Effective date: 2026-10-19　Last updated: 2026-10-19

Short version

  • Cam2gether has no accounts and no developer server.
  • The photos and videos you take are stored on your iPhone. Cam2gether does not upload them, and the developer cannot see them.
  • The app has no ads, no analytics, no tracking and no third-party SDKs.
  • If you allow Location, coordinates are sent to Apple's service to get a city name. See sections 4 and 7.
  • Apple handles payment and subscriptions. The developer does not receive your payment details, name or credit card. The app only asks Apple, on your iPhone, whether you have a subscription. See sections 4 and 6.
  • The monthly free quota counter is kept only on your iPhone, and the developer cannot see it. See section 6.
  • Without a subscription, photos and videos you save to Photos or share carry a Cam2gether watermark, and you can turn it off while you are subscribed. The in-app Library and the live preview do not show it. See section 6.
  • The developer receives content only when you choose to email the developer. See section 10.

1. Who is behind the app

"Cam2gether" (Traditional Chinese store name "Cam2gether 來拍！") is an iPhone app. It shoots with the front and rear cameras at the same time and saves one photo or one video.

The app is provided by 劉韶颺, an individual developer. Below, "the developer".

Contact email: shawnliu0x36@gmail.com

This policy explains how the current version of Cam2gether handles data.

2. What the app uses, and why

Cam2gether asks iOS for the features below only when it needs them. You can turn any of them off at any time in the iPhone Settings app.

  • Camera: uses the front and rear cameras together to preview, take photos and record videos. iOS asks the first time you open the app. If you do not allow it, the app shows an explanation and an "Open Settings" button.
  • Microphone: records the sound of your videos only. iOS asks when you enter Video mode, not when you take photos. If you do not allow it, videos have no sound.
  • Location (While Using the App): adds a place to your photos and videos. iOS asks after the first photo or video is finished, so the first one has no place. The app uses "While Using the App" only: no "Always", and no background location. If you do not allow it, you can still take photos and record videos, they just have no place. Details are in section 7.
  • Photos (save and browse): saves your photos and videos to the iPhone Photos app, creates an album named "Cam2gether", and lets you browse that album inside the app. iOS asks the first time you save to Photos (by hand or with Auto-Save) or the first time you open that album. The app asks for read and write access. But it only uses its own "Cam2gether" album. It does not list or read the other photos in your library. If you only allow "Limited" access, the app asks you to allow full access when you browse that album, and a copy you save may not be placed in the "Cam2gether" album. The media inside the app is not affected.
  • What it does not use: contacts, calendars, health data, Bluetooth and notifications. The app does not ask for the "tracking" permission either.

3. Data stored on your iPhone, for how long, and how to delete it

What is stored, and where:

  • Photos and videos: after you shoot, they are kept in Cam2gether's own folder on your iPhone until you delete them. Nothing is deleted automatically by default. Temporary capture files are cleared the next time you open the app.
  • Saving to Photos: Auto-Save is off by default. You can save by hand or turn Auto-Save on yourself. The app asks you first, and it only applies to what you shoot afterwards. Copies saved to Photos belong to your Photos library. If you use iCloud Photos, they sync according to your settings.
  • Location record of each item: see section 7.
  • Settings: quality, language, whether you have seen the tutorial, the watermark switch (you can turn the watermark off while subscribed, and the choice stays after a subscription ends), and the identifier of the Cam2gether album. They stay in the app and disappear when you uninstall it.
  • Quota counter: how many photos and videos of this month's free quota you have used, and the time your months are counted from, kept by the app on your iPhone in two places: the app's settings data and the iOS Keychain (not synced to iCloud). See section 6.
  • Subscription status: managed by Apple's StoreKit. The app does not store your payment details; when it needs the status it asks Apple, on your iPhone. So that the app can decide before StoreKit answers on the next launch, it keeps on your iPhone the last subscription state Apple confirmed (the plan, the end of the current period, when it was confirmed, whether it renews), and updates or removes it after each check with Apple. See section 6.
  • Diagnostic file: the app keeps a diagnostic file on your iPhone. It contains the device model, iOS version, device name, and records of camera capability and performance. It contains no photos, videos or locations. It is never sent anywhere. You cannot see it in the app, there is no button to delete it, and "Clear All Local Media Now" does not clear it. Uninstalling the app deletes it.
  • Backups: iPhone backups (iCloud backup or computer backup) may include Cam2gether's media and settings. The copy of the quota counter in the app's settings data may be included too; the Keychain copy is not synced to iCloud. Your Apple account or your computer keeps those backups. The developer cannot access them.
  • Backup copy after damage: if the app's media index is damaged, the app keeps a copy that includes location records. That copy is never deleted automatically; it goes away when you uninstall the app. This is rare.

