Telltale 隱私權政策
最後更新：2026 年 8 月 18 日
Telltale 不收集、不上傳、不分享任何資料。 沒有帳號、沒有廣告、沒有分析、沒有當機回報服務。App 唯一會連線的對象是你插在車上的那個 ELM327 轉接器。
我們收集哪些資料
沒有。Telltale 不會收集個人資料，也不會把任何資料傳送到我們或第三方的 伺服器。我們沒有伺服器。
App 在你裝置上儲存哪些東西
以下全部只存在你的手機裡，不會離開裝置，解除安裝時一併移除：
| 內容 | 為什麼 |
|---|---|
| 你的車輛設定（排氣量、車重、風阻係數等） | 推算馬力與油耗需要 |
| 你自訂的 PID 定義 | 這是你寫的東西 |
| 上次使用的轉接器與 Wi-Fi 位址 | 下次不用再找一遍 |
| 介面設定（深色／淺色、儀表樣式） | 記住你的選擇 |
| 診斷紀錄（最後一次連線） | 連不上時可以匯出給人看 |
診斷紀錄值得特別說明：它記錄 App 與轉接器之間往返的原始位元組，包括車輛 回報的 VIN 與故障碼。它只寫在 App 的私有目錄，只有你按下「匯出」時才會離開 App，而且是由你決定要傳給誰。App 從來不會自己送出它。
網路連線
Telltale 需要 INTERNET 權限，但不用來連上網際網路。它只用來對
Wi-Fi 型 ELM327 轉接器開啟一條 TCP 連線 —— 那是一個區域位址（通常是
192.168.0.10:35000），Android 沒有更精確的權限可以表達「只連本地」。
App 不會發出任何其他網路要求。你可以在飛航模式下（開著藍牙）完整使用它。
權限說明
| 權限 | 用途 |
|---|---|
BLUETOOTH_CONNECT | 連線到已配對的 ELM327 轉接器 |
BLUETOOTH_SCAN | 搜尋尚未配對的 BLE 轉接器（宣告 neverForLocation） |
BLUETOOTH / BLUETOOTH_ADMIN | Android 11 以下的等效權限 |
ACCESS_FINE_LOCATION / ACCESS_COARSE_LOCATION |
僅限 Android 11 以下（maxSdkVersion="30"）。舊版 Android 把 BLE
掃描歸在位置權限底下，這是系統規定，不是我們要你的位置。App 不讀取、不儲存、不傳送
任何位置資訊 |
INTERNET / ACCESS_NETWORK_STATE | 連線 Wi-Fi 型轉接器（見上） |
BLUETOOTH_ADVERTISE 在本 App 的資訊清單中以 tools:node="remove"
明確移除。這個 App 只當客戶端 —— 它連到轉接器，從不讓手機自己變成可被發現的裝置。移除而非
單純不寫，是因為 Android 的資訊清單以聯集合併：只要任何一個相依套件宣告了它，不寫就等於
預設帶上。（2026-08-18 實測合併後的資訊清單：目前沒有任何相依套件宣告它，所以這是保險
而不是修正。）
第三方服務
沒有。App 沒有整合任何分析、廣告、當機回報或行銷 SDK。你可以在
原始碼的 pubspec.yaml
裡自行確認相依套件清單。
兒童
本 App 不針對兒童設計，也不會在知情的情況下收集兒童資料 —— 事實上它不收集任何人的資料。
付費與退款
Google Play 處理所有付款。我們看不到你的付款資訊。退款依 Google Play 的政策辦理。
開放原始碼
Telltale 以 GPL-3.0 授權開放原始碼。本政策所述的每一項，你都可以在 原始碼中自行驗證 —— 這比任何一份隱私權政策的 文字都更值得相信。
變更
本政策若有變更，會更新本頁的日期並在 GitHub 的版本紀錄中留下完整差異。

Telltale Privacy Policy
Last updated: 18 August 2026
Telltale collects nothing, uploads nothing, and shares nothing. No accounts, no ads, no analytics, no crash reporting. The only thing it connects to is the ELM327 adapter plugged into your car.
What we collect
Nothing. We have no servers.
What the app stores on your device
Vehicle profile, your custom PID definitions, the last adapter used, interface preferences, and a diagnostic transcript of the most recent session. All of it stays in the app's private storage and is removed when you uninstall.
The diagnostic transcript records the raw bytes exchanged with the adapter, including the VIN and fault codes the vehicle reports. It leaves the app only when you press Export, and only to a destination you choose. The app never sends it anywhere on its own.
Network access
The INTERNET permission is not used to reach the internet. It opens a TCP
connection to a Wi-Fi ELM327 adapter on a local address — Android has no narrower permission
for "local network only". The app makes no other network requests and works fully in
aeroplane mode with Bluetooth on.
Permissions
| Permission | What it is for |
|---|---|
BLUETOOTH_CONNECT | Connecting to a paired ELM327 adapter |
BLUETOOTH_SCAN | Finding an unpaired BLE adapter (declared neverForLocation) |
BLUETOOTH / BLUETOOTH_ADMIN | The equivalents on Android 11 and below |
ACCESS_FINE_LOCATION / ACCESS_COARSE_LOCATION |
Android 11 and below only (maxSdkVersion="30"). Older Android
files BLE scanning under the location permission. That is the system's rule, not us asking
where you are: the app never reads, stores or transmits any location. |
INTERNET / ACCESS_NETWORK_STATE | Reaching a Wi-Fi adapter (see above) |
BLUETOOTH_ADVERTISE is explicitly removed from this app's manifest with
tools:node="remove". This app is a client — it connects to an adapter and never makes
your phone discoverable. Removed rather than merely omitted, because Android merges manifests by
union: one dependency declaring it would be enough to ship it. (Checked against the merged manifest
on 2026-08-18: no current dependency declares it, so this is insurance rather than a correction.)
Third-party services
None. No analytics, advertising, crash reporting or marketing SDKs. You can verify this
yourself in pubspec.yaml in the
source.
Children
This app is not directed at children and does not knowingly collect data from them — in fact it collects data from no one.
Payment and refunds
Google Play handles all payments. We never see your payment details. Refunds follow Google Play's policy.
Open source
Telltale is GPL-3.0. Every claim in this policy is verifiable in the source, which is worth more than the policy text.
Changes
If this policy changes, the date on this page changes with it and the full diff stays in the GitHub history.
