Privacy Policy

Last Updated: September 24, 2026 (version 2)

This Privacy Policy explains how Martijn Courteaux (“I,” “me,” or “my”) collects, uses, and protects your information when you visit my website or use the SilverNode desktop application (“the Software”).

The controller responsible for your personal data is:

Martijn Courteaux, sole proprietor
Tramstraat 28, 9052 Zwijnaarde, Belgium
Enterprise number (KBO): 1033.151.354
Email: support@silvernode.io

I believe in data minimization: I only collect what I need to run my business, validate your license, and provide support.

1. Information I Collect and How I Use It

A. When you visit my website or download SilverNode

If you consent through the cookie banner, I use Google Analytics to understand how visitors interact with my website. Google Analytics uses cookies to collect usage data (such as pages visited and time spent on the site). This data is pseudonymous: your browser is assigned a random identifier, but I cannot see who you are. I only look at this data in aggregate reports to improve my website, and I do not try to identify you. For more information, please refer to the Cookie Policy.

When you visit my website, my hosting provider processes your IP address and technical details of your request (such as your browser type) in order to deliver the website to you.

When you download SilverNode, my download server records the date and time, your IP address, and the name of the downloaded file. I use this to compile download statistics and to detect and prevent abuse, such as automated mass downloading.

B. When you purchase a license

I use Sold through Link, LLC f/k/a Lemon Squeezy LLC (“Lemon Squeezy”) as my payment provider and Merchant of Record. When you make a purchase, your transaction is processed directly by them on their hosted checkout page. Lemon Squeezy uses cookies to process payments and manages all of your billing data securely. My website does not load anything from Lemon Squeezy until you click the “Buy License” or “Upgrade License” button. When you do, Lemon Squeezy’s checkout script is loaded and their checkout opens in a pop-up on this page, effectively bringing you onto Lemon Squeezy’s website. As Merchant of Record, Lemon Squeezy sells the license to you and processes your payment and billing data as an independent controller, under its own privacy policy, not on my behalf. I recommend consulting Lemon Squeezy’s privacy policy (which includes their cookie policy).

I do not see, collect, or store your credit card or payment details. From Lemon Squeezy, I only receive and store:

• Your full name
• Your email address
• Your country of residence
• Your purchase history and license keys

I use this information solely to deliver your software license, provide customer support, track your purchase status, and send you service emails about the Software you purchased (see section E below).

C. When you use SilverNode

SilverNode is designed to respect your privacy. It does not track your workflow, collect your photos, or send telemetry data.

• License Activation and Validation: To enforce the 5-device limit per license, the Software contacts my licensing server when you activate your license, and periodically afterwards to validate it. It sends:
  • your license key;
  • a hashed device identifier, derived from an identifier of your device (such as the MAC address of its network adapter, or the machine ID of your operating system), which lets me distinguish your devices without receiving the original identifier;
  • the device name you enter when activating the license (only upon activation).
  My licensing server passes this information on to Lemon Squeezy, which keeps track of the activations of your license. My licensing server does not store it. The hashed device identifier does not reveal who you are on its own, but because it is linked to your license key, it is still considered personal data.
• Configuration Files: SilverNode stores configuration files locally on your system to maintain your settings across sessions. These files are never sent to me or shared.
• Crash Dumps and Logs: If SilverNode crashes, it may produce a local crash dump or log file on your machine. These files are never sent to me automatically. It is entirely your choice whether to manually share these files with me to help fix bugs.

D. When you subscribe to my newsletter

You can subscribe to my newsletter through the sign-up form on my website, or through the link provided after your purchase. After signing up, you receive an email with a link to confirm your subscription; you are only subscribed once you confirm. If you subscribed to my earlier mailing list, from before SilverNode was released, you are also part of this newsletter. I store your email address, together with a record of when and how you subscribed and confirmed your subscription. I use it only to send you news about SilverNode, such as new releases and features.

