Report a reproducible calculation issue.

Email yardfill.helpful594@aleeas.com for questions about Pathsphere. This is the owner’s existing shared public forwarding alias for the free-tool collection. No new mailbox or private destination is published.

What helps

Include the two latitude/longitude pairs, radius, browser name and a short explanation of the result you expected. Plain decimal inputs are enough to reproduce a calculation; screenshots are optional. If the question concerns a pole, longitude alias or antipodal pair, the method notes may explain the convention.

Protect sensitive information

You do not need to send your location, address or travel plans. Use made-up coordinates that reproduce the issue when possible. The calculator itself does not email your inputs, access your device location or send a support request. Opening the email link is your own choice and uses your email application.

Scope of help

Pathsphere is a free mathematical utility. It cannot validate a survey, produce a reliable road or flight route, choose a coordinate datum or provide navigation instructions. Its calculations describe an ideal sphere with the radius you enter. Read the privacy page for local inputs, optional exports, hosting and current measurement disclosures.
