This site
maciejbula.dev runs no analytics, no third-party trackers, and sets no cookies. Your light/dark theme preference is saved in your browser's localStorage and never leaves your device. The site is hosted on Cloudflare Pages, which may retain standard server logs (IP, request path, timestamp) for abuse prevention and routing — see Cloudflare's privacy policy for specifics.
The apps
The default for everything I make: nothing leaves your device unless explicitly stated for a specific app. No telemetry, no usage analytics, no event tracking. If an app talks to a network at all (e.g. downloading an AI model on first run), that's described on the app's page.
Crash reports
No app currently sends crash reports. If a future release of any app adds them, they will be opt-in (off by default), disclosed in the per-app section below, and will name the service handling them.
Payments
iOS apps are sold via the App Store under Apple's policy; I only see aggregate sales reports. Direct macOS sales are handled by Creem under their privacy policy and terms; I receive only what's needed to deliver the app and meet tax obligations.
Contact
Emails sent to hello@maciejbula.dev are used only to reply. No mailing list, no newsletter.
