Note: The analytics details (2.2, 4, 6) are new and are currently being reviewed by our lawyer.
This Cookie Policy explains how Ulifyi KLG uses cookies and similar technologies on uli.fyi, ulifyi.ch, and related Ulifyi web services (together, the “Services”).
For more information about personal data processing, see our Privacy Policy.
1. What are cookies?
Cookies are small text files stored on your device by your browser. Similar technologies include local storage, session storage, pixels/tags, and comparable identifiers.
2. Cookie categories we use
2.1 Strictly necessary cookies (Essential)
These cookies are required for the Services to function. Without them, core functions such as login, security, and session management cannot work.
Examples on Ulifyi:
- Authentication/session cookies (our own cookies / “SIDs”) for login, session management, and protection against unauthorized access
- Security cookies (e.g., CSRF protection, abuse prevention)
ulifyi_cookie_consent_v1: stores your cookie choice for all services under uli.fyi (180 days)
Legal basis: Legitimate interests / necessity to provide the service (depending on applicable law).
2.2 Analytics / measurement cookies
These cookies help us understand how the Services are used (e.g., pages/features used, performance, errors) so we can improve them.
On Ulifyi: only our own usage analytics, without third parties (see Section 4).
ulifyi_aid: random browser ID, 180 days from the last visit, for all services under uli.fyi- sessionStorage
ulifyi_ua_sid: ID of the open tab, until the tab is closed - sessionStorage
_ulifyi_sid/_ulifyi_attr(Ulifyi Insights on uli.fyi): tab ID and campaign parameters, until the tab is closed
Consent: We set these analytics IDs only once you allow "Analytics". Without consent we store nothing on your device for this.
2.3 Marketing cookies
Ulifyi currently does not use marketing cookies for personalized advertising. If this changes, we will update this Cookie Policy and (where required) ask for consent.
3. Cloudflare (DNS/CDN/Security)
We use Cloudflare for DNS and to help secure and optimize the Services (e.g., DDoS protection, caching, traffic filtering).
Cloudflare may set cookies or use similar technologies to provide security features (e.g., bot protection) and processes technical data such as IP address, request headers, timestamps, and requested resources.
- Cloudflare Privacy Policy: https://www.cloudflare.com/privacypolicy/
4. Our own usage analytics
With your consent we measure ourselves which pages and buttons are used, which form fields are reached (never what you type), how far you scroll and which variant of an A/B test you see. The data stays on our servers, without third parties. When you are signed in we link it pseudonymously to your account. Details, legal bases and objection: Privacy Policy, Section 9.
We no longer use Google Analytics or Google Tag Manager.
5. Our authentication/session cookies (“SIDs”)
To run Ulifyi securely, we use our own session and authentication cookies (e.g., “SID” or similar tokens). These are necessary to:
- log you in and keep you logged in,
- manage your session,
- implement security features (e.g., CSRF protection, abuse detection),
- store settings required for core operation.
These cookies are essential and cannot be turned off via the cookie banner without breaking login and core functionality.
6. Retention / duration
We use both session cookies (deleted when you close your browser) and cookies with a limited lifetime.
- Essential auth/session cookies: duration depends on your security and session configuration
ulifyi_cookie_consent_v1: 180 daysulifyi_aid(analytics): 180 days from the last visit- sessionStorage IDs (analytics): until the tab is closed
- The measured events themselves are deleted after 90 days.
7. Consent & cookie settings
In the EU/EEA and Germany, optional cookies (e.g., analytics) typically require prior consent. You can change or withdraw your choice anytime via “Cookie settings” (e.g., a footer link).
8. How to delete or block cookies
You can manage cookies in your browser settings:
- delete existing cookies
- block cookies (all or certain categories)
- configure notifications when cookies are set
Note: If you block essential cookies, login and core features may not work reliably.
