How private are these tools?
Very. The numbers you type and the files you upload never leave your browser - all calculation and PDF generation happens locally. We don't have a server-side database for any of this: no signup, no account, no cloud sync. Your vendor list and recent documents save to your browser's localStorage only. The one caveat: anonymous page analytics (which page you viewed, not what you typed) fire if you accept the cookie banner, and not otherwise.
Frequently asked questions
Do I need to sign up or pay?
No. Every tool here is free, browser-based, and requires no email or account.
Where do my numbers go?
Nowhere. Each tool runs entirely in your browser. Saved vendors, customer lists, and recent documents live in your browser's localStorage on your device. We have no server-side database for any of these tools.
Can I use these PDFs commercially with my customers?
Yes. The PDFs are watermark-free and yours to use. There's a small "Generated with SimpleGrid productive tools" line at the bottom - you can remove it by editing the PDF if you want.
What happens when I outgrow these tools?
You'll know. The moment you find yourself opening four of these tools to track one customer order, you're already running an ERP - just one stitched together. That's the moment SimpleGrid pays back. See how pricing works →
Where did all the other tools go?
We used to ship 140+ tools. We cut the catalog hard - then put back the ones earning their keep, ending at 35. The retired tools redirect here. If one of them was solving a real problem for you, email [email protected] and tell us which - if enough people ask for it, it comes back.
