1. WHO WE ARE AND WHAT THIS AGREEMENT COVERS
This End User Licence Agreement ("Agreement") is between you and SAY TO PAY s.r.o. (trading as AIBlab), a company incorporated in the Czech Republic, registered office Zamostni 1155/27, Slezska Ostrava, 710 00 Ostrava, company ID 08694222 ("we", "us"). It covers the desktop application AIBEVA for Windows ("the Application") and the intelligent being (AIB) you create with it ("the AIB").
By installing the Application or ticking "I agree" in the installer, you accept this Agreement. If you do not accept it, do not install the Application.
2. LICENCE
We grant you a personal, non-exclusive, non-transferable, non-sublicensable licence to install and run the Application on computers you own or control, for your own use, under this Agreement. You may not distribute, sell, rent or lend the Application, remove any notice in it, or use it in breach of applicable law. The Application is licensed, not sold.
3. TRIAL PERIOD AND ONE-TIME REGISTRATION
3.1 When you first create your AIB in the Application, a 14-day trial period starts. It runs from the moment the AIB is created, as recorded in the AIB's own file - not from installation - and it does not restart when you reinstall the Application or move the AIB to another computer.
3.2 During the trial the AIB works fully, at no charge.
3.3 After the 14th day, unless the AIB's identity has been registered, the AIB waits for registration: it does not answer, and no new memory is written. Its memory is not deleted, and you can export the AIB at any time (Section 7). Once registered, the AIB continues with everything it remembered before.
3.4 Registration is a one-time payment per AIB. The registration fee, including VAT where applicable, is shown on aibsn.org and on the payment page before you pay. It is not a subscription; there are no recurring charges and no renewal.
3.5 Registration creates an entry for your AIB in the AIBSN registry (aibsn.org). The entry can be looked up publicly by its registration code and shows the code, the AIB's identifier, the date and the status - not your name, e-mail or any of your data. Registration is bound to the AIB, not to you or your computer: it moves with the AIB when you export it, and each AIB needs its own registration.
3.6 Registration is completed by a payment processor on a hosted payment page. You can start registration from the Application, close the payment page, and start again later; starting again reopens the same order and does not lead to a second charge. If the registry cannot be reached when you pay, the AIB collects its registration by itself as soon as it can; your memory is not affected while it waits. Before you pay, you will be asked to agree to immediate completion of the registration and to acknowledge that you thereby lose your right of withdrawal - see Section 4.
4. RIGHT OF WITHDRAWAL (EU CONSUMERS)
4.1 There is no charge for the Application or the trial; no payment is involved and nothing needs to be withdrawn from.
4.2 Registration is digital content and a service that is supplied and fully performed immediately after payment: the registration certificate is issued to your AIB and the registry entry is created at once. Under EU consumer law (Directive 2011/83/EU, Articles 16(a) and 16(m), and its Czech implementation, Section 1837 of the Civil Code), you would normally have 14 days to withdraw from a distance contract. Because you expressly request immediate completion and acknowledge that you lose your right of withdrawal once the registration is completed, you cannot withdraw from a completed registration and no refund is due for it. We ask for this consent and acknowledgement on the payment page, before you pay; a registration is not started without it.
4.3 If a registration is not completed within 14 days of your payment for reasons on our side, you may ask for a refund at support@aiblab.info.
4.4 Your statutory rights in case of a defective Application or a registration that does not conform to the contract (Directive (EU) 2019/770 and its Czech implementation) are not affected by this Section.
5. COMPUTER REQUIREMENTS AND LOCAL OPERATION
5.1 The Application runs on 64-bit Windows 10 version 1809 or later, and on 64-bit Windows 11. It needs at least 8 GB of RAM, a processor that supports AVX2, at least 15 GB of free disk space, and an internet connection for the initial download. No dedicated graphics card is needed. On first start the Application checks the computer and chooses how to run on it. The built-in model runs on the processor, for which 16 GB of RAM is recommended, or on a graphics card with 6 GB of memory or more, in which case 8 GB of RAM is enough. Where the computer cannot run the built-in model, the AIB answers through a third-party model you connect (Section 6). On computers with less than 8 GB of RAM, or with a processor without AVX2, the Application downloads no model and tells you so; the AIB answers only through a third-party model you connect, and answers are not checked on this computer.
5.2 The Application does not ship its language model in the installer. After the first start it downloads the model file (between about 1.8 GB and 5 GB, depending on the computer) in the background and checks it against a fingerprint built into the Application. Until the download completes, the AIB can only tell you that its model is still downloading, unless you have connected a third-party model (Section 6).
