Privacy Policy
Last updated Jun 26, 2026
Adimen builds privacy-first tools for the AI era. Privacy is not a feature we add on top — it is the reason the products exist. This policy explains what data we do and do not collect, both in our software and on this website.
In short: our products run on your machine and send nothing to us. This website collects only the minimum needed to operate, and we never sell your data.
This policy applies to the Adimen website (adimen.app and its subdomains) and
to the Adimen products — including Velum (browser extension, desktop app,
and command-line tool), and other tools in the Adimen suite.
Our products: local by design
Adimen's tools are built to run fully on your device.
- Velum browser extension detects and masks personal data before it reaches any large language model, then restores it in the reply. All detection runs locally using a model bundled inside the extension. The extension makes no network requests and contains no analytics or telemetry. Your text, your files, and the mapping that re-identifies masked data never leave your browser, and the mapping is cleared when the browser closes.
- Velum desktop and CLI process documents locally in the same way. The desktop app includes an optional, off-by-default local usage log to help you understand your own usage; those logs are written only to your machine and are never transmitted to Adimen.
We do not receive, store, or have any access to the content you process with these tools. There is no account to create and no data to sync.
This website
When you visit adimen.app, we process a limited amount of data to run the site
and respond to enquiries:
Analytics
We use a self-hosted, privacy-friendly analytics tool
(analytics.adimen.app) to understand aggregate traffic — which pages are
viewed and roughly where visitors come from. It does not use tracking
cookies, does not fingerprint you, and does not follow you across other
websites. Data is aggregated and cannot be used to identify you.
Contact form
If you use the contact form, we collect the name, email address, and message you submit so we can reply. Submissions are delivered to our inbox through our email provider (Resend). To prevent spam, the form is protected by Cloudflare Turnstile, a privacy-respecting bot check that does not profile users. We use this information solely to respond to your enquiry and do not add you to any marketing list without your consent.
Server logs
Our hosting provider may keep standard, short-lived technical logs (such as IP address and request time) for security and reliability. These are not used to build profiles of visitors.
What we never do
- We do not sell, rent, or trade your personal data.
- We do not show third-party advertising or embed advertising trackers.
- We do not access the content you process in our local tools.
- We do not use your data to train AI models.
Third parties
We rely on a small number of service providers strictly to operate the website:
- Resend — delivers contact-form emails.
- Cloudflare Turnstile — spam/bot protection on the contact form.
- Our hosting and analytics infrastructure — serves the site and aggregates anonymous traffic statistics.
Each processes data only as needed to provide its service.
Data retention
- Contact-form emails are kept for as long as needed to handle your enquiry and our records of it, then deleted.
- Aggregate analytics contain no personal data and are retained in anonymous form.
- We retain personal data no longer than necessary for the purposes described here.
Your rights
Depending on where you live (for example, under the EU/UK GDPR), you may have the right to access, correct, delete, or restrict processing of your personal data, and to object to processing or request portability. Because our products store no personal data on our side, these rights mainly concern data you have sent us directly, such as a contact-form message. To exercise any of these rights, contact us at the address below.
Children
Our products and website are not directed to children under 16, and we do not knowingly collect personal data from them.
Changes to this policy
We may update this policy as our products and legal obligations evolve. Material changes will be reflected by the "Last updated" date above.
