What is stored on your device and why there is no cookie banner.
A cookie is a small file that a website stores in your browser to recognise you on your next visit. Alongside cookies, sites can store information in the browser's local storage, which for the purposes of this policy works the same and is explained the same. Here is everything Petit Drac stores on your device, without exception.
Petit Drac only uses storage that is strictly necessary to provide the service you asked for: keeping your session open, making the application work and keeping the contact form from becoming a spam channel. Article 22.2 of the Spanish LSSI exempts this kind of storage from prior consent, which is why you won't see any cookie banner.
There are no analytics, advertising, social network or third-party measurement cookies. Your behaviour is not recorded and you are not followed across sites.
The notifications' service worker falls under the same case: it is only installed when you turn them on, which is requesting that service, and without it they cannot reach you.
| Name | Type | What it's for | Duration |
|---|---|---|---|
| petitdrac_sesion | First-party cookie, technical | Keeping your session open so you're not asked for your password on every screen. It is signed, HttpOnly, SameSite=Lax and Secure under https | 180 days, or until you sign out |
| petitdrac-cache:… | First-party local storage | A copy of your progress in this browser, so the application responds instantly without waiting for the network and keeps working offline | Until you sign out or clear the site data |
| sw.js | First-party service worker | A small program the browser keeps so it can receive and show notifications even when Petit Drac isn't open. It stores no data about you and does nothing else. It's only installed if you turn on notifications | Until you turn them off or clear the site data |
| _GRECAPTCHA | Google cookie, technical | Set by reCAPTCHA when the contact page of the public website is opened, to tell a person from an automated program. Only on that page: no screen of the application loads it | Six months, according to Google |
Your preferences —voice, text size and pronunciation— are not stored separately: they travel inside your progress, so they follow you from one device to another.
If you use the Google sign-in button, its script (accounts.google.com) sets its own cookies to recognise you and for its security. They are Google's cookies, not Petit Drac's: the owner can neither read nor control them, and they are governed by Google's cookie and privacy policies. They only load when the sign-in screen is shown; once you're signed in, that script is not downloaded.
And if you write through the contact form on the public website, its anti-spam (reCAPTCHA, at www.google.com) does the same: it loads its script and sets the _GRECAPTCHA cookie. They are also Google's and governed by its policies. It is the only page on the site that loads it, and the form itself says so with links to those policies.
If you turn on notifications, your browser stays connected to its maker's notification service so it can receive them. That connection is opened and managed by the browser itself, installs no Petit Drac cookies and is governed by that maker's policy.
And there are no other third parties: the typeface is served from this same site and not from a CDN, so outside those cases there is no other domain your browser has to request anything from or to which it communicates your IP address.
The most direct way is to sign out from your avatar menu: that deletes the session cookie and the local copy of your progress. Your progress is not lost, because it remains stored on the server.
You can also clear and block storage from your browser's settings, under privacy or site data. Every browser calls it something different, but they all have it.
If you completely block storage for this site, your session cannot be kept open and the application will not be able to show you your progress. Here it is not a frill: it is the piece that holds up access.
If Petit Drac ever added storage that was not strictly necessary, this page would be updated and you would be asked for consent before it was installed.
