Privacy Policy — BoomLine

Effective date: September 14, 2026 Last updated: October 16, 2026

BoomLine ("the Game") respects your privacy. This policy explains what information the Game collects and how it is used.

1. Developer

2. Information We Collect

2-1. Stored on your device only (never transmitted)

The following is stored solely on your device and is not sent to the developer or anyone else. It is removed when you uninstall the Game.

• Game progress (stages cleared, stars earned, best scores, attempt counts)
• In-game currency state (hearts, coins, and refill timestamps)
• Settings (language, theme, font, sound set, effect options)
• Nickname you typed and profile image you selected
• Tutorial completion flags

2-2. Sent to the developer (play statistics)

To tune the Game we send the following play statistics to the developer's storage (Google Firebase, servers operated by Google LLC). Nothing in it identifies you.

• What happened: stage start, clear, fail, quit; heart spend and heart empty; ad offer and ad watched; time pass sheet opened and purchased (product ID); tutorial viewed; setting changed
• Its numbers: stage number and track, shots used, stars, time taken, catch count, hearts left, minutes since launch
• App version, platform name (e.g. Android), timestamp
• Install identifier: a random 16-character value generated by the app. It is unrelated to the advertising ID, device ID or any account, and is regenerated when you Reset the Game
• Session identifier: a random value created on each launch

Not sent: nickname or profile image, device model, advertising identifier, location, contacts, or anything listed in 2-4. Statistics are sent in batches when a connection is available and are accessible only to the developer.

2-3. Information collected by third-party services

The Game uses the following two third-party services. It uses no other account sign-in services.

Google AdMob (rewarded and interstitial ads) — rewarded ads play only when you choose "watch an ad for hearts." From 22 October 2026, interstitial ads may appear between stages in some countries. The ads SDK initializes at app start after you consent and may collect and transmit: - Advertising identifier (Android Advertising ID), device information (model, OS version, language and country), ad impression and click records - In regions that require it (EU/EEA, UK, etc.) a consent form (UMP) is shown on first launch; declining does not limit the Game.

Google Play Billing (time pass purchases) — payment details (card numbers, etc.) are handled by Google directly and the Game never accesses them. The Game receives only the purchased product ID and purchase token, which are stored on your device only.

If we later adopt crash reporting (Firebase Crashlytics) or Google Play Games Services, we will update this policy and the Google Play "Data safety" section before releasing that version.

2-4. What we do not collect

• Name, date of birth, gender, address, phone number, or other identity data
• Contacts, photos, precise location, call logs, or files
• Camera or microphone access

(When you pick a profile image, only that single image is copied into the app's private storage; the Game does not access your photo library as a whole.)

3. How Information Is Used

• Saving and restoring game progress
• Keeping your settings
• Serving ads — rewarded ads (only when you choose to watch one) and interstitial ads in some countries
• Saving and restoring your time pass purchase state
• Analyzing play statistics — which stages are too hard, whether hearts, ads and time passes are balanced (never to identify individual users)

Information is not used for any other purpose, and no analysis is performed to identify individual users.

4. Retention and Deletion

• Device-stored data is deleted when you uninstall the Game.
• You can delete your progress yourself in-game via Settings → Reset.
• Play statistics sent to the developer are deleted two years after collection.
• Data collected by third-party services (Google AdMob, Google Play Billing) is retained and deleted under their own policies.

5. Third Parties

We do not sell or rent your information. The following providers process data to deliver the service:

6. Your Rights

• Delete game data: In-game, go to Settings → Reset. Uninstalling the Game also removes all device-stored data.
• Opt out of personalized ads: Device Settings → Google → Ads → "Opt out of Ads Personalization."
• Access, correction, or deletion requests: Contact us at the email above and we will respond within the period required by applicable law.
• Play statistics sent to the developer cannot be linked to a person and are therefore not subject to individual access or deletion (the install identifier is a random value generated by the app and is regenerated on Reset).

7. Children's Privacy

The Game is intended for users aged 13 and over. It is not directed to children under 13, and we do not knowingly collect personal information from them. If we learn that we have collected such information, we will delete it promptly. Parents or guardians who believe this has occurred may contact us at the email above.

8. Security

• Device-stored data lives in the app's private storage and is not accessible to other apps.
• The developer does not hold information that personally identifies you.
• Communication with third-party services uses encrypted (HTTPS) channels.

9. Changes to This Policy

If this policy changes, we will post the updated version on this page and revise the "Last updated" date. Significant changes will also be announced in-game or in the store release notes.
