Privacy Policy

Last updated: 1 de septiembre de 2026

Múltiplo is a mental-arithmetic game developed by Jose Luis Querido Chica. This policy explains what data the app handles and what happens to it. The short version: the app has no servers of its own and your game data never leaves your device.

1. Data stored on your device

Múltiplo stores the following in local device storage, and nowhere else:

Your game progress: levels cleared, stars, scores, best times, daily streak, coins and power-ups.
The player profiles you create: the name you type and, if you pick one, a profile picture.
Your preferences: sound, haptics, difficulty, theme, language and the reminder time.

None of this is sent to any server of ours, because we do not have one. It is deleted entirely when you uninstall the app, and profiles can be deleted individually from Settings.

2. Profile picture

You can pick a photo from your library or take one with the camera to use as an avatar. That image is stored only on your device, inside the app's data. It is not uploaded anywhere, not shared and not used for anything else. The app only requests camera access at the moment you tap "Take photo", and you can revoke it at any time in iOS Settings.

3. Game Center (optional)

If you are signed in to Game Center, the app submits your Classic, Sprint and Daily Challenge scores to Apple's leaderboards so you can compare yourself with other players. That processing is carried out by Apple under its own privacy policy. If you do not use Game Center, the app works the same and nothing is submitted.

4. Notifications

You can enable a daily reminder so you do not lose your streak. It is a local notification: your own device schedules it at the time you choose. There is no notification server and no identifier is registered.

5. Advertising (free version)

The free version of Múltiplo shows Google AdMob ads. To serve them, Google may process your device identifiers and data about your interaction with the ads. Before loading any ad, the app asks whether you accept personalized ads or prefer non-personalized ads only, and you can change that choice at any time in Settings → Ads & privacy.

Google's processing is governed by its own privacy policy: https://policies.google.com/privacy

If you buy the app, advertising is removed permanently and no ad SDK is loaded.

6. Purchases

In-app purchases are handled by Apple through the App Store. We never receive or store your payment details.

7. What we do NOT do

We do not sell or share your data.
We do not use our own analytics or tracking tools.
We do not build advertising profiles from your game progress.
We do not ask for or store your email, phone number or location.
There are no user accounts and no passwords.

8. Children

Múltiplo is an arithmetic game suitable for all audiences and children do use it. We do not knowingly collect personal data from any user, regardless of age. If you are a parent or guardian and believe your child has entered data you want removed (a name or a profile picture, for example), simply delete that profile from Settings or uninstall the app.

9. Your rights

Because all data lives on your device and under your control, you can exercise your rights directly:

Access and rectification: everything stored is visible and editable in the app.
Erasure: delete the profile from Settings, or uninstall the app to remove everything.
Objection to personalized advertising: change your choice in Settings → Ads & privacy, or buy the app to remove ads.

10. Changes to this policy

If the policy changes, the date in the header and the version shown in the app will be updated. Significant changes will be announced inside the app.
