Trazen privacy policy

Last updated: October 3, 2026

Trazen is a logic puzzle game for Android. This page explains, clearly and plainly, what information the app handles and how.

This is a translation for convenience. The Spanish version (Política de privacidad) is the original.

Quick summary

Trazen does not require sign-up or a user account, shows no ads and works offline. Your progress is saved on your own device and, if you have it turned on, in your phone’s backup. In the current version the app does not send usage information to any service; if we add usage analytics in the future, it will be optional and we will explain it to you first (see “Usage analytics”).

What is stored on your device

The app stores the following locally on your device (in the app’s own storage):

• Your level progress (which levels you have completed)
• Your best times and records
• Your streak of days played in the daily challenge
• The badges you have earned
• Your preferences (light/dark theme, sound, daily reminder on or off, and language)

Trazen has no accounts of its own and no servers where this data is kept.

Phone backup

If you have Android backup turned on (phone Settings → Google → Backup), the system itself includes this game data in it, in your Google account, so you can get it back if you switch phones or reinstall the app. That backup is made and stored by Android under Google’s privacy policy; the app does not connect to the internet to make it. If you don’t use backup, the data is deleted when you uninstall the app.

Usage analytics

The current version of Trazen does not include analytics tools. A future version may add usage analytics (for example, Google Analytics for Firebase) so we can learn which parts of the game are used most and improve it. If we do:

• It will be optional: the app will ask for your permission and you can play just the same if you say no
• You will be able to change your mind at any time from Más → Ajustes (More → Settings)
• It would use game usage data (for example, levels played or screens opened), never your name, email or contacts
• We will update this page before that version is released, stating what is collected, with which service and for how long

What the app does not do

• It does not require sign-up or an account, and it does not ask for data such as your name, email or phone number
• It does not show ads of any kind
• It does not sell your information to anyone
• It does not access your camera, location, contacts or any other sensitive device permission

Typeface

The app uses the Plus Jakarta Sans typeface, bundled inside the app itself. It is not loaded from external servers.

Device permissions

Trazen does not request any sensitive permission (no camera, location, contacts or files) and the game works offline.

The only permission it may ask for is notifications, for the daily challenge reminder (at 20:00, only if you have not played it yet that day). It is a local notification: your phone schedules it itself. You can turn it off in Más → Ajustes (More → Settings) or in your Android settings.

Voluntary contributions

From Más → “Apoya a Trazen” (More → Support Trazen) you can, if you wish, make a small contribution to help us keep developing the game. Choosing an amount opens Numik Labs’ Ko-fi page in your browser, outside the app: the payment and any data Ko-fi asks for are handled by Ko-fi under its own policy, not this one. Trazen does not receive or store your payment details, and contributing does not unlock anything or change the game.

External links

The app may open links outside of it: the rating button opens Trazen’s Google Play listing, the privacy link opens this page, the Instagram link opens our profile and “Apoya a Trazen” (Support Trazen) opens our Ko-fi page. Once you leave the app, those services’ policies apply (for example, Google’s privacy policy), not this one.

Children

Trazen does not ask anyone for personal data, regardless of their age, and does not require sign-up. If optional analytics is added in the future, it will not be used to build user profiles or to show advertising.

Changes to this policy

If this policy changes (for example, when usage analytics is added), this page will be updated with the revision date before the version of the app that includes the change is released.
