How We Handle Your Data
At Solidron, trust is the foundation of every project. That principle extends to our digital work. This policy outlines exactly how we collect, use, and protect the information you share with us—no jargon, just clarity.
Document Clarity
Our approach: precise, documented, and accountable.
What We Collect and Why
We only gather data necessary to deliver our services, improve your experience, and meet legal obligations. Our collection is purposeful—each data point serves a defined function in the project lifecycle.
Direct Contact & Project Inquiries
When you contact us via our online form, email, or phone, we collect your name, email address, phone number, and project details (type, location, scope). This is stored in our secure CRM system to manage initial consultations and provide accurate project estimates.
Website Analytics & Performance
We use privacy-focused analytics to understand how visitors navigate our site (pages viewed, time spent). This data is aggregated and anonymized; we cannot identify individual users. It helps us improve site performance and content relevance for property developers, homeowners, and architects.
Client Project Data
For active clients, we may process architectural plans, site addresses, and contractual information. This data is handled under strict confidentiality agreements and is retained only as required by French building codes (DTU) and tax laws, typically 5-10 years post-project.
Transparency
We disclose every data point we collect and its specific purpose.
Security
Industry-standard encryption protects data in transit and at rest.
Control
You can request access, correction, or deletion of your personal data.
Legal Framework & Constraints
Our data handling is governed by strict French and EU regulations. We operate within these boundaries, which also shape our project planning and client agreements.
GDPR Compliance
We are fully compliant with the EU's General Data Protection Regulation.
French Data Protection Act
Adherence to CNIL (Commission Nationale de l'Informatique et des Libertés) guidelines.
Project Retention Periods
Data kept for contractual and legal necessity (e.g., 10-year warranty obligations).
Failure Modes & How We Avoid Them
Mistake: Vague Consent
Using broad, pre-ticked checkboxes that don't specify data usage.
Solidron Approach
Granular, explicit consent for each data type. Every contact form clearly states how your information will be used.
Mistake: Indefinite Storage
Keeping client data forever "just in case."
Solidron Approach
Automated review cycles. Data is purged after legal retention periods expire, unless a client requests otherwise.
Mistake: Third-Party Negligence
Sharing data with unvetted software vendors.
Solidron Approach
All vendors undergo strict security assessments. We use Data Processing Agreements (DPAs) as a standard requirement.
Our Evidence Lens
A framework for critical decisions, borrowed from our construction methodology.
Assumptions
- • Users expect clarity, not legal complexity.
- • Data security is a baseline expectation for a professional service provider.
- • Building trust requires transparency in both construction and data handling.
Constraints & View Changes
Our Core Constraint
We cannot comply with data requests that violate French building codes or EU security laws.
What Changes Our View
A formal court order or a CNIL directive would compel us to adjust our data retention for a specific client case. We would also change our view if a trusted third-party vendor suffers a verified breach.
This lens is applied to our privacy policy review, just as it is applied to material selection and project timelines.
Your Data Rights
As a data subject, you hold specific rights under the GDPR. We are committed to facilitating these requests promptly.
Right of Access
Request a copy of all personal data we hold about you.
Right to Rectification
Correct inaccurate or incomplete information.
Right to Erasure
Request deletion of your data (subject to legal obligations).
Right to Object
Object to processing for direct marketing or legitimate interests.