Purchasing a license does not subscribe you to the newsletter. You will only receive it if you sign up yourself.

E. Service emails

As a customer, you may receive emails about the Software you purchased, such as notices about available updates included in your license, security issues, or changes to your license or to these policies. These emails do not contain advertising. To send them, the name and email address I receive from Lemon Squeezy are automatically added to my email provider, Brevo.

2. Legal Basis for Processing

Under the GDPR, I may only process your personal data when there is a legal basis for it. I rely on the following:

• Delivering and validating your license: Processing your name, email address, country, purchase history, license keys, hashed device identifiers, and device names is necessary to perform our contract (Art. 6(1)(b) GDPR), including enforcing the 5-device limit set out in the Terms of Service. Without this data, I cannot deliver or validate your license.
• Service emails: Informing you about updates, security issues, and changes relevant to your license is part of performing our contract (Art. 6(1)(b) GDPR).
• Customer support: When you contact me about your license or the Software, I process the information you send me to perform our contract (Art. 6(1)(b) GDPR). For other questions, I rely on my legitimate interest in answering them (Art. 6(1)(f) GDPR).
• Crash reports and log files you choose to share: My legitimate interest in finding and fixing bugs in the Software (Art. 6(1)(f) GDPR).
• Tax and accounting records: Complying with my legal obligations under Belgian tax and accounting law (Art. 6(1)(c) GDPR).
• Website hosting and download logs: My legitimate interest in delivering my website and the Software to you, compiling download statistics, and protecting my servers against abuse (Art. 6(1)(f) GDPR).
• Website analytics (Google Analytics): Your consent (Art. 6(1)(a) GDPR), which you give through the cookie banner. Google Analytics cookies are not placed unless you accept them.
• Newsletter: Your consent (Art. 6(1)(a) GDPR), which you give by subscribing. You can unsubscribe at any time using the link in every newsletter.

Where I rely on your consent, you can withdraw it at any time. This does not affect the lawfulness of processing carried out before you withdrew it. Where I rely on my legitimate interest, you have the right to object to that processing (see Section 6).

3. Third-Party Services

To operate my software and business, I rely on the following third-party services. Where they process personal data on my behalf, I have a data processing agreement with them.

• Lemon Squeezy: Acts as my Merchant of Record and manages your subscriptions. You can view their privacy policy at lemonsqueezy.com/privacy. You can manage your purchases and subscriptions at any time using the Lemon Squeezy Customer Portal.
• Google Analytics: Google Ireland Limited provides basic website traffic analysis, only if you consent to it.
• Netlify: Netlify, Inc., based in the United States, hosts my website.
• DigitalOcean: DigitalOcean, LLC, based in the United States, hosts my licensing and download server in a data center in Amsterdam, the Netherlands.
• Brevo: Sendinblue SAS, based in France, stores the email addresses of my customers and newsletter subscribers, and sends my service emails and newsletters on my behalf. You can view their privacy policy at brevo.com/legal/privacypolicy.
• Zoho: Zoho Corporation B.V., based in the Netherlands, hosts my email, including the messages you send to support@silvernode.io.
• Discord: If you choose to join my community Discord server to report bugs, share logs, screenshots, or screen recordings, any information you share voluntarily is governed by Discord’s Privacy Policy.

Transfers outside the European Union: Some of these companies (Lemon Squeezy, Google, Netlify, DigitalOcean, and Discord) are based in the United States, so your personal data may be transferred to or accessed from there. Such transfers are protected by the EU-U.S. Data Privacy Framework for companies certified under it, and otherwise by the Standard Contractual Clauses approved by the European Commission (Art. 46 GDPR).

