Legal document

Privacy Policy

Version dated July 22, 2026.

1. Who we are

Controla Venda is an Android app developed by Silvana Betoldo under the Criativament brand. For privacy matters, email [email protected].

2. How the app works

The app works primarily offline, with no login, dedicated account, data server, synchronization, or remote database. The information you enter is stored in the device's local SQLite database.

3. Data entered by the user

You may record information locally, including:

business or professional details, such as name, contact information, address, and CNPJ;
products, prices, stock, and optional images;
customer names, sales, items, amounts, payments, installments, and notes;
reasons for archiving products and canceling sales.

This data is used to perform the functions requested within the app itself. The developer does not automatically receive the contents of the local database.

4. Device permissions

Camera and photos: used only when you add an image to a product.
Files and documents: used to export or import backups, PDFs, and CSVs at your request.
Internet: may be used to open this documentation, access Google Play services, and load ads when present.

5. Backups and sharing

Exported files may contain business and personal data you have entered. You choose where to save or share these files and are responsible for protecting them, controlling access, and deleting unnecessary copies.

6. Google Play, purchases, and ads

Versions distributed through Google Play may use Google services to process a Premium purchase, restore usage entitlements, prevent fraud, and display ads in the free version. These services may process device identifiers, purchase information, IP address, diagnostics, and interactions according to Google's policies. Controla Venda does not receive complete card details or payment credentials.

6.1. Access to this website

This website's hosting service may record technical data needed to deliver and secure pages, such as IP address, date, time, browser, and error logs. We use Google Analytics to measure visits and understand, in aggregate, how pages are used. This service may use cookies and process identifiers, device data, approximate IP address, and browsing information according to Google's policies. The website has no registration or form of its own.

7. Retention and deletion

Local data remains on the device as long as the app and its data are kept. Deletion may occur by clearing app data or uninstalling. Archived products and canceled sales remain in history as part of the system's functionality. Backup files must be deleted separately by the user.

8. Security and user responsibility

We adopt measures appropriate to the app's local architecture. Even so, no device is completely immune to loss, unauthorized access, or failure. We recommend a screen lock, Android updates, and backups in a trusted location.

9. Children and adolescents

The app is a business tool and is not directed at children. We do not knowingly collect children's data for profiling.

10. Rights and contact

Because operational data stays on the device itself, you can directly access, correct, export, and delete it locally. Privacy questions may be sent to the email address provided in this policy.

11. Changes

This policy may be updated to reflect legal or functional changes. The current version will be published on this page with its update date.

Applicable prices and conditions are those presented in the official purchase flow.

5. Purchase, restoration, and refund

Purchases, payments, cancellations, and refunds follow Google Play's rules. Restoration depends on the Google account that made the purchase, store availability, and validation of the usage entitlement. Refunds, chargebacks, or revocation may remove Premium access.

We strive to keep the app functional, but do not guarantee uninterrupted operation on all devices, manufacturers, or Android versions. Updates may be needed for security, compatibility, and compliance with Google Play rules.
