Privacy Policy

Zenve3D is made by LOGZAI SRL, a limited liability company registered in Romania (“we”, “us”). We are the data controller for the personal data described in this policy.

• Registered office: Fagarasi 19, Dumbravita, Romania
• Tax identification number (CUI): 53038901
• Trade Register number: J2025094020008
• EUID: ROONRC.J2025094020008

You can reach us about anything on this page at hello@zenve3d.com.

The app works entirely on your device and contains no networking code. There is no account system, no licence check that phones home, no usage analytics, and no third-party analytics or crash-reporting SDK compiled into it. It does not contact us when you launch it, use it, or close it.

Specifically:

• Your models and sketches are saved as ordinary document files, in whichever location you choose when you save them. We never receive them.
• Your settings and preferences are stored locally on your device in the standard system preferences store. They are not synced to us.
• If you save a document to iCloud Drive — or any other location you pick in the system save dialog — that file is handled by Apple under your own iCloud account and terms. We have no access to it and no visibility into it.

Zenve3D can keep a replayable transcript of the modelling commands you run, so that a problem can be reproduced exactly rather than guessed at. This is the Record commands switch under Settings → Diagnostics, and it is on by default. The transcript is written inside your own project file and stays on your device. Turning the switch off stops the project collecting them.

Nothing is transmitted automatically. The transcript only ever leaves your device if you press Copy in that same settings pane and then send the result to us yourself.

Please read this before sending us a session script: the transcript opens with a copy of the document as it stood when the session began, so it embeds your model geometry. Send it only if you are comfortable sharing that design with us. If the model is confidential, describe the problem in words instead, or reproduce it in a throwaway document and send that transcript. When you do send one, we use it solely to reproduce and fix the problem.

The site is hosted by Vercel Inc., which processes standard server request logs — including IP addresses — on our behalf in order to serve the site and protect it from abuse. We do not use those logs to build any profile of visitors. Vercel acts as our processor under its own privacy policy.

We use Google Analytics 4 to understand how the site is used — how many people visit, which pages they read, and which calls to action they click. We use it to decide what to build and what to explain better, not to identify you.

Google Analytics only loads if you accept it when asked. Decline and no analytics script is loaded and no analytics cookie is set — the site works exactly the same. You can change your mind at any time; see Cookies below.

If you do accept, the following is collected:

• Pages you view, when, in what order, and the referring site or search that brought you here.
• Approximate location (typically country or city-level), derived from your IP address, plus your device type, browser, operating system and screen size.
• Which buttons you click. We record a named event when you use a call to action — currently the Mac and iPad download buttons and the “Join the beta” button — together with where on the page it was (header, hero or the beta section). This tells us which placements work; it says nothing about you personally.

Google acts as our processor for this and handles the data under its own privacy policy. This can involve transferring data outside your country, including to the United States, under the safeguards Google provides. Our lawful basis is your consent, which you may withdraw at any time.

We set no cookies of our own. The site needs none to function: there is no login, no basket and no session to remember.

If you accept analytics, Google Analytics sets its own cookies — _ga and a _ga_* cookie for this site — which give you a random identifier so repeat visits can be counted as one visitor rather than several. They contain no name, email or address. By default these expire two years after your last visit.

A small record of your own choice is also stored in your browser, so that we do not ask again on every page. That one is not analytics and is not shared with anyone.

To withdraw consent, use the Cookie settings link at the bottom of any page: it reopens the same question, and declining stops the analytics script from loading again. Clearing your browser’s cookies for this site also resets the choice, and you can block cookies entirely in your browser settings.

The beta is distributed through TestFlight, which is operated by Apple. Installing and running a beta build means using an Apple service, governed by Apple’s Privacy Policy, not this one. Apple decides what it collects there; we cannot change it.

What Apple passes on to us is narrow:

• Crash reports from beta builds, containing technical diagnostics such as device model, OS version and a stack trace. These describe the failure, not you.
• Feedback you choose to submit through TestFlight, including any comment and screenshot you attach. Screenshots may show whatever was on your screen, so take the same care as with a session script.

Because we invite testers with a public link, testers appear to us as anonymous — Apple does not give us your name or email address. We therefore hold no mailing list of beta testers and cannot email you.

If you write to us — a bug report, a feature suggestion, a question — we hold that message and your email address for as long as needed to deal with it and to keep a record of the decision. We use it only to reply and to improve Zenve3D. We do not add you to any marketing list.

• We do not sell or rent your personal data.
• We do not serve advertising, run ad networks, or use Google’s advertising or cross-device features. The analytics described above are used to count and improve, not to retarget you.
• We build no profile of you as an individual, and we never attempt to link analytics data to your identity.
• Nothing in the app is tracked at all — no telemetry, no usage analytics, no phoning home. The analytics on this page concern the website only.
• We do not use your models, designs or documents to train machine learning models.

We are established in Romania, so the EU GDPR applies to what we do — and equivalent rights apply if you are in the UK. You have the right to access your personal data, correct it, have it deleted, restrict or object to our use of it, and receive a copy of it in a portable form. Write to hello@zenve3d.com and we will respond within one month.

You may also withdraw your consent to analytics at any time, without giving a reason and without affecting anything else — see Cookies.

In practice there is usually very little to act on: unless you have emailed us or sent feedback, we are unlikely to hold anything that identifies you. Our lawful basis is consent for website analytics, and our legitimate interest in supporting and improving our own software and in keeping this website available and secure for everything else.

If you are unhappy with how we have handled your data, you can complain to our supervisory authority, the Autoritatea Națională de Supraveghere a Prelucrării Datelor cu Caracter Personal (ANSPDCP), Romania’s national data protection authority — dataprotection.ro. If you live elsewhere in the EU, you may also complain to your own national authority.

Zenve3D is a professional design tool and is not directed at children. We do not knowingly collect personal data from children.

Romania has not lowered the age set by Article 8 of the GDPR, so consent to our website analytics is only valid from the age of 16. Below that age it must be given or authorised by a parent or guardian. If you believe a child has given us personal data, write to hello@zenve3d.com and we will delete it.

Zenve3D is in active development, and this policy will change as the product does — particularly when accounts, cloud storage, collaboration or paid licences arrive, none of which exist today. We will update the date at the top of this page whenever it changes, and note anything significant in the release notes.
