Terms of sale & use

Last updated: 9 August 2026

These terms apply when you buy or use DATUM digital products — Revit templates, families, plugins and their documentation. They are written to the European consumer rules listed at the end, and nothing in them removes a right those rules give you.

1. Who you are dealing with

The producer and licensor of the products is DATUM, a Revit template and plugin studio operated from Sofia, Bulgaria. Contact: support@datumbim.com. The registration details required of any online seller are on the company details page, which states openly which of them are not complete yet.

Payment is taken by a payment provider, which is named on the checkout page before you pay and on the receipt you are sent. Where that provider acts as merchant of record, the sales contract for that transaction is concluded with them: they collect payment, charge and remit any VAT, and issue your invoice. DATUM grants you the licence to use the product and provides support and updates for it. Where these terms and the provider's purchase terms both apply, each governs its own part of the transaction; a right you have as a consumer applies against whichever of us is responsible for the matter concerned, and you may address a complaint to us either way. Changing provider does not change these terms and does not affect a licence you already hold.

You need a DATUM account to buy. It is where your licence key stays readable, where you release a seat from a machine you no longer have, and where you download again what you have paid for. The address on the account is the address the purchase is recorded against, so it must be one you can receive mail at.

You must be 18 or over. These are professional tools sold under a contract, and they are neither made for nor offered to children. You confirm your age when you open the account, on the same tick as accepting these terms and the Privacy policy. An account we find to belong to someone under 18 is closed and the personal data deleted — see section 8 of the Privacy policy, which says exactly what that means and how to tell us.

If you are buying for a company, a studio or a practice, you also confirm you are entitled to enter into this contract on its behalf.

2. What the products are, and how they are delivered

Every product is digital content supplied without a tangible medium. There is nothing to ship. On payment you receive, by e-mail and in your DATUM account, a download and — for plugins — a licence key. Plugins install into Revit as a DATUM ribbon tab and activate by entering that key.

Supply happens at the moment the files are made available to you for download or the licence key is issued, whichever is first.

What you need before buying. Windows 64-bit, and Autodesk Revit. Which release depends on what you are buying, because the two are built differently:

• Plugins — Revit 2022 to 2027. One installer carries a separate build for each of those six releases and puts the right one into every Revit it finds on the machine. They are tested on all six.
• Templates — Revit 2024 and later. Built in 2024. Revit will not open a file made in a release newer than the one you are running, so 2024 is the floor rather than a preference: on 2022 or 2023 the file will not open at all. Write to us before buying, not after.

macOS is not supported for either. Where a product page states a different or additional requirement, that statement governs.

The plugins are a beta. Every version of the DATUM BIM add-in released so far, including the current one, is a beta build. It is labelled as such on the plugins page, on the download, in the licence window and in the manual. That is a description of what you are getting, not a disclaimer: section 5 applies in full, and a beta that does not do what this site says it does is not in conformity. What it does mean is that the description you can hold us to is a beta's — commands and interfaces may still change between versions, and the product is not presented as a finished one. Templates are not beta; they are finished products.

3. Price, VAT and invoices

Prices are shown in EUR. Other currencies shown on the site are an indicative conversion for reading only; the charge is made in EUR. Whether VAT is added, and at what rate, is determined at checkout by the payment provider from your country and, for businesses, from a valid VAT number. Your invoice comes from that provider; a copy is available from us on request to support@datumbim.com.

4. Your right of withdrawal, and how it can be lost

If you are a consumer in the EU, you normally have 14 days to withdraw from a distance contract without giving any reason, under Directive 2011/83/EU as amended by Directive (EU) 2019/2161. The period runs from the day the contract is concluded.

For digital content not supplied on a tangible medium, that right is lost only if all three of the following happened — this is Article 16(m) of the Directive, and it is read strictly:

• you gave prior express consent for performance to begin during the withdrawal period;
• you acknowledged that you would thereby lose your right of withdrawal; and
• we or the payment provider confirmed that consent and acknowledgement to you on a durable medium.

At checkout you are asked to tick both statements before the download and the key are released. If you did not tick them, or if you did not receive the confirmation, your 14-day right stands and we will refund you in full.

