Privacy policy

Last updated: 6 October 2026. This covers doyouconvert.app, the studio at studio.doyouconvert.app, the 5sec.io website and the Five-Second Test Chrome extension. Maxlie BV runs all of them, on the same systems.

What we collect and why

• When you run a test (website or extension): the page URL, the visible above-the-fold text, and a screenshot of the visible page area. These are sent to our servers and to our AI provider (Anthropic) solely to generate your audit. Audit results are stored so you can revisit and share them.
• Cookies: two strictly necessary cookies: an anonymous identifier to enforce the free-test quota, and a session cookie when you sign in. The extension and the studio use the same cookies as the website. On doyouconvert.app itself the only necessary cookie is the one that remembers your cookie choice. No advertising or cross-site tracking cookies. Analytics cookies are only set if you accept them in the cookie banner; if you reject or ignore it, none are loaded. You can change your choice at any time via cookie settings, and your choice is remembered for six months in a cookie named fst_consent.
• When you sign in: your email address, used for sign-in links, your test history and credit balance.
• When you buy something: payment is handled entirely by Stripe. We never see or store your card details. Stripe shares with us your email, company details and VAT number so we can fulfil your order and issue an invoice.
• When you order an audit or apply for a free one: the details you submit (name, company, email, website, competitor URLs) are used to produce and deliver the audit.

What we don’t do

• We don’t sell or share your data with third parties beyond the processors named above (Anthropic for analysis, Stripe for payments, Resend for email, Vercel for hosting).
• We don’t collect your browsing history. The extension only reads the page you’re on at the moment you click it, and only after you click it.
• We don’t use your pages or screenshots to train AI models.

Retention and your rights

Audit results are kept so your test history and shared report links keep working. You can ask us at any time to see or delete the data we hold about you: email hello [at] maxlie [dot] be and we’ll handle it within 30 days.
