02 · Data we collect

Data you provide directly

No account, registration, real-name profile or login is required to play. If you contact support, we receive the email address and the information you choose to include in your message.

Advertising data

Both games use Google Mobile Ads (AdMob). When an ad is requested or shown, Google’s SDK may process categories such as:

  • the Android advertising ID or another resettable advertising/device identifier;
  • IP address and coarse location inferred from it;
  • device model, operating system, language, country, network and app version;
  • ad requests, impressions, clicks, rewards or other ad interactions; and
  • diagnostic and performance information used to detect errors and fraud.

Google explains its app data practices in its How Google uses data from apps page and Privacy Policy.

Last Tower: Monster Siege analytics and crash data

Last Tower: Monster Siege uses Google Firebase Analytics and Firebase Crashlytics. They may process an app-instance identifier generated by Firebase, device model, operating system, language, country, app version, coarse gameplay events (for example level start and end, wave reached, game mode, ads watched and purchases made) and, when the app crashes or logs an error, crash reports with stack traces and recent log messages. This data does not include your name, email address or contacts, and is used in aggregated form to understand how the game is played and to fix problems. Google explains Firebase data practices at firebase.google.com/support/privacy.

Purchases

In-app purchases are processed by Google Play. We do not receive or store your payment card or billing details. The game receives a purchase confirmation (product identifier, order/transaction identifier and purchase status) from Google Play in order to deliver the purchased item and restore non-consumable purchases such as Remove Ads.

Local game data

Game progress, scores, preferences and audio/settings data may be stored in the app’s local storage. We do not receive this local data as a player database. Uninstalling the game normally removes local data from the device.

Find Number 1 to 100 multiplayer data

When you choose multiplayer, the game connects to Photon Cloud for matchmaking and real-time gameplay. The game may send or receive a generated nickname, room and actor identifiers, app/game version, selected region, level/seed information and gameplay events needed to run the two-player match. Photon may also process the connecting device’s IP address and the user ID supplied by the game for networking. We do not use multiplayer for account registration, identity verification, advertising profiles or chat.

Data we do not request

The games do not request contacts, photos, files, camera, microphone, call logs, SMS, health data or precise GPS location.

03 · How we use data

  • to display, measure and fund advertising;
  • to prevent advertising fraud and abuse;
  • to connect Find Number 1 to 100 players to a two-player room and deliver gameplay events;
  • to diagnose technical problems and improve reliability;
  • to understand, in aggregate, how Last Tower: Monster Siege is played so we can balance difficulty and improve the game;
  • to deliver and restore in-app purchases;
  • to respond to support messages; and
  • to comply with legal obligations and protect the services.

Where consent is required for personalised advertising, consent is requested through the applicable Google consent tools. You can refuse or change your advertising choice as described below.

04 · Service providers

We use the following third-party services to operate the games:

Google Mobile Ads / AdMob

Provides banner, interstitial and other advertising services. Google’s policies are available at policies.google.com/privacy and How Google uses data from apps.

Google Firebase (Analytics, Crashlytics)

Provides gameplay analytics and crash reporting for Last Tower: Monster Siege. See Privacy and Security in Firebase.

Google Play Billing

Processes in-app purchases for Last Tower: Monster Siege under the Google Payments Privacy Notice.

Photon Cloud / Exit Games

05 · Your choices

You can continue playing without personalised advertising. Ads may still appear, but they can be selected using contextual information.

  • On Android, use Settings → Google → All services → Ads to manage or reset the advertising ID and advertising preferences.
  • When Google’s consent message is shown, choose whether to consent to personalised advertising. You can also use the choices provided by Google where available.
  • You can stop multiplayer network processing by not selecting the multiplayer mode. Single-player play remains available.

06 · Sharing and retention

We do not sell your information directly for money. Data is shared with the service providers described above only as needed for advertising, multiplayer networking, analytics, diagnostics, purchases, security and support. We may also disclose information when legally required or necessary to protect rights, safety or property.

We do not maintain our own player account database. Local game data remains on the device. Google (including Firebase and Google Play) and Photon retain data according to their own policies and operational requirements. Support emails are kept only as long as reasonably needed to answer the request and maintain support records.

These providers may process data in countries outside your own. They apply their own security, transfer and retention terms as described in their policies.

07 · Children

The games are not directed to children under 13. We do not knowingly collect personal information from children through accounts because the games do not offer accounts or login. If you believe a child has sent us personal information, contact us so we can review and delete it where appropriate.

08 · Your rights

Depending on your location, you may have rights to access, delete, correct, restrict or object to processing, withdraw consent and opt out of personalised advertising. Because the games do not create player accounts, we may not be able to identify a request without additional information. You may also use the controls provided by Google and Photon in their respective policies.

09 · Changes and contact

We may update this policy when the games, services or legal requirements change. The date at the top shows the current version. If a change materially affects data use, we will provide additional notice where appropriate.
