Terms of Use

Last updated: 22 April 2026 · Version 1.0

This is an English translation provided for convenience. The legally binding version is the Portuguese one. In case of any discrepancy between the two, the Portuguese version prevails.
During the pre-launch period, only Sections 1, 2, 3, 14, 15 and 16 apply. The remaining sections take effect once the full application opens to the public.

1. Identification

These Terms govern the use of the Z·ilom application (the "App" or "Service"), made available at zilom.pt by Link Store, Lda, a Portuguese company, tax number (NIPC) 506721523, with registered office at Av. D. Francisco de Almeida, 6, 2710-561 Sintra, Portugal, contactable at info@zilom.pt (the "Provider").

2. Purpose

The App is a decision-support software tool that estimates the maximum value to pay for urban land using the residual method, based on the market assumptions entered by the user. It includes calculation, a detailed breakdown, sensitivity analysis, viability indicators (KPIs) and PDF report generation.

Essential notice. The App does not replace an official property valuation. Valuations for banking, tax, judicial or investment-fund purposes must be carried out by a property valuer registered with the CMVM, under Portuguese Law no. 153/2015 of 14 September.

3. Acceptance and eligibility

Use of the App implies full acceptance of these Terms and of the Privacy Policy. The App is intended for adults with legal capacity to contract — private individuals, real estate agents and agencies, developers and investors. If you do not agree with these Terms, you should refrain from using the App.

4. Access models

The App is offered under the following plans:

The prices applicable at any given time are those shown at zilom.pt/precos and at checkout. All prices are shown in euros and already include VAT at the legal rate in force.

5. Discounts and special conditions

5.1. Trainee (Formando)

Participants in training sessions delivered by the Provider — present or future — benefit from a perpetual 20% discount on the public price of any subscription plan. The discount is applied automatically when the email used at registration matches the email on the trainee file, or via a coupon code provided during the training. This discount is not cumulative with the Founder price.

5.2. Lifetime Founder

Users personally invited by the Provider to the closed beta phase may benefit from a lifetime Founder price, with a 35% discount on the public price of any plan. The Founder price is maintained for as long as the subscription remains active and uninterrupted. In the event of cancellation and later reactivation, the Founder price may not be reinstated.

6. Billing and invoicing

Payments are processed by Easypay (payment services provider). Invoicing is issued through software certified by the Portuguese Tax Authority (InvoiceXpress). Invoices are available in the user's client area and sent by email. For invoicing with a company tax number, the details must be provided at the time of purchase; invoices issued without a tax number or with incorrect details may only be corrected within the legal time limits.

7. Automatic renewal and cancellation

Subscriptions renew automatically at the end of each monthly or annual period, unless the user cancels before the renewal date. Cancellation can be done at any time through the client area or by request to info@zilom.pt. After cancellation, the user keeps access to the service until the end of the period already paid for.

8. Refunds

On cancelling a subscription, the user is entitled to a refund proportional to the service not used, calculated as follows:

Pro-rata refund — "you pay for what you used"
Refund = amount paid − (number of professional reports already used × the plan's pay-per-report price)
If the value of the reports already used equals or exceeds the amount paid, the refund is zero. The refund is never a negative amount.

The refund is processed automatically through the payment provider after cancellation and may take 5 to 10 business days to appear on the original payment method. This right is in addition to applicable statutory rights, in particular the right of withdrawal in distance contracts (Portuguese Decree-Law no. 24/2014), respected on the terms set out therein.

9. Dormant account (pay-per-report)

The purchase of a one-off report automatically creates a passive user account, using only the email provided. This account lets the user re-access purchased reports by activating access via a magic link sent to their email. If the email is used again for a new purchase or subscription, previous purchases remain accessible in the history.

10. Acceptable use and limits

The user undertakes to:

Breach of these rules may lead to immediate account suspension, without right to a refund, and to civil or criminal liability under general law.

11. Data accuracy and liability

12. Intellectual property

All intellectual property rights in the App — including the "Z·ilom" brand, source code, design, content, algorithms, the structure of the residual model as implemented, and documentation — belong to the Provider or its licensors. Mere use of the App does not transfer to the user any right over these elements. Reports generated by the user belong to the user, including the right to use and share them with third parties in professional contexts.

13. Personal data

The processing of the user's personal data is carried out under the Privacy Policy, which forms an integral part of these Terms.

14. Suspension and termination of the service

The Provider may suspend, change or discontinue, in whole or in part, the App and these Terms. Material changes will be communicated to users with reasonable notice by email. In the event of definitive discontinuation of the service, users with active subscriptions will be refunded in proportion to the unused time, with no limit on reports consumed.

15. Governing law and jurisdiction

These Terms are governed by Portuguese law. The courts of the district of Lisbon have jurisdiction to settle any dispute, with express waiver of any other, without prejudice to the jurisdictions mandatorily applicable to consumers.

Consumers may also resort to an alternative consumer dispute resolution body under Portuguese Law no. 144/2015 of 8 September, consulting the list at consumidor.gov.pt.
