AI in Treasynx
Last updated 17 October 2026 · bmvp.ai Ltd
The short version
AI in Treasynx is optional and stays off until you set it up. You choose how it works: an AI provider you pick, with your own key; a small model you install on your phone; Treasynx AI, our own small model, which runs on your phone for four planning jobs and is downloaded only if you choose it; or no AI at all, because the planner works without it. No AI request passes through us. AI output is labelled, it can be wrong, and nothing in your day changes until you accept it.
Ways to use Treasynx
No AI at all
The planner works without any AI. Your first plan, your templates and the timing of your day are worked out by the app's own code on your phone. On a fresh install no AI provider is set up, and no AI feature makes a network request until you set one up yourself.
Your own provider, with your own key
You can connect one of fifteen providers: OpenAI (or any OpenAI-compatible service), Anthropic, Google Gemini, Grok (xAI), Groq, DeepSeek, Mistral, OpenRouter, Together, Fireworks, Cerebras, Perplexity and DeepInfra, or Ollama and LM Studio running on your own computer. You create the key with the provider, under your own account, and the provider bills you directly. We take no cut.
Your key is stored on your phone, encrypted with a key held in the phone's secure hardware. It is shown masked, like a password, and is sent only to the provider it belongs to. We never receive it.
A model on your phone
You can also install a small language model on the phone and use the AI features with no key, no account and no network. You get the model file from its publisher (for example Google's Gemma models, from Hugging Face), accept the publisher's licence, and import the file into the app. We do not supply or host the model. With this option, nothing about your schedule leaves the phone.
Treasynx AI, our own small model
An optional model made by us that runs on your phone, offline, for four planning jobs. Everything else uses one of the choices above. See Treasynx AI below.
What goes to an AI provider, and when
- Only when you use an AI feature. Nothing is sent to a provider in the background, and nothing at all if you use no AI, the model on your phone or Treasynx AI.
- What is sent: the request for that feature. It may include your schedule, task titles, notes, a summary of patterns the app has learned, and any text you type into an AI box.
- Hide task titles and notes. With this setting on in AI settings, block titles are replaced by their type (such as "Study block"), and notes and earlier AI answers are left out. Text you type into an AI box yourself is still sent as you typed it.
- Never sent to an AI: money amounts and business data. Health diary entries are sent only if you switch on AI sharing in Health.
- Directly to the provider. Requests go from your phone straight to the provider you chose. They do not pass through us, and we never see your prompts or the answers.
The provider handles your request under its own terms and privacy policy, not ours, so it is worth reading the ones that apply to you. You are responsible for any costs and for following the provider's terms. Some providers are outside the UK; for example, DeepSeek processes requests in China. See the privacy policy for the full list of where data can go.
Labels and transparency
In the spirit of Article 50 of the EU AI Act, Treasynx tells you when content comes from an AI:
- Tasks written by an AI carry a visible AI label in the app, so you can tell them from your own.
- Exports and shared files mark AI-written items with [AI] and a note that AI can be wrong.
- The marking is also saved with the data itself, including which kind of provider and model wrote it, so it stays with the item in backups and exports.
- The chat assistant says that it runs on the AI provider you set up.
- Text the app did not get from you just now, such as calendar events, notes, imported files or earlier AI answers, is given to the AI as information to read, never as instructions to follow.
- You can report any AI response in the app. The report stays on your phone unless you choose to email it to us, and you decide whether the AI's response goes with it.
AI can be wrong
AI output can be inaccurate, or entirely made up. Check anything important before you rely on it. Nothing an AI writes in Treasynx is medical, financial or legal advice.
The AI only suggests. When it proposes adding, moving or removing a block, each suggestion has its own button, and nothing changes until you press it. The AI has no way to set alarms, change settings, spend money or reach anything outside the app.
Treasynx AI: our own small model, optional
From version 1.2.1, Treasynx AI is available in the app as an option. It is a small AI model made by bmvp.ai Ltd, based on Qwen3-0.6B (Apache-2.0 licence). It is downloaded only if you choose it: in AI settings, choose Treasynx AI, read the first-use notice, then tap Download. The file is about 640 MB, so Wi-Fi is recommended. Nothing is downloaded before you tap.
It runs on your phone
Treasynx AI runs on your phone's processor and works offline. What you type into it is processed on the phone and is not sent to us or anyone else, and it is not used to train it. Answers can be slow on some phones.
What it does
- Help answers: how to do something in Treasynx, from the app's own help, with a link to the help topic it used.
- Quick capture: turns a note into a task you check before it is saved.
- Duration estimates: suggests how long a task should take, from your own history first.
- Weekly review: a short summary made only from your own numbers.
Everything else uses your own AI provider, which you choose under "Other AI features use" in AI settings, or the app's own planner. Treasynx AI tells you when a request is outside its four jobs.
It can be wrong
It is a small model and it can be wrong. The app checks each answer, and if an answer fails the checks, the app's own planner or help steps in and says so. Check what it suggests before you use it. It is not medical, financial or legal advice, and it does not answer money, health, legal or food-safety questions.
Signed and checked before it is installed
Before anything is installed, the app fetches a small list of versions from treasynx.com and checks two digital signatures on it, Ed25519 and ML-DSA-65 (a post-quantum signature standard, FIPS 204), against keys built into the app. Both must be valid. The app then checks the model file's exact size and SHA-256 fingerprint against that list before the file is used. A file that fails any check is deleted.
Where the file comes from
The model is delivered from models.treasynx.com, which is served by Bunny.net (BunnyWay d.o.o., a company in Slovenia, in the EU). The files are stored in the UK, and we have switched off Bunny.net's request logs. Like any download, Bunny.net receives your phone's IP address so that it can deliver the file; nothing else about you is sent. See the privacy policy.
Versions and training
This is version 0.1. It was trained on synthetic examples generated from the app itself and on examples we wrote, with no personal data. The model card shows how it was tested, where it does better and worse than the app's own planner, and which tasks are held back. Each version is listed in the changelog. New versions should improve over time; that is an aim, not a promise.
You can remove the model at any time in AI settings → Treasynx AI → Remove.
Your data and your choices
- Help improve Treasynx has two separate boxes, and both start unticked. The first allows a pseudonymous weekly summary of how the app is used. The second, which needs the first, also allows those numbers to be used to train and test Treasynx AI. Sending is not switched on in the current version, so nothing leaves your phone for this feature yet. See Help improve Treasynx.
- Usage statistics are off unless you switch them on, and declining changes nothing in the app.
- Age: Treasynx is for adults aged 18 and over.
