Terms of Service

Agreeing to these terms

By creating an account, installing the extension, or otherwise using the Service, you agree to these Terms of Service, our Privacy Policy, and our Refund Policy. If you do not agree, do not use the Service. If you use Synapse on behalf of an organisation, you confirm that you are authorised to accept these terms for it, and “you” includes that organisation.

Who we are

Synapse is operated by Akapo Abdul-Raheem (“Synapse”, “we”, “us”). The website at usesynapse.cv, the Synapse dashboard, and the Synapse browser extension are together called the “Service”.

The Service

Synapse helps you read and understand content on the web. Depending on your plan, you can highlight or circle content to have it explained, reformat pages into a structure that suits you, open PDFs in the Synapse viewer, and keep a reading profile that adapts to your feedback. The Service uses third-party AI models to produce explanations and reformatted content.

Synapse is currently available for Google Chrome on desktop. Features differ between plans, as described on our pricing section at the time you subscribe.

Who can use Synapse

You must be at least 13 years old to use Synapse. If you are under 18, or under the age of legal majority where you live, you may use Synapse only with the permission of a parent or guardian, who agrees to these terms on your behalf and is responsible for your use, including any payments.

Your account

• Give accurate information when you sign up, and keep your email address up to date.
• Keep your password secure and do not share your account. You are responsible for activity on your account unless it results from our failure to keep the Service secure.
• Tell us straight away at help@support.usesynapse.cv if you think someone else has access to your account.
• One person per account. Accounts may not be shared, resold, or transferred.

You can delete your account at any time from your profile page. Deleting your account cancels any active subscription immediately and permanently deletes your data, as described in the Privacy Policy.

Plans, trials, and payment

Free and paid plans

Synapse offers a free plan and paid subscription plans. Each plan includes the features and usage allowances shown when you subscribe. Usage allowances reset each period and unused allowance does not carry over.

Free trial

Paid plans start with a 7-day free trial. You need to add a payment method to start it. If you do not cancel before the trial ends, your subscription starts automatically and you are charged for the first billing period. You can only have one free trial.

Billing and automatic renewal

Subscriptions are billed in advance, monthly or annually depending on the option you choose, and renew automatically at the end of each period at the then-current price until you cancel. Prices are shown and charged in Nigerian naira unless stated otherwise. If your card is not in naira, your bank may charge currency conversion or international transaction fees, which are your responsibility. Prices may not include taxes, which we will add where the law requires.

Payments are processed by our payment provider, Paystack, under its own terms. You authorise us and Paystack to charge your payment method for each billing period, and for any plan change you make. When you start a subscription, Paystack also makes a small check on your card, which is refunded straight away.

Changing plans

You can upgrade or downgrade at any time from your subscription page. When you change plans, the price difference for the rest of the current period is charged or refunded straight away.

Cancelling

You can cancel at any time from your subscription page. Cancelling stops future renewals. You keep access to your paid plan until the end of the period you have paid for, after which your account moves to the free plan. Refunds are covered by our Refund Policy.

Price changes

We may change our prices. We will tell you at least 30 days before a price change affects your subscription, and the new price applies from your next renewal after that notice. If you do not agree, you can cancel before the change takes effect.

Failed payments

If a payment fails, we may retry it and ask you to update your payment method. If payment is still not received, we may move your account to the free plan.

Discounts

Student and regional pricing is offered at our discretion, may require proof of eligibility, and may be withdrawn if eligibility ends or the proof provided was not genuine.

Acceptable use

You agree not to:

• use the Service for anything illegal, or to infringe anyone’s rights, including copyright and privacy;
• submit content you do not have the right to use, or other people’s personal information without a lawful reason;
• try to get around plan limits, usage allowances, or security measures, including by creating multiple accounts or free trials;
• access the Service through automated means such as bots, scripts, or scrapers, or use it to build a competing product;
• copy, modify, decompile, or reverse engineer the Service, its extension, or its software, except where the law expressly allows it;
• resell, sublicense, or provide the Service to others as part of your own service;
• interfere with or overload the Service, or try to gain unauthorised access to it, its systems, or other users’ accounts;
• use the Service to create harmful, abusive, or deceptive content, or in breach of the usage policies of the AI providers we rely on.

