Privacy Policy
Effective date: August 20, 2026
This policy covers the ezTerm desktop application and theezterm.zerosandones.us website, both operated by Zeros and Ones LLC ("we", "us"). The short version: the ezTerm application collects no personal data. It has no telemetry, no analytics, no advertising, and no user accounts. We never see your hostnames, usernames, passwords, keys, or terminal traffic.
Data stored on your device
ezTerm stores its data in a local SQLite database on your computer. This includes your saved sessions and folders (hostnames, ports, usernames), known-host fingerprints, application settings, and — if you use the credential vault — your saved credentials.
Vault credentials are encrypted at rest with ChaCha20-Poly1305 using a key derived from your master password with Argon2id. Your master password is never stored; without it, the vault cannot be decrypted — by you, by us, or by anyone else. Decrypted secrets exist only in memory while in use and are wiped afterwards.
None of this data ever leaves your device, and we have no ability to access it. Uninstalling ezTerm (and removing its data directory) deletes it entirely.
Network connections the app makes
ezTerm connects to the network only in these cases:
- Your SSH / SFTP / SCP sessions. The app connects directly to the servers you configure, at your instruction. This traffic goes between your computer and your servers; it does not pass through, and is not visible to, any service we operate.
- Update checks. ezTerm checks GitHub Releases (
github.com) for new versions and downloads updates from there. Like any web request, GitHub receives your IP address and a user-agent string; we receive nothing. See theGitHub Privacy Statement. - Optional X server download (Windows). If you enable X11 support and choose to install the bundled X server, ezTerm downloads VcXsrv from SourceForge (
sourceforge.net), which is governed by theSlashdot Media privacy policy. This happens only when you request it.
Website analytics
This website (not the app) uses Google Analytics 4 to count page views, configured with IP anonymization and with Google signals and ad-personalization disabled. We use it only to understand aggregate site traffic. See theGoogle Privacy Policy. The ezTerm application itself contains no analytics of any kind.
Children's privacy
ezTerm does not collect personal data from anyone, including children.
Changes to this policy
If we change this policy, we will update this page and the effective date above. Because the site and the app are open source, the full history of this document is available in the public repository.
