What this site collects
Your answers and the pictures you upload aren’t stored on our servers (unless you ask us to keep your answers, as explained below): they stay in your own browser (localStorage and IndexedDB) until you download your site. You can delete them by clearing this site’s data in your browser. The sound setting is kept in your browser too. The only cookie is a technical one from Cloudflare, our host (cf_clearance): it tells people from bots and protects the site; it doesn’t follow you and needs no consent. We count visits with Cloudflare Web Analytics, which uses no cookies and builds no profile of you. No advertising.
We also count how often each kit’s page is seen, a name typed on it and its “Try it free” button pressed (never the name: only that one was typed), its wizard opened, each step reached, a photo added, the pay button or “We set it up” pressed, a payment confirmed and a site downloaded: only totals per day, kit, language and kind of screen (phone or desktop), kept with Cloudflare in the EU, with no cookies, nothing stored in your browser, no IP address and no identifier of any kind, so nothing in them says who you are. If you answer the wizard’s optional “What’s stopping you?” question, we keep your answer and anything you write (minus emails and phone numbers) with only the day, the kit and the language: nothing that identifies you.
When you buy, Stripe tells us your name, your email and your billing country, and whether the payment went through. We use them to deliver your site, help you with it and keep the records tax law asks for, for as long as it asks. If you choose “We set it up”, we use the content you send us (words, pictures and your business’s details) only to put your site together and publish it, and keep it while we host the site or until you ask us to delete it.
If you come through the link of someone who recommends Promti (an affiliate), their code travels in the page’s address, not in a cookie, and shows by the pay button, where you can change or clear it. If you pay with a code in, we keep that code with the payment’s reference, the day, the product and the amount, to pay their commission and keep the books. Never your name or your email. Your price is the same.
If you ask us to write to you
At the wizard’s last step you can ask us to send you your configuration and the link to pick it up again. If you do, with your email and the box ticked, we keep your email, your text answers (never the pictures, which stay only in your browser), the kit, the language, the day and the words of the box you agreed to. We use them to send you that link and, only if you ticked the second box, to write to you once more in case you have questions. No newsletters, no marketing. The answers are deleted after 90 days (the link stops working) and the rest after a year.
On “We set it up” you can ask us for a written proposal: we keep your email, the kind of business, what you need, the deadline and the words of the box you agreed to, to answer you with the proposal. It’s deleted after a year, or sooner if you ask.
On “AI rescue” (fixing apps that stop working because an AI model is switched off) you can ask us for a quote: we keep your email, what your app runs on, what breaks, the option you pick, the deadline and the words of the box you agreed to, to answer you with the quote. We never keep API keys: if you type something that looks like one, it isn’t sent. It’s deleted after a year, or sooner if you ask. That page’s free checker works only in your browser: what you paste into it is sent nowhere, and the open-source scanner (ai-model-sunset) runs on your computer and sends nothing either.
On that same page you can ask for email alerts before a model is switched off: we keep your email, the models you pick, where you came from (the site, the scanner or its GitHub Action), the alerts already sent and the words of the box you agreed to, only to write to you 30 and 7 days before each date. No marketing. You unsubscribe by replying «stop» to any alert, and we delete it then or, at the latest, after a year.
In every case the basis is your consent, which you can withdraw whenever you like by writing to hello@promti.app. It’s kept with Cloudflare, in the EU, and we pass it to nobody.
Services we rely on
Cloudflare hosts the site: like any host, it handles your IP address to serve the pages, protect them and count visits. The typefaces are served from this site itself: your browser doesn’t ask anyone else for them. Payments go through Stripe, on Stripe’s own page: we receive your email and whether the payment went through — never your card.
If you write to us
We use your message only to answer it.
Your rights
You can ask what we hold about you, and have it corrected or deleted, at hello@promti.app. You can also complain to your data protection authority — in Spain, the AEPD (aepd.es).
Terms of sale
What you buy
A Promti kit made into your website: the files of a finished site (HTML, CSS, JavaScript, your pictures and the typefaces), put together in your browser from what you enter in the wizard, plus the guides to put it online. You see it as it will be before you pay.
