Lustrum Terms of Use

Lustrum is software for running a shop’s ordering week: setting a weekly budget, splitting it into a band per vendor, working the order lists, photographing invoices at the door so the paper is filed against the delivery it came with, and keeping what is owed in one place. It is a web application plus a phone app for the staff who are on the floor.

It is a record-keeping and planning tool. It is not a point of sale, it is not an accounting system, it does not file anything with anybody, and it does not move money. Nothing in Lustrum is financial, tax or legal advice, and the figures in it are only as good as what was put into it.

You may use Lustrum if you work for a store that subscribes to it, you are old enough to work in your jurisdiction, and you have been given an account by Lustrum or by that store.

There is no public sign-up. If you have arrived here without an account, nothing on this site is an offer to give you one.

An account belongs to the store, not to the person holding it. When somebody leaves, the store keeps the record of what they did and can close the account.

Keep your password to yourself and do not sign in as somebody else. Turn on two-factor authentication if your store asks you to. Tell your owner or manager, and us, if you think an account has been taken.

What an account can see and change is set by its role. Owners and managers see the money; a staff account signs in to the work. Working around that boundary is a breach of these terms rather than a clever use of the product.

The store’s records stay the store’s. Its vendors, invoices, deliveries, plans, cheques and photographs are its own business record. We hold them to run the service, we do not sell them, and we do not show one store’s records to another.

You grant us only the permission we need to run the service for you: to store those records, to show them back to the people in your store who are allowed to see them, to back them up, and to work on them when you ask us to fix something.

We may use aggregated, de-identified information that cannot be traced back to a store or a person to understand and improve the product. If we ever want to do more than that, we will ask first.

Ask us for your data and you will get it. Leave, and we will return it or delete it. What we hold and for how long is set out in the privacy policy.

That what you put in is accurate, and that you have the right to put it in. If you photograph an invoice, you are the one saying that invoice is yours to hold.

That the people you give accounts to should have them, and that you remove the ones who should not.

That you keep your own copies of anything you cannot afford to lose. We back the service up and we take that seriously, and it is still your business record.

You agree not to:

• Sign in as somebody else, or share an account with somebody who should have their own.
• Try to reach data belonging to a store you do not work for.
• Probe, scan or test the security of the service except as described below, or work around any limit or access control it applies.
• Scrape the service, or use it through anything other than the interfaces we provide.
• Upload anything you have no right to upload, or anything containing malicious code.
• Overload the service deliberately, or use it in a way that degrades it for other stores.
• Resell the service, hold it out as your own, or use it to build a competing product.
• Reverse engineer it, except where a law says you may despite this sentence.

If you find one, tell us through our contact form before telling anyone else, and give us a reasonable chance to fix it. Do not access anybody else’s data to prove a point, and do not run anything destructive. We will not pursue somebody who reports a problem in good faith and follows that.

We work to keep Lustrum up and to keep your data safe. There is no uptime guarantee on this page, and its absence is deliberate: a number nobody has measured is worth nothing to you. The service can go down, and it needs maintenance windows.

Support is by our contact form. We answer as quickly as we can, and we will tell a store directly when something is wrong rather than waiting to be asked.

Features change. We add things, and occasionally we remove something that is not working. If we remove something a store depends on, we will tell it first.

A store pays per store, per month, at the price agreed with it. Pricing shown on this site is what a new store would pay today; a store already on a price keeps that price until we tell it otherwise, with reasonable notice before the change takes effect.

A pilot store pays nothing while it is a pilot store, and we will say clearly when that ends rather than letting it turn into a bill.

Lustrum, its software, its design and its name are ours. These terms give you the right to use the service, not to own any part of it, and nothing here transfers any of it to you.

Anything you tell us about how the product should work, we may act on freely and without owing you anything for it. We would rather hear it than not.

Lustrum is built with open-source software, used under its own licences. Some of the motion on this site is built from Skiper UI components, used under their free tier, which requires this attribution.

This section is where that attribution lives. It sat in the footer of every page until 2026-08-27 and moved here so the footer could carry the legal links instead: the licence asks to be credited, not to be credited in a particular place.

Where a store connects Lustrum to a system it already runs, that system has its own terms and we are not a party to them.

The service is provided as it is. To the extent the law allows, we do not promise it will be uninterrupted, error-free, or fit for a purpose you have in mind and have not told us about.

Lustrum helps you keep a record and plan a week. It does not decide what to order, it does not check that an invoice is correct, and it does not replace somebody looking at the numbers. Decisions made from what it shows you are yours.

A store can stop at any time, and so can we, with reasonable notice on either side.

We can suspend an account immediately, without notice, if it is being used to break these terms or to put another store’s data at risk. We will say why, and we will restore it if we were wrong.

Either way, the store’s data is returned or deleted on request. The sections about ownership, your data and disclaimers survive the end of these terms; nothing else needs to.

When these terms change materially we will change the date at the top and tell the stores it affects. Carrying on using Lustrum after a change means the new terms apply. If you do not agree to a change, tell us and stop using the service, and we will not hold you to the new terms for the period before you did.

Anything about these terms goes to our contact form and we will answer it.

Lustrum is early, and the company that will operate it is still being formed. When it is, its legal name, registered address and the law these terms are governed by will be named here rather than left to be guessed at.
