SecDocKeeper

Keep your most sensitive documents secure, local, and strictly in your hands. SecDockKeeper is a local-first, end-to-end encrypted vault designed for the files you cannot afford to lose or leak. Whether it's your passport, medical records, tax forms, or confidential contracts, SecDockKeeper ensures your data stays firmly on your device. There are no accounts to create, no cloud servers to trust, and absolutely zero telemetry. IMPORTANT: Your vault is secured by a master password known only to you. If you lose your password, no oneβ€”not even usβ€”can recover your data. CORE FEATURES Military-Grade Encryption: Your master password derives a 256-bit key on the device using Argon2id. Every single document gets its own AES-256-GCM data key (envelope encryption). Smart On-Device OCR: Automatically scan and tag imported images (like passports, IDs, and invoices). All text recognition happens entirely locally, meaning your data never leaves your phone. Total Organization: Group your documents into folders, apply color-coded tags, and filter with a single tap. All metadata, names, tags, and full-text search indexes are secured inside a locked SQLCipher database. Hidden "Stealth" Tags: Need plausible deniability? Create hidden tags that are stored only as HMAC hashes. They are entirely invisible in lists and autocomplete, revealing their linked documents only when you type the exact tag name into the search bar. Secure Split-Sharing: Safely share individual documents. Export a file as an encrypted .sdkblob and a separate .sdkkey.json. Send the file over one channel and the key over another for maximum security. Portable Offline Backups: Export your entire vault as a single, fully encrypted archive (blobs and database only, no key material). Easily restore it on a new device using your original master password. Biometric Convenience: Quickly unlock your vault using Face ID or Touch ID. Your master password remains safely sealed in your device’s platform keychain. Anti-Snoop Defaults: The app immediately auto-locks when sent to the background. Decrypted plaintext is strictly short-lived, and temporary viewing directories are automatically wiped every time the vault locks. ABSOLUTE PRIVACY We believe privacy is a default, not a feature. SecDockKeeper contains absolutely zero analytics and no third-party SDKs in the hot path. There are no network calls for document handling. The only journey your files take is from your device's file picker directly into your encrypted, on-device vault. OPEN SOURCE & AUDITABLE Trust requires transparency. SecDockKeeper is 100% open source under the Apache 2.0 license. Our cryptography, database schema, and import paths are fully auditable by anyone.

About

Rainy Days Scheduler

Read full description

Keep a backup venue, contact and decision deadline beside an event, then record a reviewed change to an indoor plan. HOW IT WORKS 1. Open Plan B Desk, choose an eligible event and record the backup venue, contact and decision time. 2. Confirm the backup and review the forecast context, including stale or missing data. 3. Apply the decision to the event and retain the original details for guarded restoration. Event scheduling remains available. Editing an event preserves its completion and outcome records; unreadable event data is preserved. WHAT TO KNOW Applies to eligible nonrecurring, uncompleted events. You must confirm availability and tell attendees yourself. Forecasts are not guarantees. For lightning, use a substantial building or appropriate enclosed vehicle; tents and picnic shelters are not safe shelter. iPhone and iPad.
