## How to subscribe

1. Pick a plan on this page and press "Subscribe". If you are not logged in, the login window opens first: log in or create an account, registration is free.
2. You go to the PayPal page and confirm the subscription there. Card details are entered only at PayPal; our site never receives them.
3. After you confirm, PayPal sends you back to your account and the plan switches on within a few seconds.
4. The subscription renews every month until you cancel it. Cancelling and changing the plan are done in your account.
5. In "Settings" choose which kinds of analysis to compute and show on the right; the choice is kept in your browser.

## Payment

- **PayPal.** Pay for the subscription with your PayPal account.
- **Renews every month.** The subscription renews monthly until you cancel it. You can cancel at any time in your account.
- **No card data.** The site never asks for or receives bank-card data: it is entered only at PayPal.
- **Texts are not stored.** The text goes to the server only for analysis and is not stored anywhere.

## Good to know

The score is based on statistical features of the text; thresholds are provisional and not yet calibrated. The result is a guide, not proof of authorship. The text is sent to the server only for analysis and is not stored.
