Totsum — Website Terms of Use

Revision 2026-09-10 — Effective date: 10 September 2026

Mandatory EU and Belgian consumer-protection rules override any conflicting clause below. Nothing here is intended to reduce a statutory right.

1. Who we are

This website at totsum.app (the “Website”) is operated by Totsum SRL, a société à responsabilité limitée incorporated in Belgium, registered office Avenue Kersbeek 308, 1180 Uccle, Belgium, enterprise number 1041.093.971 (RPM Bruxelles, Tribunal de l’entreprise francophone de Bruxelles), VAT number BE 1041.093.971 (“Totsum”, “we”, “us”).

Contact: hello@totsum.app. Our full legal mentions are on the imprint page.

2. What these terms cover — and what they don’t

These terms set out the conditions on which we make the Website available: browsing it, reading the documentation, downloading the software, and asking for a free trial key. They do not govern your purchase or your use of the software. Simply reading this website is not treated as concluding a contract with us. Where the law requires acceptance before something happens, it is asked for expressly: the licence agreement before a key is issued — on this website, by a box that is not pre-ticked, on the pricing page for a purchase and on the page we link from our e-mail for a free trial key — and shown again by the installer; and Paddle’s terms at checkout.

Three separate documents apply, each within its own scope:

• The software — the EULA, the licence agreement between you and us.
• Purchases — concluded with Paddle, our reseller and merchant of record, under Paddle’s buyer terms. Our refund policy describes your withdrawal, conformity and refund rights and how requests are handled.
• Personal data — the privacy policy, a transparency notice rather than a contract.

3. Using the Website

You may use the Website for its intended purpose: learning about Totsum Data Explorer, consulting the documentation, evaluating and downloading the software, asking for a free trial key, applying for the private beta or joining the waiting list, and buying a licence. You must not:

• attempt to gain unauthorised access to the Website, its hosting infrastructure, or any connected system;
• interfere with its operation, including by knowingly introducing malicious code or imposing an unreasonable load;
• scrape, harvest, or reproduce the Website’s content in bulk by automated means, except as permitted by Section 4 or by applicable law;
• misrepresent your affiliation with Totsum, or present the Website’s content in a way that suggests endorsement by us.

4. Intellectual property, crawling and AI training

The Website and its content — text, documentation, graphics, logos, page design, and the Totsum name and mark — are owned by Totsum or its licensors and protected by intellectual-property law. You may view, download, and print pages for your own use, including internal business use such as evaluating the software. Any other reproduction or reuse requires our prior written permission, except where applicable law or a licence stated on the relevant page permits it. No rights in the software are granted through the Website; it is licensed exclusively under the EULA.

What we permit, deliberately. To the extent of our own rights in the Website’s content, we permit crawling, indexing, retrieval, and text and data mining — including use of that content to train or ground AI models — for the crawlers and paths allowed by our robots.txt at the time of access. Third-party material on the Website (fonts, sample data, the AI model’s own documentation) stays under its own licence. This is a considered choice: the site exists to explain what the software does, and we would rather it be described accurately by an assistant than not at all. We do not reserve our rights under Article 4(3) of Directive (EU) 2019/790 in respect of those pages and crawlers. This permission may be changed prospectively by changing that file, and it does not permit republishing or redistributing the Website, reproducing a substantial part of it as a substitute for it, using our marks, or accessing any crawler or path robots.txt disallows.

5. Information on this Website

We prepare the Website’s content in good faith, but it is general information rather than professional advice, may contain errors or become outdated, and may change at any time. Hardware compatibility guidance is indicative: whether the software performs acceptably on a specific machine can only be established by testing, which is what the free trial is for. This does not limit the conformity rights you have as a consumer in respect of software you have bought, nor any other mandatory statutory right.

6. Downloads and the free trial

Installers downloaded from the Website are licensed under the EULA, including its trial provisions. The software does not run without a licence key: the free trial key is issued by e-mail once you have accepted the EULA on the page we link from that e-mail — downloading is not accepting. One trial is available per person, and the service will not issue more than one trial key to the same e-mail address. Installation and the AI model it provisions are described in the privacy policy and the documentation. We do not guarantee continuous availability of the Website or of downloads, subject to mandatory law.

7. Purchases

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns. Paddle is the seller of record; it processes payment, determines the checkout currency, applicable taxes and final price, and issues the invoice. The amount confirmed at checkout governs.

Questions about the software itself come to us. A defect, a technical problem, or a claim that the software does not conform is ours to investigate and fix — that is the division set out in EULA §14, which also explains that this division describes who does what between Paddle and us and does not decide who is answerable to you under the law that applies to you. If you send something to the wrong one of us, we will pass it on.

Refund and withdrawal information is in our refund policy; your statutory rights remain unaffected.

8. Third-party links and services

The Website links to third-party websites and services (for example Paddle, or the mediation service in Section 11). We are not responsible for their content or practices; your use of them is governed by their own terms.

9. Changes to the Website and to these terms

We may modify or discontinue any part of the Website at any time, other than the pages the EULA commits us to keep — the security advisories page and the published revisions of the agreement (its Section 9.3). We may also update these terms; the version in force, with its effective date, is the one published on this page, and it applies to use of the Website from that date onwards. It does not apply retroactively, and does not affect purchases already concluded, the EULA under which you acquired a licence, or any right you have already acquired. If an updated version does not suit you, you are free to stop using the Website at any time — there is nothing to cancel and nothing to pay.

10. Liability

If you are a consumer, our liability in connection with the Website is governed by the mandatory rules of the applicable law. Nothing in these terms limits it, and nothing here affects your rights in respect of software you have bought — those are addressed in the EULA, the refund policy, and by your statutory rights.

If you are not a consumer, then to the extent permitted by applicable law we are not liable for indirect or consequential loss, loss of profit, loss of business, or loss of data arising from use of, or inability to use, the Website or its content. This does not exclude liability for direct damage caused by our fault, but our total aggregate liability for such damage is limited to EUR 500. Liability in connection with software you have licensed is not governed by these terms at all — it is addressed in the EULA, which has its own limits.

Nothing in these terms excludes or limits liability for fraud or intentional fault; for gross fault by Totsum or a person for whom Totsum is responsible; for death, personal injury or harm to physical or psychological integrity; for a failure to perform an essential obligation, to the extent that applying an exclusion or cap would deprive these terms of their substance; for liability under mandatory product-liability law; or for any other liability that cannot be excluded under Belgian law — including the applicable mandatory Belgian rules governing unfair terms in consumer contracts and, separately, between businesses.

11. Governing law and disputes

These terms are governed by Belgian law. If you are a consumer, that choice does not deprive you of the protection of the mandatory rules of the law of your country of habitual residence.

If you are not a consumer, the courts of Brussels, Belgium, have exclusive jurisdiction, except where mandatory law provides otherwise. If you are a consumer, jurisdiction is determined by the mandatory rules that apply to you — within the EU these generally allow you to bring proceedings in your own Member State, and generally allow us to bring proceedings only there.

Consumer mediation. If you have a complaint, please write to us first at hello@totsum.app. If we cannot resolve it, a consumer may contact the Belgian Consumer Mediation Service (Service de Médiation pour le Consommateur / Consumentenombudsdienst):
