Terms and Conditions of Use

Last updated: September 10, 2026

Postventa is a ProtonLab platform for managing vehicle aftersales. These terms govern the use of the Postventa app, available for Android (phones and tablets) and Windows, by dealerships and repair shops (“the Dealership”) and their staff, and by vehicle owners (“the Owner”). By creating an account or using the app, you accept these terms.

1. The service

Postventa lets dealerships manage their appointment schedule, their vehicle fleet, their work orders with quotes, and communication with their customers. For owners it is a direct channel to their shop: see the next maintenance, book appointments, approve or reject quotes, chat, report faults and, if the shop offers it, request a tow.

Each dealership works in an isolated space: only its own staff can access its data.

2. Accounts

• You need an account to use Postventa. You can sign in with email and password, with your Google account or with your phone number.
• You are responsible for the accuracy of the information you provide and for keeping your access secure. Let us know if you think someone has accessed your account.
• You must be of legal age to use Postventa.

3. Dealerships and their staff

• The Dealership adds its staff and assigns each person a role (admin, service advisor, mechanic, front desk or tow driver); each role only sees and does what it is meant to. The Dealership is responsible for who has access and for removing it when someone leaves the shop.
• It is responsible for the customer, vehicle, order and payment data it records: for its accuracy and for having the right to record it.
• It decides which optional features it offers its customers (fault reports, towing, ratings and loyalty points). Whatever it turns off stops being available, and the system rejects any attempt to use it.

4. Owners

• The Owner links their vehicle using the shop's code and the license plate. The shop reviews the request and accepts or rejects it.
• The Owner is responsible for the truthfulness of the data they report, such as mileage or the description of a fault.
• When the Owner approves a quote in the app, the approval is recorded with date and time and tells the shop that they authorize the quoted work. If they reject it, the order goes back to the shop.

5. Acceptable use

You may not:

• Use Postventa for illegal or fraudulent purposes.
• Access, or try to access, the data of other dealerships or users.
• Bypass the security rules or use the platform in an automated way outside the app.
• Upload content that is offensive, illegal or that you do not have the right to share.
• Impersonate another person or another shop.

We may suspend or close accounts that breach these terms.

6. What Postventa does not do

• It does not repair vehicles or set prices. ProtonLab provides the tool; the work, prices, warranties, delivery times and appointment availability are decided by each dealership. Any disagreement about them is settled between the Owner and the Dealership.
• It does not process payments. Payments recorded by the shop are a record of what it received, not a payment made through the app.
• It does not run loyalty points or towing. Each dealership offers them, and their conditions depend on the dealership.
• It is not an emergency service. In an accident or if anyone is at risk, call your country's emergency services.

7. Content, data and ownership

• The data, messages and photos you upload remain yours or the dealership's. You give us permission to store, process and show them to the right people, solely to provide the service.
• How we handle personal data, who it is shared with and how to delete your account is explained in the Privacy Policy.
• The app, its design and its code belong to ProtonLab. You may use it, but not copy, modify or resell it.

8. Availability

Postventa runs on Google Cloud and Firebase infrastructure. We do our best to keep it available and working well, but we cannot guarantee it will be free of interruptions or errors, and we are not liable for outages of those providers or for connectivity problems on your device. The service is provided “as is”.

9. Liability

To the extent permitted by law, ProtonLab is not liable for indirect damages or for decisions that dealerships or owners make based on information in the app. Maintenance reminders are calculated from the recorded data and are for guidance only: they do not replace the manufacturer's or the shop's recommendations.

10. Closing your account

You can stop using Postventa at any time and ask us to delete your account, as explained in the Privacy Policy.

11. Changes to these terms

We may change these terms. We will post the new version on this page with its date, and significant changes will be announced in the app or by email to dealerships. If you keep using Postventa after a change, you accept it.
