Privacy Policy

KleanPay SàrlVersion 2.0 — June 2026

1. Introduction

KleanPay Sàrl is committed to protecting user privacy. This Policy explains how we collect, use, store, share and protect personal data when you use the KleanPay platform.

The platform allows professional Sellers to receive escrow payments and authorised Buyers, companies or private individuals, to fund projects and milestones. Payment flows, fund holding and regulatory checks are operated by OPP Worldline.

2. Controller

Company:
KleanPay Sàrl
Address:
Chemin des Taborneires 8, 1350 Orbe, Switzerland
Email:
contact@kleanpay.ch

For identity verification, KYC/KYB, payment and escrow data processed directly by Online Payment Platform B.V. (OPP / Worldline), OPP acts as an independent controller or regulated provider depending on the processing concerned.

3. Legal framework

This Policy is primarily governed by the Swiss Federal Act on Data Protection (FADP) and its implementing ordinance.

The GDPR may apply additionally when data of persons located in the European Union is processed or when a provider is subject to it.

6. Hosting and data location

KleanPay’s main application data is hosted in a self-hosted Convex deployment operated on servers located in Switzerland. This infrastructure serves as the database, application backend, server functions and business source of truth for the Platform.

Production backups are encrypted and stored in a Swiss region separate from the main server, according to the internal backup and disaster recovery policy.

Escrow funds are never held by KleanPay or Convex. Monetary flows and segregated accounts are operated by OPP Worldline.

  • Timestamped logging of sensitive actions and append-only audit trail.

11. Cookies, sessions and tracking

The Platform uses cookies and similar technologies strictly necessary for authentication, session management, security, fraud prevention and service operation.

We do not use third-party advertising cookies. If analytics tools are enabled, they are configured to limit data collection and favour aggregated or pseudonymised measurements.

12. Automated decisions

KleanPay does not make fully automated individual decisions producing significant legal effects. Alerting rules may flag a transaction or account for human review in security or fraud prevention matters.

OPP may apply its own automated compliance, payment or fraud prevention controls as part of its regulatory obligations.

13. Protection of minors

KleanPay services are not intended for persons under 18. We do not knowingly collect personal data from minors.

14. Data breaches

In the event of a data breach likely to create a high risk, KleanPay will notify the Swiss Federal Data Protection and Information Commissioner (FDPIC) as soon as possible in accordance with the FADP.

Affected Users will be informed where required by law or where the information is necessary to reduce the risk.

15. Changes to this policy

  1. We will publish the updated policy on the Platform.
  2. We will notify Users by email in case of material changes.
  3. We will indicate the last update date.
