Privacy policy

Last updated November 13, 2026

This page covers the Fiola website and quiz. The app will have its own privacy policy when it opens.

What we collect

• Your quiz answers, so we can show your result and prepare your plan.
• Your email address, if you give it, to send your plan and news about Fiola. You can unsubscribe anytime.
• How you found us: the ad or link you came from (utm tags and the Meta click id), and which quiz steps you reached.
• Payment: Stripe handles your card. We never see or store your card number. We receive your email, the amount and the payment status.

Who we work with

• Cloudflare hosts the site and our database.
• Stripe processes payments.
• Meta (Facebook, Instagram) measures our ads. Meta learns that a visit, a quiz start or end, an email sign-up, a checkout or a purchase happened, with a hashed email when you give one. Meta never receives your quiz answers.
• PostHog counts how many people reach each step, without your answers.
• Resend sends our emails.

Your sleep and health answers

Some quiz answers describe your sleep. We use them only to show your result and prepare your plan. We don't sell them, we don't share them with advertisers, and we don't use them to target ads.

We don't sell your data

We never sell your personal information. Sending ad measurement events to Meta may count as "sharing" under some US state laws. If your browser sends a Global Privacy Control signal, we don't load the Meta pixel. You can also ask us to stop by writing to us.

Your choices

Write to hello@fiola.app to see, correct or delete what we hold about you, or to stop emails. We answer within 30 days, usually the same week.

How long we keep it

Quiz answers and step data for up to 24 months. Payment records as long as tax law requires.
