How we protect your dreams
A dream journal holds some of the most private writing a person does. Before launching Nyxwyn we carried out a formal privacy impact assessment: a structured look at what could go wrong with your data, how badly it could hurt you, and what we do about it. The law asks for one when an app handles sensitive information with new technology. We would have done it anyway. Here is what it found and what we promise.
We treat everything you write as sensitive
Dreams touch on health, relationships, sexuality and belief. We don't try to decide which entries are sensitive. We treat all of them as if they were, and we ask for your explicit agreement before storing anything.
Your journal stays in Europe and stays yours
- Your dreams and your Analytical Journal are stored in Frankfurt, Germany.
- Every record is locked to your account. The database itself refuses to show one person's entries to anyone else, and we test that rule automatically.
- Everything is encrypted on the way to our servers and while stored.
- You can lock Nyxwyn with Face ID, your fingerprint or your phone's PIN, and add two-step sign-in, so a borrowed or lost phone doesn't open your journal.
- We never sell your data, show you ads, or let anyone train AI on your dreams.
AI only touches your dreams if you say so
- Theme identification is off until you switch it on, and you can switch it off any time.
- When it is on, each dream you seal is sent on its own, with your theme list, to identify the themes in it. Your name, email and account number are never sent with it.
- Reports are built from themes, counts and a few words quoted from your dreams, never the full text.
- Your Analytical Journal is never sent to any AI.
- You can mark any dream as private. A private dream is never sent to AI, even when theme identification is on, until you change that one dream yourself.
- Nyxwyn identifies themes. It does not interpret your dreams or tell you what they mean. That part is yours.
You can leave, completely
Delete your account in Settings and your journal is erased from our database immediately and from our backups within 7 days. Cancelling your subscription does not delete anything; your journal stays readable and yours.
What we watch for, and what we do about it
| What could go wrong | What we do |
|---|---|
| Someone reads your journal who shouldn't | Per-account locks tested on every change, keys kept off your phone and out of our code, alerts when your password or email changes, an independent security review before launch |
| The AI service keeps or leaks what it was sent | Opt-in only, one dream at a time, no identifiers, a provider that doesn't train on it and deletes it within 30 days |
| Your journal is lost | Managed daily backups; nothing is deleted except by you |
| Themes are taken as a diagnosis | We say plainly that Nyxwyn is not health advice, and we never label a dream as meaning anything |
| A future feature uses your dreams in a new way | We repeat this assessment and ask for your agreement first |
If something ever goes wrong
If a security problem ever puts your data at risk, we will tell you directly and promptly, say what happened and what we are doing, and notify France's data-protection authority (CNIL) as the law requires.
