Effective date: 12 October 2026

1. The agreement

These terms are an agreement between you and Conserius Inc., a Delaware corporation, Delaware file number 10775510 ("Conserius", "we", "us"), whose legal address is c/o Legalinc Corporate Services Inc., 131 Continental Dr, Suite 305, Newark, DE 19713, USA. They cover the Eyva™ app for macOS, your Eyva account, and Eyva's optional cloud service.

By installing Eyva or creating an account you accept these terms, the Acceptable Use Policy, and the Privacy Policy, which explains how personal data is handled. If you use Eyva for an organisation, you confirm you may bind it, and "you" includes it; business customers may ask for our Data Processing Addendum at privacy@conserius.com.

2. What Eyva is

An assistant that runs on your Mac. It works with your files, apps and notes, keeps its memory on your Mac, and can answer with a model that runs on your Mac.
An optional cloud service. For hard tasks, or when you ask, Eyva can send a masked request to a cloud AI model through our relay. What leaves your Mac, and its limits, are in the Privacy Policy.
An AI, not a person. Eyva is an artificial-intelligence system, and every voice it speaks with is synthetic. See the AI Disclosure.

3. Honest limits

Eyva makes mistakes. AI output can be wrong, incomplete, out of date or misleading. Check anything important before relying on it.
Eyva is not a doctor, lawyer, financial adviser or any other professional. For decisions about health, law, money, work, housing, insurance or education, ask a qualified person.
Masking is not perfect. Eyva detects most personal data before a cloud turn, not all of it.
Actions that cannot be undone are never taken without your approval in the app. You are responsible for the actions you approve.
Eyva speaks English. It writes in other languages without a certified quality claim.
System requirements: a Mac with Apple silicon (M1 or later). Eyva is built for macOS 14 and later and, as of version 1.0, has been tested on macOS 26 only.

4. Who may use Eyva

You must be at least 18. Companion chatbots may not be suitable for some minors, and Eyva is made for adults: on first launch it asks whether you are 18 or older, and if you say you are not, or tell it so later, it stops holding conversations on that Mac. One account per person. Sign-in is by a code sent to your email, so anyone who can read your email can sign in as you: keep it secure. A plan can be used on at most two of your Macs; you can remove a Mac in the app.

5. Your licence to use Eyva

5.1 We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use Eyva on Macs you own or control, while you comply with these terms.

5.2 You may not copy, sell, rent or redistribute Eyva; remove its notices; use it to build a competing product; or reverse engineer it, except where the law allows this despite this clause or an open-source licence permits it.

5.3 Eyva includes open-source software and AI models under their own licences. They are listed in the app's third-party notices, and those licences govern those parts. Where a model's licence restricts how its output may be used, that restriction applies to you too.

6. Your content

6.1 What you give Eyva and what it makes for you are yours, as far as the law allows. We claim no rights in your files, conversations or results.

6.2 What stays on your Mac is in your hands. We cannot see it, so we cannot back it up, recover it or delete it for you. Keep your own backups.

6.3 Cloud turns. To answer a cloud turn we pass the masked request to our AI provider, which processes it for us. We do not train AI models on your content, and our provider may not train its models on it.

6.4 Other people's data. If you give Eyva information about other people, you are responsible for having the right to use it that way.

7. Plans, payment, renewal and cancellation

7.1 Where plans are sold. Paid plans are sold only on our website, through Stripe, which sells them as the merchant of record and whose checkout shows the price, any tax and your currency. The app shows no prices.

7.2 Free plan. Eyva on your Mac with no time limit, plus a small daily number of cloud replies, which we may change or suspend if the cost of providing them requires it.

7.3 Paid plans are monthly subscriptions that include a monthly allowance of cloud replies. The allowance is measured by what the work costs us at the provider, so a very large request uses more of it. It resets each billing month and does not roll over. When it runs out you can keep using Eyva on your Mac until renewal. Nothing that runs on your Mac is ever metered.

7.4 Automatic renewal — please read. Your paid plan renews automatically every month, and you are charged the then-current monthly price, until you cancel. Before you buy, the checkout shows the price, the billing date, and that the plan renews until cancelled. We will email you a confirmation that includes these terms and how to cancel. We will tell you at least 30 days before a price change applies to your renewal, and you may cancel before it does.

7.5 How to cancel. You can cancel at any time, online: in the app under Settings → Account & plan → Manage subscription, which opens the payment service's own page, or by writing to support@conserius.com from your account email; we confirm the cancellation by email. Cancelling stops the next renewal; your plan stays active until the end of the period you have paid for.

7.6 Where cloud replies and paid plans are offered. As of version 1.0, cloud replies and paid plans are not offered to accounts in the EU/EEA, the UK or Türkiye; Eyva runs fully on your Mac there. The Privacy Policy, section 9, says why and what changes it.