How you buy
You pick a kit, answer the wizard and see your site as it will be: anything that isn’t right, you fix there and then, before paying. At the last step you choose how you want it: to download it yourself, or for us to set it up (see “We set it up”, below). On Stripe’s payment page you check your email and your card before confirming. Stripe then emails you the receipt and the invoice. These terms are on this page for you to save or print; we don’t file a separate copy of each contract. The contract is in English or Spanish.
Price
Every kit costs €500, as shown on its page and at checkout. “We set it up” costs €750. It’s the final price, taxes included, paid once. Your domain, your hosting and the services you connect (Stripe, a form, email) are yours, and billed by them, not by us.
Payment
By card or the other methods Stripe offers, on Stripe’s own page.
Delivery
Straight away: after paying you come back to the wizard and download your site as a .zip file — again whenever you like, from the browser where you made it. Your answers and pictures live only in that browser (we keep no copy, except the text answers you’ve asked us to keep), so keep the .zip somewhere safe.
Licence
The site is yours: publish it for your business, host it wherever you like and change whatever you want, with no time limit. What you can’t do is sell or give away the kit or its code as a template, or use one kit to make sites for other businesses — each business needs its own. The open-source parts inside it (three.js, SplitType, a small piece of Vite and the typefaces) keep their own free licences, listed in the download’s LICENSES.txt.
Right of withdrawal
Buying online, you normally have 14 days to change your mind. With digital content, that right ends once delivery begins with your consent — so before paying, you ask for your site to be delivered straight away and confirm you know that downloading it ends your right to withdraw. Until you download it, you can still withdraw within 14 days of paying: write to hello@promti.app and we’ll refund the whole amount within 14 days, the same way you paid.
If something doesn’t work
If your site doesn’t work the way the wizard showed it, write to us and we’ll put it right; if we can’t, we’ll refund you.
We set it up (€750)
Instead of finishing it yourself in the wizard, you can ask us to set it up: you pick the kit, pay €750 and send us your content. It includes:
- everything the kit includes, under the same licence: the site is yours and, whenever you ask, we send you its files;
- putting it together with the words, pictures and details you send us, within what the kit lets you change (the same things the wizard asks);
- sending you a preview before it’s published and making one round of changes to the content you sent (a sentence, one of your pictures for another, a colour);
- publishing it at your domain, if you have one — you give us access to its settings (DNS) or make the changes we tell you — or, if you don’t have one yet, at a free address such as yourbusiness.pages.dev;
- hosting it on Cloudflare Pages’ free plan, with no fee to us. We can’t promise that plan will always stay the same: if it changes, or if you’d rather host it yourself, we send you all its files.
It doesn’t include: writing your words or taking your pictures (we use the ones you send); pages or sections the kit doesn’t have; a 3D model of your product for the Product kit; your domain, which you pay for to whoever sells it; the accounts of the services you connect (Stripe, the form, bookings), which are yours; or changes you want after it’s published.
Timing: we publish it within 48 working hours (Monday to Friday, not counting public holidays) of having all your content. After you pay, we write to the email you paid with to ask for it, and tell you if anything is missing; the time starts once we have it all. The time between our sending you the preview and your reply doesn’t count.
Changes after it’s published: changes you want once your site is live aren’t part of the price of “We set it up”. You can make them yourself, because the files are yours, or ask us: we tell you the price before doing anything and only go ahead if you agree. Fixing a mistake of ours isn’t a change: we fix it for free, as the guarantee says.
Right of withdrawal: you can withdraw as long as your site isn’t published, within 14 days of paying, even if we’ve started putting it together: write to hello@promti.app and we’ll refund the whole amount within 14 days, the same way you paid, with nothing taken off for the work done. Before paying, you ask us to start straight away and confirm you know that once your site is published, you can no longer withdraw.
Guarantee: if your published site doesn’t work the way you saw it in the preview we sent you, write to us and we’ll put it right; if we can’t, we’ll refund you.
Law
Spanish law applies. If you buy as a consumer, you keep the protection of the law where you live, and you can take any dispute to the courts there.