4. Data Retention

• Customer & License Data: I keep the customer and license data provided to me by Lemon Squeezy for as long as your license exists, because I need it to validate your license. For a perpetual license, this means for as long as you may use the Software, unless you ask me to delete it (see Section 6). Records I am required to keep under Belgian tax and accounting law are kept for the legally required period (currently 10 years).
• Service Emails: Your details in Brevo for service emails are kept as long as your customer data.
• Support Emails: I keep your support emails as long as needed to handle your request and any follow-up questions, and delete them at the latest 2 years after our last contact.
• Download Logs: Download logs containing IP addresses are deleted after 90 days. The download statistics I derive from them contain no personal data and may be kept indefinitely.
• Google Analytics: Google Analytics data is automatically deleted after 2 months.
• Newsletter: I keep your email address on the newsletter until you unsubscribe. I keep the record of your subscription for as long as needed to prove that you consented.
• Crash Reports and Logs: If you voluntarily send me a crash report or log file, I keep it only temporarily to investigate and resolve the issue. Once the bug is fixed, the file is deleted from my systems.

5. Data Security

I take reasonable measures to protect your information from unauthorized access, use, or disclosure. However, no method of transmission over the internet or method of electronic storage is 100% secure. While I strive to protect your information, I cannot guarantee its absolute security.

6. Your Privacy Rights

Under the General Data Protection Regulation (GDPR), you have the following rights regarding your personal data:

• Right of Access: You can ask me whether I process your personal data, and request a copy of it. You can also view your purchase history and subscriptions yourself at any time via the Lemon Squeezy Customer Portal.
• Right to Rectification: You can ask me to correct personal data that is inaccurate or incomplete.
• Right to Erasure: You can ask me to delete your personal data. I keep records that I am legally required to keep (such as tax and accounting records) for the legally required period. Because your license key and email address are needed to validate your license, deleting them means I can no longer validate your license, and the Software can no longer be activated. Lemon Squeezy keeps its own records of your purchase as Merchant of Record; to have those deleted, please contact Lemon Squeezy.
• Right to Restriction of Processing: In certain cases, for example while I verify a correction you requested, you can ask me to temporarily limit how I use your personal data.
• Right to Data Portability: You can ask me to provide the personal data you gave me in a structured, commonly used, machine-readable format, or to transmit it to another party.
• Right to Object: Where I process your personal data based on my legitimate interest (see Section 2), you can object to that processing at any time, for reasons related to your particular situation. I will then stop, unless I have compelling legitimate grounds that override your interests, or need the data to establish, exercise, or defend legal claims.
• Right to Withdraw Consent: Where I rely on your consent, you can withdraw it at any time. For the newsletter, click the “Unsubscribe” link at the bottom of any newsletter. For Google Analytics, click “Cookie Settings” at the bottom of my website’s home page and choose “Deny”. Unsubscribing from the newsletter does not stop service emails about your license; if you also want to stop receiving those, contact me.
• Deletion of Crash Reports: If you have shared crash reports, screenshots, or log files with me via Discord or email, you can contact me at any time to request their immediate deletion.

I do not make decisions about you based solely on automated processing, and I do not profile you.

How to exercise your rights: Send an email to support@silvernode.io. This is free of charge. I will respond within one month; for complex requests, this may be extended by up to two more months, in which case I will let you know. To protect your data, I may ask you to confirm your identity, for example by writing from the email address associated with your license.

Right to Lodge a Complaint (Art. 77 GDPR): You have the right to lodge a complaint with a data protection supervisory authority, in particular in the EU country where you live or work, or where you believe the violation took place. In Belgium, this is the Data Protection Authority (Gegevensbeschermingsautoriteit / Autorité de protection des données), Drukpersstraat 35, 1000 Brussels (dataprotectionauthority.be).
Before filing a complaint, I encourage you to contact me at support@silvernode.io to find a quick solution to your complaint.

7. Changes to This Policy

I may update this Privacy Policy, for example when I start using a new service or when the law changes. The date and version at the top of this page show when it was last changed. If I make significant changes, I will inform you, for example by email or on my website.
