Nation Wars: Tower Conquest — Privacy Policy

Effective October 5, 2026 (replaces the version of October 1, 2026) · app space.oleks.siegelines · publisher KOT Kanagrilli (Finland) · contact kotkanagrilli@gmail.com

Summary

Nation Wars is a country-vs-country strategy game. The campaign is played offline. The online part (Arena, challenges, chat, voice, friends, cloud save) talks to our own game server. There is no sign-in with an e-mail or a password: your player identity is a random id created on first launch. You choose a nickname and a country in the game — that is what other players see.

We collect only what the game needs to work, to show ads, to verify purchases and to fix bugs. We do not sell your data. We do not collect your e-mail, phone number, contacts or precise location.

What we collect and why

Location: we do not ask for GPS. Your country in the game is the one you pick. Google AdMob may derive an approximate location from your IP address to serve ads (see below).

Advertising

The game shows ads through Google AdMob (rewarded ads you choose to watch and an interstitial after some battles). Before you play, the game asks you to accept this policy and the Terms of Use and lets you choose whether ads may be personalised (off by default: ads are then requested as non-personalised). AdMob and its partners may use the Android advertising ID, IP address (approximate location) and device information to serve and measure ads. In addition, players in the EEA, the UK and Switzerland see Google's consent dialog (User Messaging Platform). You can reset the advertising ID in Android settings. Google's policy: https://policies.google.com/technologies/ads.

Purchases, rubies and random items

Purchases go through Google Play Billing: we never see your card or bank details. Some items bought with rubies are random (equipment chests and hero summons). The exact odds of every rarity are shown in the game under the button, in the confirmation dialog and behind «ⓘ» before you pay.

Third parties

Google Play services (Billing, Play Games, Firebase Cloud Messaging) and Google AdMob. We use no other analytics, tracking or advertising SDK. The game server, purchase ledger and statistics are run by us in the European Union (Finland). Chat messages are filtered automatically on our server; reports from players can mute an account for a while.

Children

The game is intended for players aged 13 and over. We do not knowingly collect data from children under 13. If you believe a child has created a profile, write to us and we will delete it.

Your rights and data deletion

• Uninstalling the app deletes everything stored on your device (progress, settings, saves).
• To delete your account, use Menu → Profile → «Account and other nicks» → «Delete account» in the game, or follow Delete your account — it lists what is deleted and what is kept.
• To delete your server-side data (profile, cloud save, friends, purchase ledger entries that are no longer needed for fraud prevention) or to get a copy of it, e-mail kotkanagrilli@gmail.com from the game (Menu → «Write to us») or directly, with your nickname and country. We answer within 30 days. Your public chat lines of the last 30 days are included in the copy and deleted on request.
• EU/EEA residents have the rights of the GDPR (access, rectification, erasure, restriction, portability, objection) and may complain to their supervisory authority.

Changes

We update this policy when the game changes and update the effective date above. This page is the canonical version. Previous versions: October 1, 2026 (said that chat was not written to disk — the public-room log existed, now it is limited to 30 days) and September 7, 2026 (offline-only build without a server, ads or purchases).
