1. What cookies and local storage are
A cookie is a small text file a site asks your browser to store and send back on later requests. Local storage is a similar mechanism, except the data stays on your device and is read only by scripts running on this site — it is not attached to requests. We use both, and for transparency we list them together here, because the privacy question is the same: something is being kept on your device.
We use these technologies for three purposes only: to make the site work, to remember preferences you set, and — with your consent — to count how the guides and the playground are used in aggregate. We do not use advertising cookies, we do not build profiles, and we do not participate in cross-site tracking networks.
2. Your choices
On your first visit a banner offers three options. Accept All enables essential, analytics and functional items. Reject Non-Essential keeps only the essential items needed to serve the site and record your choice. Preferences lets you enable analytics and functional categories independently. Your decision is stored on your device so the banner does not reappear on every page. To change it later, clear this site's storage in your browser and reload the page; the banner will appear again.
3. Cookies and storage items we use
Strictly necessary
| Name | Type | Purpose | Duration |
|---|---|---|---|
| bsq-cookie-choice | Local storage | Records your banner decision so it is not shown again and so optional scripts stay off if you declined. | 12 months |
| bsq-session | First-party cookie | Maintains request integrity and helps our host mitigate abusive traffic. | Session |
| __cf-origin | First-party cookie (CDN) | Routes your request to the nearest edge location and applies rate limiting. | Up to 30 minutes |
Analytics — consent required
| Name | Type | Purpose | Duration |
|---|---|---|---|
| bsq-analytics-id | First-party cookie | Distinguishes one browser from another so page views are not double counted. Contains a random value, no personal identifiers. | 13 months |
| bsq-pattern-events | Local storage | Buffers which pattern presets were opened so events can be sent in one batch rather than one request per click. | 7 days |
Functional — consent required
| Name | Type | Purpose | Duration |
|---|---|---|---|
| bsq-playground-state | Local storage | Remembers your last preset plus the speed, intensity, delay and direction values so returning to the playground restores your setup. | 6 months |
| bsq-motion-pref | Local storage | Stores a manual "reduce preview motion" choice when it differs from your operating system setting. | 6 months |
4. Third-party requests
Some pages load placeholder photographs from a third-party image service. That service does not set cookies through our pages, but as with any external request it receives the standard information your browser sends to any host — IP address, user-agent and referring URL. If you block third-party requests at the browser or network level, those images will not load; nothing else on the site depends on them.
5. Turning cookies off in your browser
Every major browser lets you block or delete cookies and site storage. Blocking all cookies may break parts of this and other sites, so per-site controls are usually the better choice.
- Chrome: Settings → Privacy and security → Third-party cookies, and Settings → Privacy and security → Site settings → View permissions and data stored across sites to remove data for a single site.
- Firefox: Settings → Privacy & Security → Cookies and Site Data → Manage Data, or use Enhanced Tracking Protection for per-site control.
- Safari (macOS): Safari → Settings → Privacy → Manage Website Data. On iOS: Settings → Safari → Advanced → Website Data.
- Edge: Settings → Cookies and site permissions → Manage and delete cookies and site data.
Most browsers also offer a private or incognito window, which discards cookies and storage when the window closes. General, vendor-neutral guidance on cookie controls is published by the Information Commissioner's Office.
6. Do Not Track and Global Privacy Control
We honour the Global Privacy Control signal where a browser or extension sends it: when GPC is present we treat the analytics and functional categories as declined, regardless of any earlier banner choice. The older Do Not Track header is not a consent mechanism under UK or EU law, but because we set no advertising cookies at all, no additional action is needed when it is present.
7. Changes and contact
If we add, remove or change a cookie, this page is updated before the change goes live and the date at the top is revised. Questions about anything listed here can go to [email protected], or by post to Bundlesqubly Digital Labs Ltd, Unit 7, Kestrel Works, 128 Bermondsey Street, London SE1 3TX. Broader detail about how we handle personal data is in the Privacy Policy.
