Terms of Service
Last updated: 30 May 2026
These Terms of Service ("Terms") govern your use of Sufleur — including our website at sufleur.com, our command-line interface, our API, and our documentation (together, the "Service"). By creating an account, publishing prompts, installing prompts, or otherwise using the Service, you agree to these Terms.
If you don't agree to these Terms, please don't use the Service.
These Terms are a legal agreement between you and Sufleur ("we", "us", "our"). If you have any questions, email us at support@sufleur.com.
1. Definitions
- "Account" — the user account you create to access the Service.
- "Workspace" — a container for prompts, members, and billing. Workspace names form part of public install identifiers (e.g.
@workspace-name/prompt-name). - "Prompt" — structured prompt content you author, version, and publish to a Workspace via the Service.
- "Version" — a specific, semantically-versioned snapshot of a Prompt.
- "Public Prompt" — a Prompt that has been published with public visibility, accessible to anyone with the install identifier.
- "Private Prompt" — a Prompt accessible only to members of its Workspace.
2. Eligibility and accounts
You must be at least 16 years old to create an account.
You are responsible for keeping your account credentials secure and for activity that occurs under your account. You may belong to multiple Workspaces, and each Workspace operates independently for billing and access purposes.
3. Acceptable use
When using the Service, you agree not to:
- Use the Service for any unlawful purpose or in breach of any applicable law
- Upload, publish, or distribute content that infringes the intellectual property rights of others
- Upload, publish, or distribute content that contains malware, exploits, or other malicious code
- Use the Service to send spam or unsolicited communications
- Attempt to gain unauthorised access to the Service, other accounts, or any related systems
- Scrape, crawl, or systematically extract content from the Service except via the documented API
- Interfere with the operation of the Service or other users' use of it
- Resell or sublicense the Service without our written permission
- Use the Service in any way that could damage, disable, or impair it
We may impose reasonable rate limits and usage caps — particularly on the free tier — to prevent abuse and ensure fair access for all users.
4. Your content and intellectual property
Your ownership
You retain all rights in the Prompts you create. We don't claim ownership of your content.
Licence to us
To run the Service and deliver it to you (and to other users for Public Prompts), you grant us a worldwide, royalty-free, non-exclusive licence to host, store, transmit, display, and process your content. For Public Prompts, this licence extends to making the Prompt available for installation, search, and discovery via the Service.
Public Prompt default licence
When you publish a Prompt as a Public Prompt without specifying your own licence in the Prompt's licence field, the following default licence applies to that Version:
Any person obtaining access to this Public Prompt is granted a worldwide, royalty-free, perpetual, irrevocable licence to use, copy, modify, distribute, and integrate the Prompt for any purpose, including commercial use, with no obligation to provide attribution. The Prompt is provided "as is", without warranty of any kind.
If you do specify a licence in the Prompt's licence field, that licence governs the Prompt instead of this default.
You acknowledge that once a Public Prompt Version is published, the licence terms for that Version cannot be retroactively changed — only the licence on future Versions can differ.
Our intellectual property
We retain all rights in the Service itself — the platform, the website, our brand, and our trademarks. These Terms don't grant you any rights to use them. The open-source Sufleur CLI is separately licensed under the MIT licence; its use is governed by that licence, not these Terms.
5. Publication and registry permanence
Sufleur is a prompt registry. Other users may install and depend on the Public Prompt Versions you publish. To make that dependency meaningful, we treat Public Prompt Versions as durable once published, with limited withdrawal rights as follows.
Withdrawal of Public Prompt Versions
You may withdraw a Public Prompt Version (delete it from the registry, or make it private) only in the following circumstances:
- Within 72 hours of publication: you may withdraw the Version freely, for any reason. This is intended to let you correct accidental or mistaken publications.
- After 72 hours, if the Version has had no install activity in the preceding 30 days: you may withdraw the Version, subject to a 7-day notice period. During the notice period, the Version remains installable, but users installing it will see a clear warning that the Version is scheduled for withdrawal. After the notice period, the Version is permanently removed.
- In all other cases (i.e. the Version has had install activity in the past 30 days): you may not withdraw the Version. You may instead deprecate the Version (signal that users should move away from it), or where appropriate, transfer ownership of the Workspace to another party.
We may also remove a Public Prompt Version at our discretion if it violates these Terms (for example, if it contains infringing or malicious content), or if we are required to do so by law.
Workspace names
Workspace names form part of public install identifiers. To maintain the integrity of these identifiers, Workspace names you have used for publishing Public Prompts are subject to the same persistence rules as the Public Prompts themselves. We will publish detailed rules for Workspace renaming, ownership transfer, and abandonment as the Service evolves; in the meantime, please contact us at support@sufleur.com to discuss specific cases.
6. Subscriptions, payment, and refunds
Free and paid tiers
The Service offers a free tier and one or more paid subscription tiers. Paid features and limits are described on the pricing page at sufleur.com/pricing.
