End User License Agreement

1. Agreement & acceptance#

This End User License Agreement (“Agreement”) is a binding contract between you (“you”) and Trelawny Enterprises LLC (d/b/a CAD Keeper) (“we,” “us,” “our”) for the CADKeeper desktop software, including its installer, updates, and accompanying documentation (collectively, the “Software”). By installing, copying, activating, or using the Software — including by clicking “I agree” during installation — you accept this Agreement. If you do not agree, do not install or use the Software.

2. Definitions#

• Software — the CADKeeper Windows desktop application in object-code form, its installer, updates, and documentation.
• Tier — the Free, Core, or Pro level of access that determines the features and limits available to you, as described in Section 4.
• License Key — the credential that unlocks a paid Tier and identifies your license.
• Your Content — the files, folder structures, naming rules/rulesets, and change-log history you create or process with the Software.

3. License grant#

The Software is licensed, not sold. Subject to your compliance with this Agreement, we grant you a personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the Software in object-code form for your own auditing and file-management purposes, at the Tier you are entitled to. All rights not expressly granted are reserved by us.

4. Tiers & scope of use#

Your license scope is set by your Tier. The Tiers nest — each higher Tier includes everything below it:

• Free. The complete crash-safe workflow — audit, batch rename and auto-fix, reversible change log, one-click rollback, custom rules, the cleared standard templates, and duplicate detection for DWG, DXF, and PDF — with the apply operation capped at 10 files per run. No License Key, no payment, and no expiry. The cap is a per-run limit, not a cumulative one.
• Core. A one-time, perpetual license that removes the Free cap: the same workflow, uncapped, for DWG, DXF, and PDF, with one active ruleset at a time, on up to two devices. There is no subscription and no forced expiry.
• Pro. A recurring subscription that adds the ongoing-value features — real-time folder watch, compliance audit-trail reports, XREF-impact checks, folder reorganization, AI-assisted rule and naming suggestions, and the full file-type breadth (including RVT, IFC, STEP, and DGN) — also on up to two devices. Pro's first year includes a perpetual Core license (existing Core owners may instead add Pro at the lower renewal price). The recurring Pro features continue only while your subscription is active; the underlying Core license is perpetual and yours to keep.

Two devices, one person. A paid License Key may be active on up to two devices at a time — typically a workstation and a laptop — both belonging to the same person. You can move your license to a different machine at any time (see §5). Unless a separate written volume or team agreement says otherwise, you may not share a single License Key across more than one person.

5. License Keys, activation & online validation#

Paid Tiers are unlocked with a License Key issued to you after purchase. Activating the Software registers the device you activate it on, and a paid License Key may be active on up to two devices at a time (§4).

Both paid Tiers check in with our license server, and you authorize the Software to do so. Pro validates and renews periodically, confirming that your subscription is current. Core checks in far less often — at most about once a week, and for one purpose only: to learn whether the License Key has been refunded or revoked. Neither check sends anything about your drawings. Each sends your License Key and the random device code, and nothing else; we describe this in our Privacy Policy.

Neither check can disable the Software for want of a connection. A Core license does not expire. If the Software cannot reach us — no internet, a firewall, an outage on our side, an air-gapped machine — it keeps working normally, indefinitely, and never downgrades itself on that basis. The only thing that removes a license from a device is an explicit response from us saying that license was refunded or revoked. We will not disable the Core Tier wholesale. If we ever permanently retire the license server, we will first release an update that removes the periodic check, so activated copies keep working without it.

If your Pro subscription lapses or is cancelled at period end, your access drops to the Core Tier — never to Free — and the Pro-only features become unavailable. Because your first-year purchase includes a perpetual Core license, that Core access is permanent.

Refunds. A full refund ends your right to use the paid Tiers. When you take a refund we revoke the License Key, and the Software returns to the Free Tier at its next check-in. Where the Software cannot reach us to do that, you agree to stop using the paid Tiers and to remove the license from your devices (in the app: gear icon → License → Deactivate this device).

