Cookies and local storage

Last updated: 5 July 2026

In short

Reactive uses no tracking or profiling cookies and therefore needs no cookie consent banner. We do not profile you and we do not share data with advertising networks.

What we use, and why

No profiling cookies

We set no cookies for advertising, remarketing or cross-site tracking. Site statistics are collected with Pirsch Analytics, a cookieless tool: it stores no identifiers on your device and produces only aggregate, anonymous data. See the Privacy Policy.

Local storage (localStorage) — technical, essential

The application saves some information in your browser’s local storage (localStorage). This storage is not a cookie, is not sent to servers with every request, and is not used to track you: it exists solely to make the app work on your device. In particular it holds:

• your apps’ data (items, form values, calculations);
• your saved document library;
• your preferences (theme, interface language, settings);
• if you enable synchronisation, your local profile (name and colour) and related configuration.

As storage strictly necessary to deliver the service you requested, it is not subject to prior consent.

How to clear it

You have full control over this data. You can delete it at any time:

• from your browser settings, by clearing “site data” / “local storage” for the app’s domain;
• or by deleting individual apps from the library inside the application.

Clearing local storage removes your apps’ data irreversibly.

Third-party technical cookies

The technical libraries loaded from public CDNs (jsDelivr, unpkg) serve only static code and set no profiling cookies. Any technical infrastructure cookies from those networks serve solely content delivery and security purposes.
