Data Controller

Sychev-Lab is the data controller responsible for processing personal data through the website in compliance with Regulation (EU) 2016/679 (GDPR) and Organic Law 3/2018 (LOPDGDD).

  • Controller: Anton Sychev (Sychev-Lab)
  • Website: https://lab.sychev.xyz
  • Address: Barcelona, Spain
  • Contact email: anton@sychev.xyz

Data We Collect

Data may be provided directly by the user (e.g., when registering or making a purchase) or generated automatically when using the site.

  • Identification and contact data: name, surname, email address, billing address and, where applicable, shipping address.
  • Account data: access credentials and data associated with the user profile managed through Firebase Authentication.
  • Transaction data: products purchased, amount, currency, date and payment method (processed through Stripe).
  • Technical and usage data: IP address, browser type, device, pages visited, browsing time and actions performed on the website, through cookies and similar technologies.

Purposes of Processing and Legal Basis

  • Service provision and contract execution: manage user registration, allow account access, process orders, enable 3D model downloads and provide support.
  • Payment and billing management: process payments through Stripe, issue invoices and comply with accounting and tax obligations.
  • Customer service: respond to inquiries, incidents or information requests received through contact channels.
  • Service improvement and security: analyze site usage, improve user experience, prevent fraud and ensure platform security.
  • Service-related communications: sending informational emails about service changes, security notices or account updates.
  • Commercial communications (if applicable): sending information about news, offers or content related to Sychev-Lab, provided there is prior consent or legitimate basis.

Third-Party Services (Firebase, Stripe and Google Analytics)

These providers may process data within and, in some cases, outside the European Economic Area, applying appropriate safeguards under data protection regulations (such as standard contractual clauses or equivalent mechanisms).

  • Firebase (Google): used for authentication and user account management, as well as other backend functions. This involves processing identification and technical data associated with platform use.
  • Stripe: provides payment gateway services. Card data is communicated directly to Stripe, which acts as processor or controller according to its own privacy policy. Sychev-Lab does not store complete card data.
  • Google Analytics or other analytics tools: collect information about website usage through cookies, for statistical purposes and service improvement.

Retention Periods

Once the aforementioned periods have elapsed, data may be blocked solely for the purpose of addressing potential legal liabilities during applicable limitation periods.

  • As long as there is a contractual or registered user relationship with Sychev-Lab.
  • For the periods necessary to comply with legal obligations (e.g., tax and accounting periods provided in Spanish regulations).
  • Until the user requests deletion of their data, when processing is based on consent and there is no other legal basis justifying its retention.

Data Disclosure

  • Service providers acting as processors (e.g., hosting/Firebase, payment processors like Stripe, analytics and support services), with whom corresponding data processing agreements have been executed.
  • Public administrations, competent authorities and courts, when there is a legal obligation to disclose or it is necessary for the defense of rights and legitimate interests.

User Rights

  • Access: obtain confirmation as to whether their data is being processed and access thereto.

Intellectual Property and Use License (Reference)

The processing of personal data arising from the purchase and use of 3D models is carried out in accordance with this policy. Purchasing a 3D model does not imply transfer of intellectual property rights, but rather a license of use governed by Sychev-Lab's Terms and Conditions and each model's sheet.

Each model's detail will indicate whether the license is for personal use only or whether commercial use is permitted under certain conditions. Users should always review such terms before using the model.

Security Measures

Sychev-Lab applies appropriate technical and organizational measures to protect personal data against loss, misuse, unauthorized access, alteration or destruction, taking into account the state of the art, the nature of the data and the risks associated with processing.
