Terms of Service

These terms are the agreement between you and Nifdi Systems Limited (“nifdi”, “we”, “us”) for the nifdi website, the nifdi diagram editor, the nifdi cloud services and the nifdi integrations (together, the “Service”). By using the Service you accept these terms. If you accept them on behalf of an organisation, “you” means that organisation, and you confirm you have authority to bind it.

Nifdi Systems Limited is a company registered in England and Wales. Company number 14782393. Registered office: Jubilee House, East Beach, Lytham St. Annes, England, FY8 5FT. Contact us at support@nifdi.app.

1. What the Service provides

Nifdi is software for creating and editing diagrams. We provide this software as the Service.

We do not provide consultancy, design services or professional advice, and nothing the Service produces is advice. Any information obtained from the Service may be incorrect, so check details before relying on them.

2. Plans

Free. The free plan offers a basic set of features. What it includes may change, and it carries no service commitment.

Paid plans. Paid plans offer additional features. Each plan’s contents and price are set out on our pricing page, which forms part of these terms.

We may change what a plan includes. If a change materially reduces what you are paying for, we will give you at least 30 days’ notice, and you may cancel and receive a refund for the unused part of your current billing period.

3. Your account

You need an account to use the editor and the cloud service. Give us accurate details, keep your credentials private, and tell us promptly if you suspect someone else has accessed your account. You are responsible for all activity under your account. The Service is designed and marketed as a professional tool and is not directed at children.

4. Acceptable use

You agree not to use the Service to:

• break the law or help anyone else break it, or infringe anyone’s rights, including intellectual property rights;
• deceive people, including phishing, fraud, scams, or pretending to be someone you are not;
• publish anyone’s personal or confidential information without their permission, including passwords, access keys and leaked data;
• harass, threaten or abuse anyone;
• send spam, or use shared diagrams to host files for use elsewhere;
• store or distribute malware, or content that is unlawful, abusive or deliberately harmful;
• attack, probe, overload or interfere with the Service or anyone else’s use of it, or circumvent any limit, quota or access control;
• resell, sublicense or provide the Service to third parties as your own product;
• copy, decompile or reverse engineer the Service, except to the extent the law says you may;
• use scripts or agents to place a load on the Service far beyond what one person and their own agents would ordinarily generate; or
• return under another account after we have suspended yours.

This covers what a diagram is used for, not only what it contains.

If we reasonably believe this section is being breached, we will do the least that deals with the problem: removing others’ access to a diagram, stopping you from sharing, removing content, or suspending your account. When sharing is restricted, nothing is deleted, and you do not lose access to your own diagram. We may act without warning where waiting would cause harm, for example when content is used for phishing or exposes personal information; otherwise we will ask you to put it right first. Any restriction goes only as far, and lasts only as long, as the problem requires. This proportionate approach does not apply to content we determine to be illegal, which we swiftly remove from the Service.

How we handle illegal content

We do not currently use automated scanning or other proactive technology to identify illegal content. When a report or other information gives us reason to suspect that content may be illegal, a person reviews it. We handle the principal categories as follows:

• Terrorism content: we treat the report as urgent, restrict access while necessary to assess it, and swiftly remove content we determine to be illegal.
• Child sexual exploitation and abuse content: we treat the report as urgent, restrict access while necessary to assess it, swiftly remove content we determine to be illegal, and preserve or report it to the appropriate authority where the law requires.
• Other priority illegal content: including fraud, threats, harassment, hate offences, intimate image abuse, unlawful weapons or drugs content, and content encouraging suicide or serious self-harm, is assessed promptly and swiftly removed if we determine that it is illegal.

These rules apply whether content is shared widely or only with particular people.

Reports, complaints and reviews

Anyone, whether or not they have a nifdi account, can report content they believe is illegal or breaches this section by emailing abuse@nifdi.app. Include the diagram link or other identifier if you have it, what you believe is wrong, why, and any supporting information. We assess reports, may ask for more information, take appropriate action, and tell the reporter the outcome where we can.

