Lock it away
Pick a contact. It’s encrypted on your device and removed from your address book — photo, addresses, everything preserved inside the vault. Out of sight, out of autocomplete.
Contact Vault for iPhone
The pause is the point.
Some numbers you shouldn’t delete — you just shouldn’t be able to text them at 1 a.m. The ex. The old dealer. The rep who has your card on file. Contact Vault seals them behind a cooling-off timer you choose, then hands them back once you’ve had time to think.
No account. No cloud. Nothing leaves your phone.

How it works
No willpower required at the moment you have the least of it.
Ask, then wait
Want back in? Request access and a timer starts — anywhere from minutes to a week. You set it. No confirmation dialogs, no “are you sure?” The wait is the safeguard.
Briefly unlocked
When time’s up, you get a short window: see the details, message or call directly, or restore the contact for good. Then the vault closes itself again.
Why it works
A speed bump, not a wall
You always get access eventually. Just not instantly — and that’s the whole trick.
A timer you can’t sweet-talk
Decide to shorten a wait? That change waits out the current delay first. Timers already running never shrink. Past-you stays in charge.
Sealed on your iPhone
AES-256 encryption via Apple’s CryptoKit, with the key stored in your device Keychain. No servers involved — because there are no servers.
Full-fidelity restore
Photo, numbers, emails, addresses, birthday — everything comes back exactly as it went in. (Except Notes; Apple keeps that field off-limits.)
Reach out without restoring
In an unlock window you can message or call right from the app. The contact never has to re-enter your address book.
Locks itself behind you
The viewing window is short and closes on its own. No cleanup, no “lock it back” chore, no lingering temptation.
Know the moment it opens
A notification arrives the second your wait is up. No checking, no watching the clock — that’s the timer’s job.
No accounts. No cloud. No analytics.
Contact Vault doesn’t have a backend. Not “a secure backend” — none. Your contacts are encrypted at rest with AES-GCM (256-bit, via Apple’s CryptoKit), the key is stored in your iPhone’s Keychain, and the encrypted data never travels anywhere. We can’t read your vault, lose it, or sell it. We never see it.
The privacy policy, in full
Contact Vault collects no personal data. No contacts, no usage data, no identifiers, no crash reports, no analytics of any kind. The app requests Contacts permission solely to move the contacts you choose into your on-device vault, and notification permission solely to tell you when a timer ends. It makes no network connections and contains no third-party SDKs, ads, or trackers. If this policy ever changes, this page changes first — but the plan is for it to stay exactly this short.

FAQ
Fair questions
Is my data actually safe?
It never leaves your phone, so the usual worries don’t apply. Contacts are encrypted with AES-256-GCM using Apple’s CryptoKit; the key lives in your iOS Keychain. There’s no account, no sync, no server — nothing to breach. One honest caveat: delete the app and the vault goes with it, so restore anyone you want to keep first.
What if I genuinely need someone during a wait I set?
Then you wait — there’s no override, because the whole point is that there’s no override. But you pick every delay, so be honest when you set it: minutes for the impulse purchases, longer for the people who cost you more. Emergencies deserve thought too, and someone you might truly need in one probably doesn’t belong in a vault. This app is for the contacts you’ve already decided need distance.
Can I get a contact back permanently?
Yes, always. Every unlock window includes a Restore option that returns the contact to your address book exactly as it was and clears it from the vault. Contact Vault is a speed bump, not a wall — you always get through eventually.
Does locking someone delete our message history?
No. iOS doesn’t let apps touch your Messages — and we wouldn’t want to. Removing the contact card just un-names the conversation, so the old thread shows a bare phone number instead of a name. Which, honestly, helps.
Is anything not preserved?
One field: Notes. Apple restricts apps’ access to a contact’s Notes, so whatever you wrote there doesn’t make the round trip. Everything else — photo, numbers, emails, addresses, birthdays, company — comes back untouched.
