Terminal Angle — Privacy Policy

Last updated: 1 October 2026

This policy explains what data Terminal Angle: Armored Tower Defence ("the game") collects, why, and what you can do about it.

1. Who we are

The data controller is GONEXTSO YAZILIM ÜRÜNLERİ SANAYİ VE TİCARET LİMİTED ŞİRKETİ ("GONEXTSO", "we"), Mecidiyeköy Mah. Selahattin Pınar Aralığı Sk. Hüseyin Özer İş Merkezi No: 3 İç Kapı No: 8, Şişli / İstanbul, Türkiye.
Contact for any privacy request: support@gonextso.com

2. Age

The game is intended for players aged 16 and over. We do not knowingly collect data from children under 16. If you believe a child under 16 has an account, contact us and we will delete it.

3. What we collect and why

We do not ask for your name, e-mail address, phone number or precise location to play the game.

Data	Why	Legal basis
Device credential: a random secret our server creates on first launch, stored on your device: in Google Block Store on Android, and in the Apple Keychain on iPhone and iPad. On iOS it stays on the device. We keep only a one-way hash of it.	To open your account on this device without a password.	Performance of contract
Google account identifier: only if you choose "Link Google account" on Android. We store only Google's numeric account ID (`sub`). We do not store your e-mail, name or photo.	To let you open the same account on another device.	Performance of contract
Session tokens (stored as hashes)	To keep you signed in securely.	Performance of contract
Player tag and chosen title	Shown on your profile and on public leaderboards.	Performance of contract
Country / continent: suggested from your device's time zone; you confirm or change it. We do not use your IP address to locate you.	Country and continent leaderboards and weekly leagues.	Performance of contract
Device time zone and UTC offset: e.g. `Europe/Istanbul`, +180 minutes. The offset is also recorded with your play sessions.	So daily, weekly and monthly limits and rewards reset on your local day; for time-of-day reward bonuses; to suggest your country.	Performance of contract
Game progress: currencies, inventory, research, upgrades, run results, achievements, statistics, saved run	To run the game.	Performance of contract
Purchase records: store (Google Play or App Store), transaction ID, product, amount, currency, country	To deliver and restore purchases and prevent fraud; accounting obligations.	Contract; legal obligation
Push notification token and the game's language setting: only if you allow notifications	To send game notifications in your language. You can turn this off in your device settings.	Consent
IP address	Rate limiting and security. Kept in short-lived counters.	Legitimate interest (security)
Play Integrity verdict (Android only): when the game opens or renews your session, Google Play checks that it is the genuine game installed from Google Play, running on a genuine device, and returns a verdict. Google collects the device and app information it needs for this under its own privacy policy. We receive only the verdict, check it, and do not store it. What we send to Google is a one-way hash of the request, never your device credential. We keep a record that the verdict was used for about six minutes, so it cannot be reused, and then it is deleted automatically.	To prevent cheating, account abuse and fraud.	Legitimate interest (security)
Google Play Games achievements (Android only): if you are signed in to Google Play Games on your device, the game reports your achievement progress to Play Games so it appears in your Play Games profile. Signing in to Play Games and your Play Games profile are handled by Google. Our servers do not receive or store your Play Games player ID.	To show your achievements in Google Play Games.	Performance of contract
Security events: e.g. suspected session-token theft	To protect accounts.	Legitimate interest (security)
Support correspondence: if you e-mail us (e.g. an account deletion request), your e-mail address and what you write	To answer your request; for a deletion request, to confirm the account is yours.	Legal obligation; legitimate interest

We do not use analytics or crash-reporting SDKs, and we do not sell your data.

4. Advertising

The game offers optional rewarded ads that you choose to watch. Ads are served and managed by Google AdMob. Ads are personalised: to show you ads that match your interests, AdMob may use device identifiers (such as the advertising ID), IP address and ad interaction data under Google's own policies. Where required (for example in the EEA, UK and Switzerland), we ask for your consent through Google's consent form (UMP) before showing personalised ads. On iPhone and iPad, the advertising identifier (IDFA) is used only if you allow it in Apple's App Tracking Transparency (ATT) prompt. If you do not allow it, you see non-personalised ads; watching ads and their rewards never depend on that choice.

