Security at Backline

Backline is a cloud-hosted platform. Vercel hosts the web application and its web-server routes. Convex provides the application backend, realtime database, server functions, and primary product-data storage for guest lists, table data, advancing records, incidents, and audit trails.

Persistent uploaded files use Cloudflare R2 object storage. Backline does not operate the underlying hosting, database, or object-storage infrastructure itself.

Every connection to the Backline web app and APIs is protected with HTTPS/TLS. Operational data, auth tokens, and device sync traffic are encrypted in transit before they leave the browser, tablet, or mobile device.

Structured product data uses provider-managed Convex storage, and persistent files use Cloudflare R2. Payment details are entered on provider-hosted checkout surfaces operated by Polar or Stripe; Backline stores only the identifiers and status needed to run subscription and reservation-deposit workflows.

Backline uses WorkOS AuthKit for authentication, session management, and MFA. Multi-factor authentication is optional.

Role-based permissions limit what each teammate can access. Admins can remove a teammate at any time.

Removing a teammate blocks their future access. A phone they used keeps tonight’s door list until it signs out. Signing out of the mobile app deletes the event data stored on the phone. Customers share responsibility for the physical security of phones and tablets and for removing departing staff quickly. Audit logs preserve the history of operational changes for review.

Polar processes subscription checkout, billing, invoices, and receipts. Stripe processes table-service reservation deposits. Backline retains provider identifiers and payment or subscription status needed to manage those workflows.

Backline uses PostHog for product analytics, feature flags, experiments, session replay, and application logs. Sentry provides error monitoring, diagnostics, and user feedback tooling. Access to these systems is limited to staff who need it for product quality, security, and reliability work.

Resend delivers Backline’s transactional and operational emails and receives inbound email used by supported import workflows.

Anthropic runs the AI models behind Eve, rider reading, and email import. Eve sees only what the signed-in user can see, and it changes something only after that user approves it.

Backline records operational activity, including check-ins and undo events. Our authentication provider records login events to help review access.

These logs help customers review activity and investigate issues. Venue admins can review logs inside the product, and we retain them for a reasonable period consistent with our Privacy Policy.

Code lives in version control with review required before deployment. Dependencies and frameworks are updated regularly, and we ship through an automated pipeline on Vercel. Production access is restricted to operators who need it, and secrets stay in managed secret stores or environment variables, not in source control.

Security is shared. Backline supplies role-based permissions and fast access removal. Customers are responsible for:

• Assigning appropriate roles to staff and limiting access to sensitive workflows.
• Keeping phones and tablets locked, and signing retired ones out of Backline.
• Removing user access immediately when staff leave or duties change.
• Maintaining physical security in venues, offices, and storage areas.
• Ensuring they have the rights to upload guest, artist, and operational data into Backline.

If you discover a vulnerability or notice suspicious activity, email security@getbackline.app with as much detail as possible. Please do not publicly disclose findings until we have investigated and addressed the issue. We respond quickly to legitimate reports affecting customer safety or data integrity.

Our security practices evolve alongside the platform. We will update this page when material changes occur and may notify customers in-app or via email if the changes affect how their data is protected.
