Privacy Notice

Last updated on October 8, 2026.

This notice explains what personal data the viberglass.io website collects, why, who handles it for us, how long it is kept and what your rights are. We collect as little as we can: anonymous visit statistics, the email address you give us when you follow the project, and the messages you send through the contact form.

1. Who we are

The website and the Viberglass project are run by Ilities.dev B.V., registered with the Dutch Chamber of Commerce (KVK) under number 90831683, at Broerenstraat 45-41, 6811 EB Arnhem, the Netherlands. Ilities.dev B.V. is the controller of the personal data described here. You can reach us about privacy at privacy@viberglass.io.

2. What this notice covers

This notice covers the viberglass.io website, including the documentation under viberglass.io/docs. Viberglass itself is open-source software that you install and run on your own infrastructure. We don't host it for you, there is no Viberglass Cloud, and an installation you run doesn't send us your code, tasks or usage data. Whoever operates a Viberglass installation is responsible for the data in it.

3. What we collect and why

3.1. Visit statistics

We use Plausible Analytics to count visits. The Plausible script is served from our own domain and passes its data on to Plausible. For each page view it records the page address, the referring site, your browser, operating system and device type, and the country, region and city derived from your IP address. We also count a few clicks, such as on the View on GitHub button, the links from the home page to the documentation, the newsletter sign-up button and the demo video.

Plausible doesn't use cookies and doesn't store your IP address. To count unique visitors it combines your IP address and browser details with a random value that changes every day and keeps only the resulting hash, so you can't be recognised across days or across websites. We only see totals, never individual visitors. We use this to learn which pages are useful, which is our legitimate interest.

3.2. Following the project

When you enter your email address in the "Follow the project" form, we receive it as an email in our mailbox. We use it only to send occasional release notes and news about Viberglass. We don't use a mailing list service and we don't share the address with anyone. We rely on your consent, which you can withdraw at any time by replying to one of our emails or writing to privacy@viberglass.io.

3.3. Contact form

When you use the contact form, we receive your name, email address and message as an email in our mailbox, and use them only to read and answer your message. We rely on our legitimate interest in answering the people who contact us.

3.4. Server logs

The servers that deliver the site and handle the forms see your IP address, browser details and the pages you request, and may record them in technical logs. These are used to run the site, keep it secure and stop abuse. The newsletter form also keeps your IP address briefly in memory to limit how often it can be submitted.

3.5. Fonts

The site loads some of its fonts from Google Fonts. Your browser downloads them directly from Google, so Google receives your IP address and browser details when you open a page. Google doesn't receive anything you type into the site.

3.6. Cookies and local storage

The website doesn't set cookies. If you pick a tone with the tone selector, your choice is saved in your browser's local storage so the site remembers it. It stays on your device and isn't sent to us.

4. Who handles the data for us

  • Amazon Web Services hosts the website and runs the newsletter and contact form handlers, and Amazon Simple Email Service delivers the resulting emails to us. The form handlers run in the AWS Europe (Ireland) region.
  • Plausible Insights OÜ, based in Estonia, processes the visit statistics described in section 3.1 on servers in the EU.
  • Porkbun forwards email sent to viberglass.io addresses to our mailbox, and Google stores the newsletter sign-ups and contact messages we receive there in Gmail.
  • Google provides the fonts described in section 3.5.

We don't sell personal data, use it for advertising, or share it with anyone else unless the law requires us to.

5. How long we keep it

  • Visit statistics are kept only as totals, for as long as we use Plausible.
  • Your email address for project updates is kept until you unsubscribe or ask us to delete it.
  • Contact form messages are kept until we've dealt with your message and deleted within two years, sooner if you ask.
  • Technical logs are kept only as long as needed to run and secure the site.

6. Transfers outside the EU

We keep the data we handle in the EU where we can. Google, for fonts and our mailbox, Porkbun when it forwards our email, and Amazon Web Services when it serves the website through its global network may process your data outside the European Economic Area. Where that happens, they rely on the EU-U.S. Data Privacy Framework or the European Commission's standard contractual clauses.

7. Your rights

Under the GDPR you can ask us for a copy of the personal data we hold about you, ask us to correct or delete it, ask us to restrict how we use it, object to how we use it, and ask for it in a portable format. Where we rely on your consent, you can withdraw it at any time. Write to privacy@viberglass.io. It's free, and we answer within one month.

If you think we handle your data wrongly, you can complain to the Dutch Data Protection Authority (Autoriteit Persoonsgegevens) or to the data protection authority where you live.

8. Links to other websites

The site links to other websites, such as GitHub. Their own privacy notices apply when you visit them.

9. Changes to this notice

If what the website collects changes, we update this notice and the date at the top of the page.
