We use Vercel Speed Insights to improve loading, responsiveness and visual stability on public pages. Measurements include the page path, performance metrics and technical information such as browser, device, connection type and country.

We exclude contact and career pages, administration, private pages and signed-in visits. We do not send form contents or attachments with these measurements, and remove URL query parameters and fragments before sending them.

Vercel processes these measurements. According to its documentation, Speed Insights does not identify individual visitors or reconstruct browsing sessions across pages. Read Vercel’s Speed Insights privacy information.

We use Vercel Web Analytics to understand visits to our public commercial pages, including contact. We send the canonical page address without URL query parameters or fragments. Vercel also processes technical information such as browser, device, approximate location and referring website for aggregated statistics.

We also count clicks on manufacturing families and public downloads, and the start, validation errors and saving of commercial inquiries. Each event includes at most two predefined values: the page identity and, when applicable, the selected inquiry reason (quotation, evaluation or supplier). A download click does not confirm a completed download.

These measurements exclude names, email addresses, messages, attachments and inquiry identifiers. We exclude career pages, administration, private pages and signed-in visits. According to Vercel, Web Analytics does not use third-party cookies. Read Vercel’s Web Analytics privacy information.

Commercial inquiries request your identity, company, email and requirement; technical information and attachments are optional. Applications enabled through a vacancy use the employment details and résumé requested by that form.

Records are stored in the local SQLite database. Drawings and résumés are stored as private files outside public static folders. Authorized staff access them through the administration interface and its permissions.

The application uses sessions and CSRF protection for forms and administration. Website measurements with Vercel are described in the notices on this page. It records daily aggregate counts of form openings, errors and document download requests. These counters do not store names, email addresses, IP addresses, visitor identifiers or inquiry contents. External links are subject to their respective services’ terms.

A local confirmation demonstrates a test record, not receipt of a message by ETAR. Before production publication, responsibility, retention, data rights handling and applicable delivery services must be defined.
