Terms of Use

Version in force as of 2 November 2026 (Garentiz 3.14.23).

These terms govern the use of the Garentiz platform, on the website www.garentiz.com and in the Garentiz mobile applications for iOS and Android, published by Nayaro SRL (BE 0647.588.826, Chemin de la Cure d'Air 16, 7000 Mons, support@garentiz.com), hereinafter “Garentiz” or “we”. They apply to any person who creates an account or uses the platform: landlord, partner co-owner, delegate, tenant, tradesperson, rental applicant or referral partner. The Terms of Sale supplement these terms for the purchase of licences.

1. Purpose of the platform

Garentiz is a rental management tool intended for private landlords established in Belgium. In particular, it enables users to keep track of properties and their units, leases, rent and payments (including by importing CODA, CSV or Excel bank statements), due dates, documents, tenant requests (including through a property's QR code), check-in and check-out inventory reports, rent indexation, the end of a lease and the rental deposit, insurance claims, tradesperson jobs and rounds, letting (listing, viewings, applications), expenses, loans and a budget, a bank file and reports, and to keep a time-stamped register of actions. The features available depend on the licence level of each property, as described in the Terms of Sale. Regulatory calculations (indexation, notice and end of lease, rental deposit) follow the rules of the Region where the property is located: Walloon decree of 15 March 2018, Brussels Housing Code, Flemish Housing Lease Decree of 9 November 2018. The rule applied and its version are written to the register with each calculation.

Excluded lettings. Garentiz is designed for residential leases (main residence, short-term, student) and the garage, commercial or other leases it offers. It is not suitable for, and must not be used for, tourist lettings or short-term furnished lettings (from a few nights to 90 days, tourist accommodation subject to its own regional rules) nor, for the time being, for tied accommodation, precarious occupancy, subletting, a sliding lease from a social rental agency (AIS/SVK) or renting a room in the owner's home: Garentiz's rules and documents are not suited to them.

Garentiz is a tool, not advice. The calculations (for example of indexation or final statements), reminders, document templates, explanations and proposals of the assistant are provided as an aid. They do not constitute legal, tax or accounting advice. Each user remains responsible for their decisions, for the documents they use and for compliance with applicable legislation, in particular regional regulations on residential leases. If in doubt, consult a professional.

2. User account and login

• You must provide accurate information and an e-mail address that you check. Garentiz is intended for adults.
• You can log in with your e-mail address and a password, with a single-use login link sent by e-mail (valid for 15 minutes), or with your Google or Apple account. With Google or Apple, we receive from that service your e-mail address, your name and an identifier specific to the service; Apple may offer to hide your address, in which case we receive a relay address provided by Apple. An account created in this way has no password.
• You are responsible for keeping your login credentials and access to your account confidential. We recommend enabling two-factor authentication (code from an authenticator app, with backup codes); once enabled, it is required at every login with a password or a link. Logging in with Google or Apple relies on the security of your Google or Apple account: protect it as well.
• In the mobile application, each connected phone receives its own device token. You can see your connected devices in “Settings” and disconnect any of them at any time; logging out of the application also removes the device.
• An account is personal. To entrust the management of a property to a third party, use delegation; to share ownership of the account with a co-owner, invite a partner co-owner. Each action is recorded in the register in the name of its author. If Garentiz support enters your account to assist you, you are notified by e-mail and every action taken during the assistance is recorded in the register with that mention.
• Notify us without delay at support@garentiz.com if you suspect unauthorised access.

3. Roles and responsibilities

• Landlord: enters their properties, leases and the data of their tenants, applicants, guarantors, tradespeople and other data subjects. For this data, the landlord is the controller within the meaning of the GDPR; Garentiz acts as their processor, under the Data Processing Agreement.
• Partner co-owner: a co-owner invited by the landlord, with the same rights on the account as the landlord.
• Delegate (for example a property manager or an accountant): acts on behalf of the landlord, within the limits of the delegation granted.
• Tenant: has access to the information on their lease made available by their landlord, can report requests, upload documents and sign the documents submitted to them. Garentiz is not a party to the lease.
• Tradesperson: consults the jobs entrusted to them and responds to them.
• Rental applicant: sends their application to the landlord through the listing page.
• Referral partner: recommends Garentiz under the terms of the partner programme, which they accept separately.

Garentiz is not a real estate intermediary, agent or manager on behalf of third parties: it does not collect rent, does not hold the rental deposit and does not intervene in the relationship between landlord and tenant.

4. Acceptable use

It is prohibited to use Garentiz to:

• enter data without a legal basis, or data that is manifestly excessive for rental management;
• ask rental applicants for information prohibited by regulations (for example on origin, beliefs, health or the composition of assets beyond what is permitted);
• upload content that is unlawful, misleading, abusive or infringes the rights of third parties;
• attempt to access other accounts' data, disrupt the service, or circumvent its security measures or licence limits;
• resell or make the service available without our written consent.

