Do you need an easy and fast address book?
Elencus is designed to be intuitive and immediate. No complicated configurations, no endless menus. Open the app, search for the contact, find it instantly. Everything else is automatic: local backup, instant saving, clean interface. You can focus on work, not on the tool.
Do you like using a tool without registration and without paying a subscription?
Elencus is completely free. It requires no registration, account, or login. There are no hidden premium plans or artificial limits: install the PWA from your browser, use it, done. The core of the project stays free and accessible to everyone.
Do you care about your privacy?
Elencus was born with a fundamental principle: your data is yours alone. We don't use servers, we don't collect statistics, we don't track anything. Everything is saved locally on your device. Nobody, not even us developers, can see or access your contacts. It's privacy by design, not a promise: technically impossible to violate.
Want to know how Elencus works?
The heart of the Elencus application is its advanced and intelligent search system. You can quickly find any contact starting from generic and minimal information: a name, an organization, part of an email. Combined search (AND) allows you to filter precisely. The triple backup system (LocalStorage, IndexedDB, JSON export) ensures your data is always safe. Multi-format import supports CSV, JSON, TXT and standard formats like Google Contacts and Outlook. You can export everything to CSV, JSON or PDF to share or migrate. Automatic duplicate detection keeps your address book clean. Everything works offline, always.