To withdraw, write to support@datumbim.com with your order number and a clear statement that you are withdrawing. You may use the model withdrawal form in Annex I(B) of the Directive, but you do not have to. We refund using the same means of payment you used, within 14 days of being informed, at no cost to you.

Beyond the statutory right. If a product genuinely does not do what its page says it does, tell us — we would rather refund you than argue about which day it is.

The refunds page says all of this in plain language and sets out how to claim, along with the separate conformity right in section 5 below — which is not lost by downloading and cannot be waived at all.

5. If something is wrong with the product

Under Directive (EU) 2019/770 we owe you digital content that matches its description, is fit for its purpose, and comes with the updates needed to keep it that way. This is a legal guarantee, it costs nothing, and it sits alongside — not instead of — anything else on this page.

• Two years. We are liable for a lack of conformity that becomes apparent within two years of supply.
• The first year, we prove it. If the fault shows up within the first year, you do not have to prove it was there at supply; we have to prove it was not.
• Remedies, in order. First we bring the product into conformity, free and within a reasonable time. If that is impossible, disproportionate, fails, or we do not do it, you may ask for a proportionate price reduction or terminate the contract and be refunded. For a fault that is not minor you may go straight to termination.
• Updates. We will inform you of and supply the updates, including security updates, needed to keep the product in conformity for as long as you can reasonably expect given its type and purpose. Plugins check for updates themselves and install them; you can switch that off, but if you do, a fault caused by not installing an update we told you about is not ours.

6. Licence

You get a non-exclusive, non-transferable licence to use the product in your own work. Templates and families are bought outright and the licence for them is perpetual. Plugins are not sold outright: the licence for them is monthly, it lasts as long as it is paid, and the tools stop unlocking when it lapses — though anything you drew or exported with them stays yours. Neither transfers ownership of the files or of the intellectual property in them. The full grant, the seat counts and the limits are in the Licence terms, which form part of these terms.

7. Support and updates

Support is by e-mail, in Bulgarian or English, from Sofia. We aim to answer within two working days.

Fixes for the Revit version you bought for are free and unlimited in time. A new annual Revit release is a new product edition: whether an upgrade is included depends on the product page and on your tier or subscription at the time. Nothing here reduces our obligations under section 5.

8. Subscriptions

Plugin licences bill monthly until you cancel. You can cancel at any time from your DATUM account or by writing to us; access continues to the end of the period already paid for, and no further payment is taken. Cancelling stops future charges — it is not in itself a request for a refund of a period already used.

Templates and families are not subscriptions. They are bought once, and the licence for them does not lapse.

9. What the products do not promise

This section does not touch section 5. The legal guarantee of conformity is not something we are allowed to disclaim, and we are not trying to. What follows is about the things beyond conformity that software of this kind is often claimed to guarantee and cannot.

The products are professional tools, not a substitute for professional judgement. Drawings, schedules, specifications and calculations they produce must be checked by the qualified person who signs them, against the norms in force for that project. Beyond their description, and to the extent the law allows, the products are supplied as they are, and we do not promise:

• that any output complies with any particular norm, standard, building regulation or authority requirement — including where a tool is named after one;
• that they are free of every defect, or that any specific defect will be fixed;
• that they will run uninterrupted, or that the licence server, the update service or the website will be available at any given moment;
• that they are fit for a purpose you have not told us about, or that they suit your office's particular workflow, template or naming conventions;
• that they will work with a Revit version, an operating system, a third-party add-in or a hardware setup outside the requirements stated in section 2, or after Autodesk changes something we do not control;
• that a file, model or project will not be altered in a way you did not intend. Keep backups. The tools write into your model, and an undo is not a backup.

Where you are a consumer, none of this reduces the two-year legal guarantee, the burden of proof in the first year, the remedies, or the update obligation in section 5, nor anything else the law gives you and does not let us take away.

10. Limitation of liability

What is never limited. Nothing in these terms limits or excludes our liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, for gross negligence or wilful misconduct, for anything else that cannot lawfully be limited, or for your rights as a consumer under sections 4 and 5. If any part of this section is held to be unenforceable, the rest still applies.

