Víkingur is an AI-powered Icelandic learning app. It's run by Kajan Bulić, an individual sole trader based in Iceland — not a company. If anything in this policy is unclear, or you want to exercise any of the rights below, just email hello@vikingur.app and I'll deal with it personally. Postal address: Víkingur · Kajan Bulić · Hraunholar 8Astc210bær · Iceland.
Víkingur hasn't opened to the public yet. Right now this site collects three things, all optional: your email address if you join the waitlist (we send one email on the day the app opens, and nothing before it); your email address if you subscribe to the Journal (one email per new piece, with a one-click unsubscribe in every one); and anonymous product analytics on the pages themselves — which sections get read, which buttons get pressed — with no cookie and no identifier that survives the visit, so a return visit looks like a new one to us. The rest of this policy describes what happens once the full app opens, so you know what you're signing up for in advance. We'll update this page the moment that changes.
We only collect what the app actually needs to work. Here's the full list, and the reason for each:
| What | Why |
|---|---|
| Your email address | To create your account and send you important account emails. Before launch, a waitlist address is used for exactly one email, on the day the app opens; a Journal address is used for one email per new piece. |
| Your password | To log you in. We never see it in plain text — it's hashed by our authentication provider, Supabase, before it ever reaches our database. |
| Your onboarding answers (native language, job/occupation, interests, why you're learning, your self-assessed level, and your learning goals) | This is the core of the product — Víkingur builds every lesson around who you are, so this is the information that makes that possible. |
| Your learning progress (lessons completed, words you've learned, quiz results, streaks, badges earned) | To track how you're doing, decide what to teach you next, and show you your own progress. |
| Payment details | Handled entirely by Paddle, our payment provider — we never see or store your card details ourselves. See "Who we share it with" below. |
We don't collect anything beyond this. We don't run ads, we don't sell your data to anyone, and we don't buy or sell data lists.
Under GDPR, we need a valid reason to process your data. Here's ours for each category above:
We use a small number of outside services to run Víkingur. We don't sell your data to any of them — they process it strictly on our behalf, to provide the specific function listed below.
| Provider | What they do | Region |
|---|---|---|
| Supabase | Our database and login system — stores your account, profile, and progress data. | EU |
| Vercel | Hosts the app itself. | Global CDN |
| Anthropic (Claude) | Generates your personalized lessons. Your profile and learning data are included in the prompts we send it, so it can tailor content to you. | United States |
| Resend | Sends account and notification emails. | EU |
| Paddle | Handles all payments and billing. Paddle is the Merchant of Record — legally, they are the seller for every transaction, not us. They handle your payment details directly; we never see your full card number. | Global |
| Microsoft Azure | Converts lesson text into spoken Icelandic audio (text-to-speech). | EU |
| OpenAI (Whisper) | Converts your spoken voice into text, for voice-based exercises and conversation practice. | United States |
| DeepL | Translates the text you type into the Translate tool. Only that text is sent, nothing about your account. | EU |
| Unsplash, Pexels and Pixabay | Supply the photographs on vocabulary cards and Journal covers. We send them a search phrase describing the picture we need, never anything about you — but the photo itself loads from their servers, so like any image on the web they see your IP address when it loads. | United States (Unsplash), EU (Pexels, Pixabay) |
| PostHog | Product analytics — helps us understand which features are actually used, so we can improve the app. Cookieless, no advertising or data-selling use. | EU |
That's the complete list. We don't use any other third-party analytics, advertising, or tracking tools. The news stories in the app are written from the headlines and summaries in the public RSS feeds of RÚV and Vísir, which we fetch ourselves; nothing about you goes to them.
A few of the providers above — Anthropic, OpenAI and Unsplash — are based in the United States. Whenever we transfer personal data outside the EEA, we rely on recognized legal safeguards (such as Standard Contractual Clauses or an equivalent adequacy mechanism) that require the receiving provider to protect your data to a standard equivalent to EU law, regardless of where it's processed.
We keep your account and learning data for as long as your account is active. If you delete your account (Settings → Delete account, or by emailing us), we delete your personal data within 30 days, except where we're legally required to keep certain records for longer — for example, transaction records Paddle keeps for tax purposes. A waitlist address, if you never create an account, is kept until we have sent the one opening email or until you ask us to remove it, whichever comes first. A Journal address is kept until you unsubscribe.
Under GDPR (and equivalent laws elsewhere), you have the right to:
To exercise any of these, email hello@vikingur.app. You also have the right to lodge a complaint with your local data protection authority if you think we've gotten something wrong.
We use strictly necessary cookies to keep you logged in and to remember basic preferences. We don't use advertising or cross-site tracking cookies. The landing page also remembers, in your own browser's storage, that you have already joined the waitlist, so it doesn't ask again; that never leaves your device. Our analytics set no cookie at all.
Víkingur isn't intended for children under 16, and we don't knowingly collect data from them.
If we make a meaningful change to this policy, we'll update the date at the top and, for significant changes, email you directly.
