How we protect your data
Ndiversity is a self-reflection tool developed with a certified psychotherapist. It is not a medical diagnosis. Here is exactly what data we handle and why. Questions: nidana.ndiversity@gmail.com
Data controller: Ndiversity UG, Skalitzer Str. 68, 10997 Berlin, Germany
The following data is collected and connected to your account:
Contact info
- Email address, first and last name
- Used for: creating your account, signing in (we email you a sign-in code), and account emails. Never for advertising.
Profile
- The name you go by, your age range and your gender, all self-reported
- Used for: confirming you are 18 or older, and how the assistant addresses you. Your name, age range and gender are also part of what the assistant sees about you. If you ask the assistant in a chat to call you something else, it remembers that name in the notes it keeps about you.
Health-related info
- Your self-assessment answers and your neurodiversity profile
- What you tell us before signing up: whether you have a diagnosis, identify as neurodivergent yourself or aren't sure, and the neurotype you name
- Used for: generating your personal results and choosing the questions that fit you. This is sensitive data. We only process it with your explicit consent, and it is stored in the EU. Your neurodiversity profile and what you tell us before signing up (not your answers) are also part of what the assistant sees about you.
Messages
- Your AI chat conversations, plus the short note each chat leaves for your next one, the personal portrait we write from them, and the working notes of the AI pass that rewrites the portrait: which chats it re-read, a summary of its reasoning, and what it changed and why
- When a chat that started with your portrait ends, the AI also writes a short note on how the chat used it: a rating from 1 to 5, which parts of the portrait it drew on, what it was missing and what was in its way
- Used for: running the chat and giving it memory across sessions. The portrait is a written profile of you, produced by AI from your chats — what helps you, what to avoid, what is still open. It is not shown to you in the app; ask us if you want to see yours. The notes on how a chat used your portrait help us learn how to write better portraits.
Voice dictation
- If you dictate instead of typing, the recording goes from your browser to our servers in the EU (Ireland) and from there to a speech-to-text model, and the transcript lands in the message box, where you can edit or delete it before sending
- Used for: turning speech into text. We never store the audio. Unlike the chat, dictation runs without a promise that nothing is kept: the speech-to-text provider (OpenAI) may keep the recording for a limited time under its own terms. We store a record of each dictation, linked to its chat but without the audio or the text, to track what it costs us.
Session details
- The approximate location your internet connection suggests (city and country), your time zone, and whether you are on a phone, tablet or desktop
- Used for: letting the assistant know roughly where and when you are. Rounded coordinates also go to a weather service, so it can mention the weather where you are. Saved with the chat.
Visit info
- The device category you use and, if you arrive via a campaign link, its campaign parameters
- Used for: understanding how people find and start our self-assessments. Collected under a random session id before you have an account, and connected to your account once you sign up.
N Nest waitlist
- That you asked to join the N Nest or the N Circle waitlist
- Used for: getting back to you when group sessions open, and counting how many people are waiting.
Who at Ndiversity can see this
- Our founders can open your chats, the notes they leave for your next chat, your portrait, the notes of the AI pass that maintains it and the notes on how each chat used it in an internal review tool
- If the AI spots a possible risk to your safety in a chat, it writes a short note our founders see, with your name and email
- Used for: checking the quality of the assistant, and being able to react when someone may be in danger. Nobody else has access.
Some technical data is collected without being connected to your personal profile:
Diagnostics
- Server logs, including IP addresses
- Used for: security and troubleshooting.
Usage data
- Aggregate technical metrics (performance, error rates)
- Used for: keeping the service running reliably. Not tied to individual profiles.
- No advertising or tracking cookies — only a login session cookie
- No sharing your data with advertisers or ad networks
- No tracking you across other apps or websites
- No storing your voice recordings
- No training AI models on your data
- No users under 18
- Your assessment data, profile, chats with their notes, and portrait are stored in the European Union (Ireland)
- Our servers, hosted by Vercel, handle your requests in the European Union (Frankfurt)
- Everything we send to an AI model goes through the Vercel AI Gateway, labelled with an internal ID, never with your name or email. The gateway keeps nothing and passes each request on to a provider of the model: its maker, or a cloud that hosts the same model (for Anthropic's models, for example, Amazon Web Services). Today these are Anthropic models for the chat and your portrait, OpenAI models for dictation and for searching our knowledge base, and Perplexity when the assistant searches the web
- For the chat, your portrait and searches of our knowledge base, we ask the gateway to use only providers that have agreed to keep nothing of what we send. Dictation and web search can't run that way today: OpenAI (dictation) and Perplexity (web search) may keep what they receive for a limited time under their own terms. The assistant writes each web search itself, and it may include details from your chat
- Our sign-in provider (Clerk) and our AI providers (Anthropic, OpenAI, Perplexity) process limited data in the US under EU-approved safeguards
- The weather service (Open-Meteo) receives rounded coordinates only — no account, no name, nothing else about you
- Delete your account and everything we hold about you: write to nidana.ndiversity@gmail.com and we erase it. There is no delete button in the app yet.
- Export a copy of your data: ask us and we send it to you
- Withdraw consent or ask us anything: nidana.ndiversity@gmail.com — we reply within one month
- You can also complain to your local data protection authority
