Cookies and storage
This site sets no advertising cookies, no tracking cookies and no third-party cookies. There is no consent banner because there is nothing to consent to.
Everything stored in your browser is listed below. The list is complete: if something is not here and your browser has it from us, that is a bug.
Cookies
| Name | Purpose | Lifetime |
|---|---|---|
haydevclub-locale | Remembers which language you read, so that the site root sends you to the same one next time. | 1 year |
The cookie holds a language code and nothing else. It is not an identifier: a thousand readers of the English version all store the same value.
Local storage
| Key | Purpose | Lifetime |
|---|---|---|
haydevclub-theme | Remembers whether you chose light, dark, or the system theme, so the page does not flash the wrong colour before it loads. | Until cleared |
haydevclub-app-invite | Counts page views up to ten and remembers when you said “Not now”, so the app is suggested only after the first page and not again for 90 days. | Until cleared |
haydevclub-install-banner | Remembers that you closed the offer to install the app at the top of the page, so it does not come back. | Until cleared |
haydevclub-push-topics | The notification topics you chose, so the settings show your choice. Set only if you turn notifications on. | Until you turn notifications off |
Local storage never leaves your browser: it is not sent with requests and we cannot read it on the server.
Offline copies
The site installs a service worker: a small script that lets it work as an app and open without a connection. It keeps, in your browser’s cache storage:
| Cache | What it holds | Lifetime |
|---|---|---|
hdc-pages | Copies of the last 40 pages you opened | Replaced as you read; until cleared |
hdc-assets | Fonts, icons, images and code of the site, up to 300 files | Replaced as the site changes; until cleared |
hdc-offline-… | The page shown when you are offline and a page has not been saved yet | Replaced with every new version of the site |
These are copies of our public pages, not information about you, and they never leave your device.
What third parties may store
Until you press play on a video, no third party is involved at all and nothing
of theirs is stored. When you press play, the player is loaded from
youtube-nocookie.com, which is designed to avoid setting cookies for
advertising—but from that moment YouTube’s own rules apply.
Maps are never embedded: the venue address is text on our page, and a map opens on the provider’s site only if you choose to open it.
Analytics
Analytics on this site, when enabled, works without cookies and without identifying visitors. It counts page views and measures how fast pages are; it does not build a profile and does not follow you to other sites.
Removing everything
Clearing site data for this domain in your browser removes everything above, including the offline copies. The site will keep working—it will simply follow your system theme and ask your browser which language you prefer. If you had turned notifications on, clearing site data also removes the subscription from your browser; we delete our record of it the next time a notification fails to reach it.
