Contact
I read every message.
If you have spotted a calculation error, found a broken link, or noticed something I could explain more clearly, I would like to hear about it. The best way to reach me is by email:
I usually reply within 2–4 business days. Because I work at sea, replies can occasionally take a little longer during a long voyage.
Reporting a calculation error or bug
Please include:
- The address (URL) of the page, for example calcsnap.app/finance/mortgage-calculator/
- The values you entered
- The result you got and what you expected
- Your browser and device, for example "Chrome on Android" or "Safari on iPhone"
- A screenshot, if you can
Writing "possible calculation error" in the subject line helps me find it quickly. Errors in calculations are always fixed first.
Suggesting a new tool or game
Suggestions are welcome, especially in Finnish and Swedish, where good free tools are harder to find. I am most likely to build tools that do one clear job, run entirely in the browser without a server, and are useful to many people.
Advertising and business enquiries
CalcSnap shows ads through Google AdSense only. I do not sell sponsored posts, paid links or direct ad placements.
