CopyFlow — Clipboard Manager

Tired of losing things you copied 5 minutes ago? CopyFlow saves every piece of text you copy and keeps it searchable, organized, and always available — with optional encryption so even your clipboard stays private. WHAT COPYFLOW DOES • Automatically saves everything you copy — text and images • Search your entire clipboard history instantly • Pin important clips so they stay at the top • Edit saved clips directly in the popup • Organize clips into color-coded folders • Right-click any text field to paste from your history • Text snippets — type a short trigger (e.g. ;sig) and it expands automatically • Visual copy confirmation — brief on-screen toast every time you copy • Keyboard navigation — j/k to move, Enter to copy, / to search • Export and import your clips as JSON backups • Dark mode and light mode • Keyboard shortcut (Alt+Shift+V) to open instantly NEW IN v0.3.0: SMART DETECTION & SYNC • Smart content detection — auto-detects URLs, emails, code, JSON, phone numbers, colors, and sensitive data (API keys, tokens, passwords) • Color-coded badges — each clip shows its detected type at a glance • Filter by type — click a badge to show only URLs, code, sensitive data, etc. • Sensitive data alerts — warns before pasting API keys, tokens, or credentials to unfamiliar websites • Encrypted Chrome sync — sync pinned clips and snippets across devices, fully encrypted with your password • "Remember this site" — suppress paste warnings for sites you trust OPTIONAL ENCRYPTION Enable a password to protect your clipboard with AES-256-GCM encryption (the same standard used by banks and password managers). Your data is encrypted locally — CopyFlow never sees your password or your clips. • AES-256-GCM encryption, 600,000 PBKDF2 iterations (OWASP 2023 standard) • Auto-lock after inactivity • All existing clips migrated automatically when you enable encryption • Encrypted sync across devices (same password required on all devices) • Export still works — decrypts to portable JSON for backups WHY COPYFLOW? Most clipboard managers ask for permissions they don't need — like your full browsing history. CopyFlow only requests the minimum required to do its job. No analytics. No tracking. No account. No cloud. Your data stays on your machine. Always exportable. Never locked in. PRIVACY FIRST • No browsing history access • No data sent to any server — ever • No account required • All clips stored locally in your browser • Optional AES-256 encryption at rest • Export your data anytime as a JSON file PERMISSIONS EXPLAINED • clipboardRead/Write: Read and write to your clipboard (the core feature) • storage/unlimitedStorage: Save your clip history locally on your device (unlimited storage for large image histories) • offscreen: Required by Chrome to access the clipboard in the background • activeTab/tabs: Record which page you copied from (shown as source info on each clip) • contextMenus: Right-click paste menu in text fields CopyFlow is free and open source. Built by a solo developer who was tired of losing copied text.
