Privacy Policy
Logic Studio PLC is a logic and process simulation tool. Your diagrams stay on your device unless you choose to export them. Google Play provides optional PRO purchases and processes billing-related technical data. You do not need to create an account with the developer.
1. Developer and contact
Logic Studio PLC is provided by Andrea Parlato. For privacy questions or requests concerning information held by the developer, contact logicstudioplc@gmail.com.
2. Projects and local storage
Logic diagrams, simulation settings, saved projects and automatic session recovery are processed and stored locally on your device. The app does not upload these contents to a developer-operated server. It also stores the local PRO entitlement status to support offline use.
If you export or import a project, save a PDF or print, Android and the document or print provider you select handle the file. Selecting a cloud storage provider may transfer that file to that provider under its own privacy terms.
3. Google Play purchases
The optional PRO upgrade uses Google Play Billing. The app receives purchase information such as the product identifier, purchase token, purchase state and acknowledgement state to unlock PRO, verify entitlement and restore purchases. The app communicates with Google Play to perform these operations; there is no developer-operated purchase verification backend.
Google handles checkout, payment methods and transaction records. The app does not receive payment card or bank account details, or use your Google account as an in-app login. Google Play may check existing purchases when the app connects to its billing service, including after reinstalling the app. Buying PRO is optional; entitlement verification is part of using purchased features.
4. Billing diagnostics and technical identifiers
The integrated Google Play Billing library sends technical diagnostic events to Google. These include billing operation results and errors, timing information, app and library version information, Android-related technical information and generated identifiers used to correlate billing sessions and events. These data support diagnosis and reliability of the billing service.
The app does not offer a switch to disable the billing library's diagnostic collection. The app contains no advertising SDK and no separate developer-operated usage analytics service. Local billing messages shown in the app are distinct from the diagnostics processed by the Google library.
5. Support communications
If you email the developer, your email address, message and any attachments you choose to send are processed to respond to your request. Do not send payment card details or sensitive plant, customer or company information. Support correspondence is handled through the email provider.
6. Recipients and purposes
Google receives purchase-related and billing diagnostic data through Google Play and its billing library. A document, cloud or print provider receives files only when you choose to use that provider. The developer receives information that you send directly for support. The developer does not sell user data or use it for targeted advertising.
The developer processes information as necessary to provide requested app features and support, maintain reliability and security, and comply with applicable legal obligations. Where data protection law requires consent for a particular activity, that requirement applies. Google's processing, storage locations and international transfer safeguards are described in the Google Privacy Policy.
7. Retention and deletion
- Local projects: delete named projects in “All saved projects”. Clearing the app's storage in Android settings removes local projects, recovery data and locally cached entitlement. Uninstalling the app removes its app-local data. Exported files must be deleted separately from the location you selected.
- Purchases: clearing local storage or uninstalling does not cancel a purchase or delete Google's transaction records. Purchase restoration may restore PRO. Google manages retention of its transaction and billing diagnostic records; the developer cannot delete those records from the app.
- Support: correspondence is kept for as long as necessary to handle and follow up on the request, resolve disputes and meet applicable legal obligations. You can request deletion of information held by the developer by emailing the contact above.
8. Security
Billing communications use encrypted connections. App-local information is protected by Android's application storage controls and your device security. No method of storage or transmission can guarantee absolute security.
9. Your rights
Depending on the law applicable to you, you may have rights to access, correct, delete, restrict or object to processing of your personal data, request portability and withdraw consent where processing relies on consent. Contact the developer for information held by the developer. For information held by Google, use Google's privacy and account controls. You may also lodge a complaint with your competent data protection authority. These rights are subject to applicable conditions and legal retention duties.
10. Updates
This policy may be updated when the app or its data handling changes. The current version and update date are published on this page.
