Effective date: August 23, 2026  ·  Applies to: the Crossly Android app (package er.prateek.crossly) distributed on Google Play
Playing on another platform?

This policy explains what information the Crossly Android app collects, why, and what choices you have. It's written to be read, not just posted in an app store field — if anything is unclear, email us and we'll fix the wording.

1. Who we are

Crossly is developed and operated by Prateek Gaur, an individual developer ("we", "us"). For the purposes of the EU/UK General Data Protection Regulation (GDPR) and similar laws, we are the data controller for the information described below.

Contact for any privacy question or request: [email protected]

2. Who this app is for

Crossly is a general-audience crossword puzzle game and is listed on Google Play as such. It is not directed at children under 13, and we do not knowingly collect personal information from children. Advertising in this app is served in standard (not child-directed) mode. If you believe a child has provided us information, contact us and we will delete it.

3. Information we collect

3.1 Information you choose to provide

3.2 Information collected automatically, on your device

3.3 Challenge and share links

When you share the app or challenge a friend, Crossly builds a link that encodes your display name, a puzzle identifier, and your time — entirely on your device. That link is never sent to or stored on any server we operate; it is decoded directly on the recipient's device when opened. We have no record of who you challenged or who accepted.

3.4 Information collected by third-party services we use

ServicePurposeWhat it may collect
Google Firebase Analytics Understand feature usage and app performance (screen views, puzzle completions, settings changes, ad and purchase-funnel interactions) Pseudonymous analytics/app-instance identifiers, device model, OS version, coarse (region-level) location, app version, event data listed above
Google Firebase Crashlytics Detect and diagnose crashes Crash logs, stack traces, device model, OS version, app version
Google Firebase Remote Config Deliver configuration values (feature toggles, ad settings) without a new app release A pseudonymous app-instance identifier used to resolve the config; no content you type is sent
Google AdMob Serve advertising that funds free access to Crossly Your Android Advertising ID (unless limited/reset in your device settings), approximate location, device information, and — unless you've opted out per §6 — data used to personalize ads
Google Play Billing (only if/when a paid "remove ads" option is offered) Process in-app purchases Purchase and entitlement status; full payment details are handled by Google Play and never reach us

Each provider is bound by its own privacy policy for how it independently processes data: Firebase Privacy & Security, AdMob & user data, and Google's overall Privacy Policy.

4. What we do not collect

5. Permissions this app requests

Crossly requests Internet access only, to load puzzle content, sync progress-related config, show ads, and send analytics/crash data described above. It does not request any dangerous/runtime Android permission (no location, camera, microphone, contacts, storage, etc.).

6. Advertising and your choices

Google AdMob may use your Advertising ID and device information to show ads and measure their performance, and may personalize ads based on your activity unless you opt out. You can:

7. Data retention

Data stored locally on your device (progress, settings, install identifier) persists until you clear the app's data or uninstall it. Analytics, crash, and advertising data are retained by Google per their own retention schedules, which we do not control.

8. Data sharing and disclosure

We do not sell personal information. We share data only with the service providers listed in §3.4, to the extent necessary for them to provide analytics, crash reporting, and advertising services, or where required by law, to protect our legal rights, or to investigate fraud or abuse of the service.

9. International data transfers

Our third-party providers (Google) operate global infrastructure, which means data may be processed in countries other than your own, including the United States. Google maintains its own safeguards (including EU Standard Contractual Clauses where applicable) for these transfers.

10. Your privacy rights

If you are in the EEA, UK, or Switzerland (GDPR)

You have the right to access, correct, delete, restrict, or port your personal data, and to object to its processing. Because Crossly stores gameplay data locally and keeps almost no data on our own servers, most of these rights are exercised simply by clearing the app's data or uninstalling it. For anything held by our analytics/advertising/crash providers, contact us and we will help route the request, and you may also lodge a complaint with your local data protection authority.

If you are a California resident (CCPA/CPRA)

You have the right to know what personal information is collected, to request deletion, to correct inaccurate information, and to opt out of the "sale" or "sharing" of personal information for cross-context behavioral advertising. We do not sell personal information for money. To the extent ad personalization is considered "sharing" under CPRA, you can opt out using the tools in §6.

Everyone else

Regardless of where you live, you can always email us at [email protected] to ask what we hold about you or to request deletion, and we will respond within a reasonable time.

11. Security

We rely on the security practices of the third-party providers listed above for data they process, and standard transport security (HTTPS/TLS) for data in transit. No method of transmission or storage is 100% secure, but we do not operate a server-side database of user records that could itself be breached.

12. Changes to this policy

We may update this policy as the app changes. We'll update the effective date above; material changes will be reflected here before they take effect, and this policy is also linked from the app's Settings screen so it's always one tap away.
