Purchase, installation and activation

Use this page for desktop commercial support. Do not send passwords, passkeys, full card details or confidential audit content.

Payment completed, access pending

Keep the Stripe receipt and sign in with the same verified business email used during purchase. Access is created only after server-side payment verification.

Wrong email used

Contact support before attempting another purchase. Include the business name, purchase date and Stripe receipt reference only.

No available device licence

Each purchased Windows or macOS device licence may be linked to one active installation at a time. Buy an additional licence for an additional device, or use the controlled replacement process when an old device has been replaced, lost, stolen or is no longer usable.

Old device after replacement

The replaced installation enters read-only recovery mode. Existing audits remain available for viewing and export. Creating, importing or modifying audits requires an active device licence.
