Supporting text:
Import any file — PDFs, photos, videos, documents, archives — and SecureVault encrypts it with AES-GCM 256 before storing it locally. Face ID locks the vault so only you can open it. Your files never leave your device. No cloud uploads. No third-party servers. Just encryption that works, silently in the background.
2. Problem
Your phone holds your most sensitive files: a scan of your passport, a signed contract, a salary slip, an NDA from work, a video draft you haven't published yet.
The Files app keeps them visible to anyone who picks up your phone. Email attachments and chat messages store copies on remote servers you don't control. Cloud drives hold your data on someone else's infrastructure — one breach, one subpoena, one shared link, and your private documents are no longer private.
Dedicated encryption apps are either too complex (GPG keys, manual encryption workflows) or too expensive (enterprise suites charging $30/month for features you'll never use). The ones that do offer simple encryption often upload your files to the cloud "for sync" — defeating the entire purpose.
You don't need a cloud. You need a safe. A digital safe on your own device, opened only by your face, holding only what you put in it.
3. Solution
- AES-GCM 256 encryption — Military-grade encryption, applied automatically to every file you import. Each file gets its own unique encryption key. CryptoKit powers the encryption entirely on-device using the Secure Enclave. No passphrase to remember, no key file to lose.
- Face ID lock — The vault stays locked until you authenticate with Face ID or Touch ID. Close the app? It locks. Walk away? It locks. Hand your phone to a child? Locked. Your files are visible only to you, and only when you're holding the phone.
- Import any file format — PDFs, Microsoft Office documents, photos, videos, zip archives, audio files, code files — if iOS can read it, SecureVault can import it. Use the system document picker to grab files from Files app, or import directly from your Photos library.
- Folder organization — Create folders, nest them, rename them, move files between them. Your vault can be as organized as your desktop — or as messy as a junk drawer, your choice.
- QuickLook preview — Tap a file to preview it instantly with iOS QuickLook, no need to decrypt and export. View PDFs page by page, play videos, read documents, inspect images — all within the vault. Decryption happens on-the-fly and the temporary file is wiped immediately after you close the viewer.
- Secure file deletion — When you delete a file from SecureVault, the encrypted data is overwritten 3 times before deletion. File recovery tools cannot resurrect it. Gone means gone.
- File details & metadata — Every file shows its type, size, import date, and encryption algorithm. Full transparency into what's stored and how it's protected.
- Search & tags — Find files by name instantly. Tag files with custom labels and filter by tag. Organize without moving things around.
4. How It Works
Step 1 — Authenticate. Open SecureVault. Face ID or Touch ID scans instantly. The vault unlocks for you and only you.
Step 2 — Import files. Tap the import button. Choose files from Files app, Photos, or any document provider. SecureVault encrypts each file with AES-GCM 256 before saving it to the vault. The original file stays in place — the encrypted copy lives inside the vault.
Step 3 — Organize & access. Browse your vault by folder, tag, or search. Tap any file to preview it with QuickLook. The decryption and cleanup happen automatically — you never see the raw unencrypted file sitting on disk.
Step 4 — Secure deletion when done. Swipe to delete a file. Three overwrite passes ensure the encrypted data is irrecoverable. Need to export? Share via the iOS share sheet — the decrypted file is delivered to your chosen destination and cleaned up after.
5. Privacy & Security
All encryption happens on your device. Not on a server. Not in the cloud. In the Secure Enclave of your iPhone's A-series or M-series chip.
What SecureVault does:
- Encrypts every imported file with AES-GCM 256 (CryptoKit)
- Stores encrypted files in the app's sandbox — inaccessible to other apps
- Locks the vault behind Face ID / Touch ID
- Overwrites deleted data 3 times before removal
- Cleans up temporary decrypted files immediately after viewing
What SecureVault does NOT do:
- Upload files to any cloud server
- Sync data across devices
- Collect analytics or usage data
- Require an account, email, or phone number
- Send telemetry or crash reports
- Include third-party SDKs that track you
- Store encryption keys on any server
Permissions requested:
- Face ID / Touch ID — to unlock the vault
- Files & Photos (read) — to import files
- Files & Photos (write) — if you choose to export or share
Verifiable privacy:
Put your iPhone in Airplane Mode. SecureVault works identically. Every encryption, preview, search, and delete operation runs locally with zero network dependency. Network traffic is trivially verifiable — there is no "sync later" catch, no deferred upload, no delayed phone-home.
6. Who It's For
| User | Pain point | How SecureVault helps |
|---|---|---|
| 🔏 **Privacy-minded individual** | "I need to store scans of my passport, ID card, and tax documents somewhere safe." | SecureVault encrypts every document with AES-GCM 256 and locks them behind Face ID. Your most sensitive personal files stay on your device, not in a cloud folder shared with who-knows-what. |
| 💼 **Professional / Employee** | "My company sends salary slips and NDAs as PDFs. I can't store these on a cloud service." | Import payroll PDFs, signed NDAs, confidentiality agreements, and HR documents. They stay encrypted and local. Share them via the share sheet only when you need to — no accidental cloud sync. |
| 👶 **Parent** | "I keep digital copies of my kids' birth certificates, school records, and medical forms." | Scan or import important family documents. Organize them by child or by type in folders. QuickLook previews mean you can find and show the right document in seconds. |
| 🎨 **Creator** | "I have unreleased designs, video drafts, and project files I don't want leaked." | Store WIP creative assets in an encrypted vault. Share specific files when ready. Delete drafts securely — three overwrites ensure scrapped work stays scrapped. |
7. Pricing
Simple one-time purchase. No subscriptions, no hidden tiers, no "enterprise" nonsense.
| Plan | Price | What You Get |
|---|---|---|
| **SecureVault** | **¥18** one-time | Full app: AES-GCM 256 encryption, Face ID lock, unlimited imports, folder organization, QuickLook preview, search & tags, secure deletion, all future updates |

9. FAQ
Q1: Can SecureVault read my encrypted files?
A: No. Encryption keys are derived on your device and stored in the iOS Keychain. Not even the app developers can decrypt your files. The source code is verifiable — the encryption path uses standard CryptoKit AES.GCM with no backdoor, no telemetry, and no data egress.
Q2: What happens if I delete SecureVault?
A: All encrypted files stored in the app sandbox are removed when you delete the app. If you want to keep your files, export them before deletion — they will be decrypted during export.
Q3: Can I back up my vault?
A: SecureVault is designed for local-only storage. Your encrypted files stay on your device. If you need a copy, export individual files or use iOS device backup (encrypted iTunes/Finder backup will include the app sandbox data).
Q4: Does SecureVault work offline?
A: Yes. Everything works offline — encryption, decryption, preview, import, export. There is no internet dependency at all.
Q5: What file formats are supported?
A: Any file format iOS can read: PDF, DOCX, XLSX, PPTX, TXT, RTF, JPG, PNG, HEIC, MP4, MOV, MP3, M4A, ZIP, and hundreds more. If iOS can open it in QuickLook, SecureVault can import and encrypt it.
Q6: How is this different from just using a password-protected Notes folder?
A: iOS Notes only supports text, images, and a few attachment types. SecureVault handles any file format, applies AES-GCM 256 encryption (not just Notes' device-level encryption), provides folder organization, search, tags, secure deletion with overwrite, and full file metadata.
Q7: Is there an Android or Mac version?
A: Currently iPhone only. A Mac (Apple Silicon) version is under consideration.
