Privacy Policy

1. Introduction

Numberwise ("the game") is a number-pairing puzzle published by Into Hash ("we," "our," or "us") for iOS and Android. You clear pairs of digits that are equal or add up to ten. This Privacy Policy explains what the game collects, what our service providers collect, and the choices you have.

The short version: there is no account and no login, your progress lives on your device, the game sends anonymous usage data to our analytics provider (Amplitude), the free game may show ads served by Google AdMob, and optional purchases are handled by Apple or Google. The game asks for no camera, microphone, contacts, photo library, or location permission.

2. No Account Required

Numberwise is playable without signing in. There is no registration and no player profile on our servers. We do not ask for your name, email address, phone number, date of birth, or postal address.

3. Data Saved on Your Device

Your level progress, stars, coin balance, the board you are playing, and your sound and haptics settings are stored only on your device. They are not sent to us. Deleting the app deletes them.

4. Advertising (Google AdMob)

The free game may show a banner while you play, full-screen ads between levels or when you return to the game, and optional reward videos you can choose to watch for an extra hint or extra numbers. These are served by Google AdMob. Buying Remove Ads turns all of them off. To show and measure ads and to prevent fraud, Google may collect:

• device identifiers such as the Android advertising ID, and on iOS Apple's advertising identifier (IDFA) only if you allow tracking when the game asks;
• device and app information, such as model, operating system version, language, and app version;
• approximate location derived from your IP address;
• ad interactions (views and taps) and diagnostic data.

In the European Economic Area, the United Kingdom, and Switzerland you are shown Google's consent form before personalised ads are used. You can change or withdraw consent at any time with Privacy choices in the game's Settings. On iOS you can change tracking permission in the iPhone Settings app. Learn more in Google's advertising policy.

5. In-App Purchases

You can buy Remove Ads or coin packs. Payments are processed by Apple (App Store) or Google (Google Play); we never see your card or payment details. To confirm and restore purchases we use RevenueCat, which receives your purchase receipts, the products you bought, and a random app user ID. See RevenueCat's privacy policy.

6. Usage Data (Amplitude)

The game sends anonymous gameplay events to Amplitude, our analytics provider, such as app opened, level started, level completed, hint or extra numbers used, shop opened, purchase started or completed, and ad shown, together with a random device ID created by the analytics library, device model, operating system, app version, and approximate location (country or region) derived from your IP address. We also use Amplitude to switch game features on or off remotely.

We use this only to improve the puzzles and the game. It is not linked to your identity and we do not use it to target ads. See Amplitude's privacy policy.

7. How We Share Data

We do not sell your data. Data is shared only with the providers described above (Google AdMob, Apple or Google for payments, RevenueCat, and Amplitude) for the purposes described in this policy.

8. Children

The game is not directed at children under 13, and we do not knowingly collect personal data from them. If you believe a child has provided us with personal data, please contact us and we will delete it.

9. Data Retention and Your Rights

We keep usage data only as long as we need it to improve the game. You can ask us to delete usage data linked to your device, or ask any question about this policy, at contact@intohash.online. Depending on where you live (for example under the GDPR or the CCPA), you may have rights to access, correct, or delete your data and to object to processing.

10. Changes to This Policy

If this policy changes, we will update this page and the date below.
