Keepstone is your private offline diary for photos, voice notes and letters to your future self. Capture a moment now, seal it until a date you choose, and return to it when the time comes. WRITE IN YOUR OWN WAY Create memories with rich text, up to 10 photos, and voice notes. Organize entries with tags and choose the themes and typography that make your diary feel like yours. LET TIME KEEP A SECRET Seal a memory or letter until a date you choose. Its content stays hidden in the app until that date, while its title helps you recognize it in the Vault. Previously sealed memories show their unlock date once opened. Protect access to the Vault with Face ID or Touch ID on supported devices. BACK UP AND SHARE Export your diary as an encrypted, password-protected .kstone file. Keep a copy somewhere safe or share an individual memory with someone you trust. Imported shared memories remain read-only, and sealed copies keep their opening date. YOUR JOURNAL, ON YOUR DEVICE No account is needed for journaling. Your memories are stored locally, and writing and reading work offline. Keepstone does not automatically sync your diary between devices. Export a backup before changing devices or uninstalling the app, and keep its password safe. OPTIONAL SUPPORTER FEATURES A one-time Supporter purchase unlocks additional themes, typography, detailed journal statistics, and PDF export for open memories. Voice recordings remain playable in Keepstone and are not embedded in PDFs. No subscription is required. Available in English, Spanish, French, Japanese, Simplified Chinese, and Portuguese.
