DevSuite
At a glance
DevSuite is built so your data stays on your computer. This page explains the little that ever leaves it.
1Local processing
Everything you copy, inspect, format or view runs 100% on your computer. DevSuite does not upload your images, clipboard contents, files, queries, logs or results. Copy writes the selected content to your system clipboard.
Text recognition (OCR) uses the recognition built into macOS or Windows, on your computer; the Linux version has no OCR yet. Commands, requests and webhooks you paste are read, never sent.
DevSuite saves only its settings on your computer (such as theme, font size and favourite tools), never what you pasted.
2What leaves your computer
| Data | Where it goes |
|---|---|
| What you paste, open, format or convert | NOWHERE It stays on your computer. |
| Clipboard contents | NOWHERE Read only when you ask; no history is kept. |
| Usage, analytics, crash data | NOWHERE DevSuite collects none. Apple or Microsoft may, only as your system settings allow (see below). On Linux, nothing. |
| Mac license key | LEMON SQUEEZY Your key and your Mac’s name, to activate it and check it about every 12 hours. See section 5. |
| Mac update check | OUR DOWNLOAD SERVER A daily request for the update feed. It carries no information about you or what you paste. See section 6. |
| Windows trial and purchase | YOUR STORE Handled by the Microsoft Store under your account. We never see your payment details. On Linux, DevSuite is free: there is no trial or purchase. |
3Clipboard
Mac. DevSuite reads the clipboard only when you paste into it (⌘V or Edit → Paste). It never watches the clipboard in the background and has no setting that would.
Windows and Linux. DevSuite reads the clipboard only when you paste, press its shortcut, or turn on clipboard detection in Settings.
DevSuite keeps no clipboard history on any platform.
4Analytics and API calls
DevSuite does not collect usage analytics and does not send your content to tracking services or AI APIs. There is no account and no sign-in.
5Purchases and free trial
Mac. DevSuite for Mac is free for 14 days, counted on your Mac; starting the trial sends nothing. To keep using it, you buy a license from Lemon Squeezy, which sells DevSuite for us as merchant of record and handles payment, tax and receipts under the Lemon Squeezy Privacy Policy. We receive the name and email address on your order so we can help you with it; we never see your card details.
When you enter your key, DevSuite sends Lemon Squeezy the key and a name for this activation, made from your Mac’s name (for example “DevSuite on Ada’s MacBook Pro”), so you can tell your activations apart. About every 12 hours it asks Lemon Squeezy whether the key is still valid, sending the key and the activation’s ID. If your Mac is offline, DevSuite keeps working for 72 hours before it asks you to reconnect. The key is stored in your Mac’s Keychain.
Linux. DevSuite for Linux is free. There is no trial, purchase, licence check or account, so it has nothing to send or check.
Windows. Microsoft handles the free trial and the one-time purchase through the Microsoft Store, under your Microsoft account and the Microsoft Privacy Statement. We never see your name, email address, Microsoft account or payment details.
6Updates and network
Mac. You download DevSuite from downloads.byquan.app, our download server on Cloudflare. Once a day DevSuite fetches the signed update feed from the same server (you can turn this off in Settings → About), and it downloads an update only when you agree to install it. These requests carry no information about you, your Mac or what you paste; like any web request, Cloudflare sees your IP address. Every update is signed by us and notarized by Apple, and DevSuite refuses one that isn’t.
Apart from that update check and the license requests in section 5, DevSuite for Mac makes no network requests. Everything else works offline.
Windows. The Microsoft Store delivers updates. Apart from the purchase and restore requests the store makes for it, DevSuite for Windows makes no network requests of its own.
On Linux, Flathub or the Snap Store delivers DevSuite and its updates; they may count downloads under their own privacy policies. DevSuite for Linux runs in a sandbox with no network access at all. The Donate button in Settings only opens Ko-fi in your browser.
Apple may share crash reports and usage data with developers only if you opt in to that in System Settings → Privacy & Security → Analytics & Improvements. On Windows, diagnostic data follows your Windows privacy settings.
