Privacy Policy

1. Controller and contact

The controller for this website is the website owner of Plant.

Contact: plant@sneferu.de

If this website is used commercially or by multiple people, add the full legal name, postal address, and responsible contact details here.

2. Purpose of the website

This website is a private plant monitoring and watering dashboard. It is used to view plant status, ESP/device data, sensor values, water tank information, activity logs, alerts, and watering controls.

3. Data processed

The website may process the following data, depending on enabled features:

• Login and account data, such as username, email address, password hash, roles, and session status.
• Plant data, such as plant names, photos, plant notes, sensor assignments, and care settings.
• ESP/device data, such as API key status, firmware version, last seen time, Wi-Fi RSSI, voltage, battery, tank level, pump state, sensor readings, and command status.
• Operational data, such as activity logs, alerts, watering history, blocked-command reasons, calibration values, and backups.
• Technical server data, such as IP address, browser information, request time, error logs, and security logs.

4. Legal basis

Processing may be based on legitimate interest in operating, securing, and maintaining the private dashboard, contract or user-account administration where accounts are provided, and consent where optional features require it.

5. Cookies and local storage

The website uses necessary cookies for login sessions and WordPress security. These are required for the private dashboard to work.

If analytics, marketing tools, external media, maps, fonts, or non-essential tracking are added later, a consent solution should be added before those tools are activated.

6. Hosting and processors

The website is hosted by the selected web hosting provider. The hosting provider may process server logs, database data, uploaded files, backups, and technical metadata to operate and secure the website.

Add your hosting provider name and data processing agreement details here if the website is used beyond purely private use.

7. ESP/device communication

ESP devices send sensor and system data to the website API. The website stores this data so the dashboard can show current and historical plant status. Device API keys should be kept private.

8. Retention

Data is kept only as long as needed for dashboard operation, troubleshooting, security, backups, and legal obligations. Activity logs and backups should be reviewed and deleted when no longer needed.

9. Your rights

Depending on applicable law, users may have rights to access, correct, delete, restrict, object to processing, receive a copy of their data, and withdraw consent where processing is based on consent.

10. Security

The website should be protected with HTTPS, strong passwords, limited admin access, private API keys, regular updates, and backups. Manual watering commands should only be available to trusted users.

11. Changes

This privacy policy may be updated when features, hosting, devices, analytics, account roles, or legal requirements change.

Plant Assistant

The local Plant Assistant answers questions by reading current Plant Watch data already stored on this WordPress site, such as ESP status, tank level, alerts, and plant readings. In this version, the assistant does not send messages to an external AI provider and does not store chat messages.
