Privacy Policy

Effective 3 November 2026Developer: Sintios (KAVIO LABS SOFTWARE LIMITED)[email protected]

The short version

  • Your campaign progress, stars, credits, steel, tanks, upgrades and settings are stored only on your phone. We have no server and no account for this game.
  • The game shows ads from Unity Ads: videos you choose to watch for a reward, and an occasional full-screen ad between missions. Unity collects device and usage data to show and measure those ads. Anyone who buys anything never sees the between-mission ads.
  • You decide about personalised ads: in Settings, and through a one-time question in the UK, EU and Switzerland. On iPhone, tracking needs your permission.
  • Purchases (Plus, the starter pack, premium tanks and credit packs) are handled by Apple or Google Play. We never see your payment details.

This policy explains how Tank Commander: Iron Front ("the app"), our tank action game for iPhone, iPad and Android, handles information. The app is made by Sintios ("we", "us"), the trading name of KAVIO LABS SOFTWARE LIMITED.

1. What stays on your phone

Your mission stars and best times, credits, steel and fuel, the tanks you own with their upgrades, daily operations, login streak, medals and your settings (sound, vibration, graphics, language, controls, personalised ads) are kept in the app's private storage on your phone. A small ad file keeps how many missions you played and when the last ad was shown, so the app can space ads out. Missions and daily operations are generated on the phone, and the game itself works offline.

Test builds can keep a small performance log (frame rate, device model, graphics settings) in the same private storage so that testers can copy it and send it to us themselves. It is never sent automatically.

Your phone's own backup (iCloud or Google backup, if it's on) may include this data, as with any app. That backup belongs to your Apple or Google account; we can't access it.

2. Ads (Unity Ads)

The game is free to play and is partly paid for by ads served by Unity Ads (Unity Technologies and its affiliates). We use two kinds:

  • Rewarded ads, only when you tap for them: a second chance when your tank's armour runs out (once per mission), double credits and steel on the result screen, and a free daily bonus.
  • Occasional full-screen ads between missions: only when you leave a result screen, never during a mission, never in your first session or first three missions, at most one every three missions and at least two minutes apart. If you have bought anything (Plus, a pack, a tank or credits), you never see these.

The app has no banner ads. To show, cap and measure ads and to prevent fraud, the Unity Ads software in the app collects data from your device and sends it to Unity: device identifiers (the advertising ID (IDFA on iPhone, only if you allow tracking; Google advertising ID on Android) and an identifier for this app on this device), your approximate location derived from your IP address, device and network information (model, operating system, language, screen, connection), and how you interact with ads. Diagnostics such as crash and performance data about the ad software may also be sent. Unity uses this data for advertising and analytics and, on iPhone, for tracking only if you allow it. Unity acts as an independent controller for this data; see Unity's privacy policy, which also explains how to opt out and how to ask Unity for access to or deletion of that data. We don't link this data to your identity, and we don't receive it about you from Unity, only totals such as how many ads were shown.

3. Personalised ads and tracking: your choice

  • UK, EU, EEA and Switzerland: after your first mission the app asks once whether Unity may use your data for personalised ads. Both answers are equally easy and the game works the same either way. Until you answer, ads are not personalised.
  • Everywhere: you can switch personalised ads on or off at any time in Settings → Personalised ads. Off means Unity shows ads without using your data for personalisation.
  • iPhone: the app asks for permission to track (Apple's App Tracking Transparency) once, after your first mission, and only if you allowed personalised ads. It never asks at launch. You can change this in iOS Settings → Privacy & Security → Tracking. Without permission the advertising ID is not shared.
  • Android: you can reset or delete your advertising ID in your phone's Settings → Privacy → Ads (the exact place depends on the phone).

4. Purchases and the Plus subscription

Tank Commander Plus (monthly or yearly, with a free trial for new subscribers), the starter pack, the premium tanks and the credit packs are sold through the App Store or Google Play. Apple or Google processes the payment and tells the app on your phone what you bought, so your purchases can be restored. We don't receive your name, account, card or payment details. Apple's and Google's own privacy policies cover the purchase itself. Every purchase names exactly what you get: there are no random loot boxes.