How to delete:

  • Select one or more items in the app's Library and delete them. The app asks you first.
  • Inside the app, open Settings, then tap "Library Settings". To open Settings: tap the "..." button at the top right of the camera screen (Camera tools), then tap the gear icon (Settings) in the tools bar that opens, or tap the gear icon at the top left of the Library. This "Settings" is the app's own settings, not the iPhone Settings app.
  • In "Library Settings", "Clear Items Saved to Photos" clears only the items in the app that are already saved to Photos. "Clear All Local Media Now" shows the count and size first, then asks you to confirm. "Clear Cache" removes leftover temporary files only; it does not touch photos or videos.
  • "Auto-Delete" is "None" by default. You can choose 24 hr, 7 days or 1 month, and the app asks you to confirm. Items past the period are deleted, including photos and videos that are not saved to Photos. It runs when you open or return to the app, not at an exact time. If the app is not sure whether an item was saved to Photos, Auto-Delete keeps it.
  • These deletions are permanent. Cam2gether has no "Recently Deleted" to recover from.
  • These functions do not delete the copies in Photos. To delete those copies, use the Photos app.
  • Uninstalling the app removes the app's data (library, index, diagnostic file, settings, and the copy of the quota counter kept in the app's settings data). The Keychain copy of the quota counter may still be on this iPhone; see section 6. Copies already in Photos, files you shared, and older data inside backups are not covered.

4. What leaves your iPhone, and who gets it

Cam2gether has no developer server, and the app does not contain its own networking code. Anything that touches the network is an Apple system service. Data leaves your iPhone only in the cases below.

  • Apple's geocoding service: if you allow Location, the app gives coordinates to Apple's geocoding service to get a city and region name. This happens at most about once a minute while the app is open and Location is allowed. The developer cannot see these coordinates and cannot access Apple's side of the data. For Apple's general explanations, see Location Services & Privacy and Apple's Privacy Policy.
  • iCloud Photos: if you turn on iCloud Photos, the copies you save to Photos sync to your own iCloud according to your settings. When you browse the "Cam2gether" album, iOS may also download a photo that exists only in iCloud from your own iCloud. All of this is between you and Apple.
  • When you tap Share: you pick the item, then pick which app or person receives it, and only then does the file leave. You decide the recipient. Cam2gether cannot see it and does not log it. A shared photo or video file may carry general technical information from the camera, such as the device model and the time it was taken.
  • When you email the developer: if you write an email and attach a screenshot, the content of the email goes to the developer's mailbox. See section 10.
  • Purchases, subscriptions and redemption codes (Apple): Apple handles payment, renewal, cancellation and refunds. Cam2gether uses Apple's StoreKit to ask Apple, on your iPhone, whether you have an active subscription. Your payment details, name and credit card stay between you and Apple, and the developer does not receive them. A redemption code is entered in Apple's redemption window and handled by Apple. See section 6.

Also, the developer may see summary statistics from Apple in App Store Connect, such as download counts, summary reports on sales and subscriptions, and crash and diagnostic reports from users who chose in iOS to share them with developers. Apple produces these and decides what they contain; they are not data sent by Cam2gether.

5. What the developer does not do

  • No accounts: no sign-up and no sign-in.
  • No ads: the app has no ads.
  • No analytics or crash reporting tools in the app: Cam2gether includes none.
  • No tracking: the app does no cross-app or cross-website tracking, does not ask for the "tracking" permission, and has no advertising identifier.
  • No third-party SDKs: the app only uses what Apple provides. No one else's libraries are included.
  • No handling of your payment: Apple handles payment. The developer does not receive your payment details, name or credit card.
  • No selling your data: the app itself does not collect your personal data, so there is nothing to sell. Emails you send to the developer are not sold either; see section 10.

6. Purchases, subscription, free quota and watermark

This section explains how Cam2gether's paid model handles data. The paid terms themselves (prices, trial, renewal, cancellation) are in the Terms of Use.

