Overview
Liquid Sort ("the App") is a color-sorting puzzle game published by Oswald Stack ("we", "us"). This policy explains what information the App collects, how it is used, and the choices you have. We built Liquid Sort to work without requiring an account, email address, or any personal profile — you can play the entire game without ever giving us your name or contact details.
Information we do not collect
The App does not require registration and does not collect:
- Your name, email address, or phone number
- Precise or coarse location
- Photos, camera, or microphone access
- Contacts or files on your device
- Payment information (the App has no in-app purchases)
Information stored on your device
Your game progress — coins, unlocked levels, star ratings, and sound preferences — is saved locally on your device only. It is never transmitted to us or any server. Uninstalling the App or clearing its storage permanently deletes this data.
Information collected automatically
Like most mobile apps, Liquid Sort uses third-party services that may collect device and usage information to operate advertising and measure engagement. This data is tied to device/advertising identifiers, not to your real-world identity.
| Service | What it collects | Purpose |
|---|---|---|
| Google AdMob | Advertising ID, device/network info, ad interaction data | Shows the optional rewarded video ads you choose to watch for in-game bonuses (coins, extra moves, hints) |
| Google Firebase Analytics | App usage events (levels played, session length, feature usage), device type, approximate region | Helps us understand which levels are too hard or too easy and improve the game |
These providers may combine this information with data from other apps in accordance with their own privacy policies: Google Privacy Policy · How Google uses ad data · Firebase Privacy & Security
Advertising
Liquid Sort contains the following types of ads, all served by Google AdMob:
- Rewarded video — optional ads you choose to watch in exchange for an in-game bonus (extra coins, extra moves, or a hint). You can play indefinitely without ever watching one.
- Interstitial — a brief full-screen ad shown automatically between levels at regular intervals (e.g. after every 5th completed level).
Your choices
- Opt out of personalized ads: on Android, go to Settings → Privacy → Ads, and turn on "Opt out of Ads Personalization." On iOS, go to Settings → Privacy & Security → Tracking, and disable tracking for the App.
- Reset your advertising ID at any time from your device's ad settings.
- Delete all local data: uninstall the App, or clear its storage from your device's App Info settings.
Children's privacy
Liquid Sort is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us using the details below so we can remove it.
Data retention
Locally stored game progress remains on your device until you delete the App. Analytics and advertising data collected by Google are retained according to Google's own retention schedules, described in the links above.
Changes to this policy
We may update this policy as the App evolves. Material changes will be reflected by updating the effective date at the top of this page. Continued use of the App after changes are posted constitutes acceptance of the updated policy.
