Terms & conditions

These terms govern the Tierce iOS application and the website tierce.app. They are written to be read. The short version: the app is yours to use, your dreams are yours and never reach us, the interpretations are a machine’s reflections and not advice, and if you take what the machine wrote and publish it somewhere, that is your act, not ours.

1. Who provides the service, and agreement

The app and the site are provided by Francesco Dallatorre, a sole trader established at Via Gaetano Modonesi 24, 29122 Piacenza, Italy — VAT IT01934820331 (“Tierce”, “we”). By installing or using the app, or using the site, you agree to these terms. If you do not agree, do not use them. You must be at least sixteen years old.

2. What Tierce is

Tierce is a dream journal. It records a dream in your voice or your words, transcribes it on the device, keeps it with the night’s context (sleep, weather, moon), and offers an interpretation produced by an AI model that runs on your phone. Some features are free; others are unlocked by a subscription or by a one-time lifetime purchase (section 9).

3. Your content stays yours — and never reaches us

Everything you put into Tierce and everything the app produces from it on your device — recordings, transcripts, dreams, tags, answers, interpretations (“your content”) — is yours. You grant us no licence over it, because we never receive it: the app has no server for it and we hold no copy. It follows that we cannot see, moderate, restore or recover your content. Keeping the backup enabled, or exporting your archive, is how you protect it; losing a phone with no backup loses the dreams on it. Section 11 sets out what that means, and what can never be recovered.

You are solely responsible for your content and for what you do with it outside the app.

4. AI interpretations — what they are and what they are not

Interpretations, titles, keywords and follow-up readings are produced by a probabilistic language model. They can be wrong, incomplete, generic or unsettling. They are offered for reflection only.

• They are not advice — not medical, psychological, psychotherapeutic, legal or financial advice, and not a diagnosis of anything. Tierce is not a medical device and does not treat, diagnose or prevent any condition. If you are concerned about your sleep or your mental health, speak to a professional.
• You must not rely on an interpretation for any decision that matters without verifying it by your own judgement.
• Each interpretation is labelled as machine-generated in the app, and exported files carry a machine-readable notice, in line with Article 50 of Regulation (EU) 2024/1689 (EU AI Act).
• If you share or publish an interpretation outside the app, you are the one placing that content into the world. You are responsible for verifying it first, for keeping or reproducing its AI-generated labelling where the law you are subject to requires disclosure, and for the consequences of its publication. We never see your interpretations and have no ability — and no obligation — to review or moderate them.

To the maximum extent permitted by law, we accept no liability for the content of any interpretation or for any loss arising from reliance on one. Nothing in this section limits rights that consumer law does not allow to be limited.

5. Difficult dreams, and when to stop

Tierce is built to keep everything: it does not soften a dream, and it does not decide that a night was better left unrecorded. Most mornings that is the point. Some mornings it is not — nightmares, grief, and dreams that arrive after something hard in waking life can be heavier to write down and heavier still to read back weeks later, next to a machine’s reading of them.

• If you live with anxiety, depression, post-traumatic stress or another mental health condition, returning to dream content daily — and to an interpretation of it — can weigh more than it lifts. Talk to your doctor or your therapist before making a practice of it. This is not a formality: it is reported that intensive attention to inner content can make some conditions harder rather than easier.
• Nobody is reading. The architecture that keeps your dreams private also means the app cannot notice that you are struggling, cannot alert anyone, and has no one behind it who could. There is no monitoring here, by design, and it must not be mistaken for care.
• Tierce is not a crisis service. If you are in danger, or thinking of harming yourself, contact your local emergency number — 112 across the European Union — or a crisis helpline in your country. Do that instead of opening the app, not after.
• You can stop at any moment, and completely. A single dream can be deleted, interpretation can be left switched off, the alarm can be turned off, and “Erase everything” in Settings removes the lot (section 11). Nothing has to be kept for the app to work, and nothing is kept anywhere else.

6. Models, licences and remote withdrawal

Interpretation runs on one of two engines: the model that ships with the operating system (governed by your agreement with the OS vendor), or an open model you choose to download — currently Qwen 3.5, released under the Apache License 2.0 by its authors and fetched from a public repository. The licence is shown before the download; nothing in these terms restricts the rights that licence gives you over the model itself.

