Introduction

Many of the tools on this site store your information directly in your browser using local storage or IndexedDB. This keeps your data private — nothing is uploaded or stored on external servers — but it also means your browser is responsible for holding onto everything you enter.

Because browsers can sometimes delete stored data automatically, it’s important to understand how to back up, restore, and reset your information safely.

Why Backups Matter

Browser-stored data can be lost for several reasons, including:

• Clearing your cache or site data
• Switching browsers or devices
• Private or incognito browsing sessions
• Automatic browser cleanups (common on mobile devices)
• Storage resets after browser updates
• Low-storage conditions where the browser evicts data

For this reason, it’s a good idea to export your data regularly — especially after making significant updates.

Exporting Your Data (Recommended for Backup)

Exporting creates a downloadable .json file containing all the information saved within a specific tool or calculator.

You should export your data when:

• You want a secure backup
• You plan to switch devices or browsers
• You are about to clear your browsing data
• You’ve made important updates you don’t want to lose
• You want to share your setup with another device you use

Your exported file stays on your device and is never uploaded anywhere.

Importing Your Data

Importing allows you to restore a previously exported .json file.

Use this option if:

• You’re setting up the tool on a new device or browser
• You’ve reset your browser data and want to recover your information
• You want to keep multiple devices or browsers in sync

If the file is valid, the tool will immediately reload your saved information.

If the file is invalid or corrupted, you’ll be shown an error page with options to:

• Export your current data (if any is still recoverable)
• Clear all stored data and then try importing again when the calculator loads

Clearing Data

The Clear option deletes all information saved in your browser for that specific tool or calculator.

This can be helpful if:

• You want to start over from scratch
• You imported incorrect or corrupted data
• You ran into an issue and need a full reset

You’ll be asked to confirm before clearing — and you always have the chance to export your data first.

Summary

The Export, Import, and Clear features give you complete control over your data while keeping everything private and stored on your device. By exporting regularly and keeping backups, you can protect yourself from unexpected data loss and seamlessly move between browsers or devices whenever needed.
