Description
Keepstone is a private journal for memories you want to preserve, seal, and rediscover later.
Write a memory, add photos or voice notes, lock it until a future date, or create a letter to your future self. Your journal stays local on your device: no account, no cloud sync, no social feed.
WRITE
Capture daily thoughts, meaningful moments, photos, and voice notes in a calm writing space.
SEAL
Lock memories until a future date. Create personal time capsules or letters to your future self.
ORGANIZE
Use tags, search, themes, typography, and journal statistics to shape your archive over time.
EXPORT
Create password-protected .kstone files, encrypted backups, and PDF exports for unlocked memories.
PRIVATE BY DESIGN
Your data stays local on your device. Keepstone does not require an account to write, seal, import, export, or read your memories.
SUPPORTER
Keepstone includes an optional one-time Supporter upgrade for premium themes, typography, full journal statistics, and PDF export.
Keepstone is built for memory, privacy, and time.
What's new (v1.7.7)
Keepstone 1.7.7 refines the experience around privacy, speed, and appearance.
Amethyst now follows your system appearance automatically: Amethyst Light in Light Mode, and the classic dark Amethyst experience in Dark Mode.
Every free theme now includes a light version, and Moonstone joins as a new premium theme.
Startup is faster for journals with audio memories by avoiding unnecessary audio loading at launch.
Vault alerts make upcoming sealed-memory unlocks easier to notice, while encrypted .kstone sharing, sealed-memory titles, and read-only imported memories remain intact.
