Version 0.1 — 8 September 2026


DeeZen End User Licence Agreement ("Agreement")

This Agreement is between you and ZenCognitics Pty Ltd, an Australian company ("ZenCognitics", "we", "us"). It governs your use of the DeeZen desktop software and related services ("DeeZen" or the "Software").

By clicking "I Agree", installing, or using DeeZen, you accept this Agreement. If you do not agree, do not install or use DeeZen, and uninstall it.

We wrote this in plain English because we think you should be able to read the terms you accept. Where the law gives you rights that cannot be taken away (section 14), this Agreement does not take them away, and nothing below should be read as trying to.

1. What DeeZen is

DeeZen is an AI assistant that runs on your own computer:

DeeZen is software, not a human adviser. It is a tool you control.

2. Your licence

We give you a personal, non-exclusive, non-transferable, revocable licence to install and use DeeZen:

You may not copy, sell, rent, sublicense, or redistribute the Software; reverse-engineer it except where the law allows it regardless; remove notices; or use it to build a competing hosted service. The licence covers our code. Third-party models and engines inside DeeZen are licensed by their own owners under their own terms (section 12), and open-source components under their own licences (section 12.3).

3. Paid features, billing and cancellation

  1. DeeZen has a free tier. The free tier provides real, usable functionality on your device. We may change what is in the free tier, but if we make a change that removes core functionality you were told was free, we will say so clearly in advance.
  2. Paid features (such as the monthly subscription and media credit packs) are sold to you by Paddle.com Market Limited ("Paddle"), which acts as merchant of record: Paddle is the seller of the transaction, charges you, collects applicable taxes (VAT/GST/sales tax), and issues refunds under its processes. Your purchase is also subject to Paddle's Buyer Terms.
  3. Subscriptions renew automatically at the then-current price until you cancel. The price and billing period are shown before you pay. You can cancel at any time through the link in your purchase email or by contacting Paddle support — cancellation stops future renewals; it is as easy to cancel as it was to sign up.
  4. Credit packs are prepaid, are priced in US dollars, do not expire, and are consumed only when you actually use the metered feature. Credits are not cash, are not refundable except where the law requires, and cannot be transferred for value.
  5. If we change the subscription price, we will give you at least 30 days' notice before the change applies to you, and you may cancel before it takes effect.
  6. Where you have a legal right to a refund or withdrawal (section 14), that right is not affected by this section.

4. Your privacy, in one paragraph

DeeZen is built local-first. Your conversations, memories, files, scheduled tasks, and API keys are stored on your device, not on our servers. We do not run an account system for the core product and we do not receive your content. The personal information we handle is limited to: what Paddle collects to process your purchase (Paddle is the controller of that), and anything you choose to send us directly (for example a support email). Our full privacy notice is at deezen.ai/privacy.

Our privacy promise, stated exactly: whatever DeeZen processes on your device is private. Nothing more is promised. When a task needs more than your device can do, DeeZen uses an off-device route that is described honestly in the product — your own provider account on your key (their terms apply to that traffic), or a Dee server we run (translation, the native-language shared brain, and any future shared services). Those off-device hops are described as such in the product, are opt-in or clearly labelled where they occur, and are never claimed to be private. Local means private; anything else means the terms of the server it reaches.

5. Your own API keys ("BYOK")

  1. If you choose to use cloud AI tiers, you provide your own API key from your chosen provider. Your key is stored on your device. DeeZen sends it only from your device to that provider, only to make requests you initiate.
  2. Your relationship with that provider — including its prices, its terms, its acceptable-use rules, and its handling of your data — is between you and that provider. Usage on your key is metered and billed by the provider to you. We are not the seller, reseller, or biller of that usage, and we are not responsible for your provider bills.
  3. DeeZen shows you a cost ceiling (the Saver/Balanced/Best dial) and estimates to help you control spend, but estimates are estimates: the provider's own metering is what you are billed on.
  4. You are responsible for keeping your keys safe and for revoking a key you believe is compromised.

