Privacy Policy

Effective date: 2026-10-02

Overview

OJO is a "spot the differences" puzzle game published on Google Play (Android), on the web, and as a Facebook Instant Game. The developer runs no backend server and operates no account system: there is no sign-up, no login, and no user profile. This policy describes how your data is handled when you play, on every one of those platforms.

Developer: Spektrum Games. Contact: spektrumyazilim@gmail.com.

Data We Collect and Store

Game State

Your game progress, per-level best completion times, number of incorrect taps, selected language preference, tutorial acknowledgment, home-screen-shortcut prompt history, and session counter are stored only on your own device or in your own platform account storage:

• Android (Google Play) — stored on the device through Capacitor Preferences (the app's private storage area). This data never leaves your phone and is not tied to any account.
• Web — stored in your browser's local storage.
• Facebook Instant Games — stored through Facebook Instant Games player storage, which is Meta's infrastructure tied to your Facebook account.

You control this data: see Data Deletion below.

Analytics

We collect gameplay events to understand how the game is played. On Android these events are sent to Google Firebase Analytics; in the Facebook Instant version they are sent to Facebook Analytics via `FBInstant.logEvent`. The web build logs nothing.

The complete list of events the game sends:

• `level_start` — a puzzle was opened (puzzle ID)
• `level_complete` — a puzzle was finished (puzzle ID, elapsed time in milliseconds, number of incorrect taps)
• `ad_offer` — the optional reveal offer was shown (whether it was rewarded, skipped, dismissed or unavailable)
• `ad_hint` — a rewarded hint was requested (result, puzzle ID)
• `ad_error` — an ad failed to load or show (slot name, phase, error code)
• `share_open` / `share_done` — a challenge or invite share was started/completed (which action)
• `shortcut_prompt` — result of the add-to-home-screen prompt
• `onboarding_done` — the tutorial was completed
• `entry_social` — the game was opened from a shared challenge or invite (kind, puzzle ID)
• `app_error` — an unexpected runtime error (first 100 characters of the error message)

These events describe app interactions only. They contain no name, no email address, no contact data and no precise location. Firebase Analytics additionally collects standard technical data (device model, operating system version, country derived from IP address, and an app instance identifier) as described in Google's policies: https://firebase.google.com/support/privacy and https://policies.google.com/privacy

Personal Information We Do Not Collect

The game does not access, request or transmit:

• Your name or profile photo
• Your friend list or contacts
• Your email address or phone number
• Your precise location
• Your camera, microphone, photos or files

The Android app declares no runtime permissions beyond internet access and the advertising identifier described below.

Advertising

The Android version shows Google AdMob rewarded video ads only. Ads are always player-initiated: you tap a button to watch a video in exchange for a gameplay benefit (a revealed difference or a hint). There are no mandatory, interstitial or banner ads, and no ad is ever shown without your tap.

• The Android app declares the `com.google.android.gms.permission.AD_ID` permission, which lets Google AdMob read the device advertising ID. Google uses that identifier to serve and measure ads. You can reset or delete it at any time in Android Settings → Privacy → Ads.
• Before any ad is requested, the app shows Google's UMP (User Messaging Platform) consent form where required by law (for example in the EEA and the UK). Whether ads are personalised depends on the choice you make in that form; you can change it later from the game's settings if the form is available in your region.
• Ad serving and ad-related data collection are governed by Google's policies: https://policies.google.com/technologies/ads

The Facebook Instant version uses Meta Audience Network rewarded video ads under the same player-initiated rule; that data is governed by Meta's privacy policy at https://www.facebook.com/privacy/policy/ . The web version shows no ads.

Data Sharing

We do not sell your data and we do not share it with anyone except the service providers named above:

• Google (Firebase Analytics) — app interaction events and standard technical data, on Android.
• Google (AdMob) — the advertising identifier and ad-request data, on Android.
• Meta — player storage, analytics and ad data, in the Facebook Instant version only.

Sharing and Inviting

When you tap "Challenge a friend" or "Invite friends," a dialog provided by the operating system (Android share sheet) or by Facebook appears. You choose the recipients. OJO does not see the recipient list, does not send messages on your behalf, and does not collect contact information.

Children

OJO is not directed to children under 13. We do not knowingly collect data from children under 13. In the European Economic Area (EEA) and the United Kingdom, the minimum age is 16 where local law requires it. If you believe a child has provided data to us, contact spektrumyazilim@gmail.com and we will delete it.

Data Deletion

You have the right to delete your game data.

• Android — uninstalling the app deletes all locally stored game data (progress, times, language preference, prompt history). You can also clear it without uninstalling through Android Settings → Apps → OJO → Storage → Clear data. To reset the advertising identifier used by ads, use Android Settings → Privacy → Ads.
• Web — clear your browser's local storage (Settings → Privacy → Clear browsing data).
• Facebook Instant — removing OJO at https://www.facebook.com/settings/apps_and_websites/ deletes all Instant Games player storage data associated with the game.

For any other data deletion request or question, contact spektrumyazilim@gmail.com. We will respond within 30 days.

Changes to This Policy

We may update this policy from time to time. We will notify you of material changes by updating the Effective date above. Continued use of the game after changes indicates your acceptance of the new policy.