Your content

“Your content” means the text, images, and other material you send to Synapse, such as passages you highlight, areas you circle, pages you reformat, notes, and feedback. You keep all rights you have in your content. You give us a worldwide, non-exclusive, royalty-free licence to use, process, and store your content only as needed to provide, secure, and improve the Service for you, including sending it to our AI providers. This licence ends when your content is deleted, except for copies we must keep by law.

You are responsible for your content and for making sure you are allowed to submit it. Explanations and reformatted content produced for you are yours to use, subject to any rights others have in the original material and to applicable law.

AI output and health

Explanations and reformatted content are generated by AI and can be incomplete, inaccurate, or out of date. Check anything important against the original source. Synapse is a reading aid. It is not medical, psychological, legal, financial, or other professional advice.

Synapse is designed to support people with ADHD, dyslexia, autism, and others who find dense content hard to read, but it is not a medical device. It does not diagnose, treat, or monitor any condition, and your reading profile is not a clinical assessment.

Third-party sites and services

Synapse works on websites and documents owned by others. We do not control and are not responsible for them, and using Synapse on a site does not give you any extra rights to its content. The Service relies on third-party providers, such as AI model providers, Google sign-in, and Paystack, whose own terms may also apply to you.

Our intellectual property

The Service, including its software, extension, design, text, graphics, and the Synapse name and logo, is owned by us or our licensors and protected by intellectual property laws. Subject to these terms, we give you a personal, non-exclusive, non-transferable, revocable licence to use the Service for your own personal or internal purposes. All rights not expressly granted are reserved.

Feedback

If you send us suggestions or ideas, we may use them without any obligation to you. This does not cover your content or the feedback ratings you give on results, which are handled under the Privacy Policy.

Changes to the Service

We are constantly improving Synapse and may add, change, or remove features. The extension may update automatically. If we remove a feature that is a material part of a paid plan you are subscribed to, we will tell you in advance where we reasonably can, and you may cancel and request a refund for the unused part of your current period.

Suspension and termination

We may suspend or close your account, or limit your use of the Service, if you seriously or repeatedly break these terms, if your use creates a risk or legal exposure for us or others, if payment fails, or if the law requires it. Where reasonable, we will tell you why and give you a chance to fix the problem first. If we close your account without cause, we will refund the unused part of any prepaid period.

You can stop using the Service and delete your account at any time. Sections that by their nature should continue after termination, including those on content, disclaimers, liability, indemnity, and governing law, continue to apply.

Disclaimers

To the fullest extent allowed by law, the Service is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not promise that the Service will be uninterrupted, error-free, or work on every website or document. Nothing in these terms limits rights you have under consumer protection laws that cannot be excluded.

Limitation of liability

To the fullest extent allowed by law:

• we are not liable for indirect, incidental, special, consequential, or punitive damages, or for loss of profits, revenue, data, or goodwill, arising from your use of the Service;
• our total liability for any claim relating to the Service is limited to the greater of the amount you paid us in the 12 months before the claim arose, or US$50.

These limits do not apply to liability that cannot be limited by law, such as for death or personal injury caused by negligence, or for fraud.

Indemnity

To the extent allowed by law, you agree to compensate us for claims, losses, and reasonable costs, including legal fees, arising from content you submit or your breach of these terms. This does not apply if you are using the Service as a consumer in a country where such terms are not permitted.

Governing law and disputes

These terms are governed by the laws of the Federal Republic of Nigeria. Before starting any formal dispute, please email us at help@support.usesynapse.cv so we can try to resolve it informally. If we cannot resolve it within 30 days, either of us may bring the dispute before the courts of Lagos State, Nigeria.

If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you may bring proceedings in your local courts where those laws allow it.

Changes to these terms

We may update these terms. The effective date at the top shows when they last changed. If a change is material, we will tell you by email or in the Service at least 30 days before it takes effect. If you keep using Synapse after that, you accept the new terms. If you do not agree, you can cancel and delete your account before they take effect.

General

• These terms, together with the Privacy Policy and Refund Policy, are the whole agreement between you and us about the Service.
• If any part of these terms is found unenforceable, the rest stays in effect.
• If we do not enforce a right straight away, we have not given it up.
• You may not transfer your rights under these terms. We may transfer ours, for example if Synapse is registered as a company or sold, and will tell you if that happens.
• We are not responsible for delays or failures caused by events outside our reasonable control, such as outages at our providers, power or network failures, or natural disasters.
