Privacy.

Last updated: [launch date]

The short version: we keep your sign-in account and whether you've paid. If you join the email list, we keep your email address too. We count visits without cookies, and there are no ads and no tracking cookies. Fonts and lesson pages all come from this site. Only the sign-in code is loaded from Clerk, our sign-in service: on the sign-in and account pages, and on the home page while you're signed in, to show your profile picture.

Who's responsible

[seller's legal name], [address], Romania, is the data controller. For anything about your data, email [contact email].

What we keep and why

• Your account. Your email address and password, held by Clerk, our sign-in service, so you can sign in and keep what you paid for. If you sign in with Google instead, Google gives Clerk your name, email address and profile picture, and the home page shows that picture next to Your account. We never see your password. The legal basis is our contract with you (GDPR Art. 6(1)(b)).
• Your purchase record. Your account id, the Stripe payment id, whether it's paid or refunded, and the date. This is what unlocks the paid lessons. Same basis: the contract.
• Payment details. Stripe and Link handle the payment as merchant of record, under Stripe's privacy policy. They pass us the order details (such as your email, country, amount and payment id), never your card. We keep sales records because tax and accounting law requires it (Art. 6(1)(c)).
• Emails you send us. Kept so we can answer you and sort out your order.
• Server logs. Cloudflare, which hosts the site, handles your IP address and browser details to deliver pages and block attacks. The basis is our legitimate interest in a site that works and stays safe (Art. 6(1)(f)).

You need an email address to make an account. Without one you can still read lessons 0 to 3.

Cookies

A cookie is a small note a website keeps in your browser. The only cookies are the sign-in cookies Clerk sets to keep you signed in, and its sign-in box keeps a few technical settings in your browser's storage. They're needed for the site to work, so there's no cookie banner. The lessons store a few things in your own browser: your sound and speed settings, whether the Python notes are shown, the step you reached in each lesson, so a refresh brings you back to it, the XP you earned in each lesson and the achievements you unlocked, and which lessons you finished, so the home page can tick them. None of it ever leaves your computer.

The email list

If you join the list on the home page or at the end of a free lesson, we keep your email address, the page the form was on, and the time you ticked the box. We use it to email you about new lessons and the launch price. The legal basis is your consent (GDPR Art. 6(1)(a)). It's stored in Cloudflare D1, the same database the site already uses for purchase records. We keep it until you leave. To leave, use the link in every email, or write to [contact email]. We never sell it or share it. When we add an email-sending service, this page will name it before the first email goes out.

Visit counts

The site uses Cloudflare Web Analytics. Cloudflare says it sets no cookies, uses no localStorage and doesn't fingerprint visitors. It gives us page views, referrers, countries and device types.

Who else handles your data

• Clerk, for sign-in: privacy policy, data processing agreement.
• Cloudflare, for hosting, our database and visit counts: privacy policy, data processing agreement.
• Stripe and Link, for payments, as their own controller: privacy policy.

These companies are based in the US and may handle data outside the EU, with the safeguards set out in their data processing terms. We don't sell your data or share it with anyone else.

How long we keep it

Your account and purchase record stay while you have an account. Your place on the email list stays until you leave it. Ask us to delete them and we will, except for the sales records the law makes us keep, and only for as long as it does.

Your rights

You can ask to see your data, correct it, delete it, limit how we use it, object to its use, or get a copy to take elsewhere. Email [contact email] and we'll answer within a month. You can also complain to a data protection authority: in Romania that's ANSPDCP, or use the one where you live.

We don't make automated decisions about you and we don't build profiles.

Changes

If this page changes, the date at the top changes with it. If the change matters to you, we'll email you.
