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 8).

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.

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. 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.

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.

6. 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.

7. 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. Your content remains yours (section 3).

8. 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.
• 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.

9. 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 loss of data you chose not to back up, 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.

10. 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.

11. Ending things

You can stop using Tierce at any time; “Erase everything” in Settings, then deleting the app, removes what was on the phone. We may suspend or terminate access for a serious breach of these terms. Sections that by their nature survive — 3, 4, 7, 9, 12 — survive.

12. Changes and law

The app and these terms may change; the models especially may change (section 5). Material changes to these terms are announced in the app or on this site at least thirty days before they take effect where practicable; continuing to use the app after that is acceptance. 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.
