Privacy Policy

This Privacy Policy explains how Sipers Mechatronics (eenmanszaak) ("we", "us") collects and uses personal data when you visit this website or purchase digital products related to the MechAMS system.

The data controller is Sipers Mechatronics, a sole proprietorship (eenmanszaak) established in the Netherlands. Chamber of Commerce (KvK) number: 98949578. VAT ID: NL005363496B77. You can contact us at contact@sipersmechatronics.com for general questions or support@sipersmechatronics.com for product and technical support. We aim to respond within 1–3 business days.

Data we collect

We only collect data that is necessary to operate this website, sell digital products, and provide support:

  • Website usage data: When you visit the site, basic technical information such as IP address, browser type, device type, and pages visited may be logged by our hosting provider and by Vercel Web Analytics. This helps us keep the website secure and understand general performance.
  • Contact and support data: If you email us (for example via contact@sipersmechatronics.com or support@sipersmechatronics.com), we receive your email address and the contents of your message. Email is handled through Google Workspace.
  • Purchase-related data: When you purchase a product, checkout and payment are handled by Stripe. We receive information from Stripe such as which product you bought, pricing, currency, billing country/address, any tax IDs you provide, your email address, and the resulting invoice so we can provide support and maintain VAT/accounting records. We do not receive or store full payment card details — these stay with Stripe.

Legal bases under GDPR

We process personal data on the following legal bases under the General Data Protection Regulation (GDPR):

  • Performance of a contract: To process and deliver your purchases, provide downloads, and offer customer support.
  • Legal obligation: To keep records for tax and accounting purposes as required under Dutch/EU law.
  • Legitimate interest: To operate, maintain, and secure the website, understand basic usage patterns in an aggregated way, and prevent abuse.
  • Consent: Where you explicitly opt in to any optional communications (for example, email updates), which you can withdraw at any time.

Third-party services

We rely on a small number of third-party services to run this website and deliver products:

  • Vercel: Hosts the website and provides privacy-friendly analytics (Vercel Web Analytics). Vercel processes IP addresses and basic request data to serve pages and provide aggregated usage statistics.
  • Stripe: Handles checkout, payment processing, VAT/sales-tax calculation, and invoicing. Stripe is an independent controller for the payment data it collects on its own platform. Please refer to Stripe's own privacy policy and terms for details about their processing, including international transfers of card data.
  • Google Workspace: Provides email hosting for our @sipersmechatronics.com addresses. Emails you send to us are stored and processed through this service.

Cookies and tracking

This website does not use Google Analytics, Meta/Facebook pixels, TikTok pixels, or similar marketing-tracking cookies. Vercel Web Analytics is designed as a privacy-friendly, first-party analytics solution and does not track individual users for advertising purposes. When you proceed to Stripe Checkout, Stripe may set its own cookies on its checkout domain for fraud prevention and session purposes, which is covered by Stripe's own cookie and privacy notices.

Data retention

We retain personal data only for as long as necessary for the purposes described above or as required by law:

  • Purchase and accounting data are typically stored for at least seven (7) years to comply with Dutch/EU tax and accounting obligations.
  • Support and contact emails are stored for as long as reasonably necessary to handle your request and maintain a basic support history, unless you ask us to delete them where legally possible.
  • Technical logs and analytics data are retained for a limited period that is proportionate to security, troubleshooting, and performance needs.

Your rights

If you are located in the EU/EEA, you have the following rights with respect to your personal data, subject to applicable law:

  • Right of access to your personal data.
  • Right to rectification of inaccurate or incomplete data.
  • Right to erasure ("right to be forgotten") in certain circumstances.
  • Right to restriction of processing in certain circumstances.
  • Right to data portability, where technically feasible.
  • Right to object to certain processing, particularly where we rely on legitimate interests, and the right to withdraw consent where processing is based on your consent.

To exercise these rights or ask questions about this policy, please contact us at support@sipersmechatronics.com or contact@sipersmechatronics.com.

You also have the right to lodge a complaint with your local supervisory authority. In the Netherlands, this is the Autoriteit Persoonsgegevens (Dutch Data Protection Authority), which can be contacted via autoriteitpersoonsgegevens.nl.
