Mini Walkie Talkie is an end-to-end encrypted push-to-talk app that works online, offline, nearby, and over the internet. Add trusted contacts by scanning each other’s QR code, then press and hold to talk. Works on your iPhone, iPad, and Apple Watch (standalone). The app automatically chooses the best available route for each voice message: • Nearby first: when devices are close, the app can use Bluetooth personal area networking, shared Wi‑Fi, or peer-to-peer Wi‑Fi through Apple’s nearby device networking. • Internet direct: when both devices are online, the app can try WebRTC for a direct peer-to-peer connection across the public internet. • Encrypted relay fallback: when direct routes are not available, Pro background receiving can use an online relay. Audio remains end-to-end encrypted, and the relay only handles encrypted voice data. Mini Walkie Talkie is designed for quick private voice communication with friends, family, teams, and trusted contacts. Key features: • Push-to-talk voice messages • Works online and offline • Nearby Bluetooth/Wi‑Fi peer-to-peer communication • Internet WebRTC direct connection when available • Encrypted online relay fallback for Pro background receiving • QR code contact setup • End-to-end encrypted audio • One-to-one trusted contact communication • Recent transfer details showing which route was used • Free users can receive best-effort while the app is open • Pro users can receive more reliably in the background Privacy and encryption: Each device creates its own cryptographic identity. Contact QR codes include signed public keys so both sides can verify who they are connecting with. Voice sessions use fresh session keys, authenticated encryption, and replay protection. Your audio is encrypted before it leaves your device. Nearby devices, WebRTC peers, and the online relay only carry encrypted packets. Relay audio is temporary, limited in size and duration, and removed after the recipient receives it. Free and Pro: Free users can send and receive using nearby routes and direct internet routes while the app is open. Keep the app open for best free receiving reliability. Pro unlocks reliable background receiving with encrypted relay fallback when direct routes are unavailable. Mini Walkie Talkie is built for private, fast, route-aware voice communication — from the same room to across the Internet. Sending a message on Apple Watch requires Pro subscription. Also, receiving on Apple Watch currently only works if app is in the foreground.

