Swatch
Privacy
Last updated: 17 June 2026
Swatch is a free, in-browser colour tool operated by Lars Holmström, an independent developer in Melbourne, Australia (larsh.dev). The short version: no account, no cookies, and nothing that identifies you personally.
The short version
- No accounts, no sign-up, and no email needed to use Swatch.
- No cookies and nothing stored on your device.
- We use privacy-respecting product analytics (PostHog) to understand how the tool is used, in aggregate.
- If your browser sends a Do Not Track signal, no analytics or session recording loads at all.
- We never sell your data, and there is no advertising.
What we collect
When Do Not Track is not set, Swatch loads PostHog, a product-analytics service, which records:
- Usage analytics — which features you use, clicks, scrolls and navigation, the site that referred you, and general device information (browser and operating system type, screen size, language).
- Session replay — a reconstruction of how you interacted with the page: a synthetic playback of what you clicked, where you moved, and what changed on screen. It is not a video or screen recording of your device, and text typed into any field is masked by default and not captured.
- Approximate location — PostHog uses your IP address to estimate a coarse location (country, sometimes region or city). We use this only in aggregate, and your IP address is not used to identify you.
We do not collect names, email addresses, passwords, or payment details, because Swatch has no accounts and asks for none of those.
Cookies and on-device storage
Swatch is cookieless. Analytics run with memory-only persistence, which means no cookies and nothing written to your browser's storage. Nothing about your visit persists on your device or links one visit to the next — reload the page and you are a brand-new anonymous session.
Palettes you build live only in the page while it is open, and exports are generated entirely in your browser.
Do Not Track
We honour the Do Not Track (DNT) browser signal. If DNT is enabled, Swatch loads no analytics and records no sessions — you use the tool with zero measurement.
Where your data goes
Analytics are processed by PostHog Inc. on its United States cloud, acting as our data processor. If you use Swatch from outside the US (including Australia, the EU and the UK), anonymous usage data is transferred to and processed in the United States.
The site itself is served as static files by our hosting provider, which may keep standard server logs (such as IP address and browser type) for security and reliability. We use no other third-party services, trackers, or advertising networks.
How long it is kept
Usage and session-replay data are retained by PostHog under our account's retention settings and then deleted. Because nothing is linked to an identifiable person, individual records cannot be tied back to you.
Your rights
Depending on where you live — for example under the Australian Privacy Act, the EU/UK GDPR, or the California CCPA — you have rights over personal data about you, such as access, correction, and deletion. Because Swatch is anonymous and cookieless, we usually hold no information that can be connected to you individually. If you have a question or request, email us and we will help where we can.
Children
Swatch is not directed at children under 13, and we do not knowingly collect information from them.
Changes
If this policy changes, we will update this page and the date above. Material changes will be reflected here.
