FAQ
About the tools
Are the tools free?
Yes. The tools are free, need no account and add no watermark to downloaded previews.
Do the tools upload my drafts?
No. Text and local media stay in your browser. If you choose to continue in SimplePost, only the text of your versions is handed over in the link fragment, which browsers do not send to servers. The app keeps it in that browser for up to 24 hours until you import it.
Are the previews identical to the real networks?
They are close approximations drawn by SimplePost's open-source preview renderer, the same one used in the scheduler. Networks change their interfaces, so check critical details in the native app.
