Privacy Policy
Last updated: 2026-01-01
In summary
- Free service, no account, no registration. We do not ask for your name, email, password, or bank details to use the service.
- No cookies. Neither first-party, third-party, advertising trackers, nor audience measurement tools. There is therefore no cookie banner, because there is nothing to consent to.
- The only storage on your browser is strictly functional local storage that keeps your work in progress during your visit.
- Your files are not intended to be retained permanently. They are not used to train any model, are not resold, published, or shared with third parties.
- Conversion is a deterministic algorithm, without artificial intelligence and without profiling.
1. Data Controller
1.1
The data controller is Daedalus Concepts Systems, microenterprise, 348 rte de Bord, 24470 Champs-Romain, SIREN 491 871 737, publisher of the Brick Converter service (brick-converter.com).
1.2
Contact for any questions or requests regarding your data: contact@brick-converter.com.
2. Data Processed
2.1 Files and Content You Provide
| Data | Source | Details |
|---|---|---|
| 3D GLB Model | You submit it | file uploaded for conversion |
| Conversion Parameters | You choose them | target height, rotation, smoothing |
| Working Data | Generated by the service | voxels, paint, bricks, base, instructions, assembly plans |
| Submitted Filename | Transmitted by your browser | used to name working files |
These files normally contain no personal data. Never send sensitive data (health, opinions, biometric data).
2.2 Technical Data
Requests are logged to console output (stdout/stderr) for diagnostics and security purposes. The service itself does not persist these logs to disk. The hosting provider's (Contabo) system logs may exist according to their own policy.
2.3 No Payment Data
The service is entirely free: there is no online payment, no payment provider, no billing. We collect no bank details.
2.4 Correspondence
If you write to us, we process your email address and message content for the time necessary to handle your request.
2.5 What We Do Not Collect
No account, no permanent visitor identifier, no cookies, no audience measurement, no advertising tracker, no tracking pixel, no social media button, no bank data, no data resale, no commercial prospecting.
3. Purposes and Legal Basis
| Purpose | Data | Legal Basis (GDPR) |
|---|---|---|
| Convert your model and produce deliverables | files, parameters, working data | contract performance — art. 6.1.b |
| Operate and secure the service, diagnose incidents, prevent abuse | technical logs | legitimate interest — art. 6.1.f |
| Respond to your messages | correspondence | legitimate interest — art. 6.1.f |
| Process illegal content reports | relevant files, report | legal obligation / legitimate interest — art. 6.1.c and f |
We never use your files to train an artificial intelligence model, or to build a gallery, dataset, or public examples.
4. Retention Periods
4.1 Working Files
During conversion, the service writes to the server: the GLB file you submitted (and an unmodified copy for rotations), the voxel file, and files derived from your work session (paint, bricks, editing, base, instructions, assembly plans). This is necessary for operation: your work must survive from one step to the next.
4.2 Deletion
These files are deleted:
- automatically, as soon as you recalculate the same model at a different height — the old version is then completely erased;
- automatically, during the daily sweep (daily at 00:00 UTC), as soon as the file has not been accessed for more than one hour — at most approximately 25 hours after last use;
- immediately, upon your request to
contact@brick-converter.com, to the extent the file can be identified.
4.3 Technical Logs
Technical logs are written to console output (stdout/stderr) only, for real-time diagnostics. They are not persisted to disk by the application. The hosting provider (Contabo) may retain its own system logs according to its hosting policy. The service itself does not record or persistently store IP addresses.
4.4 Correspondence
Email exchanges are retained for the time necessary to handle your request.
4.5 No Accounting Data
Since the service is free, we issue no invoices and retain no customer data under accounting or tax obligations.
5. Recipients and Processors
5.1
Your data is neither sold, rented, nor transferred to third parties for commercial purposes.
5.2 Processors
| Processor | Role | Location |
|---|---|---|
| Contabo GmbH | server hosting | European Union (France, Lauterbourg data centre) |
This is the only processor: since the service is free and has no account, there is no payment provider, email service, audience measurement tool, or third-party analytics service.
5.3 Brick Resellers
After conversion, you may be redirected to an independent third-party reseller. We transmit no personal data to them, and they transmit none to us — including if you place an order: we receive an affiliate commission from them (Terms of Service, section 5.4), calculated on sales amounts, with no named or identifying information about you. To attribute your order to our link, that retailer sets a cookie on its own website when you arrive there: that cookie is required for the affiliate programme to work, without it the order cannot be attributed. It is theirs, not ours: no cookie is set on Brick Converter. The bill of materials file is deposited by you on their site, under your own responsibility. This reseller is an autonomous data controller: their own privacy policy applies when you are on their site.
5.4
We may be required to share data with an administrative or judicial authority when the law requires it.
6. Cookies and Browser Storage
6.1 No Cookies
The service does not set any cookies: neither first-party, third-party, audience measurement, nor advertising trackers. No third-party analytics script is loaded. No consent banner is therefore necessary.
6.2 Functional Local Storage
The service uses your browser's local storage (sessionStorage and localStorage) to preserve the state of your work in progress during your visit. This information is strictly necessary for the operation of the requested service: it remains on your device, is not transmitted to any third party, and is not used to identify you, track you, or serve advertising. sessionStorage disappears when you close the tab.
7. Data Location and Transfers
7.1
The service is hosted on a server located in the European Union (France, Lauterbourg data centre — Contabo GmbH).
7.2
No data is transferred outside the European Union. The service uses no processors established outside the EU.
8. Security
8.1
We implement technical and organizational measures appropriate to the nature of the service: encryption of exchanges (HTTPS), restricted server access, limitation of collected data to the bare minimum.
8.2 Architecture — Session Isolation
A unique session identifier (8-character UUID) is assigned to each visitor. Filenames follow the format <stem>_h<height>_<uuid>.json. The UUID (8 hexadecimal characters) provides protection: approximately 4 billion combinations, which hinders random access. Do not submit confidential models to the service.
8.3 Measures in Place
- The UUID changes with each visit
- Files from a session are automatically deleted after 1 hour of inactivity
- Deletion requests remain actionable upon notice
8.4
In the event of a data breach presenting a risk to your rights and freedoms, we notify the supervisory authority and, when required by law, the affected individuals.
9. Your Rights
9.1
Under GDPR, you have the rights of access, rectification, erasure, restriction, opposition, and data portability.
9.2 How to Exercise Them
Write to contact@brick-converter.com. We respond within one month, extendable by two months for complex requests.
9.3 Limitation Specific to a Service Without Account
The service collects no identity: we cannot link a file to a person. For a request concerning a file to be actionable, you must provide the details necessary to identify it (submitted filename, chosen height, approximate date and time).
9.4 Complaint
You may file a complaint with the Commission Nationale de l'Informatique et des Libertés (CNIL, www.cnil.fr).
10. Automated Decision and Profiling
10.1
The conversion of your model into a brick sculpture is an automated and deterministic process: same inputs, same outputs. It contains no artificial intelligence and no learning from your files.
10.2
We practice no profiling, no behavioral segmentation, and no advertising personalization.
11. Minors
11.1
The service is intended for an adult audience. It is not designed for, intended for, or marketed to minors.
11.2
If we learn that a minor has submitted personal data to us, we delete it. A legal representative can notify us at contact@brick-converter.com.
12. Changes to This Policy
We may update this policy. The applicable version is the one published on the site; the last update date appears at the top of this document. In case of substantial change, we will indicate it prominently on the site.
