Vendaê Privacy Policy
Last updated: October 25, 2026
Vendaê is an app for small businesses to record sales, stock, customers and receivables. This policy explains, in plain language, which data the app uses and how it is handled, in line with Brazil's General Data Protection Law (LGPD, Law No. 13,709/2018).
1. Who is responsible
Vendaê is developed and maintained by WAS Sistemas & Serviços (CNPJ 46.377.981/0001-91), run by Wellington A. Silva (the "developer"). Because the data stays only on your device, you control and are responsible for the information you enter, including your customers' information. For any question about this policy, write to us at contato@wassistemas.com.
2. Which data the app uses
All the information below is typed or chosen by you inside the app:
| Data | What it is for |
|---|---|
| Your name and phone (optional), entered on first launch | Identify who uses the app on this device. |
| Your business details: name, address and tax ID (optional) | Appear on the PDF receipts you issue. |
| Customer details: name, phone, email, address, tax ID (if you enter them) | Customer records, sales and collections. |
| Products, stock, sales, payment methods, amounts and notes | Record sales and track stock, receivables and payables. |
The app does not request location permission, does not access your contacts, microphone or messages and does not collect advertising identifiers.
3. Where the data is stored
Data is kept in a local database inside the app's private storage on your device. It is not sent to any Vendaê server. If you uninstall the app or clear its data, the information you entered is erased from the device and cannot be recovered by us.
Please note: Android may offer Google's automatic backup for your device. If you keep it turned on, part of the app's data may be copied to your Google account, according to Google's own settings and policy. You can manage this in your device settings.
4. Permissions used
- Phone, WhatsApp and maps: when you tap a customer's contact actions, the app opens your device's dialer, WhatsApp or map with their phone number or address. From there, those apps' own policies apply.
5. Data sharing
Vendaê does not share, sell or transfer your data to third parties. Sharing happens only through an action of yours, when you tap “Share” on a PDF receipt. In those cases you choose the destination app (email, WhatsApp, etc.) and the content then follows that service's rules. Inform your customers and obtain their consent when necessary.
6. Ads, tracking and third-party services
The app shows no ads, uses no analytics or tracking tools and does not integrate third-party services that collect usage data.
7. Your rights (LGPD)
Because the data stays on your device, you can at any time view, correct or delete the information directly in the app or by removing the app. If you have any question about your rights as a data subject, write to contato@wassistemas.com.
8. Security
Data is kept in the app's protected storage, accessible only to the app itself. We recommend keeping your device screen lock on and your system up to date. The developer has no access to the data stored on your device.
9. Children and teenagers
Vendaê is intended for professionals and businesses and is not directed at people under 18.
10. Changes to this policy
This policy may be updated to reflect changes to the app or the law. The date of the last update appears at the top of this page. If there is a relevant change, it will be announced on the app's store page.
