HACALL

Warm tone Drag to turn the hologram

Send voice hologram messages and make real-time audio calls with a live 3D hologram. No phone number or camera required.

Profile photo is optional

Every new account starts with a generated avatar. After creating your account, you can choose a profile photo from your profile page; it becomes the face of your 3D hologram.

Voice chats. No camera required.

Speak through the 3D hologram without appearing on camera. Voice calls and voice messages use your microphone; the app never requests camera access. Private chat text, voice-message captions, and audio are end-to-end encrypted. Clear, direct communication with privacy in mind.

HACALL Holo is for adults 18 and older only. Anyone under 18 may not use the app.

          Voice feature consent

          HACALL Holo will ask your browser for microphone access when you choose a voice feature.

          This consent does not replace your browser’s microphone permission.

          New chat

          Compare these codes with this person in person or on a call you trust. If they match, nobody is intercepting your messages.

          Your chat identity code

          Blocking prevents this user from messaging or calling you. Delete conversation hides this chat only from your account; they keep their copy.

          Recover your account

          Use the private recovery code created for your account to set a new encryption password. The public chat identity code is not a recovery code. Recovery works only if you saved a private code beforehand.

          After recovery, save the newly issued code. The old code will no longer work.

          Contact Support

          Send a message to HACALL support. Your reply email and message will be sent privately to the support team.

          Set up a private recovery code

          This is separate from the chat identity code. Save it somewhere private; anyone with it can reset your password and unlock your encrypted messages.

          Save your private recovery code

          This 24-digit code is shown once. Keep it offline and never share it. It can reset your encryption password and unlock your encrypted messages. It is not the chat identity verification code.

          Change password

          Your other devices will be signed out.

          Delete account

          This permanently deletes your profile, photos, conversations, podcast channel and episodes. Your username becomes available to others. Any commercial subscription will stop renewing at the end of its paid period. This cannot be undone.
