NeuroDynamicYour privacy, in plain English.
The short version: no ads, no tracking cookies, and we don’t keep what you say. Below is exactly what we do keep, why, and for how long.
Last updated: October 2026. If we change anything important, we’ll say so here and, if you have an account, by email.
The short version
- One cookie, only when you sign in. It keeps you signed in. Nothing else.
- No tracking, no ads. Nothing here follows you around the web, and we don’t sell data.
- What you say isn’t kept. No recordings or transcripts on our server. Never used to train AI.
- You’re in charge. Ask to see or delete your information at any time.
Cookies
We use one cookie, and only when you sign in. It’s a secure, HTTP-only cookie that keeps you signed in for up to seven days, so you don’t have to log in on every page. Signing out ends it.
We don’t use advertising, tracking or analytics cookies, so nothing here follows you around the web. That’s why there’s no cookie banner: there’s nothing to agree to.
Saved in your browser, not on our server
A few choices are kept in your own browser so the site remembers them. They never leave your device, and clearing your browser data removes them. It doesn’t delete your account or any email sign-up.
- Your Display choices: colours, text size, spacing, font, reading ruler, reduce movement and read-aloud speed.
- Your saved guides, your progress through guides, and your usefulness reactions.
- Whether you’ve seen our note about cookies.
- Notes in the planning activity, kept only in the current tab.
How we count visits
We count page visits, clicks and time on pages on our own server, so we can see which pages help and which need work. We don’t use Google Analytics or any advertising tracker, and we don’t build a profile of you.
Cloudflare sits in front of our server to provide the secure connection and block attacks. To do that it sees connection details, such as your IP address and the page you asked for, much as any network your traffic passes through does. It doesn’t set cookies on this site, and Cloudflare’s privacy policy says it doesn’t sell this data or use it for advertising.
Your account
A free account lets you download the apps and use the free hosted allowance. It doesn’t need payment details. It does need an email address that you confirm: that keeps the free allowance fair, one per person, and stops the service being misused by people creating lots of accounts.
- What we keep: your username, your email address and whether you’ve confirmed it, a scrambled (hashed) copy of your password and recovery code, when you joined, your active sign-ins, and which apps you can download. Passwords, sign-in tokens and recovery codes are never stored in readable form.
- Signing out ends that sign-in. Using your recovery code ends all your sign-ins and gives you a new code.
- How long: while your account is active. If you don’t sign in for 6 months, we delete the account. We’ll email you a month before, so you can keep it by signing in.
- Age: accounts are for people aged 16 and over.
Hosted speech and AI
The promises in this section describe the desktop app’s hosted speech features. Paid agent APIs on x402 are separate services with their own privacy notice.
The website itself never uses your microphone. When you dictate with LexVoca, your speech goes to the service you choose in the app: a model on your PC, your own server, or ours.
If you use ours, it’s processed on our own servers, including the AI features: your words are never sent to an outside AI company. And we don’t keep recordings or transcripts. Your speech and text are processed, and the result can sit in temporary memory for up to ten minutes, or until your app confirms it has it. LexVoca’s own history stays on your PC, under your control. Nothing you say is used to train AI.
To run the service and your allowance, we keep some numbers about each request, never the words. We also look at them as totals, to see how the service is used overall, what to improve and where it needs to grow. We don’t look at what any one person does, unless we need to look into misuse of the service. We just want to be clear about what’s kept:
Changing your password signs out your connected apps, and your LexVoca account page lets you sign out any device.
Backing up your settings (your choice)
You can choose to back up your LexVoca settings to your account, so you don’t have to set things up again on another computer. That includes things like the words you’ve added to your dictionary and your writing styles. It never includes anything you’ve said or dictated. It’s off unless you switch it on, and you can switch it off and delete the backup at any time.
Read aloud on this site (in Display) uses our natural voice, made on our own servers. The text being read is sent to our server only to make the audio. If our voice isn’t available, you can choose a voice installed on your device instead.
Emails and messages you send us
- Your account email. We use it to confirm your account and to send messages about it, such as security notices and important changes to the service. We don’t send marketing to it, and we never share it.
- App and plan updates. If you ask to hear when an app, or our paid plans, become available, we keep your email address, what you asked about, and when you agreed. We use it only for that news, never a general mailing list. Every email has an unsubscribe link, and the private link shown when you sign up removes you without an account. Unused sign-ups are removed after 12 months.
- Messages through our contact form. We keep your email address, your name if you give it, your message and its topic, only to reply. Messages are deleted 12 months after the conversation ends.
Email addresses are stored privately on our own server. We’ll name our email delivery provider here before we use one.
Security
- We limit repeated sign-in attempts to stop people guessing passwords.
- Security logs record the type of request and whether it worked, never passwords, recovery codes, email addresses or what you typed. Logs are rotated regularly.
Why we’re allowed to use it
The law asks us to say why we can use each kind of information. In short:
We don’t make automated decisions about you that have legal or similar effects. The free allowance is just a usage limit.
Who else is involved
We don’t sell or share your information. We use as few outside services as we can, and each only gets what it needs:
- Cloudflare provides the secure connection and protection from attacks. Browsers may also send network-error reports to Cloudflare to help diagnose connection failures. It’s a US company, so connection details may be handled outside the UK, under approved safeguards.
- An email delivery provider and a payment provider, when we start using them. We’ll name them here first.
Your rights
You can ask us to:
- tell you what we hold about you, and give you a copy
- correct anything that’s wrong
- delete your information or your account
- stop or limit how we use it, or object to how we use it
- give you your information in a form you can take elsewhere
Email [email protected] and include your username if it helps. Never send your password or recovery code. We’ll check it’s your account before changing anything, and reply within a month.
If you’re not happy with how we’ve handled your information, please tell us first. You can also complain to the Information Commissioner’s Office (ICO), the UK’s data protection regulator, at ico.org.uk/make-a-complaint or on 0303 123 1113.
