Privacy, security and recovery
Where your data is kept, how it is protected, when anything leaves your PC, and what to do if you lose a PC.
This section explains where your library is kept, how it is protected, when anything leaves your PC, and what to do if a PC or your recovery kit is lost.
The ideas to know first:
- Your library stays on your PC. It isn’t stored on a PromptMason server, and you don’t need an account to use it. Text leaves your PC only when you take an action that sends it somewhere, such as running AI with a cloud provider.
- Its text is encrypted on disk. The key is unlocked by your Windows account, so there is no password to type. Names, tags and folder names stay readable so search works.
- App Lock puts a password on PromptMason’s window. It’s off to start with, and it locks the window only.
- The recovery kit is a spare copy of your keys: one file and a code. You need it only if you lose every PC you use.
Start with Privacy in PromptMason, which lists everything that can leave your PC and the settings that control it. How your data is protected on this PC explains what is and isn’t encrypted. If a PC goes missing, go straight to Lost or stolen PC or kit.

About PromptMason: a Windows desktop app for building AI prompts from reusable blocks. A person writes blocks (reusable pieces of prompt text), builds prompts from them on the Build screen (or keeps a Markdown document, such as a Skill), and copies a prompt into an AI tool, runs it in PromptMason’s own Chat, or lets a connected AI agent use it through PromptMason’s built-in MCP server (the Chrome extension copies prompts on any website). AI assist, Evaluate and Chat use a local model that runs on the person’s PC, or their own AI provider. The guides are also on PromptMason’s Help screen, and Chat can answer “how do I” questions from them. Libraries hold the blocks and prompts; a person can sync their personal library to their other PCs and share team libraries, both through a folder in cloud storage they already have (OneDrive, Google Drive or Dropbox). Everything synced is encrypted and every edit is signed and checked. A recovery kit (a file plus a code) is the spare copy of the person’s keys, for when every PC is lost.

After each step, ask what I see on screen before giving the next one. - Use the exact words on PromptMason’s buttons and screens, as the guide does. - Never ask me for my recovery code, my recovery kit file, a password or my invite line, and never ask me to paste them here. - Start by asking which step I’m on, or what I see now.
