Beta Licence (EULA) and Data Terms

ClashFree beta: end-user licence agreement (EULA)

Version 0.1, 2026-10-23. Applies to the closed ClashFree beta for Autodesk Revit 2023 to 2027.

1. Agreement

These terms are an agreement between you and the ClashFree author ("we"). You accept them by clicking "I accept the agreement" in the installer, by ticking the box when you sign up for the beta on our website, or by activating ClashFree in Revit. If you do not accept them, do not install or use ClashFree. If you use ClashFree for a company, you confirm that you may accept these terms for it.

The ClashFree beta data terms (beta-data-terms, on our website at clashfree.app/terms and installed with ClashFree) are part of this agreement.

2. Licence

We give you a personal, non-exclusive, non-transferable and revocable licence to install and use ClashFree to evaluate it, on your own computers, for the length of the beta and of your trial (section 4). An invite code is for you only.

3. What you may not do

Copy, sell, rent, lend, share or redistribute ClashFree, its installer or your invite code.
Reverse engineer, decompile or disassemble ClashFree, except where the law allows it despite this term.
Remove, disable or work around the trial, the beta expiry, the activation or any other lock or limit.
Use ClashFree, its proposals or its prompts to build a competing product.
Use ClashFree against the law or the rights of others.

4. Beta, trial and changes

ClashFree is a pre-release beta. It may contain errors, change or stop at any time, and is not supported like a released product.

restart it.

Activation needs your e-mail address, which we verify with a code.
Your trial lasts 15 days from your address's first activation, unless we tell you otherwise. Reinstalling does not

Each beta build stops making new AI proposals 120 days after it was built. Install the latest beta to continue.
When ClashFree locks, an open preview can still be rejected, so your model is never left half-changed.

5. Your models and your responsibility

ClashFree proposes changes to your Revit model, previews them and verifies them, and changes the model only when you confirm each fix. You stay responsible for your model and your design: review every fix before you keep it, and have a qualified person check that kept fixes meet the project's requirements, codes and standards. ClashFree does not give engineering or other professional advice. Keep backups of your models.

Linked models and other trades' elements are never edited; ClashFree flags them for a person to decide.

6. AI providers

ClashFree uses the AI you set up: your own API key (for example Anthropic) or your own Claude plan over MCP. Your AI requests go from your computer straight to that provider, under that provider's terms and costs. They do not pass through our server.

7. Data

The data terms say in full what ClashFree sends, why, where it is kept, for how long and how to delete it. In short:

Usage analytics and scrubbed diagnostics: a condition of the beta. While ClashFree is activated it sends counts and codes about how you use it, for example: how many clashes were checked with AI, which fix strategy was proposed, whether each fix was kept, rejected or flagged, which disciplines and element categories the models contain, timings and times of use, errors, and ClashFree's own log lines with every name, path and title removed or hashed. No model, file, project, user or machine names, no chat text and no AI prompts or answers. These data are how we learn whether the beta works; you cannot turn them off while you use the beta, but you can stop at any time by uninstalling ClashFree and deleting your data (section 12).
Clash content: on by default, your choice to turn off. "Share clash content to improve ClashFree" is on when you install; after activation ClashFree tells you so once, and you can turn it off at any time in Settings. While it is on, each Keep and Reject also sends the clash's content: the element categories, sizes and positions in millimetres, their surroundings, the AI's proposal and explanation, your chat about it and how Revit verified it, scrubbed of names, paths and titles. With it off, after a Reject ClashFree may ask whether you want to share that one rejection; nothing is sent unless you say yes, and "Don't ask again" stops the question.
Your e-mail address is used to activate ClashFree, run your trial and contact you about the beta. It is never part of usage analytics, diagnostics or clash content.

8. Feedback

If you send us feedback, ideas or bug reports, we may use them freely, without paying you or naming you.