We may update, replace or remotely withdraw a downloadable model — for quality, safety or licensing reasons. A withdrawn model is deleted from the device and the app offers its replacement; your dreams are unaffected. The app also embeds open-source components (including llama.cpp, MIT licence), each under its own licence; they are listed with their licence texts at tierce.app/licenses.

The instructions and prompts the app gives its models, like the app’s source code and design, are part of the software and remain our confidential information. No law requires their disclosure, and these terms do not grant access to them.

7. Acceptable use

You agree not to use the app or the site to break the law; not to engage in practices prohibited by Article 5 of the EU AI Act; not to attempt to bypass or interfere with the app’s safety or security features; and not to reverse engineer, decompile or disassemble the app except to the extent the law or an applicable open-source licence expressly permits. You use outputs at your own initiative and must not use them to violate the rights of others.

8. Intellectual property

The app, the site, their design, code, brand and name are ours or our licensors’, protected by copyright and trademark law. Open-source components remain under their own licences (section 6). Your content remains yours (section 3).

9. Prices, subscriptions, lifetime purchase, withdrawal

• All purchases are made through Apple’s App Store, at the price shown before you confirm. We never see your payment details. Whether the paid features are unlocked is checked through RevenueCat, our processor (see the privacy policy). Trials and promotional offers, where shown, state their conditions before you confirm.
• Subscriptions renew automatically until you cancel, which you do in your Apple account settings any time before renewal.
• A free trial, where one is offered, states its length and what it becomes before you confirm, and it converts by itself into the paid subscription at the end unless you cancel first — in your Apple account settings, at least twenty-four hours before it ends. The app also tries to remind you before that happens, but treat the reminder as a courtesy and not as a safeguard: it is a notification, so it depends on the permission you gave iOS and on the phone being able to deliver it.
• Prices can change. A change never touches a period you have already paid for: it applies from the next renewal onwards. Apple tells you in advance and, where its rules require it, asks you to agree — and if you do not, the subscription simply ends at the end of the paid period instead of renewing. The lifetime purchase is not affected by a price change at all.
• The lifetime purchase is a one-time payment unlocking the paid features for the supported life of the app on your Apple account. It is not a promise that the app will exist forever, but it is a promise that we will not convert it into a subscription.
• Refunds are handled by Apple under its terms. If you are a consumer in the EU, you have a fourteen-day right of withdrawal for digital content; by starting to use paid features immediately you consent to immediate performance, and acknowledge that the right of withdrawal is lost once delivery has begun — your statutory rights concerning defective digital content (Directive (EU) 2019/770 and national implementations, in Italy D.Lgs. 206/2005) are unaffected.

10. Warranties and liability

Nothing in these terms excludes or limits rights the law does not allow to be excluded — including your statutory guarantees as a consumer, and our liability for wilful misconduct, gross negligence, or death or personal injury caused by our negligence.

Subject to that: the app and site are provided as they are; we do not warrant that they will be uninterrupted or error-free, or that any interpretation will be accurate; and we are not liable for indirect or consequential losses, for the loss, corruption or unavailability of your content on the terms set out in section 11, or for decisions taken in reliance on machine-generated content. Where liability cannot be excluded but can be limited, our total liability is limited to the greater of the amounts you paid us in the twelve months before the event and fifty euro. That limit does not apply to consumers: against a consumer it does not operate in any way on the remedies for a lack of conformity of digital content, nor on any other right conferred by the Consumer Code, all of which remain untouched.

11. Backup, loss of data, and what cannot be recovered

Because nothing you write ever reaches us (section 3), the only copies of your dreams that exist anywhere are the one on your phone and the backup you choose to keep. Maintaining them is yours to do: leave the backup switched on, and export your archive from time to time. We cannot do it for you, and we have no copy to fall back on — that is the same architecture that keeps your dreams unreadable to us.

