1. About these terms

These terms apply to everyone who uses Cognitive Lab. By using the site you agree to them; if you don't agree, please don't use it. We may change these terms from time to time, and the date at the top shows when they last changed.

2. Free to use

Cognitive Lab is free to use. If paid features are ever offered, their price and terms will be shown clearly before you pay, and nothing will be charged without your agreement. Nothing in these terms takes away rights you have under the consumer laws where you live.

3. Your data stays on your device

The site saves your profiles, sessions, journal and settings on your own device, not on our servers. If you clear your browser's data or change device, that information can be lost. Use Backup on the site to save a copy you keep yourself. See the Privacy Policy for details.

4. Using the site properly

You agree not to:

• copy, sell, rent, share or redistribute the site or any part of it, including its code, text, design, images, sounds or voices, except as the law allows;
• build or publish a copy or clone of the site, or of its exercises' design, screens or content;
• remove copyright notices, or present the site or its content as your own;
• use the site for anything unlawful, or in a way that could harm it or other people.

5. Our copyright

Cognitive Lab and everything on it, including the code, text, the design of the exercises and screens, images, sounds and voices made for it, belongs to us or to the people who licensed it to us, and is protected by copyright and other laws. You may use the site for your own training while you follow these terms. Nothing else is licensed to you. Training methods and exercise types described in published research belong to no one; our own versions of them, and everything we made, do. See Copyright and Takedowns.

6. Not medical advice; results vary

Cognitive Lab is for training and general interest. It is not a medical device, and it doesn't diagnose, treat, cure or prevent any condition. Scores and charts show how you did on the site; they are not a medical or psychological assessment. Research summaries and guides are for general information. Results vary and aren't guaranteed. If you have concerns about your health, memory or attention, speak to a qualified professional. Please read Health and Safety before you play.

7. Availability and changes

The site is provided free and "as is". We work to keep it running and its content accurate, but we can't promise it will always be available, error-free or unchanged. We may change, add or remove features at any time.

8. Our responsibility to you

• Nothing in these terms limits liability that cannot be limited by law, such as for death or personal injury caused by negligence, or for fraud.
• As far as the law allows, we're not responsible for indirect loss, for business losses (the site is for personal use), or for data lost because it was only kept on your device and not backed up.

9. Ending your use

You can stop using the site at any time. We may block access for anyone who breaks these terms, for example by copying or redistributing the site.

10. Other important terms

• If part of these terms can't be enforced, the rest still applies.
• If we don't enforce a term straight away, we can still enforce it later.
• These terms are governed by the law of the place where Cognitive Lab is run. This doesn't take away any protection you have under the mandatory laws of the country where you live.

11. Contact

Questions: use the Contact us page.

1. The short version

Cognitive Lab keeps your training data on your own device. There are no accounts, no advertising, no tracking, and we don't sell or share your data.

2. What stays on your device

The site saves these in your browser's storage on your device only:

• profiles you create (names and avatars you choose);
• your sessions, scores, levels and progress;
• your journal entries and check-ins (for example sleep, mood and notes you type);
• your settings, and any images or sounds you add to custom exercises.

We can't see any of it. It is never sent to us. Backups you export are files you keep; we never receive them unless you choose to send one to us.

The journal can hold information about your sleep, mood or wellbeing. That stays on your device too; think about who else uses your device before you write anything private.

3. What is processed when you visit

• Our website host processes your device's IP address and basic request details (such as browser type and the page asked for) to deliver the site and keep it secure. These logs are kept by the host for a short time.
• The downloadable version of the site loads its font from an online font service, which receives your IP address when the font is fetched. The website serves its own fonts.
• We don't use advertising, analytics or tracking cookies. The site's own storage is used only to make it work.

4. If you contact us

If you message us through the Contact us page, we use your details and message only to reply, and keep them for up to 2 years after our last contact. Our community chat is run by a third-party service under its own privacy policy.

5. Your rights

Depending on where you live, you may have the right to ask for a copy of your personal data, to correct it, to delete it, and to object to how it's used. Most of your data never reaches us, so you can see, export and delete it yourself on the site (Settings, or your browser's data settings). For anything else, use the Contact us page. You can also complain to the data protection authority where you live.

6. Children

Cognitive Lab is suitable for all ages. It doesn't collect personal data from anyone, including children: everything stays on the device. Our community chat is run by a third-party service with its own minimum age.

7. Changes

If we change how we handle data (for example by adding syncing across devices or anonymous usage counts), we'll update this policy before the change, and ask for your consent where the law requires it.

Our copyright

Cognitive Lab, including its code, text, the design of its exercises and screens, images, sounds and voices made for it, is protected by copyright. Copyright © 2026 Cognitive Lab. All rights reserved. Copying, reposting, reselling, cloning or redistributing any part of it without our written permission is not allowed. We enforce our rights, including by sending takedown notices to hosts, app stores and other platforms, and by legal action where needed.

If you'd like to use something from the site (for example a quote or screenshot in a review, article or teaching), you may already be allowed to under fair dealing or fair use; for anything more, ask us through the Contact us page.

Reporting content on our site that you own

We respect other people's rights. If you believe something on this site infringes your copyright, send us a notice through the Contact us page with:

1. your name and contact details;
2. a description of the work you say is infringed;
3. where it appears on our site (a link or a clear description);
4. a statement that you believe in good faith the use isn't authorised by you, your agent or the law;
5. a statement that the information in your notice is accurate and that you are the owner or authorised to act for the owner;
6. your physical or electronic signature.

We'll review it promptly, remove or disable the material if appropriate, and let you know what we've done. Notices that are knowingly false can make the sender liable for damages.

Photosensitivity

Some exercises show flashing, flickering or fast-moving images and patterns (for example Field of View, MDT and moving targets). A small number of people may have seizures or other reactions when exposed to these, even with no history of epilepsy. If you or anyone in your family has had seizures or epilepsy, speak to a doctor before playing. Stop immediately and seek medical advice if you notice dizziness, blurred vision, eye or muscle twitching, loss of awareness, disorientation or any involuntary movement. Turning on Reduce motion in Display & sound tones down some animations.

Not medical advice

Cognitive Lab is for training and general interest. It is not a medical device and does not diagnose, treat or prevent any condition. If you're worried about your memory, attention or health, talk to a qualified professional.
