Terms of use

Last updated: 13 November 2026

These terms are the agreement between Vizualinx and the agency that uses Properlinx: the website, the web app and the iPhone and Android apps. The data processing agreement at the end of this page is part of them. We kept them as plain as we could, but they are binding, so please read them before you start.

1. Who we are and how these terms apply

Who we are. Properlinx is made by Vizualinx, the trade name of Elli Grossman, a sole trader established in Belgium, registered with the Crossroads Bank for Enterprises under enterprise number 1028.348.666, at Zonnewijzerstraat 9, 2018 Antwerp, Belgium. In these terms, “we” and “us” mean Vizualinx. You can reach us at hello@properlinx.com.

Who “you” are. “You” and “the agency” mean the business that uses Properlinx, such as a property management agency. Properlinx is made for businesses and is not offered to consumers.

Users. The people the agency lets into its workspace are its users: its owners, office staff and in-house workers, and the contractors, landlords and tenants it invites. Users are not a party to these terms. Section 3 says what applies to them.

Accepting. These terms apply from the moment an agency is created in Properlinx, someone accepts an invitation to become an agency’s owner, or the agency starts to use Properlinx, whichever comes first. They also apply during a free trial. Whoever accepts them for the agency confirms that they are allowed to bind it.

What the agreement is made of. In this order of priority:

• a written agreement signed by both of us, if there is one;
• the price and conditions the agency’s owner accepts in the app, or in a written offer from us;
• these terms, including the data processing agreement. On data protection, the data processing agreement comes first.

The agency’s own purchasing or general terms do not apply.

2. The service

What Properlinx is. An online service that helps property management agencies run maintenance and the work around it: repair reports, jobs, quotes, approvals, planning, hours, tasks, chat, documents, certificates and inspections, among others. We provide it as a service: the agency gets access, not a copy of the software.

What it is not. Properlinx is a tool. It gives no legal, tax, accounting, payroll or technical advice, and it does not move money. Quotes, invoices, rent and payments in the app are records: the payments themselves happen outside Properlinx, for example from the agency’s own bank. Figures the app works out, such as hours, overtime, gross wages, VAT on quotes, deadlines and certificate dates, help you but don’t replace your own check. Reminders help you meet deadlines. The deadlines stay yours.

Changes to the service. We keep improving Properlinx and can add, change or remove features. If we remove or substantially reduce a feature the agency relies on, we tell its owners at least 30 days in advance, unless security or the law makes us act sooner. If the change is a real disadvantage for the agency, it can end the subscription before the change, and we refund what it paid in advance for the period after the end.

Features switched on per workspace. Some features are new, in testing (beta) or off by default, such as the AI connector. We decide for which agencies they are available, and we can switch them on or off for a workspace. Beta features can be incomplete, can change or stop without notice, and are left out of what section 8 says about availability. Within what is available, the agency’s owner decides in Settings what is switched on. Switching a feature off deletes nothing.

AI features in the app. When they are switched on for a workspace, some features use an outside AI service: Linx (typed, spoken or with a file), voice-to-text, AI report import and dashboard suggestions. They send the request, and the agency data the answer needs, to that service. Each person is asked once before their first use. Annex A6 names the services. AI answers can be wrong: check them before you rely on them. The AI connector is something else: see section 7.

Linx in the support chat. This is off by default, and it is not switched on per workspace: we switch it on for all of Properlinx. When it is on, Linx answers messages in the Properlinx support chat from our help guides, and can suggest to our support staff how to sort a message. The message and the recent messages of that conversation go to one of the AI services named in annex A6.

Services of others. Parts of Properlinx depend on other companies’ services, such as the app stores, the push services of phones and browsers, sending and receiving email, and Google Maps. Their own terms also apply to how you use them. Apple and Google are not a party to these terms and have no obligations under them.

3. Accounts and users

One account per person. Everyone signs in with their own account: with a code sent by email, with a password if the agency allows passwords, or on the web with Google or Apple. Accounts are personal. Don’t share them.

The agency is responsible for its users. The agency decides whom it invites and which role each person gets, and it is responsible for what its users do in its workspace. When someone leaves or no longer needs access, remove them from the team. They lose access at once.

Owners act for the agency. We may treat what an owner does in Properlinx, and what an owner writes to us from the email address of their account, as the agency’s instruction. For example: switching features on or off, accepting a statement in the app, or asking us for a copy or deletion of data. Keep at least one owner. If an agency is left without an owner, we can invite a new owner after we have checked whom the agency wants.

Keep sign-ins safe. Keep devices, email accounts and passwords secure. If you think an account has been misused, tell us at once at hello@properlinx.com.

