一句話說明

「腦力小零食」（英文名 Tile Snack）不需要註冊，不收你的姓名、電話、Email、照片或位置；你沒有允許的話，也不會跨 App 追蹤你。我們只收匿名的使用數據，用來知道哪一關太難、哪裡看不懂、有沒有閃退，好把遊戲改得更好玩。遊戲裡有廣告：你自己按「看廣告」領獎勵，以及第 11 關以後每過 3 關播一次。

1. 存在你手機裡的資料

遊戲進度（玩到第幾關、道具數量、集點卡、聲音開關等設定）只存在你的手機裡，不會上傳。刪除 App 就會一起刪掉。

2. 我們收集的匿名使用數據

• 你怎麼玩：打開 App、開始一關、過關、失敗、玩到一半離開、使用或領取道具、開大禮包、磁鐵、有沒有看廣告、按分享。

• 手機資訊：App 版本、手機系統和版本、手機的語言和時區。

• 錯誤紀錄：App 出錯或閃退時的錯誤訊息。

每支手機第一次打開時，會隨機產生一組代號，用來分辨「是不是同一支手機隔天又回來玩」。這組代號跟你的姓名、電話、Email、Apple 帳號都沒有關聯，我們無法從它知道你是誰。我們的數據服務設定成不保存你的 IP 位址，也不用 IP 推算你在哪裡。

3. 你主動送出的意見

在「有問題跟我說」寫下並送出的文字，會連同上面的匿名代號和目前關卡一起送給我們。請不要在裡面寫姓名、電話、地址等個人資料。

4. 廣告

遊戲裡的廣告由 Google AdMob 播放，有兩種：你自己按「看廣告」領獎勵（格子滿了多 1 格、道具補充、開大禮包、磁鐵、道具袋升級禮包），不看也可以繼續玩；以及第 11 關以後，每過 3 關在換關時播一段，幾秒後可以關掉。

大禮包的倍數是隨機的，每種倍數的機率在你看廣告之前就會顯示在畫面上。遊戲裡沒有任何付費項目。

第一次打開 App 時，手機會問你「是否允許追蹤」。允許的話，Google 會用廣告識別碼（IDFA）播比較符合你興趣的廣告；不允許的話，播的是一般廣告，遊戲功能完全一樣。之後可以在 iPhone 的「設定 → 隱私權與安全性 → 追蹤」隨時更改。廣告內容限制在普遍級和保護級（PG）。

為了播放廣告、計算成效和防止作弊，Google 可能會收集裝置和系統資訊、IP 位址（可以推算大概的地區）、廣告的播放和點擊紀錄，以及（你允許追蹤時）廣告識別碼。Google 怎麼使用這些資料，請看 Google 隱私權政策：https://policies.google.com/privacy

5. 我們不收集的東西

姓名、電話、Email、通訊錄、照片、相機、麥克風、位置。廣告識別碼只有在你允許追蹤時，由 Google 廣告使用，我們自己不讀取也不保存。我們不賣也不出租任何資料給別人。

6. 誰會處理這些資料

匿名使用數據和意見存放在 PostHog（posthog.com）提供的數據服務，伺服器位於美國。PostHog 只依照我們的指示保存和處理資料。

廣告由 Google AdMob 提供，Google 依它自己的隱私權政策處理廣告相關資料。

7. 保存多久

匿名使用數據和意見最多保存 2 年，之後刪除。

8. 你可以怎麼做

• 刪除 App：手機裡的遊戲進度和匿名代號會一起刪掉。重新安裝會產生新的代號，舊的數據無法再對應到你。

• 想刪除你送出過的意見，或有任何疑問：請用 App 首頁的「有問題跟我說」告訴我們，或寫信到 tilesnack.app@gmail.com，並說明大約是哪一天送出的。

