What these terms cover
Proper Spreadsheets checks spreadsheets you already have, for free or on a paid plan, and makes new spreadsheets, described in your own words or bought ready made. These terms are the agreement between you and us when you use this website.
Who we are
Proper Spreadsheets is run by Proper Spreadsheets Ltd, 71-75 Shelton Street, Covent Garden, London, WC2H 9JQ, United Kingdom. The company is registered in England and Wales, company number 17522267. The address above is its registered office.
These terms were last changed on 18 October 2026.
Checking a spreadsheet
A check reports the problems its rules find and says what it could not read. A report with nothing in it is not a promise that the spreadsheet is right. Keep your original file.
Checking a spreadsheet: paid plans
Paid plans are billed in advance through Stripe, monthly or yearly, until you cancel. A year costs ten months' price. Prices are on the pricing page and on Stripe's page before you pay. You can cancel at any time from your account, and the plan then runs to the end of the period already paid for. Deleting your account ends the subscription at once, with no refund for the rest of the period.
The Solo plan starts with seven days free, once for each account and once for each card. Your card is charged when they end unless you cancel first, and we email you three days before. Practice and Firm have no free week. Moving to either during the free week ends it, and the new plan is charged from that day.
If you subscribe as a consumer, the law gives you fourteen days from subscribing to cancel. The plan starts straight away because you ask it to, so if you cancel in that time we refund what you paid less a fair share for the days you had it after the free week. Write to us to ask.
If we change a plan's price, we will email you before it applies, and you can cancel before it does.
The person who subscribes owns the account and is responsible for the people they invite. When a plan ends, the findings it kept are deleted.
Checking a spreadsheet: a certificate
A certificate costs £9.99. After paying, you choose the same file again and we check it once more: if that check is clean the certificate is issued, and if it finds anything we refund the payment. You can do this for 30 days after paying.
A certificate covers that one version of the file and the mistakes our checks look for. It is not a review by an accountant. Once it is issued the sale is final, but the law's protection for something faulty still applies.
Checking a spreadsheet: other people's information
If a file you check holds information about other people, you are its controller and we are your processor. We process it only to run the checks you ask for, keep it confidential and secure, delete it when the check or your plan ends, and use only the companies named on the privacy page, telling you before we add one. We will help you answer requests about it and meet your other obligations, tell you without delay of any breach, and give you what you need to show these promises are kept.
By sending a file, or a link to one, you confirm you are allowed to have it checked.
Making a spreadsheet
One payment buys the spreadsheet on the screen when you pay, as an Excel file you download and keep, to use, change, copy and share as you like. Changing it after paying makes a different spreadsheet and a separate payment. The price is shown before you pay and again on Stripe's page.
Cells that calculate are locked so that a formula is not overwritten by accident. There is no password, so you can unlock them in your own spreadsheet program.
Making a spreadsheet: no refunds
There are no refunds. Every tab, every column and every formula is on the screen, free, before you pay, and you can change it as many times as you like first.
By paying you ask for the file straight away, and accept that once it has downloaded you lose the fourteen day right to cancel an online purchase.
If the file will not open, or is not the spreadsheet you were shown, your rights under the Consumer Rights Act 2015 still apply. Write to us.
Your account
An account is for people aged 18 or over. Keep your email and any passkey or authenticator app to yourself. You are responsible for what is done on your account.
Using it fairly
Do not use the service for anything unlawful, send a file meant to cause harm, get round a limit, a payment or a plan, copy the site or its templates in bulk, or take it apart except as the law allows. If somebody does, we may refuse their requests, or suspend or close their account. If we close a paid account for any other reason, we refund the part of the period paid for and not had.
What belongs to whom
Your spreadsheets are yours. The website, the checks and the software behind them, the template designs, and the name and logo are ours.
What we are responsible for
We are responsible for loss you suffer that was a foreseeable result of our breaking these terms or not taking reasonable care. A check and a spreadsheet are tools, not accounting, tax, legal or financial advice, so check figures that matter yourself.
If you use the service for a business, we are not responsible for lost profit, business or data, and our total responsibility in any year is limited to what you paid us in the twelve months before the problem arose.
Nothing in these terms limits responsibility for death or personal injury caused by negligence, for fraud, or for anything else the law does not allow to be limited. Nothing in these terms takes away rights you have by law.
Changes
We may change the service and these terms. If we stop a paid plan, or take away something it includes, we will tell you first and refund any part of a period paid for and not provided. If a change to these terms matters to a paid plan, we will email you before it applies, and you can cancel before it does.
The contract and disputes
The contract is made in English when you pay on Stripe's page, where you can check and correct your details before you confirm. These terms stay on this page.
Write to us first, at the address at the end of this page, and we will try to put it right. These terms are governed by the law of England and Wales, and its courts deal with any dispute. If you are a consumer living in Scotland or Northern Ireland, you can bring a claim in your own courts instead.
