How Sync Works
Last updated: 1/24/2026
We Don't Access Your Clipboard
QuickClip never automatically reads your device clipboard. You're in complete control—you manually add items by typing or pasting into our app, then clicking to save. We only write to your clipboard when you click the copy button on a saved item.
Think of QuickClip like a cloud notebook for your clipboard—you choose what to save, and it syncs across your devices. We don't monitor or track what you copy elsewhere on your device.
Built for Everyday Use
QuickClip is designed for everyday clipboard content like text, links, code snippets, and notes. It's built to be fast, reliable, and convenient—the kind of tool you use dozens of times a day without thinking about it.
How Your Data Is Protected
All your text content gets encrypted before it's stored in our database. We use AES-256 encryption, which is the same standard used by banks and cloud services. Each user has their own unique encryption key, so your data is isolated from other users.
Your encryption key is derived from a master key plus your user ID using PBKDF2 (a secure key derivation function). This means even if someone got access to the database, they couldn't decrypt your data without your specific key.
How Syncing Works
When you copy something:
- Your text gets encrypted on our server using your unique key
- The encrypted data gets stored in our database
- When you need it on another device, we decrypt it and send it to you
This is standard cloud sync encryption—the same approach used by most productivity tools. It's designed for speed and convenience while still protecting your data.
About Images and Files
Images and files work a bit differently. We don't encrypt the actual files—that would be inefficient and slow. Instead, files get uploaded to secure storage (Supabase Storage) and we store the URL in the database.
Those storage URLs are protected by:
- Private buckets (not publicly accessible)
- Signed URLs that expire after a year
- User-specific folder permissions (you can only access your own files)
So while the file URLs aren't encrypted, they're still secure. Files are stored in private buckets with user-specific permissions.
What We Can See
We can see metadata—when you created items, how many items you have, your account info. We can decrypt your encrypted content because the server needs to decrypt it to sync it across your devices.
We don't log your decrypted content. We don't analyze it. We don't sell it. We just store it encrypted and sync it when you ask us to.
Designed for Speed
We chose server-side encryption because it balances security with usability. Your data is still encrypted, but you don't have to manage keys or worry about losing access to your clipboard history. It's the same approach used by cloud sync services you probably already use.
This means syncing is fast, reliable, and works seamlessly across all your devices without any manual setup or key management.
Our Approach
I built this app because I needed a better clipboard manager. I'm not a big corporation trying to mine your data. I'm just a developer who wants to build something useful.
That means:
- We encrypt your data because it's the right thing to do
- We don't read your content because we don't need to
- We don't sell your data because that's not our business model
- We're transparent about how things work because you deserve to know
Best Practices
QuickClip is designed for everyday clipboard content like text, links, and notes. For highly sensitive data like passwords, credit card numbers, or personal identification information, we recommend using a dedicated password manager or secure vault.
Think of QuickClip like a cloud sync service for your clipboard—great for productivity, not designed as a secrets vault.
Questions?
If you have specific questions about how we handle data, hit me up through the contact form. I'm happy to explain anything in more detail.
At the end of the day, we're doing our best to keep your data safe while making the app actually useful. QuickClip is built for speed and convenience—the kind of tool that just works when you need it.
