Privacy Policy
Last updated: February 2026
Overview
DevKit is designed with privacy as a core principle. We do not collect, store, or transmit any of your data. Every operation happens entirely on your device.
No Data Collection
DevKit does not collect any personal information, usage data, or analytics. We have no servers that receive your data. The app does not contain any tracking SDKs, analytics frameworks, or advertising libraries.
On-Device Processing
All data processing in DevKit happens locally on your iPhone or iPad. When you format JSON, decode Base64, or use any other tool, the data is processed entirely on your device. Nothing is sent to any external server.
No Network Requests
DevKit makes no network requests during normal operation. The app works completely offline. The only network activity occurs when you download the app or its updates from the App Store, which is handled by Apple.
No Analytics or Tracking
We do not use any analytics services (such as Google Analytics, Firebase, Mixpanel, or similar tools). We do not track which features you use, how often you use them, or any other behavioral data.
No Third-Party Services
DevKit does not integrate with any third-party services that could access your data. There are no social media SDKs, no crash reporting services, and no advertising networks.
Data Storage
Any data you enter into DevKit stays on your device. We do not use iCloud sync or any other cloud storage mechanism to transmit your data off your device.
Children's Privacy
Since we do not collect any data from any users, we also do not knowingly collect data from children under the age of 13.
Changes to This Policy
If we make any changes to this privacy policy, we will update the date at the top of this page and provide notice through the App Store update notes.
