Acorn 隱私權政策

最後更新：2026 年 10 月 11 日

Acorn 沒有伺服器，也不用註冊 Acorn 帳號。你記的東西存在你自己的 iCloud 或 Google 雲端硬碟，開發者看不到，也沒有收到任何一筆。

你記的東西放在哪

想法、任務、收藏、錄音、專案名稱和常用詞，都存成一般的檔案（文字檔、錄音檔、收藏的圖片），預設放在 iCloud 雲碟的 Acorn 資料夾。iCloud 是 Apple 提供的服務，怎麼處理資料請看 Apple 的隱私權政策。裝置沒登入 iCloud，或關掉 iCloud 雲碟的時候，檔案就存在這個裝置上 Acorn 自己的空間。

主題、開關這些設定存在你的裝置上。小工具和控制項要顯示你的筆記，會在裝置上讀同一份資料，不會傳到別的地方。

選 Google 雲端硬碟的時候

設定的「儲存位置」可以改成 Google 雲端硬碟。選了之後，Acorn 會打開系統的登入視窗，請你登入自己的 Google 帳號、同意授權。Acorn 跟 Google 要的只有兩樣：你的電子郵件地址，用來在設定裡顯示是哪個帳號；還有雲端硬碟的權限，而且只限 Acorn 自己建立的檔案（Google 叫它 drive.file）。你雲端硬碟裡其他的檔案，Acorn 看不到也改不了。

你的筆記會先在裝置上存一份，再從你的裝置直接傳到你自己的 Google 雲端硬碟裡、Acorn 建的那個資料夾。錄音要不要一起放上去，可以在設定選。這些傳送都不經過開發者，Acorn 也沒有伺服器。Google 給的登入憑證存在裝置的鑰匙圈。Google 雲端硬碟是 Google 提供的服務，怎麼處理資料請看 Google 的隱私權政策。

想收回授權，隨時可以到 Google 帳戶的第三方連結頁面移除 Acorn，也可以在 Acorn 的設定改回 iCloud。Acorn 使用從 Google API 取得的資料，遵守 Google API 服務使用者資料政策，包括其中的有限使用規定（Limited Use）。

語音轉文字

你講的話，預設用 Apple 內建的辨識在裝置上轉成文字，錄音不會傳出去。錄音檔會跟筆記放在一起，方便你重聽。不想留的話，到設定按「刪除所有錄音」，文字會留著。

你自己打開才會傳出去的：Groq

設定裡可以把轉文字改成用 Groq，預設是關的。打開並貼上你自己的 Groq 金鑰之後，每次錄完，Acorn 會把這段錄音、裝置上轉出來的文字、你的常用詞和專案名稱，從你的裝置直接傳到 Groq（美國的 AI 服務），讓它轉文字、改錯字、刪口頭禪。費用算在你的 Groq 帳號。

這個傳送不會經過開發者。Groq 怎麼處理這些資料，以 Groq 的隱私權政策和資料說明為準，你也可以在自己的 Groq 帳號調整資料設定。用打字記下的筆記不會送到 Groq。隨時可以改回「裝置內建」，也可以在設定刪掉金鑰。金鑰存在裝置的鑰匙圈。

收藏連結

你在別的 App 按分享、選 Acorn，連結就收進來。之後 Acorn 會用你的裝置連到那個網址，把標題、全文和封面圖存進你的資料夾，影片連結只取標題和縮圖。這跟你用瀏覽器打開網頁一樣，對方的網站看得到你的連線（例如 IP 位址）。存進去之前，網址上的追蹤參數會先拿掉。連結和內容只存在你的資料夾，不會傳給開發者或其他人。

