Our mission
Sereneo is a quiet place to journal and check in on how you feel. It gently reflects your patterns back to you — without judgment, scores, or pressure — one day at a time.
Inside Sereneo
Three things, done carefully — instead of a dashboard of features competing for your attention.
Journal
Write as much or as little as you like. Every entry saves to your device the moment you write it, so nothing waits on a connection and nothing gets lost.
Check in
Quick mood check-ins and stress notes, with a tag or a sentence if you want one. Small enough to do on a hard day, and never nagging you when you skip one.
Your Wrapped
Every so often, Sereneo gathers what you've written into a quiet summary of how your weeks have actually gone. A gift, not a report card — and an AI reflection only if you switch it on.
Sereneo handles what the GDPR calls special-category health data. It is built that way from the ground up, rather than as a policy page written afterwards.
Encrypted
Every entry, with a key unique to you
No ads, ever
No trackers, no data sold, no third-party SDKs
Yours to take
Export anytime, delete your account in a few taps

Sereneo is still being built, carefully. Leave your email and you'll hear from us when it opens — no drip campaign, no countdown, no launch hype.
What you'll get on day one
Pricing hasn't been decided yet. When it is, you'll hear it from us before you're ever asked to pay for anything.
One email when Sereneo opens. Nothing else, and you can leave any time.
Questions
The things people most want to know before they trust an app with how they feel.
No. Sereneo is a self-reflection tool. It doesn't diagnose, treat, or prescribe, and it isn't a crisis service. If you're struggling, please talk to a real person — in Norway, Mental Helse is on 116 123, and the emergency number is 113.
No. Journal text and any AI reflection are encrypted with a key unique to you. Delete your account and that key goes with it, immediately and for good.
No. AI reflections are a separate, explicit choice that starts switched off. Say no, or change your mind later, and the rest of Sereneo works exactly the same.
Never. Your entries are not used to train anyone's model — ours or a third party's. When an AI reflection is generated, it's labelled as AI and it isn't retained for training.
Yes. Every entry saves to your device the moment you write it, so nothing waits on a connection and nothing gets lost if you're offline.
Pricing hasn't been decided yet. Sereneo is pre-launch, and when there is something to announce you'll hear it from us before you're ever asked to pay for anything.
It's coming to iPhone first, in English and Norsk. There's no date yet — join the waitlist and you'll get one email when it opens.
