1. Cookies
By default this site sets none. No session cookie, no preference cookie, no advertising cookie.
The one exception is Google Analytics, and only if you press Allow on the bar shown on your first visit. If you decline — or simply ignore it — no analytics cookie is ever written, because the script is never loaded at all.
| Cookie | Set by | Purpose | Lifetime |
|---|---|---|---|
_ga | Google Analytics | Distinguishes one visitor from another so visits are not double-counted. | 2 years |
_ga_<id> | Google Analytics | Keeps session state for the property. | 2 years |
Both appear only after you allow analytics. You can change your choice at any time, and clearing site data removes them.
You can verify all of this in your browser's developer tools, under Application or Storage.
2. What we do store on your device
Two entries in localStorage. That is a browser feature distinct from cookies: these
entries are never attached to network requests, and no other website can read them.
| Name | Value | Purpose | Written when |
|---|---|---|---|
rx-signatures |
Up to four small PNG images | Signatures you drew on the signature pad and chose to keep, so you do not have to redraw one for every exam. | Only if you press Save for later |
rx-consent |
yes or no |
Your answer to the analytics question, so you are not asked again on every page. | Only when you answer it |
That is the complete list. None of them is written unless you take the action described. If you only resize a file and leave, nothing at all is stored.
3. Saved signatures
A signature is personal, so this one deserves spelling out.
- It is written only when you press Save for later on the signature pad.
- It is stored in your own browser on that one device. It is not sent anywhere, is not part of any network request, and is not readable by any other website.
- We never see it. There is no server that could.
- Delete any saved signature with the × on its thumbnail, at any time.
- A maximum of four are kept; saving a fifth discards the oldest.
If you use a shared or public computer, delete your saved signatures before you leave, or simply never press Save — the pad works perfectly well without it.
4. Removing them
Clearing site data or browsing history for this domain removes all three entries, and the Google Analytics cookies if you allowed them. Saved signatures can also be removed individually from the signature pad. The site works without any of them — it opens in English, with an empty pad, and asks the analytics question again.
5. Third parties
One, and only with your permission: Google Analytics. Nothing else — no advertising network, no embedded video, no social widgets, no web fonts from another domain.
Every other file this page loads comes from this domain, and our Content Security Policy permits no destination except Google Analytics. See the privacy policy for what that does and does not guarantee.
