Mightora full logoPrompt Builder

PRIVACY BY DESIGN

Your prompt is built in your browser

No account, no AI API connection and no prompt submission endpoint.

What the tool does with your information

The Prompt Builder composes text on your device using local JavaScript. Prompt fields and pasted material are not sent to Mightora or to any AI provider by this application. You choose what to copy and where to paste it.

What is saved

Prompt fields are not automatically saved. When you explicitly save a custom role, it is stored in your browser’s localStorage, under the key mightora-prompts-custom-profiles-v1. You can delete saved profiles in the builder or clear site data in your browser. There is no cloud sync or recovery.

Online network resources

The public site requests shared Mightora styles, components and a YAML footer feed using jsDelivr, and may request the official logo or badge imagery from GitHub and Shields.io. These third-party hosts receive ordinary HTTP requests; their own policies apply. The app itself makes no requests to a language-model API and does not add analytics or tracking pixels.

How to inspect network activity

  1. Press F12 to open your browser’s Developer Tools.
  2. Select the Network panel and enable Preserve log.
  3. Reload the page and examine all requests and destinations.

The on-page Performance Resource Timing summary can omit requests, so it is not a substitute for the browser Network panel or independent testing.

The offline edition

Download the single offline HTML file or offline ZIP. Open the HTML file directly in your browser; it embeds the application code, styles and logo and makes no automatic internet requests. Offline pages do not include the live shared footer feed or remote badges.

Important caution

Do not paste confidential, personal or sensitive material into an external AI assistant unless its use is authorised. This site cannot control what happens after you copy a prompt to another service.
