What is n1lab?
An observation journal for one-person experiments, currently a free beta.
n1lab records the symptoms, foods, protocols, and conditions you choose to track, and shows them back to you across days and weeks. It is beta software run by one person: features will change, occasionally something will break, and fixes ship fast but not instantly.
What is n1lab not?
Medical advice, a medical device, or a substitute for care.
The app records what you record and computes plain summaries of it. It does not diagnose, treat, cure, or prevent anything, and nothing n1lab itself says is a recommendation to start, stop, or change any diet, medication, or treatment. A plan or a change a practitioner writes is theirs, and n1lab shows it to you as theirs. Decisions about your health belong with you and qualified practitioners.
If you are dealing with something urgent, the right tool is emergency services or a clinician — not a journal.
Your account
One person, a real email, a password you protect, and you're 18 or older.
You are responsible for what happens under your sign-in, so keep the credentials to yourself. Accounts are personal — one observer per notebook. We can suspend or close accounts that attack the service or other people's data (see section 06).
Your content
Your readings are yours. We get only the permission needed to run the service for you.
You keep all rights to everything you enter. You grant us the limited licence required to operate the service: storing your entries, backing them up, computing your own summaries from them, and rendering them on your screens; showing them, read-only, to a practitioner you choose to share with, until you stop; and answering a support question you send us, which may mean looking at the part of your record the question is about and, with names and health details removed, using the question to make Help clearer. The last two apply only when you choose to share or to ask. That licence exists so the app can function, and it ends with your account, apart from backups and logs, which age out within 7 days. The privacy page covers who can see what.
If you attach a practitioner's plan or documents, that material is between you and your practitioner — you're responsible for having the right to upload it, and we store and display it to you without republishing it or presenting it as our own guidance.
If you use n1lab as a practitioner
A client's record is theirs. You read it because they chose to share it with you, and only to support them.
- Use what a client shares only to support that client, in the way they asked you to, and in n1lab's own practice tools, such as groups. Keep it confidential, except where the law or your professional obligations require otherwise. What you copy out of n1lab, into your own notes for example, is yours to protect under the privacy law and professional rules that apply to your practice.
- When you use your n1lab access, read a client's record only through n1lab's screens, where each read is written to the client's access log. Don't reach it any other way, for example with scripts or direct requests to the database. A file a client gives you themselves, such as an export, is theirs to share.
- When a client revokes your access, your access through n1lab ends at once, and the point above still holds: don't reach their record any other way. What you already took from it stays under the rules that apply to your practice.
- Invite only someone who has asked you to, is 18 or older, and gave you the address. An invitation to an address with no n1lab account creates an account there.
- Your name and practice must be your own. Don't invite anyone, or accept an invitation, as someone else: n1lab doesn't check them, and clients rely on them.
- A plan change you propose is a suggestion for the client to decide on. Don't create or change a proposal outside n1lab's screens, and keep your note accurate.
- n1lab isn't part of your professional relationship with a client. Nothing it shows you is advice, and your advice is your own.
- If you break this section, we may end your access to n1lab.
This section is new on 30 sep 2026. If you had accepted a client's invitation or invited a client before then, it applies to you 14 days after we email you about it, and not before 14 oct 2026. The privacy page says what n1lab keeps about you as a practitioner.
Acceptable use
Use it lawfully, on your own data or data a client has shared with you, without breaking the instrument.
- Don't probe, bypass, or test the service's security, or try to reach rows you haven't been given access to.
- Don't scrape, resell, or provide automated third-party access to the service.
- Don't upload malware or unlawful content, and don't upload someone else's records as your own.
Reasonable, honest security research reported privately is welcome — write first.
The beta bargain
Free while in beta. Whatever changes, your data stays exportable.
n1lab is free during the beta. Paid plans may come later; if they do, you'll be told clearly before anything costs money, and your existing records will remain yours to export regardless of what you choose. We may add, change, or retire features while the product finds its shape, and we don't promise uninterrupted availability.
If we ever discontinue the service, you'll get reasonable notice and a window to export everything first.
Liability, plainly
The service is provided as-is; your statutory rights are untouched.
We build carefully, but we don't warrant that the app is error-free or that any summary it computes is complete or correct — the readings are inputs you chose, and the arithmetic is an aid to your own judgement. To the extent the law allows, our liability for a problem with the service is limited to resupplying the service.
Nothing in these terms excludes rights that can't be excluded — including the consumer guarantees of the Australian Consumer Law.
Changes, and where these terms live
Governed by the law of New South Wales, Australia. Changes are dated on this page.
When these terms change, the "last reviewed" date above changes with them, and material changes will be flagged to you, in the app or by email, at least 14 days before they apply to you. A change that only covers something you choose to do, such as sharing your record or sending us a question, applies when you do it. Continuing to use n1lab after a change means you accept the updated terms; if you don't, export your data and close the account — no hard feelings, it's your notebook.
