Tierce
A PRIVACY-FIRST DREAM JOURNAL THAT KEEPS EVERYTHING

Speak the dream. Keep every detail of it.

Speak the dream before it thins out and Tierce holds every detail — the stairs, the weather, the word you almost forgot. Then a quiet, private place to sit with what it might mean — the interpreter runs on the phone, and nothing you dream ever leaves it.

runs on the phone, offline.

How it works

01

Speak it, don't type it

Talk with your eyes shut — one tap to start, one to stop. Tap any word to fix it and keep going — the recording resumes from your cursor, so nothing gets overwritten.

02

Nothing is dropped

The transcript keeps your own words. Around it Tierce records the weather, the season, the moon, whether you were home or away — the details you'd never think to write at 6am.

03

Then ask what it means

A local AI reads the dream on the phone — offline, no account, nothing uploaded — and answers in plain language, ending in a question back to you. Answer it and the reading goes deeper.

NOTHING TO FILL IN

You just woke up. This isn't the moment for a form.

TIERCE ASKS FOR ONE THING

Just the dream. Say it half-asleep, eyes still shut — Tierce fills in the weather, the season, the moon on its own, and asks nothing back.

There is more to write down if you're woken at the right minute.

Optional, and read-only: with Apple Health, Tierce learns where your REM ends and wakes you at the edge of it instead of through the middle. A Tuesday sleeps differently from a Saturday, so it keeps them apart.

THE WAKE WINDOW

You give a range. Tierce picks the minute inside it where REM lets go — the moment the dream is still whole enough to say out loud. And it shows you, on your own nights, whether that works: how often a dream survives a wake inside light sleep.

WHAT IT SAYS BACK

One thread, and every night strung on it.

Nothing is a card floating loose. Each dream is a bead on the same line — the ones you spoke, and the mornings when nothing surfaced. Ask, and Tierce reads one back to you, then asks you a question.

A READING
LOCAL AI · OFFLINE

A rising you don't resist. The staircase is new, so the way up is something you are only now admitting exists — and the water arrives warm, which is not how fear arrives.

Three of your last nine dreams end at a threshold you don't cross.

Generated by a local AI, on your phone. A reading, not a diagnosis — and never a substitute for care.

Written here, and nowhere else.

The archive is local

Recordings, transcripts and readings live on the phone, and in your own iCloud if you want a backup. There is no server holding your dreams because there is no server.

Motifs, not metrics

From the second week your nights start talking to each other — the people who return, the weather that matters, the words that keep coming back. Nothing is scored, no streak to keep — and when a pattern doesn't hold up, Tierce keeps it to itself.

What stays on your phone

Dream recordings, transcripts, the sleep records read from Apple Health and every interpretation are stored on the device and, if you enable backup, in your own iCloud Drive. We have no access to either. Interpretation always runs on the phone — there is no cloud analysis, and nothing you record is ever uploaded.

Interpretation

Readings are produced by an AI model running on your device — the system model, or one you download. The text of your dream is never sent to us or to any third party, we never see the reading, and your dreams train nothing. Each reading is labelled as AI-generated, in the app and in exported files.

Apple Health

Tierce requests read-only access to sleep analysis — one category, nothing else — after you save your first alarm. It never writes to Health, and the app works — less precisely — if you decline.

What leaves the phone

Never a dream — and a short list of technical requests: the model download you ask for, a daily check of a static model-catalogue file, two coordinates rounded to about 11 km for the night’s weather — with your permission, and only then — and the version check and push registration through Google. Two more things can leave, and only if you say yes: crash reports scrubbed of anything resembling content, and a few anonymous counters. We ask once, at the end of setup; the switch starts off, and a phone that never turns it on sends neither. No ads, no cross-app tracking, no advertising profile.

What we do collect

Your email address, if you subscribe to the letter, used only to send it. If you agree: the technical crash reports above, and counters that add 1 to a number — what people came for, how far they got through setup, whether a reading was any good. They count a population, never a person: no identifier travels with them, and nothing you do in the app afterwards is measured at all. Whether a purchase is active, validated through RevenueCat under a random identifier — payment itself is handled by Apple; we never see your card. Optional website analytics, described in the cookie policy.

Your rights

Under the GDPR you may request access to, correction of, or erasure of anything we hold, and you may object to processing or ask for it to be restricted. Write to privacy@tierce.app and we answer within thirty days. Deleting the app removes the on-device archive; deleting the iCloud backup removes the copy there.

Children

Tierce is not intended for anyone under sixteen, and we do not knowingly collect data from them.
