Privacy & directory

What we collect

• Required for membership: name, email, country.
• Required to post physical materials: postal address (ID card and certificate).
• Optional: city, existing callsign/handle, experience level, message to HQ, directory visibility preference.

A home address is only needed so HQ can post your membership card and certificate. It is not required for using a DT callsign on the air or for on-air nets.

Who can see what

• HQ only: full name, email, postal address, payment notes. These are not published on the public website.
• Members’ directory (logged-in members): only the fields you choose under “Directory visibility” (default: callsign + country). Full street address is never shown in the directory.
• Public sample listing: may show callsign and first name or handle only, if you allow listing.

How long we keep data

Membership records are kept for as long as your membership is active (lifetime by default) so HQ can reissue materials and manage unit numbers. Contact-form messages are kept only as long as needed to reply.

Corrections and removal

Email HQ via the contact page to:

• Update your address, email, or directory preferences
• Request removal from the interactive directory
• Request deletion of your membership record (this may retire your unit number from reassignment for a period set by HQ)

On-air nets and group activities

Participating in an on-air net does not require your postal address. For membership data, see the privacy and directory sections above.
