Critter Logic — Privacy Policy

Last updated: November 12, 2026

This policy covers Critter Logic, the daily logic puzzle app for Android published by Kallistesoft. In short: there is no account and we collect no personal information ourselves. Ads are served by Google AdMob, optional purchases ("No ads" and coin packs) go through Google Play, and the app uses Firebase to check for updates, report crashes, measure usage and run the shared leaderboards. This page explains what each of them processes.

1. Data kept on your device

Your daily results and times, streak, levels, coins and free hints, critter album and capsules, daily gifts, trophies, weekly event progress, the Worlds and hats you own or wear, puzzles in progress, settings (sound, music, reminder, language) and whether you bought "No ads" are stored on your device. Apart from the times and records that make the leaderboards (section 9), they are not sent to us. They are deleted if you uninstall the app or clear its data.

2. Advertising (Google AdMob)

Critter Logic shows ads served by Google AdMob (Google Mobile Ads SDK): a full-screen ad between puzzles (never during play), optional videos you can choose to watch for a hint, coins, an extra capsule, a doubled daily gift or to repair a streak, and a banner at the bottom of the screen. Ads for alcohol, gambling, dating and sexual content are blocked.

To show and measure ads and to prevent fraud, Google may collect:

This processing is Google's responsibility. See how Google uses information from sites or apps that use its services and Google's Privacy Policy.

3. Your choices and consent

Where the law requires it (European Economic Area, United Kingdom, Switzerland and some US states), Google's consent platform asks for your consent at launch. You can change your choices at any time with "Privacy options" in the app. On Android, you can also reset or delete your advertising ID in the device settings (Google › Ads).

4. Purchases (Google Play)

Critter Logic offers two kinds of optional in-app purchases: "No ads", a one-time purchase that removes the ads, and coin packs, which can be bought again (consumables). Both are processed entirely by Google Play under Google's Privacy Policy. We never receive your payment details (card number, billing address). The app only learns which product was bought and the purchase identifier Google Play gives it: "No ads" is recorded on your device, and the coins of a pack are credited on your device (the purchase identifier is kept there so a pack is never credited twice). We do not run a server that stores your purchases. Coins, and everything you get with them in the shop (capsules, Worlds, hats, streak repairs), stay on your device and have no cash value.

5. Lucky Nest

The Lucky Nest is an egg draw inside the game: one free egg a day, and more eggs paid with the game's coins. Each egg gives a random reward (coins, a free hint, a capsule, a golden capsule, or a feather that gives nothing), and the odds of each reward are shown in the app. The draw happens on your device. It is not real-money gambling: eggs cannot be bought with money directly, and rewards have no cash value and cannot be exchanged, sold or withdrawn.

6. App settings and updates (Firebase Remote Config, Google Play)

At launch, Critter Logic reads its settings (for example whether an update is required, how often ads may appear, shop prices, the Lucky Nest odds, or the daily gifts and weekly events) through Firebase Remote Config, and may open Google Play's update screen. This request carries a Firebase installation ID (random, unique to each install, separate from the advertising ID and not linked to your identity) and your IP address. This data is used only to run the app.

7. Crash reports (Firebase Crashlytics)

If Critter Logic crashes, Firebase Crashlytics sends us a crash report: the error and where it happened in the code, the app version, device model and operating system version, a Firebase installation ID (random, not linked to your identity) and your IP address. We use these reports only to find and fix bugs. They contain nothing that identifies you.

8. Usage statistics (Google Analytics for Firebase)

Critter Logic uses Google Analytics for Firebase to understand how the app is used (which puzzles are played and finished, hints used, sessions, retention) and how much its ads earn. Analytics records your interactions with the app and automatically collected events such as the first launch, ad impressions (with the revenue they bring in) and in-app purchases, as well as game events such as shop purchases with coins, Lucky Nest draws, and gifts, trophies and event prizes claimed. These events are linked to a Firebase app instance ID and a Firebase installation ID (random, not linked to your name or email). Analytics also collects device information (model, operating system version, app version, language), an approximate location (country or region) derived from your IP address and, when your consent choices and device settings allow it, your advertising ID.

Where consent is required, your answer in the consent form is passed to Analytics through Google consent mode: if you refuse, Analytics does not use your advertising ID or store identifiers for advertising and analytics, and sends only limited, cookieless signals. This data is processed by Google, is not sold, and we use it only in aggregate. User-level data is kept by Google for 2 months, then deleted. See Privacy and Security in Firebase.

9. Leaderboards (Firebase)

When you solve a daily puzzle for the first time, the app stores your time in Firebase Cloud Firestore together with a random anonymous ID created by Firebase Authentication, so you can see your rank and how you compare with other players. The app also stores your best streak and the number of dailies you have solved, for the all-time boards. There is no name, email or account, and other players see only the numbers, never your ID.

To keep fake times out, Firebase App Check asks Google Play Integrity to confirm that requests come from the genuine app installed from Google Play; this check is processed by Google. Leaderboard entries are kept so the boards can be shown. Uninstalling the app or clearing its data gives you a new anonymous ID; to have a stored entry deleted, contact us (section 14).

10. Daily reminder and language

If you turn on the optional daily reminder, the app asks for permission to show notifications and plans them on your device. Nothing is sent to us or to a server for this. The language you choose in the settings (English, French, Spanish, or your phone's language) is also stored only on your device.

11. Sharing results

When you tap "Share", the app prepares a short text (your daily times and streak) and opens your device's share menu. Nothing is sent without your action, and you choose who receives it.

12. Children

Critter Logic is family-friendly but intended for a general audience, not directed at children under 13. We do not knowingly collect personal information from children. Purchases ("No ads" and coin packs) are protected by a grown-up check in the app and by Google Play's purchase authentication, and parents can also require approval for purchases in Google Play's settings. If you believe a child has sent us information, contact us and we will delete it.

13. Your rights

Depending on where you live (including Québec under the Act respecting the protection of personal information in the private sector, elsewhere in Canada, and the European Union), you can ask to access, correct or delete your information, and withdraw your consent. Since we keep no data about you beyond anonymous leaderboard entries and our email exchanges, most such requests concern Google for advertising, purchases and Firebase; we'll gladly help you make them.

14. Contact and person in charge of the protection of personal information

For any question, request or complaint about your personal information: contact@kallistesoft.ca. If you write to us, we use your email address only to reply, and delete the exchange once it is no longer needed. You may also contact the Commission d'accès à l'information du Québec or the Office of the Privacy Commissioner of Canada.

15. Changes

We will update this page if Critter Logic's practices change. The date at the top shows the latest revision. Policies for Kallistesoft's other apps and website: kallistesoft.ca/en/privacy.
