The Blackbar macOS application has no network capability. Its binary ships without any network entitlement, and this is verified by an automated test on every build. Your screenshots, the text recognized in them, and everything you redact are processed entirely on your own Mac and are never transmitted anywhere. There is no analytics, no telemetry, and no crash reporting in the app — ever.
Your license is a small signed file you receive by email and drag into the app. Verifying it happens locally using public-key cryptography. The app makes no activation call and stores no identifier about your machine.
When you buy Blackbar on this website, payment is handled by Stripe, which collects your email and billing details to process the transaction and any applicable tax. We use your email address solely to send you your license file (delivered via Resend) and, if needed, to provide support. We do not sell or share your information, and we do not send marketing email unless you ask us to.
Through Stripe we can see the record of your purchase (email, amount, country for tax, purchase ID). We retain this as required for accounting and support. You can request deletion of your support correspondence at any time.
