Privacy
Short version: we ask for an email address so we can send you the worksheet. We set no cookies. We count visits with Cloudflare Web Analytics, which uses no cookies and does not track you from site to site. Apart from that script, and Stripe's form on the audit page, we load nothing from other companies' servers. You can leave at any time and we delete your address.
Who is responsible for your data
Stanki Guild Spółka Z Ograniczoną Odpowiedzialnością (Stanki Guild sp. z o.o.), ul. Adama Mickiewicza 13/4, 82-300 Elbląg, Poland. KRS 0001264778, NIP 5783187890, REGON 545649454. Campsite Math is our project.
Write to privacy@campsitemath.com about anything on this page. We have not appointed a statutory Data Protection Officer, because we are not required to. That address reaches us directly.
What we collect, and why
| What | Why | Legal basis | How long |
|---|---|---|---|
| Your email address, and which link you came from (a letter such as S or L, or "planner") | To send you the worksheet and the follow-up emails you asked for, and to learn which video earned the sign-up | Your consent. You confirm by clicking a link in the first email; until you do, we send nothing else | Until you unsubscribe or ask us to delete it |
| Server log: your IP address, the time, the page, and your browser's user-agent string | To keep the site up and to see abuse. Every web server records this | Our legitimate interest in running a working, secure site | 14 days, then the file is rotated away |
| A page view counted by Cloudflare Web Analytics: the page, the site you came from, your country, and your browser and device type | To see which pages and which videos bring visitors, in totals only | Our legitimate interest in knowing whether the site is used. No cookies, no profile of you | Kept by Cloudflare in aggregate form; we see totals, never a list of visitors |
| Whether you opened one of our emails, and which link you clicked | To see which emails are worth sending. Kit records this for us, the way every newsletter tool does | Your consent, the same one that put you on the list | For as long as you are on the list |
| If you buy the audit: your email, what you paid, and your three answers (memberships, nights a year, nightly rate) | To prepare your audit PDF, send it to you, and refund you if you ask | Performing the purchase you asked for, and our legal duty to keep sales records | Your answers 12 months, so a question about your audit can still be answered; payment records as long as tax law requires (5 years in Poland) |
| An email you send us | To answer it | Our legitimate interest in replying to you | It stays in the mailbox until we clear it out |
What we do not do
- No cookies. This site sets none. We checked on 2026-09-20 and no page sends a cookie header. That is also why you see no cookie banner: there is nothing to agree to. One exception: the audit page loads Stripe's payment form, and Stripe sets its own cookies there to prevent card fraud. No other page loads anything from Stripe.
- No tracking pixels and no advertising analytics. No Google Analytics, no Meta pixel, nothing similar. We count visits with Cloudflare Web Analytics only; in Cloudflare's words it "does not use any client-side state, such as cookies or localStorage, to collect usage metrics" and does not "fingerprint" individuals (cloudflare.com/web-analytics, read 2026-09-23).
- Almost nothing loaded from other companies. Every font, image and stylesheet comes from our own server. The one exception on every page is Cloudflare's counting script, so Cloudflare sees that a page was viewed.
- We never sell or rent your address, and we do not use it to advertise other companies' products to you.
Who else touches your address
Only the companies that make the emails work, and only for that:
- Stripe (Stripe Payments Europe, Ireland) takes the payment if you buy the audit. Your card details go to Stripe and never reach us; we see your email, the amount and whether it was paid.
- Kit (ConvertKit LLC, United States) stores the subscriber list and sends the emails you signed up for.
- Resend (United States) delivers mail we send from our own address.
- Mail you write to us arrives on our own server in Poland.
Kit and Resend are in the United States, so your address is transferred outside the European Economic Area. That transfer happens under the data-processing terms we have with them. If you would rather not have your address leave the EEA, do not sign up; you can still read every page and download the worksheet from the links on this site without giving us anything.
Your rights
You can ask us to show you what we hold, correct it, delete it, limit what we do with it, object to it, or hand it to you in a portable file. You can withdraw your consent whenever you like, which does not undo what we did before you withdrew it.
The fastest route out is the unsubscribe link at the bottom of every email we send. It works immediately and needs no explanation. You can also write to privacy@campsitemath.com and we will delete your address.
If you think we have handled your data badly, you can complain to the Polish supervisory authority: Prezes Urzedu Ochrony Danych Osobowych, ul. Stawki 2, 00-193 Warszawa, Poland (uodo.gov.pl). You may also complain to the authority where you live.
Two more things
This site is not aimed at children, and we do not knowingly collect data from anyone under 16.
We do not make any automated decision about you, and we do not profile you.
Changes
If we change this page we change the date below and say what changed. We will not quietly start collecting something new.
This version: 2026-09-23. Changed on 2026-09-22: added the audit purchase and Stripe as the payment processor.