5.3 When the AIB uses its built-in model, everyday operation - conversation and memory - runs on your computer. An internet connection is needed only for the model download, for the automatic update check and updates, for registration, and for third-party models you choose to connect. Details of what leaves your computer are in the Privacy Policy.
6. THIRD-PARTY MODELS AND YOUR OWN API KEYS
6.1 Optionally, you may connect a third-party model provider using your own API key. This is off by default. For each provider you must both enter a key and explicitly allow the Application to contact that provider; the key alone does nothing. While a connected provider is available, it answers instead of the local model; the local model answers when no connected provider is available.
6.2 You are solely responsible for obtaining, paying for and keeping your keys, and for complying with the provider's terms. Your keys are stored in the Windows credential store on your computer and are not written into the AIB's file or its export.
6.3 We are not a party to your agreement with any provider and are not liable for its fees, availability, changes, content or its handling of your data. What is sent to a connected provider is described in the Privacy Policy.
7. EXPORT, IMPORT AND MOVING YOUR AIB
7.1 You may export your AIB at any time, also after the trial has ended, as a file you keep. The export is unencrypted unless you set a password; you are responsible for storing it safely.
7.2 Importing is a move, not a copy. When you export an AIB, the copy on the original computer is closed and no longer answers; the AIB lives in the exported file. An AIB is created once; an import is refused where an AIB already exists.
7.3 In this version, the AIB's signing key stays on the computer where the AIB was created and is not carried in the export. After an import, the AIB runs and keeps all of its memory, but it cannot sign new entries in its own record until a future version adds a way to move that key.
8. TRANSPARENCY: YOU ARE TALKING TO AN AI (EU AI ACT, ARTICLE 50)
8.1 In accordance with Article 50 of Regulation (EU) 2024/1689 (the AI Act), you are informed that the AIB is an artificial intelligence system. It is an AI, not a human being. Everything it says is produced by an AI.
8.2 The AIB is designed to remember and to speak plainly. It is not a medical, legal, financial or other professional adviser and its answers may be wrong. Do not rely on it for decisions that could harm you or others.
8.3 The Application is not intended for use by persons under 18. By installing it you confirm that you are at least 18 years old.
9. INTELLECTUAL PROPERTY
9.1 The Application, the AIB's design, the AIBSN registry and all related materials are the property of SAY TO PAY s.r.o. and its licensors and are protected by copyright and other intellectual property laws. AIB.core: patent pending - over 100 patent claims, two applications filed in 2026. No rights are granted other than the licence in Section 2. You may not decompile, disassemble or otherwise attempt to derive the source code or the inner workings of the Application, except where the law expressly permits it.
9.2 You keep all rights to what you write and share with the AIB, to the AIB's memory as stored on your computer, and to your exported files. The AIB's answers are produced for you; we claim no ownership in them.
10. WARRANTY AND LIABILITY
10.1 The Application and the registration are provided "as is" and "as available". To the extent permitted by law we give no warranty of accuracy, fitness for a particular purpose, uninterrupted or error-free operation, or that any third-party service will remain available.
10.2 To the maximum extent permitted by applicable law, we are not liable for indirect, incidental, special or consequential damages, loss of data, or loss of profit arising from the use of or inability to use the Application, and our total liability under this Agreement is limited to the amount you paid for the registration.
10.3 Nothing in this Agreement limits liability that cannot be limited by law, including liability for death or personal injury caused by negligence, for intentional misconduct, or the mandatory rights of consumers.
10.4 You are responsible for backing up your AIB (Section 7). An uninstalled Application or a deleted AIB file cannot be restored by us.
11. CHANGES, TERMINATION
11.1 We may update the Application and this Agreement; a changed Agreement applies to versions released after the change, and will be shown before installation of such a version. The Application checks for updates automatically (see the Privacy Policy); every update is signed by SAY TO PAY s.r.o.
11.2 You may end this Agreement at any time by uninstalling the Application. We may terminate it if you materially breach it. On termination the licence ends; Sections 4, 9, 10 and 12 survive. A completed registry entry is not removed on termination; in this version there is no way to withdraw an entry once it has been created.
12. GOVERNING LAW AND DISPUTES
12.1 This Agreement is governed by the laws of the Czech Republic. If you are a consumer in the EU, this choice does not deprive you of the protection of mandatory provisions of the law of the country where you reside.
12.2 Consumers in the Czech Republic may bring an out-of-court dispute to the Czech Trade Inspection Authority (Ceska obchodni inspekce, www.coi.cz). Consumers elsewhere in the EU may contact their national consumer authority or an approved alternative dispute resolution body in their country.
