Who we are
CarAllIn is a free, educational car-ownership calculator at carallin.app. You can reach us at hello@carallin.com.
What the calculator does with your numbers
The price, down payment, APR, miles, and other amounts you enter are processed by code that runs in your browser. We do not ask you to create an account, and we do not send or store your car scenarios on our servers. If you close or reload the page, your entries are gone.
Information collected automatically
Like most websites, the services that deliver this site receive standard technical information when you visit, such as your IP address, browser type, device type, the page you requested, the referring page, and the time of the request. This is used to deliver pages, keep the site secure, and prevent abuse.
Service providers
- Hosting and content delivery: The site is delivered through Cloudflare, which processes technical request data to serve and protect the site.
- Web fonts: Pages load fonts from Google Fonts. When your browser requests those fonts, Google receives your IP address and browser information. See policies.google.com/privacy.
- Advertising: Google AdSense (see below).
- Analytics: We use Google Analytics to understand traffic, such as how many people visit and which pages they read. Google receives the same kind of technical information described above. We use it only in aggregate to improve the site. See Google's privacy policy.
Advertising and cookies
Google AdSense is currently the only ad network we use. Through AdSense, Google and Google-certified third-party ad vendors may use cookies or similar identifiers to serve and measure ads, including ads based on your prior visits to this website or other websites. Visitors in the EEA, the UK and Switzerland are shown Google's consent message, which lets them choose how their data is used for ads. You can opt out of personalized advertising from Google by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at https://www.aboutads.info/choices.

If you email us, we keep the message long enough to reply. We do not add you to a marketing list.
