Our website

Throughout our website and the Libraro Platform we may link to other websites owned and operated by certain trusted third parties to provide other products and services to you. These other third party websites may also use cookies or similar technologies in accordance with their own separate policies. For privacy information relating to these other third party websites, please consult their policies as appropriate.

What are cookies

A cookie is a small text file which is placed onto your device (e.g. computer, smartphone or other electronic device) when you use our website. Similar technologies include SDKs, pixels, tags, local storage, device identifiers, and other technologies that store or access information on your device or browser.

These help us recognise your device so that you remain logged into the service and help us to ensure the website and platform services are functioning correctly.

For example, we may monitor how many times you visit the website. This information helps us to understand our users and optimise our services for them. Some of this data will be aggregated or statistical, which means that we will not be able to identify you individually.

Why we use cookies

We use cookies for the following purposes:

Strictly necessary: To make the website and platform work, enable core features such as page navigation, security, user authentication (including email login), and to allow you to comment, like, share and access your account. These are essential and do not require consent.
Preferences (functional): To remember your settings and choices (such as language, cookie preferences, and display options).
Analytics and performance: To understand how our website and platform are used, measure performance, and improve our services (for example, page views, feature usage, error diagnostics).
Advertising and marketing: To deliver and measure advertising, including interest‑based or cross‑site advertising where enabled, and to understand the effectiveness of marketing campaigns.
Security and fraud prevention: To help detect and prevent fraud, abuse, or security incidents, and to protect the integrity of our platform and blockchain‑connected functionality.

Your consent is the legal basis for our use of non‑essential cookies (such as preferences, analytics and advertising cookies) under the UK GDPR and EU GDPR.

Where these cookies or similar technologies involve the processing of personal data, such processing is carried out in accordance with our Privacy Policy and applicable data protection laws.

For further information on cookies generally, including how to control and manage them, visit the guidance on cookies published by the UK Information Commissioner’s Office, or www.allaboutcookies.org.

You also have the right to lodge a complaint with your local data protection authority (for example, the Information Commissioner’s Office in the UK or the competent authority in your EU Member State) if you believe your rights have been infringed.

California (CCPA / CPRA) and other US privacy laws

If you are a resident of California, the California Consumer Privacy Act (as amended by the CPRA) gives you additional rights in relation to personal information collected via cookies and similar technologies.

Where cookies or similar technologies involve “personal information” and this information is “sold” or “shared” under the CCPA/CPRA (for example, in connection with certain advertising technologies), we will:

Disclose the categories of personal information collected via cookies, the purposes for which they are used, and the categories of third parties to whom they are disclosed, sold, or shared, in our Privacy Policy and/or this Cookies Policy.
Provide a clear and accessible “Do Not Sell or Share My Personal Information” mechanism (for example, via a link in the website footer or within the cookie banner), allowing California residents to opt out of the sale or sharing of their personal information.
Honour browser‑ or device‑based Global Privacy Control (GPC) signals, where required, as an opt‑out request.

We may also apply similar opt‑out mechanisms to residents of other US states that have comparable privacy laws, where appropriate.

Consent to use cookies and changing settings

Generally we will ask for your consent to place cookies or other similar technologies on your device, except where they are essential for us to provide you with a service that you have requested (e.g. allowing you to login and use the service).

You can withdraw any consent to the use of cookies or manage any other cookie preferences by clicking on the cookie link at the bottom of the landing page or through your browser. You can then update your consents. It may be necessary to refresh the page for the updated settings to take effect.

Cookies and blockchain‑related features

Maintain sessions or security tokens required for blockchain interactions executed via the Libraro platform.
Measure usage of blockchain‑related features and improve their performance.

While blockchain records are outside of your device, the technologies used to interact with those features (such as wallet integrations, SDKs or session tokens) may rely on cookies or similar storage on your device, which are handled in accordance with this Cookies Policy and our Privacy Policy.
