CLUSTER ENTRIES-FOLDERS-OFFLINE · 15 ENTRIES · EARLIEST ENTRY 2026-04-23
Offline encrypted note-taking apps
This cluster consists of offline note-taking applications that emphasize on-device encryption, password protection, and organizational features such as folders, tags, and visual mind-map canvases. The dated history shows a sparse, intermittent pattern with single entries in 2017, 2024, 2025, and early 2026, offering no sustained trend. Traction leaders are CipherNotes, CypherLeaf, and NotePad, all tied at zero stars.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