7.7 Fair use. We may limit cloud use that is automated to extract the service, shared between people, or abusive, and we will tell you why.

8. Refunds and your legal rights

8.1 Your legal rights always apply. Nothing in these terms removes a right you have under consumer law that cannot be excluded. Where the law of the country you live in gives you a right to withdraw from a purchase, or to a refund, we honour it.

8.2 The statutory right to withdraw is in section 9. It applies to consumers in the EU/EEA, the UK and Türkiye. Consumers elsewhere do not have a right to withdraw under these terms; any right the law of their country gives them still applies.

9. Your right to withdraw (consumers in the EU/EEA, the UK and Türkiye)

If you are a consumer living in the EU/EEA, the UK or Türkiye, you have the right to withdraw from a paid plan within 14 days without giving any reason. The withdrawal period ends 14 days after the day the contract was concluded. (As of version 1.0 paid plans are not offered there — section 7.6 — but this right applies to any paid plan that a consumer living there has bought.)

How to withdraw. You must tell us clearly that you have decided to withdraw. You can:

use the "Withdraw from contract here" button in the app, under Settings → Account & plan, shown while you hold a paid plan. It asks you to confirm once and asks no reason. The app then shows the date and time our service received your withdrawal; keep that as your acknowledgement (we do not yet email it); or
write to support@conserius.com from your account email, for example using the model form below. You do not have to use it.

To meet the deadline, it is enough that you send your notice before the 14 days run out.

Effects of withdrawal. If you withdraw, you receive a pro-rata refund of the unused part of what you paid: the price minus the share of the plan's cloud allowance you had used before you told us, as recorded in your account's usage ledger (Directive 2011/83/EU Art. 14(3), and the UK and Turkish rules to the same effect). The refund is paid without undue delay and at the latest within 14 days of the day we were informed, by Stripe as the merchant of record, to the payment method you used, at no cost to you. The amount is computed by software from your account's records, never by hand or by an AI model, and the remaining allowance ends when the refund is issued.

Model withdrawal form — To Conserius Inc., c/o Legalinc Corporate Services Inc., 131 Continental Dr, Suite 305, Newark, DE 19713, USA, support@conserius.com: I hereby give notice that I withdraw from my contract for the following service: Eyva (the plan named on my receipt), ordered on (date). Name: … Account email: … Date: …

10. Updates and availability

This build does not update itself. When updates exist, Eyva will tell you and never install over itself without you. If a change reduces what your paid plan includes, we tell you in advance and you may cancel. If we change what data leaves your Mac, we tell you in the app before it applies. Cloud replies depend on third-party providers and may be unavailable; Eyva on your Mac keeps working without them.

11. Ending

You can stop using Eyva and delete your account at any time: in the app under Settings → Account & plan → Delete account, or by writing to support@conserius.com from your account email. A subscription that still renews must be cancelled first (section 7.5). We may suspend or end your account if you seriously or repeatedly break these terms, if the law requires it, or if our provider stops serving your region; where we can, we warn you first and say why. When an account ends, cloud access stops; what is on your Mac stays there. Sections 6, 8, 9 and 12–15 survive.

12. Disclaimers

To the extent the law allows, Eyva is provided "as is" and "as available", without warranties of merchantability, fitness for a particular purpose or non-infringement, and without a promise that it will be uninterrupted or error-free, or that masking will detect every item of personal data. Consumers keep the statutory guarantees of their country.

13. Limitation of liability

To the extent the law allows: (a) we are not liable for indirect, incidental, special, consequential or punitive damages, or for loss of data, profits or goodwill; and (b) our total liability for all claims about Eyva is limited to the fees you paid us in the 12 months before the claim, or USD 100 if you paid nothing. There is no limit on our liability for death or personal injury caused by our negligence, for fraud, or for any liability that the law does not allow us to limit.

14. Indemnity

If you use Eyva for a business, you will defend and compensate us against third-party claims arising from your content or your breach of these terms. This does not apply to consumers.

15. Governing law and disputes

These terms are governed by the law of the State of Delaware, USA, and disputes go to the courts of Delaware. If you are a consumer, you keep the protection of the mandatory laws of the country you live in, and you may bring a claim in the courts of that country (for consumers in the EU, Rome I Regulation Art. 6 and Brussels I Regulation Art. 18). There is no arbitration clause and no class-action waiver in these terms.

16. General

These terms, the Acceptable Use Policy, the Privacy Policy and the pricing shown at checkout are the whole agreement. If a clause is invalid, the rest stays in force. We may assign these terms in a merger or sale; you may not assign them without our consent. We give at least 30 days' notice of material changes in the app or by email; if you do not accept them, you can cancel. Export-control and sanctions laws apply to your use of Eyva.
