Terms of Service

Publisher

Tacita is published by an independent EU sole trader. Legal contact: [email protected]. Support: [email protected]. Full trader identification is on the Imprint page.

Acceptance

By installing or using Tacita you accept these terms. If you do not accept them, uninstall the app.

License to use

You are granted a personal, non-exclusive, non-transferable license to install and use Tacita on devices you own or control, for personal use, subject to these terms. You may not redistribute the app or its compiled components, reverse-engineer them, or extract the model binaries for redistribution.

On-device AI

The language model runs locally on your device. The developer does not see, store, transmit, or moderate anything you write or anything the model produces. There is no central server. There is no remote moderation. You are responsible for what you generate and how you use it.

AI content disclaimer

Output from the language model can be inaccurate, biased, offensive, or unsafe. The model has no live access to the internet, no way to verify its claims, and no understanding of the real consequences of its words. Treat its output as a draft, not as advice.

Tacita is not a substitute for professional advice — medical, legal, financial, psychological, or otherwise. In emergencies, call the appropriate local services (in EU: 112).

A fuller version of this disclaimer is available on the AI Disclaimer page.

Imported character packs (.kaichar)

You may import character packs that other people created and shared. These packs contain personas, system prompts, and rules written by third parties. Tacita does not host, distribute, or moderate them. You import them at your own risk and remain responsible for the content they cause the model to generate. The app displays a preview before every import — review it carefully.

Models from third-party hosts

You may install language model files (.gguf) from public hosts such as Hugging Face. Each model file is governed by its own license — most notably, models from the Gemma family are subject to Google’s Gemma Terms of Use. It is your responsibility to read and comply with the license of each model you choose to install.

In-app purchase: Tacita Pro

Tacita is a one-time purchase. There are no subscriptions, no recurring bills, and no consumable tokens. Three lifetime products are sold via the App Store / Google Play in your local currency, each including any applicable taxes:

• “Tacita Pro” — unlocks every Pro feature on the Upgrade screen (no ads, web search, vision, full sampling control, long replies, persistent memory).
• “Tacita Pro+Bridge” — Tacita Pro plus the Bridge add-on, which lets the app connect to Tacita Desktop over your local network for image generation in chat, persona avatars, and multi-device sync. Sold as a single bundled purchase.
• “Tacita Pro → Pro+Bridge upgrade” — surfaces only when you already own Tacita Pro and are looking at a Bridge feature. Adds the Bridge entitlement on top of your existing Pro purchase, so you pay the delta instead of the full Pro+Bridge price.

Every purchase is tied to your store account and can be restored on any device using the same account, free of charge. Refunds are governed by Apple’s and Google’s standard refund policies; we do not process refunds directly.

Acceptable use

You agree not to use Tacita to generate content that is illegal in your jurisdiction, that targets a real identifiable person without consent, that depicts minors in sexual contexts, that incites violence or terrorism, or that infringes intellectual property.

We cannot enforce this — inference is local — but doing any of it is your responsibility, not the developer’s. Misuse may also violate the licenses of the underlying language models.

Forgotten passwords

There is no password recovery. Conversations and settings inside a vault you cannot unlock are mathematically unreachable. We have nothing to send you, no link to reset. This is the cost of the privacy guarantee.

No warranty

The app is provided “as-is”, without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement. To the maximum extent permitted by law, the developer disclaims all such warranties.

Limitation of liability

To the maximum extent permitted by law, the developer is not liable for any direct, indirect, incidental, consequential, special, or exemplary damages arising from your use of the app, including but not limited to data loss, lost profits, or distress caused by model output.

Nothing in these terms limits liability that cannot lawfully be excluded — notably, gross negligence, wilful misconduct, or harm to life and physical integrity remain governed by mandatory law.

Termination

You may terminate this agreement by uninstalling the app. Doing so removes all on-device data, including encrypted vaults — same caveats as the deletion section of the Privacy Policy.

Governing law and jurisdiction

These terms are governed by the laws of Belgium, excluding its conflict-of-laws rules. Any dispute that cannot be resolved amicably is subject to the exclusive jurisdiction of the courts of Brussels, Belgium.

EU consumer carve-out

If you are a consumer habitually resident in the European Union, the choice of Belgian law above does not deprive you of the protection afforded by the mandatory consumer-protection rules of your country of residence (Article 6 of Regulation (EC) No 593/2008, “Rome I”). You retain the right to bring proceedings in the courts of your country of residence.

Changes

A material change to these terms means a new app version. There is no remote update of these terms. By updating the app you accept the version of the terms shipped with that release.
