Terms of Service

Last updated: March 26, 2026

These terms govern your use of Marginalia, a social reading application operated by Digitalheads (digitalheads.pl). By creating an account, you agree to these terms and our Privacy Policy.

What Marginalia is

Marginalia is a social reading app for DRM-free EPUB files. You upload your own legally obtained books, read them in the browser or on your device, highlight passages, write notes, and optionally share your annotations with other users.

Your account

Your content

EPUB files
You must have the legal right to the books you upload. Marginalia does not verify copyright ownership and is not responsible for the legality of uploaded files. You retain full ownership of your files.
Highlights and annotations
You own your highlights and notes. By setting a highlight to "public," you grant Marginalia a limited license to display it to other users within the app (in feeds, profiles, and in-book social highlights). You can revoke this at any time by setting highlights back to private or deleting them.
Profile information
You control what is visible on your public profile. You can make your reading activity private at any time through your privacy settings.

Acceptable use

You agree not to:

Copyright and takedown requests

Marginalia respects copyright. If you believe that content on our platform infringes your rights, please send a takedown notice to legal@digitalheads.pl including:

  • Identification of the copyrighted work
  • Identification of the infringing material and its location on Marginalia
  • Your contact information and a statement that you are authorized to act on behalf of the rights holder

We will review valid requests promptly. Accounts with repeated valid copyright complaints may be terminated.

Service availability

Marginalia is provided "as is" without guarantees of uptime or availability. We make our best effort to keep the service running reliably, but we do not offer a service-level agreement.

We may modify, suspend, or discontinue part or all of the service at any time. When possible, we will provide reasonable advance notice of significant changes.

Limitation of liability

To the fullest extent permitted by applicable law, Marginalia and Digitalheads are not liable for:

Termination

Governing law

These terms are governed by the laws of Poland. Any disputes will be subject to the jurisdiction of the courts in Poland. If you are a consumer in the EU, this does not affect your rights under mandatory consumer protection laws of your country of residence.

Changes to these terms

We may update these terms from time to time. When we make significant changes, we will notify you through the app or by email. Continued use of Marginalia after the notice period constitutes acceptance of the updated terms.
