The short version: your calculator inputs never leave your browser. This page explains the details, including how analytics and ads work when they are enabled.
Last updated: October 8, 2026
Every calculator on upgrade.tools runs entirely in your browser. The numbers you enter — order frequency, average spending, delivery fees — are processed on your device to produce your results. They are never sent to our servers, never stored in a database, and never shared with anyone.
There are no accounts and no sign-ups. We cannot associate calculator results with you, because we never receive them.
The numbers you enter are never stored — once you close or reload a calculator, they are gone. This site itself keeps only two things in your browser, both stored on your device and never transmitted to us or anyone else: a local preference that snoozes the “install app” prompt if you dismiss it, and, if your browser supports it, an offline cache.
The offline cache is managed by a service worker to make the site faster and available without a connection. It stores the app shell, the pages you visit, and images — never anything you type into a calculator. You can remove it at any time by clearing upgrade.tools from your browser's site data.
When analytics is enabled, this site uses Google Analytics to understand aggregate usage — which pages are visited and whether a technical error occurred (for example, if a calculation fails, an error event is reported so it can be fixed). Cloudflare Web Analytics may also be used for privacy-safe, cookieless traffic measurement.
These services receive standard technical data such as your IP address, browser type, and the pages you visit. We do not use analytics to build advertising profiles and have no way to identify individual visitors from the aggregate reports we see.

Some pages may display ads served by Google AdSense, which keeps upgrade.tools free. When ads are shown, Google and its partners may use cookies or device identifiers to serve and measure ads. Depending on your region and settings, these may include personalized ads based on your browsing across sites.
You can control ad personalization in your Google Ads Settings, and your browser or device settings may also let you block or delete advertising cookies. Third-party vendors and ad networks may serve ads on this site subject to Google's partner-site policies.
upgrade.tools does not currently offer a way to save or share a calculation through a link. If we add a feature like that in the future, anything included in a shared URL will be visible in the link itself, and this policy will be updated before it ships.
If you have a question about this policy, email feedback@upgrade.tools or use the contact page.
This policy describes upgrade.tools only. External sites linked from these pages, including advertised services, have their own privacy policies.
