About

Secret Notes

Read full description

Trove is where your private thoughts live behind real encryption. Every note is locked with AES-256 — the same standard trusted by security professionals. Your password is never stored, never synced, never seen by anyone. It lives only in your head. Forget it, and not even we can open the note. That is the whole point. WHY TROVE • AES-256 encryption with 600,000-round key strengthening • Your password is never saved to disk, to iCloud, or to our servers • The note list and encrypted text stay visible without a password — decryption happens only in memory, only when you ask • No account, no sign-up, no tracking, no ads ONE ENCRYPTED LOCKBOX FOR EVERYTHING Bank details, passwords, a private journal, a secret diary, login codes, confidential ideas, a quick brain dump — keep your whole stash in one secure vault. FEATURES • Encrypted notes, private journal and secure diary in one app • Voice dictation — speak your notes, transcribed on-device (audio never leaves your iPhone) • Color tags to organize and archive your notes • Optional iCloud sync — your encrypted vault follows you across iPhones and survives reinstalls • Local-only mode if you prefer nothing ever leaves the device • Share an encrypted note with a friend over any channel — only someone with the password can open it • Search by title or date • Clean, fast, forced dark mode SHARING Send an encrypted note to anyone — over Messages, Mail, AirDrop, any channel. Share the password separately... Only the person who knows it can open the note, so it stays safe even if the channel is not... PRIVACY BY DESIGN Trove cannot read your notes. There is no backdoor, no recovery, no hint. Strong encryption means only you hold the key. We collect nothing about your content — what you write stays yours. DISCLAIMER Application cannot add photos, videos to notes by decision of developer. Trove is for text only — by design. Encrypted media is intentionally not supported to keep the app safe and simple PREMIUM Unlock unlimited notes, sharing, importing and more: • Weekly or Monthly plan • 3-day free trial for new subscribers • Cancel anytime in your Apple ID settings Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period. Your Apple ID account is charged for renewal within 24 hours prior to the end of the current period. Any unused portion of a free trial is forfeited when you purchase a subscription. Manage or cancel your subscription in your Apple ID account settings after purchase. Your secrets deserve a real lock. Keep them in Trove.
