Privacy at HeyDéjàVu
Effective September 25, 2026
HeyDéjàVu is designed around mutual memories, not people search. We use information you provide to operate your private moments, compare independently submitted memories, enable mutual consent, deliver notifications you request, and operate private conversations.
What we process
This can include your account email, the approximate date and time of a moment, the place label and context you provide, your description of the shared scene, your connection category, consent choices, conversation messages, safety actions, and technical information needed for notifications and service security.
How matching works
HeyDéjàVu compares independently submitted memories using time, context, place wording and semantic similarity. A possible match does not reveal the other person’s identity or what they wrote. A private conversation opens only after both people independently choose to say Hey.
Sharing
When you choose to share a moment, HeyDéjàVu can create a share link or visual card. The public share experience is intentionally limited and is not designed to expose your identity, exact location, or private description.
Notifications
If you enable notifications, we store the technical push subscription needed to deliver them. Notification text is intentionally generic so private message content or identity is not exposed on a lock screen.
Safety and age
HeyDéjàVu is for adults 18 and older. It must not be used to track, identify, harass, or locate another person. Blocking and reporting controls may be used to protect participants and the service.
Retention and control
Moments and conversations are retained as needed to provide the service and enforce safety. Some expired or obsolete service data is cleaned automatically. Where the product provides deletion controls, deletion may be limited while an active mutual connection exists so one participant cannot silently disrupt the other participant’s active experience.
