Secretly: Secure Messenger

Secretly is a private messenger that needs no phone number and no email. Your account is a cryptographic key created on your device, and you get a random Secretly ID — nothing that ties your account to your name or your SIM card.

NO PHONE NUMBER. NO EMAIL.
• Create an account in seconds — no SIM card, no email, no personal details
• Add contacts by Secretly ID, QR code or profile link
• Your address book is never uploaded
• Messages from people you don't know arrive as requests — you decide who can reach you

END-TO-END ENCRYPTION
• Messages, voice messages and files in private and group chats are end-to-end encrypted with the Double Ratchet algorithm, which provides forward secrecy
• One-to-one voice and video calls are end-to-end encrypted
• Verify a contact in person by scanning their QR code or comparing security codes; Secretly warns you when a contact's keys change
• Your chat database is encrypted on your device

YOU DECIDE WHO SEES WHAT
• Choose who can see your last-seen time, profile photo and forwarded messages, and who can call you: everyone, your contacts or nobody
• Auto-delete messages in any chat after 24 hours, 7 days or 30 days
• Lock Secretly with a password, a pattern or Face ID / Touch ID
• Keep private conversations in a separately locked "Personal" section
• Hide chat content in the app switcher
• Delete your account at any time, or let it delete itself after a period of inactivity you choose

EVERYTHING YOU EXPECT FROM A MESSENGER
• Groups with admins and moderators, invite links, @mentions and pinned messages
• Group voice and video calls
• Replies, reactions, editing, delete for everyone, forwarding and search
• Scheduled and silent messages, chat folders
• Voice messages, photos, videos and files
• Stickers, including a sticker maker that cuts the subject out of your photo on the device (iOS 17 or later)
• Link previews are created by the sender, so your device doesn't fetch links you receive
• On-device message translation
• Encrypted backups protected by your password, plus a recovery kit to restore your account
• A Mac app, linked to your iPhone with a QR code

OPEN AND HONEST
• No ads, no analytics or advertising SDKs
• Open source under AGPL-3.0 — anyone can review the code on GitHub
• We publish a threat model listing what Secretly protects against and its known limitations
• An independent security audit has not been completed yet — we'd rather tell you than let you assume

SECRETLY PREMIUM
Secretly is free. Premium is optional and adds voice-message transcription on your device, larger files, bigger groups and group calls, premium sticker packs, and personalisation: themes, accent colours, animated wallpapers, avatar frames, profile covers, app icons and ringtones. Security features are never part of Premium.

Premium is available as a monthly or yearly auto-renewing subscription, or as a one-time lifetime purchase. Payment is charged to your Apple Account when you confirm the purchase. A subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. You can manage or cancel subscriptions in your App Store account settings. Any unused part of a free trial is forfeited when you buy a subscription.

Secretly works only between Secretly users. It does not send SMS or MMS and does not call phone numbers.
