This page is short because the answer is short. Four things on this site collect anything at all, and the table below is the whole story. What each one takes, where it goes, how long it stays, and how to get it removed.
Nothing is sold. There’s no ad network, no third-party tracking, and no mailing list. Your email address is used to write back to you and for nothing else.
| Surface | What it takes | Where it goes | How long | To remove it |
|---|---|---|---|---|
| The contact form | Your name, your email address, and the message. | Sent as one email to my inbox. Nothing lands in a database. | As long as the correspondence is useful. | Ask, and it's deleted. |
| The assistant | Your question, the answer, the page and section you asked from, any text you have highlighted on that page when you ask (up to a thousand characters — it travels with the question either way), and a salted hash of your IP address. Never the address itself. | A private review log on my own systems, off this site, which I read to improve it. To produce the answer, the question — together with the conversation so far and any highlighted text — passes through OpenRouter to Google, or to a fallback model from Alibaba when the primary is unavailable. | 180 days, then deleted automatically. | Ask through the contact form and it goes sooner. |
| Vercel Analytics and Speed Insights | Page views and page-speed timings: URL, referrer, country and region, browser and device type. No cookies, no cross-site identifier. | Vercel, as aggregate counts only. | The visitor session hash is discarded after 24 hours. The speed timings are never tied to a visitor at all. | Nothing here can identify you, so there's nothing to remove. |
| The bot check (Cloudflare Turnstile) | A token proving you're probably human. Cloudflare sees your IP address while checking it. | Verified against Cloudflare server-side, then discarded. | This site stores nothing from it. | Nothing stored, nothing to remove. |
The detail behind two of those rows. The contact form uses your IP address transiently, for rate limiting and the bot check, and does not store it or put it in the email. The assistant’s log keeps a salted one-way hash of your IP, enough to recognize one abuser across a session and not enough to turn back into a person. Its 180-day deletion is enforced in code, not by calendar reminder.
Third parties that touch data in the table, with their own policies: Vercel hosts the site and runs the analytics, Cloudflare runs the bot check, and OpenRouter routes assistant questions to Google — or, when the primary model is unavailable, to Alibaba — to generate answers. The assistant’s review log itself lives on my own hardware, not with any of them. Vercel, as any host would, also keeps standard server request logs.
To ask for deletion, or to ask anything this page doesn’t answer, use the contact form. It reaches me directly.
