No Personal Data on Our Servers
We do not store any of your personal data on our servers. All your revision data, progress, nicknames, and settings are stored locally in your browser using IndexedDB. This means your data stays on your device and is never transmitted to us.
Anonymous Usage Statistics
We collect anonymous usage statistics to understand how the app is used and improve it. This data is stored on our own servers - not with any third-party analytics companies. We do not collect your nickname, revision content, or any personally identifiable information. We only track anonymous events like "a revision session was completed" or "a PLC was imported".

Google Drive Backup (Optional)
If you choose to use the Google Drive backup feature, your data is saved directly to your own Google Drive account. We never see or have access to this data. The backup is stored in your Drive's app data folder, which only you can access.
About Your Nickname
The nickname you set in the app could be considered personal data. However, it's designed to be a nickname rather than your real name - you can use any name you like. This nickname is only stored locally in your browser and, if you use the backup feature, in your own Google Drive. We never see or collect this information.
Local Storage & Cookies
We use your browser's local storage to save your preferences (like dark mode, dismissed tips, and widget settings). No tracking cookies are used. Your revision data is stored in IndexedDB, a browser database that keeps everything on your device.
Deleting Your Data
You can delete your data at any time using the options in Settings (accessible from the app menu). You can also clear your browser data or use the browser's developer tools. If you've backed up to Google Drive, you can delete that backup directly from your Google Drive account.
In Summary
Your personal data is yours. We don't collect it, store it, or have any access to it. Everything stays on your device or in your personal Google Drive. We only collect anonymous usage statistics to improve the app.
