Privacy
Posteçî sends your requests, and nothing else.
Posteçî has no account, no analytics and no crash reporting. It doesn't phone home, check for updates in the background or collect anything about how you use it.
The only network traffic it creates is what you ask for: the requests in your files, and the OAuth token requests your @auth lines describe.
Workspaces are folders on your Mac that you choose; the app is sandboxed and can't read anything else. Values written with save go to environment.local.stamp in the workspace, which is kept out of git when the workspace is a repository. Cookies are kept per workspace window and can be cleared from Environment › Cookies….
The App Store privacy label for Posteçî is Data Not Collected. Questions are welcome at privacy@siamand.cc.