Free quota

  • The two-camera modes (picture-in-picture, top and bottom, left and right) have a monthly free quota: 30 photos and 10 videos, counted separately. The quota resets every month.
  • What counts against the quota is a finished photo or video that was successfully saved into Cam2gether's Library.
  • The month starts when this iPhone first reads the quota record (usually the first time you open the app), and the quota then resets on the same day and time each month; in a shorter month that does not have that day, it resets on the last day of that month. So the reset time differs from iPhone to iPhone and is not fixed on the 1st of the month. Unused quota does not carry over to the next month. The app shows when the next reset is.
  • Normal (single camera) mode does not count against the quota. Opening the camera and the preview are never locked.
  • When one kind of quota is used up and you have no subscription, you need a subscription to keep shooting that kind of content with both cameras until the next reset. Normal single-camera shooting stays available. Content you already shot is not deleted because of this.
  • Where the quota counter is kept: the app records it on your iPhone in two places: the app's settings data (UserDefaults) and the iOS Keychain (set to not sync to iCloud and not to move to another iPhone). It holds how many photos and videos you have used this month, the time your months are counted from, when this month began, and up to the last 64 random capture operation IDs (used so that one capture is not counted twice; they have nothing to do with you or your device). It contains no photos, videos, locations or your name, and no device or user identifier. The developer has no server, cannot see this record and does not receive it.
  • After a reinstall: after you reinstall the app, move to a new iPhone or restore a backup, the quota counter may be kept or may start over. Whether the Keychain copy survives and what a backup carries over depends on how iOS treats the data an app leaves on the device, and the developer cannot guarantee either result. Cam2gether has no account, so the developer also has no way to recover or reset your quota on a new iPhone, and the app has no function to reset the quota.

Subscription and payment

  • Subscription plans are in the "Cam2gether Pro" subscription group: weekly, monthly and yearly, all auto-renewing. Prices and conditions are those shown on the in-app purchase screen and in the App Store; see also the Terms of Use.
  • While you are subscribed, two-camera capture is not limited by the monthly quota, and you can turn the watermark off in "Settings > Watermark".
  • Apple handles payment, renewal, cancellation and refunds, tied to your Apple Account. The developer does not receive your payment details, name or credit card.
  • Cam2gether uses Apple's StoreKit to ask Apple, on your iPhone, whether you have an active subscription, and then decides whether to allow unlimited two-camera capture and the option to turn the watermark off. This step is between your iPhone and Apple. Cam2gether has no server of its own and no receipt-validation service of its own.
  • Apple keeps the subscription status. The app does not store your payment details; it only keeps on your iPhone the last subscription state Apple confirmed, see section 3.
  • The app has "Restore Purchases" and "Redeem Offer Code" (in "Settings > Cam2gether Pro", and at the bottom of the subscription screen). While you are subscribed you also see "Manage or Cancel Subscription", which opens Apple's subscription screen. Apple handles all of these.
  • Redemption codes: offer codes are Apple offer codes only. "Redeem Offer Code" only opens Apple's redemption window; you enter the code there and Apple handles it. Cam2gether has no input field of its own and does not collect or validate redemption codes itself.

The watermark

  • Without a subscription, at the moment you save a photo or video to Photos or share it, Cam2gether adds a Cam2gether watermark to the result. This includes two-camera results, Normal single-camera results, and snapshots taken while recording.
  • The watermark is not added when you shoot. The in-app Library and the live preview never show it; it appears only on the files you save or share.
  • Whether the watermark is added depends on your subscription state at the moment you save or share, not on the state when you shot.
  • The watermark sits at the bottom center of the picture and includes a small "TW" mark (TW stands for Taiwan).
  • The watermark is a fixed image built into the app. It shows the Cam2gether wordmark and logo. It does not contain your name, account, date or location.
  • While you are subscribed you can turn it off in "Settings > Watermark". After that, everything you save or share (including items shot earlier) has no watermark. Without a subscription the switch shows as on, and trying to turn it off opens the subscription screen; the watermark stays on. When a subscription ends, everything you save or share afterwards (including items shot while you were subscribed) carries the watermark again; your choice in "Settings > Watermark" is kept and applies again if you subscribe again. Files already saved to Photos or already shared are not changed.
  • The watermark is added on your iPhone, directly into the picture. It does not send your photos or videos anywhere. If the watermark cannot be added, nothing is saved or shared that time.

