Privacy policy
Last updated November 13, 2026
This policy explains which personal data Kelvo processes, why, who we share it with and how you can exercise your rights, under Brazil's General Data Protection Law (Law 13,709/2018, LGPD).
1. Data controller
Kelvo and Enerseg are brands of AUSTON RODRIGO DAMAZIO LTDA, CNPJ 17.317.727/0001-08, which is responsible for the processing described here. For any privacy matter, including contacting our data protection officer, write to privacidade@enerseg.com.br.
2. What data we process and why
Website contact form
Name, business name, WhatsApp number or email, business type, any note you write and the page language. We use it only to answer your request and present Kelvo. Legal basis: pre-contractual steps at your request (art. 7, V).
To block bots, the form uses hCaptcha, which may collect technical data from your browser under the hCaptcha privacy policy.
Kelvo dashboard (customers)
- Account: company name, users' names and emails, and the password, stored only as a hash.
- Alert contacts: email addresses and WhatsApp numbers the customer registers to receive alerts.
- Sensor data: temperature readings, device identifier, firmware version, alerts and acknowledgments.
- Access logs: date, time, IP address and actions taken in the dashboard, for security and auditing.
We use this data to provide the contracted service: show readings, alert when the temperature leaves the range or a sensor goes silent, and keep the history. Legal basis: performance of a contract (art. 7, V), compliance with a legal obligation (art. 7, II) for access logs, and legitimate interest (art. 7, IX) for system security.
WhatsApp alerts
WhatsApp alerts are sent through Meta's WhatsApp Business Platform. We only message numbers the customer has registered in the dashboard, and the customer must register only people who agreed to receive these alerts. Messages are only about monitoring (alerts, reminders and temperature back to normal); we do not send advertising.
To deliver messages, Meta processes the phone number and the alert content. We receive from Meta the delivery status and replies to alerts, such as tapping "Confirm", which we record in the alert history. This data is not used for any other purpose. Meta also processes data under the WhatsApp Business terms and the WhatsApp privacy policy.
To stop receiving alerts, ask the person in charge at your company to remove the number in the dashboard, or write to privacidade@enerseg.com.br.
Browsing the website
The website uses no first-party cookies, analytics or advertising tools. Like any web server, ours temporarily logs the IP address and browser of visitors, for security and troubleshooting. The dashboard stores in the browser only what is needed to keep you signed in.
3. Who we share data with
We do not sell personal data. We share only what is necessary with suppliers who run the service on our behalf:
- hosting, cloud and network providers (servers, tunnel and connection protection);
- email and form delivery providers;
- Meta, for WhatsApp alerts;
- hCaptcha, to protect the form.
We may also share data when required by law or by an order from an authority.
Some of these suppliers process data outside Brazil. In those cases the transfer follows art. 33 of the LGPD, with suppliers that adopt contractual clauses and compatible safeguards.
4. How long we keep data
- Contact form submissions: up to 24 months after the last contact, if no contract follows.
- Customer data, readings and alerts: while the contract is active. After it ends, we delete or anonymize within 90 days, except what the law requires us to keep.
- Dashboard access logs: at least 6 months, as required by Brazil's Internet Civil Framework (Law 12,965/2014).
5. Your rights
At any time you may request: confirmation that we process your data, access, correction, anonymization, blocking or deletion of unnecessary data, portability, information on who we share it with, and withdrawal of consent where consent is the legal basis (art. 18 of the LGPD). Write to privacidade@enerseg.com.br; we answer within 15 days. You may also file a complaint with Brazil's National Data Protection Authority (ANPD).
6. How to request deletion of your data
- Email privacidade@enerseg.com.br with the subject "Data deletion".
- Tell us the email or WhatsApp number you want deleted and, if you are a customer, the company name.
- We verify the requester's identity and delete the data within 15 days, letting you know by email when done.
Dashboard users can also remove alert numbers and emails directly in the notification settings. Data the law requires us to keep is retained only for the legal period.
7. Security
We use encrypted connections (HTTPS and TLS), hashed passwords, per-company and per-user access control, and logging of dashboard actions. If a security incident may cause significant risk or harm to data subjects, we will notify those affected and the ANPD.
8. Changes to this policy
We may update this policy when the service changes. The date at the top shows the version in force; relevant changes will be emailed to customers.
