Velle

About

Velle is a period tracker designed with your privacy as the top priority. Unlike most apps that sell user data, Velle keeps your information completely private with its offline-first, zero-knowledge design. There are no accounts, no cloud storage, and no advertisements. Key features include local encryption to ensure your data remains on your device, a burner PIN for immediate data removal, and a stealth mode that disguises the app icon. You can also export your data as raw CSVs or clinician-ready PDFs. Your cycle data remains private, inaccessible to tech companies, the app developers, or anyone else who might access your phone. You are in complete control of your cycle information.
