Privacy policy
1. What data we process
- User account – e-mail (sign-in name), full name, password (stored only as a hash) and the optional details you fill in: address, postal code, city, country, phone; the site language you registered in and the registration date.
- Licence – the status of your request, request/approval/rejection dates, the issued licence code and an optional administrator note. If the app verifies the code online, we store the time of the last verification, the number of verifications and an optional anonymous installation identifier the app sends.
- Reviews – if you write a review as a signed-in user, we store the name or nickname you entered, the rating, the text and the link to your account. Name and text are shown publicly after an administrator approves them; your e-mail is never published.
- Contact form – the name, e-mail and message you send us voluntarily. The message is not stored in the database; it is delivered to us by e-mail.
- Technical logs – the server keeps standard operational logs (request time, IP address, errors) to run the service and protect it against abuse, for at most 30 days.
The Deye-HomeMonitor app itself sends no data from your inverter to our server. All measurements stay on your device and in your home network. The only connection to our server is the optional licence code verification. The weather forecast and electricity prices are fetched by the app directly from Open-Meteo and OKTE according to your settings.
2. Purpose and legal basis
Account and licence data are processed to provide your account, issue the licence and make the download available (performance of a contract, Art. 6(1)(b) GDPR). Reviews are processed on the basis of the consent you give by submitting them (Art. 6(1)(a) GDPR). Contact form data are processed on the basis of our legitimate interest in answering your enquiry (Art. 6(1)(f) GDPR). Technical logs are processed on the basis of our legitimate interest in secure operation (Art. 6(1)(f) GDPR).
3. Retention
Account, licence and review data are kept as long as your account exists; on request we delete the account including the licence and reviews. Contact form messages are kept for at most 1 year after sending unless our correspondence requires longer retention. Technical logs for at most 30 days.
4. Who receives the data
E-mails (welcome, licence code, password reset, contact form messages) are sent via Gmail (Google LLC). The site and database run on third-party hosting in the EU. We do not pass data to any other third parties, do not use them for marketing and do not sell them.