If an agency invited you. If you use Properlinx as an agency’s worker, contractor, landlord or tenant, the agency decides what you can see and do, and the information about its jobs belongs to its records. Using Properlinx is free for you. Please follow section 6. Nothing in these terms limits the rights you have as a consumer. How we handle your personal data is on the privacy page.

4. Fees and payment

Prices. The prices on our pricing page apply, including its minimum, unless we agreed a different price in writing or in the app. You pay per billable unit per month. A billable unit is anything that can have a job: a house, an apartment in a building, or a building’s common areas (at most one per building). Landlords, tenants and contractors use Properlinx free. Only the agency pays.

Free trial. A new agency starts with a free trial, with every feature and without bank details. Its length is shown when the agency is created. To keep working after the trial, the owner sets up billing. If not, the workspace can become read-only: the data is kept and everyone can still look at everything, but nobody can make changes.

Billing. We charge in advance for each billing period: a month, or a year if that is agreed. The amount follows the number of billable units on the billing date. Units added during a period are charged from the next period. Units removed during a period count until that period ends. We collect by SEPA direct debit or another method we offer, or we send an invoice, payable within the term stated on it.

VAT. Prices exclude VAT. VAT and other taxes are added where they apply.

No refunds. Fees paid are not refunded, also when the agency uses fewer units or stops during a period, unless these terms say otherwise.

Late payment. If a payment fails or is late, we tell the owners and may try again. If an amount is still unpaid 14 days after we told them, we may make the workspace read-only until it is paid. Under the Belgian Act of 2 August 2002 on late payment in commercial transactions, an unpaid amount carries interest at the rate set by that Act from the day after it was due, without a reminder being needed, plus a fixed compensation of €40 for recovery costs and any further reasonable recovery costs.

Price changes. We can change our prices for a valid reason, for example a change in our costs, in the service or in the law. We tell the owners at least 30 days in advance. A new price applies from the first billing period that starts after that notice. A price agreed for a fixed period stays until that period ends. If the agency doesn’t accept a new price, it can stop renewal before the new price applies.

5. Your data and privacy

Your data is yours. What the agency and its users put into Properlinx is the agency’s data: buildings, units, contacts, jobs, messages, photos, documents, hours and so on. The agency gives us the right to store, process and show it only to provide, secure and support Properlinx for the agency, as these terms describe.

Who is responsible. The information an agency keeps in Properlinx is the agency’s, and the agency is responsible for it. For the personal data in it, the agency is the controller and Vizualinx is the processor: we handle it only for the agency and only on its instructions. The data processing agreement in the annex sets out how, as Article 28 of the GDPR requires. Vizualinx is responsible for user accounts, requests to join and keeping Properlinx running and secure, as the privacy page explains.

The agency’s part. The agency makes sure it is allowed to put personal data into Properlinx and to use the features it chooses, such as the location check at clock-in, the apps for tenants, landlords and contractors, the AI features and the AI connector. It informs the people concerned, such as its staff, workers, tenants, landlords and contractors, where the law requires it. Don’t add special categories of personal data, such as health data, unless a job really needs it and the law allows it.

Usage counts. Once a day we count, per agency, the number of buildings, units, team accounts, jobs this month and storage used. We use these numbers for pricing and to plan capacity. We don’t sell personal data, show no ads and build no profiles.

Privacy page. Which personal data Properlinx handles, where it is stored, who helps us and how long it is kept is on the privacy page.

6. Acceptable use

Use Properlinx for the agency’s business, lawfully and as it is meant to be used. Don’t:

• break the law or other people’s rights, such as their privacy or intellectual property;
• add content that is unlawful, abusive or discriminatory, or that you have no right to use;
• send spam or advertising through Properlinx’s messages, emails or notifications;
• try to get into accounts, workspaces or data that aren’t yours, or test our security without our written consent;
• disrupt or overload Properlinx, get around its limits, or upload malware;
• copy, scrape, resell or rent out Properlinx, or use it to build a competing product;
• take apart or reverse engineer the software, except as far as the law allows.

If you find a security problem, don’t use it: tell us at hello@properlinx.com. We can remove content, or limit access, that breaks this section (section 13).

7. AI connector

What it is. The AI connector lets owners and office staff use their own AI app, such as Claude, ChatGPT or Codex, with their agency’s data in Properlinx. It is optional. We decide for which agencies it is available, and we may switch it off, or change the tools it offers, at any time.

The AI app is not part of Properlinx. The AI app is a separate service, used under the agency’s or the person’s own agreement with its provider, for example Anthropic for Claude, or OpenAI for ChatGPT and Codex. We don’t provide, control or check the AI app, its answers, or what its provider does with the data it receives. That is covered by the provider’s terms and privacy policy. The provider is not one of our sub-processors (annex A11).

