Privacy & cookies
How we handle data on veridexalethia.com and which cookies we use. Last updated: 19 October 2026.
The short version
We do not sell or rent your data, we do not run ads, and we do not track you across sites. We always store essential preferences (language, theme and your cookie choice). If you accept analytics cookies, we use Google Analytics to measure how the site is used; it does not load until you consent, and you can withdraw at any time.
Who is responsible
The controller of the personal data described on this page is VERIDEX Alethia Labs Ltd, company number 17249873, registered office 71-75 Shelton Street, Covent Garden, London, United Kingdom, WC2H 9JQ ("VERIDEX", "we"). VERIDEX is a trading name of VERIDEX Alethia Labs Ltd. For any privacy query or to exercise your rights, contact us via the contact page.
Providing your name and email for contact or access requests is voluntary; if you do not provide them, we may be unable to respond to or assess your request. We do not use automated decision-making or profiling on this website.
What we process, why, and our legal basis
- Site preferences: language, theme and your cookie choice, stored in your own browser (not sent to any server). Basis: legitimate interest in providing a functional site / strictly necessary cookies.
- Contact and access requests: the details you submit (such as name and email) so we can reply or assess a possible engagement. Basis: your consent and/or steps taken at your request prior to a contract.
- Hosting technical logs: our provider (Cloudflare) may process data such as IP address and user agent for security, abuse prevention and delivery. Basis: legitimate interest in the security and operation of the service.
- Analytics (optional): Google Analytics 4, provided by Google Ireland Limited. Only if you accept it, it records the pages you visit, how you reached the site, your approximate location (country and city, derived from your IP address, which Google Analytics 4 does not store), device and browser type, and how you interact with the site, linked to a random identifier stored in the _ga cookies. Google signals and ad personalisation are turned off. Basis: consent.

How long we keep it
Site preferences remain in your browser until you clear them. Messages you send us are kept only as long as needed to handle your request and meet legal obligations, then deleted or anonymised. Google Analytics data is kept for the retention period set in our Google Analytics account, at most 14 months; the _ga cookies expire after 2 years or when you withdraw consent. Hosting logs are processed by Cloudflare as our hosting provider and retained under Cloudflare's own retention policy and our data processing agreement with it; we do not set that period. Logs may be kept longer where needed for a security investigation or a legal obligation. Details available on request.
Who we share it with
We do not sell or rent personal data, and we do not share it with advertising networks. We use a small number of providers that act as processors on our behalf, primarily: Cloudflare (site hosting and delivery), our email provider (to reply to your messages) and Google (site analytics, only if you accept analytics cookies). We may also disclose data where required by law.
International transfers
Cloudflare may process data in the US and other countries. For transfers from the UK and the EEA to the US, Cloudflare is certified under the EU-US Data Privacy Framework and the UK extension to it; where a transfer is restricted, our agreement with Cloudflare applies the EU Standard Contractual Clauses, as amended by the UK Addendum for UK-protected data; details are available on request via the contact page.
If you accept analytics, Google may process Google Analytics data in the US. Google LLC is certified under the EU-US Data Privacy Framework and the UK extension to it, and Google's data processing terms include the EU Standard Contractual Clauses for restricted transfers.
Your rights
Depending on your jurisdiction (for example, the EU/UK GDPR), you may have the right to access your data, rectify it, erase it, restrict or object to its processing, data portability, and to withdraw consent at any time without affecting prior lawful processing. You may also lodge a complaint with your data protection supervisory authority.
To exercise any of these rights, contact us via the contact page. We will respond within the timeframes required by applicable law.
You can also delete or block cookies from your browser settings. Blocking essential cookies may affect preferences such as language and theme.
Children
This site is aimed at professionals and institutions, not children, and we do not knowingly collect data from anyone under 16.
Blockchain & anchoring
Cryptographic anchoring currently runs on Arbitrum Sepolia (testnet). There is no publicly committed date for moving to a mainnet. PDF certificates and the Evidence Continuity Index are independent of the blockchain network used. Anchors are designed not to include document content. They record cryptographic hashes and related transaction metadata. In most cases these hashes are not intended to identify individuals, but hashes may be treated as personal data where they can be linked with other information or where the underlying document is guessable. We therefore treat anchoring metadata as privacy-relevant and minimise what is anchored.
Changes to this policy
We may update this policy as the product evolves or legal requirements change. The current version, with its update date, will always be posted here. Last updated: 19 October 2026.
