The rules of the road.
Last updated: 12 May 2026 · Effective: 12 May 2026
These terms of service ("Terms") govern your use of the Nifi Notes website at nifinotes.com and the related services we provide, including the tag platform, accounts, and any physical NFC products we sell (together, the "Service").
The Service is operated by Nifi Ltd, a company registered in England and Wales under company number 17127978, with its registered office at 71-75 Shelton Street, Covent Garden, London WC2H 9JQ ("we", "us", "our"). You can reach us at founder@nifinotes.com.
By using the Service, creating an account, or buying a Nifi Note, you agree to these Terms and to our Privacy Policy. If you don't agree, please don't use the Service.
You must be at least 13 years old to use the Service. If you're using the Service on behalf of a business, you confirm that you have authority to bind that business to these Terms.
Nifi Notes is not directed at children under 13, and we don't knowingly collect personal data from children under 13.
You can use parts of the Service anonymously (anyone with a tag URL can write to it). To sync tags across devices, lock tags to your account, or use account-only features, you need to create an account through our authentication provider (Clerk).
You're responsible for keeping your account credentials secure. Don't share your password or sign-in tokens. Tell us promptly at founder@nifinotes.com if you suspect unauthorised use of your account.
You can close your account at any time. We may suspend or close accounts that breach these Terms, as described in Section 11.
Nifi Notes lets you store content (WiFi credentials, notes, logbook entries, market stall layouts, and similar) and link that content to a physical NFC tag or shareable URL. Anyone with the full tag URL can read the content; only people with the encryption key in the URL fragment can decrypt it.
Tag content is encrypted in your browser using AES-256-GCM before it reaches our servers. For users without cloud key sync (anonymous users or those who opt out), the encryption key never leaves the device and we cannot read or recover your content. For signed-in users with cloud key sync enabled (the default), the key is also backed up to your account, enabling cross-device access and assisted recovery upon request. See our Privacy Policy Section 3 for full details.
The Service is currently provided free of charge. Some future features may require a paid plan; if so, we'll make pricing clear before you sign up for any paid feature and update these Terms accordingly.
You keep all rights in the content you upload, write, or store through the Service ("Your Content"). We don't claim ownership of Your Content.
You grant us a limited, worldwide, royalty-free licence to store, transmit, and display Your Content to the extent strictly necessary to operate the Service for you. Tag content is client-side encrypted; for users without cloud key sync, the practical scope of this licence is limited to storing and serving ciphertext we cannot read. For users with cloud key sync enabled, we additionally hold an encrypted copy of the key as described in our Privacy Policy.
You are solely responsible for Your Content. You confirm that you have the rights to store, share, and (where applicable) distribute it — including any photos, drawings, logos, or other material you upload.
You agree not to use the Service to:
Tag content is client-side encrypted. For most users we store only ciphertext and cannot proactively review it. We rely on reports. If you believe a tag contains illegal or abusive content, email us at founder@nifinotes.com with the tag URL and we'll investigate.
Market Stall is currently offered to all signed-in users as a trial-account feature, free of charge. We expect to introduce a paid tier in future; if we do, we will give existing trial-account users reasonable advance notice and a choice about whether to upgrade. Nothing in this section commits us to any particular pricing or feature split.
Customer opt-ins. When a customer opts in to share their email with your stall, we hold that opt-in record on the platform. We are building an in-platform mailing tool so you can communicate with opted-in customers without ever holding the underlying email addresses yourself. Stall owners do not currently export opted-in customer lists. If we add an export feature in future, we will update these Terms and notify affected stall owners first.
Customer communications. When you communicate with opted-in customers (today via Live mode personalised messages and in future via the in-platform mailing tool), you remain responsible for the content of those messages. You must:
Live mode content. When you activate Live mode you can attach a personalised message and an optional receipt image for the next single customer tap. You are responsible for the content of these messages and images. We reserve the right to remove abusive, unlawful, or otherwise prohibited Live mode content; in practice we rely on user reports and our existing admin tools to do so. Live mode content is stored in plain (unencrypted) form on our servers — see our Privacy Policy Section 3 for the full picture and the rationale (remote support for sellers).
Physical Nifi Notes (NFC stickers and related products) are not yet on sale. When we start selling them, separate sale terms covering price, delivery, statutory consumer rights, returns, and warranties will apply at checkout. Nothing in these Terms affects your statutory rights under the Consumer Rights Act 2015.
NFC behaviour depends on your device. Tap-to-connect WiFi using a native NDEF record currently works on Android phones with NFC. iPhones do not natively read WiFi NDEF records written by Android, so on iOS the WiFi tag falls back to a web flow with manual password copy. We provide the Service "as is" with respect to device support.
"Nifi", "Nifi Notes", the Nifi Notes logo, and the tagline "Tap into more" are trademarks of Nifi Ltd. The Service, its design, software, and content (other than Your Content) are owned by Nifi Ltd or its licensors and protected by intellectual property law.
We grant you a limited, non-exclusive, non-transferable licence to use the Service for its intended purpose in accordance with these Terms. You don't get any other rights.
The Service relies on third parties including Clerk (authentication), Vercel (hosting and analytics), Upstash (tag storage), Google (waitlist email and business email), and Resend (transactional email). Their terms and privacy notices apply when their services touch your data. See our Privacy Policy for the full list and how transfers outside the UK are protected.
You can stop using the Service or close your account at any time from the account settings page or by emailing us.
We may suspend or terminate your account, or block individual tags, if we reasonably believe you have breached these Terms, if continued provision of the Service would expose us to legal risk, or if we discontinue the Service. Where it's practical and lawful, we'll give you notice and a chance to fix the problem first.
On termination, sections that by their nature should survive (including intellectual property, disclaimers, limitation of liability, indemnity, and governing law) continue to apply.
The Service is provided "as is" and "as available". To the fullest extent permitted by law, and except as required by the Consumer Rights Act 2015 for consumers, we make no warranties or representations about the Service — including that it will be uninterrupted, error-free, or fit for a particular purpose.
For users without cloud key sync, we cannot recover content if you lose the tag URL or encryption key. Keep your management links safe. For signed-in users with cloud key sync enabled, contact us at founder@nifinotes.com and we may be able to assist with key recovery.
Nothing in these Terms excludes or limits our liability for:
Subject to the above, to the fullest extent permitted by law we are not liable for:
For consumer users, our total liability for any claim relating to the Service is limited to the greater of (a) the amount you have paid us for the Service in the 12 months before the claim, and (b) £100.
If you use the Service in the course of a business (for example, as a Market Stall owner running Live mode for paying customers), you agree to indemnify Nifi Ltd against any claims, losses, or costs (including reasonable legal fees) arising from your breach of these Terms, your use of Your Content, or your handling of personal data you receive through the Service.
This section does not apply to you if you are a consumer using the Service for personal, non-commercial purposes.
We may change the Service from time to time — adding features, removing features, or adjusting how things work. If a change materially affects your rights or how you use the Service, we'll give reasonable advance notice (for example, by email if you have an account or by a notice on the website).
We may update these Terms. If we make material changes, we'll update the "last updated" date at the top of this page and, where reasonable, notify you by email. Continued use of the Service after the update means you accept the new Terms. If you don't accept them, you can close your account.
These Terms and any dispute arising out of them are governed by the laws of England and Wales. The courts of England and Wales have non-exclusive jurisdiction, except that consumers resident in another part of the UK may bring proceedings in their local courts.
Before starting a formal dispute, please contact us at founder@nifinotes.com so we can try to resolve it.