We may restrict or remove content, restrict sharing, or suspend the account responsible. If we act against your content or account, we will tell you what we did and why no later than when we do it, unless the law, an investigation, or another person’s safety prevents us. You can ask us to review that decision by the same email address. Users and other people affected by content can also use that address to complain about illegal content, how we handled a report or review, or whether we have complied with our online-safety duties. We consider the information provided, take any appropriate corrective action, and communicate the outcome where we can.

Fair use for unlimited cloud diagrams

“Unlimited” means that we do not set a routine numerical limit on the number of cloud diagrams a paid user may create for ordinary use of nifdi as a diagramming service. It does not turn the Service into general-purpose file or image storage, a backup or archive service, or a content delivery service.

If your use is primarily for one of those other purposes, materially exceeds ordinary diagramming use, or risks the capacity, security or availability of the Service, we may apply reasonable limits to storage, file size, request rates or other capacity. Unless immediate action is needed to prevent harm, we will contact you first and give you a reasonable opportunity to reduce your usage or export your diagrams. Any restriction will be proportionate to the problem and will last only as long as necessary.

5. Your diagrams

You keep all rights in the diagrams, text, images and other material you put into the Service (“Your Content”). We claim no ownership of it.

You grant us a worldwide, non-exclusive, royalty-free licence to host, store, copy, transmit, render and display Your Content, and to make backups of it, strictly to the extent needed to operate and support the Service for you and the people you share with, to enforce these terms and to comply with the law. The licence ends when Your Content is deleted, except for backup copies, which are overwritten in the ordinary backup cycle.

We do not use Your Content to train AI models. We read it only as our Privacy Policy describes: when you ask us to, to repair or restore it after a fault, to act on a report under section 4 or a security incident, or when the law requires it.

You confirm you have the rights you need in Your Content. We do not monitor it, and we are not responsible for it.

Sharing. The owner of a cloud diagram decides who can view or edit it. Everyone you share with needs a nifdi account, verified with the email address you shared the diagram with, and everyone with access to a diagram can see the others’ email addresses. You can change or remove someone’s access at any time, with immediate effect. Edits made by people you share with become part of your diagram, and you remain its owner.

Personal data in your diagrams. If Your Content includes personal data that you or your organisation controls, you are responsible for having the right to put it there, and we process it on your behalf only to provide the Service. We separately act as controller for account, security, support and legal-compliance processing described in our Privacy Policy. If you need a data processing agreement, email us before uploading that personal data.

What not to store. Do not store passwords, keys or other secrets in diagrams, or data requiring special regulatory handling, such as health or payment card data. The Service is not designed for it.

6. Third-party intellectual property

The Service includes libraries of icons published by third parties for you to use in diagrams to the extent their owners permit. The Service records each icon’s owner and licence, and keeps that record with any diagram that uses it. Those icons remain their owners’ property and are subject to their owners’ terms. We grant you no rights in them beyond what their owners grant, and you are responsible for complying with those terms when you publish or distribute a diagram that uses them. Product and company names shown in the Service are trademarks of their respective owners, and their appearance implies no endorsement or affiliation.

7. Our intellectual property

The Service, and everything in it other than Your Content and third-party material, belongs to us or our licensors. We grant you a limited, non-exclusive, non-transferable, revocable right to use the Service as these terms allow, for as long as your account is in good standing. Components of nifdi published under an open source licence are governed by that licence.

8. Feedback

We may use any ideas or suggestions you send us without restriction, payment or obligation of confidentiality, so do not include anything confidential in feedback.

9. Agents and integrations

If you connect an AI agent or other third-party tool to your diagrams, you are responsible for that tool and for what it does with your data, including anything it sends to an AI provider. We are not responsible for third-party services, and you connect them at your own risk.

An agent token acts with your permissions, so anything done with it is treated as done by you. Protect agent tokens as you would a password; if one is exposed, tell us and we will revoke it.

10. Previews and experimental features

Features labelled beta, preview or experimental are provided as is, may change or be withdrawn without notice, and are excluded from any commitment in these terms.

