How 1Loom works

Small, focused apps — built carefully, described honestly.

01

On your device first

OpenNote and Connections keep what you create on your phone. The developer has no access to your notes or contacts.

02

Plain-language privacy

Each released app has its own privacy policy that spells out what it does and doesn’t collect.

03

Honest status

Live, in development or proof of concept — every app says exactly where it stands.
