Privacy Policy

Last updated: 22 September 2026

01 Data Controller

Volter is a product of Asenko BV, located at Nieuwstraat 9, 3472 Kortenaken, Belgium. For privacy-related questions, contact us at info@volter.be.

02 What Data We Collect

We only collect personal data that is necessary to provide our service. We do not use third-party analytics services, tracking pixels, or advertising cookies.

Payment & Billing

When you subscribe, Paddle (our payment processor and merchant of record) collects your name, email address, billing address, and payment details. Paddle processes this data as an independent data controller under their own privacy policy.

Account and Access

When you create a Volter account, we store your email address and subscription details with Google Firebase (Authentication and Firestore) to manage your account and your access to the Software. If you sign in with Google, we receive your name and email address from Google.

Your projects

When you save a project, we store it in your account with Google Firebase: the drawing itself (floor plan, single-line diagram and panel schedule) together with the details you enter, such as the name and address of the site, the client name, your installer details and EAN codes, plus small preview images of your plans. That is what lets you open your projects on every device you sign in on. If you set a company logo in the settings, we store it as an image in your account with Google Firebase and place it on the PDFs you export; you remove it in the same place. This content may contain personal data about your clients. For that data you are the controller and Asenko acts as processor, under the terms set out in our terms of use.

Transactional Emails

We use Resend to send you transactional emails such as account invitations, subscription confirmations, and payment notifications. Your email address is shared with Resend for this purpose.

In-App Feedback

When you submit feedback from within the Volter desktop app, we collect your feedback message, feedback type, and optional email address. A screenshot may be included if you choose to attach one. We also collect app metadata such as your app version, platform, view mode, subscription status, and language setting. This data is stored in Google Cloud Firestore and used to improve the Software.

Usage Data

When you are signed in, we store with your account which version of Volter you use, on which platform (web, Mac, Windows, Linux, iPad, iPhone or Android) and on which days you used the app. We use this data to understand how Volter is used, to know when older versions are no longer in use, and to improve the Software. It is stored in Google Cloud Firestore, is not shared with third parties, is automatically deleted after 12 months, and is erased immediately when you delete your account.

Error Reporting

When the Software runs into a technical error, the desktop app, the web app and the tablet app send an error report to Sentry. Such a report contains the error message and the place in the code where it occurred, the app version, the platform and browser, the view mode, the language setting and, if you are logged in, your account identifier (not your email address). It never contains the content of your projects. We use these reports solely to find and fix errors. Sentry stores them on servers in the EU (Frankfurt).

Waitlist Signup

When you sign up for the beta waiting list, we collect your email address and role. This data is stored in Google Cloud Firestore.

Webhook Event Logs

We log subscription lifecycle events (e.g. subscription created, canceled, payment failed) in Google Cloud Firestore for customer support purposes. These logs contain your email address, subscription identifiers, and event details.

Server Logs

Our website is hosted on Google Cloud (Firebase Hosting). Standard server logs including your IP address and user agent are collected automatically.

Cookie

We use a single functional cookie (__session) to remember your language preference. This cookie does not track you and no consent is required.

03 Legal Basis

Payment processing, account management, storing and syncing your projects, and transactional emails are necessary to perform our agreement with you (GDPR art. 6(1)(b)).

Server logs and webhook event logs are processed based on our legitimate interest in operating our service and providing customer support (GDPR Art. 6(1)(f)). Error reports are processed on the same basis: without them we cannot find and fix errors in the Software.

Waitlist signup is processed based on your consent (GDPR Art. 6(1)(a)).

04 Third-Party Processors

We share your personal data with the following service providers:

  • Paddle (UK/EU) - payment processing and merchant of record
  • Resend (US) - transactional emails
  • Google Cloud / Firebase (EU) - website hosting, accounts and storage of your projects
  • Sentry, Functional Software Inc. (servers in the EU, Frankfurt) - error reporting

05 International Data Transfers

Our processor Resend is located in the United States. This transfer is protected by the EU-US Data Privacy Framework and/or standard contractual clauses (SCCs). Google Cloud stores your data in the EU. Sentry processes error reports on servers in the EU (Frankfurt); support by Sentry may take place from the United States, protected by the EU-US Data Privacy Framework.
