Cookie Notice
A short description of the strictly necessary cookies that keep authentication and the application session working — and our commitment that nothing more is set without your explicit consent.
This Cookie Notice explains how we use cookies and similar storage mechanisms on the Service. It supplements our Privacy Policy.
1. What cookies we use
We use only strictly necessary cookies and local storage required for the Service to function. These items cannot be switched off in our systems without breaking core functionality. Under Polish telecommunications law (Art. 173 of the Telecommunications Law, implementing the ePrivacy Directive), strictly necessary storage does not require prior consent.
We do not use:
- analytics cookies (no Google Analytics, no Plausible, no Umami),
- advertising or marketing cookies (no Meta Pixel, no Google Ads, no LinkedIn Insight),
- social media tracking cookies,
- heatmap or session-replay tools.
For this reason no cookie consent banner is shown on the Service.
2. Specifically, the items we set
| Item | Type | Purpose | Set by | Approximate lifetime |
|---|---|---|---|---|
| Authentication session token | HTTP cookie / local storage | Keeps you signed in between requests; required for the application to work | Supabase Auth (our authentication provider) | Up to the duration of the session, refreshed as configured by the auth provider; cleared on sign-out |
| CSRF / security tokens | HTTP cookie | Protects forms and authenticated requests against cross-site request forgery | Our application | Session |
| Hosting platform cookies (where applicable) | HTTP cookie | Routing, load balancing, security on Vercel’s edge | Vercel | Short-lived, technical |
The exact names and lifetimes set by Supabase and Vercel may change as those providers update their software. Refer to:
- Supabase documentation: https://supabase.com/docs,
- Vercel documentation: https://vercel.com/docs.
3. How to control cookies in your browser
All major browsers let you view, restrict or delete cookies and local storage. Note that blocking strictly necessary items will prevent you from signing in and using the Service.

4. Changes to this Cookie Notice
If we ever introduce non-essential cookies (for example analytics), we will:
- update this Cookie Notice,
- introduce a cookie consent banner that asks for your prior, freely given, granular consent in line with the GDPR and ePrivacy rules,
- block such cookies until consent is given.
We will not silently start setting non-essential cookies.
