End User License Agreement

This End User License Agreement (the "Agreement") governs your installation and use of the BesiaBIM software — including our host add-ins (for Revit, AutoCAD, DraftSight, Inventor, and similar applications) and any standalone desktop or web tools (collectively, the "Software"). The Software is provided by Sebastian Maciuszko trading as SeboticAI (ABN 76 842 369 494) of South Australia ("we", "us", "BesiaBIM").

By installing, activating, signing in to, or using the Software, you ("you", the "Licensee") agree to this Agreement. If you are accepting on behalf of a company, you confirm you have authority to bind that company. This Agreement is in addition to our Terms of Service and Privacy Policy. If this Agreement and the Terms of Service conflict on a question of software licensing, this Agreement controls; the Terms of Service control on commercial and account matters.

1. Licence grant

Subject to an active, paid (or trialling) subscription and your ongoing compliance with this Agreement, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and use the Software for its intended purpose within your own business. The Software is licensed, not sold. We and our licensors retain all right, title, and interest in and to the Software.

2. Licence and device limit

Each subscription is licensed to a single user. That user may activate the Software on up to two (2) devices concurrently per licence. Activating a further device requires deactivating an existing one (sign out on the old device, or contact support). Licences are tied to the purchasing user and may not be shared across individuals, companies, or with contractors who are not operating directly on your behalf. We may offer team plans with multiple seats in future; until then, one subscription means one user.

3. Activation, sign-in, and offline use

Activation is performed by signing in through your BesiaBIM account. On activation, the Software stores a short-lived, cryptographically signed licence token (valid for up to 7 days) on the device, bound to that device. The Software verifies this token offline so it keeps working without a constant connection. To respect intermittent connectivity, an expired token continues to function during a short offline grace period before the Software requires you to reconnect and renew.

The Software periodically re-checks your entitlements with our servers. If a licence is no longer valid (see §6), the Software will stop authorising the affected product on next launch.

4. Restrictions

You must not, and must not permit any third party to:

• reverse-engineer, decompile, disassemble, or otherwise attempt to derive the source code of the Software, except to the limited extent that law expressly permits despite this restriction;
• copy, resell, rent, lease, sublicense, redistribute, or otherwise make the Software available to any third party;
• circumvent, disable, or tamper with the licensing, activation, device-limit, or update mechanisms;
• remove, alter, or obscure any branding, version, copyright, or proprietary notices; or
• use the Software to build a competing product or in any unlawful manner.

5. Updates

We may provide updates, patches, or new versions of the Software. Updates are covered by this Agreement unless they ship with separate terms. We may discontinue a product with reasonable notice to active subscribers; your statutory rights are unaffected.

8. Data the Software handles

To enforce licensing, the Software sends only what is necessary over an encrypted connection: your signed-in session, your entitlements request, and a one-way device fingerprint (a hash derived from stable machine and account identifiers) plus a minimal device descriptor (the operating system version and the host application version, e.g. "Revit 2026") so you can recognise the device you are authorising. We do not collect your computer's name (hostname) or other personally identifying device detail, and we do not collect drawing contents, models, or project data through the licensing mechanism. See our Privacy Policy for details.

9. Your responsibilities

The Software is a productivity tool, not a quality-assurance tool. You remain responsible for visually checking every output (drawing, sheet, model change, exported file) before any production, construction, fabrication, or downstream use. You are also responsible for holding a valid host-application licence (e.g. Revit, AutoCAD, DraftSight, Inventor) at the tier required to run the add-in on each workstation. We do not supply third-party host licences.

10. Warranty disclaimer

The Software is provided "as is" and "as available" without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement, to the maximum extent permitted by law. Nothing in this Agreement excludes, restricts, or modifies any consumer guarantee under the Australian Consumer Law that cannot lawfully be excluded.

11. Limitation of liability

To the maximum extent permitted by law, our total aggregate liability under or in connection with this Agreement is limited to the amount you paid us for the Software in the 12 months immediately preceding the event giving rise to the claim. We are not liable for indirect, incidental, special, or consequential losses (including lost profits, lost data, rework, material waste, or business interruption), regardless of cause. Nothing here limits rights under the Australian Consumer Law that cannot lawfully be excluded.

12. Changes and governing law

We may update this Agreement; we will notify active subscribers by email at least 14 days before material changes take effect, and continued use after that date constitutes acceptance. This Agreement is governed by the laws of South Australia, and both parties agree to attempt to resolve any dispute through good-faith discussion before any formal action.
