Privacy Policy

Tankr Privacy Policy and Service Terms
SERDIA IT SRL ("we", "us", or "our") built the Tankr application as a commercial app. This Service is provided by SERDIA IT SRL and is intended for use as is.
This Privacy Policy explains how we collect, use, process, and disclose information when you use Tankr. Sections 3 and 9 also describe our Service Terms concerning subscriptions, AI report allowances, and access restrictions.
1. Information Collection and Use
To provide and improve the Service, we collect and process specific types of information. The information we request is retained by us or processed on our behalf by third-party service providers and used as described in this Privacy Policy.
Game Data
Your public World of Tanks account identifier, in-game username, region, and public in-game statistics, including battles, win rate, damage, tank-specific performance, WN8, WTR, and related performance metrics.
Search Data
Player names or search queries entered in the app, recently viewed players, and related region selections used to provide search and quick access features.
App Activity
Analytics events regarding how you interact with the app’s features.
Device and Network Information
Device identifiers, installation IDs, operating system version, and IP addresses required to operate the app, sync subscription states, verify app integrity, and route network requests.
AI Ranker Session and Usage Data
Anonymous Firebase Authentication identifiers, subscription owner identifiers, report request identifiers and status, timestamps, daily report usage, preview usage, and player battle progress records. These are used to verify access, manage allowances, prevent duplicate generation, and recover interrupted requests. Anonymous session identifiers can distinguish installations or sessions and are not fully anonymized data.
Saved Reports and Recovery Data
Generated reports, related gameplay evidence, and previous report context may be stored locally. Completed report results are also temporarily stored on our backend for recovery.
Diagnostic Data
Crash logs and performance diagnostics used to identify and fix bugs.
Legal Bases for Processing
Where applicable data protection law requires a legal basis, we process information necessary to provide requested features and administer subscriptions to perform our contract with you. We rely on legitimate interests, where legally permitted, for security, fraud prevention, reliability, support, and limited service analytics, balanced against your rights. We also process information where required by law. Where consent is legally required, it must be obtained; where processing relies on consent, you may withdraw it without affecting the lawfulness of earlier processing.
2. Third-Party Service Providers
We use third-party service providers to facilitate the Service, process data on our behalf, and analyze app usage. These services may collect device identifiers, usage data, diagnostics, purchase verification data, or network information as needed to provide their services.
Google Play Services & Google Play Billing
Used for Android app services and Android subscription processing.
Apple App Store / StoreKit
Used for iOS subscription processing, purchase transactions, subscription management, and refund/cancellation handling through Apple.
RevenueCat
Used to manage and verify in-app subscription state and entitlements. RevenueCat and app store services process customer identifiers, subscription identifiers, product IDs, entitlement status, and purchase verification data.
Firebase Authentication
Used to establish anonymous app sessions for supported AI Ranker features without requiring an email address or password.
Firebase Cloud Functions & Cloud Firestore
Used for backend processing and storage of subscription ownership, verification, report allowances, request status, battle progress, and temporary report recovery records.
Firebase Analytics & Firebase Crashlytics
Used for app usage analytics and crash reporting.
Firebase App Check / Device Integrity APIs
Used to verify that network requests originate from genuine installations of the app across supported mobile operating systems.
Firebase AI / Vertex AI / Gemini by Google
Used to generate AI Rank analysis when you request a report. Public in-game statistics, such as battles, win rate, damage, tank performance, related gameplay metrics, and previous report context, may be processed by this service to produce the analysis. No payment information or private account credentials are sent to the AI service.
Wargaming.net API
Used to retrieve public World of Tanks player statistics.
XVM / modxvm.com
Used to retrieve WN8 expected values for local statistical calculations.
International Processing
Our providers may process information outside your country, including outside the European Economic Area and in the United States. Where required, transfers must be covered by applicable safeguards, such as an adequacy decision or Standard Contractual Clauses under the relevant provider agreements. You may contact us for information about safeguards applicable to your data.
3. Subscriptions, Payments, and Verification — Service Terms
Tankr offers optional premium features through auto-renewing subscriptions. Direct payment transactions, including credit card processing, are securely handled by the official app store platforms. We do not process, collect, or store your credit card information.
To verify Pro access, Tankr uses app store services and RevenueCat to process purchase verification data, product identifiers, entitlement status, and subscription status. This allows us to provide premium access without handling your financial data directly.
