Cookie policy

Last reviewed: 2026-04-28. This policy supplements our privacy policy.

1. We use cookies sparingly

We use as few cookies as possible. There are no advertising cookies, no third-party tracking pixels, no social-media buttons that send data to platforms.

2. Which cookies we set

2.1 Necessary cookies (always on)

These cookies are technically required for the website to work. They cannot be disabled — without them the site doesn't function correctly.

psf_consent
Stores your cookie decision (necessary + optionally analytics). First-party cookie. Retention: 365 days. Content: version identifier + list of accepted categories.

2.2 Analytics snippet (opt-in, cookieless)

We use Cloudflare Web Analytics — cookieless and aggregate-only. No analytics cookies are set. If you consent in the cookie banner, we load a small script that reports anonymised page-views to Cloudflare (country, device class, referrer — no per-visitor profile, no cross-site tracking). You can withdraw consent at any time by clicking "Only necessary" in the banner.

Cloudflare Web Analytics
Helps us understand which pages of our website are visited — cookieless, aggregate, EU-resident. Cloudflare runs in the same EU jurisdiction as our Workers backend. Aggregate retention: 6 months (Cloudflare default). Cookies: none.

3. What we don't set

4. How to change your consent

Use the cookie banner at the bottom of the page to adjust your decision at any time. If you don't see the banner, you've already made a decision — delete the psf_consent cookie in your browser to see the banner again.

Browser-specific guides:

5. Cookies in the mobile app

The mobile app (iOS / Android) does not use cookies — it uses the platform-specific storage (UserDefaults / SharedPreferences) instead, for your settings. This storage stays on your device and is not transmitted to us.

The mobile app contains no third-party SDK for crash reporting or product analytics. Mobile crashes are captured on-platform by Apple App Store Connect and Google Play Vitals — we read them as developer reports; they don't pass through our servers. App usage is not measured at v1.0.

6. Changes to this policy

If we add or change cookies, we update this policy and the cookie banner appears again so you can make your decision afresh. Earlier versions are visible in the public version history of the repository.
