Privacy policy

Last updated: 5 November 2026.

Who we are

Ask Once is run by Rokas Ščesnavičius, an individual based in France. We decide how your personal data is used, so we're the data controller. You can reach us at [email protected], or through the contact form.

What we collect, and why

• Your email address, from your purchase. We use it to sign you in and to send you sign-in links. We need it to give you the course you bought.
• The name you give at checkout. We use it to put on your certificate, and for nothing else.
• Your order details: the order number, whether it's paid or refunded, and when you agreed to start the course straight away. We need these to give you access, and to keep a record of the sale.
• Your progress: how far you've got in each lesson, so you can carry on where you stopped, and so we can check that you've finished before giving you a certificate.
• A session cookie that keeps you signed in. It's the only cookie we set, it's needed for the site to work, and we don't use it for tracking.
• Messages you send us through the contact form, and your email address so we can reply. They go to our inbox and aren't stored in the site's database.

Our servers briefly use your internet address to limit repeated requests, and keep it in memory and in short-lived security logs. We don't use advertising or analytics tools.

What stays on your device

The numbers you type into your tool, your answers in the lessons, and your free lesson progress are kept in your own browser. They don't come to us. Clearing your browser's data removes them.

What we never see

We never see your card details. Stripe takes your payment on its own page.

Who else handles your data

• Stripe sells the course on our behalf as merchant of record, takes your payment and handles tax. Your receipt comes from Link, which is part of Stripe. It uses your details under its own privacy policy.
• Resend sends our emails, so it handles your email address and the messages we send you.
• Cloudflare sits in front of our site, to protect it and deliver it quickly. Your visits pass through it, including your internet address.
• OVH hosts our servers and database.

We don't sell your data. Some of these companies may handle data outside the European Economic Area. Where they do, they must use the safeguards the law requires.

How long we keep it

We keep your account, order and progress for as long as you have the course, so you can come back to it. If you ask us to delete your account, we delete your email address, name and progress, unless the law requires us to keep a record of the sale. Stripe keeps its own payment records. Contact messages stay in our inbox for as long as we need them to help you.

Your rights

You can ask us for a copy of your data, and ask us to correct or delete it. You can also object to how we use it, or ask us to limit that use, and ask for your data in a form you can move elsewhere. To do any of this, contact us. If you're unhappy with how we've handled your data, you can complain to your local data protection authority.

Changes

If we change this policy, we'll update it here and change the date at the top.
