The short version, and the long one.

NeuroLens is a reading application, free for personal or professional reading. You need to be old enough to agree to terms where you live; if you are not, an adult should agree for you.

Files you open are read inside your browser and kept on your device. They stay there until you choose to upload them to your account; NeuroLens asks before it sends anything, and declining leaves everything where it is.

Uploaded or not, they remain yours. You keep every right you already had in them, we acquire none, we do not read them, and we do not use them to train anything. What an account changes is reach — the same book, on whatever you next read on — not ownership.

A copy stays on the device either way, which is what lets you read offline, so browser storage limits still apply and clearing browser data still clears that copy. Anything in your account survives it. Your account exports everything as one file, and erases everything on request.

Only upload documents you own or are otherwise permitted to read and copy, and do not use NeuroLens to store or share anything unlawful. You keep every right you already had in your files; we acquire none.

Everything you bring into NeuroLens — a document, a note, a highlight, a bookmark — is yours. It is also yours to answer for.

Nothing you open here is reviewed, moderated or approved by us. What you keep on your device never reaches us at all; what you upload is stored for you and read by nobody. Nothing being blocked is not the same as something being checked. No person looks at what you open, and no system vets it.

So having the right to read, copy and adapt what you bring in is on you, as is what you do with it afterwards — including anything you export and pass on to somebody else. If a third party brings a claim against us because of material you brought in or shared, you cover what it reasonably costs us to deal with. That does not apply where the claim is our fault rather than yours, and it takes away none of the rights the law gives you as a consumer.

We cannot take a file off your device — only you can do that, and the account page erases what you have uploaded. Where something is being used unlawfully, that sits between you and whoever holds the rights; where it sits in an account and we are told, support is how to reach us, and we will act on it.

Reading requires an account, so that your books and highlights can follow you between devices. Signing in uses Google, so there is no password for us to hold. You are responsible for the security of the account you sign in with, and can stop using it at any time — the account page erases everything we hold.

A few features fetch from third parties when you ask: Bible passages, library records, poems and definitions. Those requests are governed by each service's own terms; the privacy page names them.

NeuroLens is designed with dyslexia, ADHD and cognitive fatigue in mind, and may make reading easier. It is not a medical device, does not diagnose anything, and is no substitute for a professional. Nothing it shows you — including what adaptive mode notices — is a clinical finding.

The app comes without warranties of any kind. We do not promise it will always be available, free of faults, or read every file correctly. As far as the law allows, we are not liable for loss from using it — including documents or notes stored in your browser.

Nothing here limits liability the law does not allow to be limited, and consumer rights are unaffected.

Talk to us first. Nearly everything is a misunderstanding or a bug. Send support a description of the problem and what you would like done about it, and give us 60 days to put it right. Most of this section never comes up.

Then arbitration, not a courtroom. If 60 days pass without resolution, a dispute between us is settled by binding arbitration before the Lagos Chamber of Commerce International Arbitration Centre (LACIAC), under the LACIAC Arbitration Rules, seated in Lagos and conducted under the Arbitration and Mediation Act 2023, by a single arbitrator and in English. Arbitration is usually faster and cheaper than a court case, and the arbitrator can award the same remedies a court could — but it is more private, an award can only be set aside on the narrow grounds that Act allows, and you are giving up your day in court. That is why it is named in the summary at the top of this page rather than left down here to be discovered.

You can opt out, and it costs you nothing. Within 30 days of first accepting these terms, email support with the words arbitration opt-out and the address you use here. That is the whole process. Nothing else in these terms changes, and we will not treat you differently for it — you simply keep the courts of Lagos State instead.

One person at a time. Claims are brought individually: not as a class action, not combined with anybody else's claim, and not by a representative acting for a group. If that restriction turns out to be unenforceable for a particular claim, then that claim belongs in court rather than in arbitration, and the rest of this section still stands.

Two things either of us can still take to court. A claim small enough for a small claims court can go there instead — in Lagos that is the Small Claims Court of the Magistrates' Court, which is designed to be used without a lawyer — and either side can ask a court to stop misuse of intellectual property without waiting on arbitration.

Where local law says otherwise, local law wins. Plenty of places — the EU and the UK among them — do not let a consumer be required to arbitrate in advance. If you live somewhere like that, this section takes nothing away from you: you keep your local courts, and your mandatory consumer protections apply in full. Readers in Nigeria keep their rights under the Federal Competition and Consumer Protection Act 2018, including the right to complain to the FCCPC, and nothing here is an attempt to sign those away. These terms are otherwise governed by the law of Nigeria.

These terms may change as the app does; the date at the top says when. A change that materially reduces your rights will be announced in the app, not slipped in quietly.

Stop using NeuroLens whenever you like — erasing your data from the account page is immediate and complete on that device. Access may be suspended where the app is used unlawfully.

Questions about these terms go through support.

Written in plain language to describe how the app behaves. Not reviewed by a lawyer, and not legal advice. The arbitration section in particular decides where and how a dispute is heard, and it is unfinished until the bracketed blanks above are filled in and a lawyer has read it.