9. 健康小知識和小動作

App 裡的健康小知識和小動作只是一般的生活提醒，不是醫療建議，也不能取代醫師或專業人員的意見。做動作時身體不舒服請馬上停下來，有疑問請請教醫師。

10. 兒童

本 App 適合所有年齡，但不是專為兒童設計；我們不會刻意收集兒童的個人資料。

11. 政策更新

這份政策更新時，會修改最上面的日期；有重大變更時，會在 App 裡告訴你。

12. 聯絡我們

開發者：與 App Store 上「腦力小零食」的開發者相同。有任何問題，請用 App 首頁的「有問題跟我說」聯絡我們，或寫信到 tilesnack.app@gmail.com。

In short

Tile Snack (Chinese name 腦力小零食) needs no sign-up. We do not collect your name, phone number, email, photos or location, and we do not track you across apps unless you allow it. We only collect anonymous usage data to learn which levels are too hard, what is confusing and whether the app crashes, so we can make the game better. The game shows ads: rewarded ads that you choose to watch, and from level 11 one ad every 3 levels.

1. Data stored on your phone

Your game progress (level, tools, stamp card, and settings such as sound) is stored only on your phone and is never uploaded. Deleting the app deletes it.

2. Anonymous usage data we collect

• How you play: opening the app, starting, clearing, failing or leaving a level, using or claiming tools, opening gift packs, the magnet, whether you watched an ad, and tapping share.

• Device info: app version, operating system and version, phone language and time zone.

• Error logs: error messages when the app has a problem or crashes.

When the app is first opened, it creates a random ID so we can tell whether the same phone comes back the next day. This ID is not linked to your name, phone number, email or Apple Account, and we cannot tell who you are from it. Our analytics service is set to not store your IP address and not to estimate your location from it.

3. Feedback you send

Text you write and send in "Feedback" is sent to us together with the anonymous ID above and your current level. Please do not include personal details such as your name, phone number or address.

4. Ads

Ads are served by Google AdMob in two ways: rewarded ads that you choose to watch for a reward (an extra tray slot, tool refills, gift packs, the magnet, tool bag upgrade packs) — you can always keep playing without them; and, from level 11, one ad between levels every 3 levels, which can be closed after a few seconds.

Gift pack multipliers are random, and the odds of each multiplier are shown on screen before you watch the ad. There are no in-app purchases.

The first time you open the app, your phone asks whether to allow tracking. If you allow it, Google uses the advertising identifier (IDFA) to show ads that better match your interests; if not, you see general ads and the game works exactly the same. You can change this anytime in iPhone Settings → Privacy & Security → Tracking. Ad content is limited to G and PG ratings.

To serve ads, measure them and prevent fraud, Google may collect device and system information, your IP address (which can indicate your approximate region), ad views and clicks, and — if you allow tracking — the advertising identifier. See Google's Privacy Policy for how Google uses this data: https://policies.google.com/privacy

5. What we do not collect

Name, phone number, email, contacts, photos, camera, microphone or location. The advertising identifier is used only by Google ads, and only if you allow tracking; we never read or store it. We do not sell or rent any data to anyone.

6. Who processes the data

Anonymous usage data and feedback are stored with PostHog (posthog.com), an analytics service with servers in the United States. PostHog stores and processes the data only on our instructions.

Ads are provided by Google AdMob, which handles ad-related data under its own privacy policy.

7. How long we keep data

Anonymous usage data and feedback are kept for at most 2 years and then deleted.

8. Your choices

• Delete the app: your game progress and anonymous ID are deleted with it. Reinstalling creates a new ID, and old data can no longer be matched to you.

• To delete feedback you sent, or for any question: tell us through "Feedback" on the app's home screen, or email tilesnack.app@gmail.com, and mention roughly when you sent it.

9. Health tips and stretches

The health tips and small stretches in the app are general lifestyle reminders, not medical advice, and they do not replace a doctor or other professional. Stop right away if anything feels uncomfortable, and ask your doctor if you have questions.

10. Children

The app is suitable for all ages but is not designed for children, and we do not knowingly collect personal information from children.

11. Changes to this policy

When this policy changes, we update the date at the top; for major changes we will let you know in the app.