7. Location details

  • When it locates: only while you have the app open, Location is allowed and the camera is allowed. It stops when you leave the app and throws away the location held in memory.
  • Accuracy: the app asks for about 100 meter accuracy. You can also give only "Approximate Location" in iOS; the app marks it as approximate.
  • Which locations are used: at capture time, only a location taken within the last 60 seconds with an error of 1000 meters or less is used. Otherwise that photo or video gets no place.
  • What is stored: each item's record stores latitude, longitude, altitude (when its vertical accuracy is valid), horizontal accuracy, time, the city and region name, and whether it is approximate. Coordinates are kept at full precision; the app screens only show shorter numbers.
  • Where it is stored: (1) in Cam2gether's records on your iPhone. (2) When you save an item to Photos, the location (coordinates, horizontal accuracy, time) is written to that entry in Photos, as long as Location is still allowed. The city and region name stays only in Cam2gether's records and is not written to Photos.
  • Not written into the file: Cam2gether does not write the location into the photo or video file itself.
  • Shown in the app: the Library can group items by place, and an item's "Media Information" shows the place name or coordinates. These screens exist only on your iPhone.
  • Sent to Apple: getting a city name needs Apple's geocoding service. See section 4.
  • Turning it off: when you turn Location off, the app stops locating right away and throws away the location in memory. A location already stored in an item's record is not removed automatically. It goes away when you delete that item. There is no "remove location only" function today. For a copy already saved to Photos, handle its location in the Photos app.

8. Children

  • Cam2gether is not designed for children. It has no features aimed at children and is not in Apple's Kids category.
  • The app itself does not collect anyone's personal data, and it does not ask for age.
  • If someone, including a child, writes to the developer on their own, the developer receives the content of that email; see section 10 for how it is handled. A parent or guardian can email at any time to ask for it to be deleted.
  • Purchases in the app are handled by Apple, and the developer does not receive payment details. A parent or guardian who wants to limit purchases can use the controls Apple provides on the iPhone, such as Screen Time.
  • If you are a parent or guardian and have concerns, you can also delete content as described in section 3, or turn off the app's camera and other permissions in the iPhone Settings app.

9. Changes to this policy

If the way the app handles data changes (for example, a subscription plan is adjusted, or a feature that uses data is added), the developer will update this page and the "Last updated" date above. Please check back from time to time.

10. Contact

For questions about this policy or your data, email shawnliu0x36@gmail.com.

Provider: 劉韶颺

The data in the app is on your iPhone, so you can do most viewing and deleting yourself there. See section 3. Emails you send to the developer are handled as described below.

When you email the developer

The app itself never sends any data to the developer. But if you write to the developer, for example to report a problem or ask about this policy, the developer receives what you choose to send.

  • What the developer receives: your email address, what you write in the email, and any files you attach (for example a screenshot). If you follow the support page and write your device model, iOS version and a description of what you did, the developer receives that too.
  • What it is used for: only to reply to you and to sort out the problem. It is not used to send you ads and it is not sold.
  • Where it is kept: in the email service the developer uses to receive mail.
  • How long: kept for at most 12 months after the problem is resolved, then deleted.
  • Asking for deletion: you can email shawnliu0x36@gmail.com at any time and ask the developer to delete the emails and attachments you sent. The developer will delete them.
  • Attachments: please do not attach photos or screens you do not want the developer to see. Please also do not write a credit card number or other payment details in the email; ask Apple for refunds, see the Terms of Use.

簡短版

  • Cam2gether 沒有帳號，也沒有開發者的伺服器。
  • 你拍的照片和影片存在你的 iPhone。Cam2gether 不會上傳，開發者看不到。
  • App 裡沒有廣告、分析工具、追蹤，也沒有第三方 SDK。
  • 如果你允許定位，座標會送到 Apple 的服務，換成城市名稱。見第 4 節和第 7 節。
  • 付款與訂閱由 Apple 處理。開發者不會收到你的付款資料、姓名或信用卡。App 只在你的 iPhone 上向 Apple 查詢訂閱狀態。見第 4 節和第 6 節。
  • 每月免費額度的計數只存在你的 iPhone，開發者看不到。見第 6 節。
  • 沒有訂閱時，儲存到「照片」或分享出去的照片和影片會加上 Cam2gether 浮水印，訂閱後可以關閉。App 內的媒體庫和即時預覽不會顯示浮水印。見第 6 節。
  • 只有你自己寫信給開發者時，開發者才會收到你寄來的內容。見第 10 節。

