Chromilo privacy policy

Last updated: November 2, 2026

Chromilo is an Android puzzle game published by Spun Develop. Contact us about privacy at codelity@gmail.com. You do not need a Chromilo account to play.

Data on your device

The game stores puzzle and tutorial progress, visual settings, your Analytics choice and a previously verified ad-free status on your device. It has no cloud save. Puzzle layouts and saved progress are not uploaded to a Chromilo server. Android backup and transfer of this app data are disabled. Clearing app data or uninstalling the game removes local data; it does not erase data already processed by Google.

Optional usage analytics

Google Analytics for Firebase is off until you choose to allow it. You can decline and still play the full game, or change your choice in Settings at any time. Turning Analytics off stops future Analytics collection without waiting for a deletion request.

If you allow Analytics, the app sends events about levels, results, mistakes, retries, hints and the tutorial, with information such as board size and level number. Firebase also processes automatic usage events, an app-instance identifier, app/device information and approximate location. We use this information to understand and improve the game. We do not add names, email addresses, entered text, puzzle layouts or random seeds to these events.

Analytics advertising storage, advertising user data and advertising personalization remain disabled. Allowing Analytics does not enable personalized advertising. See Firebase privacy information.

Restricted advertising

Depending on the app version, advertising can appear in the menu or during gameplay as a Google AdMob banner in a dedicated area separate from the puzzle and its controls. At most one banner is displayed at a time. Chromilo requests no personalized advertising and applies the same protective treatment to everyone, with the maximum ad content rating set to G. The app does not ask for or record your age or date of birth, and does not request Android location permissions or the Android Advertising ID.

Advertising still involves data processing. Google Mobile Ads may collect and share an IP address (which can indicate approximate location), app/ad interactions, performance and diagnostic information, and supported app/device identifiers. Google uses this data for advertising, measurement and fraud prevention. Removing the Advertising ID and restricting ads do not eliminate all SDK data processing. Mobile Ads encrypts data in transit. See Google Mobile Ads data disclosure and Google's privacy policy.

Google's User Messaging Platform checks privacy status when the app starts. Chromilo requests under-age-of-consent protection for everyone as a processing rule, not as a measurement of your age. A consent form is generally not shown in this mode. Ads require a successful privacy update and permission from the SDK to request ads. Any privacy options required by the SDK are accessible in Settings.

Advertising and privacy-status requests are separate from optional Firebase Analytics. Declining Analytics does not switch off this restricted advertising. A verified ad-free purchase stops banner requests in both the menu and gameplay; it does not delete earlier advertising data. Google applies its own retention rules to advertising and privacy-status data; the Analytics retention period below does not apply to those records.

Purchases

Google Play handles the optional one-time purchase to remove ads. Chromilo receives product and purchase information to check, acknowledge and restore the entitlement. It does not receive payment-card details or send purchase records to a separate Chromilo server. A verified ad-free status is stored locally. Restoring a purchase does not start a new payment, and buying or restoring does not turn on Analytics. Google Play retains transaction records under its own terms and privacy policy.

Retention and privacy requests

Our Analytics property uses a two-month retention period for user-level and event-level data, without extending that period on new activity. Google removes data covered by this setting on its processing schedule; aggregated reports are outside this setting. See Google Analytics retention controls.

You may contact codelity@gmail.com to request access to or deletion of data associated with your use of Chromilo. Because there is no Chromilo account, an email address alone does not identify an Analytics installation. Settings → Privacy can show the Analytics app-instance ID while Analytics is enabled and the SDK can return it. You can copy the ID or prepare a request to review and send yourself. We may need this identifier to locate the relevant data.

You can turn Analytics off immediately. If you want to retain the identifier for a request, copy it beforehand; it may become unavailable after withdrawal, reset or uninstall. If the installation cannot be identified, we may be unable to locate its earlier Analytics records. The retention setting still applies to data it covers. Copying a request or opening an email draft does not send a message or delete data. Local deletion, uninstalling and buying ad-free do not erase Google's earlier records.

If you email us, we process your email address and message to respond. Please include only information needed for your request. You can also use Google's privacy controls for information Google processes under its own policies.

Versions and changes

Optional Analytics is available from version 0.1.1, and privacy request tools from 0.1.2. The restricted advertising described here is configured from version 0.1.6. Earlier versions without these features do not process data through them. Chromilo does not use Firebase Crashlytics. We will update this page when these practices change.
