Cookies are small text files stored on your device. We use a deliberately small set of cookies and similar technologies (local storage) to run On Paper, remember your preferences, and understand how the product is used. This policy explains what we use and how to control it.
These keep you signed in, maintain your secure session, route payments safely, and protect against fraud and abuse. The service cannot function without them, so they cannot be switched off.
These remember choices so your experience is consistent across visits and devices — for example your learning progress and view settings. They’re convenience-only and can be cleared anytime.
These help us understand which features are used and where the product can improve. We aggregate and minimize this data where we can, and we do not use it to build advertising profiles.
Some functionality relies on trusted providers who may set their own cookies when you use their features — notably our payments partner (Stripe) during checkout, and sign-in. Their use of cookies is governed by their own policies.
You can accept or decline non-essential cookies from the banner shown on your first visit, and change your mind anytime. You can also control or clear cookies in your browser settings — note that blocking strictly necessary cookies may break sign-in and payments.
We do not sell your personal information, and we do not use cookies to sell or share it with data brokers.
