Privacy Policy — LinkFlow

Effective date: 9 September 2026

LinkFlow (“the app”) is a flow-connection puzzle game, published by Aztra Global. This policy covers the Android app distributed on Google Play under the package name com.wrenfield.linkflow6142. It explains what the app collects, why, and what it does not collect.

The short version

The app has no accounts and no sign-in. We never ask for your name, email address, phone number or postal address.
Your progress stays on your device only.
The app does include analytics and attribution SDKs that report a device identifier. That is the only category of personal data that leaves your device.

Collected and shared with third parties

Device and app identifiers. The app bundles the AppsFlyer and Adjust measurement SDKs and Firebase Cloud Messaging. Together they collect and transmit:

AppsFlyer — Google Advertising ID, install referrer, app open and session events
Adjust — Google Advertising ID, app open and session events
Firebase Cloud Messaging — a push registration token, device model, operating system version

These are used to measure where installations come from and how many people open the app, and to deliver notifications. They are not used to build an advertising profile about you inside the app, and the app shows no advertisements. The app declares the com.google.android.gms.permission.AD_ID permission for this purpose.

Network requests. When the app starts it requests its configuration from our server. The request carries the platform name, the application identifier and your device’s time zone name (for example Asia/Manila). As with any internet request, our server also receives the originating IP address. We use it to determine the country the request came from. We do not store it as part of a user profile and we do not use it to locate you more precisely than country level.

Not collected

Name · Email address · Phone number · Postal address · Photos · Videos · Files · Contacts · Calendar · Precise location (GPS) · Health data · Financial information · Messages · Audio recordings · Web browsing history · List of installed apps.

The app requests only the INTERNET permission in its own manifest. It has no camera, microphone, location, contacts or storage permissions. There is no sign-up, no login, no advertising placement and no in-app purchase.

Stored only on your device

The app saves your progress in each difficulty tier, using Android's standard app-preferences storage: linkflow_solved_<tier> (puzzles solved in that tier) and linkflow_level_<tier> (which level you are on), where <tier> is one of normal, hard, expert, master — eight integers in total.

They are never uploaded, never attached to analytics events, and never sent to our server. Uninstalling the app deletes them.

Sharing

We share the identifiers listed above with AppsFlyer, Adjust and Google, acting as our data processors for attribution and messaging. We do not sell your data. Each processes the data it receives under its own privacy policy:

Security

All network traffic uses HTTPS.

Children

The app is not directed at children under 13 and we do not knowingly collect data from them.

Your choices

Advertising ID: reset it, or opt out of ad personalisation, in Android Settings › Privacy › Ads.
Notifications: decline the permission prompt, or turn notifications off later in Android Settings › Apps › LinkFlow. The app works either way.
You can delete everything the app stores locally by uninstalling it, or via Android Settings › Apps › LinkFlow › Storage › Clear data.
To request deletion of data held by us or our processors, email the address below and include the approximate date of installation.

Changes to this policy

If this policy changes we will update the effective date above and publish the new version at this same URL.
