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.
Quarterly deadline reminders. On deadline and quarterly-calculator pages you may optionally submit an email address for estimated-tax date reminders. We intend to send only: (1) a double opt-in confirmation, (2) reminders for the four federal estimated-tax due dates each year, and (3) rare tax-year constant updates. We do not upload your profit figures or calculator results with that signup — those stay in your browser; if you download a personalized calendar file, any dollar amount in that file lives only on your device. Until an email provider is connected, submitting the form still downloads a calendar alert and may open a mailto draft to contact@piggymath.com so we can confirm manually. You can ask to be removed at any time 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.
