This Privacy Policy explains how we collect, use, and protect information when you use the Application. By using ElectricalSoft, you agree to the practices described in this document and to the Application’s Terms of Use.

1. Data Controller

The data controller responsible for the processing of your personal data is the developer of ElectricalSoft. For any questions related to privacy, you may contact us at [email protected].

We may collect the following categories of information:

  • Registration data: username, email address, and password when creating an account.
  • Usage data: calculations you create within the application.
  • Technical data: browser type, operating system, and session identifiers. IP addresses may be recorded in access logs by infrastructure providers (hosting and CDN), but are not directly stored by the application.
  • Voluntary contribution data: when you choose to make a voluntary contribution to the project, the necessary payment data is processed securely by our external payment provider (Stripe). We do not store card data. Such contributions are voluntary and do not constitute the purchase of a service, as established in the Terms of Use.
  • Communication data: messages you send to our support team.

  • Application improvement: to analyze usage patterns and improve the software (legal basis: legitimate interest).
  • Communications: to send notices related to the Application (legal basis: legitimate interest).
  • Legal compliance: to comply with applicable laws and regulations (legal basis: legal obligation).

4. Data Retention

We retain your personal data while your account remains active or as necessary for the operation of the Application. Account data is deleted within 30 days of a deletion request or termination of access in accordance with the Terms of Use, unless retention is required by law. Aggregated or anonymized data (which does not identify you) may be retained indefinitely for statistical and software improvement purposes.

5. Data Sharing with Third Parties

We do not sell your personal data. We may share data with:

  • Stripe: for processing voluntary contributions. Stripe Privacy Policy.

  • Legal authorities: when required by applicable law or a court order.

6. International Data Transfers

Your data may be processed in countries other than your own. In such cases, we ensure that appropriate safeguards are in place (for example, standard contractual clauses approved by the European Commission).

7. Cookies

ElectricalSoft uses cookies and similar technologies to maintain sessions and store user preferences. For a detailed list of cookies used, their purpose, duration, and how to manage them, please read our Cookie Policy.

8. Security

We implement reasonable security measures, including encrypted connections (HTTPS), hashed passwords, and access controls. No method of transmission over the internet is 100% secure; while we cannot guarantee absolute security, we are committed to addressing any known breach promptly.
