Your calculations stay practical and data collection stays optional

Calculator arithmetic is generally performed in the browser and does not require an account. Do not enter names, account numbers, tax IDs, medical details, or other sensitive personal information into free-text fields or messages.

New calculator share links place the scenario after the URL's # fragment so it is not included in normal HTTP requests or referral headers. Older query-string links remain compatible; after their recognized calculator values are restored, those values are removed from the address bar while unrelated query parameters are preserved. Legacy requests may already have appeared in hosting or security logs. Anyone who receives the complete URL, and software that can read browser history or extensions, can still see fragment values. Review every URL before sharing it.

Local browser storage is used sparingly. The site remembers whether you have turned analytics off, and the mutual fund calculator keeps its most recent inputs so the form survives a reload. Those values stay on that browser unless a feature says otherwise, and you can remove them through your browser's site-data settings.

When a Google Analytics measurement ID is configured, analytics loads by default, and we may receive page paths, device/browser information, approximate location, referrer information, and interaction events such as opening or sharing a calculator. Analytics page locations and referrers are stripped of query strings and fragments before they are sent, so the figures a calculator carries in a share link never reach analytics, and calculator field values are not included in analytics events. Google Signals and ad personalization are turned off for this property.

You can turn analytics off for this browser at any time using the button below. That choice is stored locally and applies until you clear the site's browser data. Essential storage used for your settings is unaffected either way.

Links to regulators and other third parties open websites with their own privacy practices. Hosting and security providers may process routine request information such as IP address, user agent, timestamps, and URLs for delivery, abuse prevention, and operational logs.

Retention for those provider logs and any consented analytics is governed by the configured provider settings. We keep only what is reasonably needed to operate, secure, and improve the service.
