Privacy Policy
Last updated: October 13, 2026
Post Somnum is a dream journal made by Zachary Kashef ("I", "me"). This policy explains what happens to the information you put into the app. In short: your dreams stay on your iPhone, I don't collect anything, and something leaves your iPhone only when you choose to send it.
Who Is Responsible
Zachary Kashef, support@postsomnum.com
What I Collect
Nothing. Post Somnum has no account, no server of its own, and no analytics, advertising, tracking or crash-reporting tools. I can't see your dreams or anything else you enter, and I don't receive any information about how you use the app.
What the App Stores on Your iPhone
- Your dreams and everything you add to them: titles, text, dates, moods, lucid status, tags, music, People, Places & Things, how vivid and long a dream felt and whether it's recurring, the sleep you log for each night (sleep quality, time asleep, and bed and wake times, plus sleep stages when it comes from Apple Health), and saved AI chats.
- Photos and voice notes you add to dreams. Photos are chosen with Apple's photo picker, which gives the app only the ones you pick, or taken with the camera, and a resized copy without location data is kept inside the app. Voice notes are recorded and kept inside the app. Both are deleted with their dream.
- Your settings: your moods, font, background photos you pick (a resized copy kept inside the app), reminder time, export choices, your AI provider and model, and which calendars Calendar Context uses.
- An API key for Claude or OpenAI, if you add one, kept in the iOS Keychain and locked to this iPhone.
- The date you accepted the Terms of Use and the AI Dream Analysis acknowledgment.
This information stays on your iPhone. Like most apps' data, it's included in your iPhone's own backups (iCloud Backup or a computer) if you have backups turned on; Apple handles those backups under its own privacy policy. Deleting the app removes everything it stored.
Apple Health
Reading sleep from Apple Health is optional and off until you turn on Fill Sleep from Apple Health in Settings and allow it in iOS's permission sheet. The app then reads only your sleep analysis (time asleep, time in bed, time awake and sleep stages) and never writes anything to Apple Health. What it reads is used only to fill in the sleep for the nights in your journal and in your Statistics, and is saved with your entries on your iPhone. It's never sent to AI providers, to me, or to anyone else, and never used for advertising; it leaves your iPhone only inside an export or a shared dream that you make yourself. You can turn it off in Settings › Apple Health, and remove the app's access in the Health app (your picture › Apps › Post Somnum).
Your Calendar (Optional)
Calendar Context is off unless you turn it on in Settings and allow calendar access. When it's on, the app reads the title, start and end time, and calendar of the events in the calendars you choose, on your iPhone, to show them beside your dreams and to find patterns between your days and your dreams. It only reads: it never adds, changes or deletes events, and it doesn't read event notes, locations or invitees. Events are read each time they're shown and aren't saved in your journal. You can turn Calendar Context off in Settings at any time, and remove the app's calendar access in your iPhone's Settings.
When Information Leaves Your iPhone
Only when you choose:
- AI Dream Analysis with Claude or OpenAI. This is off unless you turn it on and add your own API key. When you chat about a dream, that dream (and, if you choose, the other dreams from the same night) and your chat messages are sent straight from your iPhone to Anthropic or OpenAI under your own account with them (never sleep from Apple Health), and their privacy policies apply (Anthropic, OpenAI). Nothing passes through me. If you also turn on Include Calendar Events in AI Chats, the titles and times of your calendar events from the day before and the day of that dream are sent with it. If you choose Apple's on-device model instead, everything stays on your iPhone.
- Sharing and exporting. A dream, chat or export leaves the app only when you share or save it, and goes only where you send it.
- Rating the app. Rate App opens an email draft that's sent only if you send it yourself.
- Purchases. If you buy anything in the app, Apple handles the payment. I receive only Apple's sales reports, not your name or payment details.
The optional morning reminder is scheduled on your iPhone and never includes anything you've written.
Photos and voice notes are never sent to Anthropic, OpenAI or anyone else, and aren't included in exports or in a shared dream's text. One leaves your iPhone only if you share that photo or voice note yourself. Transcribing a voice note into text happens on your iPhone with Apple's on-device speech recognition; the first time, iOS may download Apple's speech model for your language, but your recording isn't sent.
Your Rights
I don't hold any of your personal data, so everything is already under your control on your iPhone: you can edit or delete any dream, export your journal at any time, and delete the app to remove everything.
If you live in the EU, EEA or UK, data protection law (GDPR) gives you the right to access, correct, delete, restrict or object to the processing of your personal data, the right to data portability, and the right to complain to a data protection supervisory authority. For anything you've sent to Anthropic or OpenAI, contact them directly.
Children
Post Somnum isn't intended for children under 13. AI Dream Analysis with Claude or OpenAI needs an account with those companies, which set their own age requirements.
Changes
If this policy changes, the new version will be published here and in the app with a new date.