1. 開發者是誰

「Cam2gether 來拍！」（英文名稱 Cam2gether）是一個 iPhone App。它用前後鏡頭同時拍攝，存成一張照片或一支影片。

App 的提供者是 劉韶颺，是個人開發者。下文稱「開發者」。

聯絡信箱：shawnliu0x36@gmail.com

這份政策說明 Cam2gether 目前的版本怎麼處理資料。

2. App 會取用什麼，為什麼

Cam2gether 只在需要時，請 iOS 讓它使用下面的功能。你可以隨時到 iPhone 的「設定」關閉。

  • 相機：同時使用前後鏡頭，用來預覽、拍照和錄影。第一次開啟 App 時會詢問。如果你不允許，App 會顯示說明和「前往設定」按鈕。
  • 麥克風：只用來錄影片的聲音。你進入影片模式時才會詢問，拍照不會問。如果你不允許，影片會沒有聲音。
  • 定位（使用 App 期間）：替照片和影片加上拍攝地點。第一次拍完照片或影片之後才會詢問，所以第一張不會有地點。只有「使用 App 期間」，沒有「永遠」，也沒有背景定位。如果你不允許，還是可以拍照和錄影，只是不會有地點。細節見第 7 節。
  • 照片（儲存和瀏覽）：把照片和影片存進 iPhone 的「照片」，建立一個叫「Cam2gether」的相簿，並在 App 裡瀏覽這個相簿。第一次儲存到「照片」（手動儲存或 Auto-Save），或第一次打開這個相簿時，iOS 會詢問。App 要求的是「讀取和寫入」權限。但它只會取用自己建立的「Cam2gether」相簿，不會列出或讀取你圖庫裡的其他照片。如果你只允許「部分照片」，瀏覽這個相簿時 App 會請你改成完整取用，而且儲存的副本可能不會放進「Cam2gether」相簿。App 裡的媒體不受影響。
  • 沒有取用的東西：聯絡人、行事曆、健康資料、藍牙、通知，都沒有用。App 也不要求「追蹤」權限。

3. 存在你 iPhone 上的資料、保留多久、怎麼刪除

存了什麼，存在哪裡：

  • 照片和影片：拍完後存在 Cam2gether 自己的資料夾，在你的 iPhone 上，留到你刪除為止。預設不會自動刪除。拍攝過程中的暫存檔，會在你下次開啟 App 時清除。
  • 儲存到「照片」：Auto-Save 預設是關的。你可以手動儲存，或自己開啟 Auto-Save。開啟前 App 會先問你，而且只對之後拍的內容生效。存進「照片」的副本屬於你的「照片」圖庫。如果你開了 iCloud 照片，會依你的設定同步。
  • 每個項目的位置紀錄：見第 7 節。
  • 設定：畫質、語言、教學是否看過、浮水印開關（訂閱後可以關閉，訂閱結束後這個選擇仍會保留），以及 Cam2gether 相簿的識別碼。它們留在 App 裡，解除安裝就消失。
  • 額度計數：這個月的免費額度已經用掉幾張照片、幾部影片，以及每月額度的起算時間，由 App 記在你的 iPhone 上，有兩份：App 的設定資料，和 iOS 的鑰匙圈（Keychain，不同步 iCloud）。見第 6 節。
  • 訂閱狀態：由 Apple 的 StoreKit 管理。App 不另外存你的付款資料，需要時在你的 iPhone 上向 Apple 查詢。為了讓下次啟動時，StoreKit 還沒回覆前也能判斷，App 會在 iPhone 上暫存最近一次向 Apple 確認到的訂閱狀態（方案、這一期的到期日、確認時間、是否已取消續訂），每次向 Apple 確認後就更新或刪除。見第 6 節。
  • 診斷檔：App 會在你的 iPhone 裡存一份診斷檔，內容是機型、iOS 版本、裝置名稱，以及相機能力和效能的紀錄。裡面沒有照片、影片或位置。它不會傳出去。你在 App 裡看不到它，也沒有按鈕可以刪除，「立即清除 App 內全部媒體」也不會清它。解除安裝 App 才會刪除。
  • 備份：iPhone 的備份（iCloud 備份或電腦備份）可能包含 Cam2gether 的媒體和設定。額度計數在 App 設定資料裡的那一份也可能包含在內；鑰匙圈那一份不同步 iCloud。備份由你的 Apple 帳號或電腦保管，開發者拿不到。
  • 損毀時的備份檔：如果 App 的媒體索引壞掉，App 會留一份副本，裡面含位置紀錄。這個副本不會被自動刪除，要解除安裝 App 才會消失。這種情況很少見。