The updated AI Ranker allowance for Trial and Pro is 10 completed AI reports per UTC day, resetting at 00:00 UTC. The allowance is shared across players and devices using the same verified subscription. Reinstalling the app does not reset this allowance.
Viewing saved reports does not consume the allowance. Unfinished failed requests release their reserved report. Recovering an already completed report does not consume another report.
4. Intellectual Property and Wargaming.net API
Tankr is an unofficial third-party application. It is not created, sponsored, endorsed, approved by, or officially connected to Wargaming.net.
World of Tanks names, logos, images, statistics, and in-game content are owned by Wargaming.net or its licensors. Tankr uses public Wargaming.net developer APIs to provide core data. We claim no ownership over raw game data. Use of the Wargaming API is subject to the Wargaming Developer Partner Program Terms of Service.
5. Security and Data Encryption
We value your trust and use commercially acceptable means of protecting your information. Data transmitted between the Tankr app, our backend services, and third-party APIs is encrypted in transit using industry-standard protocols such as HTTPS/TLS.
However, no method of transmission over the internet or method of electronic storage is 100% secure, and we cannot guarantee absolute security.
6. Data Retention, Deletion, and Your Rights
We retain data only for as long as necessary to provide the Service, maintain subscription status, support app functionality, and fulfill the purposes described in this Privacy Policy.
Local saved reports, cached data, and preferences remain subject to the app’s storage controls, device storage settings, and any device backups.
In the current AI Ranker backend, completed report results have a recovery availability period of up to 48 hours. Completed or failed request records have a 30-day expiry for request consistency and duplicate prevention. Expiry and physical storage cleanup are separate processes, so deletion may occur after expiry.
Subscription ownership, allowance, preview, and battle progress records are retained as necessary to administer access, preserve request consistency, and prevent misuse. Uninstalling the app does not itself delete backend records.
Analytics and diagnostic information is retained according to its operational purpose, applicable provider retention settings, and legal requirements.
You may request deletion of your account identifiers and associated backend data by contacting us at the email address below. We may need reasonable information to locate the relevant records and verify your request. Applicable information will be deleted unless retention is necessary for legal obligations, security, billing, fraud prevention, or legal claims.
Depending on applicable law and the circumstances, you may also request access, correction, restriction of processing, or portability of eligible personal data, and object to processing based on legitimate interests. Where processing relies on consent, you may withdraw that consent.
We respond to privacy requests without undue delay and normally within one month, subject to extensions permitted by applicable law. You may lodge a complaint with a competent data protection authority, including Romania’s ANSPDCP where appropriate.
Deleting Tankr data does not cancel an app store subscription or remove public game data held by Wargaming or records independently controlled by app stores.
7. Children’s Privacy
The Service is not directed to children under the age of 13, or the applicable age of consent in your region. We do not knowingly collect personally identifiable information from children.
If we discover that a child has provided personal information, we will delete it. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.
8. Changes to This Privacy Policy and Service Terms
We may update this Privacy Policy and these Service Terms from time to time. Any changes will be posted on this page with an updated effective date. Where required by law, we will provide notice of material changes and obtain any required consent.
9. Suspension, Termination & Refund Abuse — Service Terms
We reserve the right, to the fullest extent permitted by applicable law, to suspend, restrict, or terminate access to Tankr, including both free and premium features, and to refuse future subscriptions, purchases, or account access where we reasonably determine that a user has:
• Abused or attempted to abuse our free trial, subscription, cancellation, or refund policies through fraudulent or deceptive conduct;
• Engaged in fraudulent, deceptive, abusive, malicious, or unlawful behavior;
• Violated these Service Terms or any applicable laws;
• Attempted to exploit, interfere with, circumvent, or misuse the Service or its security mechanisms;
• Reverse engineered the Service except where permitted by applicable law;
• Infringed or attempted to infringe our intellectual property rights or legitimate business interests.
Following a refund, revocation, or chargeback, Tankr may revoke the corresponding premium entitlement. Broader access restrictions require a reasonable basis, such as evidence of fraud, deliberate abuse, or a material violation of these Service Terms, and must be proportionate to the circumstances.
A legitimate cancellation or refund request, including one made after using premium features, is not by itself proof of abuse.
We reserve the right to implement reasonable technical and administrative measures to enforce justified restrictions, including the use of account-based, subscription-based, purchase-based, device-based, payment-related, or other technical identifiers, where permitted by applicable law.
You may contact us to request review of an access restriction.
Nothing in this section limits any statutory consumer rights that cannot legally be excluded under applicable law.
