Lucidory Privacy Policy

Last updated: 8 October 2026

This policy explains what personal information the Lucidory: Dream Journal iOS app (“Lucidory”, “the App”) collects, why, and what we do with it. Lucidory is a dream journal: you write the dreams you remember, mark the lucid ones, notice the signs that return and keep a daily reality check. The App is published by DreamApp Ltd, a private limited company registered in England and Wales under company number 12692529, with its registered office at 17 Kings Gardens, Walton-on-Thames, KT12 2DW, United Kingdom (“DreamApp”, “we”, “us”).

This policy covers Lucidory only. DreamApp’s own app and website have their own privacy notice.

1. The short version

What you write in Lucidory stays yours. We use it only to run the App for you.
We do not sell your information, we do not show ads, and we do not track you across other apps or websites.
Your writing is never included in any dataset we license or sell, and it is never used to train AI models.
You can ask us to delete everything at any time by writing to support@dreamapp.io.

2. Information we collect

What you give us. This is the first name you give us, your onboarding answers, the dreams you write, the signs and lucid marks you add, your answers to the follow-up questions, your reality-check log and the messages you send to Nyx. If you choose to, you can also give us an email address so we can send you a few short letters. Email is optional and you can skip it.

What the App records automatically.

A random identifier. The App creates a random identifier on your device so your settings and entries can be backed up and restored. It is not your Apple ID or your device’s advertising identifier, and we do not use it to track you.
Subscription status. Apple tells the App whether you are on the free tier, in a trial or subscribed. We never see your payment card or your Apple ID.
Usage events. Anonymous events, such as which screen was opened or that a button was tapped, so we can fix problems and improve the App. These events never contain what you write.
Crash reports. If you allow it in iOS settings, Apple shares anonymous crash reports with us.

We do not collect your location, contacts, photos, health data or advertising identifier.

3. How we use it

To run the App: keep your entries, show your history and restore it if you reinstall.
To answer you in the chat: when you message Nyx, your message and the recent conversation are sent to our server and passed to our language-model provider to write the reply, together with context the App adds so the reply fits, such as tonight’s card or dreams, your first name and your quiz result. Your date of birth never leaves your device.
To read replies aloud: when you tap Listen (a Premium feature), the text of that one reply from Nyx is sent to our voice provider to turn it into speech. A reply can repeat details you shared in the chat, such as your first name; nothing else you wrote is sent. Our voice provider is reached through our own server, so it never receives your device's address.
To share a result card, only when you tap Share: we create a public link that shows the name you entered and the result. If you read a card for someone else, please only use their name with their agreement.
To send the optional letters you asked for, and service messages about your subscription.
To find and fix bugs and understand which parts of the App are used.
To meet legal and accounting obligations.

4. Lawful bases (UK and EU)

We rely on contract (to provide the App and any subscription you buy), legitimate interests (to keep the App working, secure and improving), consent (for optional email and notifications, which you can withdraw at any time) and legal obligation (for records we must keep).

5. Who we share it with

We share information only with the service providers that run the App for us, under written contracts that limit their use of it to providing their service:

Provider	What they do	Where
Apple Inc.	App Store, subscriptions, notifications, crash reports	United States
Google Cloud (Google LLC)	Hosts our servers and the backup of your entries	Belgium (europe-west1)
Anthropic PBC	Writes Nyx’s chat replies	United States
Hume AI, Inc.	Reads Nyx’s replies aloud when you tap Listen	United States
PostHog Inc.	Anonymous usage analytics	United States
Resend, Inc.	Sends the optional letters, only if you gave us an email	United States

Anthropic processes chat messages under terms that do not allow it to use them to train its models. We may also disclose information if the law requires it.

6. International transfers

Some providers are in the United States. Where your information leaves the UK or EEA, we rely on approved safeguards such as the Standard Contractual Clauses and the UK International Data Transfer Addendum.

7. How long we keep it

Your entries, settings and chat history: while you use the App, and for up to 24 months after your last use, then deleted. Sooner if you ask.
Shared result-card links: 90 days, then the link stops working and its content is deleted.
Email address: until you unsubscribe or ask us to delete it.
Subscription records: 7 years, for UK tax and accounting rules.
Anonymous usage events: up to 12 months.

8. Your rights

You can ask us for a copy of your information, to correct it, to delete it, to receive it in a portable format, or to restrict or object to how we use it. UK users can complain to the Information Commissioner’s Office (ico.org.uk); EU users to their local data protection authority. California residents have the right to know, delete and correct, and the right not to be discriminated against; we do not sell or share personal information as the CCPA defines it.

To use any of these rights, write to support@dreamapp.io.

9. Children

Lucidory is not directed at children under 13 (16 in some EU countries), and we do not knowingly collect their information. If you think a child has used the App, write to us and we will delete their information.

10. Security

Information is encrypted in transit and at rest, access to our servers is limited, and each app has its own credentials. No system is perfectly secure; if a breach affects you, we will tell you as the law requires.