A forgotten backup passphrase cannot be recovered — not by us, not by Apple, not by anyone. The archive is encrypted before it leaves the phone, and the passphrase you chose is what unlocks it. If you choose not to save the key to your iCloud Keychain, that passphrase is the only thing standing between the archive and permanent unreadability; the app says so, in those words, at the moment you make that choice. A backup that can no longer be decrypted is lost for good.

“Erase everything”, and deleting the app, are immediate and irreversible. They destroy the recordings, the text, and the key that protected them. There is no undo, no grace period, and nothing on our side to restore from.

The backup is written to your own iCloud Drive, under your account and your agreement with Apple. Its availability, integrity and retention are Apple’s and not ours: we have no access to your iCloud and no control over it. The same holds for the device itself — a phone lost, broken, wiped, reset or replaced takes with it the data on it — and for any change to iOS or to Apple’s services that affects storage on your device.

Subject always to the first paragraph of section 10, and to the maximum extent permitted by law, we are not liable for the loss, corruption or unavailability of your content, however caused. This does not apply where the loss is caused by a lack of conformity of the app itself: in that case your statutory guarantees as a consumer apply in full — Directive (EU) 2019/770 and its national implementations, in Italy D.Lgs. 206/2005 — and nothing in this section limits them or the remedies they give you.

12. If you got the app from Apple’s App Store

These terms are between you and us, not Apple. Apple has no obligation to provide maintenance or support for the app, and no warranty obligation other than, where applicable, refunding the purchase price. Apple is not responsible for addressing any claim relating to the app — including product-liability claims, legal or regulatory non-conformity, consumer-protection claims, or intellectual-property claims, which are our responsibility. You represent that you are not located in a country subject to a U.S. government embargo and are not on any U.S. prohibited-parties list. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you. Your licence to the app is limited to a non-transferable licence to use it on Apple-branded devices you own or control, as the App Store rules allow.

13. Ending things

You can stop using Tierce at any time; “Erase everything” in Settings, then deleting the app, removes what was on the phone — irreversibly, as section 11 explains. We may suspend or terminate access for a serious breach of these terms. Sections that by their nature survive — 3, 4, 8, 10, 11, 14, 15 — survive.

14. Notices, transfer, and the ordinary clauses

• How we reach you, and you reach us. Tierce has no accounts, so we have no address for you and cannot write to you: anything we have to tell you is published in the app or on this site, and that is where to look for it. You reach us at legal@tierce.app, which is read by a person.
• We may transfer this agreement — if the app is sold, or if the business becomes a company — provided your rights under it are not reduced and the privacy policy’s promises travel with it unchanged. You cannot transfer yours: your licence is tied to your Apple account (section 12).
• Things outside our control. We are not responsible for a failure caused by something we could not reasonably control — an outage at Apple or at a provider, a network failure, a natural event. This does not take away your right to a refund or to end a subscription you can no longer use.
• If one clause falls, the rest stands. A provision that turns out to be void or unenforceable is severed and applies as far as the law does allow; the remaining provisions keep their full effect. Where you are a consumer, a clause that the Consumer Code makes void is void in your favour only, and the rest of the contract continues.
• Not enforcing something is not giving it up. If we are slow to exercise a right under these terms, or do not exercise it at all, we have not waived it.

15. Changes to these terms, and law

The app and these terms may change — because the app itself changes, because the law changes, because a provider or a model changes (section 6), or for reasons of security. The version in force is always the one published here, and the date at the top of this page is the date it took effect: changes take effect when they are published on this page, and continuing to use the app afterwards is acceptance of them. Where it matters, we may also say so in the app.

One exception, and it is the law’s, not ours. If a change would materially reduce what you get while you have a paid subscription running, we will say so beforehand in the app or on this site, and you may end the subscription rather than accept it. Your rights under Directive (EU) 2019/770 and its national implementations — in Italy, art. 135-decies D.Lgs. 206/2005 — apply whatever this page says.

These terms are governed by Italian law. If you are a consumer, you keep every protection of the law of your country of residence that cannot be derogated from, and disputes belong to the courts of your own place of residence or domicile — in Italy, the consumer’s forum is mandatory. You may also use any alternative-dispute-resolution body competent under your local law. Complaints reach us at legal@tierce.app first — most things can be fixed by a person reading an email.