9. Ownership

ClashFree, its code, prompts and documents belong to us or our licensors; this agreement gives you only the licence in section 2. Your models, reports and project data stay yours.

10. No warranty

ClashFree is provided "as is" and "as available", without any warranty, express or implied, including fitness for a particular purpose, accuracy and non-infringement, as far as the law allows.

11. Limitation of liability

As far as the law allows, we are not liable for any indirect, incidental, special or consequential loss, lost profit, lost data, delay or cost of redesign. Nothing in this agreement limits liability that cannot be limited by law.

12. Ending

You may stop at any time: in ClashFree, Settings, "Delete my data on the server" deletes what your installation sent, then uninstall. We may end the beta or your access at any time, for example after a breach of section 3. Sections 3 and 5 to 11 continue after the end.

13. Changes to these terms

We may change these terms. A new version is shown before it applies and must be accepted again (in the installer, at sign-up or at activation) to keep using ClashFree.

14. Law

This agreement is governed by the laws of India. The courts at Pune, Maharashtra, have exclusive jurisdiction over any dispute under it.

ClashFree beta: data terms

Version 0.3, 2026-10-25. These terms apply to the ClashFree beta for Autodesk Revit 2023 to 2027, to signing up for it on clashfree.app and to the website's contact form, and are part of the ClashFree beta EULA (eula).

1. Who we are

ClashFree is a beta add-in for Autodesk Revit. "We" means the ClashFree author, who runs the beta and its server. Contact for any data question or request: [email protected].

2. What is a condition of the beta, and what is your choice

installer, at sign-up and at activation). They are sent while ClashFree is activated; there is no switch for them. To stop them, delete your data on the server and uninstall (section 6).

(a) Usage analytics and scrubbed diagnostics: a condition of the beta. You accept them with the EULA (in the

ClashFree" is on when you install; after activation the pane tells you so once, with a link to Settings, and you can turn it off at any time. While it is on, every Keep and Reject sends its clash content (section 3), and so does a clash the AI flags for a person or a Keep that fails. With it off, after a Reject ClashFree may ask "Share this rejection to improve ClashFree?": Yes sends that one rejection, No sends nothing, and "Don't ask again" stops the question (Settings can turn it back on).

(b) Clash content: on by default, your choice to turn off. ClashFree, Settings, "Share clash content to improve

Nothing is sent before you activate the beta.

Signing up on clashfree.app needs your name, work e-mail address, company, job title, country and role; you may add your company size, discipline, Revit version, how you heard of ClashFree and a note. We also keep the country your IP address belongs to (not the address). We use them to send your confirmation link and invite code, to run, extend and end your trial, to remind you 3 days before it ends and when it has ended, to contact you about the beta and to understand who tests ClashFree. Your invite code works only with the e-mail address you signed up with.

Activation needs your e-mail address and an invite code: we e-mail you a 6-digit code to confirm the address. We keep the address to know who tests ClashFree, to run the 15-day trial per tester and to contact you about the beta. It is never part of usage events or diagnostics.

The website's contact form sends us your name, e-mail address, optional company, the topic and your message, with the country of your IP address; we use them only to answer you. The website sets no advertising or analytics cookies.

3. What is sent, and what is not

(a) Usage analytics are counts and codes, each with the time it happened: the ClashFree, Revit and Windows versions and the display language; per imported report, counts of issues and groups; per clash, the element categories, size and length bands, system class and the trade you work in; which fix strategy was proposed, whether its preview verified, whether it was kept, rejected or flagged, how many chat revisions, timings, AI token counts and cost; queue and MCP session counts; error types with a hash of ClashFree's own code lines. A random install id identifies your installation. The model and clash ids are replaced by a hash made with a key that never leaves your computer.

(a) also covers diagnostics: once a day, ClashFree's own log lines as message templates (for example "Drag: {Detail}"). Numbers and fixed codes are kept; every other value is replaced by a hash, and the text is scrubbed of file paths, user, machine and model names and e-mail addresses. Errors keep only the names of ClashFree's own functions. When you press "Send diagnostics now" you may add a note; it is scrubbed the same way.

