Privacy Policy

Last updated November 2026

Quintus is a study tool for the Vergil and Pliny readings in AP® Latin. It is built to know as little about you as possible.

What stays on your device

There are no accounts. Your practice progress (which questions you have answered, points, rank, settings) is stored in your browser on your own device. We never receive it. Clearing your browser's site data, or using "Reset my progress" in the app, erases it.

What we do not do

We do not run advertising, analytics or tracking scripts, and we do not sell or share personal information.

If you buy

Checkout is handled by our payment processor and merchant of record, Lemon Squeezy. It collects your name, email, billing country and payment details, issues your license key and receipt, and handles sales tax. We do not see or store your card details. We may receive your email address and order details so that we can provide support and refunds. Lemon Squeezy's own privacy policy governs what it collects.

License checks

When you activate, re-check or release a license key, the app sends the key and a random device label to our server, which forwards the request to Lemon Squeezy to confirm it is valid. We do not keep a copy of your key in a database of our own. The key is also saved in your browser so the app can unlock itself.

Hosting and fonts

Our site is served by Cloudflare, which processes standard request data (such as your IP address and browser type) to deliver and secure the site. The pages load typefaces from Google Fonts, so Google also receives your IP address when a page loads.

Children

Quintus collects no personal information from people who use the free sample or the app. It is not directed to children under 13, and purchases should be made by a parent, guardian or adult.

Your choices

You can erase your progress at any time, release a device from your license inside the app, or ask us about a purchase. Contact: YOUR-EMAIL@YOUR-DOMAIN.

Changes

If we change this policy we will update the date above.
