Privacy Policy

MultiConvers does not require an account. Values you type into calculators, text tools, utilities and the QR generator stay in your browser. That includes generated passwords, JSON, Base64 or URL input, hashes and encoded text. Calculations, hashing and QR generation run locally. We do not send those values to our servers as first-party form submissions or analytics events, and we do not use them to build advertising audiences.

If you add a tool to Favorites, we store its name and page slug in your browser (localStorage) so the list is there the next time you visit on that same browser and device. The list never leaves your device, is not sent to our servers, and is not used for advertising or analytics. No account is required.

You can remove individual tools or choose Clear all favorites in the Favorites menu. You can also delete this site's stored data in your browser settings. Favorites are not part of the ads or analytics consent message; they only exist because you saved a tool.

If you use the contact form, we receive the name, email address, subject and message you submit. That information is sent to us by email through our email provider (Resend) so we can reply. We keep messages only as long as needed to handle your request. Honeypot fields used to block spam are not read as real submissions.

Production pages may load Google AdSense Auto ads. Google and other third parties may place and read cookies on your browser, or use web beacons, pixels and your IP address to collect information as a result of ads being served on this site. That can include serving personalized or contextual ads, measuring ad performance, frequency capping, and detecting fraud or abuse.

We do not pass calculator input or contact-form contents to Google for advertising. AdSense may still use the page you visit (such as the URL and general page context) when selecting ads.

To see how Google uses data when you visit sites that use its services, read How Google uses information from sites or apps that use our services. Google also explains how advertising cookies work and publishes its Privacy Policy.

Live deployments may load Vercel Analytics and Google Analytics 4. They record page views (for example which pages are visited), basic device and browser information, and approximate location derived from IP address. Google Analytics may use cookies or similar technologies. Neither receives the numbers or text you type into a tool.

Google explains how it uses data from sites that use its services in How Google uses information from sites or apps that use our services and in its Privacy Policy.

Visitors in the European Economic Area, the United Kingdom and Switzerland see a consent message (Google Funding Choices) before cookies or similar technologies are used for ads or analytics. You can accept, reject or manage purposes there. You can change that choice later from the privacy options control that Google adds to the page.

Visitors in applicable U.S. states may see a separate privacy message with options to opt out of the sale or sharing of personal information for cross-context advertising.

You can also opt out of personalized advertising at Google Ads Settings.