重要免責聲明 Shutterguard 是一款輔助性的隱私檢查工具,無法保證偵測所有偷拍裝置。分數高不代表「一定有偷拍機」,分數低也不代表「絕對安全」。若有疑慮請立即報警(110),不要僅依賴此 app 作為判斷依據。 —— 關於 Shutterguard Shutterguard 是專為台灣使用情境設計的隱私衛生工具,協助你在進入飯店房間、更衣間、醫美診所、公共廁所隔間等場域之前,快速檢查可能藏匿針孔偷拍機的物件。 工具完全在 iPhone 本機運作,不會將任何掃描資料、影像、藍牙裝置清單上傳到任何伺服器。 —— 多手法交叉驗證 Shutterguard 同時使用多種方法獨立計分,加總成 0–90 分(鏡頭反光、紅外線為免費基礎兩項;藍牙、Wi-Fi 網段、環境異音為 Pro 計分模組;磁場為 Pro 環境資訊模組,不計分)。沒有紅黃綠燈分段——數字本身就是事實,不暗示「危險程度」。 ・鏡頭反光(最多 45 分) 免費版採閃光燈差分技術:鎖定相機曝光、白平衡與對焦後,拍下「閃光 OFF」與「閃光 ON」兩張照片,經 pixel-level 差分與 Vision 形狀辨識,找出疑似鏡頭玻璃造成的小圓形高亮反光點。 Pro 版升級為掃描式偵測(兩階段):閃光燈按偽隨機序列明滅、緩慢移動掃描(上下左右皆可),只有「跟著閃光同步明滅」的亮點才成為候選;接著引導你靠近拿穩,自動對候選點做定點確認(同步鎖定+外觀判讀+LiDAR 尺寸與深度檢查,非 LiDAR 機型自動略過對應檢查)。 ・藍牙裝置(最多 20 分,Pro 進階模組) 掃描周圍 BLE 裝置,過濾已知良性裝置(AirPods、Apple Watch 等),對「強訊號 + 無法識別」的可疑裝置依 RSSI 強度計分。 ・磁場異常(不計分,Pro 進階模組) 使用 CoreMotion 磁力計建立環境基準,偵測超出基準 2.5σ 的磁場偏移,以環境摘要呈現、不計入總分。實測任何有電器的室內都會觸發(電視、空調、熱水壺、床頭燈),鑑別力低,僅供交叉參考。 ・紅外線光點(最多 10 分) 紅外線偵測模式下用前鏡頭找暗場中的紅外線補光點(夜視攝影機特徵);也可能是遙控器、感應器等良性紅外線來源,需自行目視確認。 ・Wi-Fi 網段(最多 10 分,Pro 進階模組) 偵測連線網段下的可疑裝置。受 iOS 公開 API 限制,無法掃描周圍未連線的 Wi-Fi AP(含隱藏 SSID 偷拍機)。 ・環境異音(最多 5 分,Pro 進階模組) 透過麥克風分析 17–22 kHz 超音波頻段的異常訊號,輔助偵測可疑電子設備。不錄音、不存檔。 —— 六個情境設計 不同空間對應不同的引導路線與掃描時長: ・飯店 / 汽旅 / Airbnb(60–120 秒) 依序對準床上方、電視、空調、煙霧偵測器、浴室天花板。 ・更衣間 / 試衣間(20–30 秒) 對準天花板四角、牆面高處、掛勾、置物櫃。 ・公共廁所隔間(15–20 秒) 對準隔間上方、面紙盒、馬桶水箱、掛勾。 ・醫美 / SPA / 按摩(30–60 秒) 對準診療床正上方、偵煙器、出風口、布簾桿、儀器架。 ・出租套房 / 入住檢查(120–180 秒) 依序檢查插座延長線、時鐘擺飾、路由器、冷氣、電視周圍、書架高處。 ・天花板快掃(15–30 秒) 舉起手機環繞一圈:偵煙器、出風口、灑水頭、嵌燈。 —— 完整透明的規則公開 「掃描判斷規則」頁面完整列出每一種方法的演算法細節、計分公式、各方法上限、誤報常見原因。我們相信使用者有權知道每一分是怎麼算出來的。 —— 隱私設計 ・掃描資料完全在裝置本機運算,永不上傳任何掃描結果或影像 ・歷史紀錄套用 iOS 檔案保護加密(裝置鎖屏且未在使用時即無法被讀取) ・無第三方 SDK、無廣告 SDK、無 analytics 追蹤 ・免費版權限:相機(鏡頭反光/紅外線偵測)。Pro 進階模組另請求:藍牙(BLE 掃描)、位置(場域提醒,含背景地理圍欄)、麥克風(環境異音偵測,不錄音、不存檔)、本地網路(Wi-Fi 網段 mDNS 探索,不主動連線、不傳輸內容);磁場偵測使用磁力計,屬動作感測器、無需另外授權 —— Pro 升級(NT$120,一次買斷) ・四種進階偵測手法:藍牙裝置、磁場異常、Wi-Fi 網段、環境異音 ・掃描式鏡頭偵測(兩階段):閃光同步掃描+定點自動確認,取代免費版的單張差分比對 ・隱蔽模式:黑底介面、單手操作按鈕區、振動取代視覺提示、自動降低螢幕亮度 ・地點觸發提醒:進入飯店、醫美等預設場域時提醒掃描 ・歷史紀錄無上限(免費版上限 10 筆) ・完整證據圖:每次掃描保留打光原圖與標註全幅原圖(免費版僅保留 200×200 候選反光點縮圖) ・匯出歷史 JSON —— Pro+ 升級(NT$220,一次買斷,僅支援 LiDAR 的機型可購買) ・包含上述 Pro 全部內容(不需先買 Pro) ・LiDAR 3D 房間掃描:偵測前先建立房間立體地圖,掃描結果對應到空間位置 ・僅在 iPhone Pro 等具備 LiDAR 的機型上架售;一般機型只會看到 Pro 選項 —— 工具的限制(請務必理解) ・鏡頭反光偵測為啟發式判斷,日常物品如金屬把手、眼鏡、手錶、玻璃裝飾品都可能被偵測 ・受 iOS 公開 API 限制,第三方 app 無法掃描周圍未連線的 Wi-Fi AP(含隱藏 SSID 偷拍機) ・BLE 偵測受 iOS 限制無法取得 MAC address,無法判斷品牌或型號 ・磁力計受環境干擾大,誤報率高,僅作交叉參考用 ・Shutterguard 不能取代專業 RF 掃描設備或法律救濟管道 如果你有具體的偷拍疑慮,請立即報警(110),並向場域管理單位或訂房平台反映。 —— 開發團隊 由獨立開發者於台灣製作,所有文案、邏輯與設計皆專為台灣使用情境調整。Pull request 與 issue 歡迎於開發者公開的 GitHub 頁面提交。 —— 支援與回饋 ・隱私說明:app 內「設定 → 隱私與條款 → 隱私說明」 ・掃描規則:app 內「設定 → 說明與教學 → 掃描判斷規則」 ・常見偽裝型態:app 內「設定 → 說明與教學 → 常見偷拍裝置偽裝型態」 ・官網:https://shutterguard.pages.dev