When you share a property by link, delegate access or share your bank file, you confirm that the recipient needs it and has been informed; you can revoke such access at any time.

5. Your content, signatures and the register

• The documents and data you enter belong to you. You grant us only the right to host and process them in order to provide the service.
• Inventory reports and certain documents (for example a notice to quit) can be signed in Garentiz: a signature drawn on the screen, confirmed for the tenant by a single-use code sent by e-mail, and by text message where applicable. This is a simple electronic signature; the signed document is fixed by its fingerprint (hash). Its evidential value remains a matter for the court to assess.
• The time-stamped register records the actions carried out in Garentiz in a chained, append-only form, checked every night, which makes any alteration detectable. It constitutes technical evidence; its evidential value before a court remains a matter for that court to assess.
• You can export your data at any time from “My data”.

6. Assistant

When the service is enabled and included in your licence, the assistant can read the documents you submit to it (lease, invoice, quote, bank statement, loan agreement or notarial deed, photo of a meter), sort a request, propose a reply or a summary, or write a narrative based on your register. No proposal is applied to your files without your confirmation. Proposals may be incomplete or wrong: check them. No assistant feature reads identity documents. In the texts sent, e-mail addresses, account numbers and phone numbers are masked; submitted documents are sent as they are. Use of the assistant is capped each month according to your licence. How the assistant works and who provides it are described in the Privacy Policy.

7. Availability and changes

We make our best efforts to keep Garentiz available and reliable and to protect your data (encryption of identity documents and secrets, daily backups, two-factor authentication, audit log). Interruptions may occur for maintenance or in the event of an incident; we announce them whenever possible. We may change the features; a change that substantially reduces a current paid licence will be notified to you in advance.

Some features rely on third-party services (sending e-mails and text messages, phone notifications, Google or Apple login, maps, indices published by Statbel, payment); if these are unavailable, those features may be temporarily limited.

8. Liability

General rules. Garentiz's calculations, templates and reminders are general aids, not individual legal advice: you check the data you enter and the use you make of the results. We are liable for damage caused by a breach of our obligations, in particular for a calculation error attributable to Garentiz (indexation, notice, final statement, deposit…), which is the performance of our main obligation. We are liable for our subcontractors built into the service (sending e-mails and text messages, payment, hosting). We are not liable for genuinely external services you choose to use (your bank, a public service), nor for their unavailability without fault on our part, nor for force majeure. Nothing in these terms excludes or limits our liability for fraud, gross negligence, failure to perform an essential obligation, or where the law prohibits it.

If you are a consumer. No other limitation applies: you benefit from the legal conformity guarantee for digital services (art. 1701/1 et seq. of the former Civil Code) and the mandatory rules of the Code of Economic Law.

If you act in a professional capacity. Apart from fraud, gross negligence and failure to perform an essential obligation, our liability is limited to direct damage, excluding slight negligence, and capped at the fees paid for the service during the twelve months before the event giving rise to the damage.

9. Suspension and closing of the account

• You can delete your account at any time from “My data”. Deletion takes effect 30 days after your request; during this period, you can cancel it. Exporting your data remains a right during those 30 days, never a sanction. What is deleted, anonymised or kept is described in the Privacy Policy.
• We may suspend an account in the event of a serious breach of these terms, fraudulent use or a security risk. Except in an emergency (security, fraud), we first inform you in writing and give you a reasonable period to remedy the situation. In the event of non-payment, suspension only follows a formal notice that has remained unanswered for 15 days. No suspension is decided “at our sole discretion”.

10. Changes to the terms

• The terms you accepted on subscribing, or at the last renewal, apply for the whole paid period. A new version only applies to a paid licence at its next renewal; it is notified to you at least 30 days before the deadline to object to the renewal.
• During the period, we only change the service or the terms for a valid reason (change in the law, security, technical necessity), at no cost to you. If such a change has a negative impact that is not minor, you may terminate free of charge within 30 days of being informed, and the unexpired part of your batch is refunded pro rata.
• The accepted version and its date are kept for each account.

11. Applicable law and disputes

These terms are governed by Belgian law. In the event of a dispute, we favour an amicable solution (support@garentiz.com). If you are a consumer, you may bring proceedings before the court designated by article 624, 1°, 2° or 4° of the Judicial Code, in particular that of your domicile, and you may contact the Consumer Mediation Service (Service de Médiation pour le Consommateur) free of charge (www.mediationconsommateur.be). If you act in a professional capacity, the courts of the judicial district of Hainaut, Mons division, have exclusive jurisdiction.