5. Service providers and international transfers

Google: Google Play Billing (payments), Block Store and Credential Manager / Sign in with Google (sign-in), Google Play Games Services (achievements), the Play Integrity API (app and device integrity checks), Firebase Cloud Messaging (notifications), AdMob and UMP (ads), and Google Workspace (Gmail) for our support mailbox, support@gonextso.com. For your Google account and your Play Games profile, Google is a separate controller under its own privacy policy: https://policies.google.com/privacy
Apple: the App Store and In-App Purchase (payments), and the Apple Push Notification service (APNs): on iPhone and iPad, Firebase Cloud Messaging hands notifications to APNs, which delivers them to your device. For your App Store account and payment data, Apple is a separate controller under its own privacy policy: https://www.apple.com/legal/privacy/
Railway: hosting of our servers and databases. Railway manages the infrastructure and the region where the servers are located, which may change.

Google Play and the App Store take the payments; we never see your card or bank details, only the purchase record in §3. The service providers we share your data with protect it to the same or an equal level as described in this policy.

International transfers. Terminal Angle is one online game in which players from all over the world share the same leaderboards and leagues. So every player's data, wherever they live, is kept in a single shared database. That single database is kept outside Türkiye, on servers managed by Railway (a US-based company); the region where they are located may change. The data in §3, except support correspondence, is transferred there and stored there; support e-mails are kept in Google Workspace. The Google and Apple services above may also process data outside Türkiye, for example in the United States.

Türkiye has not yet issued an adequacy decision for any country, so in the countries where your data is processed it may not be protected to the same level as in Türkiye or the EU.

When you tick "I have read and accept" under the Terms of Service and this policy on your first start, you agree to your data being transferred and stored outside Türkiye in this way (Terms of Service §3).

6. How we collect data

Data is collected electronically and automatically, through the app and our servers, when you use the game. If you e-mail us, what you write is collected electronically, by non-automated means.

7. Retention

Account data is kept while your account exists and deleted when you delete it (§8).
If you move to another account with "Link Google account" (because that Google account already belongs to another Terminal Angle account), your purchases move with you and the account you leave is kept for 90 days, then deleted automatically.
Purchase records are kept after account deletion, with the link to your account removed, for as long as accounting and tax obligations require.
Security event records and the player tags you used before a rename are kept with the link to your account removed.
When you change your tag, the old one is reserved for 48 hours so no one else can take it immediately.
Support correspondence is kept for as long as we need it to show how your request was handled.
Technical details: GONEXTSO YAZILIM ÜRÜNLERİ SANAYİ VE TİCARET LİMİTED ŞİRKETİ reserves the right to determine and change technical details such as backups and server logs.

8. Deleting your account and data

In the game: Settings → System → Erase my progress. This permanently deletes your account and its data from our servers and starts a new game.
Without the game: at https://www.gonextso.com/terminal-angle/delete-account or by e-mailing support@gonextso.com.
Uninstalling the game does not delete your account. The device credential stays in the Keychain on iPhone and iPad and in Google Block Store on Android, so reinstalling the game on the same device usually opens the same account.

9. Your rights

Under Article 11 of the Turkish Personal Data Protection Law (KVKK), you may apply to the data controller to:

learn whether your data is processed and, if so, ask for information about it;
learn the purpose of the processing and whether the data is used for that purpose;
know the third parties in Türkiye or abroad to whom it is transferred;
ask for incomplete or incorrect data to be corrected;
ask for it to be erased or destroyed under KVKK Article 7;
ask for corrections and erasures to be passed on to the third parties who received it;
object to an outcome against you that results solely from automated analysis;
claim compensation if you suffer damage from unlawful processing.

If you live in the European Union, your rights under the GDPR (for example restriction of processing, data portability, objection and withdrawal of consent) also apply.

Send requests in writing by post to the address in §1, or by e-mail to support@gonextso.com. We answer within 30 days. You may also complain to the Turkish Personal Data Protection Board (KVKK Kurulu) and, if you live in the EU, to the data protection authority of your country.

10. Security

Credentials are stored only as hashes. All traffic is encrypted (HTTPS). Access to servers is restricted.

11. Changes

We will post changes here and update the date above. For material changes, we will also tell you in the game.
