Analytics

This page describes the audience measurement data collected when you browse arkflow.ch. It supplements the privacy policy and gives you direct control (opt-out) over analytics tracking.

1. What we collect

Two subsystems run in parallel, both hosted in the European Union:

  • Umami (analytics.ark.swiss) — traffic measurement: page views, referrers, countries, device type. No cookies, no persistent identifier. IPs are irreversibly hashed.
  • ark.analytics (app.ark.swiss) — conversion measurement: CTA clicks, signup wizard progression, Stripe payments. Uses an anonymous technical identifier (visitor_id) stored in localStorage, not shared with other sites.

No personal data (email, name, address) is transmitted to these tools. Emails entered in forms never leave our business database.

2. Purposes

  • Measure traffic and identify useful content
  • Diagnose friction points in the signup funnel
  • Understand acquisition channels (organic, AI, social, direct)

3. Legal basis

Legitimate interest (GDPR art. 6.1.f / FADP art. 31(2)(e)) for the cookie-free Umami layer. For ark.analytics, the localStorage storage is strictly functional (no cross-site profiling, no third-party sharing) and therefore falls under the "strictly necessary" exception (ePrivacy art. 5.3).

4. Retention

  • Visit events and first-visit origin in the central system: 13 months, then deleted automatically
  • Signup origin, when a form is submitted: 24 months
  • Weekly/monthly aggregates: kept anonymised without limit
  • visitor_id (ark_vid): stays in your browser until you clear it, which you can do at any time

5. Recipients and transfers

No data is transmitted to third parties. These analytics tools are hosted in the European Union.

6. Your rights

You have the rights of access, rectification, erasure, objection and portability. Contact: privacy@ark.swiss.

7. Opt out

You can disable analytics tracking at any time from this browser. The preference is stored locally (no network request needed).
