PiggyPrivacy Policy
Last updated: August 16, 2026
Calculator inputs. All calculations run locally in your browser. The numbers you enter are never transmitted to, or stored on, our servers.
Calendar reminders. The deadline and quarterly-calculator pages provide calendar downloads without email signup. Downloading a reminder does not submit an email address or calculator results to PiggyMath. A personalized calendar file includes the estimate shown on screen; if you import that file, your calendar app or provider may store it. You choose whether to import it. Automated email reminders are not currently offered. If you previously contacted us about reminders, you can ask about or withdraw that request by emailing contact@piggymath.com.
Partner embeds. The optional iframe widgets under /embed/ (for example the self-employment tax shell) inherit the same browser-only math: there is no calculator API, and the widget HTML itself does not load Google Analytics or AdSense. Sites that embed our widgets may still run their own scripts on the parent page outside the iframe.
Advertising & affiliate links. This site uses Google AdSense to display advertisements. Some calculator result screens may also show optional links to third-party freelancer tools (for example bookkeeping or banking products). If we enroll in an affiliate program for a listed product, we may earn a commission when you click through and buy; calculator inputs are still not shared with those partners. See the affiliate disclosure. Google and its partners may use cookies (including the DoubleClick cookie) to serve ads based on your prior visits to this or other websites. You may opt out of personalized advertising by visiting Google Ads Settings.
Analytics. This site uses Google Analytics 4 to measure aggregate traffic — pages viewed, approximate country, device type and how visitors arrived. Google Analytics sets cookies and processes this data on our behalf; it does not receive anything you type into a calculator, since those values never leave your browser. You can opt out across all sites using the Google Analytics Opt-out Browser Add-on, or block analytics cookies in your browser settings.
How PiggyMath compares on privacy
Many tax calculators ask you to create an account before showing results. PiggyMath’s estimates run in the browser first.
| Approach | Signup required? | Where do your profit numbers go? | Typical goal |
|---|---|---|---|
| PiggyMath | No | Stay in your browser (not sent to our servers) | Plan & set aside — we don’t e-file |
| Account-first tax apps | Usually yes | Often stored in their cloud to sync / file / advise | Filing, bookkeeping, or paid advice |
| Generic “free calculator” lead forms | Email wall common | May be used for sales follow-up | Lead generation |
Optional email reminders (when enabled) collect only your address for deadline notices — not the dollar amounts from the calculator. See the quarterly reminder section above.
