Privacy
The email, the download, and nothing else.
This page asks for one thing. There is no account, no tracking script here, no cookie, no third-party request of any kind.
What is stored
The email address you type into the download form. That is the whole record: the address, which page it came from, which platform you were on, and when. It is kept in Cloudflare's key-value store, behind a Pages Function on /api/subscribe, and it is used for two things — sending you the download link, and sending release notes when a version ships.
What is not stored
No name, no company, no account, no payment details. No IP address next to your address: a one-way hash of it is kept for sixty seconds so the form cannot be used to flood the endpoint. No user agent, no referrer, no cookie. Nothing here reads anything off your machine.
Never sold, never shared
The address is not sold, rented or given to anyone. It is not used to build a profile and it is not combined with anything else. If an email tool has been wired to the endpoint, that tool receives the address only to send the two kinds of message above. Every message has a one-click unsubscribe.
Deleting it
Ask and it is removed. Open an issue at github.com/alexsofroniev/mqttdeck with the address you used, or reply to any message from it, and the record is deleted — no account to close and nothing kept for reporting.
The installers come from GitHub
The download itself is a file hosted on GitHub Releases, so GitHub sees that request under its own privacy policy. Nothing about that download is reported back to this page.
Inside the app
MQTT Deck is a different story and it says so plainly. It sends anonymous usage analytics and crash reports, on by default, and one switch in Settings turns them off. It never sends a broker address, a topic name, a payload or a credential. Every event and property is listed in the app's own privacy document: docs/PRIVACY.md.
