Privacy & cookies
Who: Limitless Mindset Amsterdam, organised by Giovanni Kerkhof, the Netherlands. Contact: hello@limitlessmindsetamsterdam.com.
What we collect: your email address, your first name if you give it, your choices on the form (format, topics, time, language, how you heard about us), whether you ticked the optional newsletter box, and which version of the page you saw. For each first visit that is given a page version, the website also keeps a visit record: a random visitor number, the page version, the date and time, the channel and campaign of the link you followed, whether the page was actually displayed, and the country and network owner the visit came from (for example the name of your internet provider) — not your IP address, which the website does not store. No health information, no phone number, no postal address.
Why, and on what basis: to run the relaunch interest list you asked to join (your consent), to email you about the relaunch (after the welcome email, at most once a week), and — only if you ticked the optional box — the weekly newsletter (separate consent). The visit records and the counts per page version serve a fair test of which invitation works best (my legitimate interest); they hold no name or email address.
Where it is kept: your email and name are encrypted on the website the moment you submit, held encrypted in the website's database (Cloudflare) until my processor collects them — normally within minutes — and then stored only in the list's mailbox on my own mail server, a rented server at Hostinger in Frankfurt, Germany. Cloudflare keeps a restore history of that database for 30 days, so the encrypted copy can remain there for up to 30 days; the mail server keeps no delivery log, and Hostinger's backups of it can hold data for up to about two weeks. Statistics on my computer use a salted one-way code instead of your email. Your details are not sold, not shared with other projects, and not used for advertising.
Who reads what you write: messages sent to hello@limitlessmindsetamsterdam.com are read and handled by an AI assistant (Claude, by Anthropic, a US-based service) that runs this list for me. It answers routine questions and carries out requests such as deleting your details, and it can look up your sign-up record to do so. A copy of every message from a person also goes to my own inbox, and I can step in at any time. What the assistant reads is processed by Anthropic in the US; that transfer is covered by the standard contractual clauses Anthropic relies on.
How long: your sign-up record — at most 12 months after your last confirmation; unconfirmed sign-ups are deleted within 30 days. Copies of your choices without your name or email, and the visit records, are kept for the statistics of this test for at most 12 months.
Deletion & your rights: use the unsubscribe link in any email: your sign-up record (email, name and choices) is removed from the list's mailbox, normally within minutes, and you get one last email. A reply that starts with "delete" works too when it comes from the address you signed up with. After that I keep only a one-way code so you are never emailed again (the form will not re-add that address — write to me if you want to come back), plus the copies without name or email described above. Messages you sent stay in the mailboxes. You can also ask for access, correction or a copy of your details, and you may complain to the Dutch data protection authority (Autoriteit Persoonsgegevens).
Cookies: three first-party cookies — the page version you were shown (so you always see the same one), a random visitor number, and the channel you came from — kept for 180 days; a fourth marks our own test visits. No advertising or cross-site tracking cookies, no third-party scripts.
AI: texts on this site are prepared with AI assistance and published by the organiser. What you enter in the form is processed by my own scripts; the AI assistant reads your details only when it handles a message from you or a request about your sign-up (see "Who reads what you write").
Meetup members: how I use your Meetup information for the relaunch
Who: Giovanni Kerkhof, organiser of the Limitless Mindset Amsterdam Meetup group, the Netherlands. Contact: hello@limitlessmindsetamsterdam.com, or a message to me on Meetup.
What: the information Meetup shows me as organiser of this group: your name, city, the intro/bio you wrote, when you joined and last visited, and which group events you RSVP'd to or attended. From that I derive, for my own use, which kinds of events you joined (for example talks, trips, dance) and a rough order of whom to invite first. If I contact you, I keep a short record of that contact (date, how, and your answer — for example interested, declined, or don't contact me).
Why, and on what basis: to restart this group, to decide whom to invite first, and to respect anyone who says no — my legitimate interest in running the group I organise. It is not used for advertising, not sold, and not copied into any other project's mailing list.
Who else sees it, and AI: the records are kept on my own computer. Since 30 September 2026 the personal messages I send you on Meetup are written and sent by an AI assistant (Claude, by Anthropic, a US-based service) acting on my behalf from my Meetup account; I set the rules it follows, but I do not approve each message before it goes out. To write a message the assistant reads what is listed under What above: your name, city, intro/bio, join and last-visit dates and your RSVP history in this group, plus any reply you send. It also reads your replies in my Meetup inbox and records the outcome. Each such message says that it was written by my AI assistant and links to this section. The assistant writes to at most five new people a day, at most once a week per person, follows up at most once, and never writes again to anyone who says no. Once, on 2026-09-26, pseudonymised event history without names went to Cloudflare Workers AI for ranking. A second AI service (OpenAI) only reviewed the plan text, without member data. No other recipients. Transfers to the US: Anthropic relies on standard contractual clauses; Cloudflare relies on its certification under the EU–US Data Privacy Framework (with standard contractual clauses as fallback).
How to stop it: reply "stop" or "no" to any message and neither the assistant nor I will message you about this again; or email hello@limitlessmindsetamsterdam.com. If you would rather talk to me (a human) than to the assistant, say so in your reply and I will answer myself.
How long: derived data (bio copies, event themes, ranking) for members who are not contacted or do not engage was deleted on 25 October 2026 (final leftovers removed 27 October 2026); 31 March 2027 is the final review date for everything else. If you ask not to be contacted, I keep only a minimal note so that I can respect it.
Your rights: access, correction, deletion, restriction and objection — reply "no more" to any message from me, or email hello@limitlessmindsetamsterdam.com. You can also complain to the Dutch data protection authority (Autoriteit Persoonsgegevens).
Your say in this policy: this is the first privacy policy our Meetup group has ever had, and we are writing it in the open. We are curious how you, the members, want it: what you are comfortable with, what you would rather we did not do, and what is missing. The group sets its own rules, so this text will change with what members tell us. Reply to any message from me, or email hello@limitlessmindsetamsterdam.com; every suggestion is read and answered.
