Terms governing use of the MEFYS cloud service operated by ROOT4U s.r.o.

1. Introduction and provider

The MEFYS service (the “service”) is operated by ROOT4U s.r.o., Company ID (IČO) 07669470, VAT ID CZ07669470, registered office Palackého 650, 512 51 Lomnice nad Popelkou, Czech Republic, recorded in the Commercial Register kept by the Regional Court in Hradec Králové, Section C, File 42802, e-mail [email protected], tel. +420 727 970 563 (the “provider”).

These Terms govern the rights and obligations between the provider and the user and form an integral part of the contract. The relationship is governed by the laws of the Czech Republic, in particular Act No. 89/2012 Coll., the Civil Code.

2. Definitions

• User — a natural or legal person who creates an account.
• Consumer — a user who is a natural person concluding the contract outside their business activity.
• Plan — the chosen service tier (Free, Start, Standard, Business).
• Subscription — paid use of the service on a monthly or yearly basis.
• Account — the user’s workspace within the service.

3. Contract, registration and account

• The contract is formed upon completing registration at app.mefys.cz/signup and its confirmation. The user provides true and current information.
• The user is responsible for the security of login credentials and for activity on the account.
• The account is non-transferable without the provider’s consent.

4. Plans, prices and payment

• Current plans and prices are listed at mefys.cz. For businesses, prices are shown excluding VAT; a consumer is always shown the final price including VAT before binding confirmation of the order.
• The subscription may be paid monthly or yearly; yearly payment is discounted by 10%. The currency is the Czech koruna (CZK).
• Payment is cashless (payment card or bank transfer).
• A paid subscription renews automatically for another period of the same length at the then-current price until the user cancels it (see clause 7).
• The provider issues and makes available a tax document electronically.
• In the event of late payment, the provider may suspend access until the amount due is paid.

5. Free trial

A new account has a 14-day free trial with full functionality and no payment card required. Afterwards the user chooses a paid plan or continues on the free Free plan within its limits.

6. Consumer right of withdrawal

If the user is a consumer, they have the right to withdraw from the contract within 14 days without giving a reason. The period runs from the day the contract is concluded. A clear notice sent to [email protected] is sufficient.

Notice: The consumer expressly requests that provision of the service (digital content) begin during the withdrawal period. In accordance with Section 1837 of the Civil Code, the consumer acknowledges that once the service has been fully provided, the right of withdrawal ceases. If the service was provided only in part at the time of withdrawal, the consumer pays a proportionate part of the price.

7. Term and termination

• The contract is concluded for an indefinite period; the user may terminate it at any time by cancelling the subscription or account, or by notice to [email protected].
• Automatic renewal can be turned off at any time before the end of the current period; the service then runs until the end of the paid period.
• Upon termination the user may export their data; after a reasonable period the data may be deleted.
• The provider may restrict or close the account for a material breach of these Terms or for non-payment.

8. User rights and obligations

The user agrees not to misuse the service, not to disrupt its operation or security, and not to store unlawful content. The user is responsible for the data entered into the service and its compliance with the law.

Access keys and AI connection (MCP): If the user creates access keys (API / MCP) or connects the service to a third-party AI assistant, the user is responsible for their security, for the scope of granted permissions, and for the conduct and outputs of such an assistant. The provider is not responsible for the operation, availability or outputs of third-party AI tools; AI control is an optional add-on and the service can be used fully without it.

AI document extraction: The AI extraction feature passes the content of an uploaded document to an AI service provider (Anthropic, PBC) acting as the provider's processor, solely for the purpose of automated data extraction. The output is always only a draft of a document, whose accuracy the user is obliged to review before approval; the provider is not responsible for the accuracy of automatically extracted data prior to its approval by the user. The number of extracted documents is governed by the selected plan; beyond the plan, additional extractions can be purchased as a paid pack (non-expiring credit) at the prices shown in the app.

9. Availability and support

The provider makes reasonable efforts to ensure continuous and error-free operation but does not provide an express availability guarantee. Operation may be temporarily limited for maintenance or for reasons beyond the provider’s control. Support is provided by e-mail at [email protected].

10. Complaints and defect rights

If the service shows defects, the user may file a complaint by e-mail to [email protected] describing the issue. The provider handles complaints without undue delay; for a consumer, no later than 30 days unless agreed otherwise. Rights from defective performance are governed by the Civil Code.

11. Liability and its limitation

The service is provided “as is”. The provider is not liable for indirect damages or lost profit. Any compensation is limited to the subscription paid by the user over the last 12 months, to the extent permitted by law. The limitation does not apply where the law does not allow it (in particular for personal injury or harm caused intentionally or by gross negligence).

12. Personal data protection

Processing of personal data is governed by the Privacy Policy, and the use of cookies by the Cookie Policy.

13. Out-of-court dispute resolution

For out-of-court resolution of a consumer dispute, the competent body is the Czech Trade Inspection Authority (Česká obchodní inspekce), Štěpánská 567/15, 120 00 Prague 2, web coi.cz, platform adr.coi.cz. A consumer may also use the EU online dispute resolution platform at ec.europa.eu/consumers/odr.

14. Changes to the Terms

The provider may amend these Terms, in particular in response to developments in the service or the law. The provider notifies users of material changes in advance (by e-mail or in the service). If the user disagrees, they may terminate the contract; by continuing to use the service the user accepts the amended version.

15. Final provisions

The contract is governed by the laws of the Czech Republic. If any provision is invalid or ineffective, it does not affect the validity of the remaining provisions. These Terms take effect on 1 July 2026.
