Terms of Service

Effective date: November 15, 2026 · Last updated: November 15, 2026

These Terms of Service ("Terms") govern your use of the mobile applications published on Google Play by Neumann Studio ("we", "us", or "our"), including any subscriptions, in-app purchases, content, and related services (each an "App" and together the "Apps"). By downloading, installing, or using an App, you agree to these Terms. If you do not agree, do not use the Apps.

1. Eligibility

You must be at least 13 years old (or the minimum age of digital consent in your country) to use the Apps. If you are under the age of majority where you live, you may use the Apps only with the involvement and consent of a parent or legal guardian, who agrees to these Terms on your behalf. Purchases by minors must be made with parental permission.

2. License to Use the Apps

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable license to download and use the Apps on Android devices that you own or control, solely for your personal, non-commercial use. This license is also subject to the Google Play Terms of Service.

All rights not expressly granted to you are reserved by us. The Apps are licensed, not sold.

3. Acceptable Use

You agree not to:

4. Advertising

Free versions of the Apps display advertisements provided by third-party networks such as Google AdMob. We do not control the content of third-party ads and are not responsible for the products or services they promote. Your interactions with advertisers are solely between you and the advertiser. Information collected for advertising is described in our Privacy Policy.

5. Subscriptions and In-App Purchases

5.1 Purchases through Google Play. Some Apps offer paid subscriptions ("Premium") or one-time in-app purchases that unlock additional features or remove ads. All payments are processed by Google Play and are subject to the Google Play Terms of Service and payment policies. Prices are shown in the App and on Google Play before you purchase, and may vary by region and include applicable taxes.

5.2 Automatic renewal. Subscriptions automatically renew at the end of each billing period (for example weekly, monthly, or yearly) at the then-current price, and your Google Play payment method will be charged, unless you cancel before the renewal date. We will notify you in advance of any price increase as required by Google Play and applicable law.

5.3 Free trials and introductory offers. Some subscriptions may include a free trial or discounted introductory price. Unless you cancel before the trial or introductory period ends, you will automatically be charged the regular subscription price. Eligibility for trials may be limited (for example, one per user or Google account).

5.4 How to cancel. You can cancel a subscription at any time in the Google Play Store app: open Google Play › Profile icon › Payments & subscriptions › Subscriptions, select the subscription, and tap Cancel subscription. Uninstalling an App does not cancel your subscription. After cancellation, you will keep access to Premium features until the end of the current paid period.

5.5 Refunds. Refunds are handled by Google Play according to its refund policies. You can request a refund through Google Play within the period it allows. Except where required by applicable law, we do not provide refunds or credits for partial subscription periods or unused features. Nothing in these Terms limits any rights you have under consumer protection laws in your country.

5.6 Restoring purchases. Purchases are linked to the Google account used to make them. You can restore them on a new device signed in to the same Google account, using the "Restore purchases" option where available.

5.7 Changes to features and pricing. We may change the features included in free or paid tiers, or change subscription prices, from time to time. Price changes for existing subscriptions will follow Google Play's notification and consent requirements.

6. Intellectual Property

The Apps and all related content, including software, designs, graphics, text, logos, and trademarks, are owned by us or our licensors and are protected by intellectual property laws. Content you create with an App remains yours; you are responsible for having the rights to any content you import or use in an App.

7. Third-Party Services

The Apps may include or link to third-party services, content, or websites (such as Google Play, advertising networks, and analytics providers). Your use of them is subject to their own terms and privacy policies, and we are not responsible for them.

8. Updates and Availability

We may update, modify, suspend, or discontinue any App or feature at any time, with or without notice. Some updates may be required to continue using an App. If we discontinue an App that includes an active subscription, we will handle it in accordance with Google Play policies and applicable law. We do not guarantee that the Apps will be available at all times or on all devices.

9. Disclaimer of Warranties

To the fullest extent permitted by law, the Apps are provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, or uninterrupted or error-free operation. You use the Apps at your own risk, and you are responsible for backing up your data.

10. Limitation of Liability

To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or revenue, arising out of or related to your use of or inability to use the Apps. Our total liability for any claim relating to the Apps will not exceed the greater of (a) the amount you paid us for the relevant App in the twelve (12) months before the claim, or (b) USD 50.

Some jurisdictions do not allow certain exclusions or limitations of liability, so some of the above may not apply to you. Nothing in these Terms excludes liability that cannot be excluded under applicable law.

11. Indemnification

You agree to indemnify and hold us harmless from any claims, losses, liabilities, and expenses (including reasonable legal fees) arising from your misuse of the Apps or your violation of these Terms or of any law or third-party right.

12. Termination

We may suspend or terminate your access to the Apps at any time if you violate these Terms. You may stop using the Apps at any time by uninstalling them (and cancelling any subscription through Google Play). Sections that by their nature should survive termination will survive, including Sections 6, 9, 10, 11, and 13.

13. Governing Law and Disputes

These Terms are governed by the laws of Vietnam, without regard to its conflict-of-law rules. Any dispute will be resolved by the competent courts of Vietnam, unless mandatory consumer protection laws of your country of residence give you the right to bring a claim in your local courts. Before filing a claim, please contact us so we can try to resolve the issue informally.

14. Changes to These Terms

We may update these Terms from time to time. We will update the "Last updated" date above and, for material changes, may notify you within the App. Continued use of the Apps after changes take effect means you accept the updated Terms.

15. Miscellaneous

If any provision of these Terms is found unenforceable, the remaining provisions will remain in effect. Our failure to enforce any right is not a waiver of that right. These Terms, together with our Privacy Policy, are the entire agreement between you and us regarding the Apps. Individual Apps may have additional terms, which will be presented within that App.