11. Payment

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns. Paddle is the seller for the purchase and handles payment, all applicable taxes, receipts and invoices, subscription cancellation, withdrawals, refunds, chargebacks and other transaction-related questions. Nifdi Systems Limited supplies and licenses the Service and handles product, technical, account and data support. Your purchase is subject to Paddle’s buyer terms as well as these.

Subscriptions are billed in advance, in the currency shown at checkout, and renew automatically at the end of each billing period until you cancel. You authorise Paddle to charge your payment method for each renewal. Prices are as shown at the time you subscribe; we may change them for future billing periods with at least 30 days’ notice, and you may cancel before the change takes effect. Refunds are governed by our Refund Policy.

If a payment fails, Paddle may retry it. We may suspend paid features if Paddle tells us that your subscription is unpaid or no longer active.

12. Cancelling, and what happens to your work

You can cancel at any time. Cancellation takes effect at the end of the billing period you have already paid for, and you keep paid features until then.

Cancelling never deletes your diagrams or locks them in. Cloud diagrams beyond the limits of your new plan become read-only, and you can still export any diagram.

If you close your account, we delete your content within 30 days, as our Privacy Policy describes. Export anything you want to keep first.

13. Termination by us

We may suspend or end your access if you materially break these terms and do not put it right within 14 days of us asking, if you do not pay, or if the law requires it. Unless the law or the nature of the breach prevents it, you can still export your diagrams for 30 days afterwards. We may also withdraw the Service as a whole, on at least 30 days’ notice, refunding the unused part of anything you have paid.

14. Availability and support

We take reasonable care to keep the Service available, but we do not guarantee uninterrupted or error-free operation, and there is no service level agreement unless we have signed one with you separately. Maintenance, third-party outages and faults will occur.

Product, technical, account and data support is by email at support@nifdi.app. For payment, tax, receipt, cancellation or refund questions, use the support link in your Paddle receipt or visit Paddle.net. We aim to respond to paying customers within three working days; this is a target, not a contractual guarantee.

Keep your own copies. We take backups and work hard not to lose anything, but you should export work that matters to you. Our liability for lost content is limited as set out in section 16.

15. Warranties

If you are a consumer, nothing in this section affects your statutory rights, including your right to a service provided with reasonable care and skill.

Otherwise, except as these terms expressly say, and to the fullest extent the law allows, the Service is provided “as is” and we exclude all implied warranties, including those of merchantability, fitness for a particular purpose and non-infringement.

16. Our liability

Nothing in these terms limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be limited.

Subject to that, and to the extent the law allows:

• we are not liable for loss of profit, loss of business, loss of goodwill, or for any indirect or consequential loss; and
• our total liability arising out of or in connection with the Service, in any 12-month period, is limited to the greater of the amount paid for the Service in that period and US$100.

If you are a consumer, you have legal rights that these terms do not affect, and we are not liable for losses that were not foreseeable when you agreed to these terms. If you use the Service for business purposes, the limits above apply in full.

17. Changes to these terms

We may change these terms. The date at the top shows the current version. If a change materially affects your rights, we will give account holders at least 30 days’ notice by email or in the product, and continuing to use the Service after it takes effect means you accept it. If you do not accept a change, cancel before it takes effect and we will refund the unused part of your billing period.

18. General

These terms, the Privacy Policy, the Refund Policy and the plan description on our pricing page are the whole agreement between us about the Service. We may transfer our rights and obligations under them to another business; you may not without our consent. If any part is found unenforceable, the rest remains in effect. A delay in enforcing these terms is not a waiver of them.

We are not responsible for failing to meet these terms because of events beyond our reasonable control. You may not use the Service if you are subject to UK sanctions, or in a way that breaks UK sanctions or export control law.

We send notices to the email address on your account. Send yours to legal@nifdi.app.

These terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction. If you are a consumer resident elsewhere in the United Kingdom or in the European Union, you keep the protection of the mandatory laws of the country you live in and may bring proceedings there.
