Neumann Studio

Privacy Policy

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

This Privacy Policy explains how Neumann Studio ("we", "us", or "our") collects, uses, and shares information when you use any of our mobile applications published on Google Play under our developer account (each an "App" and together the "Apps"). This policy applies to all of our Apps unless a specific App provides its own separate privacy notice.

By installing or using an App, you acknowledge that you have read and understood this Privacy Policy. If you do not agree, please do not use the Apps.

1. Information We Collect

We do not require you to create an account, and we do not ask for your name, address, or phone number in order to use the Apps. However, some information is collected automatically by the Apps and by the third-party services we use.

1.1 Information collected automatically

• Device and app information: device model, operating system version, language, country/region, app version, and screen size.
• Advertising identifiers: the Android Advertising ID (AAID) or app set ID, used for advertising, frequency capping, fraud prevention, and measurement. You can reset or delete your Advertising ID at any time in your device settings.
• Usage and interaction data: features used, screens viewed, session length, ad impressions and clicks, and similar events.
• Diagnostics: crash logs, performance data, and error reports that help us find and fix problems.
• Approximate location: coarse location inferred from your IP address, used by ad networks to serve relevant ads and comply with regional laws. We do not collect precise GPS location unless an App clearly asks for it for a specific feature, and only with your permission.

1.2 Purchase information

When you buy a subscription or in-app product, the payment is processed entirely by Google Play. We do not receive or store your full payment card details. We receive limited information from Google Play, such as a purchase token, order ID, product ID, purchase date, and subscription status, so that we can verify the purchase and unlock premium features.

1.3 Information you provide

If you contact us by email or through in-app feedback, we receive your email address and any information you choose to include in your message.

1.4 Content stored on your device

Content you create in an App (for example settings, files, or notes) is generally stored locally on your device and is not uploaded to our servers unless an App clearly offers a backup or sync feature that you choose to use.

2. How We Use Information

• To provide, operate, and maintain the Apps.
• To display advertising, including personalized ads where permitted and where you have given consent if required by law.
• To process, verify, and restore subscriptions and in-app purchases.
• To understand how the Apps are used and to improve features, performance, and stability.
• To detect, prevent, and address fraud, abuse, security issues, and technical problems.
• To respond to your questions and support requests.
• To comply with legal obligations and enforce our Terms of Service.

3. Advertising

Free versions of our Apps are supported by advertising. We use third-party advertising networks, such as Google AdMob, which may collect and use the information described in Section 1.1 to show ads, measure ad performance, and limit how often you see the same ad.

• Consent (EEA, UK, Switzerland): where required, we use Google's User Messaging Platform (UMP) or another certified consent management platform to ask for your consent before personalized ads are shown. You can change your choice at any time from the privacy/consent option in the App settings (where available).
• US state privacy laws: where applicable, you may opt out of the "sale" or "sharing" of personal information for targeted advertising through the App's privacy settings (where available) or by contacting us.
• Opting out on Android: go to Settings › Google › Ads (or Settings › Privacy › Ads) and choose "Delete advertising ID" or "Reset advertising ID". You will still see ads, but they will be less personalized.
• Ad-free experience: some Apps offer a paid subscription or purchase that removes ads.

4. Third-Party Services

Our Apps may use some or all of the following third-party services. Each has its own privacy policy that governs its use of your information.

5. How We Share Information

We do not sell your personal information for money. We share information only:

• With the third-party service providers listed above, to operate the Apps, show ads, process purchases, and provide analytics.
• When required by law, regulation, legal process, or a valid government request.
• To protect the rights, property, or safety of us, our users, or others.
• In connection with a merger, acquisition, or sale of assets, in which case your information may be transferred as part of that transaction.

Sharing advertising identifiers with ad networks for personalized advertising may be considered a "sale" or "sharing" under some US state laws; see Section 3 for how to opt out.

6. Data Retention

We keep information only for as long as necessary for the purposes described in this policy. Data collected by third-party services is retained according to their own policies (for example, Firebase Analytics data is retained for a configurable period of up to 14 months). Support emails are kept as long as needed to resolve your request and for a reasonable period afterward.

7. Data Security

We use reasonable technical and organizational measures to protect information, and data sent between the Apps and third-party services is encrypted in transit. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

8. Your Rights and Choices

Depending on where you live, you may have the right to:

• Access the personal information we hold about you and receive a copy.
• Correct inaccurate information.
• Request deletion of your information.
• Object to or restrict certain processing, including for personalized advertising.
• Withdraw consent at any time, without affecting processing done before withdrawal.
• Opt out of the sale or sharing of personal information and of targeted advertising.
• Lodge a complaint with your local data protection authority.

Because we generally do not link data to your name or an account, we may need you to provide information (such as your Advertising ID or purchase order ID) to locate data related to you. To exercise these rights, contact us at the email below. We will respond within the time required by applicable law. We will not discriminate against you for exercising your rights.

Data deletion

You can delete locally stored data at any time by clearing the App's data in Android settings or uninstalling the App. To request deletion of any data we or our service providers hold, email us at support@neumannstudio.co with the subject "Data Deletion Request" and the name of the App.

9. Children's Privacy

Our Apps are not directed to children under 13 (or the minimum age required in your country, such as 16 in some EEA countries), and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it. If a specific App is designed for children, it will follow Google Play's Families Policy and will only use certified, family-safe ad networks with non-personalized ads.

10. International Data Transfers

We and our service providers may process information in countries other than where you live, including the United States, whose data protection laws may differ from yours. Where required, these transfers rely on appropriate safeguards such as the European Commission's Standard Contractual Clauses.

11. Legal Bases for Processing (EEA/UK users)

• Performance of a contract: to provide the Apps and process purchases.
• Consent: for personalized advertising and certain analytics where required.
• Legitimate interests: to keep the Apps secure, fix crashes, prevent fraud, and improve our services.
• Legal obligation: to comply with applicable laws.

12. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date above and, for material changes, may also notify you within the App. Continued use of the Apps after changes take effect means you accept the updated policy.
