Your brain dump stays yours

Your notes are private until you share them

Every note starts visible only to you. Nothing is public unless you create a share link for a note or folder.

Anyone with a share link can open it, so share it only with people you trust. You can turn a link off any time.

Where your notes live

Without an account, notes stay on your device and sync through your own iCloud across iPhone, iPad, Mac and Vision Pro.

With a BrainDump account, notes sync through our servers instead, which also lets you use the web app and Windows. You don't need an account to start writing.

The apps work offline. Changes sync when you're back online.

What AI sees, and when

AI only runs when you use an AI feature, like Ask, rewriting a page or Untangle. Nothing is read in the background.

When you do, the text you picked (or, for folder suggestions, folder names and a short excerpt of each note) is sent to our servers and processed by Google Gemini through Google Cloud Vertex AI, which acts as our service provider, to return a result.

Ask can change notes for you, but every change shows first and waits for your OK. Notes it removes go to the Trash, never deleted for good.

Your notes don't train AI models

We do not use your content to train AI models. Your brain dumps are yours, not training data.

Claude and ChatGPT, only if you connect them

You can connect Claude or ChatGPT to search your notes and add to them. It's off until you connect it, and you can disconnect any time.

A connected assistant can never edit or delete what's already in a note. Notes it reads are then handled by that assistant's provider under its own privacy policy.

Take your notes with you, or delete everything

Back up everything to one file from the app or the web, and export notes as PDF, RTF, HTML or text (plus Markdown and Word with Focus).

Deleting your account removes everything saved online. Notes on your device stay, so you can keep them.

Payments go through Apple

Plans are bought inside the app. Apple handles and stores the payment details, and we never see your card.