You agree not to interfere with, block, or falsify the activation or validation mechanism.

Moving your license to another machine. If both device slots are in use and you want to use a third machine, one of the two has to give up its slot. Either deactivate the license from the machine you're retiring (in the app: gear icon → License → Deactivate this device), or, if that machine is gone, lost, or reimaged, choose the slot to release in the app and confirm with a one-time code we email to your purchase address. There is no charge for moving a license, and no limit on doing so within reasonable use. If you no longer control your purchase email address, contact email support and we will move it for you.

No internet on the machine you want to use? You can activate it offline at cadkeeper.com/activate from any other device — this issues a license file for that one machine, and it takes a device slot the same way an online activation does.

6. Restrictions#

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

• resell, rent, lease, lend, sublicense, distribute, or otherwise transfer the Software or your License Key;
• share a License Key across more devices or users than your Tier permits, or use it to provide a service bureau or hosted offering to third parties;
• circumvent, disable, remove, or tamper with the Tier caps, License Key checks, or the license validation/renewal mechanism;
• reverse-engineer, decompile, disassemble, or otherwise attempt to derive the source code of the Software, except to the limited extent this restriction is prohibited by applicable law or permitted by the license of an included open-source component (Section 9);
• modify, adapt, translate, or create derivative works of the Software, or remove or alter any proprietary notices; or
• use the Software to violate any law or to process files you have no right to modify.

7. Ownership#

The Software is ours. We and our licensors retain all right, title, and interest in and to the Software, including all intellectual-property rights. This Agreement gives you a license to use it — not any ownership of it.

Your Content is yours. We claim no ownership of and no rights over your files, your rulesets, or your change-log history. The Software runs on your machine and processes your files locally; we do not require you to send Your Content to us to use it.

8. Updates#

We may make updates, bug fixes, and new versions of the Software available from time to time. Updates are provided under this Agreement unless they are accompanied by a separate license, in which case that license governs the update. We are not obligated to provide any particular update, and we may change or discontinue features. Installing an update may be required for continued licensing checks to function.

9. Third-party & open-source components#

The Software includes third-party and open-source components that are licensed to you under their own terms, not this Agreement. The applicable notices and license texts are made available within the Software (for example, in an “About › Open-source licenses” screen) and/or accompany the installer. To the extent an open-source license grants you rights that conflict with a restriction in this Agreement, that open-source license controls for that component only. Nothing in this Agreement limits your rights under, or is intended to override, any such open-source license.

10. Your files are your responsibility — keep backups#

The Software renames and moves real engineering files, and file operations are inherently risky. You are responsible for maintaining your own backups, and we strongly recommend running the Software only on files you have backed up.

The Software is designed to reduce that risk: every destructive operation is preceded by a dry-run preview you must explicitly approve, is recorded in a change log with full before-and-after paths, and is reversible via one-click rollback. These safeguards materially lower the chance of a bad outcome but do not eliminate it and do not replace your own backups. You bear final responsibility for your data.

11. Warranty disclaimer#

The Software is provided “as is” and “as available,” without warranties of any kind, whether express, implied, or statutory, including any implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. We do not warrant that the Software will be error-free or uninterrupted, that defects will be corrected, or that any audit, rename, move, or rollback will produce a particular result. Some jurisdictions do not allow the exclusion of certain warranties, so parts of this section may not apply to you.

12. Limitation of liability#

To the maximum extent permitted by law, in no event will Trelawny Enterprises LLC or its licensors be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of data, files, profits, revenue, goodwill, or business, arising out of or related to the Software or this Agreement, even if advised of the possibility of such damages. Our total aggregate liability for all claims relating to the Software will not exceed the amount actually paid for the Software in the twelve (12) months before the event giving rise to the claim — which, for Free-Tier users, is zero. These limitations apply regardless of the theory of liability and are a fundamental basis of the bargain between us.