Acorn 沒有的東西

保存和刪除

開發者手上沒有你的資料，沒有東西需要我們代刪。你的筆記在你自己的裝置，和你選的 iCloud 或 Google 雲端硬碟，想刪就自己刪。在 Acorn 裡刪掉的筆記會先放進「最近刪除」，保留 30 天，可以放回去。也可以直接到「檔案」App 或 Finder 的 iCloud 雲碟刪掉 Acorn 資料夾，存在 Google 雲端硬碟的，到雲端硬碟刪掉 Acorn 建的那個資料夾。刪除 Acorn 這個 App，不會刪掉 iCloud 雲碟或 Google 雲端硬碟裡的檔案。送到 Groq 的資料，請到你的 Groq 帳號處理。

政策更新

以後 Acorn 處理資料的方式有變，這一頁會更新，上面的日期也會跟著改。

Acorn Privacy Policy

Last updated: October 11, 2026

Acorn has no server and no Acorn account. What you write stays in your own iCloud or Google Drive. The developer cannot see it and never receives it.

Where your notes live

Your ideas, tasks, saved links, recordings, project names and custom words are stored as ordinary files (text files, audio files, saved images), by default in the Acorn folder of iCloud Drive. iCloud is an Apple service, and Apple's privacy policy covers how it handles that data. If a device is not signed in to iCloud, or iCloud Drive is turned off, the files stay in Acorn's own storage on that device.

Settings such as the theme and switches are stored on your device. Widgets and controls read the same data on the device to show your notes, and nothing is sent elsewhere.

If you choose Google Drive

In Settings you can change where notes are stored to Google Drive. When you do, Acorn opens the system sign-in window so you can sign in to your own Google account and grant access. Acorn asks Google for two things only: your email address, to show which account is in use in Settings, and access to Google Drive limited to the files Acorn itself creates (Google calls this drive.file). Acorn cannot see or change any other file in your Drive.

Your notes are first saved on your device, then sent straight from your device to the folder Acorn creates in your own Google Drive. You can choose in Settings whether recordings go there too. None of this passes through the developer, and Acorn has no server. The sign-in credential from Google is stored in the device keychain. Google Drive is a Google service, and Google's privacy policy covers how it handles that data.

To take back access, remove Acorn at any time from the third-party connections page of your Google Account, or switch back to iCloud in Acorn's Settings. Acorn's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Voice to text

By default, what you say is turned into text on your device with Apple's built-in speech recognition, and the recording is not sent anywhere. The audio file is saved next to the note so you can listen again. If you do not want to keep recordings, tap "Delete all recordings" in Settings. The text stays.

What leaves your device only if you turn it on: Groq

In Settings you can switch transcription to Groq. It is off by default. Once you turn it on and paste your own Groq API key, Acorn sends each new recording, the text transcribed on your device, your custom words and your project names straight from your device to Groq (a US-based AI service) to transcribe, fix mistakes and remove filler words. Costs go to your own Groq account.

This does not pass through the developer. How Groq handles the data is set by Groq's privacy policy and its data documentation, and you can adjust data settings in your own Groq account. Notes you type are never sent to Groq. You can switch back to on-device transcription at any time and delete the key in Settings. The key is stored in the device keychain.

Saved links

When you share a link to Acorn from another app, Acorn saves it. Later your device connects to that address and stores the title, full text and cover image in your folder. For video links it only fetches the title and thumbnail. This works like opening the page in a browser, so the website can see your connection (for example your IP address). Tracking parameters are removed from the address before it is saved. Links and content stay in your folder and are not sent to the developer or anyone else.

What Acorn does not have

Retention and deletion

The developer holds none of your data, so there is nothing for us to delete for you. Your notes are on your own devices and in the iCloud or Google Drive you chose, and you can delete them yourself. A note deleted in Acorn goes to "Recently Deleted" for 30 days and can be put back. You can also delete the Acorn folder in iCloud Drive from the Files app or Finder, or, if you use Google Drive, delete the folder Acorn created there. Deleting the Acorn app does not delete the files in iCloud Drive or Google Drive. For data sent to Groq, use your Groq account.

Changes to this policy

If the way Acorn handles data changes, this page will be updated and the date above will change with it.
