Sharing contact details is easy. Keeping them accurate, reaching the right person, and deciding what others may do with them is harder. An email address shared for one conversation can remain in an address book long after a role changes or the original reason for contact has ended.
A public profile has a wider audience
A public profile can help people find you. The same visibility can also make your details available to people you did not intend to contact, including automated collection tools. Decide which details belong on a public page and which should be shared only with selected recipients.
The National Cyber Security Centre recommends reviewing who can see your information ā and which details they actually need. Public information can also make impersonation and phishing messages more convincing.
A QR code is a shortcut, not a privacy setting
A QR code may contain contact information directly or open a profile on a website. The privacy consequences depend on the information and the access controls behind it. A public link and a profile restricted to selected recipients are different arrangements, even if both use a QR code.
Before opening an unfamiliar QR link, inspect its destination. The Federal Trade Commission explains how substituted QR codes can lead to fraudulent websites ā. This is a risk of deceptive destinations, not evidence that every QR code is unsafe.
Updated profiles do not update every copy
A live profile can be edited when a job title, email address, or responsibility changes. An exported contact file or forwarded message may still contain the old details. Withdrawing future access to a profile does not automatically remove information that someone has already downloaded or copied.
Different roles need different boundaries
You may represent yourself, a team, or an organization in different conversations. A work contact does not automatically need your private phone number. A colleague taking over a project needs the relevant business context, not unrestricted access to your personal contacts. Clear roles help define what should be shared and who may change it.
Verification answers a specific question
Verification may confirm control of an email address or evidence of an organizational affiliation. The meaning depends on what was checked and when. A verified label does not guarantee that every profile detail is current or that every future message is trustworthy.
Questions to ask before sharing
- Which details does this recipient need for this purpose?
- Will the information remain in this service or be copied elsewhere?
- How will corrections and role changes reach existing contacts?
- Can I stop future access or unwanted communication?
How YARD Cards relate to these questions
YARD Cards are being developed as connection profiles with context-specific sharing and communication preferences. The aim is to let people use existing services while deciding which information is available to whom. Those controls are a product direction, not a claim that every feature is available today or that information can never be copied.
The comparison of free and premium YARD Cards explains the planned distinction between a basic profile and additional management tools.