(b) Clash content, only as section 2 says: one record per Keep, Reject, flag or failed Keep with what the AI saw and did: the clash's elements (category, kind, size, element ids, positions and distances in millimetres), the free space and obstacles around them, the scored fix options, the AI's proposal and explanation, your chat about the clash, how Revit verified the preview and your decision. With it: every earlier proposal and preview on that clash, your description of the clash, the random install and Revit session ids, the ClashFree and Revit versions, the AI model and effort, its token counts, cost and time, and the same hashed clash and model ids as the usage events, so a record can be matched to them. Before it leaves your computer, every name-like value (element, family, system, room, level, clash test, file and issue names, titles, marks, comments, GUIDs) is replaced by a hash, and every text is scrubbed of file paths, your user and machine names, model titles and e-mail addresses. Element ids are kept; they mean nothing without your model.

Never sent: your Revit models, BCF or clash reports, project, file, model, user or machine names, preview images, profiles, your AI provider API key; chat text and AI answers only as clash content (b).

Your AI requests go from your computer straight to the AI provider you configured, under that provider's terms. They do not pass through our server.

Activation and the trial: your e-mail address and the invite code go to our server once, and our e-mail provider (Resend) sends you the 6-digit code. ClashFree is usable for 15 days from your address's first activation; after that it locks (an open preview can still be rejected). Reinstalling does not restart the trial.

Update check: once a day ClashFree asks our server for the latest version. This request carries only the version you run (and, as any internet request, your IP address); it is made whatever your choice. When a newer build replaces yours, ClashFree renews its install token once, sending the install id and the new version.

4. Why

To learn whether ClashFree helps: how often a proposed fix is kept without a revision, how many revisions a clash needs, whether fixes create new clashes, and which errors to fix first. Not for advertising, not sold, not shared with third parties other than our hosting provider and our e-mail provider (only to send our e-mails: the sign-up link, the invite, the activation code, trial reminders and answers to your messages).

5. Where and how long

The server runs on Cloudflare (Workers, D1, R2). Diagnostics files and installers are stored in the EU (R2 EU jurisdiction).

beta ends, or deleted on request with your trial and activation records.

Usage events: deleted 13 months after they happened.
Diagnostics files: deleted 90 days after upload.
Clash content: deleted 13 months after upload.
Which EULA version you accepted and when (at sign-up and at activation): kept with your sign-up and activation records.
Your sign-up record: deleted 30 days after sign-up if you never confirm your e-mail address; otherwise kept until the

until the beta ends. "Delete my data on the server" deletes the install's record; your e-mail address and trial dates are kept so the trial is not restarted, and are deleted on request to the contact above.

Contact form messages: deleted 12 months after we receive them.
Your activation record (random install id, a hash of your invite code, your e-mail address, version, dates): kept

On your computer, unsent events wait in %LocalAppData%\ClashFree\telemetry\queue and unsent clash content in %LocalAppData%\ClashFree\telemetry\content (at most 50 records); both are dropped after 30 days, and turning (b) off deletes the unsent clash content.

6. Your rights

record and the activation record of your install at once and stops sending; then uninstall. Or write to the contact above.

See what is collected: Settings, Usage, "Open queue folder" shows the exact events before they are sent.
Stop clash content: turn (b) off, or answer No to the Reject question.
Stop everything: Settings, Beta, "Delete my data on the server" deletes every event, diagnostics file, clash content

so delete that first.

Uninstalling ClashFree offers to remove its local data (%LocalAppData%\ClashFree); it does not delete server data,

7. Beta

ClashFree is a beta. Each build stops making new AI proposals 120 days after it was built; install the latest beta to continue. Changes to these terms are announced in the pane before they apply.
