Privacy Policy

Effective date: 17 June 2026

dotMux is a native SSH client for iPhone and iPad. This policy explains, in plain language, what the app does with your data. The short version: the dotMux app collects nothing about you. There are no accounts, no ads, and no servers run by us, and the app contains no analytics or tracking. (This website uses privacy-first, cookieless analytics — see This website below.) The rest of this page just spells that out.

What the dotMux app collects

Nothing.

We don't run a backend. The app has no sign-up and no login. The app contains no analytics, tracking, advertising, or crash-reporting tools. We never see who you are, which servers you connect to, what you type, or that you use the app at all.

The data the app handles, and where it stays

To do its job, dotMux stores some information on your device only:

• SSH credentials — the keys and passwords you add for your servers. These live in the iOS Keychain and Secure Enclave and never leave your device. They are bound to that specific device (and are erased if you remove your device passcode), and are never synced to iCloud or anywhere else.
  • Secure-Enclave keys are generated on-device, can't be exported, and only ever sign inside the Secure Enclave.
  • Imported keys are stored in the Keychain and unlocked with Face ID / Touch ID; saved passwords are stored in the Keychain and unlocked with Face ID / Touch ID or your device passcode.
• Your host settings — server addresses, ports, usernames, and your per-host preferences, so you don't have to re-enter them. These stay on your device.
• Diagnostics (only if you turn them on) — an optional, on-device log to help you debug a failed connection. It records the connection process (the commands used to start your tmux session, session names, and a short sample of what the server prints while connecting, such as login banners or error messages). It never records your keystrokes or the contents of your terminal session. It stays on your device unless you choose to share it yourself via the iOS share sheet.

None of this is transmitted to us. We have no way to read any of it.

How connections work

When you connect to a server, dotMux opens an SSH connection directly from your device to the server you specified. Your traffic goes to your servers and nowhere else. It does not pass through us, and we operate no intermediary or relay.

Third parties

The only third party involved is Apple, and only for purchases.

dotMux offers a one-time purchase to save more than one server. Payment is handled entirely by Apple through the App Store using StoreKit — we never see or receive your payment details. Apple gives us only the standard aggregate sales information every developer receives (such as units sold), which does not identify you. Apple's handling of that transaction is covered by Apple's Privacy Policy.

This website

Everything above describes the dotMux app. This website, dotmux.dotpt.com, uses Cloudflare Web Analytics — a privacy-first, cookieless analytics tool — to record anonymous, aggregate metrics such as page views, referrers, country, and page-load performance, so we can see what's useful and improve the site. It sets no cookies, stores nothing on your device, builds no profile of you, and cannot identify you. Cloudflare processes this data on our behalf as a data processor. Because there are no tracking cookies and nothing is stored on your device, there is no cookie consent banner — there is nothing to consent to.

Children

dotMux is rated 4+ and is suitable for all ages. Because the app collects no data from anyone, it collects no data from children.

Changes to this policy

If this policy changes, we'll update this page and revise the effective date above. Since dotMux has no way to contact you, this page is the source of truth — check back here for the current version.
