Keep it free for everyone
Every tool, calculator, game and practice exam on KSRM.digital is free — and always will be. No paywalls, no "premium", no catch. We built this so a family's budget never decides a child's chances.
We're not here to get rich
We don't sell your data, we don't lock features behind a payment, and we never will. The only thing it costs us to run is a small monthly hosting bill. If KSRM has helped you and you're able to, an entirely optional one-off tip helps cover that — so we can keep everything free for the people who can't pay. If you can't, that's completely fine: just use the tools, that's what they're for.
100% optional. Pay what you like, or nothing at all.
How you can really help (free)
- Share a tool that helped you — with a friend, a parents' group, a student forum. That's worth more than money: it helps someone else who's struggling.
- Tell us what to build next via the contact page — especially if there's something expensive out there that should be free.
Our promise
- ✓ Every tool stays free, forever — no feature is ever moved behind a paywall.
- ✓ No sign-up required to use anything.
- ✓ Your files and data stay on your device — we don't collect or sell them.