Buying on sintios.com and your Sintios account

You can also buy Tank Commander's paid features on our website (Tank Commander on the web). The seller is KAVIO LABS SOFTWARE LIMITED and Stripe (Stripe Payments UK Ltd and its affiliates) processes the payment, by card, Apple Pay or Google Pay: your card or wallet details, billing details and email go to Stripe, never to us. Stripe acts as an independent controller for its own legal and fraud-prevention duties (Stripe's privacy policy).

For web purchases, and only if you choose to sign in (Settings → Sintios account), we keep a small Sintios account: your email address; what you bought, its status and dates, Stripe's reference numbers and when you ticked the box to start access straight away; and sign-in links, codes and sessions, stored only as hashes. You sign in with a one-time code we email you (single use, valid 15 minutes); there is no password. The app asks our server which purchases are linked to your email so it can unlock them; nothing else about how you use Tank Commander is sent. We don't use the account for marketing.

Deleting it: in the app (Settings → Sintios account → Delete account) or at sintios.com/account. Any web subscription is cancelled and your email, purchase list and sign-ins are deleted from our server straight away. Payment and invoice records are kept by Stripe, and by us in our accounts, for as long as tax and accounting law requires (in the UK, generally six years); they are used for nothing else. App Store labels: if you sign in, "Contact Info: Email Address", linked to you, used for app functionality only.

5. App Store and Google Play labels

Because the Unity Ads software collects data, the app's App Store privacy label lists, as not linked to you: identifiers (Device ID), coarse location and usage data (product interaction and advertising data), used for third-party advertising and analytics and marked as used for tracking (on iPhone the advertising ID is only shared if you allow tracking); and diagnostics (crash and performance data), used for analytics and app functionality and not used for tracking. Its Google Play data safety section lists approximate location, the advertising ID, app interactions, crash logs and diagnostics as collected and shared with Unity for advertising, analytics and fraud prevention, encrypted in transit. None of it is collected by us. The only data linked to you is the email address of the optional Sintios account, described above.

6. What we don't do

  • No game account (other than the optional Sintios account for web purchases), chat or online multiplayer, and no analytics or tracking code of our own. (Duels are planned for a later version; if they arrive, this policy will be updated first.)
  • No location permission, contacts, photos, camera or microphone access.
  • We don't sell personal data, and we don't receive any personal data about you from the game or its ads.

7. Delete your data

Everything the app stores lives on your phone; deleting the app deletes it. Your subscription and purchases stay with your Apple or Google account; use Restore purchases in the Shop or Settings to get Plus and your premium tanks back after reinstalling. Credits and steel are part of your progress on the phone and are deleted with it. To stop Plus, cancel it in your App Store or Google Play subscription settings. For data held by Unity, use the request options in Unity's privacy policy; resetting your advertising ID also breaks the link to past ad data.

8. Your rights

You can change sound, vibration, graphics quality, language, the control layout and personalised ads in Settings at any time. Data protection laws such as the UK and EU GDPR give you rights over personal data held about you, including access, deletion and objection, and the right to withdraw consent at any time (Settings → Personalised ads). We hold no personal data from the game itself; for ad data, contact Unity as described above. You can always contact us with questions, and you may complain to your data protection authority (in the UK, the ICO).

9. Children

Tank Commander is an action game with vehicles and explosions but no blood. It is meant for players aged 13 and over and is not directed at children under 13, so its ads are not aimed at children. It has no chat and no game accounts. Purchases go through Apple or Google, where parents can use Ask to Buy, Screen Time or Google Play parental controls.

10. Changes and contact

If we change how the app handles data, for example if a future version adds online duels or leaderboards, we'll update this policy and its date first and, for significant changes, tell you in the app or release notes. Questions: [email protected].
