Privacy Policy

Last updated: April 11, 2026

SilverBullet+ is built by Zef Hemel (“we”, “us”). This policy explains what data we collect, why, and how we handle it.

The short version

Your notes never leave your machine unless you explicitly set up sync. We collect minimal analytics on the website and app update checks. We don’t sell data, we don’t track you across the web, and we don’t want to know what’s in your notes.

Your notes and data

SilverBullet+ stores your notes as plain files on your local filesystem. We have no access to your notes, files, or any content you create. Your data stays on your machine.

If you choose to enable sync with a SilverBullet server, your notes are transmitted between your device and the server you configure. We do not operate that server. Sync credentials are stored in your operating system’s native keyring.

Website analytics

When you visit our website, we collect:

  • Page visits — which pages are viewed and referring URLs
  • Download clicks — which platform downloads are clicked
  • Session identifiers — randomly generated per browser session, not tied to any personal information

We do not use third-party analytics services. We do not use cookies for tracking. We do not collect IP addresses, names, email addresses, or any personally identifiable information through the website.

App update checks

When SilverBullet+ checks for updates, it contacts our update server.

These requests contain:

  • Your current app version
  • Your operating system and architecture
  • Your update channel preference (stable or edge)

No personally identifiable information is transmitted during update checks.

Third-party services

  • Cloudflare — Our website is served through Cloudflare. Cloudflare may process connection metadata as described in their privacy policy.

Data retention

Website analytics data is retained for up to 90 days and then automatically deleted. We do not build long-term profiles of visitors.

Your rights

Since we collect minimal data and none of it is personally identifiable, there is typically nothing to request deletion of. If you have concerns, contact us and we’ll address them.

Changes to this policy

We may update this policy from time to time. Changes will be reflected by updating the date at the top of this page.
