Privacy Policy

Effective 12 November 2026

In short: StackPad collects no data. The app works entirely offline on your Mac. It has no accounts, analytics, advertising or tracking, and it never sends what you type, paste or open anywhere.

This policy covers the StackPad app for macOS and this website. StackPad is developed by Oleksandr Ivanchyk (“we”, “us”). If you have a question about it, contact us at ivanchyk.oleksandr.dev@gmail.com.

Information we collect

None. We don't collect, receive, store, sell or share personal information or usage data, and the app contains no third-party analytics, advertising, crash-reporting or tracking code. On the App Store, StackPad's privacy label is “Data Not Collected”.

The app works offline

StackPad runs in the macOS App Sandbox without permission to make network connections, so it cannot send anything over the internet. Everything a tool does, such as formatting JSON, decoding a token, hashing text or converting an image, happens on your Mac.

What stays on your Mac

StackPad keeps a small amount of information locally, inside its own sandbox container, so it works the way you left it:

• Menu preferences: which tools you've hidden and the order you've arranged them in.
• Saved inputs: when you choose Save in a tool, the name you give and the text of that tool's input. Nothing is saved unless you ask for it.

This information never leaves your Mac and isn't synced to iCloud or any other service. You can delete a saved input from the tool's Load dialog, reset the menu from Customize menu, and uninstalling StackPad removes all of it. Backups you make yourself, such as Time Machine, may include it as they include other app data.

Text you type into a tool but don't save is kept only in memory while the app is open.

Files, the clipboard and links

• Files: StackPad only reads a file you pick in an Open dialog or drag onto it, and only writes a file where you choose in a Save dialog. Files are processed on your Mac.
• Clipboard: StackPad only writes to the clipboard when you press a Copy button.
• Links: clicking a link, for example in Markdown Preview, opens it in your web browser. What happens there is governed by that website's own policy.

This website

This site is a set of static pages hosted on GitLab Pages. It uses no cookies, analytics, advertising or third-party scripts and fonts, and it has no forms. Like any web host, GitLab may process technical information such as your IP address to deliver the pages and keep the service secure; see the GitLab Privacy Statement.

Email

If you email us, we use your address and message only to reply to you and to improve StackPad, and we don't share them with anyone. Tell us if you'd like your messages deleted.

Children

StackPad doesn't collect personal information from anyone, including children.

Changes to this policy

If this policy changes, we'll update it on this page and change the effective date above. If StackPad ever starts handling data differently, the policy will say so before that version is released.
