Who we are

ShackWiki (https://shackwiki.com) is run by Mick, 2E0CPU. You can contact us at contact@shackwiki.com.

The calculators

All calculations run in your browser. The numbers you enter are not sent to us or stored. If you use "Use my location", your browser asks permission first, and your position is used only on your device to work out your grid square.

The Morse code decoder processes audio files and microphone sound entirely in your browser. Nothing is recorded, uploaded or kept.

We save two settings in your browser's local storage: whether you chose light or dark mode, and the locator you last entered on the grey line map. They never leave your device.

Advertising

This site doesn't show adverts at the moment. If that changes, this page will be updated first to explain the cookies involved and how to opt out.

Your rights

Under UK GDPR you can ask what personal data we hold about you and ask us to delete it. As we don't collect personal data directly, this will usually concern data held by the services above. Contact us at contact@shackwiki.com, or complain to the Information Commissioner's Office (ico.org.uk).
