Blackstar support

Account access

Blackstar uses your phone number and a verification code to sign in. If a code does not arrive or you cannot access your account, contact team@blackstar.inc. Never share a verification code with support.

Voice and microphone

Tap Talk to begin a voice message, then swipe up to send. You can also hold Talk and swipe upward with the same finger. Use Type if you prefer text.

With microphone permission, Blackstar keeps its microphone ready while you are signed in and the app is open in the foreground. Training mode includes nearby audio outside Talk; Private keeps outside-Talk readiness audio on your device and discards it. Leaving the app stops new microphone capture, though uploads of audio already captured may finish afterward.

If voice is unavailable, check microphone access in iOS Settings → Privacy & Security → Microphone → Blackstar. You can also revoke access there.

Files and uploads

Wait for your attachments to finish uploading before sending. If an upload fails, check your connection, then retry the failed attachment or remove it from the draft. If the problem continues, contact us with the file type, approximate size, and error message; you do not need to include the file itself.

Training and Private

Open Account → Training & Private to view or change your mode. Stop audio training switches to Private and stops new training collection. It removes unattended clips and excludes audio from future training exports, but cannot undo training already completed.

Audio captured outside Talk is used only to train and evaluate Blackstar’s end-of-turn model and is retained for up to 30 days. Submitted voice messages follow chat-history retention. Private messages you send still go to Blackstar and its processing providers so the service can answer you. See the Privacy Policy for details.

Connections and permissions

Open Account → Connections to manage linked services. Account → Notifications opens notification settings. Location permission can be changed through Account → Location or iOS Settings. Optional connected services may require their own account and permissions.

Subscription help

If Manage subscription is shown in Account → Training & Private, use it to manage your current plan. Removing the app or signing out does not cancel a subscription. Contact team@blackstar.inc for billing help. Availability, price, and payment terms are shown before purchase.

Delete your account

In Blackstar, open Account → Advanced → Delete account, then confirm Delete everything. This removes your Blackstar account and signs you out. Wipe chat and memory is a separate action and does not delete your account.

If you cannot sign in, email team@blackstar.inc for help with account or data deletion. Some records may remain where permitted or required by law, as explained in the Privacy Policy.
