Nearly nothing, by design. A system built on auditable memory should be able to account for every byte it holds about you — so here is the full account.
Effective 7 July 2026 · covers amesemi.com · the formal companion to the FAQ's data answer
No cookies. No trackers. No ad pixels. No analytics identity. No account to create. You can read every page of this site and remain, to us, nobody in particular.
The one measurement that exists: anonymous page-speed telemetry from the hosting platform (Vercel Speed Insights) — timing numbers about how fast pages load, carrying no identity and no behaviour. It exists so slow pages get found and fixed.
Join the waitlist and exactly one datum is stored: your email address, held by Buttondown, the newsletter service that runs the list. It is double-opt-in — nothing is kept until you confirm — and it is used to write to you about Amesemi, nothing else. It is never sold, rented, or shared beyond that service.
Every email carries an unsubscribe link that works. Unsubscribing ends the mail; if you want the address itself gone, reply to any email we have sent and it will be deleted from the list.
Support runs through Stripe's hosted checkout. Card numbers go to Stripe and never touch Amesemi's side. What we can see is what any merchant sees on a receipt — your name, email, and the amount — and it is used only to deliver supporter benefits, honour the 14-day refund promise, and keep the books straight.
The site is served by Vercel, whose infrastructure keeps standard, short-lived access logs (the requesting address and the page asked for) as every host does, to serve pages and repel abuse. We don't use those logs to identify visitors.
The constellation, the replay, the counts — everything of Amesemi's memory shown on this site is a statistical shadow: memory kind and brightness, event type and rhythm. No text, names, goals, or paths ever leave the machine Amesemi runs on, and a leak scanner checks every deploy for exactly that before it is allowed to ship.
A small service worker caches the pages you visit in your own browser so the site opens offline. That cache lives on your device, belongs to you, reports nothing back, and clears the moment you tell your browser to clear it.
Ask what we hold about you and the answer arrives (it will be short). Ask for it corrected or deleted and it will be. There is no portal and no process: reply to any email Amesemi has sent you — the waitlist welcome or a Stripe receipt — and a human reads it.
If anything here changes materially, supporters and the waitlist hear by email before it takes effect, and this page carries its effective date. Superseded versions are kept, not erased.
The subscriber product this preview funds is local-first: your own Amesemi, whose memory of you lives on your machine, not on ours. Holding as little as possible about you isn't a policy we adopted — it is the architecture.
