Privacy or data requests
KalkWise does not collect personal data. All calculations run locally in your browser. See our Privacy Policy for full details.
What happens after you report an error
- 1. Reproduction. We re-run your exact inputs against the calculator and against the underlying formula by hand.
- 2. Source check. If the discrepancy involves a tax rate, bracket, or limit, we verify the figure against the official source listed on our data sources page (IRS, SSA, BLS, state revenue departments).
- 3. Fix and regression test. Confirmed errors are corrected and a permanent test case with your scenario is added to our automated math suite, so the same mistake cannot silently return.
- 4. Public record. Material corrections are noted on the affected page's methodology section per our editorial policy.
What we can't help with
KalkWise publishes educational tools, not advice. We cannot review your personal financial situation, recommend specific investments, loans, or insurance products, prepare your tax return, or tell you what decision to make. For personal guidance, consult a licensed professional — a CPA or enrolled agent for tax questions, a fee-only fiduciary advisor for investment decisions, or a HUD-approved counselor for housing questions. If you ask us for personal advice by email, we'll point you to the relevant calculator and these same referral options.