怎麼刪除：

  • 在 App 的媒體庫選取一個或多個項目後刪除。刪除前會先問你。
  • 在 App 裡開啟設定，再點「Library 設定」。開啟設定的方法：點相機畫面右上角的「…」（相機工具），再點工具列裡的齒輪圖示（設定）；或在媒體庫左上角點齒輪圖示。這裡的「設定」是 App 裡的設定，不是 iPhone 的「設定」。
  • 「Library 設定」裡，「清除已儲存到照片的項目」只清掉 App 裡已經存進「照片」的項目。「立即清除 App 內全部媒體」會先顯示數量和大小，再請你確認。「清除 Cache」只清殘留的暫存檔，不動照片和影片。
  • 「自動刪除」預設是「無」。你可以改成 24 小時、7 天或 1 個月，選了之後會先請你確認。到期的項目都會刪除，包含還沒儲存到「照片」的照片和影片。它在你開啟或回到 App 時才會執行，不會準時刪。如果 App 不確定某個項目有沒有存進「照片」，自動刪除會保留它。
  • 這些刪除都是永久的。Cam2gether 沒有「最近刪除」可以復原。
  • 這些功能不會刪除「照片」裡的副本。要刪那些副本，請到「照片」App。
  • 解除安裝 App 會移除 App 裡的資料（媒體庫、索引、診斷檔、設定，以及存在 App 設定資料裡的那一份額度計數）。鑰匙圈那一份額度計數可能還留在這支 iPhone 上，見第 6 節。已存進「照片」的副本、你分享出去的檔案，以及備份裡的舊資料，不在這個範圍。

4. 哪些資料會離開你的 iPhone，給誰

Cam2gether 沒有開發者的伺服器，程式也沒有自己寫網路連線的程式碼。會碰到網路的，都是 Apple 的系統服務。資料只會在下面幾種情況離開你的 iPhone。

  • Apple 的地理編碼服務：如果你允許定位，App 會把座標交給 Apple 的地理編碼服務，換成城市和行政區的名稱。App 開著而且允許定位時，最多約每分鐘一次。開發者看不到這些座標，也拿不到 Apple 那邊的資料。Apple 的一般說明請看 Location Services & Privacy 和 Apple 的隱私權政策。
  • iCloud 照片：如果你開啟 iCloud 照片，存進「照片」的副本會依你的設定同步到你自己的 iCloud。瀏覽「Cam2gether」相簿時，如果某張照片只存在 iCloud，iOS 也會從你自己的 iCloud 下載它。這些都發生在你和 Apple 之間。
  • 你按下分享：你選擇要分享的項目，再選擇要傳給哪個 App 或哪個人，檔案才會離開。對象由你決定。Cam2gether 看不到，也不會記錄。分享出去的照片或影片檔，可能帶有相機的一般技術資訊，例如機型和拍攝時間。
  • 你寄信給開發者：你自己寫信、附上截圖時，信的內容會寄到開發者的信箱。見第 10 節。
  • 購買、訂閱與兌換碼（Apple）：付款、續訂、取消和退款都由 Apple 處理。Cam2gether 用 Apple 的 StoreKit，在你的 iPhone 上向 Apple 查詢你有沒有有效的訂閱。你的付款資料、姓名和信用卡，都只在你和 Apple 之間，開發者不會收到。兌換碼是輸入在 Apple 的兌換視窗，由 Apple 處理。見第 6 節。

另外，開發者在 App Store Connect 可能會看到 Apple 提供的彙整統計（例如下載量、銷售與訂閱的彙整報表），以及使用者在 iOS 裡選擇與開發者分享的當機與診斷報告。這些由 Apple 產生，內容由 Apple 決定，不是 Cam2gether 傳出的資料。