6. AI output — the honest limits

  1. AI can be wrong. Output may be inaccurate, incomplete, out of date, or inappropriate for your situation. Check important output before relying on it.
  2. Not professional advice. DeeZen is not a doctor, lawyer, accountant, financial adviser, or any other licensed professional, and its output is not professional advice. For medical, legal, tax, financial, or similarly significant matters, consult a qualified professional. DeeZen is designed to recognise such topics and tell you to do exactly that — but the responsibility to get professional advice remains yours.
  3. You are interacting with an AI. DeeZen is an artificial intelligence system, and content it or its media features produce is AI-generated or AI-assisted. Where the law requires AI-generated content to be labelled, do not remove those labels.
  4. Safety features are best-effort, not a guarantee. DeeZen includes automated safety guardrails. They reduce risk; they cannot catch everything, and their presence does not make an unsafe use safe (section 11).
  5. Ownership of output. As between you and us, and to the extent the law allows, you own the output DeeZen generates for you, and you are responsible for how you use it. Note that: (a) similar output may be generated for others; (b) copyright in AI-generated material is an evolving area of law in many countries; and (c) if you used BYOK cloud tiers, your provider's terms also speak to output.

7. Media generation and credits

Media features (image, video, audio) may use third-party generation services chosen in the product, or a local draft lane on your own hardware. Metered media consumes credits or uses your BYOK key as shown in the product before you generate. Generated media must comply with section 11. You are responsible for having the rights to any image, audio, or likeness you supply as input.

Credits are a prepaid balance, not a subscription. They never expire. A credit is a US$0.05 unit (100 credits = the US$5 pack); the number of credits a render costs is shown before you generate and may change as third-party provider costs change. A price change does not reduce your balance or make it expire. Credits are not redeemable for cash except where required by law; refunds are handled under the Australian Consumer Law and the purchase terms shown at checkout.

8. Household mesh and remote features

  1. The household mesh lets computers you own or administer share capability. You must only add, approve, delegate jobs to, diagnose, or run maintenance on a device you own or are explicitly authorised to administer. Doing any of that to someone else's computer without authority may be a crime where you live, and it is a breach of this Agreement.
  2. Remote jobs and maintenance actions are logged and require the owner-side approvals built into the product, but you are responsible for what you ask another machine to do.

9. Voice features

Voice features process speech on your device by default. If you use DeeZen to record or transcribe any conversation, call, or meeting, you are responsible for complying with the recording-consent laws that apply (some places require everyone on the call to agree).

10. Age

You must be at least 16 to use DeeZen. If you are under 18, you may use it only with a parent or guardian's agreement and supervision.

11. Acceptable use

You must not use DeeZen to:

  1. break any law, or plan, encourage, or assist anyone to break any law;
  2. harm, exploit, or endanger any person — including creating sexual content involving minors, non-consensual intimate imagery, or stalking or harassment material;
  3. develop weapons, malicious code, fraud, or deception;
  4. infringe intellectual property, privacy, or publicity rights — including uploading input you have no right to use;
  5. mislead others about the AI-generated nature of content where disclosure is required by law;
  6. probe, attack, or interfere with the Software, its licence checks, or third-party services; or
  7. use another person's computer, keys, or accounts without authority (section 8).

We may suspend or terminate access for breach of this section, and where the law requires we will report unlawful material to the proper authorities.

12. Third-party components

  1. On-device models and engines. DeeZen includes AI models and inference software made by others (currently including Google's Gemma, Meta's Llama, Alibaba's Qwen, and llama.cpp). These are governed by their own licences and acceptable-use policies, which are presented to you in the installer and ship in the NOTICE file. Those terms flow down to your use of those components — including their prohibited-use policies — and where those terms conflict with this Agreement for those components, those terms win for those components.
  2. Cloud providers (BYOK). Their terms govern their services (section 5).
  3. Open-source software. DeeZen contains open-source components listed with their licences in the NOTICE bundle installed with the Software. Nothing in this Agreement limits your rights under those licences.
  4. Paddle. Purchases are also subject to Paddle's buyer terms (section 3.2).

13. Warranties we give everyone

We warrant that: we have the right to license the Software to you; paid features will materially do what we describe at deezen.ai and in the product; and we will provide the Software with reasonable care and skill. If a paid feature materially fails this and you tell us, we will fix it, re-supply it, or refund the affected fees — without limiting anything in section 14.

