Terms of Service

Effective 19 August 2026

These terms are an agreement between you and LumoSheet ("we", "us"). They cover the LumoSheet application at app.lumosheet.com, the lumosheet.com website, and any self-hosted deployment we license to you. By creating an account, signing in, or using the service, you accept them. If you accept on behalf of a company, you confirm you are authorized to bind that company, and "you" means that company.

1. What the service does

LumoSheet is a platform for collecting and deciding on vendor campaign submissions. A buying organization configures a campaign, invites supplier contacts, receives line items online or as Excel workbooks, and records an accept, reject, or revision decision on each one. The service sends notifications about those events on your behalf.

We may change, add, or remove features. If a change removes a capability you are actively relying on, we will give at least 30 days notice by email to your organization's administrators.

2. Accounts, seats, and administrators

Your workspace is an organization. Internal users, campaign managers and administrators alike, consume a licensed seat. Supplier contacts do not: supplier accounts are unlimited and free on every plan, and we will not begin charging your suppliers for access to your campaigns.

• You are responsible for everything done under your organization's accounts, including who you grant administrator rights to. An administrator can read every campaign in your workspace, manage users, and download the entire workspace.
• Accounts are for named individuals. Do not share credentials.
• Keep your contact addresses current. Notices about billing, trial expiry, and pending deletion go to your administrators by email.
• Tell us promptly if you believe an account has been compromised.

3. Free trial

A self-serve trial gives you the Standard plan for 14 days with 3 seats and no payment card. When the trial ends without a purchase:

• Your workspace becomes read-only and your campaigns are archived. Nothing is deleted at this point, and you can still sign in and export your data.
• 60 days after expiry, the workspace and everything in it is permanently deleted: campaigns, submissions, uploaded files, and any user account whose only tie was that workspace.
• We email your administrators when the trial ends and again 7 days before deletion.
• Purchasing a plan at any point before deletion restores full access with nothing lost.

Deletion at the end of that window is permanent and we cannot reverse it. Export your data before then if you want to keep it.

4. Fees, billing, and cancellation

Paid plans are billed monthly in advance per licensed seat through Stripe, our payment processor. Card details go to Stripe and never reach our servers. Prices are exclusive of taxes, which are added where required.

• Adding seats mid-period is prorated. Removing seats takes effect at the next renewal.
• You can cancel at any time from the billing portal. Cancellation takes effect at the end of the period you have already paid for. We do not refund partial months.
• If a payment fails or a subscription lapses, your workspace becomes read-only until billing resumes. A paid workspace is never automatically deleted.
• We will give at least 30 days notice by email before any price increase, and it takes effect at your next renewal.

5. Your content

Everything you and your suppliers put into the service, campaign configurations, submitted line items, uploaded files, and the accounts themselves, is yours. We claim no ownership of it.

You grant us a limited, non-exclusive license to host, store, transmit, scan, and display that content strictly to operate the service for you: rendering it in the app, generating your Excel templates and exports, scanning uploads for malware, and sending the notifications you configure. That license ends when the content is deleted.

We do not sell your content, share it with advertisers, or use it to train machine learning models.

6. Acceptable use

Do not use the service to:

• Upload or transmit malware, or content that is unlawful, infringing, or that you have no right to share.
• Attempt to reach another organization's data, another supplier's items, or any account you were not granted. Probing the boundaries between tenants is a violation whether or not it succeeds.
• Interfere with the service: load testing without written permission, circumventing rate or size limits, or reverse engineering except where law permits it.
• Resell or provide the service to a third party as your own, unless we have agreed to it in writing.

We may suspend an account or a workspace that is causing harm to the service or to another customer. Where the situation allows it, we will tell you first and give you a chance to fix it.

7. Your suppliers

You decide which suppliers to invite and what each contact may see. The relationship with your suppliers is yours, and you are responsible for the accuracy of what you tell them and for having the right to invite them. Supplier contacts use the service under these terms as well, limited to the campaigns and vendor tags granted to them.

8. Availability and support

We aim to keep the service available and to give reasonable notice of planned maintenance, but Standard and Business plans carry no service level agreement. Enterprise agreements can include one, in writing. Support is by email, with priority handling on Business and Enterprise plans.

9. Security

We separate every organization's data at the data layer, scan every upload for malware before it can be downloaded, hash passwords, encrypt stored single sign-on secrets, and log every mutation to an audit trail you can read. No system is perfectly secure, and we do not warrant that the service cannot be breached. If a breach affects your data, we will notify your administrators without undue delay and tell you what we know.

10. Getting your data out, and deletion

Any administrator can download the entire workspace as one Excel workbook at any time, on any plan, with no request and no fee. After your agreement ends, you keep read-only access for 30 days so you can export. You can also ask us to delete your workspace sooner, and we will do it within 30 days of the request. Backups are overwritten on their own schedule and are purged within 35 days.

11. Confidentiality

Each side may learn confidential information from the other. Both sides agree to protect it with at least the care they use for their own confidential information, and to use it only for this agreement. This does not cover information that is public, already known, independently developed, or that must be disclosed by law, in which case we will tell you if we are permitted to.

12. Our intellectual property

The service, its software, and the LumoSheet name and marks are ours. These terms grant you a right to use the service, not any ownership of it. If you send us feedback or suggestions, we may use them without obligation to you.

13. Disclaimer

Except as stated in these terms, the service is provided "as is" and we disclaim all implied warranties, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the service will be uninterrupted or error free, and the service is a tool for running your process, not advice about your commercial decisions.

14. Limitation of liability

Neither side is liable for indirect, incidental, special, or consequential damages, or for lost profits, revenue, or data, even if told such damages were possible. Our total liability under this agreement is capped at the fees you paid us in the 12 months before the event that gave rise to the claim. These limits do not apply to your payment obligations, to either side's breach of confidentiality, or to anything that cannot be limited by law.

15. Indemnity

You will defend and indemnify us against third-party claims arising from your content, your use of the service in breach of these terms, or your relationship with your suppliers. We will defend and indemnify you against third-party claims that the service infringes their intellectual property. In each case the indemnified side must give prompt notice and reasonable cooperation.

16. Term and termination

This agreement runs while you have an account. You may terminate by cancelling your subscription or asking us to close your workspace. We may terminate for a material breach you do not fix within 30 days of written notice, or immediately for the acceptable use violations in section 6. Sections that by their nature should survive, including confidentiality, intellectual property, disclaimers, liability limits, and indemnities, survive termination.

17. Changes to these terms

We may update these terms. For material changes we will email your administrators at least 30 days before they take effect, and the effective date at the top of this page will change. Continuing to use the service after that date means you accept the update. If you do not, you may cancel before it takes effect and we will refund any prepaid, unused fees.

18. General

This agreement is governed by the laws of the United States, without regard to its conflict-of-law rules, and both sides submit to the exclusive jurisdiction of its courts. Neither side may assign this agreement without the other's consent, except in a merger or sale of substantially all assets. If a provision is unenforceable, the rest stands. A failure to enforce a right is not a waiver of it. These terms and any written order form are the entire agreement between us and replace any prior discussion. Neither side is liable for delays caused by events beyond its reasonable control.
