Terms of service

1What Sentinela PTT is

This English version is provided for convenience; in case of any discrepancy, the Spanish version prevails.

Sentinela PTT is a push-to-talk radio service over the internet: it lets the people in your company talk to each other at the press of a button, from an app on their phone. It is provided by Enrique Garza Cantu, an individual doing business under the trade name Sentinela, located at Río Álamo No. 329, Col. San Francisco, ZIP 87350, H. Matamoros, Tamaulipas, Mexico («Sentinela»). By subscribing to or using the service, you (the company or person subscribing, «the customer») accept these terms.

If you signed a contract or quote with different conditions, the signed document prevails on those conditions.

2Plans

Prices are in US dollars, plus applicable taxes. Billing is per active user: each person added to your radio.

The dashboard and recording in the Radio + Map plan will be available very soon. Until they are ready, that plan is billed at the Radio plan price (US$5.99 per month or US$59 per year per user). Once they are ready it moves to its US$9.99 price, and we will notify you at least 30 days in advance, as described in the payments section.

3Free trial

• You can try the Radio plan free for 7 days, with up to 5 users, by signing up on this website. No credit card required.
• The trial information and QR codes are sent to the email you register. One trial per company.
• When the 7 days end, if you subscribe, you keep the same server and the same codes. If you do not, the trial switches off on its own, nothing is charged and the trial server is deleted after 15 days.
• These same terms apply during the trial, including proper use of the service. We may refuse or end a trial if the sign-up data is not genuine or if it is used against these terms.

4The app map and the dashboard

In all plans, while a person has their shift active in the app, the rest of your team can see in the app where they are and their work status, and receives their emergency (SOS) alerts.

In the Radio + Map plan, you and the people you authorize also log in to a dashboard from a computer, with a username and password. There you can see:

• Where each person on your team is right now, while their shift is active in the app.
• What they are working on: each person marks in the app whether they are available, on the way or on a job.
• Who is talking on the radio, the recordings of conversations with their text, and the emergency button alerts.

Location depends on the phone's GPS and data connection: indoors, in basements or in areas without signal it may be approximate or delayed. The work status («on a job», «on the way») is the one each person selects; Sentinela does not verify it.

You decide who in your company has access to the dashboard and are responsible for keeping those passwords safe. If someone stops working with you, ask us to remove their access.

5Setup and users

• To set up the service we ask for your name or company name and a contact person; customers in Mexico who need an invoice (CFDI) also provide their tax data.
• For each person you add we give you a personal QR code: scanning it sets up the app. That code works like a key: do not share or publish it.
• You can add or remove people whenever you want. When you remove someone, their code stops working immediately. Additions and removals are reflected in the charge for the next billing period.
• You must inform each person you add how the radio works, that their location is shared with the team while their shift is active, and, in the Radio + Map plan, that their conversations are recorded. A template notice for them is included in the Spanish privacy notice.

6Payments and invoicing

• The service is paid in advance, monthly or for a full year. The annual plan is roughly 10 months' price for 12.
• Each period we email you your invoice or receipt, with the payment due date and payment details.
• Customers in Mexico can get a tax invoice (CFDI) by providing their tax data.
• If we change prices, we will notify you at least 30 days in advance. An annual plan already paid keeps its price until it ends.

7Non-payment: suspension and reactivation

• If the due date passes without payment, we will notify you by email before suspending.
• Suspension takes effect 5 days after the due date. While suspended, your company's radio stops connecting for all your users and the dashboard is unavailable. Nothing is deleted: your users, channels and recordings are kept.
• Once payment of everything overdue is recorded, the service reactivates on its own and your users log back in with the same QR codes, with no setup needed.
• If you need a few more days to pay, contact us before the suspension: we can grant an extension.

8Proper use of the service

Sentinela PTT is for coordinating your company's work. It may not be used to:

• carry out illegal activities, threats or harassment, or transmit content that harms others;
• monitor or record people without informing them, or outside their working hours;
• resell the service or add people outside your company without our agreement;
• attempt to access other customers' servers or disrupt the service.

If we detect such use, we may suspend the service and, if serious, terminate it, informing you of the reason.

9What the service needs and its limits

• It works on Android phones with the app indicated by Sentinela, and needs mobile data or Wi-Fi. You provide the phones and the data plan; Sentinela does not charge for the data the app uses.
• Quality depends on each phone's signal and data connection. Without internet, the radio does not work.
• We work to keep the service available at all times, but there may be interruptions due to internet or provider failures or maintenance. Scheduled maintenance is announced in advance.
• Sentinela PTT does not replace 911 or emergency services. The emergency button (SOS) alerts your team (and your dashboard, if you have one); Sentinela does not answer it or dispatch help, unless you separately subscribe to our monitoring center.
• Sentinela is not responsible for what is said over the radio or for the decisions your company makes based on the information in the app or the dashboard.

10Privacy and your data

Each company has its own radio server; a personal QR code is required to connect. Sentinela does not listen to your conversations or use your radio's information for its own purposes. The details (what data we process, how long we keep it and how to exercise your rights) are in the privacy notice.

11Cancellation and termination

• You can cancel at any time by notifying us in writing (email or WhatsApp). There is no minimum term or penalty.
• On the monthly plan, the service continues until the end of the period already paid. On the annual plan, the service continues until the end of the paid year and unused months are not refunded.
• If you want to keep recordings, ask us for them before the cancellation date.
• When the service ends, your company's radio server is deleted, with all its accounts, recordings and locations; they cannot be recovered.
• If the service is terminated for non-payment, the overdue amounts remain payable.

12Changes to these terms

If we change these terms, we will publish the new version at https://sentinelaptt.com/en/terms (Spanish version at https://sentinelaptt.com/terminos) with its date and, if the change affects you, we will notify you at least 30 days in advance. If you do not agree, you may cancel before it takes effect.