5. 開發者不做的事

  • 沒有帳號：不用註冊，也不用登入。
  • 沒有廣告：App 裡沒有廣告。
  • App 裡沒有分析和當機回報工具：Cam2gether 沒有放進任何分析或當機回報程式。
  • 不追蹤你：App 不做跨 App 或跨網站的追蹤，不要求「追蹤」權限，也沒有廣告識別碼。
  • 沒有第三方 SDK：App 只用 Apple 提供的功能，沒有放進別人的程式庫。
  • 不經手你的付款：付款由 Apple 處理，開發者不會收到你的付款資料、姓名或信用卡。
  • 不出售你的資料：App 本身不蒐集你的個人資料，所以沒有東西可以出售。你寄給開發者的信件也不會被出售，見第 10 節。

6. 購買、訂閱、免費額度與浮水印

這一節說明 Cam2gether 的收費方式怎麼處理資料。收費條件本身（價格、試用、續訂、取消）在使用條款。

免費額度

  • 雙鏡頭同框模式（子母畫面、上下分割、左右分割）每月有免費額度：30 張照片和 10 部影片，照片和影片分開計算。額度每月重置。
  • 計入額度的，是成功存入 Cam2gether 媒體庫的成品。
  • 額度從這支 iPhone 第一次讀取額度紀錄的時候起算（通常是第一次開啟 App 時），之後每個月在同一天、同一時刻重置；遇到比較短、沒有那一天的月份，就在那個月的最後一天重置。所以每支 iPhone 的重置時間不同，不是固定在每月 1 日。用不完的額度不會累積到下個月。App 會顯示下次重置的時間。
  • Normal（單一鏡頭）拍攝模式不計入額度。相機開啟和預覽也不會被鎖住。
  • 某一種額度用完之後，到下次重置之前，要繼續用雙鏡頭拍攝那一種內容就需要訂閱。Normal 單鏡拍攝仍然可以使用。已經拍好的內容不會因此被刪除。
  • 額度計數存在哪裡：由 App 記在你的 iPhone 上，有兩份：App 的設定資料（UserDefaults），和 iOS 的鑰匙圈（Keychain；設定為不同步 iCloud，也不會搬到另一支 iPhone）。內容是這個月已用掉的照片張數和影片部數、每月額度的起算時間與這個月的開始時間，以及最近最多 64 個隨機產生的拍攝作業編號（用來避免同一次拍攝被重複計數，和你或你的裝置無關）。它不含照片、影片、位置或你的姓名，也沒有任何裝置或使用者識別碼。開發者沒有伺服器，看不到這份紀錄，也不會收到它。
  • 重新安裝之後：重新安裝 App、換新 iPhone 或還原備份之後，額度計數可能保留，也可能重新開始。鑰匙圈那一份留不留得住、備份會搬什麼過去，取決於 iOS 怎麼處理 App 留在裝置上的資料，開發者無法保證。Cam2gether 沒有帳號，所以開發者也沒有辦法在新的 iPhone 上替你找回或重設額度，App 裡也沒有重置額度的功能。

訂閱與付款

  • 訂閱方案放在「Cam2gether Pro」訂閱群組，有週訂、月訂、年訂，都會自動續訂。價格與條件以 App 裡的購買畫面和 App Store 顯示為準，也見使用條款。
  • 訂閱期間，雙鏡頭同框拍攝不受每月額度限制，也可以到「設定 › 浮水印」關閉浮水印。
  • 付款、續訂、取消和退款都由 Apple 處理，綁定你的 Apple 帳號。開發者不會收到你的付款資料、姓名或信用卡。
  • Cam2gether 用 Apple 的 StoreKit，在你的 iPhone 上向 Apple 查詢你有沒有有效的訂閱，再決定要不要開放不限量的雙鏡頭拍攝和關閉浮水印的選項。這一步發生在你的 iPhone 和 Apple 之間。Cam2gether 沒有自己的伺服器，也沒有自己的收據驗證服務。
  • 訂閱狀態由 Apple 保管。App 不另外存你的付款資料，只在你的 iPhone 上暫存最近一次向 Apple 確認到的訂閱狀態，見第 3 節。
  • App 裡有「回復購買項目」和「兌換優惠碼」（在「設定 › Cam2gether Pro」，訂閱畫面最下面也有）。訂閱中的人還會看到「管理或取消訂閱」，它會打開 Apple 的訂閱畫面。這些都由 Apple 處理。
  • 兌換碼：優惠碼只使用 Apple 的優惠代碼（offer code）。「兌換優惠碼」只會打開 Apple 的兌換視窗，你在那裡輸入，由 Apple 處理。Cam2gether 自己沒有輸入欄位，也不自己收集或驗證兌換碼。

