Your data stays on your computer.It leaves only when you use AI.
AiiB keeps your documents off any server of ours. This page explains where it runs, what it stores, and what leaves your computer, using only facts we have verified.
Overview
What stays on your computer, and what leaves
The dashed frame is your computer. Your documents live in the database inside it. Only two lines go out: when you use AI, and store purchases and updates. There is no line to a server of ours.
Requirements
Where it runs
- Mac
- macOS 13 or later, Apple silicon and Intel. Distributed through the Mac App Store
- Windows
- Windows 10 (1809 or later) / Windows 11, 64-bit. Distributed through the Microsoft Store (MSIX, signed by the Store). Direct download later
- PowerPoint add-in (web)
- PowerPoint in Microsoft 365 on Windows, Mac and the web. PowerPointApi 1.5 or later
- PowerPoint add-in (.ppam)
- Desktop PowerPoint on Windows. Bundled with AiiB for Windows
- Network
- Needed only for AI features and subscription purchases. Everything else works offline
- Languages
- App UI in Japanese, English and Chinese (Simplified). Decks in Japanese, English, Chinese, Korean and German
Data
Where data lives
Decks, notes, documents, exams, projects and settings are stored as one database file (SQLite) in the app’s own area on your computer. We cannot access this file.
- Not in the cloud
There is no server of ours and no sync service.
- Export and import
Export to a file from Settings › Database and import it on another Mac or Windows PC.
- Deletion
Deleting the app deletes the data on your computer. Export first anything you want to keep.
- Backups
Backing up your computer (Time Machine and so on) and keeping exported files are up to you.
- Images
Pasted images are compressed inside the app (1600 px long edge) and never sent anywhere.
- Standard formats
PowerPoint, PDF, Word, Markdown, LaTeX, PNG/SVG and deck data (JSON). No lock-in.
Network
What leaves your computer
AiiB talks to the outside only in these cases. The matrix below shows where each kind of data goes.
| Your computer | AI provider | Us | Apple / Microsoft | |
|---|---|---|---|---|
| Document and note content | ●stored | ▲only what you send to AI | — | — |
| Redacted words | ●original kept | —sent as tokens | — | — |
| API keys | ●credential store | ▲to authenticate with that provider | — | — |
| Exported files | ●where you save them | — | — | — |
| Purchases and payment | — | — | ▲aggregated, not identifying | ●handled by the store |
| Usage, crashes, ad IDs | —not collected | — | — | — |
- When you use AI
- The content you choose is sent directly to the AI provider you set up, with your own API key, over HTTPS. Never through a server of ours
- Subscriptions
- Handled by Apple (App Store) or Microsoft (Microsoft Store). We never receive your name, payment details, Apple ID or Microsoft account
- Updates
- Delivered through each store’s update mechanism
- Anything else
- Nothing. No analytics, no ads, no crash reporting
AI
AI and your data
AI is optional. Templates, editing, export, notes, documents and exams all work without it. When you do ask AI, this is what happens; the gate inside AiiB replaces redactions and checks the scope.
- Your key, direct
Content goes straight to the provider you chose: Anthropic, OpenAI, Google and others. The app never charges for AI.
- Provider terms apply
What you send is governed by each provider’s terms and privacy policy. Decide before sending anything sensitive.
- Redactions stay hidden
When AI edits slides, redacted words are replaced with tokens before sending and restored before saving. Anything not redacted is sent.
- Scope is enforced
Ask about “this slide” and no other slide is written. Writes outside the scope are refused in code.
- Nothing lands until you accept
Deck-wide changes stay proposals until you compare and accept. A single-slide change undoes in one step.
- Local models
The directly distributed version can connect to a model running on your own computer. Support in the App Store version comes in a later update.
App
How the app is protected
Protection is layered. If an outer layer fails, the inner layers still hold.
- Sandbox (Mac App Store)
Runs in the macOS sandbox with six entitlements only: read/write files you choose, read/write Downloads, outgoing network (AI providers), a local listener (the helper below), printing (PDF export), and the sandbox itself.
- The helper stays on your computer
A helper process for export and AI editing runs in the same sandbox and listens only on 127.0.0.1. It cannot be reached from other computers, and it checks who is calling.
- No launching other programs
The Mac App Store version does not include features that launch other programs on your computer.
- Keys
API keys are stored in the macOS Keychain or Windows Credential Manager and never leave the app.
- Sanitized input
Figures (SVG) and document HTML are stripped of dangerous parts (scripts, event attributes, external URLs and so on) before they are drawn.
- Signing and distribution
Signed by Apple on Mac and by the Microsoft Store on Windows. Only builds that pass store review reach you.
PowerPoint
PowerPoint add-in
- The web add-in works on its own
The alignment tools run entirely inside PowerPoint. Nothing is sent to an outside server or to AiiB. It is hosted at https://atobhundred.com/aib/addin/.
- Only the shapes you select
The web add-in reads and writes the position and size of the shapes you select.
- The .ppam talks only to AiiB on the same PC
“Insert from AiiB” and “Send to AiiB” in the Windows .ppam exchange data only with AiiB open on the same PC.
Privacy
