Privacy Policy
Last updated: October 30, 2026
Overview
Flowdeck (“we”, “our”, or “us”) is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use the Flowdeck CLI and Flowdeck Studio macOS app.
The short version
Flowdeck development work runs locally on your Mac. Flowdeck Studio and the Flowdeck CLI use the same PostHog product analytics, identified only by a one-way hash, and you can turn it off in either. We do not send source code, project data, build output, names, email addresses, license keys, license IDs, or license statuses to PostHog. Our website uses anonymous Google Analytics and PostHog product analytics with privacy-masked session replay. We collect your name and email at purchase, and we never sell your data.
Product Analytics
Flowdeck Studio and the Flowdeck CLI both use PostHog, in the same way, to understand product usage and improve Flowdeck. PostHog receives a salted one-way SHA-256 hash as the distinct ID; a CLI without a license uses a random install identifier instead. The email address and the machine identifier themselves never leave your Mac. Nothing else is attached, so PostHog holds no name, email address, license key, or license ID for you. Beyond the identifier and the plan type, PostHog receives app, CLI, and OS metadata and non-identifying product events such as feature and command usage counts and boolean states. We do not collect or transmit:
Source code, project files, or build output
Build logs, compiler output, or terminal output
Project names, schemes, targets, or file paths
Names, email addresses, license keys, license IDs, or license statuses through PostHog
Crash reports or stack traces
To be precise about what the hashed identifier means: it is pseudonymous, not anonymous. PostHog cannot tell who it belongs to, but we can match it back to an account by hashing a license ourselves, and we can act on a deletion request for that reason. We treat it as personal data accordingly.
You can turn product analytics off at any time, in either product. In Flowdeck Studio, open Settings > Privacy and turn off Share Usage Data; this also turns it off for the CLI on the same Mac. For the CLI on its own, set the environment variable FLOWDECK_ANALYTICS=0.

What We Collect
When you purchase Flowdeck or start a trial, we collect:
Name and email address. Required to create your license and send you purchase confirmation and license information.
We never share, sell, or rent your personal information to third parties. Your data is used solely to manage your license, provide support, and improve the product.
What We Don’t Collect
Flowdeck does not collect:
Your source code or project files
Build logs or error messages
Hardware profiles or device fingerprints beyond the machine identifier used for licensing and the PostHog distinct ID used by the macOS app and the CLI
Local Processing
All Flowdeck build and development operations run locally on your machine. Your source code, project files, and build outputs never leave your computer.
License Validation
When you activate a Flowdeck license, minimal information is exchanged with our license server (powered by Lemon Squeezy) to validate your license key. This includes:
Your license key
A machine identifier (to enforce license activation limits)
Website Analytics
Our website (flowdeck.studio) uses Google Analytics and PostHog to understand how visitors find and use our site. PostHog provides product analytics, performance and error signals, heatmaps, and session replay. This website analytics does not track your use of the Flowdeck software itself. You can opt out using browser extensions or privacy tools.
Website visitors are anonymous. We do not link your website visit to your license, your purchase, or your use of the macOS app.
Privacy-masked session replay. PostHog may record privacy-masked playbacks of website visits. All form inputs are masked, and sensitive query parameters, including license keys, are redacted in the browser before analytics or replay data is sent. Website visitors remain anonymous and are not identified against the macOS app.
Third-Party Services
We use the following third-party services:
Lemon Squeezy. Payment processing and license management. Their privacy policy applies to purchase transactions.
Google Analytics. Website analytics only (not in-app).
PostHog (website). Website analytics and privacy-masked session replay (not in-app).
PostHog (macOS app and CLI). Pseudonymous product analytics in the macOS app and the CLI, identified by a one-way hash, which you can turn off in either. We do not send names, email addresses, license keys, or license IDs to PostHog.