13. Term & termination#

This Agreement is effective until terminated. It terminates automatically if you breach it. We may also suspend or terminate your license if you materially breach this Agreement — for example, by tampering with the licensing system or reselling keys. On termination you must stop using the Software and remove all copies. Sections that by their nature should survive — including Sections 6, 7, 9 through 15, and 16 — survive termination. Termination of a Pro subscription reverts you to the Core Tier, as described in Section 5.

14. Export & U.S. government rights#

You represent that you are not located in, and will not use or export the Software in violation of, any applicable export-control or sanctions law. If the Software is licensed to or on behalf of the U.S. Government, it is “commercial computer software” and “commercial computer software documentation,” and the Government receives only the rights granted to all other end users under this Agreement.

15. Governing law & general terms#

This Agreement is governed by the laws of the State of Texas, without regard to its conflict-of-laws rules. Any dispute arising out of or relating to this Agreement or the Software will be brought exclusively in the state or federal courts located in Texas, and you consent to the personal jurisdiction of those courts.

This Agreement, together with our Terms of Service, Privacy Policy, and Refund Policy, is the entire agreement between you and us regarding the Software and supersedes any prior agreement on that subject. If any provision is found unenforceable, the rest remains in effect and the unenforceable provision is enforced to the maximum extent permitted. Our failure to enforce a provision is not a waiver. You may not assign this Agreement; we may assign it in connection with a merger, acquisition, or sale of assets. We may update this Agreement as the product evolves; the version presented with the Software you are using, or posted at this page, applies.

16. Copies obtained through the Autodesk Design and Make Marketplace#

This section applies only if you obtained the Software through the Autodesk Design and Make Marketplace (the “Marketplace”, formerly the Autodesk App Store). It adds to, and does not replace, the rest of this Agreement. In it, “Autodesk” means Autodesk, Inc. and its subsidiaries and affiliates.

• (a) Who this Agreement is with. This Agreement is entered into between you and Trelawny Enterprises LLC only — not with Autodesk. We, and not Autodesk, are solely responsible for the Software, for any content related to it, and for any maintenance or support obligations relating to it. Autodesk has no obligation to furnish any maintenance or support for the Software. Your use of the Software is governed solely by this Agreement.
• (b) Warranty. We are solely responsible for any warranties relating to the Software, whether express or implied by law, to the extent not effectively disclaimed in Section 11. Autodesk has no warranty obligation whatsoever with respect to the Software, and any claims, losses, liabilities, damages, costs, or expenses attributable to any failure to conform to any warranty are our sole responsibility.
• (c) Claims relating to the Software. We, and not Autodesk, are responsible for resolving any claim by you or any third party relating to the Software, including claims for (i) product liability, (ii) noncompliance with any applicable law, including consumer-protection, privacy, security, and data-protection law, and (iii) infringement or misappropriation of the intellectual-property or other rights of a third party.
• (d) Your age and authority. The Software is not directed, in whole or in part, to individuals under the age of 18. You represent and warrant that you are at least 18 years of age, or the equivalent age of majority in the jurisdiction in which you reside, and that you have the right, authority, and capacity to bind yourself or, if you are acting on behalf of a company or other legal entity, to bind that company or entity to this Agreement.
• (e) Autodesk is a third-party beneficiary. Autodesk is a third-party beneficiary of this Agreement, and upon your acceptance of it Autodesk has the right — and is deemed to have accepted the right — to enforce this Agreement against you as a third-party beneficiary. This subsection survives termination of this Agreement.
• (f) Where to direct questions. All questions, complaints, and claims with respect to the Software go to us, not to Autodesk, at the name, address, and email in Section 17.

Nothing in this Agreement makes Autodesk a party to it, and Autodesk does not endorse the Software. “AutoCAD,” “Revit,” “AIA,” “National CAD Standard,” “ISO” and “BS” are trademarks of their respective owners and are referenced only to identify the products and standards the Software is compatible with. CADKeeper is an independent product and is not endorsed by, affiliated with, or sponsored by any of them.
