Privacy Policyسياسة الخصوصية
Last updated: July 2026
CalculatorLA.com ("we", "us", "this site") provides free online calculators for health, math, and everyday planning. This policy explains, plainly, what happens to the information you enter and to your general browsing data.
The numbers you enter into a calculator
Every calculator on this site — BMI, calories, body fat, dates, work hours, and so on — runs entirely inside your own browser using JavaScript. The values you type (weight, height, age, dates, or anything else) are processed locally on your device and are never transmitted to our servers, never written to a database, and never seen by anyone but you. Closing or refreshing the page clears them completely. We have no technical means of collecting or viewing what you type into a calculator, because that data simply never leaves your browser.
Cookies
This site uses a small amount of local browser storage (not tracking cookies) to remember two preferences: your chosen theme (light or dark) and your chosen language (English or Arabic). Nothing else is stored. You can clear this at any time through your browser's settings; the site will simply fall back to its default English, light-mode view.
Advertising and third-party tracking
CalculatorLA.com does not currently run third-party advertising or analytics scripts that track you across other websites. If that ever changes, this policy will be updated in advance to explain exactly what's added and how to opt out.
Server logs
Like virtually any website, the server that delivers these pages may keep standard technical logs (such as page requests and approximate error rates) for security and reliability purposes. These logs are not linked to the numbers you enter into any calculator, which — again — never reach the server at all.
Children's privacy
This site does not knowingly collect personal information from anyone, including children, because it does not collect calculator input from anyone in the first place.
Changes to this policy
If this policy changes, the "Last updated" date above will change with it. Continuing to use the site after an update means you accept the revised policy.
