Terms and Licence
What you may do with Vertical Tabs, what is promised about it, and what happens if something goes wrong. Written to be read, not to be skipped.
Version 1.0 · In force from 14 September 2026
The short version. One purchase gives one person a permanent licence to use Vertical Tabs on up to two computers. Updates are included. Try it free for seven days before paying, and ask for a refund within 30 days if it disappoints. The software is provided as it is, and if it ever costs you anything, the most that can be claimed back is what you paid for it.
1Who you are dealing with
Vertical Tabs is made and licensed by STRUCTURES.LV SIA, a limited liability company registered in Latvia under number 41203065119, VAT number LV41203065119, with its registered office at Džohara Dudajeva gatve 11 – 72, Rīga, LV-1084, Latvia (“we”, “us”). You can reach us at support@excelverticaltabs.com.
Payment is not taken by us. Our order process is run by Paddle.com Market Ltd, which is the merchant of record for every purchase: Paddle sells the licence to you, charges you, handles VAT and sales tax, and is the party named on your receipt. Your purchase is therefore also subject to Paddle’s Buyer Terms. Where those terms and these ones disagree about payment, billing or tax, Paddle’s terms win. Everything on this page about how you may use the software is between you and us.
By installing or using Vertical Tabs you accept these terms. If you do not accept them, uninstall the software and do not use it.
2The free trial
Vertical Tabs runs for seven days from first launch without a licence key, with every feature available. No payment details are needed to start the trial, and nothing is charged when it ends — the sheet pane simply stops listing sheets until a key is entered.
The trial is counted per computer, and offered once per computer. It exists so you can find out whether the software suits your workbooks before paying for it. Please do use it for that.
3What your licence allows
When payment completes you receive a licence key by email. That key grants you a permanent, worldwide, non-exclusive licence, which does not expire, to:
- install and use Vertical Tabs on up to two computers that you personally work on — typically a work machine and a home machine;
- use it for any purpose, personal or commercial, including on the workbooks of the company you work for;
- install any later version of Vertical Tabs that your key continues to unlock (see section 4).
A licence covers one person on up to two computers — not one company, and not a machine shared between colleagues. If you replace a computer, the licence moves with you: uninstall it from the old one and the replacement does not count as a third.
Vertical Tabs does not check how many machines a key has been used on, and it makes no network call when it validates: the check happens entirely on your own computer. That is a deliberate design choice, so the software keeps working on locked-down corporate networks and through any outage on our side. The two-computer limit is therefore a matter of trust rather than enforcement, and we would rather say so plainly than pretend to a check we do not perform.
If several people at an organisation will use Vertical Tabs, buy a licence for each of them. For ten or more, write to us and we will arrange a single invoice rather than make you buy them one at a time.
4Updates
Updates and fixes are included at no extra cost, and your key unlocks them. We intend to keep every existing key valid for as long as Vertical Tabs is sold, and we have no plans to charge for an upgrade. We are not, however, promising any particular update, any release schedule, or that the software will be developed indefinitely. If we ever do release a paid major version, your key keeps working on the version it already unlocks — a licence you have bought is never taken away.
5What your licence does not allow
You may not:
- share, publish, sell, rent, sub-license or give away your licence key, or use a key you were not issued;
- resell or redistribute Vertical Tabs itself, or bundle it into another product, without our written agreement;
- work around, disable or tamper with the trial or the licence check;
- remove or alter any copyright, author or licence notice in the software;
- decompile, disassemble or reverse engineer the software, except exactly as far as applicable law permits despite this restriction — in the EU that includes the interoperability rights under Directive 2009/24/EC, which these terms do not attempt to remove.
Vertical Tabs is licensed to you, not sold to you. We keep all copyright and other intellectual property in it. You keep everything in your own workbooks: using our software gives us no rights over your files whatsoever.
6Refunds
If Vertical Tabs is not what you hoped, tell us within 30 days of purchase and we will refund it in full. No reason needed, no forms. Email support@excelverticaltabs.com from the address you bought with, or claim it directly through Paddle. The refund is made by Paddle, to the payment method you used.
This is offered on top of your legal rights and does not affect them. If you are a consumer in the EU or UK you normally have 14 days to withdraw from a distance purchase; because the licence key is delivered immediately, that right is exercised through the same route, and our 30-day promise is the longer of the two in any case. The seven-day trial exists so that you can evaluate the software without needing any of this.
7No warranty
Vertical Tabs is provided as it is. We have tested it and we use it ourselves, but we do not warrant that it will be uninterrupted or error-free, that it will work with every version of Excel, every other add-in, or every workbook, or that it will meet any particular requirement of yours. To the fullest extent the law allows, all implied warranties and conditions are excluded.
Please keep backups. Vertical Tabs can rename, hide, unhide and reorder the sheets in an open workbook, because that is what it is for. Those are changes to your own file, and Excel’s undo does not always reach actions taken by an add-in. Work the way you would with any tool that edits your documents, and keep a copy of anything you cannot afford to lose.
8Liability
To the fullest extent permitted by law, our total liability to you for everything arising out of Vertical Tabs or these terms is limited to the amount you actually paid for your licence.
We are not liable for indirect or consequential loss, loss of profit, loss of business or revenue, loss of anticipated savings, or loss of or damage to data, however arising.
Nothing in these terms limits or excludes liability that cannot lawfully be limited or excluded — including liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, and, if you are a consumer, any of your mandatory statutory rights. If you are a consumer, nothing here removes your right to a remedy where the software is not as described or not of satisfactory quality.
9Support
Support is by email at support@excelverticaltabs.com. We answer as promptly as we reasonably can, and we would much rather hear about a problem than have you quietly ask for a refund. Lost your key? Email us from the address you bought with and we will send it again.
10Ending the licence
Your licence lasts indefinitely. It ends only if you materially breach section 5 — for example by publishing your key — and do not put it right within 14 days of us asking you to. If it ends, you must stop using Vertical Tabs and uninstall it. You may end it yourself at any time by uninstalling, which does not by itself entitle you to a refund outside section 6.
11Your data
The add-in sends nothing anywhere: no telemetry, no account, and none of your workbook contents ever leave your computer. What we hold is only what a purchase creates — your name, your email address and the key we issued you. The privacy policy sets out all of it.
12Changes to these terms
We may update these terms for future purchases. The version in force on the day you bought is the version that governs your licence, and the date at the top of this page tells you which that is. We will not change your terms retrospectively. If you want a copy of the version you bought under, ask us for it.
13Law and disputes
These terms are governed by the laws of Latvia, and the courts of Latvia have jurisdiction. If you are a consumer, this does not deprive you of the protection of the mandatory consumer law of the country you live in, and you may also bring proceedings in your own country’s courts. EU consumers can use the European Commission’s online dispute resolution platform, though emailing us first is very likely to be faster.
