The Short Version
AllCalc's calculator features are designed to calculate in your browser without sending the numbers you enter to an AllCalc calculation server. Separate services do process some information: the site is delivered through Cloudflare, Google AdSense advertising code is included in page source, and messages sent through the Contact page are processed by FormSubmit. The sections below explain those differences.
Calculator Inputs and Local Preferences
The calculators use the values you enter to calculate results in your browser. Their calculation logic does not intentionally submit those values to an AllCalc server. AllCalc does not require an account or maintain an AllCalc account profile for calculator use.
To personalize the homepage's Featured Calculators section, the browser stores counts of calculator-card interactions in local storage on your device. This count is used by the page to choose featured items; it is not sent to AllCalc by that feature. You can remove it by clearing this site's data in your browser settings.
Contact Form Messages
If you send a message through the Contact page, the name, email address, and message you submit are sent to FormSubmit, an independent third-party form service, which processes the submission and forwards it by email. FormSubmit states in its documentation that it retains submission records for 30 days. An email copy may remain in the recipient's mailbox after that period, depending on that mailbox's retention and deletion practices. For more information, read the FormSubmit privacy policy. Please do not include passwords, payment information, or other sensitive information in a message.
Hosting and Technical Information
The site is hosted and delivered through Cloudflare. Like most hosting, content-delivery, and security services, the provider may process technical request information to deliver pages, maintain service reliability, and detect abuse. See Cloudflare's privacy policy for details of its practices.
Advertising, Cookies, and Third-Party Services
AllCalc includes Google AdSense advertising code. When that code makes requests, Google and its advertising partners may receive or process information such as your IP address, browser or device information, cookie or other identifier data, the page being visited, and ad-related interactions. Google and its partners may use cookies, web beacons, IP addresses, or similar technologies to serve, measure, and protect advertising. Third-party vendors, including Google, may use cookies to serve ads based on a user's prior visits to AllCalc or other websites. Whether an ad is displayed, and which advertising features are used, can vary by page, visitor, and configuration.
You can learn about Google's advertising technologies and how Google uses information on partner sites. You can manage personalized advertising in Google Ads Settings or use the industry opt-out page at aboutads.info. Browser settings can also control some cookies and local site data. These options may not stop every form of technical processing by a service.
Where a visitor's location or applicable law requires a consent choice for certain advertising technologies, that choice must be handled separately; this policy page is a disclosure and is not itself a consent mechanism.
Security and Changes
The site is served over HTTPS, which encrypts the connection between your browser and the site. No online service can promise that every system or transmission is risk-free. This policy may be updated as the site or its providers change; the date at the top will be revised when the policy is materially updated.
