Description by Pablo Silva(from the App Store)
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.
Each subscription will automatically renew 3 days before the expiration date for
the same time period. Subscriptions can be cancelled at any time before the renewal.
