Contact
Tools Harbor is built and maintained by Shilpa Xavier, a cyber security professional and security solution design expert. Email is the fastest way to reach us — there is no contact form to fill in and no ticket queue.
What to write about
- Suggest a tool. Tell us the task you are trying to do, not just the tool name — it helps us build the right thing.
- Report a bug. Include the tool, your browser, and the input that misbehaved. Every tool runs client-side, so we cannot see your data or reproduce it from logs.
- Question about a calculator. Happy to explain the formula any of the finance calculators use.
- Corrections. If something on a reference page is wrong or out of date, we want to know.
What we cannot help with
The finance calculators are educational tools, not advice. We cannot advise on your specific mortgage, retirement plan or tax situation — please speak to a qualified professional for that.
Privacy
Emailing us shares your address with us and nothing else. The tools themselves never send your input anywhere — see the privacy policy for detail.
