This policy explains how Calculator All-in-One handles basic website data, advertising, analytics, and contact messages.
Most calculator arithmetic is processed in your browser and is not submitted to Calculator All-in-One. No account is required for normal use. Do not enter confidential financial, medical, identity, authentication, or legal information into public online tools.
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.
The currency converter sends the selected base currency to open.er-api.com to request indicative rates. 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. Do not use the QR tool for passwords, payment credentials, private records, or authentication tokens.
Google Analytics is used to understand aggregate visits and page usage. Depending on browser settings, consent choices, and Google configuration, it may receive device and browser information, approximate location derived from IP address, page addresses, referring pages, and interaction events. We use this information to identify errors and improve navigation and content.
Google AdSense supports free access to the site. Google and its partners may use cookies, web beacons, IP address, device identifiers, and similar technologies to deliver, measure, limit, or personalize advertising where permitted. Ads are separate from calculator results and we never ask visitors to click them.
Your browser can block or delete cookies. Where required, a consent message should provide choices before optional advertising or analytics storage is used. You can review Google advertising controls at My Ad Center and Google\'s data explanation at How Google uses information from partner sites.
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 sites have their own policies. Analytics, advertising, exchange-rate, email, hosting, and payment providers determine their own retention periods. Calculator All-in-One does not maintain user accounts or a server-side history of ordinary calculator inputs.
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.
This policy is updated when data handling, providers, advertising, analytics, or calculator behavior changes. For privacy questions or deletion requests concerning information sent directly by email, contact support.aiagents@gmail.com and describe the relevant message.
