Calculator inputs
Most calculator arithmetic is processed locally in your browser memory. Calculator All-in-One does not maintain a server-side history of the personal numbers, financial amounts or measurements entered into ordinary calculators, or sell those inputs. No account is required for normal use. Some tools request external data as explained below; this policy does not imply that every operation stays on your device. Do not enter confidential financial, medical, identity or authentication information into public tools.
PDF converter files
The PDF Converter and related PDF tools read selected PDFs or images in your browser for conversion, merge, split, raster compression, password-planning notes, or OCR text extraction. Calculator All-in-One does not receive, upload, store, or keep a history of these files. The tools load public browser libraries for PDF rendering, PDF editing, ZIP packaging, PDF generation, and OCR, so avoid sensitive contracts, medical records, identity documents, bank statements, passwords, or permission-restricted files in any general online utility.
Inputs sent to third parties
The currency converter sends the selected base currency to open.er-api.com to request indicative rates. When a food name is not in the local database, the nutrition tool may send that name to USDA FoodData Central (api.nal.usda.gov) to look for a match. Do not include personal details in a food search. The QR generator formats and renders QR codes in your browser; Calculator All-in-One does not send the QR payload to a QR image provider. Wi-Fi QR codes contain the entered network password in readable form. Anyone with the QR image can recover it; use a guest network. UPI QR codes contain payment routing details, not your PIN or OTP. Never encode private account passwords, authentication tokens or records.
Google Analytics
As of 5 October 2026, this release does not load Google Analytics. Earlier versions used it to measure visits. Removing the loader stops new collection by this site; it does not delete information previously held by Google. We will update this policy and implement appropriate privacy choices before enabling optional analytics again.
Google AdSense
The Google AdSense connection script is installed for publisher ca-pub-9409281508068005. We may display advertisements served by Google and participating advertising partners; actual serving depends on site approval and account settings.
Third-party vendors, including Google, use cookies to serve advertisements based on prior visits to this website or other websites. Google advertising cookies enable Google and its partners to personalize ads based on those visits. Advertising cookies may be associated with doubleclick.net or Google domains. Other participating ad networks may also use cookies or similar technologies when their ads are served.
You can manage or opt out of Google personalized advertising through Google Ads Settings. You can also review participating third-party choices through the Digital Advertising Alliance consumer choice page. Opting out of personalization does not necessarily remove advertisements or all advertising cookies. See Google advertising privacy information for further details.
Cookies and privacy controls
Google AdSense connection code is installed. Google may process connection data and use cookies or similar technologies for advertising, depending on approval, account settings and applicable consent requirements. Google Analytics remains disabled. This site does not currently provide a consent banner. Local preferences are described below. Fonts, browser libraries, exchange-rate requests and hosting still involve third parties and may disclose connection data such as IP address. Your browser can clear stored site data. See how Google uses information from partner sites for Google's explanation of its services.
Contact messages
If you email us, we receive the address and content you choose to send. We use it to respond, reproduce a reported problem, consider a correction, and improve the site. Do not email passwords, financial-account details, government identifiers, medical records, or other sensitive data.
External links and retention
Hosting providers may record IP addresses, browser information, referring pages and request timestamps for security, delivery and fault diagnosis. We do not claim these logs are anonymized: their handling and retention depend on the provider. External websites, advertising providers and email services have their own privacy and retention policies.
We do not maintain user accounts or a server-side history of ordinary calculator inputs. Disabling an analytics loader does not erase historical data held by an analytics provider. Review the provider privacy notices when using external links or services.
Children and professional decisions
The site is a general-audience utility and is not intended to collect personal information from children. Health, finance, tax, legal, and engineering outputs are educational estimates; users should verify important decisions with qualified professionals and current official sources.