Reading. A connected AI app can read what the connected person can see in Properlinx, within the limits on the privacy page. Each person connects for themselves and approves the connection on a consent screen. The agency decides who in the agency may connect an AI app, and it is responsible for being allowed to share that data with the AI app’s provider.

Action tools. An AI app can only act in Properlinx if we offer action tools to the agency, and the agency’s owner turns them on and accepts the responsibility statement for the agency. The AI app can then, for example, create jobs and tasks, add notes, message the people on a job, assign and schedule work, ask for quotes, accept or turn down quotes, and close jobs. It can only do what the connected person is allowed to do.

What the agency accepts. By turning action tools on, the agency accepts that:

• every action counts as done by the person who connected the AI app, with that person’s permissions in Properlinx;
• AI makes mistakes, and it can be misled by text it reads, such as a message from a tenant or the description of a job (prompt injection);
• some actions, such as a sent message or an accepted quote, can’t always be undone;
• some AI apps run tools without asking first, for example during research;
• the agency decides who may use action tools, checks what its AI apps do, checks what they propose before approving it, and is responsible for the result.

Our responsibility. We don’t review these actions. As far as the law allows, we are not liable for what an AI app does or fails to do, for how the AI app’s provider handles data, or for the result of actions taken through the connector once the agency turned action tools on. This doesn’t change the cases in section 12 where liability can’t be limited.

Control and records. The owner can turn action tools off at any time in Settings › AI connector, which stops all actions at once. Every person can disconnect their own AI app, and the owner can disconnect anyone’s. Properlinx logs each use of an action tool, done or refused, with the person, the AI app and the time. In Settings › AI connector the owner sees everyone’s recent entries. If we change the responsibility statement in a way that matters, action tools stay off until the owner accepts the new version.

Security. Keep your AI app account as secure as your Properlinx account. If you think it has been misused, disconnect it in Settings › AI connector and tell us at hello@properlinx.com. We may end a connection that we believe is misused or puts Properlinx or other people at risk.

Personal data. How the connector handles personal data, and when a connection ends, is on the privacy page.

8. Availability, support and backups

Availability. We work to keep Properlinx available and fast, but we can’t promise that it will always work without interruptions or errors. It also depends on the internet, our providers and the app stores. There is no service level agreement (SLA) unless we agreed one in writing.

Maintenance. Properlinx sometimes needs updates and maintenance. We try to do this at quiet times and to warn the owners in advance when we expect a noticeable interruption. Urgent security fixes can happen without warning.

Apps and browsers. Keep the mobile apps and your browser up to date. Old app versions and old browsers can stop working.

Support. Write to hello@properlinx.com, or use the support chat in the app where it is available. We answer on Belgian working days, as soon as we reasonably can. To help with a support question, a Properlinx administrator can open the agency’s account in read-only mode. Each time is logged with a reason.

Backups and data loss. We take reasonable measures to protect the agency’s data against loss, but we can’t promise that data can always be restored in full after an incident. Keep your own copy of what the law requires you to keep, such as invoices and payroll records.

9. Intellectual property and feedback

Ours. Properlinx, its software, design and texts, and the Properlinx name belong to Vizualinx or its licensors. During the subscription, the agency and its users may use Properlinx for the agency’s business under these terms. This right is not exclusive and can’t be transferred. Nothing else is transferred.

Yours. The agency’s data stays the agency’s. We get no rights to it other than those in section 5.

Feedback. If you send us ideas or suggestions, we may use them freely, without any obligation to you.

10. Confidentiality

Each of us keeps the other’s confidential information confidential and uses it only for this agreement. Confidential information is information that is marked as confidential or that should reasonably be understood to be, such as the agency’s data, the prices we offer the agency and non-public information about Properlinx.

This doesn’t apply to information that becomes public without the receiving party’s fault, that it already had or lawfully got from someone else, or that it developed itself. Either of us may disclose information when the law, a court or an authority requires it, and tells the other first where that is allowed.

This duty lasts for 3 years after the agreement ends, and for the agency’s data as long as we hold it.

11. What we promise, and what we don’t

What we promise. We provide Properlinx with the care and skill of a professional service provider. This is an obligation of means, not of result.

What we don’t promise. As far as the law allows, we make no other promises. In particular, we don’t promise that Properlinx will work without interruptions or errors, that it meets every need of the agency, or that the results of calculations, AI features or other companies’ services are correct or complete.

What the agency promises. The agency has the right to the data it adds and may let us process it under these terms, and it uses Properlinx in line with the law.

12. Liability

Limit. Our total liability towards the agency, for all claims together, under or in connection with this agreement, is limited to the higher of: the fees the agency paid us for Properlinx in the 12 months before the first event that caused the damage, or €500.

