How to Choose an Emergency Contact — What to Decide Before Heartbeat Detection

The emergency contact is the most important human checkpoint in heartbeat detection. The system can detect a long-lapsed check-in, but a contact is better placed to tell whether you are traveling, hospitalized, truly unreachable, or simply forgot to log in.

Four dimensions for choosing a contact

• Trust — Does the person respect your privacy and handle information as agreed
• Responsiveness — Do they check email, SMS, or WeChat regularly and can they reach you promptly
• Relationship stability — Is the relationship stable long-term and suited to handling sensitive information
• Handling ability — Can they contact family, understand account handover, and grasp basic security risks

Who is not a good fit

Avoid friends you have lost touch with, people in unstable relationships, those who do not use email or SMS, or anyone who might misuse the information. Being a contact is not an honorary title — it is a role that demands a real response.

Why advance confirmation matters

Contact confirmation must be actively agreed by the contact, not just an email address typed into a system. TimeWill's confirmation links use a GET read-only, POST to confirm design to reduce the risk of email scanners confirming by mistake.

How many contacts to set

Most users should set at least one; people living alone, in high-risk jobs, or who travel often should set 2–3. Different contacts can take on different roles: one verifies your status, one reaches out to family, and one receives specific instructions.

How to reduce false triggers

• Set a reasonable grace period — Leave buffer for travel, network outages, hospital stays, and forgotten check-ins
• Notify yourself first — The T1 stage reminds you first, without releasing sensitive content
• Contact confirms next — The T2 stage has the contact verify your status before the flow continues
