Who we are
Wattlark is a product concept presented by UnitOne AI (unitoneai.com). The service is not yet commercially available.
What we collect
- Early-access and contact forms: name, email, home type and message.
- Accounts: name, email, a salted argon2id password hash, household details you enter, and the activity log of your actions.
- Energy data: in the demo this is generated by a simulation, not read from your meter.
How we use it
To run the demo, answer messages, and secure accounts. We do not sell data, run advertising trackers or use third-party analytics in this build.
Cookies
Essential cookies keep you signed in and secure: a session cookie (httpOnly), a CSRF token and your cookie choice. One optional preference cookie remembers your daylight or evening theme and is only set if you allow preferences. No analytics or tracking cookies are used. Change your choice any time with Cookie settings in the footer.
Your choices
Signed-in users can export their data from Settings. To ask for deletion of demo data, contact us through unitoneai.com.
Retention and security
Demo data is kept until the demo database is reset. See Privacy and security for the measures implemented today.
Changes
We will update this page, and its date, if our practices change before launch.
