Cookie Policy
What this page covers
This policy explains the cookies and similar storage technologies used on this site, what they do, and how to control them. It sits alongside our Privacy Policy, which covers personal data more broadly.
Worth saying first: none of this affects your documents. Your files are processed in your browser and are never uploaded, whatever you decide about cookies.
What cookies are
A cookie is a small text file that a website asks your browser to store and send back on later requests. Cookies make it possible to remember things between page loads. Related technologies — local storage and session storage — also keep data in your browser, but unlike cookies they are never automatically transmitted to a server.
Categories we use
1. Strictly necessary (always on)
These make the site work and cannot be switched off. We use local storage rather than cookies for both, which means the data stays on your device and is never sent anywhere.
| Name | Type | Purpose | Duration |
|---|---|---|---|
pdfdad-theme | Local storage | Remembers whether you chose light or dark mode. | Until you clear it |
pdfdad-consent | Local storage | Remembers the choice you made in the cookie banner, so you are not asked again. | Until you clear it |
2. Analytics (optional — off unless you accept)
If you consent, Google Analytics helps us see which tools are used and which pages error, so we know what to fix first. IP addresses are anonymised. If you decline, the Analytics script is never loaded.
| Name | Provider | Purpose | Duration |
|---|---|---|---|
_ga | Distinguishes one browser from another. | 2 years | |
_ga_<id> | Maintains the session state. | 2 years |
3. Advertising (optional — off unless you accept)
The site is funded by advertising. If you consent, Google AdSense and its partners set cookies to measure and personalise the ads you see. If you decline, you still see advertisements, but they are contextual rather than personalised.
| Name | Provider | Purpose | Duration |
|---|---|---|---|
IDE (DoubleClick DART) | Google / DoubleClick | Serves ads based on your visits to this and other sites, and measures their performance. | Up to 13 months |
test_cookie | Google / DoubleClick | Checks whether your browser accepts cookies at all. | 15 minutes |
__gads, __gpi | Measures ad interactions and limits how often you see the same ad. | Up to 13 months | |
| Partner cookies | Various ad networks | Third-party vendors other than Google may serve ads and set their own cookies. | Varies by vendor |
Consent Mode
We implement Google Consent Mode v2. Until you choose, advertising and analytics storage are set to denied and the corresponding scripts do not load. Your decision updates that state immediately.
How to control cookies
- On this site: use the "Cookie settings" link in the footer of any page to reopen the banner and change your choice at any time.
- In your browser: every major browser lets you block or delete cookies, in Settings under Privacy. Blocking all cookies may break other websites; it will not break the tools here.
- Personalised advertising specifically: opt out at Google Ads Settings, aboutads.info/choices or youronlinechoices.com.
- Everything at once: clearing your browser's site data for this domain removes both the local-storage entries and any cookies, and you will be asked again on your next visit.
Content delivery networks
The PDF libraries are loaded from jsDelivr and one web font from Google Fonts. These set no cookies, but any request to a server necessarily reveals your IP address to it. Local copies of every library ship with the site as a fallback, and your browser caches them after first use.
Changes
We will update this page when our cookie use changes, and the date at the top will reflect that. Questions go to support@pdfdad.com.