浮水印

  • 沒有訂閱時，你把照片和影片儲存到「照片」或分享出去的那一刻，Cam2gether 會在成品上加一個 Cam2gether 浮水印。這包括雙鏡頭的成品、Normal 單鏡的成品，以及錄影中擷取的快照。
  • 浮水印不是拍攝時加的。App 內的媒體庫和相機的即時預覽都不會顯示浮水印，它只出現在你儲存或分享出去的檔案上。
  • 是否加浮水印，依你「儲存或分享那一刻」的訂閱狀態決定，不是依拍攝時的狀態。
  • 浮水印放在畫面底部中間，裡面有一個小小的「TW」標記（TW 代表 Taiwan）。
  • 浮水印是 App 內建的固定圖案，內容是 Cam2gether 的字樣和標誌。它不含你的姓名、帳號、日期或位置。
  • 訂閱期間，你可以到「設定 › 浮水印」關閉它。關閉後，之後儲存或分享的作品（包括更早拍的）都不會帶浮水印。沒有訂閱時，這個開關顯示為開，想關掉會打開訂閱畫面，浮水印不會被關掉。訂閱結束後，之後儲存或分享的作品（包括訂閱期間拍的）會再帶浮水印，你在「設定 › 浮水印」的選擇會保留，再次訂閱時沿用。已經存進「照片」或已經分享出去的檔案不會被改動。
  • 浮水印在你的 iPhone 上直接加進畫面，不會把你的照片或影片傳到任何地方。如果浮水印加不上去，這一次不會儲存也不會分享任何內容。

7. 位置資料的細節

  • 什麼時候定位：只有你開著 App、允許定位，而且相機已經允許時，App 才會定位。離開 App 就停止，並丟掉記憶體裡的位置。
  • 精確度：App 要求約 100 公尺等級的位置。你也可以在 iOS 選擇只給「概略位置」，App 會把它標成概略。
  • 哪些位置會被用：拍攝時，只用 60 秒內取得、誤差在 1000 公尺以內的位置。不符合的話，這張照片或影片就不會有地點。
  • 存了什麼：每個項目的紀錄會存緯度、經度、高度（垂直精確度有效時）、水平精確度、時間、城市和行政區名稱，以及是否為概略位置。座標以完整精確度保存，App 畫面上只顯示較短的位數。
  • 存在哪裡：（1）你 iPhone 裡 Cam2gether 的紀錄。（2）你把項目存進「照片」時，位置（座標、水平精確度、時間）會寫進「照片」裡那一筆資料，前提是定位權限仍然允許。城市和行政區名稱只存在 Cam2gether 的紀錄，不會寫進「照片」。
  • 不寫進檔案：Cam2gether 不會自己把位置寫進照片或影片的檔案。
  • 在 App 裡顯示：媒體庫可以依地點分組，單一項目的「媒體資訊」會顯示地名或座標。這些畫面只在你的 iPhone 上。
  • 傳給 Apple：換成城市名稱需要 Apple 的地理編碼服務，見第 4 節。
  • 關閉權限：你關閉定位後，App 會立刻停止定位，並丟掉記憶體裡的位置。但已經存在項目紀錄裡的位置不會被自動清除。要刪除那個項目，位置才會一起刪掉。目前沒有「只移除位置」的功能。已存進「照片」的副本，它的位置要到「照片」App 裡處理。

8. 兒童

  • Cam2gether 不是專為兒童設計的 App，沒有針對兒童的功能，也不在 Apple 的兒童類別。
  • App 本身不蒐集任何人的個人資料，也不會詢問年齡。
  • 如果有人（包括兒童）自己寫信給開發者，開發者會收到那封信的內容，處理方式見第 10 節。家長或監護人可以隨時來信要求刪除。
  • App 裡的購買由 Apple 處理，開發者不會收到付款資料。家長若要限制購買，可以使用 iPhone 上 Apple 提供的控制，例如「螢幕使用時間」。
  • 如果家長或監護人有疑慮，也可以依第 3 節刪除 App 裡的內容，或到 iPhone 的「設定」關閉 App 的相機等權限。

9. 政策變更

如果 App 處理資料的方式改變（例如調整訂閱方案，或新增會用到資料的功能），開發者會更新這個網頁，並改上方的「最後更新」日期。請不定期回來看看。
