For support, partnership, advertising, or feedback — email us directly:
We typically reply within 1-2 business days. Please include the tool or guide name you are asking about.
What we can help with
Bug reports and calculation errors: tell us the tool, the inputs you used, and the result you expected. If a number looks wrong, we will re-derive it from the published method and correct the page if needed.
Content corrections: if a guide cites an outdated price, a changed platform policy, or a claim you believe is inaccurate, send the section heading and the source you are relying on. Corrections are noted on the page once verified.
Privacy requests: questions about browser storage, advertising cookies, or consent choices can be sent to the same address and are handled as described in our Privacy Policy.
Partnerships and advertising: we review sponsorships case by case and decline anything that would require us to endorse an income claim. Editorial pages are never written by advertisers.
What we do not do
We do not offer individual financial, legal or tax advice, we do not review business plans, and we do not sell courses. If you need advice for a specific situation, consult a licensed professional in your country.
We never ask for passwords, card details, or personal data by email. Beware of impersonators.