No indirect damage. As far as the law allows, we are not liable for indirect or consequential damage, such as lost profit, turnover, savings or goodwill, business interruption, or claims of others against the agency.

What isn’t limited. These limits don’t apply to damage caused by our fraud, intentional fault or gross negligence, to death or personal injury caused by our fault, or where the law doesn’t allow a limit.

Tell us quickly. Tell us in writing as soon as possible about damage you hold us liable for, so that we can limit it.

Force majeure. Neither of us is liable for not performing because of events beyond its reasonable control, such as failures of the internet, the power grid or our providers’ services, natural disasters, epidemics, war, strikes or measures of authorities. This doesn’t suspend payments already due. If such an event lasts longer than 30 days, either of us can end the agreement in writing.

Claims of others. The agency is responsible towards us for claims of others, such as its users, tenants, landlords, contractors or authorities, that result from the agency’s data, its instructions, or use of Properlinx by the agency or its users that breaks these terms or the law. It compensates us for the reasonable costs of such claims.

13. Term, suspension and ending

Term. The agreement starts when these terms apply (section 1) and runs until it is ended. A paid subscription renews automatically for the same period, a month or a year, until it is stopped.

Ending by the agency. The owner can stop renewal at any time, in the app or by writing to hello@properlinx.com. The subscription then ends at the end of the period already paid, and nothing more is charged. A trial ends by itself.

Ending by us. We can end the agreement:

• for any reason, with at least 3 months’ written notice. We then refund what the agency paid in advance for the period after the end;
• at once, by written notice, if the agency seriously breaks these terms and doesn’t put it right within 14 days after we asked, or if it can’t be put right;
• at once, by written notice, if an amount is still unpaid 30 days after we told the owners that it was due.

Suspension. We can make the workspace read-only, or limit access, if an amount is unpaid as described in section 4, to prevent or stop a security risk or misuse, if a user seriously breaks section 6, or if the law or an authority requires it. We do this only as far and as long as needed, and we tell the owners, in advance where we can. Fees stay due during a suspension for non-payment or a breach.

At the end. When the agreement or the paid period ends, the workspace becomes read-only: people can still sign in and look at everything, but no changes can be made. The data is kept. Amounts already due stay due. Paid fees are not refunded, except as this section and sections 2, 14 and A6 say. What by its nature should continue after the end, such as confidentiality, liability and these rules on data, continues.

The agency’s data after the end.

• A copy: during the subscription, and up to 90 days after it ends, an owner can ask us at hello@properlinx.com for a copy of the agency’s data. We send it free of charge within 30 days, in a common machine-readable format (such as CSV or JSON), with the files.
• Deletion: when an owner asks, we delete the agency’s data within 30 days, except what the law requires us to keep. Copies in our backups disappear when those backups are replaced in their normal cycle.
• If nobody asks: we may delete the agency’s data 12 months after the end. We tell the owners by email at least 30 days before.
• Personal accounts: each person’s own account stays until that person deletes it, in Profile › Security › Delete account.

14. Changes to these terms

We can change these terms for a valid reason, for example new features, a change in the law or in our providers, or security. We tell the owners by email, and in the app, at least 30 days before a change that is to the agency’s disadvantage takes effect. A change the law or security requires can apply sooner. A change that is only to the agency’s advantage, or only a matter of wording, can apply at once.

If the agency doesn’t accept a change, it can stop renewal before the change takes effect. If it paid for a year, it can instead end the subscription before the change takes effect, and we refund what it paid in advance for the period after the end. If the agency keeps using Properlinx after the change takes effect, the new terms apply. The date at the top shows the current version. We send earlier versions on request.

15. Law, courts and general terms

Belgian law. Belgian law governs these terms and the agreement.

Courts. We first try to settle a disagreement by talking. If that doesn’t work, the courts of Antwerp, Belgium, have exclusive jurisdiction.

Languages. These terms exist in English, Dutch and French. If the versions differ, the English version prevails.

Whole agreement. The documents in section 1 are the whole agreement between us about Properlinx. They replace earlier proposals and discussions.

Invalid provisions. If a provision is invalid or can’t be enforced, the rest stays in force. The provision is then replaced by a valid one that comes as close as possible to its purpose.

No waiver. If one of us doesn’t enforce a right straight away, it doesn’t give up that right.

Transfer. The agency may not transfer this agreement without our written consent. We may transfer it to a company we set up to run Properlinx, or to whoever takes over Properlinx. We tell the owners first, and the agency can then end the agreement. We may use subcontractors. For personal data, annex A6 applies.

Notices. We send notices to the email addresses of the agency’s owners or of its billing contact, and may also show them in the app. Send notices to us at hello@properlinx.com or by registered letter to Zonnewijzerstraat 9, 2018 Antwerp, Belgium.
