clipLogger: Secure, Lightweight Clipboard History ManagerIn an age where productivity tools are measured by how unobtrusively they fit into your workflow, clipLogger aims to strike a harmonious balance between simplicity, privacy, and power. Built as a small-footprint clipboard history manager, clipLogger collects past clipboard entries, indexes them for fast retrieval, and adds filtering and organizational features — all while prioritizing security and minimal system impact.
What clipLogger does
clipLogger captures clipboard events (text, and optionally simple metadata like timestamps and source app) and stores them in a local, searchable history. Instead of replacing the clipboard with a single ephemeral value, clipLogger provides a time-ordered list of previous entries you can revisit, reuse, or permanently delete. Key functionality typically includes:
- Lightweight background operation with low memory/CPU overhead.
- Instant search and quick paste for recent clips.
- Persistent local storage with manual or automatic pruning policies.
- Basic organization: pinning, labeling, and favorites.
- Privacy controls: secure storage, optional encryption, and exclusion zones.
Why privacy-first design matters
Clipboards often carry sensitive content: passwords, personal messages, tokens, code snippets, or financial data. A clipboard manager that stores this history increases convenience but also raises risk. clipLogger is designed on the principle that you should control what gets stored and how long it remains:
- Local-only storage: by default clipLogger stores history only on the local machine; no cloud sync unless explicitly enabled.
- Selective capture: define exclusion lists (apps or window titles) where clipboard capture is disabled.
- Per-entry encryption (optional): entries can be encrypted with a local key or passphrase.
- Auto-forget rules: expire or auto-delete sensitive entries after a configurable time.
- Secure deletion: when an entry is deleted, metadata and content are purged from storage rather than merely unlinked.
These choices reduce surface area for data leaks and make clipLogger safer for use in privacy-conscious environments.
Core features in detail
Searchable history
- Full-text search across clips with fuzzy matching and support for regular expressions for advanced users.
- Quick filters (recent, pinned, favorites, images/text-only).
Quick paste and keyboard-driven interface
- Global hotkey to open the history overlay, navigate with arrow keys, and paste with Enter.
- Configurable behavior: paste directly into the active app, copy back to clipboard for manual paste, or simulate paste with OS-native events.
Organization and tagging
- Pin frequently used entries to the top.
- Add tags or short notes to clips for categorization.
- Collections or folders for grouping related clips (snippets, code, templates).
Import/export and interoperability
- Export selections or entire history to encrypted archives or plain JSON/CSV for backup.
- Import clips from other clipboard managers or plain text files.
- Integration hooks (e.g., templates for text expansion engines, or simple command-line interface).
Security controls
- End-to-end encrypted sync (opt-in) for cross-device continuity, using user-managed keys.
- App-whitelist/blacklist to prevent capture in secure apps (banking, password managers).
- Screen-obscure mode (hides clip preview on overlay when screen is being recorded or mirrored).
Performance and footprint
- Efficient on-disk storage using compact binary or SQLite with pruning and size caps.
- Lazy-loading UI that scales to tens of thousands of clips without lag.
- Minimal startup time and optional launch-on-demand rather than persistent background service.
Typical use cases
- Developers who reuse code snippets, commit messages, and stack traces.
- Writers and researchers collecting quotes, references, and short excerpts.
- Customer support agents with canned responses and troubleshooting steps.
- Designers and content creators who copy color codes, class names, or short captions.
- Anyone wanting an undo history for accidental clipboard overwrites.
Security best practices for users
- Configure exclusion zones for apps handling secrets (password managers, banking apps).
- Use auto-expiry for sensitive entries and enable secure deletion.
- If syncing across devices, prefer user-managed keys and strong passphrases.
- Periodically audit and purge old clips; use tags to identify ephemeral vs. permanent content.
Example configuration recommendations
- Default retention: 30 days for general clips, 24 hours for entries tagged “sensitive.”
- Max history size: 5,000 entries or 200 MB, whichever is smaller.
- Hotkey: Ctrl+Shift+V (customizable) to open overlay and paste quickly.
- Exclude: apps whose window title matches “1Password”, “LastPass”, “Bank”, or other known secure apps.
Architecture overview (high level)
- Clipboard listener: platform-specific component (macOS: NSPasteboard change count; Windows: SetClipboardViewer/ClipboardNotification; Linux: X11/Wayland integrations) that captures clipboard events.
- Storage layer: compact, indexed database (SQLite or specialized binary log) with encryption support.
- Overlay/UI: lightweight, keyboard-centric overlay for search and paste.
- Policy engine: rules for capture, exclusion, auto-expiration, and encryption.
- Sync module (optional): end-to-end encrypted replication using user keys.
Comparison with alternatives
| Feature | clipLogger | Typical clipboard managers |
|---|---|---|
| Local-only by default | Yes | Often no (cloud sync) |
| Per-entry encryption | Optional | Rare |
| Exclusion zones | Yes | Varies |
| Lightweight footprint | Yes | Varies; some are heavy |
| Keyboard-first UX | Yes | Many offer it |
Limitations and trade-offs
- Disabling cloud sync reduces convenience when switching devices.
- Per-entry encryption adds complexity for search and indexing (requires careful design to allow searching without exposing plaintext).
- Exclusion zones rely on correct identification of sensitive apps and may require user tuning.
Getting started (quick guide)
- Install clipLogger for your platform (native package or portable binary).
- Set a global hotkey and enable overlay on first run.
- Configure exclusion list and retention policy before heavy use.
- Optionally enable per-entry encryption or encrypted sync if you need cross-device access.
- Use tags and pinning to keep frequently-reused clips handy.
Roadmap ideas
- Secure snippet templates with variables and placeholders.
- Rich content support: images, files, and formatted text with secure previews.
- Machine-learning-powered suggestions to promote frequently used clips contextually.
- Native browser extension to capture content with richer context metadata.
clipLogger aims to be the clipboard manager you barely notice—until you desperately need a lost snippet. By combining a small resource footprint, strong privacy controls, and keyboard-focused ergonomics, it’s designed for power users and privacy-minded individuals who want fast access to their clipboard history without compromising security.