Payments
Paid subscriptions are processed by our payment partner, Polar, who acts as our merchant of record. By subscribing, you also agree to Polar's terms. Polar handles billing, invoicing, and tax compliance on our behalf.
Subscription terms
Paid subscriptions renew automatically at the end of each billing period unless cancelled. You may cancel at any time from your Workspace settings.
14-day cancellation right
If you are an individual consumer (acting outside your trade, business, craft, or profession), you have a statutory right under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 to cancel a paid subscription within 14 days of the start of the subscription, without giving a reason, and receive a full refund.
If you'd like to access paid features immediately rather than waiting 14 days, you may waive this cancellation right by checking the corresponding box during the subscription flow. If you waive this right and later cancel, you'll be entitled to a refund only for the unused portion of your subscription, calculated on a pro-rata basis.
Pro-rata refunds on discontinuation
If we discontinue a paid feature or the Service as a whole during a billing period you've paid for, we'll refund the unused portion on a pro-rata basis via Polar.
Free tier
The free tier is provided "as is" and may be modified, limited, or discontinued at any time. We do not owe refunds, replacements, or compensation for changes to the free tier.
7. Service availability and changes
The Service is provided on an "as available" basis. We don't guarantee uninterrupted availability, and we may modify, suspend, or restrict access to features at any time. We'll make reasonable efforts to give advance notice of material changes that affect paying users.
Discontinuation of the Service
We may discontinue the Service as a whole, on reasonable notice (at least 30 days for users with active paid subscriptions). On discontinuation:
- We'll provide you with a reasonable window to export your content via the in-app export functionality
- We'll pro-rata refund the unused portion of any active paid subscriptions via Polar
- After the export window, your content may be permanently deleted
8. Termination
By you
You may stop using the Service and delete your account at any time from your account settings. Cancelling a paid subscription stops future billing; subscription benefits remain until the end of the current billing period.
By us
We may suspend or terminate your account if you breach these Terms in a material way, if your subscription payments fail and remain uncured, or if continued provision of the Service to you would expose us to legal risk. Where reasonably practicable, we'll notify you and give you a chance to address the issue before terminating.
Effect of termination
On termination of your account:
- You lose access to the Service
- Your Private Prompts and Workspaces will be deleted in accordance with our Privacy Policy
- Your Public Prompts and Workspace names may be retained in anonymised form to preserve the integrity of the public registry — see Section 5
9. Warranties and disclaimers
The Service is provided "as is" and "as available", without warranties of any kind, express or implied. To the maximum extent permitted by law, we disclaim all implied warranties, including merchantability, fitness for a particular purpose, and non-infringement.
We don't warrant that:
- The Service will be uninterrupted, secure, or error-free
- Any defects will be corrected
- The Service will meet your specific requirements
- Public Prompts available through the Service are accurate, complete, suitable for your use case, or free of intellectual property issues — that's a matter between you and the publisher of the Prompt
If you are an individual consumer, statutory rights that cannot be excluded by law are not affected by this section.
10. Limitation of liability
To the maximum extent permitted by law:
- We will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, data, or business opportunity
- Our total aggregate liability for all claims arising out of or related to these Terms or the Service will not exceed the greater of (a) US$100, or (b) the total amount you paid Sufleur for the Service in the 12 months preceding the event giving rise to the claim
For free-tier use, our maximum aggregate liability is US$100.
Nothing in these Terms limits or excludes our liability for:
- Death or personal injury caused by our negligence
- Fraud or fraudulent misrepresentation
- Any other liability that cannot be excluded under English law
If you are an individual consumer, your statutory rights are not affected by this section.
11. Indemnification
You agree to defend, indemnify, and hold us harmless from any claims, damages, losses, liabilities, and expenses (including reasonable legal fees) arising from:
- Your content (including any Prompts you publish)
- Your use of the Service in violation of these Terms
- Your violation of any third-party right, including intellectual property rights
This obligation doesn't apply to claims caused by our own breach of these Terms or our gross negligence.
12. Changes to these Terms
We may update these Terms from time to time — to reflect new features, address legal changes, or clarify existing language. When we make material changes, we'll notify active users at least 30 days in advance by email and in-app notice. The "last updated" date at the top of these Terms always shows when they were last revised.
If you don't agree to the revised Terms, you may stop using the Service and cancel your subscription before the revised Terms take effect.
13. Miscellaneous
- Entire agreement: these Terms (together with our Privacy Policy and any other policies we publish) form the entire agreement between you and us regarding the Service.
- Severability: if any part of these Terms is held unenforceable, the remainder remains in effect.
- No waiver: our failure to enforce any provision isn't a waiver of our right to enforce it later.
- Assignment: we may assign these Terms in connection with a merger, acquisition, or sale of assets. You may not assign these Terms without our consent.
14. Governing law and disputes
These Terms are governed by the laws of England and Wales. Any dispute arising out of or related to these Terms or the Service will be subject to the exclusive jurisdiction of the courts of England and Wales, except that if you are an individual consumer, you may also bring proceedings in the courts of your country of residence.
