CindrenCalc interpretation, controls the permitted advertising processing. The current providers and purposes are presented in the CMP message.

PayPal link

The support page contains an ordinary external link. CindrenCalc embeds no PayPal script, SDK, iframe, or tracking element and initiates no payment cookies or other PayPal resources before you select the link. PayPal's rules apply after you leave CindrenCalc.

Changing settings

Privacy settings in the footer reopen Google's official message so the user can change a choice. CindrenCalc creates no consent identifier, consent history or manual preference database of its own.
