Provider: Denoli s.r.o. Publisher: 4 Heads Apps
These Terms of Service govern your use of the Authenticator 2FA Codes mobile application and related services. By installing or using the app, you agree to these terms. If you do not agree, do not use the app.

1 Who we are

Authenticator 2FA Codes is developed and operated by Denoli s.r.o. The app may be published and distributed under the publisher name 4 Heads Apps. In these terms, we, us, and our refer to Denoli s.r.o. You and your refer to the user of the app.

2 What the app does

The app helps you generate time based one time passwords and manage two factor authentication accounts. The app may support scanning QR codes, manual entry, importing, exporting, and backup features depending on the version you use.

3 Important security note

Two factor authentication codes help protect access to your accounts, but they are not a guarantee of security. You are responsible for keeping your device, backups, export files, recovery keys, and any app lock credentials safe. If you lose access to your device or backups, you may lose access to your tokens. Denoli s.r.o. and 4 Heads Apps cannot recover tokens for you if you do not have a backup.

4 Eligibility

You must follow all applicable laws and the rules of the app store where you downloaded the app. If local law requires you to be a certain age to use digital services, you must meet that requirement.

5 License and acceptable use

We grant you a personal, limited, non exclusive, non transferable license to use the app for your own lawful purposes. You agree not to do any of the following.

  1. Copy, modify, translate, or create derivative works of the app except where permitted by law
  2. Reverse engineer, decompile, or attempt to extract source code except where permitted by law
  3. Interfere with the app, abuse it, or use it to violate any law or third party rights
  4. Use the app in a way that could damage, disable, or impair the app or related systems

6 Purchases subscriptions trials

Some features may require a purchase or subscription. Pricing and available plans are shown inside the app and may vary by region and platform. Payments are processed by Apple, Google, or another platform provider, not by us.

Subscriptions renew automatically unless cancelled at least twenty four hours before the end of the current period. You can manage or cancel subscriptions in your platform account settings. If a free trial is offered, any unused portion may be forfeited when you purchase a subscription, if applicable.

Refund requests are handled by the platform provider under its refund rules.

7 Data storage and backups

Tokens are primarily stored on your device. Depending on your settings and the platform, your tokens may be included in device backups. Export files and backup features, if enabled, may store encrypted or unencrypted data depending on how you configure them. You are responsible for choosing a safe backup method.

If you enable backup or export, you understand that anyone with access to that backup or export may be able to obtain your tokens.

The app may integrate with third party services such as analytics, crash reporting, cloud storage, or payment systems. Those third parties may have their own terms and policies. We are not responsible for third party services that you choose to use.

10 Intellectual property

The app and all related content are owned by Denoli s.r.o. or its licensors and are protected by intellectual property laws. The publisher name 4 Heads Apps is used for distribution and storefront listing purposes. These terms do not grant you any ownership rights in the app.

12 Termination

You may stop using the app at any time. We may suspend or terminate your use of the app if you violate these terms or if required for legal or security reasons. Sections that by their nature should survive termination will survive, including sections about intellectual property, disclaimers, limitation of liability, and dispute terms.

13 Disclaimers

The app is provided as is and as available. To the maximum extent permitted by law, we disclaim all warranties, express or implied, including fitness for a particular purpose, merchantability, and non infringement. We do not warrant that the app will be uninterrupted, error free, or that it will prevent unauthorized access to your accounts.

14 Limitation of liability

To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, goodwill, or business interruption. To the maximum extent permitted by law, our total liability for any claim relating to the app will not exceed the amount you paid for the app in the twelve months before the event giving rise to the claim, or fifty US dollars if you paid nothing, whichever is greater. Some jurisdictions do not allow certain limitations, so some of these limits may not apply to you.

15 Indemnity

You agree to indemnify and hold harmless Denoli s.r.o. and 4 Heads Apps from any claims, losses, liabilities, and expenses, including reasonable legal fees, arising out of your misuse of the app or your violation of these terms.
