What we will not do
- We will not add an email newsletter. You are not a list to grow.
- V1.0 shows no ads and no paid promotional links. If affiliate recommendations are added in the future, they will be clearly labeled as such.
- We will not give personal financial advice over email. The calculators are educational, full stop.
