Our Promise
No ads. No data sharing. Ever.
Your thermostat knows when you wake up, when you leave, when you're home, and how you sleep. That's some of the most intimate data a device can collect. We will never sell it, share it, or use it to target you with advertising.
What your thermostat knows about you
A smart thermostat builds a detailed picture of your life. Your daily schedule. Whether you work from home. When the house is empty. How you sleep. These patterns, over months and years, are far more revealing than most people realise.
For companies whose business model depends on advertising, that data is valuable. SERA's business model doesn't.
How we're different
We charge for the product. That's the entire business model. Your data is not a revenue stream — it's yours, collected solely to make your thermostat work better for you.
- No advertising. SERA does not show ads, and we do not share your data with advertising networks or data brokers.
- No third-party analytics on your home data. We use anonymous, aggregated operational data to improve the product. Individual home data is never passed to third parties.
- No selling your data. We will never sell your personal or usage data to any third party, for any reason.
- Your data, exportable and deletable. You can export everything we hold about you, and request full deletion at any time.
Why this matters more than ever
Several major smart home platforms have changed their privacy policies after acquisition — data that was "never shared" became part of a larger advertising ecosystem overnight. We're an independent company with no such incentive.
This promise is written into our Privacy Policy and Terms of Service. If we ever considered changing it, existing customers would receive written notice at least 24 months in advance — and you'd be free to leave with your full data export.
