Privacy

What you write is not sent

The checking of what you write in the square happens entirely in your own browser. Neither your strokes nor a name you type are sent to a server.

Cookies and analytics

This site sets no cookies. It uses no analytics or advertising tools and no third-party scripts. The typefaces are served from this site too.

The host (Cloudflare)

This site is served by Cloudflare Pages. As the host, Cloudflare technically processes the visitor's IP address in order to deliver the pages. In the served pages we observe no active measurement script for analytics. This site does not use access records to identify anyone.

The app

The iPhone app uses no account, no location and no advertising. It handles no photos, and what you write and your strokes never leave the device.

Usage statistics: the app sends counts of screens opened and actions taken to our own server (Cloudflare), tied to a random number the app made on your phone (the installation ID). That number is not your name. We also record the app version, the phone model, the system version, the language, the region set on the phone and the country (derived from your IP address at the moment of the request; we do not store the IP address). When the purchase service is active, we link that number to the random user ID that RevenueCat assigns. The statistics are not shared with any third party other than Cloudflare, which hosts them.

When it opens, the app also fetches a few small settings (for example what the purchase screen shows) from the same server. That request carries neither what you write nor the installation ID. Like any internet request it shows your IP address to that server, which does not store it.

Purchases are processed by Apple, and we use RevenueCat to know whether a purchase is active. We do not receive your name, Apple ID or payment method.

In the app, in settings under "Privacy", you can: see and copy the installation ID; ask for your data to be deleted with an email that is already written; turn the usage statistics off (when off, nothing is sent or kept, and anything waiting is discarded); and delete the sheets, unfinished sheets and chosen letter stored on the phone (with a few seconds to undo; your purchase is not touched).

To ask for access to or deletion of your data, write to the address below or use "Ask for my data to be deleted" in the app. We reply within one month. The app has no accounts, so we cannot find data about you on our own: if you give us the installation ID, we find and delete the statistics tied to it. If you have deleted the app or its data since, the number is new and we cannot link older records to you. Purchase records are held by Apple and RevenueCat, and you can ask them directly. You can also complain to a supervisory authority, such as the Spanish data protection agency (AEPD).