What we are not liable for. To the extent the law allows, we are not liable for indirect or consequential loss, nor for loss of profit, revenue, business, contracts, anticipated savings, goodwill or reputation, nor for loss or corruption of data, models or drawings, nor for wasted time or the cost of redoing work — whether or not we were told such loss was possible.

The cap. To the extent the law allows, our total liability arising out of or in connection with a product, whether in contract, tort (including negligence), breach of statutory duty or otherwise, is limited to the greater of: the total amount you actually paid us for that product in the twelve months before the event giving rise to the claim, or EUR 100.

The cap is deliberately close to what the products cost. These are tools priced in tens of euros a month that are used inside projects worth a great deal more, and the price does not, and could not, carry the risk of the projects. If you need cover beyond this, it belongs in your professional indemnity insurance, not in a EUR 9 monthly licence — write to us and we will say so in writing for your insurer.

11. Your responsibility to us

This section applies only if you are using the products in the course of a business, trade, craft or profession. It does not apply to consumers, and nothing in it is asserted against a consumer.

If you are such a user, you agree to indemnify us — meaning to cover our reasonable costs, including legal costs, and any award or settlement — against claims brought by a third party that arise out of:

• your use of a product in breach of these terms or of the licence terms;
• output you issued, signed, submitted or relied on without the check required by section 9;
• content, families, templates or data you loaded into or distributed with a product, where that content infringes somebody's rights;
• your sharing of a licence key or of the products with anyone the licence does not cover.

This does not apply to any part of a claim caused by our own breach, negligence or wilful misconduct. We will tell you promptly about any claim we want covered, will not settle it without asking you first, and will let you take over the defence if you want it and can conduct it properly.

12. Ending this agreement

You may end it at any time. Cancel a subscription from your account or by writing to us; it stops the next payment and access runs to the end of the period you have paid for. You can close your account entirely by writing to support@datumbim.com — see the Privacy policy for what is deleted and what we are obliged to keep. None of this is a request for a refund; refunds are sections 4 and 5.

We may suspend or end it, on notice where notice is possible, if you:

• do not pay for a subscription and do not put it right within 14 days of being asked;
• share, publish, resell or sublicence a licence key or the products outside the licence;
• work around, remove or interfere with the licensing, activation or update mechanisms;
• use the products unlawfully, or in a way that damages the service for other customers.

We will suspend before we terminate wherever that is a real option, and a suspension is lifted as soon as the cause is. For a first breach that looks like a misunderstanding you will hear from a person before anything is switched off.

What ending it does. Plugin licences stop unlocking the tools. Templates, families and anything else bought outright are not withdrawn — that licence is perpetual and stays so, and we will supply the files again on request even after an account is closed. Anything you drew, scheduled or exported with any of it stays yours, permanently and without condition.

What survives. Sections 9, 10, 11, 13 and 14, any payment already owed, and any term that by its nature is meant to outlast the agreement.

13. Complaints and dispute resolution

Write to support@datumbim.com first. Most things are settled that way.

If we cannot agree, and you are a consumer, you may take the matter to an alternative dispute resolution body under Directive 2013/11/EU. In Bulgaria these are the conciliation commissions at the Commission for Consumer Protection (Комисия за защита на потребителите, kzp.bg), which also takes consumer complaints directly. If you live in another EU country, your national ADR bodies and the European Consumer Centre in your country can help.

The European Commission's online dispute resolution platform was shut down on 20 July 2025 and Regulation (EU) No 524/2013 was repealed. There is deliberately no link to it here; anyone still showing one is pointing customers at a dead page.

You may also always go to court.

14. Governing law

These terms are governed by the law of the Republic of Bulgaria. If you are a consumer habitually resident in another EU or EEA country, this choice does not deprive you of the protection of the mandatory rules of your own country's law, and you may bring proceedings in the courts of your country of residence — Article 6 of Regulation (EC) No 593/2008 (Rome I) and Article 18 of Regulation (EU) No 1215/2012.

15. Changes

We may change these terms for future purchases. The version that applies to your purchase is the one published when you bought. Material changes affecting an ongoing subscription will be notified by e-mail before they take effect, and you may cancel if you do not accept them.

16. The rules these terms follow