14. Your consumer rights (this section wins over everything else)

Australia. Our goods and services come with guarantees that cannot be excluded under the Australian Consumer Law. For major failure with a service, you are entitled to cancel your service contract with us and get a refund for the unused portion, or to compensation for its reduced value. You are also entitled to choose a refund or replacement for major failure with goods. If a failure with goods or a service is not major, you are entitled to have the failure corrected in a reasonable time; if we do not, you can get a refund. The benefits of this Agreement are in addition to your rights under the Australian Consumer Law.

New Zealand. Nothing in this Agreement limits rights you have under the Consumer Guarantees Act 1993 or the Fair Trading Act 1986 that cannot lawfully be limited.

United Kingdom. Digital content must be as described, fit for purpose, and of satisfactory quality under the Consumer Rights Act 2015. Nothing in this Agreement affects your statutory rights, including repair, replacement, price reduction, or refund rights for non-conforming digital content, or your 14-day cancellation right for distance contracts, subject to the rule that for digital content supplied immediately with your express consent and acknowledgement, the cancellation right is lost once supply begins.

European Union / EEA. You benefit from mandatory consumer protections of your country of residence, including the legal guarantee of conformity for digital content (Directive (EU) 2019/770) and — unless you consented to immediate supply and acknowledged losing it — the 14-day withdrawal right (Directive 2011/83/EU). Nothing in this Agreement limits those rights.

Everywhere else. You keep every right you have that cannot lawfully be excluded, restricted, or modified. To the extent a right can be limited, we limit our liability to re-supplying the services or paying the cost of re-supply, as the law permits.

15. The as-is part (with section 14 always winning)

Except for section 13 and the non-excludable rights in section 14, the Software is provided "as is" and "as available". To the maximum extent the law allows, we disclaim all other warranties, express or implied — including merchantability, fitness for a particular purpose, and non-infringement — and we do not warrant that the Software will be uninterrupted, error-free, or that AI output will be accurate (section 6).

16. Liability

  1. Nothing in this Agreement excludes or limits our liability for: death or personal injury caused by our negligence; fraud or fraudulent misrepresentation; or any liability that cannot lawfully be excluded or limited (including under section 14).
  2. Subject to 16.1, we are not liable for indirect, incidental, special, or consequential loss, or for loss of profits, revenue, data, or goodwill, arising from the Software or this Agreement.
  3. Subject to 16.1 and 16.2, our total aggregate liability arising out of or relating to the Software or this Agreement is capped at the greater of: (a) the amounts you paid for DeeZen in the 12 months before the event giving rise to the claim; and (b) AUD $100.
  4. AI output, and what you do with it, is covered by section 6 — including that you are responsible for checking important output and for your use of BYOK provider spend.

17. Changes to DeeZen or to this Agreement

We may update the Software (it is designed to be honest about what changes). We may change this Agreement by posting the new version at deezen.ai/terms and, for material changes, giving at least 30 days' notice in the product or by email. If a change materially disadvantages you as a paying user, you may cancel before it takes effect and get a pro-rata refund of prepaid subscription fees. Continuing to use DeeZen after a change takes effect means you accept it.

18. Term and termination

This Agreement lasts until terminated. You may terminate it at any time by uninstalling DeeZen and cancelling any subscription. We may terminate or suspend your licence if you materially breach this Agreement and do not fix it within 14 days of notice, or immediately for breaches of section 11. On termination: your licence ends; sections 6, 11, 14–16, 20 and 21 survive; and your local data stays on your device — deleting it is up to you.

19. Export and sanctions

You must comply with export-control and sanctions laws. You confirm you are not located in, ordinarily resident in, or a person listed under, an embargoed country or restricted-party list (including those of Australia, the US, the EU, and the UN), and you will not allow DeeZen to be used in violation of those laws.

20. Governing law and disputes

This Agreement is governed by the laws of Western Australia, excluding conflict-of-laws rules. The courts of Western Australia have non-exclusive jurisdiction. However, if you are a consumer, this does not deprive you of the protection of the mandatory laws of the country where you live, and you may bring claims in the courts of your own country where the law gives you that right. The UN Convention on Contracts for the International Sale of Goods does not apply.

21. General

If any part of this Agreement is held invalid or unenforceable, the rest continues. Our failure to enforce a provision is not a waiver. This Agreement, the documents it references (including the privacy notice and the third-party notices), and your Paddle purchase terms are the entire agreement between us about DeeZen. You may not assign this Agreement without our consent; we may assign it to an affiliate or in connection with a sale of the business, with notice where the law requires.
